Did you hear that #physicists simulated a baby #wormhole in a lab? Well, it’s even more true that #StringTheory and #ExtraDimensions were discovered in the ’60s. Think I’m joking? I’m not. To learn what’s true/false in the wormhole story, read this first.
Researchers used deep reinforcement learning to steer atoms into a lattice shape, with a view to building new materials or nanodevices.
In a very cold vacuum chamber, single atoms of silver form a star-like lattice. The precise formation is not accidental, and it wasn’t constructed directly by human hands either. Researchers used a kind of artificial intelligence called deep reinforcement learning to steer the atoms, each a fraction of a nanometer in size, into the lattice shape. The process is similar to moving marbles around a Chinese checkers board, but with very tiny tweezers grabbing and dragging each atom into place.
The main application for deep reinforcement learning is in robotics, says postdoctoral researcher I-Ju Chen. “We’re also building robotic arms with deep learning, but for moving atoms,” she explains. “Reinforcement learning is successful in things like playing chess or video games, but we’ve applied it to solve technical problems at the nanoscale.”
It’s claimed to have been created following calls made by Chinese authorities for the independent development of cutting-edge technology.
In East China’s Fujian Province, a huge offshore wind turbine with the world’s largest per-unit capacity has come off the assembly line, according to China’s China Three Gorges Corporation (CTG). According to CTG, the 16-megawatt wind turbine boasts the world’s longest impeller diameter of 827-foot (252 meters), the lightest per megawatt weight, and a 480-foot (146-meter) hub, which is equivalent to the height of a 50-story structure.

Meta staff has mulled over potentially building a rival app to Twitter. But, would it work?
A recent article in The New York Times claims that Meta is trying to make money off of Elon Musk’s messy attempt to take over Twitter. According to the publisher, their plan is to potentially build a competitor application for Twitter to attempt to muscle in on the platform’s unrivaled dominance.
The Times said that in November, Facebook and Instagram, employees met virtually to develop ideas for a text-based app that could compete with Twitter.
According to The Times, a Meta employee stated in a post that “Twitter is in crisis and Meta needs its mojo back.”
“We are on the path to creating the change we seek.”
Israeli-based company Believer Meats is commencing its first U.S. commercial facility in North Carolina. Located in Wilson, the company’s new spurt will be the biggest and largest cultivated production facility established so far, covering a site of 200,000-square-foot (18580,608 m2).
Believer Meats is one of the largest companies producing 3D-printed lab-grown meat with non-GMO animal cells. The company is cruelty-free and very respectful of the ecological environment. With the 10,000 metric tons of cultivated meat capacity, Believer Meats seems to be about to change the industry.
Planet 55 Cnc e, also known as “Janssen”, orbits so close to its sun that a year is shorter than an Earth day.
Scientists shed new light on planet 55 Cnc e, known by some as the “hell planet”, revealing how it became so fiery.
That wasn’t always the case, though. New, exact measurements of a planet roughly 40 light-years away from Earth allowed scientists to gain further insight into the way planets can turn into fiery hellscapes over many millennia, as per a press statement.

And it’s all thanks to the death of an Earth-sized star as well as a few ‘innocent bystanders.’
The stunning Southern Ring Nebula, NGC 3,132, was created when a star expelled most of its gas 2,500 years ago. It was selected as one of the first five image packages from the James Webb Space Telescope (JWST).
The research opens the door for future JWST nebula investigations.

Until now, it was thought they came from massive star collapses.
Astrophysicists around the world may be shocked to learn that long gamma-ray bursts (GRBs) do not solely come from the collapse of massive stars. A new study by astrophysicists at Northwestern University upends the long-standing belief, uncovering new evidence that at least some long GRBs can result from neutron star mergers, which were previously believed to produce only short GRBs, the university’s publication reported.
It all began in December 2021 when the team detected a 50-second-long GRB (any GRB longer than 2 seconds is considered ‘long’).

Google today announced two new performance settings in its Chrome browser: Memory Saver and Energy Saver.
Modern browsers eat up a lot of memory and while that’s not a problem if you have 32GB of RAM, Chrome using multiple gigabytes of your memory can quickly slow your machine down if you’re on a machine with lower specs. The Memory Saver mode promises to reduce Chrome’s memory usage by up to 30% by putting inactive tabs to sleep. The tabs will simply reload when you need them again. The Energy Saver mode, meanwhile, limits background activity and visual effects for sites with animations and videos when your laptop’s battery level drops below 20%.
‘I almost died on the way out,’ said the six-foot-two tall archeologist who lost 25 kgs to enter a 17.5-centimeter cave.
Researchers claim to have discovered new evidence of extinct human species who lived in the underground caves of modern-day South Africa.
“We have massive evidence. It’s everywhere,” said Berger, who reported the findings in a press release and a Carnegie Science lecture at the Martin Luther King Jr.
