A newly FDA-approved form of adaptive deep-brain stimulation (DBS) for Parkinson's disease adjusts electrical stimulation in real time based on an individual's brain signals, improving symptom control and reducing medication dependence. Scientific American: For decades, Keith Krehbiel took high doses of medications with a debilitating side effect -- severe nausea -- following his diagnosis with early-onset Parkinson's disease at age 42 in 1997. When each dose wore off, he experienced dyskinesia -- involuntary, repetitive muscle movements. In his case, this consisted of head bobbing and weaving. Krehbiel is among one million Americans who live with this progressive neurological disorder, which causes slowed movements, tremors and balance problems. But soon after surgery to implant electrodes into specific areas of his brain in 2020, his life dramatically improved. "My tremor went away almost entirely," says Krehbiel, now age 70 and a professor emeritus of political science at the Stanford Graduate School of Business, whose Parkinson's symptoms began at age 40 and were initially misdiagnosed as repetitive stress injury from computer use. "I reduced my Parkinson's meds by more than two thirds," he adds. "And I no longer have a sensation of a foggy brain, nor nausea or dyskinesia." Krehbiel was the first participant to enroll in a clinical trial testing a new form of deep-brain stimulation (DBS), a technology that gained approval from the U.S. Food and Drug Administration for Parkinson's tremor and essential tremor in 1997 (it was later approved for other symptoms and conditions). The new adaptive system adjusts stimulation levels automatically based on the person's individual brain signals. In late February it received FDA approval for Parkinson's disease "based on results of the international multicenter trial, which involved participants at 10 sites across a total of four countries -- the U.S., the Netherlands, Canada and France. This technology is suitable for anyone with Parkinson's, not just individuals in clinical trials, says Helen Bronte-Stewart, the recent trial's global lead investigator and a neurologist specializing in movement disorders at Stanford Medicine. "Like a cardiac pacemaker that responds to the rhythms of the heart, adaptive deep-brain stimulation uses a person's individual brain signals to control the electric pulses it delivers," Bronte-Stewart says. "This makes it more personalized, precise and efficient than older DBS methods." "Traditional DBS delivers constant stimulation, which doesn't always match the fluctuating symptoms of Parkinson's disease," adds neurologist Todd Herrington, another of the trial's investigators and director of the deep-brain stimulation program at Massachusetts General Hospital. With adaptive DBS, "the goal is to adjust stimulation in real time to provide more effective symptom control, fewer side effects and improved patient quality of life." Current FDA approval of this adaptive system is for the treatment of Parkinson's only, not essential tremor, dystonia (a neurological disorder that causes excessive, repetitive and involuntary muscle contractions) or epilepsy, which still rely on traditional, continuous DBS, Herrington says.

An anonymous reader quotes a report from Variety: More than 400 Hollywood creative leaders signed an open letter to the Trump White House's Office of Science and Technology Policy, urging the administration to not roll back copyright protections at the behest of AI companies. The filmmakers, writers, actors, musicians and others -- which included Ben Stiller, Mark Ruffalo, Cynthia Erivo, Cate Blanchett, Cord Jefferson, Paul McCartney, Ron Howard and Taika Waititi -- were submitting comments for the Trump administration's U.S. AI Action Plan. The letter specifically was penned in response to recent submissions to the Office of Science and Technology Policy from OpenAI and Google, which asserted that U.S. copyright law allows (or should allow) allow AI companies to train their system on copyrighted works without obtaining permission from (or compensating) rights holders. "We firmly believe that America's global AI leadership must not come at the expense of our essential creative industries," the letter says in part. The letter claims that "AI companies are asking to undermine this economic and cultural strength by weakening copyright protections for the films, television series, artworks, writing, music and voices used to train AI models at the core of multibillion-dollar corporate valuations." [...] The letter says Google and OpenAI "are arguing for a special government exemption so they can freely exploit America's creative and knowledge industries, despite their substantial revenues and available funds. There is no reason to weaken or eliminate the copyright protections that have helped America flourish." You can read the full statement and list of signatories here. The letter was issued in response to recent submissions from OpenAI (PDF) and Google (PDF) claiming that U.S. law allows, or should allow, AI companies to train their programs on copyrighted works under the fair use legal doctrine.

fahrbot-bot shares a report from Reuters: BYD on Monday unveiled a new platform for electric vehicles (EVs) that it said could charge EVs as quickly as it takes to pump gas and announced for the first time that it would build a charging network across China. The so-called "super e-platform" will be capable of peak charging speeds of 1,000 kilowatts (kW), enabling cars that use it to travel 400 km (249 miles) on a 5-minute charge, founder Wang Chuanfu said at an event livestreamed from the company's Shenzhen headquarters. Charging speeds of 1,000 kW would be twice as fast as Tesla's superchargers whose latest version offers up to 500 kw charging speeds. The new charging architecture will be initially available in two new EVs -- Han L sedan and Tang L SUV priced from 270,000 yuan ($37,328.91) and BYD said it would build over 4,000 ultra-fast charging piles, or units, across China to match the new platform. "In order to completely solve our user's charging anxiety, we have been pursuing a goal to make the charging time of electric vehicles as short as the refuelling time of petrol vehicles," Wang said. "This is the first time in the industry that the unit of megawatt (charge) has been achieved on charging power," he said.

According to The Verge, legacy G Suite accounts will soon lose their individual storage allotment perks and be transitioned to pooled storage, which will be "shared across all users within your organization." The changes will come into effect starting May 1st. From the report: G Suite was rebranded as Workspace in 2020. G Suite legacy free edition, which Google stopped offering in 2012, provides each user with 15GB of free allocated storage and was offered for personal use -- making it ideal for families or groups that need to share a collective domain. Existing users have been permitted to access Workspace services at no additional charge, but Google says it's now making this change because pooled storage provides a "simpler and more flexible way to manage storage." "Google Workspace customers have had the benefit of pooled storage for years, and now we're rolling it out to users with this legacy offering," Google spokesperson Jenny Thomson told The Verge. No action is required for the switch according to Google, and users cannot opt out of the pooled storage transition. The total amount of storage allocated to the entire G Suite account won't be reduced, but if more storage is required then it can be purchased "at a discount" starting at increments of 100GB, which typically costs $15. Google hasn't specified how large this discount will be. Storage limitations can still be set for each user within the G Suite account after the transition to prevent the collective storage pool from being hogged by individual users. These limits will have to be manually assigned by an account admin, however.

Roku is testing autoplaying video ads that play before users can access the home screen. While Roku claims this is just an experiment, users are threatening to abandon the platform if the change becomes permanent. Ars Technica reports: Reports of Roku customers seeing video ads automatically play before they could view the OS' home screen started appearing online this week. A Reddit user, for example, posted yesterday: "I just turned on my Roku and got an unskippable ad for a movie, before I got to the regular Roku home screen." Multiple apparent users reported seeing an ad for the movie Moana 2. When reached for comment, a Roku spokesperson shared a company statement that confirms that the autoplaying ads are expected behavior but not a permanent part of Roku OS currently. Instead, Roku claimed, it was just trying the ad capability out. Roku's representative said that Roku's business "has and will always require continuous testing and innovation across design, navigation, content, and our first-rate advertising products," adding: "Our recent test is just the latest example, as we explore new ways to showcase brands and programming while still providing a delightful and simple user experience."

An anonymous reader quotes a report from Politico: A top Commerce Department official sent a blistering email to his former colleagues on his way out the door Sunday warning that the Trump administration is poised to unduly enrich Elon Musk's satellite internet company with money for rural broadband. The technology offered by Starlink ... is inferior, wrote Evan Feinman, who had directed the $42.5 billion broadband program for the past three years. "Stranding all or part of rural America with worse internet so that we can make the world's richest man even richer is yet another in a long line of betrayals by Washington," Feinman said. Feinman's lengthy email, totaling more than 1,100 words and shared with POLITICO, is a sign of deep discomfort about the changes underway that will likely transform the Broadband Equity, Access and Deployment Program. Commerce Secretary Howard Lutnick recently pledged a vigorous review of BEAD, with an aim to rip out what he sees as extraneous requirements and remove any preference for particular broadband technologies like fiber. The program, created in the 2021 infrastructure law program, became a source of partisan fighting last year on the campaign trail as Republicans attacked the Biden administration for its slow pace. No internet expansion projects have begun using BEAD money, although some states were close at the beginning of this year. Feinman's critique: In his email, Feinman notes Friday was his last day leading BEAD and that he's "disappointed not to be able to see this project through." Feinman's email warns the Trump administration could undermine BEAD and he encourages people to fight to retain its best aspects. Feinman said the administration should "NOT change it to benefit technology that delivers slower speeds at higher costs to the household paying the bill," adding that this isn't what rural America, congressional Republicans or Democrats, the states or the telecom industry wants. "Reach out to your congressional delegation and reach out to the Trump Administration and tell them to strip out the needless requirements, but not to strip away from states the flexibility to get the best connections for their people," Feinman wrote. He said he's not worried about the Trump administration nixing requirements around climate resiliency, labor and middle class affordability, saying those issues "were inserted by the prior administration for messaging/political purposes, and were never central to the mission of the program." Feinman warns that changes to the BEAD program under the Trump administration could stall state-level broadband progress, with Louisiana, Delaware, and Nevada already stuck in review. Meanwhile, no specific guidance or timeline for these changes has been provided, and Arielle Roth's confirmation as NTIA head is still pending in the Senate.

Google's parent company Alphabet is reportedly in talks to acquire cybersecurity startup Wiz for approximately $30 billion. Last July, negotiations had advanced on a $23 billion deal, but the talks were put on hold to prioritize Wiz's IPO. Around the same time, Alphabet also walked away from a potential acquisition of online marketing software company HubSpot. Reuters reports: The startup provides cloud-based cybersecurity solutions powered by artificial intelligence that help companies identify and remove critical risks on cloud platforms. A buyout of this size will most likely face regulatory scrutiny as tech giants are kept under close watch for possible monopolistic practices. If the deal goes through, it could help Alphabet tap into the cybersecurity industry and expand its booming cloud infrastructure segment, which generated more than $43 billion in revenue last year. Wiz was last valued at $12 billion in a private funding round in May 2024.

Apple will introduce a slimmer iPhone 17 "Air" this fall, marking a strategic shift toward potentially port-free devices in future product lines, according to a Bloomberg report. The new model will feature a 6.6-inch display with ProMotion scrolling, Dynamic Island interface, and a Camera Control button while measuring approximately 2 millimeters thinner than current models -- roughly a 20% reduction in depth, the report said. Despite its slimmer profile, the device will maintain battery life comparable to existing iPhones through redesigned display and silicon components. It will incorporate Apple's power-efficient C1 in-house modem chip but will retain USB-C connectivity, despite earlier internal discussions about eliminating ports entirely.

Most mobile apps fail to reach $1,000 in monthly revenue within their first two years, according to a new report from RevenueCat examining data from over 75,000 mobile apps. Across all categories, only about 20% of apps achieve the $1,000 threshold, while just 5% reach $10,000 monthly. In 2025, the top 5% of apps generate 500 times more revenue than the remaining 95% -- up from 200 times in 2024. After one year, elite performers in gaming, photo and video, health and fitness, and social categories exceed $5,000 monthly, while those in the 25th percentile earn a meager $5-20 per month. The report also highlights North American developers' heavy iOS dependence, with 76.1% making over 80% of their revenue from Apple's platform. Subscription retention presents another challenge, with barely 10% of monthly subscribers staying beyond the first year.

An anonymous reader quotes a report from TechCrunch: Last week, Google expanded access to its Gemini 2.0 Flash model's image generation feature, which lets the model natively generate and edit image content. It's a powerful capability, by all accounts. But it also appears to have few guardrails. Gemini 2.0 Flash will uncomplainingly create images depicting celebrities and copyrighted characters, and -- as alluded to earlier -- remove watermarks from existing photos. As several X and Reddit users noted, Gemini 2.0 Flash won't just remove watermarks, but will also attempt to fill in any gaps created by a watermark's deletion. Other AI-powered tools do this, too, but Gemini 2.0 Flash seems to be exceptionally skilled at it -- and free to use. To be clear, Gemini 2.0 Flash's image generation feature is labeled as "experimental" and "not for production use" at the moment, and is only available in Google's developer-facing tools like AI Studio. The model also isn't a perfect watermark remover. Gemini 2.0 Flash appears to struggle with certain semi-transparent watermarks and watermarks that canvas large portions of images.

Huawei will no longer be able to produce or sell Windows-based PCs as Microsoft's supply license to the Chinese tech company expires this month, according to Chinese tech site MyDrivers. The restriction comes as Huawei remains on the U.S. Department of Commerce's Entity List, requiring American companies to obtain special export licenses to conduct business with the firm. Richard Yu, executive director of Huawei's consumer business unit, said the company is preparing to pivot to alternative operating systems. Huawei had previously announced plans to abandon Windows for future PC generations. The Chinese tech giant will introduce a new "AI PC" laptop in April running its own Kunpeng CPU and HarmonyOS, alongside a MateBook D16 Linux Edition, its first Linux-based laptop.

Alphabet is spinning out Taara, a laser-based internet company from its X "moonshot" incubator, securing backing from Series X Capital while retaining a minority stake. Taara's technology transmits data at 20 gigabits per second over 20km by firing pencil-width light beams between traffic light-sized terminals, extending traditional fiber-optic networks with minimal construction costs. Based in Sunnyvale, California, the company operates in 12 countries, including India and parts of Africa, where it created a 5km laser link over the Congo River between Brazzaville and Kinshasa. The two-dozen-strong team partners with telecommunications firms like Bharti Airtel and T-Mobile to extend core fiber-optic networks to remote locations or dense urban areas. Taara originated from Project Loon, which was shut down in 2021 after facing regulatory challenges. The company is developing silicon photonic chips to replace mirrors and lenses in its terminals and potentially enable multiple connections from a single transmitter.

More than 80 signatories representing about 100 European tech organizations have urged EU leaders to take "radical action" to reduce reliance on foreign digital infrastructure, according to a letter sent to European Commission President Ursula von der Leyen. The coalition, including Airbus, Proton, and OVHCloud, warns Europe "will lose out on digital innovation" and become almost completely dependent on non-European technologies "in less than three years at current rates." The group calls for public procurement requirements mandating European-made tech solutions, development of common standards, and creation of a "Sovereign Infrastructure Fund" for capital-intensive areas like chips and quantum computing. "Our reliance on non-European technologies will become almost complete in less than three years at current rates," the letter states, citing concerns over U.S. technological dominance following recent comments from Vice President JD Vance criticizing European regulations.

Across high-income countries, humans' ability to reason and solve problems appears to have peaked in the early 2010s and declined since. Despite no changes in fundamental brain biology, test scores for both teenagers and adults show deteriorating performance in reading, mathematics and science. In an eye-opening statistic, 25% of adults in high-income countries now struggle to "use mathematical reasoning when reviewing statements" -- rising to 35% in the US. This cognitive decline coincides with a fundamental shift in our relationship with information. Americans reading books has fallen below 50%, while difficulty thinking and concentrating among 18-year-olds has climbed sharply since the mid-2010s. The timing points to our changing digital habits: a transition from finite web pages to infinite feeds, from active browsing to passive consumption, and from focused attention to constant context-switching. Research shows that intentional use of digital technologies can be beneficial, but the passive consumption dominating recent years impairs verbal processing, attention, working memory and self-regulation. Some of the cited research in the story: New PIAAC results show declining literacy and increasing inequality in many European countries â" Better adult learning is necessary; Have attention spans been declining?; Short- and long-term effects of passive and active screen time on young children's phonological memory; Efficient, helpful, or distracting?

Abstract of a paper published on National Bureau of Economic Research: This paper investigates self-reported wedges between how much people work and how much they want to work, at their current wage. More than two-thirds of full-time workers in German survey data are overworked -- actual hours exceed desired hours. We combine this evidence with a simple model of labor supply to assess the welfare consequences of tighter weekly hours limits via willingness-to-pay calculations. According to counterfactuals, the optimal length of the workweek in Germany is 37 hours. Introducing such a cap would raise welfare by .8-1.6% of GDP. The gains from a shortened workweek are largest for workers who are married, female, white collar, middle aged, and high income. An extended analysis integrates a non-constant wage-hours relationship, falling capital returns, and a shrinking tax base.

Prolonged exposure to extreme heat accelerates biological aging in older adults, increasing the risk of age-related illnesses, according to research published in Science Advances. In a nationally representative study of 3,686 U.S. adults over age 56, scientists found that long-term exposure to high heat days was associated with accelerated epigenetic aging - molecular changes that affect how genes function without altering DNA itself. Researchers from the University of Southern California discovered that individuals living in areas where heat index values regularly exceed 90F showed signs of being biologically older than those in cooler regions, even after controlling for factors like wealth, education, and lifestyle habits. Six-year cumulative heat exposure linked to as much as 2.48 years of accelerated aging in one measurement.

HR software provider Rippling has sued competitor Deel for allegedly planting a spy in its Dublin office to steal trade secrets, court documents [PDF] showed on Monday. Rippling claims the employee, identified as D.S., systematically searched internal Slack channels for competitor information, including sales leads and pitch decks. The company discovered the alleged scheme through a "honeypot" trap -- a specially created Slack channel mentioned in a letter to Deel executives. When served with a court order to surrender his phone, D.S. locked himself in a bathroom before fleeing, according to the lawsuit. "We're all for healthy competition, but we won't tolerate when a competitor breaks the law," said Vanessa Wu, Rippling's general counsel. Both companies operate multibillion-dollar HR platforms, with Rippling valued at $13.5 billion and Deel at over $12 billion.
