This Device Zaps the Spinal Cord to Give Paralyzed People Use of Their Hands Again

Posted by in category: biotech/medical

Reid was part of a 60-participant clinical trial that looked to use spinal cord stimulation to regain control of both hands. Similar treatments have shown promise in paraplegic patients, restoring the ability to walk in just a day. But those required surgery to place electrodes on the spinal cord.

ARC-EX therapy, by contrast, delivers two different types of electrical pulses through the skin—no surgery required. Developed by Grégoire Courtine and colleagues at the Swiss Federal Institute of Technology, the device improved hand strength, pinch, and other movements in 72 percent of participants.

Because the device is non-invasive, it’s a simple addition to physical rehabilitation programs—a sort of pilates for the fingers, explained the team. The trial only included two months of stimulation, and extending the timeline could potentially further improve results.

Scientists Discover Key Food Nutrients Linked to Slower Brain Aging

Posted by in categories: biological, food, life extension, neuroscience

Understanding the biological processes of getting older could help us lead longer lives, and stay healthier later in life – and a new study links the speed at which our brain ages with the nutrients in our diets.

Researchers from the University of Illinois and the University of Nebraska-Lincoln mapped brain scans against nutritional intake for 100 volunteers aged between 65 and 75, looking for connections between certain diets and slower brain aging.

They identified two distinct types of brain aging – and the slower paced aging was associated with nutrient intake similar to what you would get from the Mediterranean diet, shown in previous studies to be one of the best for our bodies.

Transparent metamaterial for energy-efficient regulation in building can clean itself like a lotus leaf

Posted by in categories: climatology, materials

Researchers at the Karlsruhe Institute of Technology (KIT) introduce a polymer-based material with unique properties in the journal Nature Communications. This material allows sunlight to enter, maintains a more comfortable indoor climate without additional energy, and cleans itself like a lotus leaf. The new development could replace glass components in walls and roofs in the future. The research team has successfully tested the material in outdoor tests on the KIT campus.

Deciphering how crystals form in non-classical ways

Posted by in categories: innovation, materials

Recent experimental advancements have enabled more accurate and in-depth analysis of these materials during and after formation. The review article examines two decades of research on the non-classical formation pathways of soft and organic crystalline materials. It details the current theoretical understanding of how these materials form through non-classical pathways, including distinguishing the processes of nucleation and growth across models.

Advances in experimental methods, including in-line scattering/spectroscopy detection, cryo microscopy, and in situ liquid-phase characterization, and their application to studying soft and organic crystalline materials are also discussed.

These experimental techniques have provided strong evidence for non-classical crystallization pathways, leading to key breakthroughs in understanding these processes. However, the sole presence of a specific final product or intermediate does not prove that a material formed via a specific .

Elon Musk says AI will eliminate all jobs, calls it his ‘biggest fear’

Posted by in categories: Elon Musk, employment, robotics/AI

Elon Musk, the billionaire CEO of Tesla, has said that artificial intelligence (AI) will eventually eliminate all jobs. However, he affirmed that this is not necessarily an adverse development.

Speaking at a startup and tech event in Paris on Thursday (May 23) via video link, Musk said, “Probably none of us will have a job”, while predicting a future where jobs would be “optional”

“If you want to do a job that’s kinda like a hobby, you can do a job,” Musk told VivaTech 2024. “But otherwise, AI and the robots will provide any goods and services that you want.”
