Deep beneath Japan’s mostly submerged Kikai caldera, scientists have discovered a vast magma reservoir that appears to be filling again. The volcano produced the largest eruption of the Holocene 7,300 years ago, and seismic surveys now show that fresh magma has likely entered the same underground system responsible for that catastrophe.
A weakening Atlantic current could supercharge California’s atmospheric rivers while leaving Greenland with fewer snow-producing storms. The changes could raise flood risks, strain infrastructure, and reshape water supplies far beyond the Atlantic.
Researchers found that insulin-producing cells depend on a team of helper proteins to keep insulin production on track. When one key partner was missing, damaged proteins built up and the cells made less insulin. Strengthening this system could offer a new way to protect the pancreas as diabetes progresses.
A new analysis has precisely dated paintings in France’s Font-de-Gaume cave for the first time. Scientists discovered charcoal inside black pigments once thought to contain only minerals, allowing them to use radiocarbon dating. The results show that a bison was painted about 13,000 years ago, while sections of a mask-like figure were added during several widely separated periods.
A healthy lifestyle can prevent type 2 diabetes for many people, but new research suggests that weight loss alone may not be enough for one particularly vulnerable group. Even after losing about 8% of their body weight and keeping it off for years, people in a high-risk category known as cluster 5 continued to experience rising blood sugar, weakening insulin production, and a strong risk of developing diabetes.
NASA’s Psyche spacecraft aced its Mars flyby, using the planet’s gravity to speed toward its 2029 encounter with a metal-rich asteroid. The spacecraft tested its cameras, magnetometer, and particle-detecting instruments, capturing unusual views of Mars and measuring its magnetic environment. It also detected neutrons from the planet and spotted the tiny moons Phobos and Deimos.
NASA’s Swift Observatory observed a supermassive black hole ripping apart a star more than 30,000 light-years from the center of a distant galaxy. The extraordinary flare briefly outshone its entire host galaxy in ultraviolet light and revealed a black hole about a million times the Sun’s mass.
Scientists have created an “electron lighthouse” that uses laser light to launch and steer electrons through a semiconductor without an applied electrical field. The quantum effect could eventually improve optical sensors, communications, imaging, and information storage.
Scientists have created twisted laser beams that interact differently with right-handed and left-handed molecules, revealing their identity through the fragments they produce. The approach could provide a faster, simpler, and more sensitive way to analyze important molecules used in chemistry and pharmaceuticals.
A major review found that exercise produces only small average improvements in hip osteoarthritis pain and physical function. It may still help some people, but researchers warn that current evidence is too limited to know which exercises work best.
A single 30-minute sauna session may briefly put the immune system on higher alert. Finnish researchers found that sauna heat, paired with a short cold shower, increased every type of white blood cell circulating in the bloodstream, including key infection fighters such as neutrophils and lymphocytes.
Lake fly larvae plunge more than 200 meters into Lake Malawi each day to hide from predators, using tiny air sacs to control their depth. A rubber-like material called resilin lets them expand or shrink the sacs by changing their pH. Their toughness challenges a popular explanation for why insects are absent from the open ocean.
