True! Here’s a little additional information since the north is in virus season.

A virus is a protein wrapped in a protective fatty lipid. Heat will melt the fat, then break down the protein. That’s why viruses last longer on surfaces and clothing in the cold season, increasing probability of transmission. A virus can remain intact on a shopping cart handle for up to 24 hours in the winter, for example.

You can also rapidly break down the fatty lipid using isopropyl alcohol, or break down the protein directly using hydrogen peroxide. Be careful using the latter. It can bleach or discolor dyed textiles.

Bats use heat to fly off their viruses, they get pretty bad ones, but when they're flying Bats get really hot. So it burns them off.

Also, some viruses have evolved into us and ended up serving functions in the human bawdy.

Yup. Up to 8% of the human genome is comprised of ancient viruses.

As an example we have reverse transcriptase that is derived from viruses.

There was a Kurzegadt video about the virome recently

However, I can't find it now and nor can I spell their name, so apologies on both counts

I believe you're referring to https://youtube.com/@kurzgesagt

[–] Serinus 5 points 1 week ago (1 children)

I think they're on https://nebula.tv too, if you prefer that to YouTube.

I can't see them on nebula, I just looked on the nebula app, but also on their Reddit and website

Another example; mammals probably developed pregnancy using an Autoimmune virus' genes in the placenta to prevent the fetus from being destroyed by the immune system.
