A nationwide search for giant crayfish uncovered a record-breaking Tennessee specimen and a surprising mystery about how big these freshwater creatures can grow. Scientists found that North American crayfish seem to hit a biological size limit, possibly because of their muscles or protective shells.

Scientists investigating Nazi Germany's secret nuclear program have uncovered evidence that its final experimental reactor was nowhere near as close to working as previously claimed. Analysis of surviving uranium cubes and wartime documents reveals that Germany lacked the enormous quantities of uranium and heavy water needed to make its reactor operational.

Antarctic sea ice reached its third-lowest winter maximum in 2026, extending a remarkable decline that began after years of record-breaking growth. Scientists are investigating whether the dramatic reversal signals a long-term shift in Antarctica's frozen landscape.

As Hurricane Simon unleashed destructive winds and flooding along Mexico’s coast, NASA satellites captured an extraordinary sight: massive atmospheric waves rippling high above the storm. The rare images reveal how powerful hurricanes can disturb the upper atmosphere, creating patterns that are usually invisible from space.

Scientists have discovered how to turn a protein that normally fuels cancer growth into a weapon against it. By activating PPARD in immune cells, researchers made them better at burning fat and attacking tumors, slowing or stopping cancer growth in laboratory experiments. The approach showed promise against colorectal, breast, and ovarian cancers, as well as melanoma.

USC scientists have discovered a way to create a potentially renewable supply of genetically engineered immune cells that can attack cancer and strengthen the body's natural defenses. By growing and modifying immature immune cells rather than mature ones, researchers developed a system that can continuously produce tumor-fighting cells inside the body.

Scientists have uncovered a hidden biological mechanism that helps explain how exercise can reverse some of the damage caused by muscle aging. The key is a gene called DEAF1, which becomes overactive with age and interferes with the muscles’ ability to clear damaged proteins and repair themselves. Exercise can help restore this balance, allowing older muscles to rebuild and regain strength, altho…

Scientists discovered that atomic steps just one atom high can guide quantum vortices through superconductors, making them move more than 1,000 times more easily in one direction than another. This remarkable control over quantum motion could lead to a new generation of ultra-efficient superconducting electronics.

Yale scientists have uncovered how the stress hormone cortisol helps the brain turn emotional experiences into stronger, longer-lasting memories. The discovery reveals that stress can reshape communication between brain networks involved in emotion and memory, potentially explaining why certain moments are so difficult to forget.

Scientists have discovered a remarkable “Pac-Man enzyme” that helps bacteria devour certain types of plastic and may offer new hope in the fight against plastic pollution. Researchers found that several biodegradable plastics completely broke down in soil within about a year, while conventional plastic remained largely unchanged.

Scientists have discovered that black holes of vastly different sizes appear to launch powerful jets according to the same universal rule. The breakthrough could explain why some black holes suddenly erupt years after devouring a star and help astronomers predict when these spectacular outbursts will happen.

Arctic sea ice is shrinking in both winter and summer, with satellite records revealing that the region's remaining ice is becoming thinner, younger, and more vulnerable to melting. Despite a recent slowdown in summer losses, scientists warn that the Arctic could experience a nearly ice-free summer before 2050.

Even under general anesthesia, the human brain can analyze language, recognize different types of words, and predict what comes next in a story, according to a surprising discovery by Baylor researchers. The findings challenge our understanding of consciousness and suggest that the unconscious brain is far more capable than scientists previously realized.

Eating late at night could be putting your liver at risk, according to a large study led by Oregon Health & Science University. Researchers analyzed data from nearly 200,000 people and found that those who regularly ate after dinner or around bedtime had a 20% to 30% higher risk of liver disease, including fatty liver disease and cirrhosis.

Scientists have discovered a potential new weapon against a devastating fungus that threatens rice, wheat, and barley worldwide. By engineering a special type of plant immune receptor, researchers created defenses capable of recognizing multiple fungal threats at once. The breakthrough could eventually lead to crops with powerful, long-lasting disease resistance, helping protect a global food sup…
