If we take the Moon’s current rate of recession and project it back in time, we end up with a collision between the Earth and the Moon around 1.5 billion years ago. However, the Moon was formed around 4.5 billion years ago, meaning that the current recession rate is a poor guide for the past.

Along with our fellow researchers from Utrecht University and the University of Geneva, we have been using a combination of techniques to try and gain information on our solar system’s distant past.

We recently discovered the perfect place to uncover the long-term history of our receding Moon. And it’s not from studying the Moon itself, but from reading signals in ancient layers of rock on Earth.

From a platypus to a blue whale, all living mammals today are descended from a common ancestor that existed some 180 million years ago. Although we don’t know a lot about this animal, a global team of experts has recently computationally reconstructed the organization of its genome. The findings were recently published in the journal Proceedings of the National Academy of Sciences.

“Our results have important implications for understanding the evolution of mammals and for conservation efforts,” said Harris Lewin, distinguished professor of evolution and ecology at the University of California, Davis, and senior author on the paper.

The researchers used high-quality genome sequences from 32 living species, spanning 23 of the 26 known mammalian orders. Humans and chimpanzees were among these species, as were wombats and rabbits, manatees, domestic cattle, rhinos, bats, and pangolins. The chicken and Chinese alligator genomes were also used as comparison groups in the analysis. Some of these genomes are being produced as part of the Earth BioGenome Project and other large-scale biodiversity genome sequencing initiatives. Lewin is the chair of the Earth BioGenome Project’s Working Group.

Many observers were disappointed with the recent demo of the AI-enabled “Optimus” robot at Tesla’s AI Day. One reviewer cleverly titled his article “Sub-Optimus.” However, these views actually miss the point. Whatever else may be said of Elon Musk, he is a genius at sensing timing and opportunity, applying technology and providing the necessary resources.

The quality and enthusiasm of the engineering team suggest Optimus could succeed, even if it takes longer than the estimate of 3 to 5 years for full production. If successful, Optimus could bring personal robots into the mainstream within a decade.

A new technology that incorporates flexible fiber sensors into shoes has been developed by the National Nanotechnology Research Center (UNAM) at Bilkent University and is able to identify a number of health issues, including Parkinson’s disease and gait disorders.

Project manager Mustafa Ordu, who specialized in the production and characterization of fiber cables that can generate electricity for wearable devices, explained that the technology developed at UNAM is loaded with smart sensors that can monitor body movements and determine issues and diseases, with the potential to diagnose many health problems.

Further explaining the cutting-edge technology, he said that it can be woven into body wear or incorporated into footwear since by knitting these cables together like a type of threaded fabric, they can be incorporated into clothing as fibers. “This is what makes our team stand out among the existing laboratories in the world; we make smart sensors with flexible fiber and two-dimensional materials,” said Ordu.

This week, in-space refueling company Orbit Fab won a $13.3 million USSF contract to gas up geostationary (GEO) military satellites starting in 2025. Under the four-year contract, which was first reported by Bloomberg, the Colorado-based space startup will deliver hydrazine propellant to at least one Space Force satellite in GEO.

If you build it, they will come

Jeremy Schiel, cofounder and chief development officer of Orbit Fab, says he expects the Defense Department’s buy-in to boost the company’s credibility on the commercial market.
