When Being Larger in Size in Earth’s Past May Have Led to Extinction

Posted by in category: existential risks

When the bird on the left died off 65 million years ago, why did the one on the right thrive?


Janavis, a beak-toothed bird died while another species called the Wonderchicken survived. Could being smaller explain why the latter lived?

IBM: Quantum computing poses an ‘existential threat’ to data encryption

Posted by in categories: business, computing, encryption, existential risks, quantum physics, security

Check out all the on-demand sessions from the Intelligent Security Summit here.

For years, encryption has played a core role in securing enterprise data. However, as quantum computers become more advanced, traditional encryption solutions and public-key cryptography (PKC) standards, which enterprise and consumer vendors rely on to secure their products, are at serious risk of decryption.

Today, IBM Institute for Business Value issued a new report titled Security in the Quantum Era, examining the reality of quantum risk and the need for enterprise adoption of quantum-safe capabilities to safeguard the integrity of critical applications and infrastructure as the risk of decryption increases.

Madagascar extinction recovery could take 23 million years

Posted by in categories: existential risks, sustainability

The long-term impact of biodiversity loss in Madagascar has been modelled by researchers. Their work suggests that recovery from the current wave of extinctions could take as long as 23 million years.

Madagascar is one of the world’s most biodiverse hotspots. Following the breakup of the prehistoric supercontinent of Gondwana, the island country split away from the Indian subcontinent about 80 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, over 90% of its wildlife is endemic and found nowhere else on Earth.

Dinosaur Legs Grown On Genetically Modified Chicken Embryos In World First

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

Sixty-six million years ago, the age of the dinosaurs came to a dramatic close as a huge asteroid impact accelerated them on a path towards extinction. Not all of them died out, however; those that survived went on to become today’s birds.

Scientists are still trying to carefully map out the anatomical changes that occurred between dinosaurs and birds during this time, and there’s arguably no better way to do this than to engage in a little “reverse evolution.” With this in mind, a team of researchers has grown “dinosaur legs” in chicken embryos, as revealed in their study in the journal Evolution.

Remarkably, previous research manipulating chickens into “becoming” dinosaurs has already taken place. Back in 2015, a study showcased that chickens that had been tweaked during embryonic development could grow a dinosaur-like snout. A year earlier, a more low-tech study demonstrated how a few strategically-placed weights could make a chicken walk along like a Tyrannosaurus rex.

NASA’s plan to identify dangerous asteroids takes a major step forward

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

The NEO Surveyor will be able to detect individual asteroid heat signatures.


NEO Surveyor is, as the name implies, a satellite specifically designed to survey objects near the Earth (NEO). One of its primary contributions will be to look for asteroids and other small bodies that are potentially on an eventual collision course with Earth but are invisible to typical NEO survey missions because of their location in the solar system.

Chicxulub crater might be the smoking gun for the dinosaurs’ end of days

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

Forged 66 million years ago, an enormous impact crater near Chixculub, Mexico, was left undiscovered until only a few short decades ago. But what caused it?

Millions of years ago, a dramatic mass extinction wiped out the dinosaurs.
