Endogenous retroviruses are ancient pieces of viral DNA embedded throughout mammalian genome. Thought to be relatively inert, they are not infectious, because they lack the full complement of viral ...

Individually tailored RNA or DNA-based molecules are able to reliably fight off viral infections in plants, according to a new study. The researchers were able to fend off a common virus using the new ...

In a recent study published in the journal Cell, researchers developed a deep learning model, "LucaProt," a transformer-based AI model to detect highly divergent ribonucleic acid (RNA)-dependent RNA ...

You're walking around right now carrying the genetic fingerprints of infections that happened millions of years ago. Deep inside your cells, woven into the very fabric of your DNA, sit sequences that ...

Add Yahoo as a preferred source to see more of our stories on Google. HERVs, or human endogenous retroviruses, make up around 8% of the human genome, left behind as a result of infections that ...

Across all domains of life, immune defenses foil invading viruses by making it impossible for the viruses to replicate. Most known CRISPR systems target invading pathogens' DNA and chop it up to ...

Researchers at San Diego State University and Michigan State University are shedding new light on how viruses meticulously pack their genetic material — a breakthrough that could help researchers ...

A new study by researchers at Bar-Ilan University has uncovered that certain ocean viruses—specifically RNA viruses—may disrupt how carbon and nutrients are recycled in the ocean, potentially altering ...

Using genomics, evolutionary biologists test several hypotheses on the origin of viruses. New evidence suggests they may have emerged more times than previously thought. Corroborating the virus-first ...
