Sandia National Laboratories researchers have developed a fundamentally new type of rotary electrical contact. The technology is called Twistact, and it will eliminate the need for expensive rare-earth magnets in large wind turbines.

Sandia is now ready to partner with the energy industry to develop the next generation of direct-drive wind turbines.

Sandia’s Twistact is a novel approach to transmitting electrical current between a stationary and rotating frame, or between two rotating assemblies having different speeds or rotational directions. This method is ideal for use in wind turbines.

The scale of the OpenAI CEO’s chip ambitions requires a vast amount of resources.

New research posits that life originated somewhere in the cosmos — and that it traveled through space on tiny particles of cosmic dust.

This is very cool. I didn’t know that something could hold so much more water than than our Earth. I can see something having more water but trillions of times?

The water is in the form of vapor distributed around a black hole said to be 20 billion times more massive than the sun.

Scientists have proposed an intriguing theory on our universe’s rapid expansion.

For years, scientists have grappled with the enigma of the universe expanding rapidly.

Observations like the redshift of galaxies and the cosmic microwave background hint at this cosmic phenomenon, but a complete explanation remains elusive.

Doug Philippone, a venture capitalist, has explained to a media house the importance of lizard-like robots for the future of US Armed Forces like the United States Navy.

Wall climbing robots are used for non-destructive testing inspections of tanks, boilers, pressure vessels, piping, and more, explains Gecko Robotics. These robots utilize specially designed sensor payloads to inspect wall thickness, pitting, and numerous forms of degradation.

The ADRAS-J satellite, which weighs 150 kilograms (330 pounds), lifted off on top of an Electron rocket from Rocket Lab’s launch site in New Zealand at 9:52 am EST (1452 GMT; 3:52 am local New Zealand time on February 19).

RFID tags are commonly used to verify the authenticity of products, but they have some drawbacks. They are relatively large, expensive, and vulnerable to counterfeiting. A team of MIT engineers has developed a new type of ID tag that overcomes these limitations by using terahertz waves, which are smaller and faster than radio waves.

The new tag is a cryptographic chip several times smaller and cheaper than RFID tags. It also offers improved security, using the unique pattern of metal particles in the glue that attaches the tag to the item as a fingerprint. This way, the authentication system will detect tampering if someone tries to peel off the tag and stick it to a fake item.

Odysseus is one of the first landers to participate in NASA’s Commercial Lunar Payload Services (CLPS) program, which aims to deliver science and technology payloads to the lunar surface using commercial partners. The CLPS program is a key component of NASA’s Artemis program, which plans to establish a sustainable human presence on the moon by the end of the 2020s.

Intuitive Machines successfully transmitted its first IM-1 mission images to Earth on February 16, 2024. The images were captured shortly after separation from @SpaceX’s second stage on Intuitive Machines’ first journey to the Moon under @NASA’s CLPS initiative. pic.twitter.com/9LccL6q5tF — Intuitive Machines (@Int_Machines) February 17, 2024

Odysseus is carrying six NASA experiments and technology demonstrations, along with six private payloads, on its current IM-1 mission. The lander is expected to touch the moon on February 22, near the lunar equator.
