Weird magic neurons in the spine can make people with paralysis walk again

Posted by in categories: biotech/medical, neuroscience

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.

Tech industry clawed by crisis: Layoff of Swiss drone-hunting eagles followed by Meta’s 11,000 employees

Posted by in categories: drones, government

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.

Elon Musk sold $4 billion worth of Tesla stock following the Twitter

Posted by in categories: Elon Musk, sustainability, transportation

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.

Atomic changes in metals could lead to longer-lasting batteries

Posted by in categories: materials, transportation

Researchers at Pacific Northwest National Laboratory (PNNL) are studying the atomic-level changes in metals undergoing shear deformation in order to deduce the effects of physical forces on these materials, according to a report by Phys.org published on Monday.

The work could lead to many new and improved applications such as longer-lasting batteries and lighter vehicles.

A new leaf unfolds in artificial photosynthesis

Posted by in categories: chemistry, solar power, sustainability

In 2021, researchers from Toyota Central R&D Labs developed a large, cost-effective artificial photosynthesis system that produces industrial formate at a solar-to-chemical conversion efficiency (ηSTC) of 10.5%1. Researchers from the lab say that, to their knowlege, this ηSTC is a first for a one metre squared cell.

Within the next 10 years, the company aims to establish artificial photosynthesis technology for wide-scale production of useful carbon compounds.

Astronauts Command Robotic Arm to Capture Cygnus

Posted by in categories: robotics/AI, space

At 5:20 a.m. EST, NASA astronaut Nicole Mann, with NASA astronaut Josh Cassada acting as backup, captured Northrop Grumman’s Cygnus spacecraft using the International Space Station’s Canadarm2 robotic arm. Mission control in Houston will actively command the arm to rotate Cygnus to its installation orientation and then to guide it in for installation on the station’s Unity module Earth-facing port.

NASA Television, the NASA app, and agency’s website will provide live coverage of the spacecraft’s installation beginning at 7:15 a.m.

The Cygnus spacecraft launched Monday on an Antares rocket from NASA’s Wallops Flight Facility, Virginia at 5:32 a.m. This is Northrop Grumman’s 18th commercial resupply mission to the International Space Station for NASA. The Cygnus spacecraft is carrying a supply of 8,200 pounds of scientific investigations and cargo to the orbiting laboratory.

We might have Alzheimer’s all wrong

Posted by in categories: biotech/medical, neuroscience

For over 30 years, toxic proteins were thought to cause Alzheimer’s. However, recent studies suggest it might be metabolic reprogramming.
