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 degr…

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.

Scientists have uncovered a surprising genetic connection to spinal degeneration and found that an existing osteoporosis drug can prevent damaging mineral buildup in zebrafish spines. The discovery could pave the way for new treatments that slow or prevent a major cause of chronic back pain.

A surprising discovery from Rockefeller University suggests that a common amino acid could play a powerful role in protecting against cancer and viral infections. Scientists found that low arginine levels interfere with the immune system's ability to recognize dangerous cells, while increasing arginine intake reduced colon cancer tumors and improved viral infection outcomes in mice. Even more rem…

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 powe…

ESA’s Euclid space telescope has discovered 31 ancient quasars, including two record-breaking objects that shone with the brightness of a trillion Suns when the Universe was just 670 million years old. Powered by supermassive black holes, these extraordinary cosmic beacons reveal a time when the first galaxies were still taking shape.

Dinosaurs may have been snacking on seaweed and other ocean foods more than 100 million years ago, according to surprising new evidence hidden in their fossilized teeth. Researchers discovered chemical signatures suggesting that coastal dinosaurs and other prehistoric animals relied partly on nutrients originating in the sea. The findings reveal that marine resources traveled through ancient food…

Scientists have discovered how to use flashes of laser light to organize tiny electrical regions inside a crystal, solving a decades-old mystery about how the material behaves. The laser-induced alignment lasts just a trillionth of a second, but the breakthrough could open the door to new ways of processing and storing information.

A groundbreaking drone survey has revealed a startling split in the fate of New Zealand's endangered Erect-crested penguins. While one population has remained stable for decades, another has declined by more than 40%, apparently due to a combination of predators, worsening storms, and changing ocean conditions. Even more surprisingly, the tiny Bounty Islands support nearly as many breeding pairs …

Scientists have uncovered a hidden warning sign in routine heart scans that could predict sudden cardiac death before it strikes. The AI-powered discovery outperformed conventional screening methods, potentially revealing thousands of people at risk of a fatal heart malfunction that doctors might otherwise miss.

A simple change to your daily routine could make a surprising difference in how you feel, both physically and mentally. University of Missouri researchers found that older adults who followed consistent daily schedules reported less physical pain and fewer symptoms of depression, even when they struggled with insomnia. Keeping regular times for sleeping, eating, and other activities may help regu…

Scientists have developed a promising new fiber supplement that improves gut health in people with irritable bowel syndrome (IBS) without worsening bloating, pain, or other digestive symptoms. The specially designed blend also improved gut-related anxiety and produced surprisingly rapid changes in gut bacteria, potentially offering a new way to manage IBS.

Astronomers have uncovered a potentially enormous new dwarf planet beyond Pluto, hidden for years in one of the most crowded regions of the night sky. The discovery of 2026 ED138 could expand the solar system's official dwarf planet family and hints that more mysterious worlds may be lurking far beyond Neptune.
