Scientists may have solved why the length of Earth's day changes by a few milliseconds over decades. Subtle shifts in the inner core appear to tug on the mantle, revealing a surprisingly dynamic world thousands of kilometers beneath our feet.
A new study suggests coffee may influence mood and brain function by changing the activity of microbes in the gut. Both caffeinated and decaf coffee were linked to lower stress, depression, and impulsivity, while also producing measurable changes in ...
Spaceflight may dramatically change the gut within weeks, causing bacteria to break down more protein as food moves more slowly through the intestines. The shift could help explain astronaut constipation and may have wider effects on health, making . ...
A compound the body can make after eating pomegranates, walnuts, and some berries improved measures of heart function by up to 80% in animal models of a difficult-to-treat form of heart failure. Urolithin A helped stiff heart tissue relax and reduced ...
Scientists resurrected antimicrobial peptides from mammals that lived millions of years ago and found that some were more potent against drug-resistant bacteria than modern human versions. These evolutionary relics could provide new clues for ...
Ancient DNA shows that adults and children buried together in medieval Sweden were often not members of the same immediate family, suggesting that burial choices reflected more than biological kinship. The research also revealed early gender-based .. ...
Scientists have mapped the genetics of cat cancer on an unprecedented scale and found surprising similarities with tumors in humans. The findings could help bring precision cancer treatments to cats while also revealing new clues about how human ...
Scientists think beneficial fungi could help transform nutrient-poor lunar and Martian regolith into a material capable of supporting crops. By helping plants access nutrients and withstand harsh conditions, these microbes could someday make self ...
Scientists discovered two strange new sea spider species in the Salish Sea, including a hairy-legged, red-eyed species that can groom itself with comb-like appendages. Another is frequently covered in tiny parasites, and researchers say many more ...
A dead white dwarf with no detectable disk has somehow produced a powerful shock wave that appears to have persisted for at least 1,000 years. Its magnetic field may be partly responsible, but astronomers say an unexplained "mystery engine" may also ...
