CRISPR is helping “de-extinct” the Tasmanian tiger

Posted by in categories: biotech/medical, existential risks

Extinction is a regular part of nature. An estimated 99% of all species that have existed on Earth have gone the way of the dodo, sometimes because a fitter competitor came along or their environment changed (often because of humans) and they couldn’t adapt.

While life can go on relatively unchanged after the extinction of some species, the loss of a keystone species — one that plays a significant role in its environment — can upend an ecosystem.

Now, researchers exploring the idea of “de-extinction” believe that science might be able to intervene and restore the balance.

‘Zero chance’ infamous Apophis collides with another asteroid, redirects to Earth

Posted by in categories: asteroid/comet impacts, existential risks

When it was first discovered in 2004, Apophis was identified as one of the most dangerous asteroids in that there was a risk that it could impact Earth. But that impact assessment changed over the years after astronomers tracked Apophis, also known as asteroid 99,942, and its orbit became better determined, and it became clear that it was on course to miss our planet.

The Fermi Paradox: Imprisoned Planets

Posted by in categories: alien life, existential risks

Getting into space is difficult, but it may be that other worlds have even harder times at it than we do, imprisoned by orbital debris, high gravity, or even being quarantined by alien civilizations.

The Fermi Paradox: Absent Megastructures

Posted by in categories: alien life, existential risks, robotics/AI

The great mystery of where all the aliens are in our vast Universe contemplates ancient interstellar civilizations building enormous megastructures that rival worlds or even stars in the immensity… and asks why we can’t see these giant alien artifacts.

Smarter than GPT-4: Claude 3 AI catches researchers testing it

Posted by in categories: existential risks, robotics/AI

Radical Plan to Stop ‘Doomsday Glacier’ Melting to Cost $50 Billion.


Working on these next-gen intelligent AIs must be a freaky experience. As Anthropic announces the smartest model ever tested across a range of benchmarks, researchers recall a chilling moment when Claude 3 realized that it was being evaluated.

Anthropic, you may recall, was founded in 2021 by a group of senior OpenAI team members, who broke away because they didn’t agree with OpenAI’s decision to work closely with Microsoft. The company’s Claude and Claude 2 AIs have been competitive with GPT models, but neither Anthropic nor Claude have really broken through into public awareness.
