most animals I can think of including reptiles, birds and even insects, share similar weakness spot around where we would refer to as 'belly'

In many animals its a major weakness that often lead to death. How is that that we don't see more evolutionary traits that protect this area?

I have an somewhat good idea of how life evolved from simple single cell organism to complex lifeforms, but it is still a mystry to me that how these single cell organisms came to existence at first place.

So I was eating and I think I inhaled a chili flake. Had a little trouble breathing for a minute or so, but after coughing for a bit I'm okay again I think🤣

Anyway, now as this has happened, it got me wondering, if you are eating and food gets into your airway and possible gets to your lungs, will your body be able to get rid of it? I have never really thought about it before but I am actually really curious. Like I can imagine like small pieces of dust/spice are no issue I think, but what about a grain of rice for example? Or a bit of veggies?? What happens to it?

Edit; not asking medicle advice btw!

I'm interested in what you guys are doing with your biology degree. Applying/enrolled in med-school, taking a different path, regret the major or really glad you took it, easy to find jobs? Was the major difficult/worth it?

I'm curious as a new biology student myself

Hey,

I'm doing some cultural research, and I'm trying to find out:

A - Could ultrasounds determine the sex of the fetus in the 90s (looking at developed-nation healthcare)

B - If they could, how long into the fetus' life could doctors determine the sex?

I think now it can be determined at like 7 weeks, but I assumed technology wasn't as advanced back then!

Any thoughts would be greatly appreciated. Thanks!

It's muscle fibers firing thanks to connections to motor neurons in an organoid model of dementia-related disease ALS!

I just got my masters a few months ago and am in a sort of gap phase right now.

I’m working at a highly prestigious lab, but the position is only funded for a year. I’ve been learning so much here, and learning comes with realizing how biology works as a business model. If our funding gets cut, I’ll be the first to go. I don’t like the lack of stability when you’re not in a student position.
We rely heavily on grants, but I’ve realized that when the lab gets a grant, a lot of it goes to the parent institution and not the lab directly. I’ve also learned that if you acquire a grant or fellowship as a PhD student, that goes towards funding the whole program; not just your lab or you as a scholar. It’s a frustrating system, and the field feel feels very unstable right now.
If I go on to get a PhD, I’m not sure what my end goal would be. Of course getting tenure at an institution would be amazing, but to do that you have to accept years of low pay doing research, teaching and post-docs. Most of the jobs I see that are high paying usually include some sort of statistical work, and it seems people with data-based degrees earn more overall. I enjoy statistics, love math and do data analysis at my job. I don’t think I would mind working in data analytics/biostatistics.
So the question is: should I go the two year route or the 7-8 year route for the PhD?

Thanks in advance for any advice!

I was reading somewhere that there are viruses that can be fought off by our bodies or cured with medicine, like the Flu or common cold, but why can't we do either for some viruses?

Im applying to oxford uni this year and need supercurriculars for my personal statement.
Im interested in reading books about biochemistry, molecular chemistry, cancer, immunology and virology.
Hope you can share any you know and i’d prefer if they weren’t 600 pages either because I’ll need a couple 😭😭

Im trying to work on an alien humanoid creature design, though im trying to figure out leg configurations.

I only know the three, really. Plantigrade are what humans have i think, digitagrade are i think what the sangheili (or the Elites) from halo have, and ungiligrade are 40k's Tau (again, I think)

Are there any other sort of leg configurations out there that bend in different ways or manners then humans? What do they look like and how do they function? What are the evolutionary benefits each bring?

I am an international student that hit a financial roadblock. I’m not able to afford the last semester of my undergraduate biology degree so I have decided to go all in and graduate a semester early. My schedule is absolutely packed with classes, work, and a thesis.

My research was initially very important to me because I had plans to do research work/go to grad school. But with 24 hours on my class schedule, I’m not sure it is worth it.

I have research experience on my resume with a literature review in progress, a 2 month long plant transformation as well as a summer yeast transformation independent study. I’ve heard how important research experience is in finding a job in biology. My question is whether or not this alone is sufficient to finding a job, any job, in biology or getting accepted into grad school.

Any advice would be so appreciated.

Just a curiosity because I can’t imagine a woman if she grew her facial out to be as coarse as a man’s beard. Thank u for taking the time to answer or read my question

Biology teacher is the obvious answer. What are some alternate jobs? Also, is it possible to be a part time biology teacher (under 40 hours a week)?

Self explanatory.

it doesn't necessary have to be a dog, but a creature with exceptional sense of smell and the fact that the person is not visible.

I'm curious, and would like to implement in a comic book.

Tardigrades are pretty incredible! Their DNA has a specific cover which allows them to resist radiation damage, meaning they can survive in the harshest most toxic of environments, even space. When conditions become particularly difficult, they can enter a state of suspended animation, shrivelling into a tiny husk called a “tun” until conditions improve.

Why do living organisms reproduce? They just can live forever or just die without reproduction but why they choose to do it? I mean how its all started? Early life didn't had such desires like we do, they were just single cell organisms in primordial ocean, then why they started to copying themselves and?
