Advanced computer models can quantify the impacts of climate change and other environmental challenges, providing deep ...

Earth set its chemical identity in three million years, but habitability came later after a planetary collision.

Around 4.5 billion years ago a giant object around the size of Mars crashed into the proto-planet Earth, called Theia. This essentially redid the planet and created the Moon, but new research suggests ...

The CRASH Clock is a new metric for measuring the risks of satellite congestion in low-Earth orbit. Its calculations are disturbing. Reading time 2 minutes Last week, a Chinese spacecraft passed ...

Fusion power has the potential to rewrite trillion-dollar energy markets, but first, startups have to prove their designs will work and won’t be too costly. Neither is easy, especially when ...

A "House of Cards" is a wonderful English phrase that it seems is now primarily associated with a Netflix political drama. However, its original meaning is of a system that is fundamentally unstable.

New research reveals that Earth’s solid inner core is actually in a superionic state, where carbon atoms flow freely through a solid iron lattice. This unusual behavior makes the core soft, matching ...

Thomas Anderson – otherwise known as Neo – is walking up a flight of stairs when he sees a black cat shake itself and walk past a doorway. Then the moment seems to replay before his eyes. Just a touch ...

An MH-60S Knight Hawk helicopter, attached to the ‘Dragonslayers’ of Helicopter Sea Combat Squadron (HSC) 11, conducts a vertical-replenishment with the Nimitz-class aircraft carrier USS Harry S.

Earth may not have to look quite so far for its moon because when our young planet was in a catastrophic collision with a nearby protoplanet, the event might have jettisoned enough planetary debris ...

Abstract: Recommendations for the user to design, establish, and execute real-time based hardware-in-the-loop setups are provided in this document, along with analytical frameworks related to ...

Abstract: The existing distributed cooperative output regulation schemes have designed safe command signals for collisions/obstacle avoidance. However, in large-scale multiagent system (MAS) ...
