What criteria or characteristics would you use to group living things versus nonliving things? Scientists have grappled with this question for years, and the debate is still ongoing in the scientific ...

Left: Structure of the Human Immunodeficiency Virus (HIV). Note the envelope protein that protects the virus against immunological detection and the small genome consisting of two short strands of RNA ...

Colorized transmission electron micrograph of HIV-1 virus particles (yellow) budding and replicating from an H9 T cell (dark blue). The virus particles are in various stages of maturity, which ...

Scientists at the University of Virginia School of Medicine have developed a method to understand how HIV and other viruses first begin to infect our cells, and that could help us prevent COVID-19 and ...

Viruses need host cells, and viral pathogens have many different ways to infect those hosts. Scientists have revealed a rapid movement made by a small molecule called a glycoprotein on the surface of ...
