Scientists resurrect 700-year-old viruses

(Phys.org) —Eric Delwart of the Blood Systems Research Institute in San Francisco and colleagues have found two 700-year-old viral sequences in frozen caribou dung in an arctic ice patch. The researchers isolated part of ...

More possible branches to the domain of life

(PhysOrg.com) -- When it comes to the current domain of life, we are familiar with the three branches: bacteria, archaea, and eukaryotes. However, Jonathan Eisen of UC Davis and his team have published possible evidence ...

Model can predict the evolution of new COVID variants

An international research team from the University of Cologne and the Icahn School of Medicine, Mount Sinai (New York) has developed a model that predicts the likely evolution of variants of the SARS-CoV-2 virus.

Bat virus receptor studies vital to predict spillover risk

New research shows that the closest bat virus relatives of the human Middle-East Respiratory Syndrome (MERS) coronavirus efficiently bind to bat ACE2 receptors as an entry point into these cells. These receptors have some ...

Evolutionary analysis shows SARS-CoV-2 variants converging

An analysis of massive amounts of genetic data on the SARS-CoV-2 virus suggests that COVID-19 variants worldwide are repeatedly evolving the same mutations, according to a study published today in eLife and carried out by ...

New research finds that viruses may have 'eyes and ears' on us

New UMBC-led research in Frontiers in Microbiology suggests that viruses are using information from their environment to "decide" when to sit tight inside their hosts and when to multiply and burst out, killing the host cell. ...
