Summary: Astrocytes help transition the brain from a highly plastic state to one that is more stable.

Researchers exploring the developing central nervous system of fruit flies have identified nonelectrical cells that transition the brain from highly plastic into a less moldable, mature state.
Writer-director Neil Burger is well known for his provocative cinematic projects, most notably 2006’s period-set magician movie “The Illusionist,” 2011’s psychological thriller “Limitless,” and a trio of “Divergent” films adapted from author Veronica Roth’s young adult sci-fi novels.
Now Burger has his eyes fixed on the stars with his new science fiction adventure flick, “Voyagers,” which revolves around the perils inside a generation spaceship carrying 30 home-grown candidates on a one-way mission to settle an exoplanet 86 years from Earth.
Push that envelope, Molly Cobb.

I found your rocket … Kyle Foreman, a spokesman for the sheriff’s office, told GeekWire that the property owner left a message reporting the debris. “The sheriff’s office checked it out on Monday, and SpaceX staff came over on Tuesday and retrieved it,” Foreman said. SpaceX has yet to detail precisely what went wrong with the Falcon 9 rocket’s second stage, such that it failed to de-orbit in a controlled manner over the ocean. Fortunately, no one on the ground was injured. (submitted by Ken the Bin)
Brazilian launch site stirs controversy. The Brazilian government is committed to further developing the Alc ntara Launch Center on the country’s north Atlantic coast, near the equator. However, the region is also home to Afro-Brazilian residents of settlements first established by escaped slaves. These settlements are known as Quilombola communities. The Washington Post recently did a deep dive into the controversy, examining how eviction of these communities would affect local residents. The newspaper found that the spaceport expansion could displace nearly 2100 people from Quilombola communities.
Brazil’s polarizing dilemma … Marcos Pontes, head of the Brazilian Ministry of Science, Technology and Innovation, said there are no plans to relocate families “right now.” And if the time comes to remove people, he predicted, they will go willingly. “They are going to see development coming in, real development,” he said. “All of the resistance, that is going to be gradually disappearing.” This seems unlikely. The clash is the distillation of one of Brazil’s most urgent and polarizing dramas, the publication says. What is more important: developing a vast country with unrealized potential and a lagging economy? Or protecting some of its most vulnerable communities?
If the bill passes, it would “unfairly shift the cost of ancillary electric services exclusively onto renewable generators rather than all the beneficiaries,” according to a letter written by the Partnership for Renewable Energy Finance (PREF), an industry group, and signed by Amazon, Berkshire Hathaway Energy, Goldman Sachs, and a number of other firms.
Bill would “directly assign” grid stability costs to renewable power providers.
Researchers at the University of California, Los Angeles (UCLA), have solved a 100-year-old problem in science – capturing the 3D structure of an amorphous solid, in this case metallic glass.
Elon Musk finally got to show off his monkey.
Neuralink, a company founded by Musk that is developing artificial-intelligence-powered microchips to go in people’s brains, released a video Thursday appearing to show a macaque using the tech to play video games, including “Pong.”
A few weeks back we brought word that Reddit users [derekcz] and [Xerbot] had managed to receive the 2232.5 MHz telemetry downlink from a Falcon 9 upper stage and pull out some interesting plain-text strings. With further software fiddling, the vehicle’s video streams were decoded, resulting in some absolutely breathtaking shots of the rocket and its payload from low Earth orbit.
Unfortunately, it looks like those heady days are now over, as [derekcz] reports the downlink from the latest Falcon 9 mission was nothing but intelligible noise. Since the hardware and software haven’t changed on his side, the only logical conclusion is that SpaceX wasn’t too happy about radio amateurs listening in on their rocket and decided to employ some form of encryption.

About a year ago, Honeywell announced that it had entered the quantum computing race with a technology that was different from anything else on the market. The company claimed that because the performance of its qubits was so superior to those of its competitors, its computer could do better on a key quantum computing benchmark than quantum computers with far more qubits.
Now, roughly a year later, the company finally released a paper describing the feat in detail. But in the meantime, the competitive landscape has shifted considerably.
