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.
The decisive penalty kick in a final, match point in tennis or the last attempt in a competition: When a lot is at stake, even a well-practiced performance can suddenly break down. Yet pressure does not necessarily impair performance. Some people perform at their best precisely in the moments that matter most. Existing accounts can only partly explain why.
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.
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.
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.
In 2023, professor Damian Helbling was getting a lot of calls and emails from local residents. The Environmental Protection Agency (EPA) had just announced regulations to limit per- and polyfluoroalkyl substances (PFAS)—some of which have been linked to cancers and other negative health effects—in drinking water. Ithacans and others in the region wanted to know about levels in the ponds, lakes, streams and creeks in their proverbial backyards.
For more than 20 years, Canada's Species at Risk Act (SARA) has protected wildlife that are at risk of being lost from Canadian lands and waters. Once a species is listed as extirpated, endangered or threatened under the act, it becomes illegal to kill, harm or capture it or damage its residences. Its critical habitat must also be protected, at least on federal land.
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.
Scientists have learned a lot about what happens to the human body as we age. But there's still much to learn about how other species age, including dogs. Even carrying extra weight could affect a dog's cognitive health. Alexandra Genualdi, a student at Oklahoma State University who presented her research in September at the American Physiological Society's 2026 Comparative Physiology conference in Orlando, talks about her efforts to learn more.
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, although the benefits may diminish when the system becomes too disrupted.
