Viruses are entirely dependent on their hosts to reproduce. They ransack living cells for parts and energy and hijack the host's cellular machinery to make new copies of themselves. Herpes simplex ...

The virus that commonly causes cold sores starts reshaping our genome within an hour of infection to boost its own growth, which scientists could take advantage of to treat severe cases. Billions of ...

Human DNA in its natural state inside cells (left) compared to eight hours after being infected with HSV-1 (right). The virus compacts the human genome’s size significantly and moves it towards the ...

Discover how CRISPR genome editing is revolutionizing medicine. Learn the science of Cas9, current clinical trials, and the future of gene editing.

Scientists have long known that a significant portion of the human genome is made up of the remnants of ancient viruses; these sequences are a subset of transposable elements known as endogenous ...

A genome-wide evolutionary analysis of several viruses found no signs of pre-spillover adaptation. Instead, detectable ...

Scientists have discovered a defensive method of cells that resembles Spiderman shooting his web to ensnare enemies. These cells defend our bodies from the early stages of viral infection by ...

Distinguishing between self and non-self is a critical ability of the immune system. Some pathogens have evolved proteins that resemble those of their host, a mechanism called molecular mimicry, in an ...

Many pandemic viruses emerged naturally – but there’s one that most likely came from a lab - Research provides benchmark for distinguishing natural outbreaks from scenarios involving lab leaks ...
