Scientists discover that some “unhealthy” diets can boost cancer immunotherapy in mice

In a surprising discovery, scientists found that certain diets associated with obesity can make cancer immunotherapy more effective in mice, challenging traditional assumptions about diet and cancer treatment. The findings suggest that the secret may lie in how food interacts with gut bacteria to strengthen the immune system's response to cancer.

New diabetes implant uses electricity to lower blood sugar and promote weight loss

Researchers have developed a remarkable new electronic implant that could transform type 2 diabetes treatment by lowering blood sugar without insulin or traditional drugs. The device uses a special electrically powered catalyst to convert excess glucose into a substance that the body eliminates through urine, potentially preventing unwanted energy from being stored as fat. In diabetic mice, the implant precisely controlled blood sugar and promoted weight loss.

Experts say high blood pressure guidelines are missing half the equation

Scientists are calling for a major rethink of how we manage high blood pressure, suggesting that eating more potassium could be just as important as cutting back on salt. A new report finds that combining increased potassium intake with reduced sodium consumption may offer greater benefits for blood pressure control than sodium reduction alone.

IceCube detects ghost particles with 10 billion times the energy of solar neutrinos

Mysterious particles called neutrinos constantly stream through our bodies, and scientists are now detecting incredibly powerful versions arriving from distant cosmic sources using a massive observatory buried in Antarctic ice. These elusive “ghost particles” could hold extraordinary clues about the Big Bang, extreme cosmic events, and some of the universe’s greatest mysteries.

Ultrashort laser pulses can slice lab-grown diamond along useful crystal plane

More than just a precious gemstone for jewelry, diamond has properties that make it attractive for several next-generation, high-performance technologies. Its high thermal conductivity can help move heat away from semiconductor devices, while its wide bandgap is promising for high-power electronics. Moreover, its transparency in the visible light range makes diamond useful for demanding optical applications.

From wild to mild: Friendly foxes show changes in brain region

Scientists studying the neurology of tame foxes identified changes in a part of the brain that has previously been associated with aggression, according to a new paper that compared the brains of domesticated, aggressive and wild foxes. The changes occurred in an area at the base of the brain called the ventromedial hypothalamus, which is known to drive aggression, control decisions related to energy use and play an important role in maternal instincts and social behaviors in mice.
