Texas’ Venus Aerospace Opens New Rocket Propulsion Test Stand

Venus Aerospace has opened a new propulsion test stand at the Houston Spaceport to expand testing of its rotating detonation rocket engine. Supported by the Texas Space Commission, the facility allows Venus to perform higher-thrust and longer-duration tests. The company says the added capacity will help advance its propulsion systems toward future defense and space applications.

Artistic reconstruction of the extinct Miracinonyx trumani, an ancient North American cat related to modern pumas.

Scientists Find America’s ‘Cheetah’ Was Actually a Puma Relative

A new study has changed what scientists know about the extinct “American cheetah,” Miracinonyx trumani. DNA evidence shows that the animal was more closely related to modern pumas than cheetahs. Researchers also found that northern populations living in the Yukon ate almost exclusively fish, showing how the predator adapted to very different environments.

STREAMLINE uses artificial intelligence and supercomputing to model interacting particles inside atomic nuclei.

Argonne Uses AI to Solve a Tough Nuclear Physics Problem

Argonne National Laboratory is part of STREAMLINE, a research project using AI and supercomputers to tackle a major nuclear physics problem. Researchers are training neural networks to model the complex behavior of protons and neutrons inside atomic nuclei. The approach can scale to about 100 interacting particles, compared with roughly a dozen for some earlier methods, potentially enabling more realistic nuclear simulations.
