Soon miniature chips in the brain could treat degenerative diseases
The idea is to be able to stimulate several areas of the brain in a coordinated fashion. These first chips would measure just 2 to 4mm in length, and would be equipped with data recording and biphasic pulse stimulation capabilities. — AFP Relaxnews
Starfish Neuroscience is a startup cofounded in 2019 by Gabe Newell, CEO of video game publisher Valve. The company recently announced its plans to develop innovative brain-computer interfaces, in the same vein as the brain implant specialist, Neuralink.
While Neuralink's technology currently takes the form of a single implant, consisting of 1,024 electrodes, designed to interact with a specific area of the brain, Starfish Neuroscience envisages the use of several much smaller implants, each targeting a specific brain region.
The idea is to be able to stimulate several areas of the brain in a coordinated fashion. These first chips would measure just 2 to 4mm in length, and would be equipped with data recording and biphasic pulse stimulation capabilities.
On paper, these implants look tiny and would consume extremely little power, possibly even eliminating the need for recharging. A first prototype implant is due to be tested by the end of 2025.
Starfish's current focus is on medical applications, including the treatment of neurological conditions such as Parkinson's disease, depression and bipolar disorder. However, with Gabe Newell at the helm of the project, many people are already imagining video game applications, with implants specially dedicated to this purpose. This could pave the way for totally new immersive experiences. However, this vision of human-machine interaction remains the stuff of science fiction at this stage.
In the field of brain-computer interfaces, Neuralink has paved the way, with the striking example of a quadriplegic man able to play chess on a computer thanks to the implant grafted into his brain. Its next stated objective is to enable a patient to control a robotic arm, simply by the power of thought. – AFP Relaxnews

Explainer-Does escalating spat with Trump pose regulatory threat for Musk businesses?
(Reuters) -The risk U.S. transportation, environmental, communications and other regulators will take aim at Elon Musk's many businesses became a real threat after the billionaire's deep political ties with President Donald Trump disintegrated on Thursday. Below is a list of U.S. regulators who oversee Musk's companies, including automaker Tesla, rocket and satellite company SpaceX, brain implant company Neuralink, social media platform X and construction firm The Boring Company. Federal Communications Commission The Federal Communications Commission in April voted to open a review of the decades-old spectrum sharing regime between satellite systems sought by SpaceX. SpaceX wants access to new spectrum from the FCC in the coming years to speed deployment of satellite-based internet service. The review by the U.S. telecom regulator aims to allow a greater and more intensive use of spectrum for space activities. Existing reductions approved in the 1990s limit power usage that prevent better coverage from SpaceX's Starlink and other systems. Food and Drug Administration The FDA oversees the clinical trials for Neuralink, Musk's brain implant company, deciding whether such trials can take place and whether Neuralink can eventually sell its device to consumers. The agency already approved such trials in the U.S. Neuralink has also been pursuing clinical trials outside the U.S, including in Canada. The FDA had initially rejected Neuralink's request to start clinical trials, citing safety risks, Reuters reported in 2023. The agency has since given the startup approval to do clinical trials, which are ongoing. Environmental Protection Agency SpaceX faces environmental regulations from the EPA, which oversees the company's wastewater discharges at its operating site in Texas. The company's operations are also subject to environmental reviews under the National Environmental Policy Act, with several agencies including the Fish and Wildlife Service required to analyze the impact of the company's rocket launches and landings on land, water and wildlife. National Highway Traffic Safety Administration Tesla faces ongoing oversight from U.S. auto safety investigators about the safety of its vehicles especially when using advanced driver assistance systems. Last month, the National Highway Traffic Safety Administration asked Tesla to answer questions on its plans to launch a paid robotaxi service in Austin, Texas, in June, in order to assess how the electric vehicle maker's cars with full self-driving technology will perform in poor weather. NHTSA has been investigating Tesla's full self-driving collisions in reduced roadway visibility conditions since October. The agency said it is seeking additional information about Tesla's development of robotaxis "to assess the ability of Tesla's system to react appropriately to reduced roadway visibility conditions" as well details on robotaxi deployment plans and the technology being used. Federal Aviation Administration In September, the FAA proposed a $633,000 fine against SpaceX for failing to follow license requirements in 2023 before two launches. That investigation remains open. The FAA could also impose new restrictions or additional scrutiny after a series of explosions of SpaceX launches. Securities and Exchange Commission Musk is embroiled in litigation with the SEC over his 2022 takeover of Twitter, with Musk now due to respond to those allegations next month. The regulator also had opened an investigation into his company Neuralink according to a December letter from Musk's lawyer he posted on social media platform X. Federal Trade Commission The FTC is a consumer protection agency that ensures social media companies like Musk's platform X protect children's privacy and safeguard Americans' data. The FTC, which also enforces antitrust law, recently opened a probe into coordination between media watchdog groups, some of whom Musk has accused of orchestrating an illegal group advertiser boycott against his social media site.

A-ha frontman Morten Harket diagnosed with Parkinson's disease
Morten Harket, in an interview published on the band's website on Wednesday, said he was diagnosed several years ago and has come to terms with the neurological disease. Photo: Reuters Morten Harket, the lead singer of Norwegian band A-ha, whose Take On Me track remains one of the most popular songs from the 1980s, said on Wednesday that he had been diagnosed with Parkinson's disease. In a statement on the band's website, and confirmed by record label Sony Music, Harket, 65, said he had undergone several rounds of brain surgery and that he was managing the symptoms of the disease. Parkinson's causes deterioration in the brain's nervous system, leading to tremors and other symptoms that can become progressively worse over time. The disease can be treated with surgery and medication, but there is no cure. Harket said he last year underwent neurological procedures to have electrodes implanted inside his brain and that this had reduced the symptoms. Known for the wide range of his voice, Harket said he did not know if he would be able to perform again. "I've got no problem accepting the diagnosis," he said, adding that it was difficult to balance medication and managing side effects of the treatment. "I'm trying the best I can to prevent my entire system from going into decline," Harket said. Formed in 1982 by Harket and his friends Paul Waaktaar-Savoy and Magne Furuholmen, A-ha saw a global breakthrough in 1985 with their debut album Hunting High And Low which yielded several hits such as Take On Me and The Sun Always Shines On TV . Take On Me was recently featured in the second season of HBO's hit series The Last Of Us when the main character Ellie, played by Bella Ramsey, performed an acoustic version of the song. – Reuters

Artificial intelligence is prompting young people to rethink their career plans
Nearly 39% of young people looking for work now use artificial intelligence. — AFP Relaxnews Gone are the days when young graduates waited patiently for the doors to employment to open for them. Today, they are breaking with established norms by embracing artificial intelligence to transform their career choices. Between rapid adoption and profound upheaval, this generation is reinventing the rules of the professional game. The scale of this silent revolution can now be measured in concrete terms. A recent survey conducted by Prospects among more than 4,000 British students and graduates reveals its full scope. The results paint a picture of a generation that is embracing artificial intelligence on a massive scale, while questioning the impact of this technology on its future prospects. The figures speak for themselves. Nearly 39% of young jobseekers now use artificial intelligence to revise their resumes or cover letters, while 30% use it to write them from scratch. This widespread use of AI tools extends to preparing for job interviews (29%) and answering questions in application forms (23%). This democratization is transforming job search strategies. As a result, one-fifth of young graduates submit more than 50 applications, an increase directly linked to the ease of use of AI tools. Those aged 25-34 are the most active in this field, with 44% using artificial intelligence to optimize their chances of finding work. Rethinking career plans Beyond resumes, artificial intelligence is becoming a career advisor. Nearly 18% of respondents consult ChatGPT or Microsoft Copilot for career advice, and 84% find these platforms useful for professional guidance. AI is thus establishing itself as a legitimate source of information, even if it remains less valued than human expertise. Artificial intelligence is not only transforming job searches, it is also disrupting careers. In fact, 10% of students surveyed say they have already changed their career plans due to the emergence of this technology. Some are abandoning fields they believe are threatened by automation. "I was going to be a graphic designer, but after the big leap in AI development, I realized that most clients will no longer need my work," says one respondent. Others fear that their skills will become obsolete, particularly in translation and writing. But artificial intelligence also opens up new career prospects. Some see unprecedented opportunities in cybersecurity and data analysis. "Technology is impacting the way we deal with and respond to crime. Therefore new and emerging jobs are being created to combat it," says one individual. However, this revolution is causing anxiety. Students who have changed their career plans are more uncertain about their future (46% vs. 37%) and more pessimistic about their prospects (29% vs. 17%). "My job will be obsolete within 5 to 10 years, so I need to find something more secure now," says one respondent. This race against time creates particular stress for young people in training. Faced with this change, educational institutions and companies need to rethink their approach. The challenge is to train a generation capable of working with AI without losing their professional identity. Artificial intelligence is transforming the professional landscape, but its impact will depend on our collective ability to make it a lever for fulfillment rather than yet another source of anxiety. – AFP Relaxnews
