June 30, 2026 Researchers have uncovered an unexpected antiviral defense system in sea anemones that works very differently from the one humans use. The discovery suggests evolution developed multiple ways to combat viruses, challenging long-held ideas about how ...
June 23, 2026 Researchers uncovered why H5N1 bird flu attacks cows’ udders instead of their lungs: the virus’s preferred receptors are concentrated in mammary tissue. The breakthrough could help scientists predict future bird flu jumps and spot unusual ...
June 23, 2026 Researchers found that highly drug-resistant bacteria from hospitals are also resistant to glyphosate, a commonly used weedkiller. The discovery suggests that agricultural herbicides may be helping ...

June 5, 2026 Scientists have successfully tested an AI-designed universal coronavirus vaccine in humans for the first time, finding it to be safe and well tolerated. The vaccine generated immune responses against ...
May 31, 2026 Melanoma may not become steadily more dangerous with age as scientists once assumed. In a surprising discovery, researchers found that cancer spread was lowest in young mice, surged in middle-aged ...
May 28, 2026 A new brain imaging study has found no evidence of widespread brain inflammation in patients suffering from prolonged symptoms after COVID-19 ...
