Scientists have discovered that vitamin C may help prevent potentially cancer-causing chemicals from forming in the stomach after eating foods containing nitrates and nitrites. A new mathematical model suggests that taking vitamin C after meals could reduce these harmful reactions, offering a possible new strategy for lowering cancer risk.

NASA scientists warn that the rapidly intensifying 2026 El Niño could surpass the historic 1997-98 event, which triggered devastating weather extremes around the world. Satellite data reveal striking similarities between the two, raising the possibility of major rainfall and flooding this winter, although the exact impacts remain uncertain.

The strange, wildly tilted magnetic fields of Uranus and Neptune have puzzled scientists since NASA's Voyager 2 spacecraft explored the planets in the 1980s. New simulations suggest that extreme conditions deep inside these icy giants create unusual electrical properties that could explain their magnetic fields. Remarkably, the models indicate that their magnetic poles could shift by tens of degrees within just a few decades, far faster than Earth's.

Scientists have discovered a strange stellar pair more than 5,000 light-years away, where a dead star spinning every eight minutes produces mysterious radio pulses while orbiting a Sun-like star. The breakthrough also revealed massive magnetic storms on the companion star, offering fresh clues to one of astronomy's emerging mysteries.

Johns Hopkins scientists have uncovered hidden warning signs of Alzheimer’s disease that may appear up to a decade before memory loss begins. Brain scans revealed that two regions involved in memory and emotion start shrinking before the hippocampus, the area doctors typically examine for signs of Alzheimer’s. These early changes are linked to abnormal tau protein buildup and could provide a powerful new way to identify people at risk.
