Rather than a slow, gradual process as Darwin envisioned, biologists can now see how evolutionary changes unfold on much more accelerated timescales. Using an accelerated arms race between bacteria ...

In a twist on the question, 'Which came first, the chicken or the egg?', scientists have long faced a similar question about how human adenovirus replicates: 'Which comes first, assembly of the viral ...

Broadly neutralizing antibodies are those that are able to protect against a broad range of viral strains, by binding to relatively non-varying sites on the virus in ways that interrupt the viral life ...

An ancient viral infection may have given animals the tools to become fast, coordinated and smart, a study has found. According to a paper published Thursday in Cell, complex nervous systems arose in ...

Toward the goal of efficient editing of farm animals for genetic improvements, this study explores an upgraded form of nuclease PE (uPEn). Based on the resolved structure of the NiV polymerase L-P ...

Scientists at San Diego’s Scripps Research have identified antibodies that could stop the very complex virus that gives people AIDS. KPBS sci-tech reporter Thomas Fudge tells of the first clinical ...
