Nitinol, a “memory” metal that can remember its original shape when heated, is an industrial gem that will play a key role in NASA’s next mission to Mars.

Implementing artificial intelligence at the edge can not only reduce latency and networking costs but also improve security and unlock the power of distributed intelligence.

The Expedition 64 crew continued researching how microgravity affects biology aboard the International Space Station today. The orbital residents also conducted vein and eye checks and prepared for three new crew members due in early April.
NASA Flight Engineer Shannon Walker joined Russian cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov for vein and eye scans on Thursday. Japan Aerospace Exploration Agency astronaut Soichi Noguchi led the effort scanning veins in the trio’s neck, clavicle and shoulder areas using the Ultrasound 2 device in the morning. In the afternoon, Noguchi examined Walker’s eyes using the orbiting lab’s optical coherence tomography gear.
Walker also assisted fellow Flight Engineer Kate Rubins of NASA setting up samples of tiny worms for viewing in a microscope. Rubins captured video of the microscopic worms wriggling around to learn how microgravity affects genetic expression and muscle function. Insights from the Micro-16 study may benefit human health on and off the Earth.

The mayor of Oakland, California, on Tuesday announced a privately funded program that will give low-income families of color in the city $500 per month with no rules on how they can spend it.
The program is the latest experiment with a “guaranteed income,” the idea that giving low-income individuals a regular, monthly stipend helps ease the stresses of poverty and results in better health and upward economic mobility.”

After two years successfully testing Oakland, California now will expand its basic income to low income residents.

LOS ANGELES — UCLA neuroscientists reported Monday that they have transferred a memory from one animal to another via injections of RNA, a startling result that challenges the widely held view of where and how memories are stored in the brain.
The finding from the lab of David Glanzman hints at the potential for new RNA-based treatments to one day restore lost memories and, if correct, could shake up the field of memory and learning.
“It’s pretty shocking,” said Dr. Todd Sacktor, a neurologist and memory researcher at SUNY Downstate Medical Center in Brooklyn, N.Y. “The big picture is we’re working out the basic alphabet of how memories are stored for the first time.” He was not involved in the research, which was published in eNeuro, the online journal of the Society for Neuroscience.
Many scientists are expected to view the research more cautiously. The work is in snails, animals that have proven a powerful model organism for neuroscience but whose simple brains work far differently than those of humans. The experiments will need to be replicated, including in animals with more complex brains. And the results fly in the face of a massive amount of evidence supporting the deeply entrenched idea that memories are stored through changes in the strength of connections, or synapses, between neurons.
The world’s most powerful laser is scheduled for a slate of experiments next year.
The laser, in Romania, managed to fire at 10 petawatts — that’s one-tenth the power of all the sunlight that reaches Earth concentrated into a single laser beam — during a test run in March. Now, according to ExtremeTech, the scientists behind it intend to discover new high-energy cancer treatments and simulate supernovas to reveal how the stellar explosions form heavy metals.
The laser is part of the European Union’s Extreme Light Infrastructure project. The hope is that lasers will lead to new medical techniques, a better understanding of how the universe works, and improved nuclear safety.

Musk’s tweet offering guidance on timing for an anticipated increase in Tesla’s market cap has since been deleted, but screenshots were widely shared on Twitter.
The U.S. Securities and Exchange Commission has clashed with Musk and Tesla over the CEO’s unfettered use of Twitter before.
In the third quarter of 2018, Musk faced securities fraud charges from the SEC after he tweeted to his tens of millions of followers then that he was planning to take Tesla private at $420 a share, and had secured funding to do so. Tesla’s stock price jumped more than 6 percent that day.
