GLP-1 drugs like tirzepatide and semaglutide offer powerful weight-loss effects but come with unanswered questions about long-term safety, side effects, and global accessibility. Researchers stress the need for independent studies before these ...

Penn State scientists identified a striking rise in melanoma across several Pennsylvania counties dominated by cropland and herbicide use. The elevated risk persisted even after factoring in sunlight, suggesting an environmental influence beyond the ...

Researchers combined deep learning with high-resolution physics to create the first Milky Way model that tracks over 100 billion stars individually. Their AI learned how gas behaves after supernovae, removing one of the biggest computational ...

LHAASO has uncovered that micro-quasars, black holes feeding on companion stars, are powerful PeV particle accelerators. Their jets produce ultra-high-energy gamma rays and protons that exceed long-held expectations. Precise cosmic-ray measurements . ...

Researchers at KRISS observed water's rapid freeze-melt cycles under ultrahigh pressure and discovered Ice XXI, the first new ice phase found in decades. Using advanced high-pressure tech and microsecond XFEL imaging, they uncovered complex ...

Researchers found that ancient hominids--including early humans--were exposed to lead throughout childhood, leaving chemical traces in fossil teeth. Experiments suggest this exposure may have driven genetic changes that strengthened language-related ...

A newly recognized set of T helper cells seems to guard against aging by eliminating harmful senescent cells. Their presence in supercentenarians suggests they may be a key to maintaining a healthier, age-balanced immune system.

Dark matter may be invisible, but scientists are getting closer to understanding whether it follows the same rules as everything we can see. By comparing how galaxies move through cosmic gravity wells to the depth of those wells, researchers found .. ...

Chimps may revise their beliefs in surprisingly human-like ways. Experiments showed they switched choices when presented with stronger clues, demonstrating flexible reasoning. Computational modeling confirmed these decisions weren't just instinct. .. ...

Aalto University researchers have developed a method to execute AI tensor operations using just one pass of light. By encoding data directly into light waves, they enable calculations to occur naturally and simultaneously. The approach works ...
