Horses possess a rare genetic peculiarity. This adaptation partly explains their exceptional endurance without compromising ...

New research shows how small shifts in the molecular makeup of a virus can profoundly alter its fate. These shifts could turn ...

For decades, the human niche for viruses related to smallpox has remained mostly empty. Since eradicating smallpox, only rare ...

So far, Alabama is the only place it's been discovered, although short-tailed shrews can be found across North America. However, according to the Economic Times, virologists warn that it's only a ...

"We know that the virus is only one or two mutations away from being able to cause severe disease in humans." The current risk to humans remains "very low," according to the CDC, but the virus has ...

After nine cases of mpox were confirmed in the UK, health officials downgraded the risk of the virus from "high consequence ...

When the virus enters an individual’s body, it aims at creating copies of itself. When it makes an error in this copying process, we get a mutation. In this case ...

A mutation in the H5N1 bird flu virus, linked to increased infectiousness and disease severity, was identified in two cats. This mutation, PB2 E627K, is associated with enhanced mammal-to-mammal ...

“The problem is that flu viruses acquire mutations all the time. And we know that the virus is only one or two mutations away from being able to cause severe disease in humans.” The current ...

The researchers found that a single mutation in the virus's spike protein was enough to prevent it from attaching to human and horse cells. The mutation, however, still allowed the virus to enter ...
