Scientists have discovered that fasting for just 24 hours increases a beneficial gut bacterium that helps the intestines regenerate after radiation damage. The preclinical findings could pave the way for new treatments that protect healthy tissue during cancer therapy, potentially without requiring patients to fast.
Scientists investigating a 2,800-year-old Siberian tomb discovered roughly 1,000 cannabis seeds and chemical evidence suggesting ancient Scythians used the plant for its intoxicating effects. The remarkable find, surrounded by evidence of elaborate burial rituals and animal sacrifices, offers the oldest directly dated archaeological evidence of psychoactive cannabis use.
Scientists have discovered a compound that transforms a natural muscle-repair protein into a more powerful version dubbed "Super HGF," more than doubling its ability to bind to a key receptor while protecting it from age-related chemical damage. The breakthrough, supported by early mouse experiments, could eventually help combat muscle loss and preserve strength as people age.
Eating an avocado and a cup of mango every day may provide surprising benefits for heart health, according to a new study involving adults with prediabetes. After just eight weeks, participants experienced significant improvements in blood vessel function and diastolic blood pressure, particularly among men. These benefits occurred without weight gain or changes in calorie intake, suggesting that the nutrient-rich combination could support cardiovascular health through a simple dietary adjustment.
Scientists have uncovered an unexpected connection between inflammation during pregnancy, placental damage, and autism-like traits in male mice, while females appeared naturally protected. The discovery could help explain why autism is diagnosed more frequently in boys and reveal new opportunities for early intervention.
A surprising new study suggests that eating peanuts every day could help support brain health and memory in older adults. Researchers found that consuming about two servings of unsalted, skin-roasted peanuts daily for 16 weeks improved insulin responsiveness in brain regions important for memory, a function that often weakens with age and has been linked to Alzheimer's disease.
Scientists at Johns Hopkins University have uncovered a surprising process that helps humans develop sharp vision before birth, challenging decades of assumptions about how the eye forms. Using miniature human retinas grown in the lab, researchers discovered that a vitamin A derivative and thyroid hormones work together to shape the foveola, the tiny region at the center of the retina responsible for our sharpest vision.
NASA’s Artemis I mission has revealed that cosmic radiation near the Moon is higher than in Earth orbit, but not by as much as scientists might expect. Tiny experimental detectors also uncovered surprising details about how radiation passes through the human body, offering valuable insights for future lunar exploration.
Why do some people stay mentally sharp even when their brains show signs of Alzheimer’s disease? Scientists in the Netherlands may have uncovered an important clue hidden in a rare group of immature brain cells. Researchers discovered that these cells remain present even in people over 80, but their behavior differs dramatically between those who develop dementia and those who remain cognitively healthy.
Anthropic’s IPO prospectus is 355 pages and full of never before disclosed company information.
SPOILER ALERT: This article contains major spoilers for “The Cycle,” now streaming on Shudder. What if a werewolf continued to transform even after its death? This light bulb idea came to frequent collaborators Jordan Downey and Kevin Stewart as they were sketching out a TV treatment for their 2018 film “The Head Hunter.” “We both […]
A seven-year study found that people with Parkinson’s disease who were more physically active experienced slower declines in memory, thinking, and movement abilities. Those exercising more than eight hours per week showed almost no average cognitive decline, suggesting that staying active may offer important benefits as the disease progresses.
Scientists have discovered why common marmosets have unusually small, smooth brains despite starting development much like other primates. The secret lies in subtle changes to brain-building cells that slow neuron production, revealing new clues about how the large, folded human brain evolved.
A new study tracking 13 astronauts suggests that the human heart may be surprisingly well equipped for a journey to Mars, especially with regular exercise during spaceflight. Researchers found that astronauts' hearts adapted to months of weightlessness and handled simulated Martian gravity without major problems, offering new hope for future missions to the Red Planet.
A surprising clinical trial suggests that taking vitamin C daily could improve survival in people with precancerous blood disorders and early-stage blood cancers. Patients receiving the supplement had fewer adverse events and showed a promising survival advantage, raising hopes that a common vitamin could help protect against leukemia-related complications.
Researchers have identified striking parallels between Sigmund Freud’s century-old theories and modern neuroscience, suggesting that the brain’s constant predictions shape how we experience reality. The findings could help explain why harmful thought patterns are so difficult to break and offer new insights into treating mental disorders.
Scientists have discovered that many common sweeteners can interfere with gut bacteria, with some combinations involving medications producing surprisingly strong effects. One sweetener mixed with a widely prescribed antidepressant reduced beneficial bacteria and microbial diversity in laboratory experiments, raising new questions about potential effects on gut health and immunity.
A catastrophic volcanic eruption 7,300 years ago devastated Japan, but new research reveals that its impact on prehistoric populations was far more complex than previously believed. While some communities disappeared or declined, others unexpectedly flourished as survivors migrated, adapted, and found new ways to thrive.
Scientists have discovered that some forest soils are becoming surprisingly better at removing methane from the atmosphere as temperatures rise and rainfall declines. A study spanning up to 24 years found methane absorption increasing by an average of 3% annually, challenging previous predictions about climate change's effects on forests.
Scientists have discovered that unusually small cancer cells carrying extra chromosomes can be far more aggressive than larger ones, growing faster, spreading more readily, and resisting common treatments. The surprising finding could help explain why some tumors are especially dangerous and provide a new way to predict cancer outcomes.
