The Download: Gene de-extinction, and Ukraine’s Starlink connection

This week witnessed the issuance of some wonderful news about some of the very unique rodents-which are called “woolen mice”-created as part of an experiment to explore how we can one day revive the Sufi mammoth.

The idea of ​​returning extinct species gained traction thanks to the progress of the old DNA sequence. This old genetic data deepens our understanding of the past – for example, by shedding light on prehistoric human reactions. But researchers have become more ambitious. Instead of just reading the old DNA, they want to use it – by inserting it into living organisms.

Since this idea is very new and attracted a lot of attention, I decided that it would be useful to create a record of previous attempts to add extinct DNA to living organisms. Since technology does not have a name, let’s give it one: “Chronogenics”. Read the full story.

+ How much you will pay to see Mammoth Sophie? We have talked to Sarah Urd, the director of species restoration at Colossal, the first company “De-Extirmction” in the world, about its great ambitions.

+ Colossal is also an expanded company, trying to revive Dodo. Read the full story.

+ DNA, which has been frozen for two million years. Old DNA fragments come from an ecosystem in Greenland, where the mascudon wanders between flowering plants. Evidence of how to survive is a warming climate.
