Some Children With Covid-Related Syndrome Develop Neurological Symptoms

New research found that half of young patients with the inflammatory condition, MIS-C, in a London hospital experienced confusion, hallucinations and other issues, in addition to physical symptoms.

How does the brain interpret computer languages?

Image of a pillar covered in lit ones and zeroes.

In the US, a 2016 Gallup poll found that the majority of schools want to start teaching code, with 66 percent of K-12 school principals thinking that computer science learning should be incorporated into other subjects. Most countries in Europe have added coding classes and computer science to their school curricula, with France and Spain introducing theirs in 2015. This new generation of coders is expected to boost the worldwide developer population from 23.9 million in 2019 to 28.7 million in 2024.

Despite all this effort, there’s still some confusion on how to teach coding. Is it more like a language, or more like math? Some new research may have settled this question by watching the brain’s activity while subjects read Python code.

Two schools on schooling

Right now, there are two schools of thought. The prevailing one is that coding is a type of language, with its own grammar rules and syntax that must be followed. After all, they’re called coding languages for a reason, right? This idea even has its own snazzy acronym: Coding as Another Language, or CAL.

Kernel raises $53 million for its non-invasive ‘Neuroscience as a Service’ technology

LA-based bio science startup Kernel has raised $53 million from investors including General Catalyst, Khosla Ventures, Eldridge, Manta Ray Ventures, Tiny Blue Dot and more. The funding is the first outside money that Kernel has taken in, though it’s a Series C round, because founder and CEO Bryan Johnson has provided $54 million in investment for Kernel to date. Johnson also participated in this latest round alongside external investors.

The funding will go towards further scaling “on-demand” access to its non-invasive technology for recording brain activity, which consists of two main approaches. Kernel has distinguished these as two separate products: Flow, which detects magnetic fields created by the collective activity of neutrons in the brain; and Flux, which measures blood through through the brain. These are both key signals that researchers and medical practitioners monitor when working with the brain, but typically they require use of invasive, expensive hardware – or even brain surgery.

Kernel’s goal is to make this much more broadly available, offering access via a ‘Neuroscience as a Service’ (NaaS) model that can provide paying clients access to its brain imaging devices even remotely. Earlier this year, Kernel announced that this platform was available generally to commercial customers.

The technology sounds like sci-fi – but it’s really an attempt to take what has been a relatively closed and prohibitively costly, expert and potentially dangerous to its subjects tech, and make it available as an on-demand capability – in much the same way that many human genome companies have emerged to take advantage of the advances in the speed and availability of human genome sequencing to do the same, for the business and research community.

Johnson’s ambitious long-term goal with the company is to ultimately develop a much deeper understanding in the field of neuroscience.

“If we can quantify thoughts and emotions, conscious and subconscious, a new era of understanding, wellness, and human improvement will emerge,” Johnson writes in a press release.

It’s true that the brain’s inner workings are still largely a mystery to most researchers, especially in terms of how they translate to our cognition, feelings and actions. Kernel’s platform could mean significantly more people studying the

MIT’s tiny artificial brain chip could bring supercomputer smarts to mobile devices

Researchers at MIT have published a new paper that describes a new type of artificial brain synapse which offers performance improvements vs. other exiting versions, and which can be combined in volumes of tens of thousands on a chip that’s smaller physically than a single piece of confetti. The results could help create devices that can handle complex AI computing locally, while remaining small and power-efficient, and without having to connect to a data center.

The researchers team created what are known as “memristors” – essentially simulated brain synapses created using silicon, but also used alloys of silver and copper in their construction. The result was a chip that could effectively ‘remember’ and recall images in very high detail, repeatedly, with much crisper and more detailed ‘remembered’ images than in other types of simulated brain circuits that have come before.

What the team wants to ultimately do is recreate large, complex artificial neural networks which are currently based in software that requires significant GPU computing power to run – but as dedicated hardware, so that it can be localized in small devices including potentially your phone, or a camera.

Unlike traditional transistors, which can switch between only two states (0 or 1) and which form the basis of modern computers, memsistors offer a gradient of values, much more like your brain, the original analog computer. They can also ‘remember’ these states so that they can easily recreate the same signal for the same received current multiple times over.

What the researchers did here was borrow a concept from metallurgy: When metallurgists want to change the properties of a metal, they combine it with another that has that desired property to create an alloy. Similarly, the researchers here found an element they could combine with the silver they use as the memristor’s positive electrode, in order to make it better able to consistently and reliably transfer ions along even a very thin conduction channel.

That’s what enabled the team to create super small chips that contain tens of thousands of memristors that can nonetheless not only reliably recreate images from ‘memory,’ but also perform inference tasks like improving the detail of, or blurring the original image on command, better than other, previous memristors created by other scientists.

It’s still a long way off, but the team behind this project suggest that eventually, this could lead to portable, artificial brain computers that can perform very complex tasks on the scale of today’s supercomputers – with minimal power requirements and without any network connection required.
