Artificial Motors Mimic Muscle Proteins for Innovation

The recent advancements in nanotechnology have paved the way for the development of artificial motors that closely replicate the natural mechanisms inherent in biological systems. A groundbreaking study from The University of Manchester, in collaboration with the University of Strasbourg, has introduced artificial rotary motors capable of mimicking muscle proteins. This innovation marks a significant step in understanding molecular machines and could have profound implications across various fields, including medicine, energy, and nanotechnology.

Wolf Moon Engulfs Mars

Explanation: Does the Moon ever engulf Mars? Yes, but only in the sense that it moves in front, which happens on rare occasions. This happened just yesterday, though, as seen from some locations in North America and western Africa. This occultation was notable not only because the Moon was a fully lit Wolf Moon, but because Mars was near its largest and brightest, moving to opposition -- the closest to the Earth in its orbit -- only tomorrow. The engulfing, more formally called an occultation, typically lasts about an hour. The featured image was taken from near Chicago, Illinois, USA just as Earth's largest satellite was angularly moving away from the much more distant red planet. Our Moon occasionally moves in front of all of the Solar System's planets. Given the temporary alignment of orbital planes, the next time our Moon eclipses Mars will be a relatively soon February 9.

Ancient Martian Water Bodies Indicated by Wave Ripples

Follow for Fediverse Science, Astronomy, and Health News.

The research associated with this finding was published in the journal Science Advances and involved a variety of scientists affiliated with the California Institute of Technology, including John Grotzinger—Harold Brown Professor of Geology—and Michael Lamb, Professor of Geology. They employed the data collected by NASA's Curiosity rover which discovered these ripple formations as it traversed the Gale Crater region in 2022.

According to postdoctoral scholar Claire Mondro, the formation of these ripples could only have occurred in open-water conditions interacting energetically with the atmosphere: "The shape of the ripples could only have been formed under water that was open to the atmosphere and acted upon by wind." This is an important realization that suggests a stable environmental scenario existed on ancient Mars.

An ancient 3-star system gave this 'blue lurker' star a turbo boost, scientists find

"We have by and large been ignoring triples in models and simulations — we're just starting to understand how these types of systems evolve."

ESA's XMM-Newton spacecraft has detected an unprecedented X-ray signal coming from the very edge of a supermassive black hole.

This defies how we thought matter falls into black holes, and points to a potential source of gravitational waves for ESA’s future LISA mission.

Green Tea Protects Brain Health in Older Adults

Research conducted by the Kanazawa University Graduate School of Medical Sciences reveals a significant correlation between the consumption of green tea and a reduction in cerebral white matter lesions among older adults who do not have dementia. The findings suggest that ingesting three or more cups of green tea daily may confer protective benefits for brain health, while similar effects were not noted for coffee consumption.

Stem cells reverse woman’s diabetes — a world first

A 25-year-old woman with type 1 diabetes started producing her own insulin less than three months after receiving a transplant of reprogrammed stem cells1. She is the first person with the disease to be treated using cells that were extracted from her own body.

“I can eat sugar now,” said the woman, who lives in Tianjing, on a call with Nature. It has been more than a year since the transplant, and, she says, “I enjoy eating everything — especially hotpot.” The woman asked to remain anonymous to protect her privacy.

James Shapiro, a transplant surgeon and researcher at the University of Alberta in Edmonton, Canada, says the results of the surgery are stunning. “They’ve completely reversed diabetes in the patient, who was requiring substantial amounts of insulin beforehand.”

Check Out the Stunning New Images of Jupiter From NASA's Juno Spacecraft

NASA’s Juno spacecraft has just released stunning images of Jupiter, captured during its 66th flyby of the largest and oldest planet in our solar system.

The Juno mission has been studying the Jovian system—Jupiter, along with its rings and many moons—to learn about the giant planet’s formation and evolution with the hope that it might shed light on the development of the entire solar system, per a NASA statement. The solar-powered spacecraft launched from Cape Canaveral, Florida, in August 2011 and reached Jupiter in July 2016.

“Jupiter is the Rosetta Stone of our solar system. Juno is going there as our emissary—to interpret what Jupiter has to say,” Scott Bolton, Juno principal investigator and associate vice president of the Southwest Research Institute’s Science and Engineering Division, says in the statement.
