Scientists Plan to Resurrect the Woolly Mammoth This Decade

The company, known as Colossal, has picked up $15 million in funding to begin work on the project. This is not a Jurassic Park scenario — Colossal isn’t going to clone the original woolly mammoth species. Instead, it will use CRISPR to make modifications to the genome of the endangered Asian elephant, a creature that shares over 99.9 percent of its DNA with its extinct cousin.

According to Church, who has been musing about resurrecting the mammoth for years, the team has already identified the mammoth genes that gave the animals shaggy coats, small ears, and more body fat. Theoretically, it should be possible to add these genes to the Asian elephant to create something that looks an awful lot like a woolly mammoth. These animals would be able to survive the intense cold in northern latitudes just like the original animals.

Colossal hopes that resurrecting the mammoth will bring attention to climate change and the loss of species. While there won’t be a Jurassic Park-style tourist attraction, Colossal has identified a 60 square mile region in northern Russia where researchers can test ideas about rewilding — that is, reintroducing the engineered mammoths into the environment. Among other things, Colossal believes that mammoths could help remake the land by knocking down trees and trampling the ground to eliminate snow cover. That could lead to the return of grasslands that insulate the ground and prevent seasonal thawing, which is breaking down permafrost and releasing massive amounts of carbon dioxide and methane greenhouse gases as the planet warms.

Not everyone is convinced that de-extinction is the best use of time and energy when it comes to protecting the environment. However, Colossal contends that this technology could eventually help bring back other species and even prevent others from going extinct by increasing the genetic diversity of endangered creatures.

In order to make any of this happen, Colossal will need to develop new genetic tools and possibly even artificial womb technology. Even if the effort to resurrect the mammoth is unsuccessful, those technologies could be valuable. That helps explain why investors were ready to pump $15 million into a moonshot company. If Colossal can turn vision into reality, the first engineered mammoths could be born as soon as 2027.

Scientists Confirm the Presence of Water on the Moon

Scientists have confirmed the discovery of molecular water on the moon. Is there any of it in a form we can use? That's less clear.

Review: The Oculus Quest 2 Could Be the Tipping Point for VR Mass Adoption

The Oculus Quest 2 is now available, and it's an improvement over the original in every way that matters. And yet, it's $100 less expensive than the last release. Having spent some time with the Quest 2, I believe we might look back on it as the headset that finally made VR accessible to mainstream consumers.

SpaceX Launches ‘Better Than Nothing’ Starlink Beta

Those lucky few who have gotten invitations to try the service will have to pay a hefty up-front cost, and the speeds aren't amazing. Still, it's a new generation of satellite internet.

Samsung, Stanford Built a 10,000 PPI Display That Could Revolutionize VR, AR

Ask anyone who has spent more than a few minutes inside a VR headset, and they'll mention the screen door effect. This could eliminate it for good.
