Misfolded insulin may be quietly driving diabetes

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.

Hidden charcoal reveals the true age of ancient cave paintings

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.

Why losing weight may not be enough to prevent type 2 diabetes

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 aces Mars flyby capturing stunning timelapse video

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.

Scientists create an “electron lighthouse” with laser light

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.

Twisted laser light can tell mirror-image molecules apart

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 single sauna session sends immune cells surging

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.
