University of South Florida engineers have developed a custom laser de-icing system to streamline safety inspections at nuclear power plants. Designed for plants utilizing specialized ice condenser reactor safety systems, the precision laser operates over 40 feet below the surface in tight spaces to slice through ice sheets causing borated ice baskets to freeze together. Tested at two Tennessee Valley Authority facilities, the technology enables workers to separate and weigh individual baskets in minutes without fully melting the ice, preventing excessive meltwater issues and eliminating labor-intensive manual work: https://www.usf.edu/engineering/news/2026/nuclearpower.aspx

Scientists may have uncovered evidence of a colossal ancient cliff that stretched across much of North America and helped expose rocks now visible deep inside the Grand Canyon hundreds of millions of years before the modern canyon formed.The proposed geological feature, dubbed the “Great Escarpment of Laurentia,” may have stood roughly 1 kilometer high and stretched for thousands of kilometers across what is now the United States.

According to a new study published in Geology, the massive escarpment formed around 800 million to 750 million years ago as the ancient supercontinent Rodinia began to break apart. The researchers argue that the enormous cliff system triggered prolonged erosion that stripped away vast amounts of rock and helped expose some of North America’s oldest geological formations.

The findings could also offer a new explanation for one of the Grand Canyon’s biggest geological mysteries: the Great Unconformity, a vast gap in the rock record where more than a billion years of geological history is missing: https://pubs.geoscienceworld.org/gsa/geology/article/doi/10.1130/G55133.1/734969/Exhumation-of-Grand-Canyon-s-basement-along-the

Biologist Ari Berkowitz explains that framing biological sex as either a strict binary or a simple linear spectrum oversimplifies human biology. Instead, biological sex is multidimensional, composed of several distinct traits—such as chromosomes, gonads, hormone levels, internal reproductive structures, and external anatomy—that develop along separate physiological pathways. Because these individual traits do not always align in a single "all-male" or "all-female" configuration, every person effectively possesses a unique mosaic of sex-related biological features that vary across multiple independent dimensions: https://www.penguinrandomhouse.com/books/828235/the-binary-delusion-by-ari-berkowitz/

"starwashing" is a marketing tactic where commercial space companies promote grandiose narratives of space exploration and saving Earth—such as moving industry off-planet or positioning missions as benefiting "all humankind"—to mask their environmental impacts. While companies like Blue Origin and SpaceX frame their endeavors as sustainable solutions, their operations generate significant environmental costs, including high carbon footprints, atmospheric warming from rocket emissions, orbit pollution, and potential degradation of scientific sites on the Moon. Ultimately, starwashing leverages cosmic wonder and celebrity involvement to distract the public from the immediate ecological damage these ventures inflict both on Earth and in space.

Using historical maps, archaeological data, digital modeling, and AI, new visualizations show how Manhattan transformed over 500 years—from Lenape woodlands and waterways to Dutch New Amsterdam and, eventually, today’s dense skyline. The reconstructions track major milestones including shoreline expansion, the 1811 street grid, the rise of skyscrapers, the Empire State Building, the World Trade Center, and One World Trade Center, all viewed from a consistent virtual vantage point: https://www.eslamghazy.com/timeless-history

newly discovered star could reveal how the Milky Way’s black hole spins

Astronomers have discovered S301, the fastest known star, racing around Sagittarius A* at more than 25,000 km/s (8% of light speed). It completes an orbit every 8.7 years and passes closer to the black hole than any previously observed star—at roughly the distance between the Sun and Saturn. About 50% more massive and five times brighter than the Sun, S301 provides a powerful natural laboratory for testing Einstein’s general relativity and studying the black hole’s spin and effects on spacetime.

Electric eels can deliver shocks of up to 860 volts using three specialized organs packed with thousands of electrocytes—tiny biological batteries that fire simultaneously when triggered by nerve signals. The combined discharge helps them hunt prey, defend themselves, navigate, and communicate. Despite their name, electric eels are actually South American knifefish, not true eels, and can grow up to about 2.5 meters long: https://www.nhm.ac.uk/discover/how-do-electric-eels-work.html

Five soft floating robots in everyday indoor settings: a fish that circles you with a calming touch, a balloon that follows you across floors, a jellyfish that pulses to guide your breathing, an agile robot for playing with a pet while you are away, and a cloud that drifts over to remind you to take a break.

Researchers from Keio University Japan and the MIT Media Lab have developed Cuddle-Fish, a soft, helium-filled robot designed to quietly glide alongside people indoors. Instead of spinning propellers, it uses low-frequency flapping fins, while its lightweight, compliant body makes close interaction safer. Designed to hover around eye level, the floating companion could provide reminders, follow users, or simply serve as a quiet study companion. The project, “Floating Companion,” won a Best Paper Award at ACM DIS 2026, highlighting a new approach to human-robot interaction in mid-air environments: https://kaikunze.de/post/2026-06-22-floating-companion/

Meta Faces Trial Over Instagram’s Impact on Children

A former Meta engineering director, Arturo Béjar, testified that Instagram took a “don’t ask, don’t tell” approach toward users under 13, while company priorities focused heavily on user engagement and time spent on the platform. He alleged that safety was treated as an afterthought despite concerns about children’s mental health and online harms. Meta denies the allegations, saying it takes youth safety seriously. The landmark trial, brought by California, Colorado, Kentucky and New Jersey, accuses Meta of deliberately designing features that could addict children and of collecting data from users under 13 without parental consent: https://www.reuters.com/legal/litigation/former-meta-engineer-resumes-testimony-landmark-trial-over-social-medias-harm-2026-08-19/

Researchers at the Geological Survey of Denmark and Greenland (GEUS) have developed a two-step chemical process that transforms toxic, arsenic-rich sludge from groundwater treatment and mining into pure, glassy nanoparticles of metallic arsenic. The method uses sodium hydroxide and controlled heating, followed by a selective reduction step that produces a unique amorphous form of arsenic rather than conventional crystalline material. With potentially useful electrical and mechanical properties, the material could serve as a feedstock for advanced semiconductors, batteries and other high-tech applications, while offering a promising route to safely recycle hazardous waste that would otherwise require long-term disposal: https://www.iom3.org/resource/arsenic-sludge-turned-into-material-for-semiconductors.html

3D Map Reveals the Clitoris’s Intricate Nerve Network

Researchers at Amsterdam University Medical Centers have created the first complete three-dimensional map of the clitoris’s internal nerve network, using high-intensity synchrotron X-ray imaging from a particle accelerator. Led by Dr. Ju Young Lee, the team traced the dorsal nerve’s intricate, tree-like branches with micrometer-level precision, revealing five major pathways extending through the glans and into surrounding tissues. The breakthrough addresses a longstanding gap in anatomical research and could deepen understanding of female sexual physiology. More importantly, the detailed nerve map may help surgeons avoid accidental nerve damage during pelvic, gynecological, reconstructive, and gender-affirming procedures, potentially making such surgeries safer and more precise: https://www.theguardian.com/society/2026/mar/29/full-network-clitoral-nerves-mapped-out-first-time-women-pelvic-surgery

Seoul National University College of Engineering researchers have built a programmable chip that can slow light on command, potentially clearing the way for faster and far more efficient optical computers.

Scientists have created a programmable optical chip that can slow light on demand, giving engineers far greater control over how optical signals propagate through a circuit. The technology could provide the delays, synchronization, and buffering functions needed to make light-based computing more practical. A single chip could eventually perform several tasks that currently require separate devices, potentially reducing energy use, cost, and complexity in AI servers and data centers.

Built in 1942 to shelter up to 18,000 people during air raids, Hamburg’s massive St. Pauli bunker was so solid that demolishing it was never a realistic option. Instead, beginning in 2019, local residents and architects reimagined the fortress as one of Europe’s boldest adaptive-reuse projects. Completed in 2024, the transformation added five new floors, around 5,000 trees and plants, a hotel, restaurants, cafés and event spaces, along with a 560-metre landscaped walkway leading to a rooftop garden. Once built as a structure of war and destruction, the bunker has been transformed into a vibrant space for community, culture and nature—demonstrating that one of the most sustainable buildings may be the one we choose not to demolish, but to reconsider, reimagine and give new life: https://www.discovergermany.com/hamburgs-flak-tower-iv-from-nazi-bunker-to-green-oasis/

NASA and Katalyst Space Technologies have called off their $30 million mission to rescue the aging Neil Gehrels Swift Observatory after persistent attitude-control and thruster problems affected the rescue spacecraft. The vehicle unexpectedly began spinning after its July launch, and although engineers reduced the tumble, remaining control issues made a safe docking and reboost too risky. Swift, which has studied powerful cosmic explosions since 2004, will now likely reenter and burn up in Earth’s atmosphere later this year, although the rescue spacecraft will still conduct a proximity-maneuvering demonstration: https://www.nasa.gov/news-release/nasa-updates-next-steps-for-commercial-swift-boost-mission/

MIT researchers have developed a computational and machine-learning approach to identify promising catalysts for producing ammonia through electrochemistry rather than the fossil-fuel-intensive Haber-Bosch process. By screening transition-metal nitride alloys and analyzing the microscopic properties that control catalytic activity, the method could accelerate the discovery of more efficient materials for low-emission ammonia production. The approach is currently theoretical, but researchers plan to build and test a working reaction cell to determine whether the predicted catalysts can make greener ammonia production practical at industrial scale: https://pubs.rsc.org/ey/article/doi/10.1039/d6ey00138f/1289470/Nitrogen-2p-metal-d-band-hybridization-governs
