Kei Sato was looking for his next big challenge five years ago when it smacked him — and the world — in the face. The ...

Scientists have also generated more than 17 million SARS-CoV-2 genome sequences so far, more than for any other organism. This has given an unparalleled view into the ways in which the virus ...

Mosquitoes have been transmitting the West Nile virus to humans in the United States for over 25 years, but we still don't ...

A screen of human-infecting viruses identified extensive examples of viral proteins that resembled human sequences, which ...

Cas9, scientists reconstitute live African swine fever virus from synthetic genomes, accelerating vaccine development for ...

It's been five years since COVID-19 was declared a global pandemic. As SARS-CoV-2 shifts to endemic status, questions about ...

A phylogenetic tree of SARS-CoV-2 sequences, built with Nextstrain, displays sequences colored by their clade and organized by collection date. Over time, sequences mutate and diverge, forming new ...

So how do they know with such certainty? The key is in the virus's genetic code. This is the genomic sequence for SARS-CoV-2. It was decoded in January 2020, just weeks after the world started to ...

Sequence variations in human immunodeficiency virus (HIV)-1 reverse transcriptase (RT) and protease, the molecular targets of anti-retroviral drug therapy, are prime examples of genes in which ...

H5N1 influenza is evolving rapidly, weakening the effectiveness of existing antibodies and increasing its potential threat to ...

"If those sequences don't exist on a DNA or RNA fragment in a sample ... Viral bioreactors don't produce a steady amount of virus, due to the way viruses are produced throughout the cell cycle.
