Google Targets Filmmakers With Veo, Its New Generative AI Video Model

Par : BeauHD
15 mai 2024 à 00:50
At its I/O developer conference today, Google announced Veo, its latest generative AI video model, that "can generate 'high-quality' 1080p resolution videos over a minute in length in a wide variety of visual and cinematic styles," reports The Verge. From the report: Veo has "an advanced understanding of natural language," according to Google's press release, enabling the model to understand cinematic terms like "timelapse" or "aerial shots of a landscape." Users can direct their desired output using text, image, or video-based prompts, and Google says the resulting videos are "more consistent and coherent," depicting more realistic movement for people, animals, and objects throughout shots. Google DeepMind CEO Demis Hassabis said in a press preview on Monday that video results can be refined using additional prompts and that Google is exploring additional features to enable Veo to produce storyboards and longer scenes. As is the case with many of these AI model previews, most folks hoping to try Veo out themselves will likely have to wait a while. Google says it's inviting select filmmakers and creators to experiment with the model to determine how it can best support creatives and will build on these collaborations to ensure "creators have a voice" in how Google's AI technologies are developed. Some Veo features will also be made available to "select creators in the coming weeks" in a private preview inside VideoFX -- you can sign up for the waitlist here for an early chance to try it out. Otherwise, Google is also planning to add some of its capabilities to YouTube Shorts "in the future." Along with its new AI models and tools, Google said it's expanding its AI content watermarking and detection technology. The company's new upgraded SynthID watermark imprinting system "can now mark video that was digitally generated, as well as AI-generated text," reports The Verge in a separate report.

An anonymous reader quotes a report from UploadVR: 1 in 4 U.S. teens told Pew Research Center they play games on a VR headset. The survey was conducted on 1453 U.S. teens aged 13 to 17. Pew claims the participants were "recruited primarily through national, random sampling of residential addresses" and "weighted to be representative of U.S. teens ages 13 to 17 who live with their parents by age, gender, race and ethnicity, household income, and other categories." Broken out by gender, 32% of boys and 15% of girls said they play games on a VR headset. The survey doesn't ask whether they actually own the headset, so this will include those who play on a sibling or parent's headset.

14 mai 2024 à 23:30
OpenAI's co-founder and Chief Scientist, Ilya Sutskever, is leaving the company to work on "something personally meaningful," wrote CEO Sam Altman in a post on X. "This is very sad to me; Ilya is easily one of the greatest minds of our generation, a guiding light of our field, and a dear friend. [...] I am forever grateful for what he did here and committed to finishing the mission we started together." He will be replaced by OpenAI researcher Jakub Pachocki. Here's Altman's full X post announcing the departure: Ilya and OpenAI are going to part ways. This is very sad to me; Ilya is easily one of the greatest minds of our generation, a guiding light of our field, and a dear friend. His brilliance and vision are well known; his warmth and compassion are less well known but no less important. OpenAI would not be what it is without him. Although he has something personally meaningful he is going to go work on, I am forever grateful for what he did here and committed to finishing the mission we started together. I am happy that for so long I got to be close to such genuinely remarkable genius, and someone so focused on getting to the best future for humanity. Jakub is going to be our new Chief Scientist. Jakub is also easily one of the greatest minds of our generation; I am thrilled he is taking the baton here. He has run many of our most important projects, and I am very confident he will lead us to make rapid and safe progress towards our mission of ensuring that AGI benefits everyone. The New York Times notes that Ilya joined three other board members to force out Altman in a chaotic weekend last November. Ultimately, Altman returned as CEO five days later. Ilya said he regretted the move.

VMware Giving Away Workstation Pro, Fusion Pro Free For Personal Use

Par : BeauHD
14 mai 2024 à 22:50
Dan Robinson reports via The Register: VMware has made another small but notable post-merger concession to users: the Workstation Pro and Fusion Pro desktop hypervisor products will now be free for personal use. The cloud and virtualization biz, now a Broadcom subsidiary, has announced that its Pro apps will be available under two license models: a "Free Personal Use" or a "Paid Commercial Use" subscription for organizations. Workstation Pro is available for PC users running Windows or Linux, while Fusion Pro is available for Mac systems with either Intel CPUs or Apple's own processors. The two products allow users to create a virtual machine on their local computer for the purpose of running a different operating system or creating a sandbox in which to run certain software. [...] According to VMware, users will get to decide for themselves if their use case calls for a commercial subscription. There are no functional differences between the two versions, the company states, and the only visual difference is that the free version displays the text: "This product is licensed for personal use only." "This means that everyday users who want a virtual lab on their Mac, Windows, or Linux computer can do so for free simply by registering and downloading the bits from the new download portal located at support.broadcom.com," VMware says. Customers that require a paid commercial subscription must purchase through an authorized Broadcom Advantage partner. The move also means that VMware's Workstation Player and Fusion Player products are effectively redundant as the Pro products now serve the same role, and so those will no longer be offered for purchase. Organizations with commercial licenses for Fusion Player 13 or Workstation Player 17 can continue to use these, however, and they will continue to be supported for existing end of life (EOL) and end of general support (EoGS) dates.

Feds Probe Waymo Driverless Cars Hitting Parked Cars, Drifting Into Traffic

Par : BeauHD
14 mai 2024 à 22:10
An anonymous reader quotes a report from Ars Technica: Crashing into parked cars, drifting over into oncoming traffic, intruding into construction zones -- all this "unexpected behavior" from Waymo's self-driving vehicles may be violating traffic laws, the US National Highway Traffic Safety Administration (NHTSA) said (PDF) Monday. To better understand Waymo's potential safety risks, NHTSA's Office of Defects Investigation (ODI) is now looking into 22 incident reports involving cars equipped with Waymo's fifth-generation automated driving system. Seventeen incidents involved collisions, but none involved injuries. Some of the reports came directly from Waymo, while others "were identified based on publicly available reports," NHTSA said. The reports document single-party crashes into "stationary and semi-stationary objects such as gates and chains" as well as instances in which Waymo cars "appeared to disobey traffic safety control devices." The ODI plans to compare notes between incidents to decide if Waymo cars pose a safety risk or require updates to prevent malfunctioning. There is already evidence from the ODI's initial evaluation showing that Waymo's automated driving systems (ADS) were either "engaged throughout the incident" or abruptly "disengaged in the moments just before an incident occurred," NHTSA said. The probe is the first step before NHTSA can issue a potential recall, Reuters reported. A Waymo spokesperson said the company currently serves "over 50,000 weekly trips for our riders in some of the most challenging and complex environments." When a collision occurs, Waymo reviews each case and continually updates the ADS software to enhance performance. "We are proud of our performance and safety record over tens of millions of autonomous miles driven, as well as our demonstrated commitment to safety transparency," Waymo's spokesperson said, confirming that Waymo would "continue to work" with the ODI to enhance ADS safety.

Ordered Back To the Office, Top Tech Talent Left Instead, Study Finds

Par : BeauHD
14 mai 2024 à 13:00
An anonymous reader quotes a report from the Washington Post: Return-to-office mandates at some of the most powerful tech companies -- Apple, Microsoft and SpaceX -- were followed by a spike in departures among the most senior, tough-to-replace talent, according to a case study published last week by researchers at the University of Chicago and the University of Michigan. Researchers drew on resume data from People Data Labs to understand the impact that forced returns to offices had on employee tenure and the movement of workers between companies. What they found was a strong correlation between the departures of senior-level employees and the implementation of a mandate, suggesting that these policies "had a negative effect on the tenure and seniority of their respective workforce." High-ranking employees stayed several months less than they might have without the mandate, the research suggests -- and in many cases, they went to work for direct competitors. At Microsoft, the share of senior employees as a portion of the company's overall workforce declined more than five percentage points after the return-to-office mandate took effect, the researchers found. At Apple, the decline was four percentage points, while at SpaceX -- the only company of the three to require workers to be fully in-person -- the share of senior employees dropped 15 percentage points. "We find experienced employees impacted by these policies at major tech companies seek work elsewhere, taking some of the most valuable human capital investments and tools of productivity with them," said Austin Wright, an assistant professor of public policy at the University of Chicago and one of the study's authors. "Business leaders should weigh carefully employee preferences and market opportunities when deciding when, or if, they mandate a return to office." While the corporate culture and return-to-office policies differ "markedly" between the three companies, the similar effects of the RTO mandates suggest that "the effects are driven by common underlying dynamics," wrote the authors of the study. "Our findings suggest that RTO mandates cost the company more than previously thought," said David Van Dijcke, a researcher at the University of Michigan who worked on the study. "These attrition rates aren't just something that can be managed away." Robert Ployhart, a professor of business administration and management at the University of South Carolina, said executives haven't provided much evidence that RTO mandates actually benefit their workforces. "The people sitting at the apex may not like the way they feel the organization is being run, but if they're not bringing data to that point of view, it's really hard to argue why people should be coming back to the workplace more frequently," Ployhart said. Senior employees, he said, are "the caretakers of a company's culture," and having to replace them can have negative effects on team morale and productivity. "By driving those employees away, they've actually enhanced and sped up the very thing they were trying to stop," Ployhart said.

Internet Use Is Associated With Greater Wellbeing, Global Study Finds

Par : BeauHD
14 mai 2024 à 10:00
According to a new study published in the journal Technology, Mind and Behavior, researchers found that internet use is associated with greater wellbeing in people around the world. "Our analysis is the first to test whether or not internet access, mobile internet access and regular use of the internet relates to wellbeing on a global level," said Prof Andrew Przybylski, of the University of Oxford, who co-authored the work. The Guardian reports: [T]he study describes how Przybylski and Dr Matti Vuorre, of Tilburg University in the Netherlands, analysed data collected through interviews involving about 1,000 people each year from 168 countries as part of the Gallup World Poll. Participants were asked about their internet access and use as well as eight different measures of wellbeing, such as life satisfaction, social life, purpose in life and feelings of community wellbeing. The team analyzed data from 2006 to 2021, encompassing about 2.4 million participants aged 15 and above. The researchers employed more than 33,000 statistical models, allowing them to explore various possible associations while taking into account factors that could influence them, such as income, education, health problems and relationship status. The results reveal that internet access, mobile internet access and use generally predicted higher measures of the different aspects of wellbeing, with 84.9% of associations between internet connectivity and wellbeing positive, 0.4% negative and 14.7% not statistically significant. The study was not able to prove cause and effect, but the team found measures of life satisfaction were 8.5% higher for those who had internet access. Nor did the study look at the length of time people spent using the internet or what they used it for, while some factors that could explain associations may not have be considered. Przybylski said it was important that policy on technology was evidence-based and that the impact of any interventions was tracked.

Cruise Is Back Driving Autonomously After Pedestrian-Dragging Incident

Par : BeauHD
14 mai 2024 à 07:00
Cruise's autonomous vehicles have resumed operation in Phoenix, Arizona, following an incident in San Francisco last October where a driverless vehicle dragged a pedestrian. The Verge reports: Cruise spokesperson Tiffany Testo said the company is deploying only two autonomous vehicles with safety drivers behind the wheel. In addition, the company has eight manually driven vehicles in the city. Eventually, the service area will "gradually expand" to include Scottsdale, Paradise Valley, Tempe, Mesa, Gilbert, and Chandler -- "measured against predetermined safety benchmarks." Cruise's slow return to the road is noteworthy, given the huge hurdles facing the company in the wake of the October incident. Regulators accused the company of misleading them about the nature and severity of the incident, in which a pedestrian was dragged over 20 feet by a driverless Cruise after first being struck by a hit-and-run driver. Several top executives have since left the company, including founder and CEO Kyle Vogt, and around a quarter of employees were laid off. GM has said it will reduce its spending on Cruise. And an outside report found evidence that a culture of antagonism toward regulators contributed to many of the failings.

Slashdot Asks: How Do You Protest AI Development?

Par : BeauHD
14 mai 2024 à 03:30
An anonymous reader quotes a report from Wired: On a side street outside the headquarters of the Department of Science, Innovation and Technology in the center of London on Monday, 20 or so protesters are getting their chants in order. "What do we want? Safe AI! When do we want it?" The protesters hesitate. "Later?" someone offers. The group of mostly young men huddle for a moment before breaking into a new chant. "What do we want? Pause AI! When do we want it? Now!" These protesters are part of Pause AI, a group of activists petitioning for companies to pause development of large AI models which they fear could pose a risk to the future of humanity. Other PauseAI protests are taking place across the globe: In San Francisco, New York, Berlin, Rome, Ottawa, and ahandful of other cities. Their aim is to grab the attention of voters and politicians ahead of the AI Seoul Summit -- a follow-up to the AI Safety Summit held in the UK in November 2023. But the loosely organized group of protesters itself is still figuring out exactly the best way to communicate its message. "The Summit didn't actually lead to meaningful regulations," says Joep Meindertsma, the founder of PauseAI. The attendees at the conference agreed to the "Bletchley Declaration," but that agreement doesn't mean much, Meindertsma says. "It's only a small first step, and what we need are binding international treaties." [...] There is also the question of how PauseAI should achieve its aims. On the group's Discord, some members discussed the idea of staging sit-ins at the headquarters of AI developers. OpenAI, in particular, has become a focal point of AI protests. In February, Pause AI protests gathered in front of OpenAI'sSan Francisco offices, after the company changed its usage policies to remove a ban on military and warfare applications for its products. Would it be too disruptive if protests staged sit-ins or chained themselves to the doors of AI developers, one member of the Discord asked. "Probably not. We do what we have to, in the end, for a future with humanity, while we still can." [...] Director of Pause AI US, Holly Elmore, wants the movement to be a "broad church" that includes artists, writers, and copyright owners whose livelihoods are put at risk from AI systems that can mimic creative works. "I'm a utilitarian. I'm thinking about the consequences ultimately, but the injustice that really drives me to do this kind of activism is the lack of consent" from companies producing AI models, she says. "We don't have to choose which AI harm is the most important when we're talking about pausing as a solution. Pause is the only solution that addresses all of them." [Joseph Miller, the organizer of PauseAI's protest in London] echoed this point. He says he's spoken to artists whose livelihoods have been impacted by the growth of AI art generators. "These are problems that are real today, and are signs of much more dangerous things to come." One of the London protesters, Gideon Futerman, has a stack of leaflets he's attempting to hand out to civil servants leaving the building opposite. He has been protesting with the group since last year. "The idea of a pause being possible has really taken root since then," he says. According to Wired, the leaders of Pause AI said they were not considering sit-ins or encampments near AI offices at this time. "Our tactics and our methods are actually very moderate," says Elmore. "I want to be the moderate base for a lot of organizations in this space. I'm sure we would never condone violence. I also want Pause AI to go further than that and just be very trustworthy." Meindertsma agrees, saying that more disruptive action isn't justified at the moment. "I truly hope that we don't need to take other actions. I don't expect that we'll need to. I don't feel like I'm the type of person to lead a movement that isn't completely legal." Slashdotters, what is the most effective way to protest AI development? Is the AI genie out of the bottle?

Intel Aurora Supercomputer Breaks Exascale Barrier

Par : BeauHD
14 mai 2024 à 02:02
Josh Norem reports via ExtremeTech: At the recent International supercomputing conference called ISC 2024, Intel's newest Aurora supercomputer installed at Argonne National Laboratory raised a few eyebrows by finally surpassing the exascale barrier. Before this, only AMD's Frontier system had been able to achieve this level of performance. Intel also achieved what it says is the world's best performance for AI at 10.61 "AI exaflops." Intel reported the news on its blog, stating Aurora was now officially the fastest supercomputer for AI in the world. It shares the distinction in collaboration with Argonne National Laboratory and Hewlett Packard Enterprise (HPE), which both built and houses the system in its current state, which Intel says was at 87% functionality for the recent tests. In the all-important Linpack (HPL) test, the Aurora computer hit 1.012 exaflops, meaning it has almost doubled the performance on tap since its initial "partial run" in late 2023, where it hit just 585.34 petaflops. The company then said it expected to cross the exascale barrier with Aurora eventually, and now it has. Intel says for the ISC 2024 tests, Aurora was operating with 9,234 nodes. The company notes it ranked second overall in LINPACK, meaning it's still unable to dethrone AMD's Frontier system, which is also an HPE supercomputer. AMD's Frontier was the first supercomputer to break the exascale barrier in June 2022. Frontier sits at around 1.2 exaflops in Linpack, so Intel is knocking on its door but still has a way to go before it can topple it. However, Intel says Aurora came in first in the Linpack-mixed benchmark, reportedly highlighting its unparalleled AI performance. Intel's Aurora supercomputer uses the company's latest CPU and GPU hardware, with 21,248 Sapphire Rapids Xeon CPUs and 63,744 Ponte Vecchio GPUs. When it's fully operational later this year, Intel believes the system will eventually be capable of crossing the 2-exaflop barrier.

Biden Admin Shells Out $120 Million To Return Chip Startup To US Ownership

Par : BeauHD
14 mai 2024 à 00:47
Brandon Vigliarolo reports via The Register: Not everything in the semiconductor industry is about shearing off every last nanometer, which is why the Biden administration is splashing out CHIPS Act funding to those pursuing less cutting edge processor production. Case in point, today's announcement that Bloomington, Minnesota-based Polar Semiconductor could be getting up to $120 million in CHIPS funds to double production capacity over the next two years, along with a possible buyout to return the business to U.S. hands. Polar, which manufactures semiconductors used primarily for the energy industry and electric vehicles, will use the funds to double its production capacity of sensor and power chips and upgrade its manufacturing kit, as well as adding 160 jobs to boot. Along with expanding production, the U.S. Department of Commerce said the funding would trigger additional private capital investment to "transform Polar from a majority foreign-owned in-house manufacturer to a majority U.S.-owned commercial foundry, expanding opportunities for U.S. chip designers to innovate and produce technologies domestically." In other words - sure it'll expand the output, but the real win is another majority U.S.-owned foundry for the White House to tout. According to its website, Polar is currently owned by Korean conglomerate SK Group and serves as the primary fab and engineering center for Japanese firm Sanken Electric. Not exactly companies in countries with poor U.S. relations - but overseas owners, nonetheless. "This proposed investment in Polar will crowd in private capital, which will help make Polar a U.S.-based, independent foundry," said U.S. Commerce secretary Gina Raimondo. "They will be able to expand their customer base and create a stable domestic supply of critical chips, made in America's heartland."

IBM Open-Sources Its Granite AI Models

Par : BeauHD
14 mai 2024 à 00:02
An anonymous reader quotes a report from ZDNet: IBM managed the open sourcing of Granite code by using pretraining data from publicly available datasets, such as GitHub Code Clean, Starcoder data, public code repositories, and GitHub issues. In short, IBM has gone to great lengths to avoid copyright or legal issues. The Granite Code Base models are trained on 3- to 4-terabyte tokens of code data and natural language code-related datasets. All these models are licensed under the Apache 2.0 license for research and commercial use. It's that last word -- commercial -- that stopped the other major LLMs from being open-sourced. No one else wanted to share their LLM goodies. But, as IBM Research chief scientist Ruchir Puri said, "We are transforming the generative AI landscape for software by releasing the highest performing, cost-efficient code LLMs, empowering the open community to innovate without restrictions." Without restrictions, perhaps, but not without specific applications in mind. The Granite models, as IBM ecosystem general manager Kate Woolley said last year, are not "about trying to be everything to everybody. This is not about writing poems about your dog. This is about curated models that can be tuned and are very targeted for the business use cases we want the enterprise to use. Specifically, they're for programming." These decoder-only models, trained on code from 116 programming languages, range from 3 to 34 billion parameters. They support many developer uses, from complex application modernization to on-device memory-constrained tasks. IBM has already used these LLMs internally in IBM Watsonx Code Assistant (WCA) products, such as WCA for Ansible Lightspeed for IT Automation and WCA for IBM Z for modernizing COBOL applications. Not everyone can afford Watsonx, but now, anyone can work with the Granite LLMs using IBM and Red Hat's InstructLab.

Melinda French Gates announced today she is stepping down from the Bill and Melinda Gates Foundation, three years after announcing her separation from Microsoft co-founder Bill Gates. With her departure as co-chair, the foundation will change its name to Gates Foundation and Bill Gates will be its sole chairperson, said CEO Mark Suzman. NBC News reports: In a statement posted on her Instagram account, she said that as part of her agreement to step down from the foundation, she will retain $12.5 billion that she plans to put toward her ongoing work supporting women and families. "This is not a decision I came to lightly," French Gates wrote. "I am immensely proud of the foundation that Bill and I built together and of the extraordinary work it is doing to address inequities around the world." In a separate statement, Bill Gates said, "I am sorry to see Melinda leave, but I am sure she will have a huge impact in her future philanthropic work." Now worth $75.2 billion, the Gates Foundation has over the course of its three-decade lifespan made $77.6 billion worth of grant payments, making it one of the largest donor organizations in the world, with a focus on health and developmental goals. It is one of the largest contributors to the World Health Organization, and played a key role in efforts to address the Covid pandemic. "After a difficult few years watching women's rights rolled back in the U.S. and around the world, she wants to use this next chapter to focus specifically on altering that trajectory," Suzman said of French Gates. "I want to reassure you that the millions of people our work serves and the thousands of partners we work alongside can continue to count on the foundation. The foundation today is stronger than it has ever been." "I know we all wish Melinda the best in her next chapter," he added, noting that French Gates "will not be bringing any of the foundation's work with her when she leaves."

'Roaring Kitty' Trader Returns, Causing GameStop Shares To Jump More Than 70%

Par : BeauHD
13 mai 2024 à 21:20
GameStop shares surged over 72% on Monday after Keith Gill, also known as "Roaring Kitty," returned to social media following a three-year hiatus. Gill gained notoriety for his role in the 2020 meme stock frenzy, where he encouraged amateur investors to buy GameStop shares, significantly driving up the stock price and challenging hedge funds. From a report: He resurfaced on X, Sunday night, with an image of a sketched man leaning forward in a chair, marking the end of a roughly three-year hiatus. He followed that post with several others featuring various comeback-themed videos featuring movie clips and charged music. GameStop had experienced declining sales amid an industrywide pivot from game cartridges to video game streaming and digital downloads, but with the help from meme stock investors, last March the company turned its first profit in two years. Before then, the company had posted seven straight quarterly losses. This January, GameStop reported its first annual profit since 2018. Roaring Kitty's post helped bump GameStop's share price to $28.25 on Monday. GameStop's all-time high stock price is $120.75 in January 2021.

First Person To Receive a Genetically Modified Pig Kidney Transplant Dies

13 mai 2024 à 20:40
An anonymous reader quotes a report from CBS News: Richard "Rick" Slayman, the first human to receive a genetically modified pig kidney transplant, has died almost two months after the procedure. Slayman, who had end-stage kidney disease, underwent the transplant in March at Massachusetts General Hospital in Boston at age 62. The hospital said in a statement on Saturday that there was "no indication" that his death was the result of the transplant. The transplant surgeon had said he hoped the transplant would function for at least two years. "The Mass General transplant team is deeply saddened at the sudden passing of Mr. Rick Slayman," read the hospital statement. "Mr. Slayman will forever be seen as a beacon of hope to countless transplant patients worldwide and we are deeply grateful for his trust and willingness to advance the field of xenotransplantation." The surgery was a milestone for the field of xenotransplantation -- the transplant of organs from one species to another -- as a way to alleviate the organ shortage for people who need transplants. The effort to genetically modify animal organs is in hopes that the human body will not reject the foreign tissue. NPR notes that there are more than 100,000 people in the U.S. on the waitlist for organs.

Bike Brands Start To Adopt C-V2X To Warn Cyclists About Cars

Par : BeauHD
11 mai 2024 à 13:00
An anonymous reader quotes a report from Ars Technica: There's a fundamental flaw in current car safety tech: It's limited to line of sight. Or, perhaps, line of "sensing" is more accurate, because the way cameras and lidar work is to inspect the perimeter of a vehicle and use predictive algorithms to understand the motion of an object in relation to the motion of the vehicle itself. Which is good, because as carmakers have added elements such as pedestrian and cyclist detection, they're trying to prevent drivers from hurting the most vulnerable road users. And unfortunately this is necessary, because even though 2023 saw a slight reduction in drivers striking cyclists and pedestrians, according to the most recent data from the Governor's Highway Safety Association, since 2019 pedestrian fatalities are still up 14 percent -- and cyclist deaths are up 50 percent since 2010. That doesn't mean lidar and cameras have "failed," but because they rely on what the sensors can pick up, they cannot necessarily ID hazards (and alert drivers) as quickly as we need them to, particularly if that's a cyclist in your lane 300 feet down the road, just over the next rise. Yes, current sensing works well now with figuring out the pace of a traffic jam, and automatic emergency braking can step in to stop your car if you fail to. But for non-automotive obstacles, they're still limited. For that, we need better tech, which is emerging and is called Connected Vehicle to Everything (C-V2X). The idea isn't that complicated. Boiled down, it's a chipset that operates on a portion of the cellular bandwidth, and vehicles with this tech embedded (say in an e-bike or car) monitor anything with a C-V2X chip as well as broadcast their own location at a pulse of 10 times a second. This precision location system would then warn a driver of a cyclist on the road ahead, even beyond line of sight, and in an emergency -- possibly because a cyclist was right in a car's path -- could prevent a collision. [W]ith C-V2X, you don't need Verizon or ATT or anything like that," explains Audi's Kamal Kapadia. Because it isn't using the cellular network -- it's using a portion of cellular bandwidth to allow direct object, or vehicle-to-vehicle, communication. Audi has been working on C-V2X for nearly a decade, and it's part of a group in the US called the Coalition for Cyclist Safety, which also includes suppliers like Bosch, a tech startup in the space called Spoke Safety, and bike brands such as massive Trek, parts supplier Shimano, more niche bikemakers like Switzerland's Stromer, as well as mega telco suppliers and networks such as Qualcomm, Deutsche Telekom, and TELUS. [...] Mio Suzuki is Trek Bicycle's director of embedded systems, "and we are exploring all sorts of safety," she says. For instance, Trek recently introduced its own radar tail light, which warns riders of a car approaching rapidly -- Garmin has had similar systems for several years. But Suzuki is intrigued by C-V2X because it offers more advanced warning than rear-facing radar. "And unlike cars, we have a very vulnerable road user so we need to augment our senses and the rider's awareness of the riding environment, because we don't have a big metal shield around us." What Suzuki envisions this direct communication might enable is an e-bike where the rider has a display that would warn a rider "of an imminent danger that's approaching; a car might be coming from the side, but the view of the car is obstructed by a building, so the rider can't see." Franz Reindl is CTO of Stromer, a high-end Swiss brand that only makes e-bikes with very top tech, including ABS brakes. Reindl says they're also studying C-V2X. "Safety is one of our biggest promises, and we need to do everything we can with products and technologies to make it more safe for customers." Right now, only Audi and the VW Group have openly talked about using the tech. "Trek's Suzuki thinks that together, the Coalition and so many bike brands within it do have a strong voice," reports Ars. "She also envisions municipalities deploying the technology, especially around work crews and EMS, which should build broader momentum and pressure on automakers."

The Russia-linked ransomware group Black Basta is responsible for Wednesday's cyberattack on St. Louis-based Ascension health system, according to sources reported by CNN. The attack disrupted access to electronic health records, some phone systems and "various systems utilized to order certain tests, procedures and medications," the company said in a statement. From a report: On Friday, the nonprofit group Health-ISAC (Information Sharing and Analysis Center) issued an alert about the group, saying that Black Basta has "recently accelerated attacks against the healthcare sector." HHS said that Black Basta was initially spotted in early 2022, known for its double extortion attack. The group not only executes ransomware but also exfiltrates sensitive data, operating a cybercrime marketplace to publicly release it should a victim fail to pay a ransom. "The level of sophistication by its proficient ransomware operators, and reluctance to recruit or advertise on Dark Web forums, supports why many suspect the nascent Black Basta may even be a rebrand of the Russian-speaking RaaS threat group Conti, or also linked to other Russian-speaking cyber threat groups," the alert from HHS said. According to one report from blockchain analytics firm Elliptic and cybersecurity risk-focused Corvus Insurance, Black Basta in less than two years has won itself more than $100 million via ransomware schemes from 329 organizations. Previous victims of its attacks include Dish Network, the American Dental Association, business process services firm Capita and tech firm ABB.

'Tungsten Wall' Leads To Nuclear Fusion Breakthrough

A tokamak in France achieved a new record in fusion plasma by using tungsten to encase its reaction, which enabled the sustainment of hotter and denser plasma for longer periods than previous carbon-based designs. Quartz reports: A tokamak is a torus- (doughnut-) shaped fusion device that confines plasma using magnetic fields, allowing scientists to fiddle with the superheated material and induce fusion reactions. The recent achievement was made in WEST (tungsten (W) Environment in Steady-state Tokamak), a tokamak operated by the French Alternative Energies and Atomic Energy Commission (CEA). WEST was injected with 1.15 gigajoules of power and sustained a plasma of about 50 million degrees Celsius for six minutes. It achieved this record after scientists encased the tokamak's interior in tungsten, a metal with an extraordinarily high melting point. Researchers from Princeton Plasma Physics Laboratory used an X-ray detector inside the tokamak to measure aspects of the plasma and the conditions that made it possible. "These are beautiful results," said Xavier Litaudon, a scientist with CEA and chair of the Coordination on International Challenges on Long duration OPeration (CICLOP), in a PPPL release. "We have reached a stationary regime despite being in a challenging environment due to this tungsten wall."
