Apollo To Provide $11 Billion To Intel For Ireland Facility

Par : BeauHD
4 juin 2024 à 22:02
Apollo Global announced today that it will acquire a 49% equity interest in Intel's manufacturing facility in Ireland for $11 billion, in a deal expected to close in the second quarter. The deal "would allow Intel to redeploy parts of its investment in the project to other parts of its business," reports Reuters. "Intel has invested $18.4 billion in the facility till date." From the report: Apollo will acquire the stake in the Fab 34 facility in Leixlip, Ireland, the U.S. chipmaker's first high-volume location for its Intel 4 manufacturing process using extreme ultraviolet lithography machines. The company announced plans in 2022 to build chip factories in Ireland and France as it seeks to benefit from easier European Commission funding rules and subsidies as the bloc looks to cut its dependence on U.S. and Asian supply. Intel will retain full ownership and operational control of Fab 34 and its assets.

Online Streaming Services In Canada Must Hand Over 5% of Domestic Revenues

An anonymous reader quotes a report from CBC News: Online streaming services operating in Canada will be required to contribute five percent of their Canadian revenues to support the domestic broadcasting system, the country's telecoms regulator said on Tuesday. The money will be used to boost funding for local and Indigenous broadcasting, officials from the Canadian Radio-television and Telecommunications Commission (CRTC) said in a briefing. "Today's decision will help ensure that online streaming services make meaningful contributions to Canadian and Indigenous content," wrote CRTC chief executive and chair Vicky Eatrides in a statement. The measure was introduced under the auspices of a law passed last year designed to make sure that companies like Netflix make a more significant contribution to Canadian culture. The government says the legislation will ensure that online streaming services promote Canadian music and stories, and support Canadian jobs. Funding will also be directed to French-language content and content created by official language minority communities, as well as content created by equity-deserving groups and Canadians of diverse backgrounds. The release also said that online streaming services will "have some flexibility" to send their revenues to support Canadian television directly. [...] The measure, which will start in the 2024-2025 broadcasting year, would raise roughly $200 million annually, CRTC officials said. It will only apply to services that are not already affiliated with Canadian broadcasters. The CMPA was among 20 screen organizations from around the world that signed a statement in January asking governments to impose stronger regulations on streaming companies operating in local markets. One of the demands was a measure that would force companies profiting from their presence in those markets to contribute financially to the creation of new local content."We are disappointed by today's decision and concerned by the negative impact it will have on Canadian consumers. We are assessing the decision in full, but this onerous and inflexible financial levy will be harmful to consumer choice," a spokesperson for Prime Video wrote to CBC News in a statement.

ChatGPT, Claude and Perplexity All Went Down At the Same Time

Sarah Perez reports via TechCrunch: After a multi-hour outage that took place in the early hours of the morning, OpenAI's ChatGPT chatbot went down again -- but this time, it wasn't the only AI provider affected. On Tuesday morning, both Anthropic's Claude and Perplexity began seeing issues, too, but these were more quickly resolved. Google's Gemini appears to be operating at present, though it may have also briefly gone offline, according to some user reports. It's unusual for three major AI providers to all be down at the same time, which could signal a broader infrastructure issue or internet-scale problem, such as those that affect multiple social media sites simultaneously, for example. It's also possible that Claude and Perplexity's issues were not due to bugs or other issues, but from receiving too much traffic in a short period of time due to ChatGPT's outage.

An anonymous reader quotes a report from PCMag: Justin Long, the actor known for playing the Mac guy in Apple's mid-2000s ad campaign is once again switching sides -- this time to promote new Windows laptops from Qualcomm. Long appeared in a video that Qualcomm showed during its Computex keynote. To introduce the segment, CEO Cristiano Amon said Qualcomm captured video of a "very special person" preordering a Windows Copilot+ laptop built with a Snapdragon X Elite chip. In the clip, we see Long typing on an Apple MacBook at home and getting annoyed by all the incoming notifications, which include warnings that his laptop only has a 1% battery life and is running out of disk space. Long types in a search for "Where can I find a Snapdragon-powered PC?" and then stares at the camera, looking a bit ashamed, before saying: "What? Things change." Amon then returned to the stage to tell the Computex audience: "Yes, things change." In 2021, Long starred in an Intel ad campaign to promote the company's Windows PCs.

The PlayStation VR2's PC adapter is arriving on August 7th, allowing PC support for the PS5-exclusive headset. It'll cost $59.99. The Verge reports: Sony says the device will support all Steam VR games, including big-name titles like Half-Life: Alyx. In addition to the new adapter, Sony says players will need a DisplayPort cable to work with Steam titles on PC. (As well as a Steam account, obviously.) You can check out the minimum system requirements right here. In a blog post, Sony explains that there will be some feature differences depending on whether you're playing on PS5 or PC: "PS VR2 was designed from the ground up specifically for PS5 -- so you'll notice that some key features, like HDR, headset feedback, eye tracking, adaptive triggers, and haptic feedback (other than rumble), are not available when playing on PC. However, other high-fidelity and sensory immersion features of PS VR2 are supported, including 4K visuals (2000 x 2040 per eye), 110-degree field of view, finger touch detection, and see-through view, as well as foveated rendering (without eye tracking) and 3D Audio in supported games."

Woman Who Received Pig Kidney Transplant Has It Removed

Par : BeauHD
4 juin 2024 à 07:00
Due to complications with a mechanical heart pump, surgeons in New York removed a pig kidney from Lisa Pisano less than two months after transplanting it. The genetically engineered pig kidney did not show signs of rejection but suffered from inadequate blood flow. Wired reports: Pisano was facing heart and kidney failure and required routine dialysis. She wasn't eligible to receive a traditional heart and kidney transplant from a human donor because of several chronic medical conditions that reduced the likelihood of a good outcome. Pisano first received a heart pump at NYU Langone Health on April 4, followed by the pig kidney transplant on April 12. The heart pump, a device called a left ventricular assist device or LVAD, is used in patients who are either awaiting heart transplantation or otherwise aren't a candidate for a heart transplant. In a statement provided to WIRED, Pisano's medical team explained that they electively removed the pig kidney on May 29-47 days after transplant -- after several episodes of the heart pump not being able to pass enough blood through the transplanted kidney. Steady blood flow is important so that the kidney can produce urine and filter waste. Without it, Pisano's kidney function began to decline. "On balance, the kidney was no longer contributing enough to justify continuing the immunosuppression regimen," said Robert Montgomery, director of the NYU Langone Transplant Institute, in the statement. Like traditional transplant patients, Pisano needed to take immunosuppressive drugs to prevent her immune system from rejecting the donor organ. The kidney came from a pig genetically engineered by Virginia biotech company Revivicor to lack a gene responsible for the production of a sugar known as alpha-gal. In previous studies at NYU Langone, researchers found that removing this sugar prevented immediate rejection of the organ when transplanted into brain-dead patients. During Pisano's surgery, the donor pig's thymus gland, which is responsible for "educating" the immune system, was also transplanted to reduce the likelihood of rejection. A recent biopsy did not show signs of rejection, but Pisano's kidney was injured due to a lack of blood flow, according to the statement. The team plans to study the explanted pig kidney to learn more.

Crooks Threaten To Leak 3 Billion Personal Records 'Stolen From Background Firm'

An anonymous reader quotes a report from The Register: Billions of records detailing people's personal information may soon be dumped online after being allegedly obtained from a Florida firm that handles background checks and other requests for folks' private info. A criminal gang that goes by the handle USDoD put the database up for sale for $3.5 million on an underworld forum in April, and rather incredibly claimed the trove included 2.9 billion records on all US, Canadian, and British citizens. It's believed one or more miscreants using the handle SXUL was responsible for the alleged exfiltration, who passed it onto USDoD, which is acting as a broker. The pilfered information is said to include individuals' full names, addresses, and address history going back at least three decades, social security numbers, and people's parents, siblings, and relatives, some of whom have been dead for nearly 20 years. According to USDoD, this info was not scraped from public sources, though there may be duplicate entries for people in the database. Fast forward to this month, and the infosec watchers at VX-Underground say they've not only been able to view the database and verify that at least some of its contents are real and accurate, but that USDoD plans to leak the trove. Judging by VX-Underground's assessment, the 277.1GB file contains nearly three billion records on people who've at least lived in the United States -- so US citizens as well as, say, Canadians and Brits. This info was allegedly stolen or otherwise obtained from National Public Data, a small information broker based in Coral Springs that offers API lookups to other companies for things like background checks. There is a small silver lining, according to the VX team: "The database DOES NOT contain information from individuals who use data opt-out services. Every person who used some sort of data opt-out service was not present." So, we guess this is a good lesson in opting out.

AMD Blows Up Its Laptop CPU Numbering System

Par : BeauHD
3 juin 2024 à 23:40
AMD is reverting to a simpler, more traditional numbering scheme for its laptop processors, abandoning its recent complex "decoder ring" system. The new system for Ryzen AI laptop processors will use a three-digit model number to denote generation and SKU, aligning more closely with industry norms. Ars Technica reports: For its new Ryzen AI laptop processors, codenamed "Strix Point," AMD is still using the same broad Ryzen 3/5/7/9 number to communicate general performance level plus a one- or two-letter suffix to denote general performance and power level (U for ultraportables, HX for higher-performance chips, and so on). A new three-digit processor number will inform buyers of the chip's generation in the first digit and denote the specific SKU using the last two digits. In other words, the company is essentially hitting the undo button. Like Intel, AMD is shifting from four-digit numbers to three digits. The Strix Point processor numbers will start with the 300 series, which AMD says is because this is the third generation of Ryzen laptop processors with a neural processing unit (NPU) included. Current 7040-series and 8040-series processors with NPUs are not being renamed retroactively, and AMD plans to stop using the 7000- and 8000-series numbering for processor introductions going forward. AMD wouldn't describe exactly how it would approach CPU model numbers for new products that used older architectures but did say that new processors that didn't meet the 40+ TOPS requirement for Microsoft's Copilot+ program would simply use the "Ryzen" name instead of the new "Ryzen AI" branding. That would include older architectures with slower NPUs, like the current 7040 and 8040-series chips. Desktop CPUs are, once again, totally unaffected by this change. Desktop processors' four-digit model numbers and alphabetic suffixes generally tell you all you need to know about their underlying architecture; the new Ryzen 9000 desktop CPUs and the Zen 5 architecture were also announced today. It seems like a lot of work to do to end up basically where we started, especially when the people at AMD who make and market the desktop chips have been getting by just fine with older model numbers for newly released products when appropriate. But to be fair to AMD, there just isn't a great way to do processor model numbers in a simple and consistent way, at least not given current market realities [...].

Lawmakers in New York have reached a tentative agreement to "prohibit social-media companies from using algorithms to steer content to children without parental consent (source paywalled; alternative source)," according to the Wall Street Journal. "The legislation is aimed at preventing social-media companies from serving automated feeds to minors. The bill, which is still being completed but expected to be voted on this week, also would prohibit platforms from sending minors notifications during overnight hours without parental consent." Meanwhile, the results of New York's first mental health report were released today, finding that depression and anxiety are rampant among NYC's teenagers, "with nearly half of them experiencing symptoms from one of both in recent years," reports NBC New York. "In a recent survey conducted last year, 48% of teenagers reported feeling depressive symptoms ranging from mild to severe. The vast majority, however, reported feeling high levels of resilience. Frequent coping mechanisms include listening to music and using social media."

Adobe Scolded For Selling 'Ansel Adams-Style' Images Generated By AI

Par : BeauHD
3 juin 2024 à 22:20
The Ansel Adams estate said it was "officially on our last nerve" after Adobe was caught selling AI-generated images imitating the late photographer's work. The Verge reports: While Adobe permits AI-generated images to be hosted and sold on its stock image platform, users are required to hold the appropriate rights or ownership over the content they upload. Adobe Stock's Contributor Terms specifically prohibits content "created using prompts containing other artist names, or created using prompts otherwise intended to copy another artist." Adobe responded to the callout, saying it had removed the offending content and had privately messaged the Adams estate to get in touch directly in the future. The Adams estate, however, said it had contacted Adobe directly multiple times since August 2023. "Assuming you want to be taken seriously re: your purported commitment to ethical, responsible AI, while demonstrating respect for the creative community, we invite you to become proactive about complaints like ours, & to stop putting the onus on individual artists/artists' estates to continuously police our IP on your platform, on your terms," said the Adams estate on Threads. "It's past time to stop wasting resources that don't belong to you." Adobe Stock Vice President Matthew Smith previously told The Verge that the company generally moderates all "crowdsourced" Adobe Stock assets before they are made available to customers, employing a "variety" of methods that include "an experienced team of moderators who review submissions." As of January 2024, Smith said the strongest action the company can take to enforce its platform rules is to block Adobe Stock users who violate them. Bassil Elkadi, Adobe's Director of Communications and Public Relations, told The Verge that Adobe is "actively in touch with Ansel Adams on this matter," and that "appropriate steps were taken given the user violated Stock terms." The Adams estate has since thanked Adobe for removing the images, and said that it expects "it will stick this time." "We don't have a problem with anyone taking inspiration from Ansel's photography," said the Adams estate. "But we strenuously object to the unauthorized use of his name to sell products of any kind, including digital products, and this includes AI-generated output -- regardless of whether his name has been used on the input side, or whether a given model has been trained on his work."

Google Can Keep Your Phone If You Send It In For Repair With Non-OEM Parts

3 juin 2024 à 21:40
An anonymous reader quotes a report from Android Authority: Like many other phone makers, Google has a self-repair program for servicing your damaged or malfunctioning Pixel device. As its support site explains, there are options to get repair tools, manuals, and certified parts so you can fix up your Pixel like new. Owners can also choose to simply send their device in to have it repaired professionally. As replacement parts can be expensive, some DIYers choose to use parts from third-party suppliers. But if you go down this route, you may want to avoid sending your device to Google if there's a problem you don't have the skills to fix on your own. As YouTuber Louis Rossmann discovered, Google's service and repair terms and conditions contain a concerning stipulation. The document states that Google will keep your device if a non-OEM part is found. Apparently, this rule has been in effect since July 19, 2023, as marked on the page. Last week, iFixit said they are parting ways with Samsung because the company "does not seem interested in enabling repair at scale." A separate report from 404 Media found that Samsung requires independent repair shops to give them the name, contact information, phone identifier, and customer complaint details of everyone who gets their phone repaired at these shops. "Stunningly, it also requires these nominally independent shops to 'immediately disassemble' any phones that customers have brought them that have been previously repaired with aftermarket or third-party parts and to 'immediately notify' Samsung that the customer has used third-party parts," reports 404 Media.

Napster Sparked a File-Sharing Revolution 25 Years Ago

Par : BeauHD
3 juin 2024 à 21:00
TorrentFreak's Ernesto Van der Sar recalls the rise and fall of Napster, the file-sharing empire that kickstarted a global piracy frenzy 25 years ago. Here's an excerpt from his report: At the end of the nineties, technology and the Internet were a playground for young engineers and 'hackers'. Some of them regularly gathered in the w00w00 IRC chatroom on the EFnet network. This tech-think-tank had many notable members, including WhatsApp founder Jan Koum and Shawn Fanning, who logged on with the nickname Napster. In 1998, 17-year-old Fanning shared an idea with the group. 'Napster' wanted to create a network of computers that could share files with each other. More specifically, a central music database that everyone in the world could access. This idea never left the mind of the young developer. Fanning stopped going to school and flanked by his friend Sean Parker, devoted the following months to making his vision a reality. That moment came on June 1, 1999, when the first public release of Napster was released online. Soon after, the software went viral. Napster was quickly embraced by millions of users, who saw the software as something magical. It was a gateway for musical exploration, one that dwarfed even the largest record stores in town. And all for free. It sounds mundane today, but some equated it to pure technological sorcery. For many top players in the music industry, Napster's sorcery was pure witchcraft. At the time, manufacturing CDs with high profit margins felt like printing money and Napster's appearance threatened to ruin the party. [...] At the start of 2001, Napster's user base reached a peak of more than 26.4 million worldwide. Yet, despite huge growth and backing from investors, the small file-sharing empire couldn't overcome the legal challenges. The RIAA lawsuit resulted in an injunction from the Ninth Circuit Court, which ordered the network to shut down. This happened during July 2001, little more than two years after Napster launched. By September that year, the case had been settled for millions of dollars. While the Napster craze was over, file-sharing had mesmerized the masses and the genie was out of the bottle. Grokster, KaZaa, Morpheus, LimeWire, and many others popped up and provided sharing alternatives, for as long as they lasted. Meanwhile, BitTorrent was also knocking on the door. "Napster paved the way for Apple's iTunes store, to serve the demand that was clearly there," notes Ernesto. "This music streaming landscape was largely pioneered by a Napster 'fan' from Sweden, Daniel Ek." "Like many others, Ek was fascinated by the 'all you can play' experience offered by file-sharing software, and that planted the seeds for the music streaming startup Spotify, where he still serves as CEO today. In fact, Spotify itself used file-sharing technology under the hood to ensure swift playback."

Toyota Apologizes For Cheating On Vehicle Testing, Halts Production of 3 Models

Par : BeauHD
3 juin 2024 à 19:40
An anonymous reader quotes a report from the Associated Press: Toyota Chairman Akio Toyoda apologized Monday for massive cheating on certification tests for seven vehicle models as the automaker suspended production of three of them. The wide-ranging fraudulent testing at Japan's top automaker involved the use of inadequate or outdated data in collision tests, and incorrect testing of airbag inflation and rear-seat damage in crashes. Engine power tests were also found to have been falsified. Toyota Motor Corp., based in Toyota city, central Japan, suspended production in the country of the Corolla Fielder, Corolla Axio and Yaris Cross. The deceptive tests were also found on discontinued models. The company said the wrongdoing does not affect the safety of the vehicles already on roads, which include the Corolla subcompact and Lexus luxury vehicles. "We sincerely apologize," Toyoda told reporters, bowing deeply and holding the position for several seconds, as is customary in Japan at news conferences where companies apologize for misbehavior. A Japanese government investigation into Toyota began in January. The issue does not affect Toyota's overseas production. Mazda and Honda also reported cheating on its vehicle testing. Mazda said incorrect engine control software was used in the tests. Meanwhile, the "improper tests" conducted by Honda included "those on noise levels and torque, on a range of models," according to the Associated Press. "Honda said affected older models -- the Accord, Odyssey and Fit -- are no longer in production. The safety of the vehicles is not affected, it said."

HP's MicroLED Monitors Stack Together Like Legos

Par : BeauHD
1 juin 2024 à 13:00
An anonymous reader quotes a report from Digital Trends: HP researchers have published a paper detailing a new modular monitor design they call "composable microLED monitors." Using advancing microLED tech to make smaller screens with no bezels, they imagine a Lego-like system that allows customers to buy different monitor modules and slot them together at home. In the paper, diagrams show "core units" with a direct connection to the host computer being expanded both horizontally and vertically with multiple extensions. The idea is that by choosing from flat or curved extension pieces and connecting them to the core unit, you can make a monitor in whatever size or shape you want. To keep assembly simple and effective, the design uses jigsaw-like connections alongside magnets to ensure each module automatically aligns correctly. And to prevent the number of possible configurations from getting out of hand, the design only allows extensions to attach to the sides or bottom of the square-shaped core unit. Once your strangely shaped monitor is complete, you would be able to choose how your operating system treats each part -- either as an extension of the core unit or as a separate screen. These settings would be controlled with physical switches on the modules that you could change whenever you wanted. As for the sizes of the modules, HP proposes a range of different possibilities, some more complicated than others. In an ideal situation, customers would be able to choose from either flat or curved core units and add flat or curved extensions of varying sizes. If that proved too difficult, curved monitor elements could be taken out of the picture completely, and customers would just add flat extensions to a flat core unit. As cool as this all sounds, there is a glaring problem -- how would the seams between each module look? Thanks to the bezel-less design, there at least wouldn't be a thick black divider between each part. However, a thin line or visible distortion would be inevitable. One approach HP proposes is minimizing the gap between each panel as much as possible and just accepting the thin line it creates. Alternatives include complicated techniques to disguise the joints using hardware or software solutions that modify the display of edge pixels to minimize visual joints. HP would have to find a balance between technical viability, cost, and customer feedback to determine the best overall solution.

Journalists 'Deeply Troubled' By OpenAI's Content Deals With Vox, The Atlantic

Par : BeauHD
1 juin 2024 à 10:00
Benj Edwards and Ashley Belanger reports via Ars Technica: On Wednesday, Axios broke the news that OpenAI had signed deals with The Atlantic and Vox Media that will allow the ChatGPT maker to license their editorial content to further train its language models. But some of the publications' writers -- and the unions that represent them -- were surprised by the announcements and aren't happy about it. Already, two unions have released statements expressing "alarm" and "concern." "The unionized members of The Atlantic Editorial and Business and Technology units are deeply troubled by the opaque agreement The Atlantic has made with OpenAI," reads a statement from the Atlantic union. "And especially by management's complete lack of transparency about what the agreement entails and how it will affect our work." The Vox Union -- which represents The Verge, SB Nation, and Vulture, among other publications -- reacted in similar fashion, writing in a statement, "Today, members of the Vox Media Union ... were informed without warning that Vox Media entered into a 'strategic content and product partnership' with OpenAI. As both journalists and workers, we have serious concerns about this partnership, which we believe could adversely impact members of our union, not to mention the well-documented ethical and environmental concerns surrounding the use of generative AI." [...] News of the deals took both journalists and unions by surprise. On X, Vox reporter Kelsey Piper, who recently penned an expose about OpenAI's restrictive non-disclosure agreements that prompted a change in policy from the company, wrote, "I'm very frustrated they announced this without consulting their writers, but I have very strong assurances in writing from our editor in chief that they want more coverage like the last two weeks and will never interfere in it. If that's false I'll quit.." Journalists also reacted to news of the deals through the publications themselves. On Wednesday, The Atlantic Senior Editor Damon Beres wrote a piece titled "A Devil's Bargain With OpenAI," in which he expressed skepticism about the partnership, likening it to making a deal with the devil that may backfire. He highlighted concerns about AI's use of copyrighted material without permission and its potential to spread disinformation at a time when publications have seen a recent string of layoffs. He drew parallels to the pursuit of audiences on social media leading to clickbait and SEO tactics that degraded media quality. While acknowledging the financial benefits and potential reach, Beres cautioned against relying on inaccurate, opaque AI models and questioned the implications of journalism companies being complicit in potentially destroying the internet as we know it, even as they try to be part of the solution by partnering with OpenAI. Similarly, over at Vox, Editorial Director Bryan Walsh penned a piece titled, "This article is OpenAI training data," in which he expresses apprehension about the licensing deal, drawing parallels between the relentless pursuit of data by AI companies and the classic AI thought experiment of Bostrom's "paperclip maximizer," cautioning that the single-minded focus on market share and profits could ultimately destroy the ecosystem AI companies rely on for training data. He worries that the growth of AI chatbots and generative AI search products might lead to a significant decline in search engine traffic to publishers, potentially threatening the livelihoods of content creators and the richness of the Internet itself.

'Planetary Parade' Will See Six Planets Line Up In the Morning Sky

Par : BeauHD
1 juin 2024 à 07:00
On June 3, a "planet parade" of six planets -- Jupiter, Mercury, Uranus, Mars, Neptune and Saturn -- will form a straight line through the pre-dawn sky. Astronomy.com reports: Some 20 minutes before sunrise, all six planets should be visible, though note that Uranus (magnitude 5.9) and Neptune (magnitude 7.8) will be too faint for naked-eye observing and, although they're present in the lineup, will need binoculars or a telescope to spot. But Jupiter (magnitude -2), Mercury (magnitude -1), Mars (magnitude 1), and Saturn (magnitude 1) will all stand out clearly to the naked eye in a line spanning some 73 degrees on the sky. What's more, a delicate waning crescent Moon is crashing the party as well, standing just to the lower left of Mars. Note, however, that our Moon is not perfectly in line -- that's because Luna's orbit is tilted some 5 degrees with respect to the ecliptic. The next morning, June 4, the crescent Moon does a little better, falling more closely in line a bit farther from Mars. But now Mercury has stepped out of place and stands to Jupiter's lower right (south) as the two planets reach a close conjunction just 7 degrees apart -- not to be missed, especially in binoculars or telescopes! By June 5, Mercury lies to Jupiter's lower left, replacing the gas giant as the easternmost point in the planetary lineup. And the nearly New Moon (just 2 percent lit) stands above the pair. As June progresses, Mercury quickly ducks out of view, passing close to the Sun before reappearing in the evening sky and leaving us with only five planets in the pre-dawn sky. But those planets continue to form a nice, clean line, stretching nearly 80 degrees from Jupiter to Saturn (with Uranus, Mars, and Neptune in between) by June 30. On this morning, the Moon as rejoined the line, once again a delicate waning crescent about 33 percent lit, hanging perfectly in place to Mars' upper right.

Scientists Find the Largest Known Genome Inside a Small Plant

Par : BeauHD
1 juin 2024 à 03:30
An anonymous reader quotes a report from the New York Times: Last year, Jaume Pellicer led a team of fellow scientists into a forest on Grande Terre, an island east of Australia. They were in search of a fern called Tmesipteris oblanceolata. Standing just a few inches tall, it was not easy to find on the forest floor. "It doesn't catch the eye," said Dr. Pellicer, who works at the Botanical Institute of Barcelona in Spain. "You would probably step on it and not even realize it." The scientists eventually managed to spot the nondescript fern. When Dr. Pellicer and his colleagues studied it in the lab, they discovered it held an extraordinary secret. Tmesipteris oblanceolata has the largest known genome on Earth. As the researchers described in a study published on Friday, the fern's cells contain more than 50 times as much DNA as ours do. [The analysis revealed the species T. oblanceolata to have a record-breaking genome size of 160.45 Gbp, which is about 7% larger than that of P. japonica (148.89 Gbp). For comparison, the human genome contains about 3.1 Gbp distributed across 23 chromosomes and when stretched out like a ball of yarn, the length of DNA in each cell only measures about 2m.] "Surprisingly, having a larger genome is usually not an advantage," notes Phys.org in a report. "In the case of plants, species possessing large amounts of DNA are restricted to being slow growing perennials, are less efficient at photosynthesis (the process by which plants convert the sun's energy into sugars) and require more nutrients (especially nitrogen and phosphates) to grow and compete successfully with their smaller-genomed neighbors. In turn, such effects may influence the ability of a plant to adapt to climate change and their risk of extinction." "In animals, some of the largest genomes include the marbled lungfish (Protopterus aethiopicus) at 129.90 Gbp and the Neuse River waterdog (Necturus lewisi) at 117.47 Gbp," reports Phys.org. "In stark contrast, six of the largest-known eukaryotic genomes are held by plants, including the European mistletoe (Viscum album) at 100.84 Gbp."

London's famed Evening Standard newspaper has announced plans to end its daily outlet, "bringing an end to almost 200 years of publication in the capital," reports The Guardian. Going forward, the company plans to launch "a brand new weekly newspaper later this year and consider options for retaining ES Magazine with reduced frequency," while also working to increase traffic to its website. "In its 197-year history the Evening Standard has altered its format, price, content and distribution models," notes The Guardian. "But giving up on producing a daily print newspaper is the biggest change yet." From the report: The newspaper said it has been hit hard by the introduction of wifi on the London Underground, a shortage of commuters owing to the growth of working from home and changing consumer habits. The Standard lost 84.5 million pounds in the past six years, according to its accounts, and is reliant on funding from its part-owner Evgeny Lebedev. Its other shareholders include a bank with close links to the Saudi government. Industry sources suggested Lebedev had been willing to consider selling the outlet in recent years but no buyer was found. Paul Kanareck, the newspaper's chair, told staff on Wednesday morning: "The substantial losses accruing from the current operations are not sustainable. Therefore, we plan to consult with our staff and external stakeholders to reshape the business, return to profitability and secure the long-term future of the number one news brand in London." Kanareck said there would be an "impact on staffing," with journalists bracing themselves for further job losses on top of years of redundancies, while design staff on the print edition are expected to be hit hard. Distributors who hand out the newspaper across London are also likely to be out of work, and billboards outside railway stations advertising the day's headline will stand empty on most days. He suggested there would be a change in focus for the weekly outlet: "A proposed new weekly newspaper would replace the daily publication, allowing for more in-depth analysis of the issues that matter to Londoners, and serve them in a new and relevant way by celebrating the best London has to offer, from entertainment guides to lifestyle, sports, culture and news and the drumbeat of life in the world's greatest city." Closing the Evening Standard will mean that for the first time in centuries, Londoners will have no general-interest daily print newspaper. The finance-focused City AM, which was recently saved by the billionaire Matthew Moulding, will continue to publish four days a week and has recently increased its distribution.
