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 ...

How did viruses evolve? Are they a streamlined form of something that existed long ago, or an ultimate culmination of smaller genetic elements joined together? Aa Aa Aa The evolutionary history of ...

Researchers have proposed a new evolutionary model for the origin of a kingdom of viruses called Bamfordvirae, suggesting a billion-years evolutionary arms race between two groups within this kingdom ...

In a recent study published in Emerging Infectious Diseases, researchers determined the zoonotic transmission potential of influenza A viruses (IAVs) H3 subtype of avian, equine, and swine origin. H3 ...

Scientists estimate that the earliest biological entities began to appear on Earth more than 4 billion years ago. "There was a sort of primordial soup from which certain organic molecules were formed.

Ancient DNA reveals that childhood viruses lived with humans for thousands of years, reshaping how we understand human and ...

Infectious disease researchers have identified Pteropine orthoreovirus (PRV), an emerging bat-borne orthoreovirus, in archived throat swab samples and virus cultures from five patients in Bangladesh ...

Infectious disease researchers have identified Pteropine orthoreoviruses (PRVs), a group of newly emergent bat-borne viruses, ...

As humans alter the planet’s climate and ecosystems, scientists are looking to Earth’s history to help predict what may unfold from climate change. To this end, massive ice structures like glaciers ...

This article originally appeared on Undark. Pharmacies in the nation of Georgia have something ours don’t: vials of viruses in neat rows. People swallow or gargle the brews to combat routine bacterial ...

Events such as the World Cup could have facilitated the spread, scientists say. — -- It’s not just humans who can travel rapidly across the world. Viruses and disease-spreading insects and ...
