Interestingly enough, although Elon Musk’s Neuralink received a great deal of media attention, early in 2023, Synchron published results from its first-in-human study of four patients with severe paralysis who received its first-generation Stentrode neuroprosthesis implant. The implant allowed participants to create digital switches that controlled daily tasks like sending texts and emails, partaking in online banking, and communicating care needs. The study’s findings were published in a paper in JAMA Neurology in January 2023. Then, before September, the first six US patients had the Synchron BCI implanted. The study’s findings are expected by late 2024.

Let’s return to Upgrade. “One part The Six Million Dollar Man, one part Death Wish revenge fantasy” was how critics described the movie. While Death Wish is a 1974 American vigilante action-thriller movie that is partially based on Brian Garfield’s 1972 novel of the same name, the American sci-fi television series The Six Million Dollar Man from the 1970s, based on Martin Caidin’s 1972 novel Cyborg, could be considered a landmark in the context of human-AI symbiosis, although in fantasy’s domain. Oscar Goldman’s opening line in The Six Million Dollar Man was, “Gentlemen, we can rebuild him. We have the technology. We have the capability to make the world’s first bionic man… Better than he was before. Better—stronger—faster.” The term “cyborg” is a portmanteau of the words “cybernetic” and “organism,” which was coined in 1960 by two scientists, Manfred Clynes and Nathan S Kline.

At the moment, “cyborg” doesn’t seem to be a narrative of a distant future, though. Rather, it’s very much a story of today. We are just inches away from becoming cyborgs, perhaps, thanks to the brain chip implants, although Elon Musk perceives that “we are already a cyborg to some degree,” and he may be right. Cyborgs, however, pose a threat, while the dystopian idea of being ruled by Big Brother also haunts. Around the world, chip implants have already sparked heated discussions on a variety of topics, including privacy, the law, technology, medicine, security, politics, and religion. USA Today published a piece headlined “You will get chipped—eventually” as early as August 2017. And an article published in The Atlantic in September 2018 discussed how (not only brain chips but) microchip implants, in general, are evolving from a tech-geek curiosity to a legitimate health utility and that there may not be as many reasons to say “no.” But numerous concerns about privacy and cybersecurity would keep us haunted. It would be extremely difficult for policymakers to formulate laws pertaining to such sensitive yet quickly developing technology.

Scientists can now 3D print more-realistic prosthetic eyes in a fraction of the time and effort required by traditional approaches.

Summary: Researchers made a groundbreaking discovery on how the human brain forms words before speaking. By utilizing Neuropixels probes, they’ve mapped out how neurons represent speech sounds and assemble them into language.

This study not only sheds light on the complex cognitive steps involved in speech production but also opens up possibilities for treating speech and language disorders. The technology could lead to artificial prosthetics for synthetic speech, benefiting those with neurological disorders.

Dr. David Cohen comments on 10-year results from a trial of transcatheter vs. surgical aortic valve replacement:

Over the past decade, transcatheter aortic valve replacement (TAVR) has evolved from a niche procedure to treat severe aortic stenosis in high-risk patients to a mainstream procedure that is also performed in intermediate-and low-risk patients. With this evolution in practice, the large number of younger patients with life expectancies 10 years now receiving TAVR has raised concerns about its durability and patients’ long-term outcomes. Now, 10-year results are available from the NOTION trial of TAVR versus surgical aortic valve replacement (SAVR) that was conducted between 2009 and 2013 (NEJM JW Cardiol May 29 2015 and J Am Coll Cardiol 2015; 65:2184).

Two hundred eighty patients aged 70 years (mean age, 79 years; mean predicted risk of surgical mortality, 3%) were randomized to SAVR using any commercially available bioprosthesis or TAVR using the first-generation self-expanding CoreValve device. At 10-year follow-up, there was no significant between-group difference in the composite of death, stroke, or myocardial infarction (66% for both groups) or any of the individual components. Rates of bioprosthetic valve failure and repeat valve intervention were also similar. However, the rate of bioprosthetic valve dysfunction was lower with TAVR, largely reflecting lower rates of patient–prosthesis mismatch. The rate of structural valve deterioration was lower with TAVR as well, driven mainly by lower transvalvular gradients with TAVR that emerged early and persisted throughout follow-up.

Researchers have built a device that helps users feel temperature through a prosthetic arm. A new study shows it works with high accuracy.

A few years ago, a team of researchers working under Professor Stanisa Raspopovic at the ETH Zurich Neuroengineering Lab gained worldwide attention when they announced that their prosthetic legs had enabled amputees to feel sensations from this artificial body part for the first time.

Unlike commercial leg prostheses, which simply provide amputees with stability and support, the ETH researchers’ prosthetic device was connected to the sciatic nerve in the test subjects’ thigh via implanted electrodes.

This electrical connection enabled the neuroprosthesis to communicate with the patient’s brain, for example relaying information on the constant changes in pressure detected on the sole of the prosthetic foot when walking. This gave the test subjects greater confidence in their prosthesis—and it enabled them to walk considerably faster on challenging terrains.

There’s a real life bionic woman, and a mindblowing technological advancement has made her life a lot better.

To show one of the advantages of being a cyborg, I typed my old prescription into ZEISS Optical Inserts which are for use with the Apple Vision Pro and it said “We are really sorry, but your prescription values go beyond the available range.” But now that I’m a cyborg with artificial lenses, any…

We need your eyeglass prescription to create your ZEISS Optical Inserts – Prescription (sometimes also called distance prescription). This is why we ask you to upload it.

Contact lens prescriptions or ones for task-specific uses (office or computer glasses, near reading glasses) don’t qualify.

SNAP’s 144 gold-coated silicon microneedles, each shorter than a hundredth of an inch, can bypass pain receptors and ensure comfort during prolonged wear.

Engineers from Korea and the United States have developed a wearable patch, which is slated to have the potential to further technologies related to human-machine interaction and healthcare.

Like a Band-Aid, the stretchable microneedle adhesive patch (SNAP) sticks to your skin and detects signals from muscles. In tests, people used it to control robotic exoskeletons better. These machines copy and improve the strength of human muscles and bones.
