The Next Frontier for Brain Implants Is Artificial Vision

Posted by in categories: biotech/medical, computing, cyborgs, Elon Musk

In 2021, he heard about a trial of a visual prosthesis at Illinois Institute of Technology in Chicago. Researchers cautioned that the device was experimental and he shouldn’t expect to regain the level of vision he had before. Still, he was intrigued enough to sign up. Thanks to the chips in his brain, Bussard now has very limited artificial vision—what he describes as “blips on a radar screen.” With the implant, he can perceive people and objects represented in white and iridescent dots.

Bussard is one of a small number of blind individuals around the world who have risked brain surgery to get a visual prosthesis. In Spain, researchers at Miguel Hernández University have implanted four people with a similar system. The trials are the culmination of decades of research.

There’s interest from industry, too. California-based Cortigent is developing the Orion, which has been implanted in six volunteers. Elon Musk’s Neuralink is also working on a brain implant for vision. In an X post in March, Musk said Neuralink’s device, called Blindsight, is “already working in monkeys.” He added: “Resolution will be low at first, like early Nintendo graphics, but ultimately may exceed normal human vision.”

Pea-Sized Human Brain Stimulator Invented

Posted by in categories: biotech/medical, robotics/AI

Summary: Researchers developed a groundbreaking pea-sized brain stimulator, the Digitally Programmable Over-brain Therapeutic (DOT), capable of wireless operation through magnetoelectric power transfer. This implantable device promises to revolutionize treatment for neurological and psychiatric disorders by enabling less invasive and more autonomous therapeutic options compared to traditional neurostimulation methods.

The DOT’s ability to stimulate the brain through the dura without implanted batteries represents a significant advancement in medical technology, offering potential treatments for conditions like drug-resistant depression directly from the comfort of one’s home. This innovation could change the landscape of how brain-related disorders are managed, emphasizing patient comfort and control.

Fusion to Warp Drive with a Hint of Antigravity

Posted by in categories: education, habitats, health, space travel

Jason Cassibry, Ph.D., explains his team’s research and experiments in the areas of fusion, warp drive and even a mention of antigravity propulsion. A mention is also made as to what happened to Ning Li (more on that in a subsequent video). This was a presentation to the Huntsville Alabama L5 Society, a chapter of the National Space Society. There is a lot of technical discussion with the audience who were almost all engineers and scientist.

Quantum Systems: Potential Improvements and Future Developments

Posted by in categories: computing, particle physics, quantum physics

“Interfacing two key devices together is a crucial step forward in allowing quantum networking, and we are really excited to be the first team to have been able to demonstrate this,” said Dr. Sarah Thomas.

How close are we to making quantum computing a reality? This is what a recent study published in Science Advances hopes to address as an international team of researchers discuss recent progress in how quantum information is both stored and then transmitted over long distances using a quantum memory device, which scientists have attempted to develop for some time. This study holds the potential to help scientists better understand the processes responsible for not only making quantum computing a reality, but also enabling it to work as seamlessly as possible.

While traditional telecommunications technology uses “repeaters” to prevent the loss of information over long distances, quantum computing cannot use such technology since it will destroy quantum information along the way. While quantum computing uses photons (particles of light) to send information, storing the information using a quantum memory device for further dissemination has eluded researchers for some time. Therefore, to combat the problem of sending quantum information over long distances, two devices are required: the first will send the quantum information while the second will store them for later dissemination.

A single atom layer of gold—researchers create goldene

Posted by in categories: chemistry, particle physics

For the first time, scientists have managed to create sheets of gold only a single atom layer thick. The material has been termed goldene. According to researchers from Linköping University, Sweden, this has given the gold new properties that can make it suitable for use in applications such as carbon dioxide conversion, hydrogen production, and production of value-added chemicals. Their findings are published in the journal Nature Synthesis.

Scientists have long tried to make single-atom-thick sheets of gold but failed because the metal’s tendency to lump together. But researchers from Linköping University have now succeeded thanks to a hundred-year-old method used by Japanese smiths.

“If you make a material extremely thin, something extraordinary happens—as with graphene. The same thing happens with gold. As you know, gold is usually a metal, but if single-atom-layer thick, the gold can become a semiconductor instead,” says Shun Kashiwaya, researcher at the Materials Design Division at Linköping University.

Los Alamos Pushes The Memory Wall With “Venado” Supercomputer

Posted by in categories: military, supercomputing

Today is the ribbon-cutting ceremony for the “Venado” supercomputer, which was hinted at back in April 2021 when Nvidia announced its plans for its first datacenter-class Arm server CPU and which was talked about in some detail – but not really enough to suit our taste for speeds and feeds – back in May 2022 by the folks at Los Alamos National Laboratory where Venado is situated.

Now we can finally get more details on the Venado system and get a little more insight into how Los Alamos will put it to work, and more specifically, why a better balance of memory bandwidth and compute that depends upon it is perhaps more important to this lab than it is in other HPC centers of the world.

Los Alamos was founded back in 1943 as the home of the Manhattan Project that created the world’s first nuclear weapons. We did not have supercomputers back then, of course, but plenty of very complex calculations have always been done at Los Alamos; sometimes by hand, sometimes by tabulators from IBM that used punch cards to store and manipulate data – an early form of simulation. The first digital computer to do such calculations at Los Alamos was called MANIAC and was installed in 1952; it could perform 10,000 operations per second and ran Monte Carlo simulations, which use randomness to simulate what are actually deterministic processes.

Australian writers have been envisioning AI for a century. Here are 5 stories to read as we grapple with rapid change

Posted by in category: robotics/AI

I found this on NewsBreak:

Australians are nervous about AI. Efforts are underway to put their minds at ease: advisory committees, consultations and regulations. But these actions have tended to be reactive instead of proactive. We need to imagine potential scenarios before they happen.

Of course, we already do this – in literature.
