In simple terms: a virus is a tiny package of genetic instructions with a delivery system. Outside a cell it is metabolically inert. Once inside a susceptible cell, it redirects the cell's machinery ...

Scientists at Harvard Medical School and Boston University Chobanian & Avedisian School of Medicine have mapped a critical component of the Nipah virus, a highly lethal bat-borne pathogen that has ...

Scientists have decoded the 3D structure of an ancient viral protein hidden in our DNA. The HERV-K Env protein, found on cancer and autoimmune cells, has a unique shape that could unlock new ...

Retroviruses are viruses that have evolved the ability to write their genetic code into a cell's own DNA. The most ancient known lineage of retroviruses, foamy viruses, emerged around 450 million ...

Nipah virus is a zoonotic virus harbored by fruit bats. It can be transmitted to pigs and humans, infect people through contaminated food, and can travel directly from person to person via droplets.

Viral infection induces cytoskeleton remodeling into cage-like structure. Virus infection can cause severe rearrangement of the cytoskeleton, and all three kinds of cytoskeleton form a cage-like ...

More than 200,000 children succumb to viral gastroenteritis infections, or stomach flu, all over the world every year. 1 Human astroviruses are a common cause of such infections, leading to diarrhea, ...

Herpes simplex virus partially liquefies the tightly packed, gel-like interior of human cell nuclei to copy itself faster, a new study shows. The research centers on how the nucleus of each human cell ...
