Summary

Today you’ll learn about a zombie virus recovered from the arctic permafrost and brought back to life, some good news about 26 Australian animal species that have been brought back from the brink, and how a new pill could potentially limit the levels of “bad” cholesterol in the body.

0:00.0	Hi, you're about to get smarter in just a few minutes with Curiosity Daily from Discovery.
0:09.0	Time flies when you're learning super cool stuff.
0:11.0	I'm Nate.
0:12.0	And I'm Kali. If you're dropping in for the first time, welcome to Curiosity where we aim to blow
0:15.8	your mind by helping you to grow your mind. If you're a loyal listener, welcome back.
0:19.7	Today you'll learn about a zombie virus recovered from the Arctic permafrost and brought back to life.
0:26.1	Some good news about 26 Australian animal species that have been brought back from the brink
0:31.5	and how a new pill could potentially limit the levels of bad
0:34.7	cholesterol in the body. Without further ado, let's satisfy some curiosity.
0:39.2	Hey Nate, can we talk about zombie viruses? We can, but that doesn't mean that we have to if you ask me.
0:45.2	Do we have to?
0:47.2	We kind of do, yes.
0:48.8	And it's not just because it's a super cool segment for the podcast,

0:58.3	You're kidding me, right?
0:59.9	No, I kind of wish I was. Jean-Michel Cleverie, an emeritus professor of Medicine and Genomics in Marseille, France, has been finding and studying viruses frozen in the permafrost since 2014.
1:12.0	He and his team inserted a 30,000 year old virus into
1:15.2	cultured cells, so just cells that are designed to live in the laboratory environment, which
1:20.1	revived it. They did it again in 2015 and have recently published research in the journal
1:25.5	Viruses showing that several new strains that were gathered in different locations across
1:29.4	Siberia could infect cultured amoeba cells which is important because this proves
