Phys.org / Active particles could make stable glasses stronger without catastrophic brittle failure
The strongest glasses have an Achilles' heel that causes them to fail catastrophically when pushed past their limit. They do not bend or stretch, as all damage concentrates into a single plane and the material fails in an ...
Medical Xpress / New way to help CAR-T cells fight solid tumors could change cancer treatment
For more than a decade, CAR-T cell therapy has been one of the biggest breakthroughs in cancer medicine. By reprogramming a patient's own immune cells to attack cancer, doctors have produced remarkable results against certain ...
Phys.org / Quantum Latin squares cannot solve Euler's 36 officers problem without entanglement
Latin squares are arrangements of symbols in a grid in which every symbol appears exactly once in each row and column. These symbol arrangements, which were first studied more than three centuries ago, are now widely used ...
Phys.org / Mysterious Cygnus Bubble may trace back to microquasar, astronomers suggest
Astronomers have proposed a new explanation for the mysterious Cygnus Bubble, a vast cloud of ultra-high-energy gamma rays stretching thousands of light-years across the sky. While the bubble has generally been linked to ...
Tech Xplore / AI agents struggle to perform original scientific research
Among the many predictions about the future of artificial intelligence is that models will one day be able to conduct scientific research on their own, leaving humans out of the equation. Already, they can write code, run ...
Phys.org / Flightless beetles evolved distinct snail-hunting shapes on Japan's largest island
Islands are widely recognized as natural laboratories of evolution. The ocean restricts movement among islands, allowing isolated populations to adapt to different environments and, at times, diverge into new species. However, ...
Phys.org / Rings forged from meteorites may have been fashionable among ancient Greek elites
Meteorites provided a rare but ready source of iron for ancient Bronze Age cultures before smelting became common. A new study, published in the Journal of Archaeological Science, sheds light on how the ancient Minoan and ...
Medical Xpress / New gas-switching approach could one day make deep-sea decompression safer and faster
Deep-sea divers must be careful to prevent decompression sickness, also known as "the bends," when ascending from the high-pressure depths of the ocean. Failing to do so can result in anything from muscle cramps and skin ...
Medical Xpress / Curiosity has its own neural signal: Brain separates valuable information from water rewards in mice
Often, humans and other animals seek information that can help them complete tasks and attain desired rewards. In some cases, however, they seek information driven simply by curiosity and a desire to obtain knowledge for ...
Phys.org / Human blood may have helped preserve ancient Chinese rock art for 2,000 years
The Huashan rock art landscape in southern China, close to the border with Vietnam, is a remarkable UNESCO World Heritage site. Thousands of images are painted on river cliffs across more than 80 locations stretching 260 ...
Medical Xpress / New obesity definitions reveal ill health more accurately than body mass index
Traditionally, obesity has been classified primarily using BMI, a measure of weight relative to height that provides limited information about whether excess fat is actually affecting a person's health. BMI levels have historically ...
Phys.org / Guangzhou crucibles provide earliest direct evidence of brass-making in East Asia
For centuries, scholars have read ancient documents describing the production of brass in 10th-century A.D. China. The problem was that the earliest physical evidence of brass production would be found nearly 600 years later, ...
