For the longest time, Google’s new Fuchsia operating system remained a bit of a mystery — with little information in terms of the company’s plans for it, even as the team behind it brought the code to GitHub under a standard open-source license. These days, we know that it’s Google’s first attempt at developing a completely new kernel and general purpose operating system that promises to be more than just an experiment (or a retention project to keep senior engineers from jumping ship). For the most part, though, Google has remained pretty mum about the subject.

It seems like Google is ready to start talking about Fuchsia a bit more now. The company today announced that it is expanding the Fuchsia open-source community and opening it up to contributions from the public. Typically, companies start opening up their open-source projects to outside contributors once they feel they have achieved a stable foundation that others can build on.

“Starting today, we are expanding Fuchsia ‘s open source model to make it easier for the public to engage with the project,” the team writes. “We have created new public mailing lists for project discussions, added a governance model to clarify how strategic decisions are made, and opened up the issue tracker for public contributors to see what’s being worked on. As an open source effort, we welcome high-quality, well-tested contributions from all. There is now a process to become a member to submit patches, or a committer with full write access.”

WASHINGTON: Scientists are a step closer to restoring vision for the blind, after building an implant that bypasses the eyes and allows monkeys to perceive artificially induced patterns in their brains.

The technology, developed by a team at the Netherlands Institute for Neuroscience (NIN), was described in the journal Science on Thursday.

It builds on an idea first conceived decades ago: electrically stimulating the brain so it “sees” lit dots known as phosphenes, akin to pixels on a computer screen.

It’s been four years, and we still don’t really know what Google intends to do with this OS.

It’s been over four years since we first found out that Google is developing a new operating system called Fuchsia. It’s unique because it’s not based on a Linux kernel; instead, it uses a microkernel called Zircon. It’s also unique because, despite being developed “in the open” on publicly browsable repositories, nobody really understands what the OS is for, and Google executives have been remarkably coy about it all.

Today, that mix of trends continues as the company announces that it’s opening up a little more by asking for more public contributors from outside its organization. Google says it has “created new public mailing lists for project discussions, added a governance model to clarify how strategic decisions are made, and opened up the issue tracker for public contributors to see what’s being worked on.”

It’s been a while since we’ve seen a dive into the code and documentation Google has made available, though there are some early UI examples. Google’s post today emphasizes that “Fuchsia is not ready for general product development or as a development target,” but it’s likely that the announcement will spur another round of analysis.

What a tough time for Cyberpunk 2077 to be launching. The newest graphics cards are unavailable unless you’re willing to overpay a scalper, and older GPUs are also hard to buy at a reasonable price because of the shortage of new ones.

The good news is that the official Cyberpunk 2077 minimum specifications are surprisingly modest, especially if you’re OK with playing at 1080p. If you want to slide everything to high at that resolution, then you’re looking at a Core i7 4790 or AMD Ryzen 3 3200G, with a GeForce GTX 1060/1660 Super or Radeon RX 470, and 12GB of RAM. That’s really not too demanding, especially from the processor perspective.

Columbia team discovers 6-nanometer-long single-molecule circuit with enormous on/off ratio due to quantum interference; finding could enable faster, smaller, and more energy-efficient devices.

Researchers, led by Columbia Engineering Professor Latha Venkataraman, report today that they have discovered a new chemical design principle for exploiting destructive quantum interference. They used their approach to create a six-nanometer single-molecule switch where the on-state current is more than 10,000 times greater than the off-state current–the largest change in current achieved for a single-molecule circuit to date.

This new switch relies on a type of quantum interference that has not, up to now, been explored. The researchers used long molecules with a special central unit to enhance destructive quantum interference between different electronic energy levels. They demonstrated that their approach can be used to produce very stable and reproducible single-molecule switches at room temperature that can carry currents exceeding 0.1 microamps in the on-state. The length of the switch is similar to the size of the smallest computer chips currently on the market and its properties approach those of commercial switches. The study is published today in Nature Nanotechnology.

I’m fairly certain that ‘massive RTX 3090 heist’ was not on your 2020 Bingo card. Our friends at Tom’s Hardware originally reported that 40 cargo boxes containing RTX 3090s were stolen this morning from an MSI factory in China in what sounds like a GTA Online-esque heist.

The stolen goods (which are valued at around $336,500) consist of roughly over 200 hard-to-find RTX 3090 graphics cards. For context, the MSRP for the RTX 3090 is around $1,500 but due to the low stock and high demand, we’ve seen them being sold for well over $2,000 on various auction sites.

Ineurals — advanced neuro-technologies for rapid learning and skill acquisition.

The 711th Human Performance Wing, under the U.S. Air Force Research Laboratory leads the development, integration, and delivery of Airman-centric research, education, and consultation enabling the U.S. Air Force to achieve responsive and effective global vigilance, global reach, and global power now and in the future. It’s comprised of the United States Air Force School of Aerospace Medicine and the Airman Systems Directorate, whose science and technology competencies include Training, Adaptive Warfighter Interfaces, Bioeffects, Bioengineering, and Aerospace and Operational Medicine.

The Individualized Neural Learning System, or iNeuraLS, is a new augmented learning platform that will enable rapid learning by closed-loop modulation of cognitive states during skill acquisition. Essentially, the AFRL team seeks to develop a capability that will give Airmen the ability to rapidly acquire knowledge and skills on the fly through direct brain interfaces with the help of neurotechnologies.

And we have not 1, but 2 fascinating guests on the show with us today:

Dr. Nathaniel Bridges serves as the Neural Interfaces Team Lead within the Air Force Research Laboratory’s Cognitive Neuroscience Section. In this role, he and his team seek to find and enable ways to link the human brain/nervous system with technology in a manner that will benefit the Air Force. This in part relies on testing and evaluating current and emerging Brain Machine/Computer Interface technologies for the Air Force and investigating the impact of various neuromodulation technologies on cognitive performance. Dr. Bridges has his PhD. in Biomedical Engineering, from Drexel University, in Philadelphia, PA USA.

Dr. Gaurav Sharma, a member of the scientific and professional cadre of senior executives, is the Senior Scientist for Cognitive Neuroscience, 711th Human Performance Wing. He serves as the principal scientific authority and independent researcher in the field of cognitive neuroscience and is in charge of initiating, planning, coordinating, evaluating and conducting research and development that increases the Air Force capabilities relative to this critical technological area. Dr. Sharma has his PhD. in Mechanical Engineering, from Northeastern University, in Boston, MA, USA.

Exploring the frontiers of neuromodulation, neurostimulation, and neural interfaces.

Neuromodulation is defined as “the alteration of nerve activity through targeted delivery of a stimulus, such as electrical stimulation or chemical agents, to specific neurological sites in the body”. It is carried out to normalize – or modulate – nervous tissue function.

Neuromodulation is an evolving therapy that can involve a range of electromagnetic stimuli such as a magnetic field, an electric current, or a drug instilled directly in the sub-dural space (i.e. intra-thecal drug delivery).

Emerging applications involve targeted introduction of genes or gene regulators and light (optogenetics), but most clinical experience has been with electrical stimulation.

Existing and emerging neuromodulation treatments also include application in medication-resistant epilepsy, chronic head pain conditions, and functional therapy ranging from bladder and bowel or respiratory control, to improvement of sensory deficits, such as hearing and vision.

Neuromodulation therapy has been investigated for other chronic conditions, such as Alzheimer’s disease, depression, chronic pain, and as an adjunctive treatment in recovery from stroke.

Dr. Amílcar dos Santos, is a practicing Psychiatrist at the Psychiatry Service of Hospital Vila Franca de Xira, in Lisbon, Portugal, with expertise in Neuromodulation / Neurostimulation, Hospitalization of acute patients, Psychiatric Emergency Service, Outpatient Psychiatry, Electroconvulsive therapy (ECT), and Psychoeducation for Bipolar Disease.

Dr. dos Santos has a Degree in Medicine from the Faculty of Medicine of the University of Lisbon (FMUL) and Post-Graduate in Neuroscience at FMUL.
