A breakthrough that builds on the effects observed in the famous “double slit” experiment could allow physicists a greater ability to observe quantum effects within gravitational fields, according to new research published online.

A team of Italian scientists says they have successfully conducted neutron interferometry using more than one silicon crystal in a physics first that once seemed impossible, based on past attempts.

Inspired by the map makers of the 20th Century, Imperial researchers have demonstrated a new way to identify copyright holders’ work in LLMs.

The technique was presented at the International Conference on Machine Learning in Vienna this week, and is detailed in this preprint on the arXiv server.

Generative AI is taking the world by storm, already transforming the day-to-day lives of millions of people.

SpaceX is targeting Sunday, August 4 for a Falcon 9 launch of 23 Starlink satellites to low-Earth orbit from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California. Liftoff is targeted for 12:24 a.m. PT, with backup opportunities available until 3:52 a.m. PT. If needed, additional opportunities are also available on Monday, August 5 starting at 12:24 a.m. ET.

SpaceX has unveiled the Raptor 3 engine, marking significant advancements in thrust, specific impulse, and mass efficiency compared to previous versions. The Raptor 3 boasts a thrust of 280 tf, a specific impulse of 350s, and an engine mass of 1,525 kg. The SpaceX Raptor 3 engine has potential to exceed 300 tons of thrust in future iterations, emphasizing ongoing efforts to improve efficiency.

Raptor 3 is 36% lighter than Raptor 1. It has 51% more thrust at sea level versus raptor 1. Raptor 3 is 7% lighter than Raptor 2. It has 21% more thrust at sea level versus raptor 2. Elon Musk indicates that Raptor could get another 8–10% more thrust.

Raptor 3 has 2.75 million newtons of thrust versus 2.26 million newtons for the Raptor 2. 33 Raptor 3 engines would provide 90.75 million newtons of thrust for a 33 engine super heavy booster. 35 Raptor 3 engines would provide 96.3 million newtons of thrust for a 35 engine super heavy booster.

Chevron Corp. announced on Friday that it will also move its headquarters from California to Texas, just weeks after Elon Musk announced that SpaceX and X were fleeing for the Lone Star State.

The news came as the company reported its second-quarter earnings on Friday, which fell far short of profit expectations.

According to the company, Chevron’s headquarters will move from San Ramon, California, to Houston, Texas.

An analysis of how rhinoceros beetles deploy and retract their hindwings shows that the process is passive, requiring no muscular activity. The findings, reported in Nature, could help improve the design of flying micromachines.

Among all flying insects, beetles demonstrate the most complex wing mechanisms, involving two sets of wings: a pair of hardened forewings called elytra and a set of delicate membranous hindwings. Although extensive research exists on the origami-like folds of their wings, little is known about how they deploy and retract their hindwings.
