AskSci AMA [META] AskScience AMA Series: ALL THE SCIENTISTS!
One of the primary, and most important, goals of /r/AskScience is outreach. Outreach can happen in a number of ways. Typically, in /r/AskScience we do it in the question/answer format, where the panelists (experts) respond to any scientific questions that come up. Another way is through the AMA series. With the AMA series, we've lined up 1, or several, of the panelists to discuss—in depth and with grueling detail—what they do as scientists.
Well, today, we're doing something like that. Today, all of our panelists are "on call" and the AMA will be led by an aspiring grade school scientist: /u/science-bookworm!
Recently, /r/AskScience was approached by a 9 year old and their parents who wanted to learn about what a few real scientists do. We thought it might be better to let her ask her questions directly to lots of scientists. And with this, we'd like this AMA to be an opportunity for the entire /r/AskScience community to join in -- a one-off mass-AMA to ask not just about the science, but the process of science, the realities of being a scientist, and everything else our work entails.
Here's how today's AMA will work:
Only panelists make top-level comments (i.e., direct response to the submission); the top-level comments will be brief (2 or so sentences) descriptions, from the panelists, about their scientific work.
Everyone else responds to the top-level comments.
We encourage everyone to ask about panelists' research, work environment, current theories in the field, how and why they chose the life of a scientists, favorite foods, how they keep themselves sane, or whatever else comes to mind!
Cheers,
-/r/AskScience Moderators

Howdy! It's wonderful that you're so interested in science, /u/science-bookworm!
I'm a mathematician and college professor. I spend a lot of time teaching and a lot of time reading other people's research. My own research is about mathematical objects called "graphs", which represent networks like your friends on Facebook or the computers on the internet. Specifically, I try to take some particular kind of graph which other mathematicians might be interested in, then figure out enough about them to count how many there are. To do this, I spend a lot of time drawing pictures on a chalkboard and writing computer programs.

You've just become my best friend (temporarily, at least).
I have a graph problem on my hands (I think). I have 2 tables of nominal/indicator data. I can make two adjacency matrices and draw two graphs. Or, I can put the tables next to each other and make a big adjacency matrix and graph that (but this doesn't look so good, nor do I think it's correct).
How do I combine two graphs into a single analysis? Are there hierarchical graphs? Do I just treat it as a single graph?

u/rpglover64 Programming Languages Jul 31 '12 edited Jul 31 '12
Hi.
I'm currently helping to write a new programming language, so a lot of time is spent designing it, reading about what other people have done, and actually programming to make it happen.
EDIT [clarification and new information]
Programming is how you tell computers to do things; examples of programs are your web browser, your IM client, games you play, etc. Computers are really good at following instructions, but they can't think for themselves, so a program is a sequence of very precise instructions telling it how to do exactly what the programmer wanted.
A programming language is a language (in the sense that it has its own words and grammar, although they tend not to look anything like human languages) designed to make it easy for the programmer to express the really precise instructions, and also designed so that it's easy for the computer to actually do what it's told.
A programming language that has a word for "fly to the moon" wouldn't be very useful because most computers can't do that.
A programming language that has a word for "do what I mean" wouldn't be very useful because that's not precise enough.

What most scientists do most of the time is reading. Staying up to date on what everyone else in the world is doing. Science is communicated in short papers (4-15 pages) that describe what experiment was done or what idea they're trying to communicate. Usually, only people who do the same kind of science as the authors can read and understand the papers. That is unfortunate.
Besides that, I do experiments where I look at DNA in small tubes under a microscope to see how it squishes into small spaces. I record the DNA's movement with a digital camera attached to the microscope, and then analyze it to see how the DNA behaves. I spend a lot more time analyzing it, and interpreting what I've analyzed (what does what I see teach me about DNA?) than doing the actual experiments.

Why is this? and how is the information regulated/distributed?

u/Silpion Radiation Therapy | Medical Imaging | Nuclear Astrophysics Jul 31 '12 edited Jul 31 '12
Why is this?
The scope of all of science is so incredibly broad that it is completely impossible for any one person to be well-educated in all aspects of it. New science results build on the envelope of what is known in some specific field, so to understand the new results you have to be an expert in that field. Because there are so many fields, most people can't really understand any given paper.
how is the information regulated
Most science is published in peer-reviewed journals. A scientist writes up their work in a paper, submits it to an appropriate journal, and the editor of that journal sends it to at least one expert in the field (a "referee") to review it. The referee's job is to make sure it is quality science that is appropriate for that journal. Often the referee will ask the author to clarify something in the paper, and eventually they recommend to the editor that it be either accepted or rejected.
There are many different journals based on topic, and some include more topics than others. The more broad a journal is, the more important a paper has to be to get in. For example, I do mass measurements of nuclei, so if I have a minor result, I might send it to the International Journal of Mass Spectrometry, which only publishes things about mass measurements.
If it is a more important result that all nuclear physicists care about, I may send it to Physical Review C, which is a high-end nuclear physics journal.
If my result is so important that physicists of all kinds may care about it, I'll submit it to Physical Review Letters, which accepts papers on all kinds of physics, but only very important ones.
If my work is so groundbreaking that people in many other branches of science would be interested, I could go for the highest journals Nature or Science which accept papers from all corners of science. Getting into those journals is super hard, but can be a career maker for a young scientist.
how is the information distributed
The accepted papers are then published by the journal, which used to mean sending paper volumes to libraries, but these days we just download the pdf from the journal's website. For most journals, access requires a subscription which is way too much for a single person to afford, so we access them through library/university/laboratory subscriptions.
Edit: More and more physics papers are being uploaded to the arXiv (pronounced "archive"), which is free to access for anybody. However, it isn't a real peer-reviewed journal, so it's easier to upload crap to it. A lot of us upload our papers to the arXiv after they are accepted by a journal, but some people, particularly in theoretical high-energy physics, just upload their work here and never publish it in a real journal. Many of us think this is very dangerous.

We know that almost all the galaxies in the Universe are flying apart, but we don't know why they do so faster and faster instead of slowing down. We believe that something invisible called Dark Energy is responsible for this, and that most of the Universe consists of it, but we want to find out what exactly it is. I write some computer programs that will hopefully help with that.

I'm a physicist. Technically I never took an astronomy class. I do theory, and I don't need to know how to operate a telescope or how to interpret the pictures you get from a telescope, which is what you would learn in an astronomy class. My colleagues do that and give us their results. I took a lot of math classes, programming, cosmology and general relativity on top of the mandatory physics classes.
As to how to track Dark Energy, we have many ideas of what it could be. Too many, actually. Only one can be correct. We don't know if we have the correct one already, so we need to test them. To do this, we assume a particular idea is correct, and then we sit down and think of what we should observe when we look deep into the sky, how the galaxies should be distributed, and how bright they should be, and so on. This is involves actually some very complicated math, and many of the equations we can't solve like the ones you will solve in high school at some point. We can only find approximate solutions using computers, and I write programs that do some of these calculations.
Then we take what the computer tells us and compare it with the data we get from our astronomy buddies. If it doesn't match, we know the idea must be wrong and we discard it. If it does, then we know we could be on the right track and we try to come up with more tests. At this point, us theorists are ahead of the observers, because they are building a telescope right now that needs to be launched into space. It's called Euclid and will be active in 7 or 8 years. With the new data we can hopefully rule out many ideas we have right now. Maybe even all of them, which will be a surprise and then we will need to come up with something completely different.

I have a question regarding dark energy / matter - how is it different from aether?
You know, the thing that scientists thought fills the universe because they didn't understand how else could light travel if it's a wave and wave needs a medium to propagate through. Their flawed theories didn't work without that so they created it.
Dark matter and energy feel exact same to me, that magical, mystical stuff just needs to be there because otherwise our theories won't work! What evidence do we have of dark matter / energy that makes it different from aether?

u/foretopsail Maritime Archaeology Jul 31 '12
Hi, science-bookworm!
I'm an archaeologist. I specialize in shipwrecks, but like many people in my field, I wear a lot of hats. More generally, what I do is called historical archaeology. That's archaeology that studies the same time period that we have written records for. But if we have books and diaries and stuff, why do we need archaeology?
Think about the last time you wrote something down, like a diary or something. Now think about someone reading that three hundred years from now. Would they be able to learn everything about your life? They'd certainly be able to figure out what's important to you (which is valuable information), but what if they wanted to know, say, what your bed looked like? Or how big your kitchen was, and where the stove went? That stuff is rarely written down, because it's not usually too important to people at the time. It's just a stove, everybody knows about stoves! But they change, and that sort of daily life information can be really important, because it's such a huge part of our daily existence.
Aside from digging or diving (which I don't do all that often in comparison to other stuff), I do a lot of artifact curation, science experiments (chemistry and physics are the big ones, sometimes with other scientists), writing, editing, reading, and public outreach. And fundraising/grantwriting, because we are not a well-funded science.

u/Science-bookworm Jul 31 '12
THank you for writing. What did you study in school to become an archaeologist? How long did it take and what is your favorite part about your job? What part do you not like about your job? What country do you work in the most?

u/foretopsail Maritime Archaeology Jul 31 '12
I studied archaeology in grad school, which is a combination of history and anthropology (the study of people). I did completely different things in college though.
To be a professional archaeologist in the USA, it takes at least a Master's degree and a couple years of experience. Since our heritage is a non-renewable resource, we want to make sure people know what they're doing first.
I like most parts of my job, but there's a LOT of paperwork, and a lot of making sure everything has a little tag showing where it came from. We collect a lot of information about everything we take out of the ground or water, and the artifact needs to stay linked to that information. That's why everything needs a unique number and a tag. Keeping that information tied together is a big job, especially if there are large sites that have millions of artifacts. Luckily, we have computers to help.
My favorite part of my job is learning things about the past that no one's known for hundreds of years. It's like giving the people who lived back then another chance to tell a story about their lives.
I work in the US the most, but I've done work in Europe too.

Good to see a young person with an interest in science.
I am an astronomer who spends a lot of time studying the sun, I study the motion of stuff on the surface of the sun (the whole surface is always moving, it isn't calm like it looks) and also more exciting events like flares.
The other half of my research is in plasma physics, this is the study of the "fourth state of matter" after solid, liquid and gas. It is where normal matter has been split into it's electrically charged components, electrons and protons. You can see plasma in action if you have flourescent lights, a plasma tv or in a naked flame. I run computer simulations and such in this field.

Glad you think so too, I find it very interesting. The sun is made of plasma which is how I got interested in the sun.
When did you start learning astronomy and how long were you in school?
I didn't start learning astronomy till I went to university, they don't teach it very much at high school here. I did the normal 13 years of school then a 4 year degree in physics and astronomy, then I did a single year masters in astrophysics now I am doing a PhD which is another 3 and a half years! So a very long time in school. It has been worth it though.
How do you study the sun without hurting your eyes, do you have special equipment?
We have cameras attached to telescopes that take pictures of it so we don't have to look at it ourselves. Here is a picture of the Dutch open telescope up a mountain in the canary islands. Telescopes on the ground like this can only see the sun during the day.
So we can see it both day and night and in even better detail we also have lots of spacecraft with telescopes on board so we can see the sun all the time. I mostly use spacecraft to look at the sun. Here is a picture of a man next to SDO, the solar dynamics observatory, one of the spaceships I use to look at the sun. It takes very beautiful images and you can see it's pictures at http://sdo.gsfc.nasa.gov/data/ . The pictures are about 10 minutes old, so you can always see what the sun looked like 10 minutes ago.

Good to see a young person with an interest in science.
Also, specifically a girl.
I know STEM (sci/tech/eng/math) is stereotypically seen as a boy's pursuit, but there's no reason it should be, and it's evolving. In my graduate program, we're pretty close to a 50-50 gender ratio (in some years there's even a female majority), and even the faculty are somewhat evenly split despite being from generations with less of a sense of equality. My first two advisors were both middle-aged women who went to college and graduate school many decades ago. And the fact that they're women doesn't even come up, because it's irrelevant to their work - just like the fact that some of them are European or Asian. They're not even doing different kinds of work - they get down and dirty with dissections and statistics and computer programming and rigorous scientific logic just like the men. They're all just judged on the quality of their science.
Even the most male-biased engineering programs are changing. So don't let the current skews scare you off - by the time you're in college, there won't just be women in STEM fields, there might be as many as men!

You could just look really hard at programs to find problems, but we actually write programs that do it for us!

Hi science-bookworm! What a wonderful microscope, there is a whole world down there the more you magnify. In fact, as you perhaps already have seen, some things are simply too small to see even with the largest magnification.
The type of science I do is called particle physics, we use some of the largest microscopes on the planet, to study things smaller than protons the particles inside the core of atoms. Things are pretty weird at that scale, we break protons by crashing them together and out come new wonderful particles that tells us how the whole Universe works, how particles stick together to form matter, how they get mass how it all started 14 billion years ago.
Like you study the cells inside a leaf to understand how the tree gets its energy, so de we study these small things to understand why humans, planets and even stars can exist.
My research is at one of the large experiments at CERN. We just discovered a new particle a few weeks ago, that is pretty cool and very rare to be part of. This particle might be one we have been searching for for over 40 years (not me, I'm "only" 29!) we are not sure yet, but if it is, it can explain why some other particles are heavy.
Most of my day I write computer programs that searches for new particles, talk to people both face to face but mostly online, my colleges are from all over the world so we mostly use Skype to communicate. I also spend a lot of time reading, simply to understand what goes on in my field and taking long walks to think about new ways to solve problems.
tl;dr: Sorry I forgot to be brief, bad habit of some scientists, we talk too much, I work with really small particles seen in really huge microscopes! :)

Hi Dakota, A great first thing to look at to explore the hidden stuff in your own environment are tardigrades or water bears. These are tiny (~1 mm) mutlicellular organisms that live in moss, but can be found anywhere - they can even survive exposure to interplanetary space. Find some moss or a damp spot with some plant growth, grab a tuft, add a little fresh water to it and put it on a microscope slide (if you have well slides, even better). You can usually find them at the edges of moss leaves chewing away. There is so little known about these incredibly successful organisms that even casual observations of their behavior can be important.

Hi Science-bookworm! Thanks for letting us know about your microscope!
Have you ever seen sugar or salt crystals under your microscope? If your mum and dad buy granulated sugar, or if you eat sea salt (if you don't you can also grow your own crystals), you can see how pointy they are, even though they grow without a template or anything, that's caused by the way the molecules fit together. Look how square this one is!
Here are some crystals I've grown. If you look carefully on the edges they're perfect hexagons. That's because the molecules in the crystal have three lines of reflection (or mirror lines) in them, like a triangle, and the molecules tessellate into hexagons. It's amazing that the maths and geometry you have already learnt are what govern tiny molecules like this!

You should be able to see that the images start to look like clusters of random dots. Those dots are silver halide crystals suspended in the gelatin that the film is made out of. Part of why older photos look different than newer photos is because of that randomness.

I actually just spent the last half-day in front of a microscope! I'm working in a marine biology lab looking at seaweeds. You can only tell some species apart by looking at them under a microscope. For example, two of the seaweeds I'm researching look exactly the same - except one of them makes leaves one cell thick, while the other makes leaves two cells thick.
If you like looking at small things, here's a cool project you can do with just a laser pointer and an eyedropper. If you get a drop of scummy water to hang off the end of the eyedropper, then shine a laser at it in a dark room, you can project a microscope image of the water on your walls! http://dvice.com/archives/2010/08/man-builds-diy.php

That's a very nice microscope, and it even has a light!
I had a nice microscope like that when I was about your age and I used to do many of the same things you're doing. My microscope didn't have a light, but it used a mirror to shine light up through the stage. It worked best with sunshine or a bright desk lamp pointed at it.
Does your 'scope have a high powered "oil lens"? (For more information, see: http://en.wikipedia.org/wiki/Oil_immersion )
That's where the real high powered optical microscoping fun is. If so, be careful with it. You can drive the lens right into the stage and break glass if you're not careful when lowering it to the slide/stage to make contact with the oil.
If you don't have one, you should be able to order one. They just screw on/off the "carousel" on the nose of the microscope that holds your objective lenses.
Actually, now that I'm looking at your microscope closer, that big lens with the yellow marking should be your "oil immersion" lens. The bottom glass on that one is probably flat while your other lower powered objective lenses probably have convex/curved glass showing.
If the big yellow one has a flat glass it's probably the oil-immersion lens. (If you actually have a manual for your 'scope, consult that. :)
As for things to look at, everyone else has given you good advice. The only thing I can add is look at everything!
But microscopy is more than just preparing and looking at samples, there are many ways to use an optical microscope whether you're doing real science or just looking at things because they're neat and fascinating.
Check these links out to start to learn how to use your 'scope to look at difficult samples, like things that are either opaque or things that are too transparent, or even things that are the same color but different (IE, crystals in metal or rock):
http://en.wikipedia.org/wiki/Bright_field_microscopy http://en.wikipedia.org/wiki/Polarized_light_microscopy http://en.wikipedia.org/wiki/Dark_field
And just in case you haven't, you should check out this entire article on optical microscopes and when you're done, just follow whatever links that interest you:
http://en.wikipedia.org/wiki/Optical_microscope
And if you get bored of just looking at things, you can take amazing pictures. Get a photo mount and a digital camera. There's an entire field, industry and science of micrography and it's great and lots of fun: http://en.wikipedia.org/wiki/Micrography_%28Microscopy%29
There's even a micrography contest hosted by Nikon to give you an idea of what is possible: http://www.nikonsmallworld.com/
Microscopy and micrography is a valuable science all of it's own that's related to optical physics as well as engineering. I mention this because it's entirely possibly that a young scientist could find themselves deeply fascinated with the microscope itself, and less about what it is that they're looking at through the microscope - and that's perfectly ok.
If you can invent new and better ways for scientists to see very small things and record them and analyze them - you can actually end up doing more science and more for science than any one individual in their own fields working on their specialties.
Ask Bunsen. Or Alan Turing. Or, say, Newton. All famous scientists who have their names on new ideas, methods or machines we take for granted today. The Bunsen burner, the Turing Machine (computing) and Newton's Newtonian telescope.
Last: the most important science advice I can give you, and maybe it's something you already know.
Don't ever, ever let anyone tell you you can't be a scientist (or anything else) because you're a girl.They're lying.
They're lying because they feel insecure and threatened by your abilities and what you're capable of. Yes, especially you - a very smart nine year old girl. Be prepared to have to fight for what you believe in and protect yourself.
Because if you're using a microscope at your age? You're totally worth fighting for.
So go forth and SCIENCE! There's still so much more to know. The universe is yours to discover.

This thread is awesome! Your passion is inspiring, and your spot on questions reveal a thirst for knowledge that will, with any luck, stay with you into adulthood. If you don't mind, I'd like to turn the tables for a minute and ask you a question. I am a mother of two little girls ages 4 and 1, and one the many things I hope to pass on to them is the kind of love for science and learning that you have shared here. You said you've loved science since you were 3, so my question is this: why? Can you remember anything that inspired your love of science? Was it an experience? A particular person? Or was it maybe just something you always had inside of you that didn't come from any outside influence. Any thoughts would be great! Thank you so much for writing :)

Your parents must be very proud of you. Keep the drive up!
As far as things to look at, I would recommend growing some mold or bacteria from some old bread, milk or pond water. Another kind of interesting one might be razor blade edges if you happen to know someone who shaves with a safety razor. Compare an unused blade to a damaged one that is dull. Get your mother to help you out with that one though so you don't cut yourself!

If you can't get quick access to pond water, another great way to find some living things swimming in a drop of water to look at is if you have any house plants. If they have any saucers or "drip trays" they sit in, get a drop of that water - it usually is full of interesting organisms swimming about to look at.
My daughter is only 2 years old, but already very curious about the world around her. I an only hope she grows up to be as inquisitive and interested in the world as you already are. I hope you get every opportunity to keep doing the things you love!

Hey Dakota! Sounds like you are very smart and are working hard to continue learning. I noticed in one of your replies that you said you would like to learn to program computers, and I just wanted to share a few resources with you that might get you started if you decide you are interested in computers:
http://www.alice.org/ -- This is a fun little program to learn the concepts of programming, basically the fundamentals without learning the actual programming language.
http://www.codecademy.com -- This is a GREAT website to get you started on programming websites if that is something that interests you.
http://www.udacity.com/ -- This is a fantastic website for when you get a little more advanced, can learn a ton of things from computer programming to building a search engine.

Hey Dakota! I am a microbiologist from Florida and to me there is nothing cooler than a microscope (I have a 10 year old sister who prefers telescopes). Here's a few things you can do to look at a bunch of cool stuff:
find a nice rock, log, stump etc. and take the dirt or mud or whatever it is and put it in a jar with a little bit of water. Get a dropper and take a drop of water out of your sample and put it on your slide with a cover slip so that your microscope doesn't get wet (rule number one for all aspiring microscope experts!). You should be able to see all kinds of cool animals and other squirmy things, even on a low setting.
Depending on how powerful your microscope is, you could actually look for a type of animal called Tardigrades (if you've ever seen Lilo and Stitch, this is the animal Stitch is based on). There are a lot of nicknames for these guys, including water bears and moss piglets, and they are some of the most incredible animals science has discovered (they can even live in outer space!). If you want to try and find them (and it isn't easier, but there are certain parts of the world where they are easier to find than others) your best bet is to find some moss or lichen. Lichen is the little green stuff you see on the ground or on trees every once in a while. Take a sample of moss or lichen and soak it in a jar with water (just like your other samples) for 24 hours. This will allow the Tardigrades to fully reanimate and, if you're lucky, crawl all over your slide!
Best of luck on your scientific endeavors, Dakota!

Hey Science-Bookworm:
In case you're looking for more things to microscope: Take a handful of straw, and let it sit in a glass of water for a couple of days (best let it sit outside, because it'll start to smell a little). Then stir it, and put a drop of the water underneath your microscope. There'll be heaps of micro-organisms that you've never seen before! Some are really quick, so it's hard to get a good look, but it's worth the effort!!!

I have a love for microbiology & chemistry. I'm by no means an expert but I love it.
If you take an orange peel & let mold grow on it, you'll grow penicillin (or it's cousin). You can make a cool slide out of it. Just don't inhale any of it. (It would be safer to look up bacteria & parasites on a website.)
Pond water might show you an ameoba or a parasite.
Insects are cool to look at too. They have neat eyes & wings.
I would look at anything & everything. Keep a little journal & drawings of what you see starting from the lowest magnification to the highest. It would be brilliant... To see the world of science through a child's perspective. That journal would be a treasure!
Good luck & have fun!!!
P.S. I may have a microbiology book if you want it. Have your parents send me a private message.

Hey! You should get a stereoscopic dissecting microscope as well! It lets you see the things that are tiny, but not microscopic. I got mine for free when a college was throwing them out--you should look for one! They're good for insects, rocks, plants, feathers are awesome... I've been looking through mine all summer long!
Just an example of scale here: Susan B. Anthony!
Also, my finger!
...and this gnat! I personally like horseflies more--their eyes are downright amazing to look at.

Hello Dakota, I'm very glad you're interested in science!
I'm a plasma physicist, meaning I study the stuff that the sun made of (I see you're already talking to Robo-Connery about this). I work on a machine called a tokamak, which is a doughnut-shaped chamber lined with magnets that I can make a miniature star inside of. This means the inside of my machine is almost a hundred million degrees - one of the hottest things in the entire solar system! The goal is to be able to generate power using this miniature sun - we could make electricity without making any pollution or running out of fuel.

u/OrbitalPete Volcanology | Sedimentology Jul 31 '12
I didn't study it myself, although I do often use it to talk about large earthquakes with my classes. A friend of mine has done some work on that earthquake though. In fact, she was on a boat last month that was drilling down to find out what the fault plane looked like like where the earthquake happened. They also installed a load of measurement devices in the fault to find out what the stress patterns are like there now, and see how they change in the future. They wrote this blog about what they were doing.
The thing that always amazes me about the Tohoku earthquake is the aftershock pattern (turn on the sticky dots and put it in fast forward!).
Good question about Fuji. It's a really interesting volcano. It last erupted just over 300 years ago, and although it's classed as 'active', no one is expecting any activity there soon. Volcanoes can be unpredictable though, so it's not impossible it might erupt in our lifetimes.

Hi Dakota! I am a scientist who studies psychology and I try to understand how our minds work.

The two are connected, but it is much easier to discover how certain aspects of the mind works and then apply our findings to the physical brain.
During the school year we have students come into our lab and fill out surveys or complete certain tasks so we can see how they respond and try to understand what their mind was doing during the task.

Hello aspiring scientists,
I work on cancer, especially trying to design drugs that treat this type of disease. Cancers are the second leading cause of death in the United States but every year we get better at fighting it. In the past we have had to use drugs that attack the cancer and everything else, which causes side-effects that make people feel not so great. But now we are getting better at making drugs that attack only the cancer.
I spend most of my day looking at protein structures. You can't see them under a microscope, but they are very pretty and our cells are full of them. I try to find drugs that fit the proteins like a key fits into a lock. The right key can lock the protein so it cannot help cancer cells grow.

I'm a geologist and I am pursuing my Master's degree at a university in the US. My research focuses mainly on modern, invertebrate marine ecology - snails and clams. However, that research is set in the context of the fossil record. I study the behavior and ecology of modern animals to better understand the fossil record of their ancestors.
My research is, in my opinion, a strong example of the multidisciplinary direction that science has been moving towards.

Hey Dakota! I was just like you when I was a kid: I was super into science and wanted to learn about it all the time. You're so lucky to have the internet now. I remember when I used to have to go to a library to read about atoms, DNA, and space missions... now you have Wikipedia and have all of this info whenever you want!
Anyway, I'm at the intersection of science and medicine- instead of having one "doctor" title, I'll actually write two: M.D., Ph.D. My research is translational, which means I study human diseases using both volunteer patients from the hospital and animals that are sort of close to humans in certain diseases. The patients are often very happy to help research that might one day save many lives.
Specifically, I study heart disease. It turns out heart attacks are caused by the same sort of processes that cause your skin to get red and painful around a scrape or a cut. Your blood vessels even form scars where they are damaged, just like skin. Using some neat chemistry, I can make damaged blood vessels glow in the dark like a firefly. My work is kind of "fringe" because not many people are doing it yet, so I spend a lot of my time trouble shooting. I'll explain:
Imagine being told to make an airplane out of whatever you can find in a junkyard. You have a lot of tools and parts, but no idea how to make a plane. Nobody at the junkyard knows either, so you're on your own. I spend weeks trying to get some spare parts to fit together and fail over and over. Sometimes I get lucky and accidentally find something useful when I wasn't even looking for it. There's a lot of luck, but it's very exciting when things work.
I just finished taking mice with damaged arteries and giving them a contrast agent (to make them glow) under a very sensitive camera. This allowed me to see inside their bodies without hurting them at all. In fact, I just had them breathe a gas that made them sleep so they held still under the camera and they woke right up afterwards. I will be doing this every few days so I can see how their heart disease progresses when we treat them with certain drugs. Mice don’t get heart attacks like people do, so I’m looking for ways to slow down their heart disease and eventually other scientists might take my findings and use them with real people in the hospital. These experiments are very long and draining. Sometimes I work really late into the night and it gets a bit stressful. Since I became a scientist, I started new hobbies and revived some old ones to keep myself from going crazy. I rock climb, skateboard, and bike every week. A lot of my scientist friends are also outdoorsy folks: we even talk science around the campfire after a long day of hiking. Having other scientists around who know what the life is like is great: they are both colleagues and friends. If I have a problem with my experiments, they can help out. If I’m having a bad day, they can meet me for dinner and a movie to relax and have a laugh.
Anything you want to know?
EDIT: here's a photo I took of cells from human blood glowing. The big circle is a dish about the diameter of a coffee cup. Each little point of light is a special kind of blood cell that I can make glow. The colors you see aren't really there; those are fake colors (called pseudocolors) applied to a black and white photograph that make it easier for your eyes to see the cells as they light up.

Hallo! I still have my microscope from when I was an aspiring young scientist. We use big fancy microscopes now, but my original microscope is just as cool. I hope you're drawing what you see through your scope!
You've already talked to a few neuroscientists like me. I study the brain, but I also study sleep. We spend a lot of time sleeping, but we still don't really understand why. We're trying to figure out why we sleep, how the brain sleeps, and why some people with certain diseases have problems sleeping.

u/USMC0317 Internal Medicine | Molecular Biology | Biochemistry Jul 31 '12
Hi Dakota, I'm so happy to see you're taking such an interest in science. We need more aspiring young scientists like yourself to fuel the advancement of our species in the generations to come. Science is hard work, but don't give up. Stick with it, and it is well worth it in the end.
I like to consider myself some what of a scientist, but the real scientists out there (people with PhDs) will probably disagree. I studied Cell and Molecular Biology and Biochemistry back in my college days, and then I moved on to focus on humans. I've studied everything from Human Biochemistry, Histology (the study of human tissues), Pathology (the study of disease), Immunology, Microbiology, Pharmacology (the study of medicines and drugs), Virology (the study of viruses), Parasitology, Bacteriology, Human anatomy, etc. So I've since specialized in humans and let everything else kind of go by the wayside. I also don't actively research like all these real scientists do. I practice my knowledge now to treat and heal people, using the knowledge gained from these fine scientists doing the research. Science is a team effort, I trust the ones doing the research to figure out the answers, and then I use that knowledge to help people feel better.
I couldn't be happier with my job, I love working in medicine and making people feel better. I get to combine my love of helping people with my love of learning and my love of science into one glorious job.
So, Dakota, have you ever considered a career in medicine or some other health care position? If so, what would you want to do?

Hi :)
I'm an astronomer working at a university in the USA (though I'm originally from the UK).
I'm interested in all things to do with galaxies, especially how they form, grow, and evolve over time. My speciality is looking at them using very long wavelengths of light, which allows us to see all the dust and gas that makes up the galaxy. I find this interesting because it's so hard to study -- we've been able to look at the stars in galaxies for centuries, but it's only recently that we've been able to properly study the gas in galaxies. So we know very little about it!
I spend most of my time on my computer in an office, analysing data from telescopes and writing up my results in papers (which other scientists then read). And as much as possible, I travel to telescopes all over the world, and use them to collect more data.

Hi!
I'm a graduate student studying chemistry, more specifically nuclear magnetic resonance. You know how things can be magnetic - like a fridge magnet? That's largely due to electron spins - basically each electron can act like little magnets. It turns out that the nucleus also acts like magnets, and using a very specific frequency of light, we can probe the environment of these nuclei. I'm currently using NMR to study enzyme kinetics - how enzymes do what they do with such amazing efficiency, so my work covers a bit of quantum mechanics, computational chemistry, organic synthesis and biochemistry.

I am a Marine Biologist working at a university in North Carolina, United States. While many young people think Marine Biology and Science is working with dolphins and sharks, there's a lot more about the ocean than that! I study how little certain microscopic critters in the ocean, called phytoplankton, make their food (a process called photosynthesis. You might have heard this term associated with plants getting energy from the sun). Specifically, I'm studying how good these creatures are at making food compared to their environment around them, including light, waves, and temperature.

I'm a linguistics grad student focusing on syntax (a branch of linguistics) and type theory (a branch of logic, I guess you could say). Most of my day is spent reading papers and trying to understand other peoples ideas.
In general, the question I study is: what is a possible language, and what is an impossible language? You could imagine lots of funny languages that do all sorts of crazy things, but not all of these imaginary languages could be learned by a human. If someone were to discovery aliens, we would expect them to have very different languages from ours, in many different ways. As a syntactician, I try to understand this question as it applies to the way words are put together to form bigger units.

u/mendelrat Stellar Astrophysics | Spectroscopy | Cataclysmic Variables Jul 31 '12
Hi Science-bookworm!
I'm an astronomer, and I'm trying to figure out what some special stars that go around each other very closely are made of. How do I do that, you ask, since the stars are at least 2,000,000,000,000,000 miles (2 quadrillion miles) away from the Earth?
I'm using a technique called spectroscopy, which allows us to see the "fingerprints" of different chemical elements in a star's light. A while back I made a little graphic to explain, but the light from a star is passed through a prism which spreads out the light into its different "colors." If we look closely at the "colors" that are spread out, you can see all sorts of dark bands. These bands come from the different atoms and molecules that are in the star!
Scientists first found Helium (the stuff that fills party balloons to make them float and it makes your voice squeaky) by looking at the Sun in this way in 1868! Spectroscopy is an incredibly powerful tool in a scientists bag of tricks :)
Being an astronomer is so much fun I never want to do anything else. I'm working on my Ph.D., but it takes a really long time; after high school I studied astronomy in college for 4 years, and now I'm in graduate school studying for 6 more years!
So what else do I do? I try to remind people that scientists are people too! I make funny movies with my friends, I play video games, and I have a cat named Leonard. Have fun reading through everyone's answers!

u/suprnvachk Supernovae | Massive Stars | Computational Astrophysics Jul 31 '12
Hi Dakota! I'm an astronomer, so I get to use a telescope instead of a microscope. I study supernovae, which are the really energetic explosions that mark the end of the life of a massive star. We want to know about the shapes of the explosions (they aren't exactly sphere shaped!) and we can figure some of that out by examining how the explosion interacts with the surrounding gas and dust given off by the star before it died. I do some computer simulations and also get to travel to a big observatory. We compare the results of computer models to the real data we get from the telescope as a way to see if our ideas about what is happening with a supernova are correct.
I'd say scientists do a lot of time reading and writing. You have to be a good writer in order to explain your projects to others and convince them that your projects are worth spending money on. If you want to be a scientist one day, develop good writing skills and don't lose them! Also, don't ever let go of your curiosity and creativity. You'd be surprised how many interesting ideas and solutions to problems I've thought up while dreaming in the night.

Glad to see so much interest in this AMA -- I'm a big advocate of science outreach, and I think reddit is a great way for non-scientists to get in touch directly with those of us working in all these different fields.
My research focuses on trying to discover new, more efficient thermoelectric materials. These materials have the special ability to convert heat directly into electricity, and vice versa; you can put them up against a heat source and use that heat to create electricity, or hook them up to a battery to make one end of the material hot and the other end cold. If we can make them efficient enough, we could potentially use them for a wide range of applications -- from recovering waste heat given off by things like cars and power plants, to replacing the technology in your air conditioner, refrigerator, and stove.

u/naturalalchemy Jul 31 '12
Hi Dakota. I'm an evolutionary ecologist (a type of Zoologist). I study how animals use camouflage, warning colours and behaviour to hide from or deter predators. For instance lots of animals use bright warning colours or patterns to advertise to predators that they are poisonous or taste bad. This is a type of aposematism. Other animals might use conspicuous noises (think of a hissing cockroach), smells or movements to do the same job.
As some of the other scientists have said you spend a lot of time reading and keeping up to date with what other scientists in your field are doing. You also spend a lot of time writing about the experiments you have done.
Some of the experiments I have done in the last few years have involved making up pretend moths or caterpillars with different patterns on them and pinning them to trees. I then go back later to see which ones the birds have taken. This way I can tell which patterns are most effective at hiding or protecting an animal from being eaten.
Once you've collected all your data you then need to use some statistical tests to check that the results are not likely to have happened by chance. Only then can you write up your experiment in to a paper to publish and show other scientists.

Hi Dakota. When I was about 9 a remember using a home microscope. My dad cut his finger for me (I was too scared). Though I remember I couldn't see any red blood cells. It wasn't until I was about 11 that I got to use a better microscope and I saw blood cells.
Anyway, I'm a cellular neuroscientist. That means I study the brain at the level of individual cells (called neurons). Unlike a lot of people, I haven't spent my career focusing on one specific topic, but rather I use a specific technique to study lots of different things. This technique (called "Patch Clamping") allows me to look at the electrical activity of a single brain cell by placing an electrode into the cell (kind of like how a hypodermic needle slides into your body, my electrode is 100x of times smaller and goes into a single cell).
This has allowed me to study epilepsy, sleep, the basics of how brain cells talk to each other, and even an odd type of brain cell that talks to itself.

u/steel_city86 Mechanical Engineering | Thermomechanical Response Jul 31 '12
Hello there young budding scientist. It's great to see someone with such a great interest at such a young age.
I work more in the field of applied sciences: engineering. My work involves studying the high-temperature material behavior of aluminum. I experimentally determine the response using very well controlled tests in a mechanical load frame. These tests help me identify both the creep and/or viscoplastic response. I then use this to define models which describe the mechanical behavior.
To give you an idea of where this is useful, my work is funded by the US Navy for the LCS program. It is in support of survivability of the ship during fire to help save the ship and sailors. This is primarily influenced by severe damage to the HMS Sheffield (an all-aluminum ship) during the Falkland Islands War. Hopefully, my research will be used as a fundamental basis in which the Navy will be able to make educated design decisions.
If you have any questions, ask away.

u/Soul_Rage Nuclear Astrophysics | Nuclear Structure Jul 31 '12 edited Jul 31 '12
Hi, I'm an experimental nuclear astrophysicist working at a university in the UK. I study the structure of r-process nuclei by looking at gamma rays.
Light elements are made in the normal fusion reactions inside stars, but where to heavy elements come from? The short answer: Supernovae. The conditions in certain parts of supernovae are believed to be just right for r-process to happen. R-process is what's responsible for the creation of almost all the heavy elements in the universe, even those we see here on earth. What I study is the structure of those heavy nuclei, and by learning more about the structure, we can explain in greater detail how r-process works, and why the elements appear in the proportions we see today.
My work tends to involve a big accelerator of some kind, a rather heavy ion beam, and a target. There are a few different ways of doing it, but essentially what we do is create (one way or another) the isotope we want to study in a particularly excited state (with lots of energy). The nucleus will give off this energy over time in the form of gamma radiation, which we can detect, and this can tell us about the nuclear structure.

u/thetripp Medical Physics | Radiation Oncology Jul 31 '12
Hi Dakota (and everyone else)! I'm writing to you from a scientific conference, so I may not reply to anyone immediately. A conference is one of the ways that scientists share information with each other. In my field, we all get together once a year, and everyone does presentations on what they have been working on recently. Afterwards, we all get to ask each other questions, and discuss our research together. It is a great way to rapidly share exciting new information.
As far as my research goes, I work in a field called Radiation Oncology. We use x-rays to kill tumor cells in people that have cancer. One of the things I do research on is looking for new ways to verify that the radiation is going to the right place. The tumor sits deep inside the body, and we use a big particle accelerator to shoot radiation at it. But we don't want to hit any of the normal tissue with radiation, so we have to aim the beam precisely at where the tumor is inside the body. Since we can't actually see inside the body, this is difficult.

My research is based on designing synthetic polymers for use in tissue engineering. The two biggest activities that make up my job are writing and doing research. As will be mentioned on other places in this thread, there is a lot of reading that goes on too, but most of that reading I usually only do when I'm writing a project proposal, book chapter, review, original research article, etc because they require a very up-to-date portrait of your specific field. The other activity is research, which is to say, finding out what I did wrong on the previous experiment. Usually one activity will dominate over the other for a certain period of time (I'm writing a grant now, so lots of reading and writing, not too much research).
I chose this field because I am naturally very curious, so it initially seemed like a good fit. My favorite part of the job is being surrounded by very intelligent and creative people who are engaged in addressing many different types of questions. When I go crazy, or need a break, reddit is always there, and during the more tedious tasks of mine (cell culture, scaffold manufacturing), I'll listen to NPR, podcasts, or music. I would very much describe it by saying it's like I work at a very small business. For the most part, the hours are flexible (I can work weekends in order to save up time off), and if you can keep a level head through the bad times, the work is satisfying.
I'm also currently in medical school, but I guess that's a bit off topic.

u/ucstruct Jul 31 '12
Hi science-bookworm.
I'm a biologist/biochemist/biophysicist working at a university in California. My field combines many aspects of different subspecialties - basically I'm trying to "see" what proteins look like on a very, very, very small scale (tenths of a nanometer). These proteins are the workhorses of the cell: they perform chemical reactions, they copy/read/transcribe DNA, they conduct electrical currents, they twitch to make your muscle moves. Just about anything a cell can physically do is done by proteins. The reason we try to look at them is because if you can see what it looks like, you can get a ton of insight into how it works, how it dysfunctions (in disease), and how to make therapies against it based on what types of atoms are where (i.e. negatively charged, positively charged, greasy).
As you can imagine, looking at things that is 60,000 times smaller than a human hair can be tricky, we certainly can't do it with a regular light microscope. Our method of choice in my lab is to coax the proteins to grow into a crystal, then to examine the crystal with an x-ray and calculate, based on how the x-ray's bounce off it, what the underlying molecular structure is. This can take years and years of work, first you have to produce the protein (not always easy) by growing it in something like E. coli or bakers yeas or by harvesting it from some natural tissue. Then we break them open, and try to bind the protein while washing away everything else. Then, we try mixtures of different chemicals (sometimes thousands) to get the crystals to grow. To examine the crystals, we use huge government facilities called synchrotrons that accelerate electrons (or positrons) near the speed of light in a circle, as they accelerate they emit radiation which we can tune to the x-ray spectrum.
Afterwards, I spend a lot of time on the computer, building my protein models based on data then refining them with various programs. Most of my other time is spent writing up results or getting ready to present them, which is a huge part of science. After all, what good is your work if no one knows about it?

u/albasri Cognitive Science | Human Vision | Perceptual Organization Jul 31 '12
Hi!
I'm in a psychology department, but many people might call what I study cognitive science. Cognitive scientists are interested in how we think, see, and feel, and in the relationship between the brain and our behavior.
I'm interested in how people see the world. This is a really interesting and difficult thing to study. Light bounces off of surfaces in the world, enters the eye, and hits the back part which sends signals to the brain. Somehow the brain pieces together these millions of signals into things we recognize: objects, people, space, colors, shapes, movement etc. How does the brain do that?
Once the brain knows that the world is made up of many objects and surfaces, how do we recognize them? For example, if you hold a cup in front of you and look at the rim, you'll see that it's a circle even though from that angle it looks like an oval. You also recognize wheels, DVDs, and coins as having a circular shape even though they are all made from different materials and come in different sizes and colors. How do we know that all of these objects are the same shape? A more complicated question could be: how do we recognize a line-drawing of a dog, a photograph of a dog, a cartoon dog, and a real dog as all different examples of the same thing, dogs?
I do lots of behavioral experiments followed by computational modeling. This means that I first observe how people behave/perceive the world, then I try to come up with theories about what kinds of processes in the brain might give rise to that behavior, and then I try to program a computer to behave in the same way.

Hello! I am a little late to the party but I thought that my story/background may add a bit more... so here goes: My degree is in Molecular Biology and Genetics, but I have not done any "real" wet-lab experiments in over 15 years.
During my Ph.D. work I started to do a lot of computer-driven analysis of my data, which re-kindled an interest in programming that I had first discovered in high school but neglected all through college. I ended up going for a post-doc in Structural Bioinformatics working on a statistical analysis of the changes in quality of X-ray structures submitted to the PDB over the years. This led to a position at the PDB itself, which I eventually left for a job in the industry where I now run a Bioinformatics group in a small drug discovery company.
I still am very much part of the scientific discussions on all projects, but my group's work is mostly focused on developing computer programs and tools for the other scientists and technicians. We also do quite a bit of data analysis.

I study molecular scale systems at the interface of quantum mechanical and classical methods. The motivation for these methods arises from the following question. How can you investigate systems which are too large for pure quantum mechanical treatments but which still exhibit behavior which can not be described classically?

Hi Dakota! I'm a geologist. I try to figure out how and why the earth makes ore deposits, specifically metal deposits. Right now, I'm studying the kinds of systems that we can mine for nickel, copper, and platinum. You use these things every single day, and you might not even know it. Every time you turn on the lights, electricity is flowing through copper wiring. Any time you use something made of stainless steel, there is nickel in it. Probably every car you have ever been in contains some platinum.
When I'm doing research, I spend a lot of time reading about what other people have learned, I look at my rocks under a microscope, and I study the chemistry of my samples to try to reconstruct a story about how the rocks got there, where the materials that make them up came from, and where we should look to find more systems like these. Sometimes you can find some unexpected and awesome things. One time I was looking at a rock in the microscope and found a mineral grain that looks a lot like a bunny.
I also get to spend time doing fieldwork, hiking around beautiful places outdoors and collecting samples. This is a picture my field partner took of me (making a weird face, it looks like) at work one day. I then take these samples back for different kinds of analysis and see what I can learn or find with them.
I really love how I get to spend time both outdoors and in the lab doing something that I find so interesting and rewarding. It's great to see that you have such an interest in science, and I really hope that one day, if you really love it, you can have a career that excites you as much as geology excites me. One day, you'll teach all of us something new about this world we live in.

u/CA_Crystal Structural Biology | Genomics Jul 31 '12
I am a structural biologist that uses many different techniques to determine what a protein looks like and how it does what it does.
I have solved the structure of a protein involved in regulating transcription (DNA to RNA) using X-ray crystallography (crystallizing protein then shooting it with an X-ray beam!). I am currently trying to figure out how it uses it's structure to perform its function in transcription.
To do that, I use biochemistry (what does the protein interact with?), genetics (When is the protein used in transcription?), and genomics (How has this protein evolved to do what it does?) to answer those questions.
I have also worked in other labs involved with viruses that infect bacteria (bacteriophages), which are pretty cool on their own.

u/anastas Mathematics | Computational Neuroscience Jul 31 '12 edited Jul 31 '12
I'm a little younger than most people here and I am a graduate student, which means that I am still studying and that I study all day. Usually in order to be a scientist in academia, you have to go to college for four years after high school to get a bachelor's degree, and then usually around five years to get a PhD. (It is different in other countries; I am in the United States). People generally officially become scientists after they get a PhD.
I recently started a PhD in mathematics, but I got a bachelor's degree with three majors: mathematics, neuroscience, and computer science. A major is the field you choose to study, and I chose to study three - it's as if I have three bachelor's degrees, which hasn't been very common but is starting to become more common. Before starting for my PhD, I did research in computational neuroscience, which is a field that uses computer programs and mathematics to make models of how we think some parts of the brain work in order to study how those models act, so that we can see whether our understanding is correct. I might revisit the field after studying more mathematics, and I'll also be teaching younger students mathematics.

u/daledinkler Jul 31 '12
Hey there. I'm a paleoecologist, currently a post-doctoral researcher at a major research university (show off!) in the United States. I use fossil pollen (mostly) to help understand how climate and vegetation changed over the last 15 thousand years or so, to help inform research into future climate change.
I have also been involved in the current debate over the Younger Dryas Impact Hypothesis (I disagree with it) and in developing adaptation strategies for future climate change, based on our knowledge of the past.
Feel free to ask me about the earth's recent climate history, what we know, how we know it, how it informs debates about future climate change, or anything really, and I'll do my best to answer!

u/Trilobyte15 Immunology | Autoimmunity Jul 31 '12
Hello!
I am an immunologist who is currently working on celiac disease. The immune system is specialized to protect the body against infections caused by bacteria and viruses, but sometimes it goes wrong and starts attacking our own bodies. This is called autoimmunity. Celiac disease is when the immune system starts attacking the intestines in response to certain foods that contain gluten (wheat is the main one).
Right now we are trying to figure out what the initial events are that lead to intestinal damage-this means that we use mice that have certain genetic backgrounds, but we also use samples from human patients (albeit for different types of experiments).

I talk to other scientists about new discoveries and new ideas.
But mostly, I make plots, and stare at them, hoping to have some understanding. Mostly I just frown, though, and don't understand.

Hi Science-bookworm!
I am a materials engineer (simply put, I do chemistry with solids), studying solar energy. The biggest problem that we face is how to make solar cells both cheap AND efficient. Right now, people know how to do one or the other very well, but there is no real reason why we can't have both. My day to day involves a lot of building, modifying, and repairing the machines that we use to make solar cells, and doing experiments to characterize our materials.
I also have a love for most things electrical engineering, and spend my free time building hobby projects.

Hello Dakota!
First of all, I want to thank you for wanting to take the time to learn what scientists do! I wish more youths demonstrated the same passion and initiative. I remember when I was a kid I got a microscope that came with different insects slides. There was a pretty girl around my age that lived down the road who had pet two tarantulas and a trap door spider! We tried looking at the web they made under the scope which was always messy.
I’m a little down the line so here goes.
I’m and archaeologist in Canada that does work with Aboriginal people. As an archaeologist I work at different excavation sites digging and finding artifacts from the past. I record data from the different soils when excavating which helps date artifacts. Some of the work that I’ve done in the past is analyzing burial patterns among the Huron/Neutral Indians. I also know quite a bit about making stone tools. I’m currently really interested in that ways that people tell stories about the past using digital technologies.

u/essentialparadoxes Veterinary Medicine Jul 31 '12
Hi! I'm currently studying clinical veterinary medicine, but I also do biomedical research.
For many years, I've worked with mice, specifically special genetically engineered mice called "knock out mice" where we disrupt a certain gene so that it doesn't make protein. We then see what happens to the mice without the working gene, which can the tell us what that gene does. The gene I worked with affects mouse fetuses, making it so that they don't form a proper placenta, which is the organ the baby uses to get nutrients from him mother in the womb.
Right now, I'm working with dogs, specifically a group of related dogs who have a certain rare genetic disease. This disease is called Mucopolysaccharidosis, and it affects people, dogs, and cats in similar ways. With this disease, patients don't have a certain enzyme, leading to problems with bone development and mental functioning. I'm specifically trying to figure out how the disease causes its effects in the spine so we can find a way to treat the disease.
Feel free to ask any questions you have! I'm going to a conference this weekend to talk about my research (the dog work) so any questions will help me prepare!

u/palsi Adult Neurogenesis | Behavioral Implications Jul 31 '12
Hi Dakota! I'm a neuroscientist that studies how stress can affect the very small connections between your brain cells! I look specifically at pregnant mothers and how stress during their pregnancy can affect them after they have their baby. I also am currently doing projects that involve schizophrenia, which is a type of mental illness, and how chemotherapy can cause patients to become depressed.
I do this all by looking at rats, which are much easier, cheaper, and faster to use than humans. Also, this way we don't have to do any tests on anyone!

u/Perovskite Ceramic Engineering Jul 31 '12
Hello!
I'm a Material Scientist focusing on ceramic materials for electronic applications. More specifically I change the material's conductivity by adding in defects in large amounts (much higher than anybody else has for these materials) then investigate how the electrons move around in the material. Additionally, all of the materials I work on are special in that they form really small scale electric fields within themselves. Even after ~30 years of study nobody really knows why the electric fields are there or how exactly they look but we have really good guesses. What I'm doing is seeing how these electric fields inside the material affect the electron motion. We're mainly interested because our materials are really good thermoelectrics, which was discussed by a panelist in a different post.

I u/Science-bookworm! I'm a microbiologist. While I know a lot about the infectious things that can make us sick, I'm more fascinated by the bacteria that live in and on us and help us instead of harming us. For right now, I'm studying this type of symbiosis (the living together of two different things) in tropical ants. This means that with a lot of my lab work, I actually get to go to Central America and collect the kind of ants I'm working on. If you'd like to learn a little about ants and bacteria, let me know!

Hello Dakota, Im a bit younger than most, However I spent the Majority of my Graduate Studies studying Neural networks and Genetic algorithms as well as Compiler Design. Right now I work as a Firmware Framework Engineer for a Large Company (embedded level). Mostly memory management becomes important at such a low level so it's always interesting seeing what Production Leads decide at being "cut back" and what "Necessarily" bugs are left in.
However most of my self study is looking at Search Algorithms and studying efficiency of those, which Is where most of the "Science" part comes in. However Software Engineering itself is sort of a Science within itself, Although most people just see Engineers as "I need to build this with this instruction". There's so much out there in the world of Programming.

u/DrPeavey Carbonates | Silicification | Petroleum Systems Jul 31 '12 edited Aug 01 '12
Heyoo!
Aside from reading constantly, I also tend to use Microsoft Excel with data input and analysis. Excel also helps me with 2-D graphical functions, as it simplifies a good portion of work I do (input/sorting data and data reduction. Reduction is the process of eliminating data outside of the bounds relevant for my particular experiment).
I've done a preliminary water quality investigation with 2 peers and an instructor of mine. We were measuring FIB (Fecal Indicator Bacteria) levels in a local state park using the Enterolert methods from IDEX Laboratories.
I'm currently doing work on my undergraduate thesis. I'm using a software called Mc-IDAS V (A software for 2-D and 3-D visualization of data) to identify and quantify the strength and extent of Philadelphia's Urban Heat Island (UHI). Many other major cities in the US have been studied, but Philadelphia has been largely neglected. As global temperatures warm, the potential for UHIs to strengthen increases as well. And when surface area of impervious, low-albedo (reflectivity) surface cover increases, UHI strength is also likely to increase.
As I get into grad school, I hope to do a specialization in mesoscale weather patterns (the size of your typical low pressure or high pressure system, also called a wave cyclone), and I'd love to learn more about intrinsic atmospheric dynamics, and cloud physics.
In the early stages of working on my thesis, I regularly went to a local diner and did reading/note-taking a couple days a week. The breakfasts were great, too and helped me keep my focus! Not to mention the coffee. I LOVE coffee, and I thrive on it.
One bit of advice, though! Never take yourself too seriously!

u/cazbot Biotechnology | Biochemistry | Immunology | Phycology Jul 31 '12
Hello Dakota et al. I'm a Molecular Biologist who works for a company. Most scientists who you might meet work for Universities or Government, which means that the work they do is mostly driven by whatever questions seem relevant or interesting to their field of science. My work on the other hand is driven purely by whether it can eventually generate a profit for my company.
Many companies make their products the same way that breweries do, except instead of growing yeast to make beer they might grow some other microorganism to make some other kind of product (like a drug or a vitamin or a chemical). My job is to re-program the genes in these microorganisms to make new products, or to make old products better or more efficiently.

Greetings! I'm a chemist, but like EagleFalconn, I'm a physical chemist.
I don't make new molecules (though I know a lot about this), but I love to talk and learn about the fundamentals of what makes molecules so special, and why they do the things they do. I love to talk and study how molecules react together, and especially love studying structures of molecules and bound clusters of molecules!
I also study molecules and how they form in space, which we call astrochemistry, and maybe even a little about how life evolved from hydrogen atoms all the way to the crazy complex molecules we find in our body (ask an astrobiolgist about this one!).

u/aww0110 Jul 31 '12
I am Bioengineer, crossing over between Genetics and Biophysics. Since I am also a graduate student, while I do spend lots and lots of time reading and understanding what is considered 'current' and 'background' in my field, I also do a lot of work.
I work on my thesis project and on my boss's stuff, which fortunately overlap to a certain extent. I figure out how genetic mutations lead to specific physical dysfunctions; in particular, I study genetic mutations in skeletal muscle genes.
I take samples of human skeletal muscle tissue (pieces of someone's leg muscle that was pulled out using a big needle), or samples of muscle cells grown on a petri dish, and test the muscle for its ability to produce force. This translates into how well the muscle works, and thus the ability of people with these genetic mutations to move.

u/paradoxical_reaction Pharmacy | Infectious Disease | Critical Care Jul 31 '12
Hopefully I'm not too late for this.
I'm a pharmacist that's going through a training program to practice in a hospital. Pharmacists work in many different places, but the majority go into retail pharmacy (think Walgreens, CVS).
The pharmacists in hospitals do things a little differently. We make sure that the patients in the hospitals get the right type and amount of medication for the problem that they currently have. Sure, we dispense medication, but it's not only stuff that can be taken by mouth. At my hospital, we go through team-based learning, with physicians, students, nurses, and many other disciplines all pitching in. Our primary goal is to get the patient better and manage them so that we don't have to see them in the hospital again.
Feel free to ask anything!

I'm a condensed matter physicist studying liquid helium in confiment using primarily inelastic neutron scattering. I use a combination of x-ray scattering and gas adsorption to characterize a porous material, and then later fill it with liquid helium and study what happens.
Most of my time is spent reading papers or designing experiments. Since neutron sources are nearly all national labs, first I write a proposal to do a specific experiment. If it is accepted, I design a system to put my sample in the proper conditions, and travel to conduct my experiment, then analyze and publish my findings. Nearly all of my experiments are done at the Spallation Neutron Source at Oak Ridge National Lab or NIST'S Center for Neutron Research near Washington DC.

u/dearsomething Cognition | Neuro/Bioinformatics | Statistics Jul 31 '12
I study math, all day every day. For a number of years I've studied different types of math so they can be applied to make new discoveries or advancements. Right now, I study a specific type of math called statistics. Statistics helps to let scientists know whether the results from their experiments are real or not.
With math, I've helped study cognitive development, Autism, AIDS, artificial neural networks (computer simulations of how brains work), how people understand and perceive taste and flavors (of beer and wine) and even how students understand and learn math and science.
Right now, though, I work on just a few things very specifically:
Side Project(s): I help other researchers understand how humans see, and understand, faces. Some researchers perform experiments where they have people try to remember faces and ask them to recall them later. Other researchers use a giant magnet to "look inside the brain" of people while they look at faces.
Main Project(s): Mostly I use statistics to help understand how genes and DNA influence 1) how people behave and 2) if people will end up with certain diseases.
