3D Nanoprinted Electrodes Hold Potential for Personalized Treatment of Neurological Disorders

3D Nanoprinted Electrodes Holds Potential for Personalized Treatment of Neurological Disorders

By Margaret Davis

Researchers from Carnegie Mellon University pioneered the CMU Array, a new type of microelectrode array (MEA) for brain-computer interface platforms that holds the potential for how doctors treat neurological disorders.

Phys.org reported that the MEA is 3D-printed at a fully customizable nanoscale, which means that patients suffering from epilepsy or limb function loss could someday have a personalized treatment plan. The researchers applied the newest microfabrication technique and Aerosol Jet 3D printing to produce the MEA and solve design barriers of other brain-computer interfaces (BCI) arrays.

New RNA Tool Can Illuminate Brain Circuits and Edit Specific Cells

Tagging and illuminating only the inhibitory “brake” cells (green) in human brain tissue is just one of many things the new tool from Duke University, CellREADR, can do.

Editing technology is precise and broadly applicable to all tissues and species.

Scientists at Duke University have developed an RNA-based editing tool that targets individual cells, rather than genes. It is capable of precisely targeting any type of cell and selectively adding any protein of interest.

Researchers said the tool could enable modifying very specific cells and cell functions to manage disease.

Using an RNA-based probe, a team led by neurobiologist Z. Josh Huang, Ph.D. and postdoctoral researcher Yongjun Qian, Ph.D. demonstrated they can introduce into cells fluorescent tags to label specific types of brain tissue; a light-sensitive on/off switch to silence or activate neurons of their choosing; and even a self-destruct enzyme to precisely expunge some cells but not others. The work will be published today (October 5, 2022) in the journal Nature.

Their selective cell monitoring and control system relies on the ADAR enzyme, which is found in every animal’s cells. While these are early days for CellREADR (Cell access through RNA sensing by Endogenous ADAR), the possible applications appear to be endless, Huang said, as is its potential to work across the animal kingdom.

Google AI Allows You to ‘Fly’ Into a Landscape Photograph

 By MATT GROWCOOT

Google has created a program where the viewer can “fly into” a still photo using artificially intelligent (AI) 3D models. 

In a new paper entitled InfiniteNature-Zero, the researchers take a landscape photo and then use AI to “fly” into it like a bird, with clever software generating a fake landscape thanks to machine learning. 

When facing the daunting task, researchers had to fill in information that a still photo doesn’t provide, such as hidden areas in a photo. For example, a spot that is hidden behind trees needs to be generated. This can be done by “inpainting,” the AI will simulate what it thinks would be there by the process of machine learning with huge datasets. 

Similarly, to get the flying effect, the AI has to generate what is outside of the photograph’s borders. This is called “outpainting” and is much like the content-aware tool in Photoshop where the AI will generate a wider image based upon the original photo and aided by its deep learning from massive datasets. 

As anyone who has ever zoomed into a photo will know, the image quality falls apart as its breaks down into blurry pixels. To stop this from happening, Google uses superresolution, a process where AI synthesizes a noisy, pixellated image into a crisp one.

Space Force’s digital push focuses on ‘Spaceverse’

Goal is to create virtual, immersive environments that train Guardians and rapidly develop systems

By Courtney Albon

WASHINGTON — Last fall, the U.S. Space Force gave defense companies an unprecedented look at its initial plan to make missile warning satellites more resilient against potential threats from China.

The business fair was unique in a few ways. It offered industry a deeper understanding of the challenges the service expects to face over the next few decades as adversaries advance space and missile technology and test on-orbit weapons. It also paired that analysis with a roadmap of the capabilities the Space Force thinks it needs to protect against these growing threats — work the service doesn’t typically reveal until much later in the acquisition process.

Perhaps the most significant feature of that October 2021 meeting was that the models it shared with industry to show its analysis of the space environment and the counter-space threats were all digital.

Speaking at the Air and Space Force Conference in National Harbor, Md., last month, Chief of Space Operations Gen. Jay Raymond said the meeting and those models were a first step toward creating what the service calls a “digital thread,” which is essentially a virtual record of a product that continues throughout its lifecycle.

The idea, he said, is for programs to have that thread from the beginning, making it easier to define capability gaps, build a system, test it, inject into a simulated training environment and operate it over time.

“If we do this right, we can take everything from force design to requirements . . . to acquiring the capabilities and testing the capabilities and training our Guardians on those systems — all using the same digital thread,” Raymond said Sept. 20. “That’s nirvana. We’re not close to that. But we’ve taken a good step. We’ve done the digital design, we’re figuring out what that digital requirements process is, and I think it’s going to pay significant dividends for us as we move forward.”

While the thread is central to the Space Force’s vision to be the world’s first fully digital military branch, it’s only one piece. Last May, the service released a vision document that laid out its priorities in this area, which include developing a “digitally fluent” workforce, connecting its field commands in a virtual environment and ensuring that decision-making is informed by data.

Lisa Costa, the Space Force’s Chief Technology and Innovation Officer, told C4ISRNET in an interview that as the service’s leader on implementing this digital vision, her team is focused on three critical areas: creating virtual, immersive environments to train Guardians and develop systems; working with industry to procure digital infrastructure; and identifying future problem sets and capabilities to inform technology and research investments.

Tesla Showed “Cybertruck On Mars” AI-Generated Images During AI Day

Tesla used artificial intelligence on its supercomputer to create images of made-up Cybertrucks. 

By: Andrei Nedelea

Tesla says it used its artificial intelligence running on its Dojo supercomputer to create the six images featuring Tesla trucks pictured on the surface of the planet Mars. The images were shown during the recent AI Day presentation; the images it produced are interesting and they show the power of such tools, as well as their limitations.

What makes the Dojo supercomputer special is that it doesn’t use third-party components, with all its internals being designed in-house by Tesla. And whereas previously Tesla used Nvidia graphics processors, now even those have been replaced with Tesla’s own chips. The manufacturer developed Dojo especially to reduce the latency that its neural network developers encounter when making updates.

The images shown during AI Day were also processed by a Dojo supercomputer, using an internal software tool that looks similar to others which are publicly available. But you don’t need your own Dojo to get similar, or even better results, as we found out using a text-to-image AI generation platform called Midjourney.

Working like bees, 3D-printing drones could change the future of construction

The drones could be used to build shelters in harsh conditions both on Earth and in space.

By Teodosia Dobriyanova  

A team of researchers at Imperial College London and Empa have been developing collaborative aerial drones. Inspired by the work of bees, the scientists are training the robots to construct 3D printed buildings from a single blueprint.

To ensure maximum accuracy, the cooperative drones would complete their own tasks and then supervise the work of their peers. The drones are fully autonomous once in flight and have so far successfully completed tests with lightweight cement mixtures.

This New Hydrogen-Powered Sailing Catamaran Cruises Emissions Free While Generating Its Own Fuel

The 80-footer will also feature Sunreef’s patented “solar skin”— which will see the world’s lightest solar cells fully integrated into the bodywork. 

BRACHEL CORMACK

Sunreef Yachts has been at the forefront of eco-innovation in the marine world for the past two decades. It’s not exactly surprising, then, that the Polish yard announced another groundbreaking project at this year’s Monaco Yacht Show.

Sunreef’s founder and president Francis Lapp took the stage to share that the team was recently commissioned to build an 80-foot sailing catamaran that will combine hydrogen power and electric propulsion to achieve “unrivaled autonomy for a new level of eco-conscious cruising.”

According to Lapp, hydrogen will be used to power both the cat’s appliances and electric motors. The 80-footer will also feature Sunreef’s patented photovoltaic system—sometimes referred to as a “solar skin”— which will see the world’s lightest solar cells fully integrated into the composite bodywork. This allows the cat to generate clean, green energy from the sun and then store it in the built-in batteries. Sunreef’s R&D department is currently developing a system that will use this solar power to produce hydrogen onboard. That means you could eventually sail the high seas silently and sans emissions while generating your own fuel. Not bad.

Dronamics deal to allow net-zero middle-mile drone delivery flights

By Bruce Crumley

Europe’s middle-mile drone delivery specialist Dronamics is moving to make its flagship Black Swan UAVs entirely carbon neutral through a linkup with UK company Zero Petroleum to supply fossil-free fuel for future aerial cargo transport.

The partnership is the most recent in a series of deals Dromamics has revealed as it prepares to launch middle-mile drone transport of goods and medical materials across Europe as an option to existing road alternatives to destinations shorter-distance delivery UAVs don’t reach. Under the accord, Zero Petroleum will provide its ZERO SynAVGAS fossil-free fuel to power Black Swan craft on entirely sustainable, carbon-neutral flights of up to 2,500 km.

The companies describe ZERO SynAVGAS as a direct-drop replacement for traditional fossil-based fuels without any engine performance loss other synthetics can involve. It’s manufactured by extracting hydrogen from water and capturing carbon from atmospheric carbon dioxide, a process that emits the exact volume of carbon it burns. It becomes 100% sustainable when powered by renewable energy tech like solar or wind, and will be used in specially designed Rotax propeller engines that Dromamics will equip its delivery drones with.

DARPA developed a brain-zapping prosthesis that improves memory by 50%

By Joshua Hawkins

Memory loss is a terrible thing. With so many brain injuries and diseases able to cause significant loss of memory, scientists have spent a long time looking for ways to restore or improve memory in those cases. Now, a group of researchers has managed to create a memory-improving prosthesis with an improvement rate of around 50 percent.

The new and unique form of brain stimulation mimics how the brain creates memories. The system isn’t extremely advanced at the moment, relying on a single electrode that needs to be situated deep into the brain. However, the memory-improving prosthesis has shown amazing effectiveness overall and could probably be even more impressive with a more advanced setup.

If that happens, the possibilities of what they could do with it are astounding. The memory-improving prosthesis works by copying exactly what the human brain’s hippocampus does. This part of the brain is vital to memory storage and creation.

The researchers initially tested it in animals and in some patients with epilepsy. During this time, they tested two different versions of the memory-improving prosthesis in 24 different people. The researchers implanted electrodes to study the patient’s epilepsy. Some of these individuals also had brain injuries and saw results change depending on the electrode used.
