In one way or another, the Lunar Gateway has lingered around the periphery of NASA's human exploration program since the Obama administration.

Back then, the elements that eventually coalesced into the Gateway were geared toward a nebulous initiative to capture a small asteroid and reposition it closer to Earth. Under direction from the first Trump administration, NASA ditched the asteroid idea and repackaged the concept to become a mini-space station in orbit around the Moon.

NASA officials justified the Lunar Gateway program by highlighting its utility as a staging point or safe haven for astronauts traveling to and from the surface of the Moon. Crews could launch from Earth and travel to the Moon's vicinity inside NASA's Orion spacecraft, connect with the Gateway, and then float into their lunar lander already docked with the outpost.

Razer, maker of green-hued gaming hardware and accessories, has entered the game-streaming space with its new—but not entirely new—app, PC Remote Play . It's based on very good existing streaming tech and makes connecting a PC to mobile devices fairly simple. It's worth checking out unless you have a hard-and-fast policy about avoiding software "utilities" from RGB-obsessed gaming companies.

That, or you're already using and comfortable with Moonlight . Moonlight and Sunshine are the open source game-streaming client and server that wonderfully picked up where Nvidia's Gamestream left off . PC Remote Play is based on Moonstream's open source code, and Razer has made much of its own version's code available .

You're getting a few small upgrades when using PC Remote Play:

The Li-ion batteries that power everything from smartphones to electric cars are usually packed in rigid, sealed enclosures that prevent stresses from damaging their components and keep air from coming into contact with their flammable and toxic electrolytes. It’s hard to use batteries like this in soft robots or wearables, so a team of scientists at the University California, Berkeley built a flexible, non-toxic, jelly-like battery that could survive bending, twisting, and even cutting with a razor.

While flexible batteries using hydrogel electrolytes have been achieved before, they came with significant drawbacks. “All such batteries could [only] operate [for] a short time, sometimes a few hours, sometimes a few days,” says Liwei Lin, a mechanical engineering professor at UC Berkeley and senior author of the study. The battery built by his team endured 500 complete charge cycles—about as many as the batteries in most smartphones are designed for.

Power in water

“Current-day batteries require a rigid package because the electrolyte they use is explosive, and one of the things we wanted to make was a battery that would be safe to operate without this rigid package,” Lin told Ars. Unfortunately, flexible packaging made of polymers or other stretchable materials can be easily penetrated by air or water, which will react with standard electrolytes, generating lots of heat, potentially resulting in fires and explosions. This is why, back in 2017, scientists started to experiment with quasi-solid-state hydrogel electrolytes.
