'Electric Plastic' Could Unleash Next-Gen Implants and Wearable Tech | | An anonymous reader quotes a report from Science Magazine: Imagine a thin wristband that monitors your steps and heartbeat like an Apple Watch. Or clothing that keeps you cool with built-in air conditioning. Or even a flexible implant that could help your heart better than a bulky pacemaker. That's the promise of a new, electrically active material researchers have created by combining short chains of amino acids called peptides with snippets of a polymer plastic. This "electric plastic," reported this month in Nature, can store energy or record information, opening the door to self-powered wearables, real-time neural interfaces, and medical implants that merge with bodies better than current tech. [...]
Samuel Stupp, a materials scientist at Northwestern University, and his colleagues thought they could improve on polyvinylidene fluoride's (PVDF) properties. The team connected peptides with small PVDF segments, which naturally assembled into long, flexible ribbons. The molecules then coalesced into bundles and aligned to form an electro-active material. "Remarkably," Stupp says, "the self-assembly process is triggered by adding water." The new material overcomes PVDF's limitations. It requires 100 times less voltage to switch polarization compared with other ferroelectric materials, making it ideal for low-power applications. And it retains its ferroelectric properties at temperatures of 110C -- about 40C higher than other PVDF materials.
Stupp's new material can store energy or information by electrically switching the polarity of each ribbon. And because the peptide on the end of each ribbon can be connected to proteins on neurons or other cells, the molecules can record the signals from the brain, heart, or other organs -- or electrically stimulate them. By using low-power techniques like ultrasound to "charge" the molecules, the material could be used to stimulate neurons as a treatment for chronic paralysis, Stupp says. Study co-author Yang Yang, an electrical power engineer at Northwestern, notes that PVDF is biocompatible, making the material a promising candidate for soft implants that could be wirelessly controlled from outside the body. Stupp's team has conducted small-scale evaluations of molecules, but scaling up will require placing water-suspended structures onto devices without altering them -- a challenge noted by chemist Frank Leibfarth. Even with this hurdle, "This advance has enabled a number of attractive properties compared to other organic polymers," he says.
Stupp added: "This paper has a much broader concept than just vinylidene fluoride. There probably are other possibilities ... that don't have fluorine." Read more of this story at Slashdot. |
UK-Based Dissident Can Sue Saudi Arabia For Alleged Spyware, Court Rules | | A judge has allowed Saudi dissident Yahya Assiri to sue the kingdom for allegedly targeting his devices with Pegasus spyware and other Israeli-made surveillance tools. Reuters reports: Yahya Assiri, a founder of the opposition National Assembly Party (NAAS) who lives in exile in Britain, alleges his electronic devices were targeted with surveillance software between 2018 and 2020. He is suing Saudi Arabia at London's High Court, saying the country used Pegasus - made by Israeli company NSO Group and sold only to nation states - and other spyware made by lesser-known Israeli firm QuaDream because of his work with dissidents.
Earlier this month, Roger Eastman, a judge in the High Court, gave Assiri permission to serve his lawsuit on the Saudi government, a step that required the court to find Assiri has an arguable case. The decision announced on Monday to allow the case to be served on Saudi Arabia in Riyadh was made on Oct. 11. Assiri said in a statement: "I am fully aware that the authorities will want to target me. However, it is outrageous for them also to target individuals such as the victims of rights abuses and their families in Saudi Arabia simply because these people have been in contact with me."

San Francisco Muni's Rail System Will Spend $212 Million To Upgrade From Floppy Disks | | San Francisco's Municipal Transportation Agency approved a $212 million contract with Hitachi Rail to modernize the Muni Metro system's outdated train control system, which currently uses floppy disks and wire loops. Government Technology reports: The software that runs the system is stored on floppy disks that are loaded each morning and an outdated type of communication using wire loops that are easily disrupted. It was expected to last for 20 to 25 years, according to Muni officials. It moves data more slowly than a wireless modem, they said. By late 2027 and into 2028, a new communications-based system, which employs Wi-Fi and cell signals to precisely track the locations of trains, will be installed by Hitachi, which will provide support services for 20 years under the agreement.
While the current train control system operates only on the Market Street subway and Central Subway, the new system will control Metro light rail trains on the system's surface lines as well. The Hitachi system is said to be five generations ahead of the current system, said Muni Director of Transit Julie Kirschbaum, who described it as the best train control system on the market.

Lawsuit Argues Warrantless Use of Flock Surveillance Cameras Is Unconstitutional | | A civil liberties group has filed a lawsuit in Virginia arguing that the widespread use of Flock's automated license plate readers violates the Fourth Amendment's protections against warrantless searches. 404 Media reports: "The City of Norfolk, Virginia, has installed a network of cameras that make it functionally impossible for people to drive anywhere without having their movements tracked, photographed, and stored in an AI-assisted database that enables the warrantless surveillance of their every move. This civil rights lawsuit seeks to end this dragnet surveillance program," the lawsuit notes (PDF). "In Norfolk, no one can escape the government's 172 unblinking eyes," it continues, referring to the 172 Flock cameras currently operational in Norfolk. The Fourth Amendment protects against unreasonable searches and seizures and has been ruled in many cases to protect against warrantless government surveillance, and the lawsuit specifically says Norfolk's installation violates that. [...]
The lawsuit in Norfolk is being filed by the Institute for Justice, a civil liberties organization that has filed a series of privacy and government overreach lawsuits over the last few years. Two Virginia residents, Lee Schmidt and Crystal Arrington, are listed as plaintiffs in the case. Schmidt is a Navy veteran who alleges in the lawsuit that the cops can easily infer where he is going based on Flock data. "Just outside his neighborhood, there are four Flock Cameras. Lee drives by these cameras (and others he sees around town) nearly every day, and the Norfolk Police Department [NPD] can use the information they record to build a picture of his daily habits and routines," the lawsuit reads. "If the Flock Cameras record Lee going straight through the intersection outside his neighborhood, for example, the NPD can infer that he is going to his daughter's school. If the cameras capture him turning right, the NPD can infer that he is going to the shooting range. If the cameras capture him turning left, the NPD can infer that he is going to the grocery store. The Flock Cameras capture the start of nearly every trip Lee makes in his car, so he effectively cannot leave his neighborhood without the NPD knowing about it." Arrington is a healthcare worker who makes home visits to clients in Norfolk. The lawsuit alleges that it would be trivial for the government to identify her clients. "Fourth Amendment case law overwhelmingly shows that license plate readers do not constitute a warrantless search because they take photos of cars in public and cannot continuously track the movements of any individual," a Flock spokesperson said. "Appellate and federal district courts in at least fourteen states have upheld the use of evidence from license plate readers as Constitutional without requiring a warrant, as well as the 9th and 11th circuits. Since the Bell case, four judges in Virginia have ruled the opposite way -- that ALPR evidence is admissible in court without a warrant." Read more of this story at Slashdot. |
Peter Todd In Hiding After Being 'Unmasked' As Bitcoin Creator Satoshi Nakamoto | | An anonymous reader quotes a report from Wired: When Canadian developer Peter Todd found out that a new HBO documentary, Money Electric: The Bitcoin Mystery, was set to identify him as Satoshi Nakamoto, the creator of Bitcoin, he was mostly just pissed. "This was clearly going to be a circus," Todd told WIRED in an email. The identity of the person -- or people -- who created Bitcoin has been the subject of speculation since December 2010, when they disappeared from public view. The mystery has proved all the more irresistible for the trove of bitcoin Satoshi is widely believed to have controlled, suspected to be worth many billions of dollars today. When the documentary was released on October 8, Todd joined a long line of alleged Satoshis.
Documentary maker Cullen Hoback, who in a previous film claimed to have identified the individual behind QAnon, laid out his theory to Todd on camera. The confrontation would become the climactic scene of the documentary. But Todd nonetheless claims he didn't see it coming; he alleges he was left with the impression the film was about the history of Bitcoin, not the identity of its creator. Since the documentary aired, Todd has repeatedly and categorically denied that he created Bitcoin: "For the record, I am not Satoshi," he alleges. "I think Cullen made the Satoshi accusation for marketing. He needed a way to get attention for his film."
For his part, Hoback remains confident in his conclusions. The various denials and deflections from Todd, he claims, are part of a grand and layered misdirection. "While of course we can't outright say he is Satoshi, I think that we make a very strong case," says Hoback. Whatever the truth, Todd will now bear the burden of having been unmasked as Satoshi. He has gone into hiding. [...] Todd expects that "continued harassment by crazy people" will become the indefinite status quo. But he says the potential personal safety implications are his chief concern -- and the reason he has gone into hiding. "Obviously, falsely claiming that ordinary people of ordinary wealth are extraordinarily rich exposes them to threats like robbery and kidnapping," says Todd. "Not only is the question dumb, it's dangerous. Satoshi obviously didn't want to be found, for good reasons, and no one should help people trying to find Satoshi." "I think the idea that it puts their life [at risk] is a little overblown," says Hoback. "This person is potentially on track to become the wealthiest on Earth."
"If countries are considering adopting this in their treasuries or making it legal tender, the idea that there's potentially this anonymous figure out there who controls one twentieth of the total supply of digital gold is pretty important." Read more of this story at Slashdot. |

Air Taxis and Other Electric-Powered Aircraft Cleared For Takeoff | | The FAA has released final regulations for electric vertical takeoff and landing (eVTOL) vehicles, introducing a new category of aircraft for the first time in nearly 80 years. These rules provide a framework for pilot training and operational requirements, addressing industry concerns while aiming to support the future of advanced air mobility. The Verge reports: The FAA says these âoepowered-liftâ vehicles will be the first completely new category of aircraft since helicopters were introduced in 1940. These aircraft will be used for a variety of services, including air taxis, cargo delivery, and rescue and retrieval operations. The final rules published today contain guidelines for pilot training as well as operational requirements regarding minimum safe altitudes and visibility. [...] Powered lift includes aircraft described by industry watchers as electric vertical takeoff and landing, or eVTOL. Using tilt rotors, eVTOL aircraft are designed to take off and land vertically like a helicopter and then transition into forward flight on fixed wings like a plane.
[...] A new pilot training and qualifications rule was needed because âoeexisting regulations did not address this new category of aircraft, which can take off and land vertically like a helicopter and fly like an airplane during cruise flight,â the FAA said. The rule also provides a âoecomprehensive frameworkâ for certifying the initial group of powered-lift instructors and pilots. According to the agency, the rule would: "Makes changes to numerous existing regulations and establishes a Special Federal Aviation Regulation (SFAR) with new requirements to facilitate instructor and pilot certification and training. Applies helicopter operating requirements to some phases of flight and adopts a performance-based approach to certain operating rules. Allows pilots to train in powered-lift with a single set of flight controls; legacy rules require two flight controls -- one for the student and one for the instructor." "The regulation published today will ensure the U.S. continues to play a global leadership role in the development and adoption of clean flight," said JoeBen Bevirt, founder and CEO of Joby, in a statement. "Delivering the rules ahead of schedule is testament to the dedication, coordination and hard work of the rulemaking team." Read more of this story at Slashdot. |
Qualcomm Brings Laptop-Class CPU Cores To Phones With Snapdragon 8 Elite | | An anonymous reader quotes a report from Ars Technica: Qualcomm has a new chip for flagship phones, and the best part is that it uses an improved version of the Oryon CPU architecture that the Snapdragon X Elite chips brought to Windows PCs earlier this year. The Snapdragon 8 Elite is the follow-up to last year's Snapdragon 8 Gen 3 -- yet another change to the naming convention that Qualcomm uses for its high-end phone chips, though, as usual, the number 8 is still involved. The 8 Elite uses a "brand-new, 2nd-generation Qualcomm Oryon CPU" with clock speeds up to 4.32 GHz, which Qualcomm says will improve performance by about 45 percent compared to the Snapdragon 8 Gen 3.
Rather than a mix of large, medium, and small CPU cores as it has used in the past, the 8 Elite has two "Prime" cores for hitting that high peak clock speed, while the other six are all "Performance" cores that peak at a lower 3.53 GHz. But it doesn't look like Qualcomm is using a mix of different CPU architectures anymore, choosing to distinguish the higher-performing core from the lower-performing ones by clock speed alone. Qualcomm promises a similar 40 percent performance boost from the new Adreno 830 GPU. The chip also includes a marginally improved Snapdragon X80 5G modem, up from an X75 modem in the Snapdragon 8 Gen 3 -- its main improvement appears to be support for additional antennas, for a total of six, but the download speed still tops out at a theoretical 10Gbps. Wi-Fi 7 support appears to be the same as in the 8 Gen 3, but the 8 Elite does support the Bluetooth 6.0 standard, up from Bluetooth 5.4 in the 8 Gen 3.
Qualcomm says the new chip's CPU features "44% improved power efficiency" and "40% greater power efficiency" for the GPU, which ought to keep power usage in line despite the performance improvements -- these gains are probably attributable to the new 3 nm TSMC manufacturing process, compared to the 4 nm process used for the Snapdragon 8 Gen 3. And no 2024 chip announcement would be complete without some kind of AI mention: Qualcomm's image signal processor is now an "AI ISP," which Qualcomm says "recognizes and enhances virtually anything in the frame, including faces, hair, clothing, objects, backgrounds, and beyond." These capabilities can allow it to remove objects from the background of photos, among other things, using the on-device processing power of the chip's Hexagon neural processing unit (NPU). The NPU is 45 percent faster than the one in the Snapdragon 8 Gen 3. Phones using the Snapdragon 8 Elite should begin appearing in "the coming weeks." Read more of this story at Slashdot. |
Comic Sans Got the Last Laugh | | On July 4, 2012, CERN physicist Fabiola Gianotti announced a major quantum field theory discovery using a PowerPoint presentation in Comic Sans, sparking both mockery and debate. The font, created by Vincent Connare for Microsoft Bob in 1994, featured deliberately imperfect letters inspired by comic books. Comic Sans shipped with Windows 95 and exploded in popularity as personal computing democratized typography. A backlash emerged as the font appeared on everything from funeral notices to museum signs, culminating in Dave and Holly Combs's "Ban Comic Sans" campaign. Read more of this story at Slashdot. |
More Than 10,500 Artists Unite in Fight Against AI Companies' 'Unjust' Use of Creative Works | | More than 10,500 artists and creators -- including ABBA's Bjorn Ulvaeus, actress Julianne Moore, actors Kevin Bacon and F. Murray Abraham, as well as former Saturday Night Live star Kate McKinnon, author James Patterson and Radiohead's Thom Yorke -- signed a statement condemning AI companies' unauthorized use of creative works for training their models. The initiative, led by former AI executive Ed Newton-Rex, demands an end to unlicensed training data collection amid mounting legal challenges against tech firms. "The unlicensed use of creative works for training generative AI is a major, unjust threat to the livelihoods of the people behind those works, and must not be permitted," reads the statement.
The protest comes as major artists and publishers battle AI developers in court. Authors John Grisham and George R.R. Martin are suing OpenAI, while record labels Universal, Sony and Warner have filed lawsuits against AI music creators Suno and Udio. The signatories reject proposed "opt-out" schemes for content scraping, calling instead for explicit creator consent. Read more of this story at Slashdot. |
UK Considers New Smartphone Bans for Children | | The UK parliament is considering clamping down on how young people use smartphones. A bill brought forward by a Labour member of parliament proposes both banning phones in schools and raising the age at which children can consent to social media companies using their data. Wired: Calls for smartphone bans have been growing in the UK, driven by fears that the devices are driving a decline in kids' mental health and ability to focus. Smartphone Free Childhood, a prominent pressure group inspired by Jonathan Haidt's book The Anxious Generation, calls for parents to delay getting smartphones for their children until they are at least 13. Florida has already passed a law that bans under-14s from holding social media accounts, and Australia is considering similar restrictions.
But academics warn that smartphone and social media bans are unlikely to be a catch-all solution to the problems facing young people. Experts on the impact of digital technologies argue that the legislation could end up shutting children out from the potential benefits of smartphones, and that more pressure should be put on social media companies to design better digital worlds for children. The latest proposed clampdown in the UK is thin on details, but the MP bringing the bill, Josh MacAllister, told the radio show Today that it would prevent social media companies making use of young peoples' data until they are 16. "We can protect children from lots of the addictive bad design features that come from social media," he said. The bill would also make a ban on phones in schools legally binding.

Netflix Closes AAA Game Studio Before It Ever Released a Game | | The first cracks are starting to show in Netflix's push into gaming. The Verge: First reported in Game File and confirmed by Netflix, the streaming company has quietly closed of one of its studios, the first in the three years since the company began its foray into gaming.
According to Game File, the shuttered studio was known as Blue. In 2022, Netflix announced it hired former Overwatch executive producer Chacko Sonny to run the studio. Since then, Blue had brought on a number of game industry veterans with experience working on high profile franchises including Halo and God of War. Reportedly, Blue was developing a multi-platform AAA game for an original IP but was closed before the game could be announced or released. Read more of this story at Slashdot. |
EVs Are Just Going To Win | | An anonymous reader shares a post: EVs are still winning. But they haven't won yet; only 4% of the global passenger car fleet, 23% of the bus fleet, and less than 1% of delivery trucks are electrified.
But at this point I think the writing is on the wall. The phenomenon of a superior technology displacing an older, inferior technology is not uncommon, and it generally looks like the EV transition is looking now. When a new technology passes a 5% adoption rate, it almost never turns out to be inferior to what came before; with EVs, that threshold has now been reached in dozens of countries.
In fact, we don't have to rely on trend-based forecasting to understand why EVs are just going to win. There are a number of fundamental factors that make EVs simply better than combustion vehicles. The longer time goes on, the more these inherent advantages will make themselves felt in the market.
The first of these is price. Currently, EVs often require government subsidies in order to be price-competitive with combustion cars. But batteries are getting cheaper and cheaper as we get better and better at building them. The cheaper batteries get, the smaller the subsidies required to get people to switch to EVs. Goldman Sachs reports that this crucial tipping point will be reached in about two years:
[...] Once batteries cross that tipping point, the EV revolution will take on its own momentum. It will simply be cheaper to buy an EV than a combustion car. People will gravitate toward the cheaper option, especially if it comes with other advantages. And in this case it does.
EVs' second advantage is convenience. Most EV owners will almost never have to fill their cars up at a station. This is because they will charge their cars at night, in their own home garages or driveway. Read more of this story at Slashdot. |
'Operating in the Stone Age': NHS Staff's Daily Struggle With Outdated Tech | | The Financial Times: In the paediatric centre at one of London's largest hospitals, doctors are confounded each day by a ward computer that is not connected to a printer. The computer is used for managing the daily list of patients. Doctors can only access and update the list, using one shared account. So twice a day, two doctors on the ward said one of them had to log in to this computer, update the patient list, send the list to themselves via NHS email, and then log in to another nearby computer to print it off for the team. "I am at a top London hospital and yet at times I feel as though we are operating in the Stone Age," said one paediatrician on the ward.
Tackling the frustrating delays caused by outdated technology [Editor's note: non-paywalled link] is one of health secretary Wes Streeting and Prime Minister Sir Keir Starmer's core missions, having vowed to shift the service "from an analogue to a digital NHS." The monumental task of moving the world's largest publicly funded health service into the digital age is not lost on doctors working on the frontline of the NHS. While many sectors of the economy have been "radically reshaped" by technology in recent years, a landmark report into the state of the health service in England last month concluded that the NHS stood "in the foothills of digital transformation."
But doctors and nurses point out that the basic infrastructure needs to be brought up to a minimum standard, given significant regional variations between hospitals, before politicians extol the virtues of cutting-edge tech. "Some of us just want the printers to work," noted one NHS hospital doctor. "The complete flip-a-coin nature of how equipped your hospital is is mind-boggling," they added. "I have worked in hospitals that are at least 12 years behind others." A report published in 2022 by the British Medical Association, the UK's main doctors' union, estimated that doctors in England lost 13.5mn working hours a year as a consequence of "inadequate IT systems and equipment." One reason for the outdated infrastructure is that the country has spent almost $48bn less than its peers -- such as Germany, France, Australia -- on health assets since the 2010s, according to a government-commissioned study by Lord Ara Darzi last month.

FTC's Rule Banning Fake Online Reviews Goes Into Effect | | A federal rule banning fake online reviews is now in effect. The Federal Trade Commission issued the rule in August banning the sale or purchase of online reviews. The rule, which went into effect Monday, allows the agency to seek civil penalties against those who knowingly violate it. AP: "Fake reviews not only waste people's time and money, but also pollute the marketplace and divert business away from honest competitors," FTC Chair Lina Khan said about the rule in August. She added that the rule will "protect Americans from getting cheated, put businesses that unlawfully game the system on notice, and promote markets that are fair, honest, and competitive."
