Underground dome house of the family who led geese to fly home

Posted by in categories: existential risks, transportation

Paula and Bill Lishman spent many winters in a poorly-insulated A-frame cabin before realizing they needed to go underground to use the earth’s energy to stay warm, so they knocked the top off a hill, dropped in ferro-cement domes, and covered it up again with dirt.

Thanks to skylights cut into every dome and the white-powdered marble that covers the interior, their earth-sheltered home is naturally well-lit despite being below the frost line.

“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.
