Extinction

Scientists have successfully extracted RNA from an extinct species for the first time. This was achieved in the thylacine, a species of carnivorous marsupial that roamed Australia until a century ago – and may again one day, if current plans bear fruit.

Scientists have used fossilized megalodon teeth to estimate the ancient shark’s body temperature, and found it wasn’t exactly a cold-blooded killer. Strangely enough, that might have contributed to its downfall.

Forget the collapse of employment, forget the spam and misinformation, forget human obsolescence and the upending of society. Some believe AI is flat-out going to wipe out all of biological life at its earliest opportunity. Here's how and why.

A new study has found that sea and land wildlife are the "missing link" between biodiversity and climate. By protecting and restoring wildlife we can enhance natural carbon capture mechanisms and reduce climate change.

Not content with the woolly mammoth and the thylacine, Colossal Biosciences has now announced the third animal on its de-extinction list – the dodo. The company has received new funding, and provided an update on its scientific progress so far.

In Hokkaido, Japan's winter months, harmless underwater algae balls are protected from death by an ice shield. That shield is expected to thin thanks to global warming, causing the balls to join the list of species threatened by climate change.

Famous video of a thylacine in captivity may not depict the last member of the species after all, according to new research. Australian scientists have rediscovered the preserved remains of a later thylacine in the collection of a museum in Tasmania.

It's thought the Earth is currently entering its sixth major extinction event, but a new study suggests it may actually be the seventh. Scientists have found evidence of a previously unknown mass extinction event that struck half a billion years ago.

Researchers have created induced pluripotent stem cells from the genetic material of the critically endangered Sumatran rhino, potentially providing new ways to help conservation efforts. They even used them to grow mini rhino brains in lab dishes.

Scientists have discovered a new crater in the seabed of the North Atlantic Ocean that seems to date to the end of the Cretaceous period. That suggests the extinction event that killed off the dinosaurs could have been triggered by multiple impacts.

Colossal has plans to resurrect the mammoth, and now it's revealed the second species on its de-extinction list – Australia’s lost thylacine. Partnering with a University of Melbourne lab, the project could revive the creature in about a decade.

A new company called Colossal plans to revive the woolly mammoth and reintroduce the species to the Arctic. And it isn’t meant to be just a tourist-trap Jurassic Park either – the aim is to restore a long-lost ecosystem to help fight climate change.
