The belief that huge doses of vitamin C can ward off colds was popularized more than 50 years ago by Nobel Prize winner Linus Pauling. Since then, larger studies have found that vitamin C does not prevent most people from catching a...
Backyard bird feeders could become unexpected hotspots for H5N1 as Australia’s bird flu outbreak spreads, bringing species together in ways that rarely occur naturally. Experts say stopping feeding is safest, while smaller amounts of...
AI may be able to predict how strongly someone will respond to a vaccine before they receive it. By analyzing antibody patterns in more than 4,000 people, researchers found signs of “immune readiness” that helped distinguish strong...
Australia has recorded more than 200 confirmed detections of H5 bird flu in wild birds, raising concern over the virus's rapid spread and its potential
Australia is facing what scientists describe as a potential wildlife emergency after the highly pathogenic H5N1 avian influenza virus began spreading through wild seabird populations.
Nepal has indefinitely closed its Central Zoo in Kathmandu after authorities confirmed cases of highly pathogenic avian influenza (medlinkH5N1/medlink),
A new study examining more than 11,000 bYouTube videos and user comments has revealed how public conversations about avian influenza shifted as the outbreak evolved.
For most adults, a daily caffeine habit may be safer for the heart than many people assume. A new American Heart Association review found that up to 400 milligrams of caffeine a day, roughly three to five cups of regular black coffee, is...
Scientists uncovered how influenza A commandeers human cells, including a surprising strategy that dissolves tiny structures in the nucleus and releases proteins the virus may use to reproduce. The detailed molecular map could reveal new...
Many of the body's biggest flaws are the result of evolution building on old designs instead of starting over. Our spine, eyes, teeth, pelvis, and even certain nerves all reveal compromises that worked well enough for survival but still...
A new intranasal DNA vaccine may give the immune system an extra weapon against tuberculosis by targeting bacteria that can hide from antibiotics. In animal studies, it helped clear infections faster, reduced lung inflammation, and...
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...
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 multiple coronaviruses, including...
Scientists have finally cracked one of the biggest mysteries in the senses: how smell is organized. By mapping millions of neurons in mice, researchers discovered that smell receptors in the nose aren’t random at all—they’re arranged in...
A new nanodisc-based platform lets scientists study viral proteins in a form that closely mimics real viruses, revealing how antibodies truly recognize them. This approach uncovered hidden interactions in viruses like HIV and Ebola that...
mRNA vaccines saved millions of lives during COVID-19 but have limitations like waning immunity and complex production. Scientists are now testing a new platform called DoriVac, which uses folded DNA nanostructures to better control how...
Scientists at Stanford Medicine have unveiled a bold new kind of “universal” vaccine that could one day protect against everything from COVID-19 and the flu to bacterial pneumonia and even common allergens. Instead of targeting a...
