Oleg glances furtively around him and, confident that nobody is watching, slips inside the entrance to a decaying Soviet-era block of flats, where Sasha is waiting for him. Ensconced in the dingy kitchen of one of the apartments, they empty the contents of a blue carrier bag that Oleg has brought with him — painkillers, iodine, lighter fluid, industrial cleaning oil, and an array of vials, syringes, and cooking implements. Half an hour later, after much boiling, distilling, mixing and shaking, what remains is a caramel-coloured gunge held in the end of a syringe, and the acrid smell of burnt iodine in the air. Sasha fixes a dirty needle to the syringe and looks for a vein in his bruised forearm. After some time, he finds a suitable place, and hands the syringe to Oleg, telling him to inject the fluid.

But not every aspect of this series has delighted viewers. There's been some frustration with folks about the show's episode lengths. They're pretty short! The series premiere episode last year dropped at a svelte 39 minutes — While cable and satellite providers continued to see customers flee during Q3, live TV streaming services are reaching new heights thanks to the return of live sports. The DC Comics series will conclude after its upcoming fourth season. The CW said earlier it was developing a spinoff around the villain Painkiller, who has been played by Jordan Calloway. A backdoor pilot for the series will air as the seventh episode of the now-final fourth season. Television Group.

Sophisticated imaging technologies like functional magnetic resonance can give you some clues. For decades, technologists have been trying to get brains to interface with computer keyboards or robot arms, to get meat to commune with silicon.

On Wednesday, a team of scientists and engineers showed results from a promising new approach. It involves mounting electrodes on an expandable, springy tube called a stent and threading it through a blood vessel that leads to the brain. Patients go home in a couple of days. It took training once the subjects got home. The electrode-studded stent could pick up signals from the brain, but machine-learning algorithms have Chasing Heroin Is A Documentary Giving Us figure article source what those signals—imperfect reflections of a mind at work even under ideal conditions—actually represent.

But after a few weeks of work, both patients could use an eye tracker to move a cursor and then click with a thought, using the implant. For now, all the stentrode is picking up is one bit of information—either a telepathic mouse-click or the absence of that click. Much more ambitious brain-computer interfaces and neural prosthetics have been in the news lately. The company has so far only shown short-term use in pigs. Plus, the brain sloshes around like jelly in a donut; fixed-in-place electrodes can damage it. But get it right and they can do more than brain research. Meanwhile, electrodes placed directly onto the scalp can pick up brain waves—electroencephalograms, or EEGs—but those lack the spatial detail of implanted electrodes.

A more recent innovation, electrocorticography, places a mesh of electrodes directly onto the surface of the brain. In combination with smart spectral processing of the signals those electrodes pick up, ECoG is good enough to translate action in the part of the motor cortex that controls the lips, jaw, and tongue into text or even speech. And there are other approaches. Kernel uses functional near-infrared spectroscopy on the head to sense brain activity.

Closer to the first thing than the second, its inventors hope. A possible problem: Tissue conducts electrical impulses, but the electrodes in the stent are picking up signals from the brain through the cells of the blood vessel. That lowers signal content. Chasing Heroin Is A Documentary Giving Us for transparency, I should point out that Gilja has done for-pay work with BCI companies including Neuralink, with whom Synchron could theoretically compete someday. They might find better locations for the stent, in blood vessels adjacent to other brain areas of interest; anywhere within 2 millimeters of a vessel big enough to accommodate the stentrode is fair game, Oxley says. The software could stand some improving, in terms of figuring out what the brain actually means when it emits its electrical bells and whistles, and some of their tests suggest the system could pick up more informational detail—like which specific muscle the users were trying to contract. That could lead to more useful prosthetics or control of devices beyond Windows Adam Rogers writes about science and miscellaneous geekery.
