New brain implant could move paralyzed limbs with just a thought

It’s called a stent-electrode recording array, and it has been used for the last few years for neurological conditions, according to a paper by University of Melbourne researchers. But a 39-person team from 16 of the university’s departments think it could be used to make people walk again. But wait it gets even better.

Implantable brain device to “enable direct recording from neurons” and let paralysed move again

A DARPA-funded research team has created a novel neural-recording device that can be implanted into the brain through blood vessels, reducing the need for invasive surgery and the risks associated with breaching the blood-brain barrier. The technology was developed under DARPA’s Reliable Neural-Interface Technology (RE-NET) program, and offers new potential for safely expanding the use of brain-machine interfaces (BMIs) to treat physical disabilities and neurological disorders.

In an article published in Nature Biotechnology, researchers in the Vascular Bionics Laboratory at the University of Melbourne led by neurologist Thomas Oxley, M.D., describe proof-of-concept results from a study conducted in sheep that demonstrate high-fidelity measurements taken from the motor cortex—the region of the brain responsible for controlling voluntary movement—using a novel device the size of a small paperclip.

High-fidelity intracranial electrode arrays for recording and stimulating brain activity have facilitated major advances in the treatment of neurological conditions over the past decade. Traditional arrays require direct implantation into the brain via open craniotomy, which can lead to inflammatory tissue responses, necessitating development of minimally invasive approaches that avoid brain trauma. Here we demonstrate the feasibility of chronically recording brain activity from within a vein using a passive stent-electrode recording array (stentrode). We achieved implantation into a superficial cortical vein overlying the motor cortex via catheter angiography and demonstrate neural recordings in freely moving sheep for up to 190 d. Spectral content and bandwidth of vascular electrocorticography were comparable to those of recordings from epidural surface arrays. Venous internal lumen patency was maintained for the duration of implantation. Stentrodes may have wide ranging applications as a neural interface for treatment of a range of neurological conditions.

I was recently invited to speak at a school with two Estonian Student Satellite Program (ESTCube) members. Here’s me talking (the microphone made us look like a band 😂) about the electric solar wind sail which could propel superfast spacecraft and get us to deep-space in the shortest time yet. It was invented by Pekka Janhunen and a Finnish nanosatellite is set to test its working principles this year. Hopefully ESTCube will test it soon enough as well. 

Slack, diversity win big at ‘Crunchies’ tech awards

Slack won for Fastest Rising Startup. The audience — and Twitterverse — were thrilled when a team of engineers, all women of color, accepted it.

“There are many things that are major keys to the success of Slack, not least of which are diversity and inclusion,” Kiné Camara said as she accepted the award. “The idea that diversity helps companies improve the culture and the bottom line may be somewhat controversial. But all we know is we’ve got 9% of women of color in engineering at Slack … and we are the fastest growing enterprise software of all time.” [+]
