Recent research led by the University of California, Irvine has discovered warm, high-pressure seawater causing significant melting under the Thwaites Glacier in Antarctica. "There are places where the water is almost at the pressure of the overlying ice, so just a little more pressure is needed to push up the ice," said lead author Eric Rignot, UC Irvine professor of Earth system science. "The water is then squeezed enough to jack up a column of more than half a mile of ice." Interesting Engineering reports: A team of glaciologists led by researchers at the University of California, Irvine employed high-resolution satellite radar data to uncover evidence of the warm, high-pressure seawater intrusion beneath the glacier. A statement by the scientists noted that the widespread contact between ocean water and the glacier -- a process replicated throughout Antarctica and in Greenland -- causes "vigorous melting" and may require a reassessment of global sea level rise projections. In a bid to comprehend the impact of ocean-water interaction on glacial melting, glaciologists examined data collected between March 2023 and June 2023 sourced from Finland's ICEYE commercial satellite mission. These satellites represent a collection that resembles constellations in polar orbit around the planet. They employ InSAR -- interferometric synthetic aperture radar -- to continuously track changes on the Earth's surface. "When we have a continuous time series and compare that with the tidal cycle, we see the seawater coming in at high tide and receding and sometimes going farther up underneath the glacier and getting trapped," said Rignot. "Thanks to ICEYE, we're beginning to witness this tidal dynamic for the first time." He explained that seawater entering the base of the ice sheet, along with freshwater from geothermal heat and friction, accumulates and needs to flow. This water moves through natural channels or pools in cavities, creating pressure that lifts the ice sheet. Co-author Christine Dow, professor in the Faculty of Environment at the University of Waterloo in Ontario, Canada alluding to the glacier in question said that the Thwaites is the most unstable place in the Antarctic and contains the equivalent of 60 centimeters of sea level rise. The worry is that we are underestimating the speed at which the glacier is changing, which would be devastating for coastal communities around the world. "At the moment we don't have enough information to say one way or the other how much time there is before the oceanwater intrusion is irreversible, says Dow. The study was published in the journal Proceedings of the National Academy of Sciences.

The FDA has approved Neuralink to implant its brain chip in a second patient. According to the Wall Street Journal, the company also outlined fixes to an electrode problem that caused its chip to detach from the first patient's brain. They were unharmed and could still control a computer mouse using their thoughts. Axios reports: Neuralink, which is owned by Elon Musk, said it is seeking applications for another patient with quadriplegia to test if the device can allow a person to do tasks like control a phone and computer. It outlined fixes that included embedding some of the device's wiring deeper into the brain, the Wall Street Journal reported, citing a document and a person familiar with the company. Neuralink rival Synchron is preparing a large-scale clinical trial with an eye toward seeking commercial approval of its implant. Mass General Brigham has also launched a collaborative effort with stakeholders and the FDA to accelerate the development of the implanted devices.

An anonymous reader quotes a report from Medical Xpress: A team of medical researchers at the National Children's Medical Center, Children's Hospital, Fudan University, in China, has developed a technique to freeze and thaw brain tissue without causing damage. In their study, published in the journal Cell Reports Methods, the group tested bathing brain organoid tissue in candidate chemicals before freezing them using liquid nitrogen. [...] The work involved dipping or soaking brain organoids (brain tissue grown from stem cells) in candidate compounds and then freezing and thawing them to see how they fared. After many attempts, they found one combination of solutions that worked best -- a mix of ethylene glycol, methylcellulose DMSO and Y27632. They named the solution mix MEDY. The research team then tested MEDY under a variety of conditions to see how well it prevented damage from freezing. The conditions involved changing variables, such as the age of the organoids prior to freezing and how long they were soaked in a MEDY solution. They then allowed the organoids to resume growing after they were thawed for up to 150 days. The researchers found little difference between organoids that had been frozen and those that had not -- even those that had been frozen for as long as 18 months. As a final test, the research team used their technique on a sample of brain tissue obtained from a live human patient and found that it worked just as well.

In a new blog post, Ethereum co-founder Vitalik Buterin has shared his thoughts on three issues core to Ethereum's decentralization: MEV, liquid staking, and the hardware requirements of nodes. The Block reports: In his post, published on May 17, Buterin first addresses the issue of MEV, or the financial gain that sophisticated node operators can capture by reordering the transactions within a block. Buterin characterizes the two approaches to MEV as "minimization" (reducing MEV through smart protocol design, such as CowSwap) and "quarantining" (attempting to reduce or eliminate MEV altogether through in-protocol techniques). While MEV quarantining seems like an alluring option, Buterin notes that the prospect comes with some centralization risks. "If builders have the power to exclude transactions from a block entirely, there are attacks that can quite easily arise," Buterin noted. However, Buterin championed the builders working on MEV quarantining through concepts like transaction inclusion lists, which "take away the builder's ability to push transactions out of the block entirely." "I think ideas in this direction - really pushing the quarantine box to be as small as possible - are really interesting, and I'm in favor of going in that direction," Buterin concluded. Buterin also addressed the relatively low number of solo Ethereum stakers, as most stakers choose to stake with a staking provider, either a centralized offering like Coinbase or a decentralized offering like Lido or RocketPool, given the complexity, hardware requirement, and 32 eth minimum needed to operate an Ethereum node solo. While Buterin acknowledges the progress being made to reduce the cost and complexity around running a solo node, he also noted "once again there is more that we could do," perhaps through reducing the time to withdraw staked ether or reducing the 32 eth minimum requirement to become a solo staker. "Incorrect answers could lead Ethereum down a path of centralization and 're-creating the traditional financial system with extra steps'; correct answers could create a shining example of a successful ecosystem with a wide and diverse set of solo stakers and highly decentralized staking pools," Buterin wrote. [...] Buterin finished his post by imploring the Ethereum ecosystem to tackle the hard questions rather than shy away from them. "...We should have deep respect for the properties that make Ethereum unique, and continue to work to maintain and improve on those properties as Ethereum scales," Buterin wrote. Buterin added today, in a post on X, that he was pleased to see civil debate among community members. "I'm really proud that ethereum does not have any culture of trying to prevent people from speaking their minds, even when they have very negative feelings toward major things in the protocol or ecosystem. Some wave the ideal of 'open discourse' as a flag, some take it seriously," Buterin wrote.

Apple is offering discounts of up to $318 on select iPhone models in China, hoping to "defend its position in the high-end smartphone market, where it faces increasing competition from local rivals such as Huawei," reports Reuters. From the report: The increased competitive pressure on Apple comes after Huawei last month introduced its new series of high-end smartphones, the Pura 70, following the launch of the Mate 60 last August. Apple's previous discounting effort in February appears to have helped the company mitigate a sales slowdown in China. Apple's shipments in China increased by 12% in March, according to Reuters' calculations based on data from the China Academy of Information and Communications Technology (CAICT). This marks a significant improvement from the first two months of 2024, when the company experienced a 37% slump in sales.

HP announced today that it will resurrect the "Omni" branding it first coined for its business-oriented laptops introduced in 1993. The vintage branding will now be used for the company's new consumer-facing laptops, with HP retiring the Spectre and Dragonfly brands in the process. Furthermore, computers under consumer PC series names like Pavilion will also no longer be released. "Instead, every consumer computer from HP will be called either an OmniBook for laptops, an OmniDesk for desktops, or an OmniStudio for AIOs," reports Ars Technica. From the report: The computers will also have a modifier, ranging from 3 up to 5, 7, X, or Ultra to denote computers that are entry-level all the way up to advanced. For instance, an HP OmniBook Ultra would represent HP's highest-grade consumer laptop. "For example, an HP OmniBook 3 will appeal to customers who prioritize entertainment and personal use, while the OmniBook X will be designed for those with higher creative and technical demands," Stacy Wolff, SVP of design and sustainability at HP, said via a press announcement today. [...] So far, HP has announced one new Omni computer, the OmniBook X. It has a 12-core Snapdragon X Elite X1E-78-100, 16GB or 32GB of MPDDR5x-8448 memory, up to 2TB of storage, and a 14-inch, 2240x1400 IPS display. HP is pointing to the Latin translation of omni, meaning "all" (or everything), as the rationale behind the naming update. The new name should give shoppers confidence that the computers will provide all the things that they need. HP is also getting rid of some of its commercial series names, like Pro. From now on, new, lower-end commercial laptops will be ProBooks. There will also be ProDesktop desktops and ProStudio AIOs. These computers will have either a 2 modifier for entry-level designs or a 4 modifier for ones with a little more power. For example, an HP ProDesk 2 is less powerful than an HP ProDesk 4. Anything more powerful will be considered either an EliteBook (laptops), EliteDesk (desktops), or EliteStudio (AIOs). For the Elite computers, the modifiers go from 6 to 8, X, and then Ultra. A Dragonfly laptop today would fall into the Ultra category. HP did less overhauling of its commercial lineup because it "recognized a need to preserve the brand equity and familiarity with our current sub-brands," Wolff said, adding that HP "acknowledged the creation of additional product names like Dragonfly made those products stand out, rather than be seen as part of a holistic portfolio." [...] As you might now expect of any tech rebranding, marketing push, or product release these days, HP is also announcing a new emblem that will appear on its computers, as well as other products or services, that substantially incorporate AI. The two laptops announced today carry the logo. According to Wolff, on computers, the logo means that the systems have an integrated NPU "at 40+ trillions of operations per second." They also come with a chatbot based on ChatGPT 4, an HP spokesperson told me.

An anonymous reader quotes a report from The Hill: In the wake of the COVID-19 pandemic, the dynamics of the workplace have undergone a seismic shift. While some heralded the return to the office as a sign of normalcy, evidence suggests that for many, this transition has been far from smooth sailing. Nowhere is this struggle more evident than in the case of the U.S. federal government employees, particularly those within the Department of Justice. At the beginning of the year, the Justice Department initiated a return-to-office policy requiring much of its workforce to be present in person for up to six days per pay period or about three days per week. However, there were more stringent requirements for assistant U.S. attorneys. While approximately 70 percent of AUSAs currently enjoy the flexibility of two days per week of telework, recent changes in telework policies within certain offices have left many feeling stranded. A survey by the National Association of Assistant U.S. Attorneys (NAAUSA) reveals a stark contrast in job satisfaction between those with telework options and those without. In offices where routine telework has been curtailed, a staggering 81 percent of respondents admitted they were actively seeking alternative employment opportunities. This dissatisfaction stands in contrast to offices where some level of telework is maintained, where only 42 percent of respondents expressed a desire to leave their current positions. NAAUSA Vice President Adam Hanna aptly summarizes the situation as a "workforce revolt." It's a sentiment echoed by employees across various offices, underscoring the critical importance of telework in retaining talent and maintaining morale. This is yet another testament to the value placed on flexibility and work-life balance -- crucial factors in the recruitment and retention of top talent. In response to the survey findings, NAAUSA has urged Justice Department leadership to implement consistent telework policies across all offices. The organization recommends a minimum baseline of two telework days per week, citing the importance of treating employees as responsible professionals capable of balancing in-person and remote work effectively. The issue extends beyond individual preferences, resonating with broader concerns surrounding recruitment, retention, and workplace culture. Employee organizations within the Justice Department have united in calling for a review of return-to-office mandates, citing potential negative impacts on productivity and workforce retention. These findings align with broader evidence of telework's positive effects, including the Office of Personnel Management's annual report (PDF) about telework in the federal government. That report showed that a staggering 68 percent of teleworking federal government employees intend to remain in their current positions, in contrast to a mere 53 percent of non-telecommuters. This underscores the pivotal role of telework in fostering employee loyalty and commitment.

With JPMorgan and Mastercard piloting biometric payment options, a future where consumers can pay with their face is rapidly approaching. "Our focus on biometrics as a secure way to verify identity, replacing the password with the person, is at the heart of our efforts in this area," said Dennis Gamiello, executive vice president of identity products and innovation at Mastercard. Based on the positive feedback received thus far, Gamiello says the biometric checkout technology will roll out to more new markets later this year. CNBC reports: Biometric payment options are becoming more common. Amazon introduced pay-by-palm technology in 2020, and while its cashier-less store experiment has faltered, it installed the tech in 500 of its Whole Foods stores last year. Mastercard, which is working with PopID, launched a pilot for face-based payments in Brazil back in 2022, and it was deemed a success -- 76% of pilot participants said they would recommend the technology to a friend. Late last year, Mastercard said it was teaming with NEC to bring its Biometric Checkout Program to the Asia-Pacific region. A deal that PopID recently signed with JPMorgan is a sign of things to come in the U.S., said John Miller, PopID CEO, and what he thinks will be a "breakthrough" year for pay-by-face technology. The consumer case is tied to the growing importance of loyalty programs. Most quick-service restaurants require consumers to provide their loyalty information to earn rewards -- which means pulling out a phone, opening an app, finding the link to the loyalty QR code, and then presenting the QR code to the cashier or reader. For payment, consumers are typically choosing between pulling out their wallet, selecting a credit card, and then dipping or tapping the card or pulling out their phone, opening it with Face ID, and then presenting it to the reader. Miller says PopID simplifies this process by requiring just tapping an on-screen button, and then looking briefly at a camera for both loyalty check-in and payment. "We believe our partnership with JPMorgan is a watershed moment for biometric payments as it represents the first time a leading merchant acquirer has agreed to push biometric payments to its merchant customers," Miller said. "JPMorgan brings the kind of credibility and assurance that both merchants and consumers need to adopt biometric payments." Juniper Research forecasts over 100% market growth for global biometric payments between 2024 and 2028, and by 2025, $3 trillion in mobile, biometric-secured payments. Sheldon Jacobson, a professor in computer science at the University of Illinois, Urbana-Champaign, said he sees biometric identification as part of a technology continuum that has evolved from payment with a credit card to smartphones. "The next natural step is to simply use facial recognition," he said.

An anonymous reader quotes a report from Ars Technica: Microsoft is going all-in on Arm-powered Windows PCs today with the introduction of a Snapdragon X Elite-powered Surface Pro convertible and Surface Laptop, and there are inevitable comparisons to draw with another big company that recently shifted from Intel's processors to Arm-based designs: Apple. A huge part of the Apple Silicon transition's success was Rosetta 2, a translation layer that makes it relatively seamless to run most Intel Mac apps on an Apple Silicon Mac with no extra effort required from the user or the app's developer. Windows 11 has similar translation capabilities, and with the Windows 11 24H2 update, that app translation technology is getting a name: Prism. Microsoft says that Prism isn't just a new name for the same old translation technology. Translated apps should run between 10 and 20 percent faster on the same Arm hardware after installing the Windows 11 24H2 update, offering some trickle-down benefits that users of the handful of Arm-based Windows 11 PCs should notice even if they don't shell out for new hardware. The company says that Prism's performance should be similar to Rosetta's, though obviously this depends on the speed of the hardware you're running it on. Microsoft also claims that Prism will further improve the translation layer's compatibility with x86 apps, though the company didn't get into detail about the exact changes it had made on this front.

An anonymous reader shares a report: Google is pouncing on Microsoft's weathered enterprise security reputation by pitching its services to government institutions. Pointing to a recent report from the US Cyber Safety Review Board (CSRB) that found that Microsoft's security woes are the result of the company "deprioritizing" enterprise security, Google says it can help. The company's pitch isn't quite as direct as Microsoft CEO Satya Nadella saying he made Google dance, but it's spicy all the same. Repeatedly referring to Microsoft as "the vendor" throughout its blog post on Monday, Google says the CSRB "showed that lack of a strong commitment to security creates preventable errors and serious breaches." Platforms, it added, "have a responsibility" to hold to strong security practices. And of course, who is more responsible than Google?

An anonymous reader shares a report: Hims & Hers Health, one of the online pharmacies that got its start prescribing dick pills, is now offering knockoff versions of GLP-1 weight loss drugs. Hims & Hers says it will offer drugs that mimic Ozempic and Wegovy, the active ingredient of which is semaglutide. The copycat versions are made by compounding pharmacies. The formulations aren't the same as the FDA-approved versions of the drug and haven't been directly evaluated by the FDA, either. But they're cheaper than the real thing: $199 a month, compared to the branded version, which can cost more than $1,000 a month without insurance. Compounding pharmacies can make knockoff versions of branded drugs when they are in shortage, as the GLP-1 drugs -- prescribed for diabetes and weight loss -- currently are. The FDA has already received reports of adverse events for compounded versions of semaglutide. Hims & Hers says it "conducted extensive research for over a year" into finding a supplier, but does not name the one it chose to partner with. "Over the last year, we have grown in our conviction -- based on our medical experts' evaluation and the strength of our infrastructure -- that if done properly, compounded GLP-1s are safe and effective," the company said in its statement.

Microplastics have been found in human testicles, with researchers saying the discovery might be linked to declining sperm counts in men. From a report: The scientists tested 23 human testes, as well as 47 testes from pet dogs. They found microplastic pollution in every sample. The human testicles had been preserved and so their sperm count could not be measured. However, the sperm count in the dogs' testes could be assessed and was lower in samples with higher contamination with PVC. The study demonstrates a correlation but further research is needed to prove microplastics cause sperm counts to fall. Sperm counts in men have been falling for decades, with chemical pollution such as pesticides implicated by many studies. Microplastics have also recently been discovered in human blood, placentas and breast milk, indicating widespread contamination of people's bodies. The impact on health is as yet unknown but microplastics have been shown to cause damage to human cells in the laboratory. Vast amounts of plastic waste are dumped in the environment and microplastics have polluted the entire planet, from the summit of Mount Everest to the deepest oceans. People are known to consume the tiny particles via food and water as well as breathing them in. The particles could lodge in tissue and cause inflammation, as air pollution particles do, or chemicals in the plastics could cause harm. In March, doctors warned of potentially life-threatening effects after finding a substantially raised risk of stroke, heart attack and earlier death in people whose blood vessels were contaminated with microscopic plastics.

An Australian computer scientist who claimed he invented bitcoin lied "extensively and repeatedly" and forged documents "on a grand scale" to support his false claim, a judge at London's High Court ruled on Monday. From a report: [...] Judge James Mellor ruled in March that the evidence Craig Wright was not Satoshi was "overwhelming", after a trial in a case brought by the Crypto Open Patent Alliance (COPA) to stop Wright suing bitcoin developers. Mellor gave reasons for his conclusions on Monday, stating in a written ruling: "Dr Wright presents himself as an extremely clever person. However, in my judgment, he is not nearly as clever as he thinks he is." The judge added: "All his lies and forged documents were in support of his biggest lie: his claim to be Satoshi Nakamoto."

OpenAI is pausing the use of the popular Sky voice in ChatGPT over concerns it sounds too much like the "Her" actress Scarlett Johansson. From a report: The company says the voices in ChatGPT were from paid voice actors. A final five were selected from an initial pool of 400 and it's purely a coincidence the unnamed actress behind the Sky voice has a similar tone to Johansson. Voice is about to become more prominent for OpenAI as it begins to roll out a new GPT-4o model into ChatGPT. With it will come an entirely new conversational interface where users can talk in real-time to a natural-sounding and emotion-mimicking AI. While the Sky voice and a version of ChatGPT Voice have been around for some time, the comparison to Johansson became more obvious due to OpenAI CEO Sam Altman, and many others, drawing the similarity between the new AI model and the movie "Her". In "Her," Scarlett Johansson voices an advanced AI operating system named Samantha, who develops a romantic relationship with a lonely writer played by Joaquin Phoenix. With its ability to mimic emotional responses, the parallels from GPT-4o were obvious.

A new Pew Research Center analysis shows just how fleeting online content actually is: 1. A quarter of all webpages that existed at one point between 2013 and 2023 are no longer accessible, as of October 2023. In most cases, this is because an individual page was deleted or removed on an otherwise functional website. 2. For older content, this trend is even starker. Some 38% of webpages that existed in 2013 are not available today, compared with 8% of pages that existed in 2023. This "digital decay" occurs in many different online spaces. We examined the links that appear on government and news websites, as well as in the "References" section of Wikipedia pages as of spring 2023. This analysis found that: 1. 23% of news webpages contain at least one broken link, as do 21% of webpages from government sites. News sites with a high level of site traffic and those with less are about equally likely to contain broken links. Local-level government webpages (those belonging to city governments) are especially likely to have broken links. 2. 54% of Wikipedia pages contain at least one link in their "References" section that points to a page that no longer exists.[...]

Julian Assange has won a victory in his ongoing battle against extradition from the UK after judges at the high court in London granted him leave to appeal. From a report: Two judges deferred a decision in March on whether Assange, who is trying to avoid being prosecuted in the US on espionage charges relating to the publication of thousands of classified and diplomatic documents, could take his case to another appeal hearing. Assange had been granted permission to appeal only if the Biden administration was unable to provide the court with suitable assurances "that the applicant [Assange] is permitted to rely on the first amendment, that the applicant is not prejudiced at trial, including sentence, by reason of his nationality, that he is afforded the same first amendment [free speech] protections as a United States citizen, and that the death penalty is not imposed." Legal argument on Monday focused on the issue of whether Assange would be allowed first amendment protections. Assange's team did not contest the assurance around the death penalty, accepting that it was an "unambiguous executive promise." Assange has been indicted on 17 espionage charges and one charge of computer misuse, exposing him to a maximum 175 years in prison, over his website's publication of a trove of classified US documents almost 15 years ago.
