“Rubble pile” asteroids may be surprisingly hard to destroy — study

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

When Japan’s Hayabusa mission traveled to asteroid Itokawa, it collected samples. These successfully reached Earth in 2010.


Near Earth asteroid Itokawa is a rubble pile that formed more than four billion years ago, a new study found. So, these asteroids might be resilient to demise.

PRESS RELEASE: Doomsday Clock set at 90 seconds to midnight

Posted by in categories: existential risks, government, military, nuclear energy

Rachel Bronson, PhD, president and CEO, Bulletin of the Atomic Scientists, said: “We are living in a time of unprecedented danger, and the Doomsday Clock time reflects that reality. 90 seconds to midnight is the closest the Clock has ever been set to midnight, and it’s a decision our experts do not take lightly. The US government, its NATO allies and Ukraine have a multitude of channels for dialogue; we urge leaders to explore all of them to their fullest ability to turn back the Clock.”

The Doomsday Clock’s time is set by the Bulletin of the Atomic Scientists’ Science and Security Board with the support of the Bulletin’s Board of Sponsors, which includes 10 Nobel Laureates. Previously, the Doomsday Clock had been set at 100 seconds to midnight since 2020.

Dust particles from an asteroid could save Earth from doomsday

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

Destroying an Earth-killing asteroid is not always possible, here’s what we can do instead.

Do you know what size asteroid would be enough to end all life on Earth? According to the experts at NASA, a space rock only 96 km wide can do the job.

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.
