SpaceX has shared dramatic slow-motion footage showing a Raptor engine powering down at the end of a recent test fire.

“Shutdown of a Raptor vacuum engine in slow motion,” SpaceX said in a message accompanying the video (below). It added that the engine’s nozzle “is sized for use by Starship in the Earth’s upper atmosphere and outer space, so operation at sea level and low chamber pressures results in flow separation creating visible rings in the exhaust.”

Microplastics pose a great threat to human health. These tiny plastic debris can enter our bodies through the water we drink and increase the risk of illnesses. They are also an environmental hazard; found even in remote areas like polar ice caps and deep ocean trenches, they endanger aquatic and terrestrial lifeforms.

After months of leaks, OpenAI has apparently fired two researchers who are said to be linked to company secrets going public.

As The Information reports based on insider knowledge, the firm has fired researchers Leopold Aschenbrenner — said to be a close ally of embattled cofounder Ilya Sutskever — and Pavel Izmailov.

Both men had worked on OpenAI’s safety team, per the report, though most recently, Aschenbrenner had been working on its so-called “superalignment” efforts while Izmailov was tasked with researching AI reasoning. We’ve reached out to OpenAI and Microsoft, its major investor, for further context.

By apparently overtraining them, researchers have seen neural networks discover novel solutions to problems.

The BESIII collaboration have reported the observation of an anomalous line shape around ppbar mass threshold in the J/ψ→γ3(π+π-) decay, which indicates the existence of a ppbar bound state. The paper was published online in Physical Review Letters.

Tesla has revealed some of its humanoid robot technology through filings for several new patents related to its Optimus robot program.

A few months ago, Tesla unveiled “Optimus Gen 2”, a new generation of its humanoid robot that should be able to take over repetitive tasks from humans.

The new prototype showed a lot of improvements compared to previously underwhelming versions of the robot, and it gave some credibility to the project.
