Don’t mean to alarm you, but robots are now able to reproduce. Terrific.

Two operators including Chinese internet search giant Baidu have been given the green light to start charging passengers to use their autonomous taxis in Beijing.

Baidu and Pony AI became the first companies to be granted licences by mainland Chinese authorities to launch their driverless cab services commercially following successful trial periods.

On Thursday, the Beijing High-level Automated Driving Demonstration Area gave permission for Baidu and Pony AI to charge fees for their so-called robotaxis in a designated area of the capital covering 60 square kilometres.

A UK company with lofty aspirations around sustainable space travel has test-fired a rocket engine powered in part by plastic waste. Pulsar Fusion’s hybrid rocket engine is part of an ambitious journey that also involves the development of nuclear fusion technology for high-speed propulsion, which could cut travel times to Mars in half.

The idea of incorporating recycled plastic waste into hybrid rocket fuels is something we have seen explored before. Virgin Galactic flirted with the idea back in 2014 through the use of a rocket powered by a fuel based on a class of thermoset plastics, though this was swiftly abandoned after a failed test flight. Scottish company Skyrora is another outfit working on such a technology, having successfully tested out its Ecosene fuel made from converted plastic waste.

Microsoft has released Windows 11 build 22504.1010 (KB5008697) to Insiders in the Dev Channel. It does not add anything new and is a cumulative update to test the servicing pipeline.

Gen. David Thompson, vice chief of space operations for the US Space Force, said Saturday China is developing its space capabilities at “twice the rate” of the US.

On a panel of US space experts and leaders speaking at the Reagan National Defense Forum in a panel moderated by CNN’s Kristin Fisher, Gen. Thompson warned China could overtake the US in space capabilities by the end of the decade.

“The fact, that in essence, on average, they are building and fielding and updating their space capabilities at twice the rate we are means that very soon, if we don’t start accelerating our development and delivery capabilities, they will exceed us,” Gen. Thompson said, adding, “2030 is not an unreasonable estimate.”

Black holes are one of the greatest mysteries of the universe—for example, a black hole with the mass of our sun has a radius of only 3 kilometers. Black holes in orbit around each other emit gravitational radiation—oscillations of space and time predicted by Albert Einstein in 1916. This causes the orbit to become faster and tighter, and eventually, the black holes merge in a final burst of radiation. These gravitational waves propagate through the universe at the speed of light, and are detected by observatories in the U.S. (LIGO) and Italy (Virgo). Scientists compare the data collected by the observatories against theoretical predictions to estimate the properties of the source, including how large the black holes are and how fast they are spinning. Currently, this procedure takes at least hours, often months.

An interdisciplinary team of researchers from the Max Planck Institute for Intelligent Systems (MPI-IS) in Tübingen and the Max Planck Institute for Gravitational Physics (Albert Einstein Institute/AEI) in Potsdam is using state-of-the-art machine learning methods to speed up this process. They developed an algorithm using a deep neural network, a complex computer code built from a sequence of simpler operations, inspired by the human brain. Within seconds, the system infers all properties of the binary black-hole source. Their research results are published today in Physical Review Letters.

“Our method can make very accurate statements in a few seconds about how big and massive the two black holes were that generated the gravitational waves when they merged. How fast do the black holes rotate, how far away are they from Earth and from which direction is the gravitational wave coming? We can deduce all this from the observed data and even make statements about the accuracy of this calculation,” explains Maximilian Dax, first author of the study Real-Time Gravitational Wave Science with Neural Posterior Estimation and Ph.D. student in the Empirical Inference Department at MPI-IS.
