Have no fear: the Jolly Green II is finally here.

The Air Force officially took possession of its first two HH-60W Jolly Green II combat rescue helicopters at Moody Air Force Base last week, the service announced.

23rd Wing and 347th Rescue Group leadership took receipt of the new helos after they were flown from Lockheed Martin’s Sikorsky Training Academy in Connecticut to Moody AFB in Georgia by Air Force personnel.

There is a physical and electrical disconnect between the world of electronics and the world of biology. Electronics tend to be rigid, operate using electrons, and are inherently two-dimensional. The brain, as a basis for comparison, is soft, operates using ions, and is three-dimensional. Researchers have therefore been looking to find different routes to create biocompatible devices that work well in wet environments like biological systems. In an exiting new development, researchers from North Carolina State University have fabricated a memory device that is soft, entirely based on liquid-based matter, and functions well in wet environments — opening the door to a new generation of biocompatible electronic devices.

Could molten salt reactors might just turn nuclear power into the greenest energy source on the planet?

At high concentrations, reactive oxygen species—known as oxidants—are harmful to cells in all organisms and have been linked to aging. But a study from Chalmers University of Technology, Sweden, has now shown that low levels of the oxidant hydrogen peroxide can stimulate an enzyme that helps slow down the aging of yeast cells.

One benefit of antioxidants, such as vitamins C and E, is that they neutralize reactive oxygen species —known as oxidants—which may otherwise react with important molecules in the body and destroy their biological functions. Larger amounts of oxidants can cause serious damage to DNA, cell membranes and proteins for example. Our cells have therefore developed powerful defense mechanisms to get rid of these oxidants, which are formed in our normal metabolism.

It was previously believed that oxidants were only harmful, but recently, scientists have begun to understand that they also have positive functions. Now, the new research from Chalmers University of Technology shows that the well-known oxidant hydrogen peroxide can actually slow down the aging of yeast cells. Hydrogen peroxide is a chemical used for hair and tooth whitening, among other things. It is also one of the metabolically produced oxidants that is harmful at higher concentrations.

Sony wants a bigger piece of the drone market. Today, the Japanese giant unveiled a project called Airpeak, which will “support the creativity of video creators to the fullest extent possible,” according to a cryptic press release. That makes it sound like Sony wants to take on consumer-focused drone makers such as DJI, Parrot and Skydio. Which makes a lot of sense, given Sony’s expertise in the compact and full-frame mirrorless camera markets. If you’re a vlogger or independent filmmaker that already uses Sony gear, you might be tempted by a drone with similar technology. If nothing else, it would make it easier to color correct and combine footage.

In the press release, though, Sony notes how drones have led to “workflow efficiency and energy savings in the industrial sector.” It adds: “Sony has assigned the ‘Airpeak’ brand to reflect its aspiration to contribute to the further evolvement and the creation of the unprecedented value through its imaging and sensing technology as well as 3R technologies (Reality, Real-time and Remote) in the drone area.” So it a consumer or enterprise play? We’re hoping its the former. The company already has Aerosense — a business-focused drone collaboration with ZMP — which specializes in surveying, capturing live events and creating maps from drone imagery.

What rights does a robot have? If our machines become intelligent in the science-fiction way, that’s likely to become a complicated question — and the humans who nurture those robots just might take their side.

Ted Chiang, a science-fiction author of growing renown with long-lasting connections to Seattle’s tech community, doesn’t back away from such questions. They spark the thought experiments that generate award-winning novellas like “The Lifecycle of Software Objects,” and inspire Hollywood movies like “Arrival.”

“Anything you take from Earth to the moon is an added weight that you don’t want to carry, so if you can make these materials in situ it saves you a lot of time, effort and money,” said Ian Mellor, the managing director of Metalysis, which is based in Sheffield.

Analyses of rocks brought back from the moon reveal that oxygen makes up about 45% of the material by weight. The remainder is largely iron, aluminium and silicon. In work published this year, scientists at Metalysis and the University of Glasgow found they could extract 96% of the oxygen from simulated lunar soil, leaving useful metal alloy powders behind.

NASA and other space agencies are in advanced preparations to return to the moon, this time to establish a permanent lunar base, or “moon village” where nations will operate alongside private companies on critical technologies such as life support, habitat construction, energy generation and food and materials production.
