But it makes sense to me that having viruses around, what we can say with a fair amount of accuracy is because viruses require the host cell to make more copies of itself, there's no way it's silent.

Identifying viruses associated with red tide can help researchers forecast bloom development and understand environmental factors that can cause blooms to disband.

When exposed to sunlight, viruses in water survived less than 24 hours on a sunny day. But on cloudy days, they remained viable for around 2.5 days.

But healthy people are rife with viruses that don’t make us ill. Scientists estimate that tens of trillions of viruses live inside of us, though they’ve identified just a fraction of them.

Some viruses 'freeze' their RNA to replicate, study finds by Kendall Daniels, University of North Carolina at Chapel Hill School of Medicine Editors' notes ...

Hundreds of vials containing live viruses have gone missing from a laboratory in Australia, sparking an investigation. Queensland Health Minister Tim Nicholls announced today that 323 samples of ...

This doesn't help settle the matter of whether viruses or bacteria emerged first, however, because that same data suggests the first cells were already living in an ecosystem teeming with viruses.

Roundworms harbor viruses, which could be responsible for these parasites' painful symptoms in humans, scientists theorize. When you purchase through links on our site, we may earn an affiliate ...

But before you throw out your toothbrush or take apart your shower, keep in mind that the vast majority of viruses Hartmann and her team found were specific species known as bacteriophages, or ...

Most of the viruses, which aren’t harmful to humans, came from the toothbrushes, and many hadn’t been described before. “That’s wild, it just underscores how much novel stuff is out there ...

One company is aiming to treat infections with a different strategy: arming tiny viruses called bacteriophages with Crispr. Known as phages for short, these viruses naturally infect and kill bacteria.
