The test is a stepping stone to achieving carbon neutrality by 2050.

In what can be considered a promising first step towards transforming the aviation industry to become carbon-neutral, a project led by Rolls Royce and easyJet has successfully tested a modern-day jet engine that runs solely on hydrogen.

The prototype for the experiment, which was conducted at a test facility at the Ministry of Defence Boscombe Down, U.K., was a commonly-used Rolls-Royce AE-2100A regional aircraft engine. The turbine was supplied with ‘green’ hydrogen, which was made by splitting water into its constituent components at European Marine Energy Centre in the Orkney Islands, U.K.

“We are pushing the boundaries to discover the zero carbon possibilities of hydrogen, which could help reshape the future of flight,” Grazia Vittadini, chief technology officer of Rolls-Royce, said in a statement.

NASA said Orion is the safest spacecraft in the NASA fleet.

The technological advancements in imaging over the past 20 years are really paying off in space. From Hubble Space Telescope to James Webb, the Perseverance Mars Rover, and now NASA’s Orion spacecraft, a stream of amazing images from space parade before us.

Images are just the beginning

The Orion images capture what it’s like to see Earth from a distance, a great distance. Even the best cameras need to be enhanced for this type of imaging, and Orion is up to that task, and the task of bringing humans back to the Moon.

The absence of the 21-centimeter hydrogen line allowed scientists to determine specific properties of the earliest galaxies in the universe.

An international group of astronomers, led by scientists at the University of Cambridge, just shed new light on the cosmic dawn of the universe, a press statement reveals.

The cosmic dawn is a very early period of the universe, during which the first stars and galaxies formed. The researchers used data from India’s SARAS3 radio telescope to analyze this period of the cosmos and determine mass and energy output limits for the first stars and galaxies.

The ASO-S observatory, which launched in early October, captured an image of a solar flare eruption.

China’s recently launched Advanced Space-based Solar Observatory (ASO-S) beamed its first image back to Earth, a report from Space.com reveals. The new image shows an M-Class flare erupting on the Sun.

China’s ASO-S solar observatory launched to orbit aboard one of the China Aerospace and Technology Corporation’s (CASC’s) Long March-2C rockets on October 9. The country’s first dedicated solar observatory is positioned in a sun-synchronous orbit around Earth, flying at an altitude of approximately 430 miles (700 km).

This is “the first time that lower mantle minerals have ever been observed in nature.”

Researchers claim they have discovered a rare mineral that comes directly from Earth’s lower mantle-the region between the planet’s core and crust — in a new study published in Science.

However, thanks to a diamond-in which it was entrapped — the new mineral dubbed ‘davemaoite,’ managed to make the improbable voyage from at least 412 meters within the lower mantle.

Within a 12 to 18 months time frame.

Twitter owner Elon Musk took to the social media platform on Sunday to share some very ambitious plans. “I think I see a path to Twitter exceeding a billion monthly users in 12 to 18 months,” he said.

Several impressive increases.

Tesla Semi carried 81,000 pounds for 500 miles on a single charge.

Just a few days before Tesla begins shipping the truck, Elon Musk has verified that Tesla Semi, the company’s Class 8 semi-truck, has successfully completed a crucial voyage.

Although there is no reason to question the outcome, it would be interesting to learn more about speed and energy usage. We are pretty interested in seeing some impartial vehicle tests.

Tesla.

“Houston, we have a new record.”

NASA’s Artemis I Orion capsule broke a new spaceflight record. The uncrewed Orion reached a distance from Earth of 249,666 miles (from 401,798 kilometers) on Saturday, November 26, at 10:17 am. ET, meaning it surpassed a record set by Apollo 13 in 1970 for the furthest distance traveled from Earth by a spacecraft designed to carry humans.

NASA’s Orion spacecraft broke a massive record.

The previous record was set by Apollo 13’s crewed Odyssey command module in 1970 when it traveled 248,655 miles (400,171 kilometers) from Earth. Orion crossed that threshold at 8:40 am. ET on November 26 before going on to extend the record.

Apple cut one of the few ways to avoid censorship in China, airdrops.

Apple’s recent iOS update quietly, and completely unannounced, stopped offering the AirDrop service to Chinese phones and tablets. Airdrops are a file transfer service that sends specific files, directly between phones, without the need for a network. In the wave of anti-government protests larger than ever before, protesters are having to communicate without the use of a crucial tool: AirDrops.

AirDrop, a file-sharing feature on Apple iOS devices, has aided dissent in many authoritarian countries. The phones form a local network of devices, that are independent of any external sources.

The neuroscience of perception has recently been revolutionized with an integrative modeling approach in which computation, brain function, and behavior are linked across many datasets and many computational models. By revealing trends across models, this approach yields novel insights into cognitive and neural mechanisms in the target domain. We here present a systematic study taking this approach to higher-level cognition: human language processing, our species’ signature cognitive skill. We find that the most powerful “transformer” models predict nearly 100% of explainable variance in neural responses to sentences and generalize across different datasets and imaging modalities (functional MRI and electrocorticography). Models’ neural fits (“brain score”) and fits to behavioral responses are both strongly correlated with model accuracy on the next-word prediction task (but not other language tasks). Model architecture appears to substantially contribute to neural fit. These results provide computationally explicit evidence that predictive processing fundamentally shapes the language comprehension mechanisms in the human brain.
