An analogue of a tiny, expanding universe has been created out of extremely cold potassium atoms. It could be used to help us understand cosmic phenomena that are exceedingly difficult to directly detect, such as pairs of particles that may be created out of empty space as the universe expands.

Markus Oberthaler at Heidelberg University in Germany and his colleagues cooled more than 20,000 potassium atoms in a vacuum, using lasers to slow them down and lower their temperature to about 60 nanokelvin, or 60 billionths of a degree kelvin above absolute zero.

At this temperature, the atoms formed a cloud about the width of a human hair and, instead of freezing, they became a quantum, fluid-like phase of matter called a Bose-Einstein condensate. Atoms in this phase can be controlled by shining light on them – using a tiny projector, the researchers precisely set the atoms’ density, arrangement in space and the forces they exert on each other.

A Full Moon could cut into some viewing opportunities, but the peak still could bring some bright fireballs.

Elon Musk doesn’t follow the same standards that most entrepreneurs do. He’s different, he likes to be different!

And when you’re different, and you’re not afraid to be, it’s okay to test a cigar (or should I say ‘joint’?) of tobacco mixed with marijuana, on Joe Rogan’s famous podcast. But if you look closely, Elon was just nice (polite) and followed Rogan’s elaborate script. Before trying it, Musk even asked him if it was legal.

Then all those facial expressions of Musk, which photojournalists love to catch, go viral as if he’s there promoting some soft drug or passing abroad that his office at Tesla (or SpaceX) is enveloped in a large cloud of smoke.

Quite the opposite. The expressions themselves spoke for themselves, as if to say, “This is nothing special, Joe. Why do you waste my time with these scenes”? Musk even claimed that weed is not good for productivity at all, but it has nothing against (as I do, by the way).

It holds an enigmatic result regarding connectivity between the hippocampus and other parts of the brain.

Researchers have created the most detailed map ever made of the human brain — specifically the communication links between the hippocampus. This part of the brain is the section that controls memory, particularly long-term and short-term memory, along with spatial memory, a type of memory that allows for the recollection of location. The research team consisted of scientists from the University of Sydney’s Brain and Mind Center in Australia.

“What we’ve created is a highly detailed map of white matter pathways connecting the hippocampus with the rest of the brain. It’s essentially a roadmap of brain regions that directly connect with the hippocampus and support its important role in memory formation,” said Dr. Marshall Dalton, a research fellow in the School of Psychology at the University of Sydney.

The magnetic material emulates learning that occurs in the brain during deep sleep.

Researchers have developed a material that can replicate the way the brain stores information. The material works by copying the synapses of neurons, allowing it to mimic learning that occurs during deep sleep. The team of researchers, from the Universitat Autònoma de Barcelona (UAB), built the magnetic material using a type of computation called neuromorphic computing.

Neuromorphic computing is a computing concept that uses artificial neurons to mimic behavior of the brain and the synaptic functions, or communication signals, of neurons.

All they need is electrical stimulation, and once activated, they re-establish the lost connection between different regions of the spinal cord.

Imagine you are stuck inside a room, you want to get out, but your body is not moving. No matter how hard you try, you are unable to move your body parts. You are not even able to move your finger, how would you feel? Well, that’s what chronic paralysis feels like.

Unfortunately, there is no known permanent cure for this neurological disorder, and this is what makes the situation worse. The physical and mental struggle that a patient with chronic paralysis goes through is unimaginable.

Meta, Twitter employees, and eagles all appear to be in the same boat.

Drone-hunting eagles have reportedly been laid-off by the Swiss government due to concerns about the welfare of the birds, which awkwardly follows the recent tech industry layoffs, including Meta’s announcement on November 9 to let go of more than 11,000 employees.

The anticipated 2022 tech layoffs have not just dug their claws into drone-grounding eagles that were employed to hunt down the technology, but the tech industry itself, according to an article by Gizmodo on Tuesday.

Why does the world’s richest person need more cash?

Days after agreeing to acquire Twitter for his initial offer of $44 billion, Elon Musk sold off Tesla stock worth nearly $4 billion in the days between November 4 and November 8, the Wall Street Journal.

Last year, Musk became the world’s richest person riding on the stock value of his electric car-making company, Tesla. At its peak price of $410 a piece, Musk’s personal worth reached a never-before figure of $340 billion last year. As we turned into the new year, Tesla stock started shedding the rapid gains, and as 2022 draws to a close, it is now down 45 percent, a Bloomberg report said.
