How deep is the lunar regolith and megaregolith, the latter of which consists of the cracked lunar crust layers resulting from billions of years of impact craters? This is what the Synthetic Pulse Artemis Radar for Crustal Imaging (SPARCI, pronounced “sparky”) instrument hopes to address as the Southwest Research Institute (SwRI) was recently awarded a 3-year, $2,041,000 grant from NASA’s Development and Advancement of Lunar Instrumentation (DALI) program as part of advancing lunar exploration technologies.

“Learning more about the lunar megaregolith will help us gain a wider understanding of the Moon’s formation and that of similar bodies with thin, sparse atmospheres,” said Dr. David Stillman, who is a geophysicist at SwRI and SPARCI’s principal investigator. “If we are able to pinpoint exactly where this layer begins, we can use that to create more accurate formation and evolution models.”

Long-wavelength infrared (LWIR) imaging holds critical significance across many applications, from consumer electronics to defense and national security. It finds applications in night vision, remote sensing, and long-range imaging. However, the conventional refractive lenses employed in these imaging systems are bulky and heavy, which is undesirable for almost all applications. Compounding this issue is the fact that many LWIR refractive lenses are crafted from expensive and limited-supply materials, such as germanium.

The blockbuster weight loss drug semaglutide can cut the progression of diabetic kidney disease, according to its manufacturer Novo Nordisk, adding to growing evidence that the medication has beneficial effects beyond treating Type 2 Diabetes and obesity.

Semaglutide — which is marketed under the name Ozempic for diabetes treatment and Wegovy for weight loss — managed to also reduce death from kidney disease and cardiovascular issues by 24 percent versus a placebo.

The results came from a Novo Nordisk clinical trial that had 3,533 participants with both diabetes and chronic kidney disease. High blood sugar from diabetes can damage kidneys and ultimately lead to chronic kidney disease, in which the organ has trouble filtering toxins from the blood.

More than half a billion people worldwide are affected by type 2 diabetes, and yet researchers still don’t know what’s behind the condition’s breakdown in insulin functionality.

Researchers from Case Western Reserve University in the US have now pulled back the molecular curtain and figured out why insulin, the hormone that maintains stable blood sugar, often stops working at its full effect.

The principal investigator, Jonathan Stamler, is widely acclaimed for the discovery of S-nitrosylation, which is the process that turns nitric oxide (NO) into a ubiquitous messenger molecule capable of sharing information between cells. It’s kind of like putting a stamp on a letter.

Apple acquired Canada-based company DarwinAI earlier this year to build out its AI team, reports Bloomberg. DarwinAI created AI technology for inspecting components during the manufacturing process, and it also had a focus on making smaller and more efficient AI systems.

DarwinAI’s website and social media accounts have been taken offline following Apple’s purchase. Dozens of former DarwinAI companies have now joined Apple’s artificial intelligence division. AI researcher Alexander Wong, who helped build DarwinAI, is now a director in Apple’s AI group.
