South Korean officials said Monday they will conduct safety inspections of all Boeing 737-800 aircraft operated by the country's airlines, as they struggle to determine what caused a plane crash that killed 179 people a day earlier. From a report: Sunday's crash, the country's worst aviation disaster in decades, triggered an outpouring of national sympathy. Many people worry how effectively the South Korean government will handle the disaster as it grapples with a leadership vacuum following the recent successive impeachments of President Yoon Suk Yeol and Prime Minister Han Duck-soo, the country's top two officials, amid political tumult caused by Yoon's brief imposition of martial law earlier this month.

New acting President Choi Sang-mok on Monday presided over a task force meeting on the crash and instructed authorities to conduct an emergency review of the country's aircraft operation systems. "The essence of a responsible response would be renovating the aviation safety systems on the whole to prevent recurrences of similar incidents and building a safer Republic of South Korea," said Choi, who is also deputy prime minister and finance minister.

An anonymous reader shared this report from the Washington Post: Archer is aiming to launch its first commercially operated [and electrically-powered] flights with a pilot and passengers within a year in Abu Dhabi. A competitor, Joby Aviation, says it is aiming to launch passenger service in Dubai as soon as late 2025. Advancements in batteries and other technologies required for the futuristic tilt-rotor craft are moving so fast that they could soon move beyond the novelty stage and into broader commercial use in a matter of years. Both companies are laying plans to operate at the 2028 Olympics in Los Angeles...

Scaling the industry from a novelty ride for the wealthy to a broadly available commuter option will take billions more in start-up money, executives said, including building out a network of takeoff and landing areas (called vertiports) and charging stations. Some high-profile ventures have already faltered. A plan for air taxis to transport spectators around the Paris Olympics fizzled... Still, investors, including big names like Stellantis and Toyota, have poured money into Silicon Valley companies like Archer and Joby. Boeing and Airbus are developing their own versions. All are betting that quieter, greener and battery-powered aircraft can revolutionize the way people travel. Major U.S. airlines including American, Delta, Southwest and United also are building relationships and planting seeds for deals with air taxi companies.
Two interesting quotes from the article:

• "It feels like the modern-day American Dream, where you can invent a technology and actually bring it to market even [if it's] as crazy as what some people call flying cars."
  
  — Adam Goldstein, CEO of Archer Aviation.

• "They have created these amazing new aircraft that really 10 or 15 years ago would've been unimaginable. I think there's something innately attractive about being able to leapfrog all of your terrestrial obstacles. Who hasn't wished that if you live in the suburbs that, you know, something could drop into your cul-de-sac and 15 minutes later you're at the office."
  
  — Roger Connor, curator of the vertical flight collection at the Smithsonian's National Air and Space Museum.

An anonymous reader quotes a report from Ars Technica: Apparently Hertz's purging of electric vehicles from its fleet isn't going fast enough for the car rental giant. A Reddit user posted an offer they received from Hertz to buy the 2023 Tesla Model 3 they had been renting for $17,913. Hertz originally went strong into EVs, announcing a plan to buy 100,000 Model 3s for its fleet by the end of 2021, but 16 months later had acquired only half that amount. The company found that repair costs -- especially for Teslas, which averaged 20 percent more than other EVs -- were cutting into its profit margins. Customer demand was also not what Hertz had hoped for; last January, it announced plans to sell off 20,000 EVs.

Asking its customers if they want to purchase their rentals isn't a new strategy for Hertz. "By connecting our rental customers who opt into our emails to our sales channels, we're not only building awareness of the fact that we sell arsenal but also offering a unique opportunity to someone who may be in the market for the same car they have on rent," Hertz communications director Jamie Line told The Verge. Hertz is advertising a limited 12-month, 12,000-mile powertrain warranty for each EV, and customers will have seven days to return the car in case of profound buyer's regret.

Vacancies at open-air shopping centres in the US have dropped to historically low levels [non-paywalled source], defying forecasts of a retail apocalypse caused by the rise of ecommerce. From a report: Landlords of complexes anchored by big-box chains, discount merchants and supermarkets have gained power to raise rents as leases expire. New construction has been stymied by higher interest rates and soaring building costs.

Scarcity in the market had disproved long-standing beliefs about retail real estate, said Brandon Isner, head of retail research at Newmark, a commercial property broker. "They would say, 'Retail is overbuilt. Retail is struggling. Ecommerce is going to take over brick-and-mortar retail.' And really none of that has ended up to be true," Isner said. Retailers plan to expand further in the years ahead, led by discount chains favoured by inflation-weary consumers seeking deals. Off-price clothing and decor chains Burlington Stores, Ross Stores and TJX, parent of the Marshalls and TJ Maxx store chains, have together added 339 US stores in the past year. Walmart intends to add 150 US locations over the next five years.

Data center construction is driving an unprecedented influx of electricians to central Washington state, where abundant hydropower and tax incentives have attracted major tech companies building AI infrastructure, New York Times is reporting.

Microsoft alone projects needing 2,300 electricians in coming years for facilities across three counties along the Columbia River. Union electricians earning up to $2,800 weekly after taxes are transforming agricultural communities like Quincy, where data centers now account for 75% of local tax revenue.

While the construction boom has funded community improvements including a new high school, rising housing costs and limited long-term employment opportunities raise concerns about sustainable economic benefits for longtime residents.

Apple has no plans to develop its own search engine despite potential restrictions on its lucrative revenue-sharing deal with Google, citing billions in required investment and rapidly evolving AI technology as key deterrents, according to a court filing [PDF].

In a declaration filed with the U.S. District Court in Washington, Apple Senior Vice President Eddy Cue said creating a search engine would require diverting significant capital and employees, while recent AI developments make such an investment "economically risky."

Apple received approximately $20 billion from Google in 2022 under a deal that makes Google the default search engine on Safari browsers. This arrangement is now under scrutiny in the U.S. government's antitrust case against Google.

Cue said Apple lacks the specialized professionals and infrastructure needed for search advertising, which would be essential for a viable search engine. While Apple operates niche advertising like the App Store, search advertising is "outside of Apple's core expertise," he said. Building a search advertising business would also need to be balanced against Apple's privacy commitments, according to his declaration.

Berlin-based T2 Linux developer René Rebe is also long-time Slashdot reader ReneR — and popped by with a special announcement for the holidays: The T2 Linux team has unveiled T2 Linux SDE 24.12, codenamed "Sky's the Limit!", delivering a massive update for this highly portable source-based Linux distribution... With 3,280 package updates, 206 new features, and the ability to boot on systems with as little as 512MB RAM, this release further strengthens T2 Linux's position as the ultimate tool for developers working across diverse hardware and embedded systems.
Some highlights from Rene's announcement:

• "The release includes 37 pre-compiled ISOs with Glibc, Musl, and uClibc, supporting 25 CPU architectures like ARM(64), RISCV(64), Loongarch64, SPARC(64), and vintage retro computing platforms such as M68k, Alpha, and even initial Nintendo Wii U support added."

• " The Cosmic Desktop, a modern Rust-based environment, debuts alongside expanded application support for non-mainstream RISC architectures, now featuring LibreOffice, OpenJDK, and QEMU."

And T2sde.org gives this glimpse of the future:

"While initially created for the Linux kernel, T2 already has proof-of-concept support for building 'home-brew' pkg for Other OS, including: BSDs, macOS and Haiku. Work on alternative micro kernels, such as L4, Fuchsia, RedoxOS or integrating building 'AOSP' Android is being worked on as well."

Five years ago, journalist and sci-fi author Cory Doctorow published a short story that explored the radicalization of individuals denied healthcare coverage. As The Guardian notes in a recent article, the story "might seem eerily similar" to the recent shooting of UnitedHealthcare's CEO. While it appears that the alleged shooter never read the story, Doctorow said: "I feel like the most important thing about that is that it tells you that this is not a unique insight." Doctorow continued: "that the question that I had is a question other people have had." As an activist in favor of liberalizing copyright laws and a proponent of the Creative Commons organization, it's important to note that Doctorow advocates for systemic reform through collective action rather than violence. Here's an excerpt from the The Guardian's article: In Radicalized, one of four novellas comprising a science fiction novel of the same name, Doctorow charts the journey of a man who joins an online forum for fathers whose partners or children have been denied healthcare coverage by their insurers after his wife is diagnosed with breast cancer and denied coverage for an experimental treatment. Slowly, over the course of the story, the men of the forum become radicalized by their grief and begin plotting -- and executing -- murders of health insurance executives and politicians who vote against universal healthcare.

In the wake of the December 4 shooting of UnitedHealthcare CEO Brian Thompson, which unleashed a wave of outrage at the U.S. health system, Doctorow's novella has been called prescient. When the American Prospect magazine republished the story last week, it wrote: "It is being republished with permission for reasons that will become clear if you read it." But Doctorow doesn't think he was on to something that no one else in the U.S. understood. [...]

In one part of the story, a man whose young daughter died after an insurance company refused to pay for brain surgery bombs the insurer's headquarters. "It's not vengeance. I don't have a vengeful bone in my body. Nothing I do will bring Lisa back, so why would I want revenge? This is a public service. There's another dad just like me," he shares in a video message on the forum. "And right now, that dad is talking to someone at Cigna, or Humana, or BlueCross BlueShield, and the person on the phone is telling that dad that his little girl has. To. Die. Someone in that building made the decision to kill my little girl, and everyone else in that building went along with it. Not one of them is innocent, and not one of them is afraid. They're going to be afraid, after this."

"Because they must know in their hearts," he goes on. "Them, their lobbyists, the men in Congress who enabled them. They're parents. They know. Anyone who hurt their precious children, they'd hunt that person down like a dog. The only amazing thing about any of this is that no one has done it yet. I'm going to make a prediction right now, that even though I'm the first, I sure as hell will not be the last. There's more to come."

Longtime Slashdot reader timeOday shares a report from CNN: If all goes to plan, Virginia will be the site of the world's first grid-scale nuclear fusion power plant, able to harness this futuristic clean power and generate electricity from it by the early 2030s, according to an announcement Tuesday by the startup Commonwealth Fusion Systems. CFS, one of the largest and most-hyped nuclear fusion companies, will make a multibillion-dollar investment into building the facility near Richmond. When operational, the plant will be able to plug into the grid and produce 400 megawatts, enough to power around 150,000 homes, said its CEO Bob Mumgaard.

"This will mark the first time fusion power will be made available in the world at grid scale," Mumgaard said. Virginia Gov. Glenn Youngkin welcomed the announcement, calling it "an historic moment for Virginia and the world at large." The plant would represent a new stage in the quest to commercialize nuclear fusion, the process which powers the stars. But the path toward it is unlikely to be smooth, not least because the technology has not yet been proved viable.

The CDC has confirmed the first case of severe bird flu in the United States. NPR reports: Louisiana health officials initially reported the infection last week, saying a person was hospitalized after being exposed to sick and dead birds in backyard flocks. On Wednesday, the Centers for Disease Control and Prevention shared their findings that indicate the H5N1 virus responsible for the illness belongs to a genetic lineage that's circulating in wild birds and poultry -- different from what's spreading in dairy cattle and driving the majority of infections in agricultural workers.

In the U.S., more than 60 people have been infected so far, although some research suggests the official tally may be an undercount. The illnesses linked to dairy cattle have largely led to mild illnesses in humans.

The version of the virus in the Louisiana case is the so-called "D1.1 genotype." It has previously popped up in poultry workers in Washington state, who developed mild symptoms after testing positive in October. More recently, however, a teenager in British Columbia was hospitalized after contracting this D1.1 strain of the virus. Canadian health officials were unable to figure out how that person was infected. Dr. Demetre Daskalakis with the CDC, told reporters on Wednesday that bird blu has a well-established history of leading to severe illness and death. He added: "Infections without a clear source of exposure do occur, neither these cases nor the cases with known animal or animal products exposure have resulted in human to human transmission." California Gov. Gavin Newsom declared a state of emergency as the H5N1 bird flu virus moves from the Central valley to Southern California herds. The declaration will allow for a more streamlined approach among state and local agencies to tackle the virus, providing "flexibility around staffing, contracting, and other rules to support California's evolving response,'" reports the Los Angeles Times, citing a statement from Newsom's office.

"Building on California's testing and monitoring system -- the largest in the nation -- we are committed to further protecting public health, supporting our agriculture industry, and ensuring that Californians have access to accurate, up-to-date information," said Newsom in a statement. "While the risk to the public remains low, we will continue to take all necessary steps to prevent the spread of this virus."

An anonymous reader quotes a report from The Guardian: The UK's first driverless bus service, originally heralded as a breakthrough of global significance, is being withdrawn from service because too few passengers used it. The autonomous buses, operated by Stagecoach, have been running between Fife and Edinburgh along a 14-mile route over the Forth road bridge since May 2023 to relieve the heavy congestion which can bring traffic to a standstill.

The CAVForth service, a collaboration between Fusion Processing, the coach-building company Alexander Dennis, Napier University in Edinburgh and the Bristol Robotics Lab -- a joint venture between the University of Bristol and the University of the West of England -- was touted as the most ambitious and complex in the world. Built at an estimated cost of more than 6 million pounds, partly funded by the UK government, the fleet of five single-decker buses had the capacity to carry 10,000 passengers a week but needed two crew on board for safety reasons. Stagecoach said in a statement: "We are proud to have achieved a world first with our CAVForth autonomous bus service, demonstrating the potential for self-driving technology on a real-world registered timetable in East Scotland. Although passenger adoption did not meet expectations, the trial has significantly advanced the understanding of the operational and regulatory requirements for autonomous services, delivering what was expected from this demonstrator project. The partners remain committed to exploring new opportunities for self-driving technology in other areas across the UK, ensuring that this exciting innovation can play a transformative role in future transport networks."

An anonymous reader quotes a report from The Register: China's Electronics Video Industry Association last week signed off on a standard for a universal remote control -- a gadget Beijing thinks locals need because they're struggling with multiple remotes, but which is also a little more significant in other ways. The standard requires remote controls to allow voice control, and to use one of three means of wireless comms: Bluetooth, infrared, and Star Flash -- more on that later. It has been hailed as a boon for consumers who apparently struggle to find the right remote control to use as they navigate between televisions and set-top boxes.

This standard reportedly detects which device a user wants to control, makes the connection, and eases the chore of directing a stream from a set-top box to a display. Device-makers have been told that televisions and set-top boxes must support the standard, and they've quickly complied: local media report that Chinese consumer electronics outfit Konka has already delivered the first Smart TV capable of handling the universal remote. Building a standard ecosystem for universal remotes has obvious benefits for consumers, who should be able to use one unit across multiple devices and won't be tied to proprietary tech. But this move has other benefits for Beijing, thanks to its requirement to use China's home-grown Bluetooth alternative, Star Flash.

Star Flash is one of the projects run by the SparkLink Alliance -- a group that lists hundreds of Chinese developers and manufacturers as members. Huawei contributes tech to the group. Chinese IoT hardware vendor Qogrisys has described it as an upgrade to both Bluetooth and Wi-Fi that incorporates ideas used in 5G networks, is capable of handling multiple simultaneous device connections, sips power sparingly so battery-powered devices go longer between recharges, and can stream lossless stereo audio. Chinese consumer electronic and automotive brands are already keen to use Star Flash, and the Alliance is promoting its use in industrial settings too. China will promote use of universal remotes in 2025 -- meaning the protocol may soon appear in millions of domestic devices, giving manufacturers scale to justify further investment.

This month Bill Gates recommended four books about making sense of the world, including The Coming Wave, by Mustafa Suleyman. Gates calls it "the book I recommend more than any other on AI — to heads of state, business leaders, and anyone else who asks — because it offers something rare: a clear-eyed view of both the extraordinary opportunities and genuine risks ahead." After helping build DeepMind from a small startup into one of the most important AI companies of the past decade, [Suleyman] went on to found Inflection AI and now leads Microsoft's AI division. But what makes this book special isn't just Mustafa's firsthand experience — it's his deep understanding of scientific history and how technological revolutions unfold. He's a serious intellectual who can draw meaningful parallels across centuries of scientific advancement. Most of the coverage of The Coming Wave has focused on what it has to say about artificial intelligence — which makes sense, given that it's one of the most important books on AI ever written. And there is probably no one as qualified as Mustafa to write it...

But what sets his book apart from others is Mustafa's insight that AI is only one part of an unprecedented convergence of scientific breakthroughs. Gene editing, DNA synthesis, and other advances in biotechnology are racing forward in parallel. As the title suggests, these changes are building like a wave far out at sea — invisible to many but gathering force. Each would be game-changing on its own; together, they're poised to reshape every aspect of society... [P]rogress is already accelerating as costs plummet and computing power grows. Then there are the incentives for profit and power that are driving development. Countries compete with countries, companies compete with companies, and individuals compete for glory and leadership. These forces make technological advancement essentially unstoppable — and they also make it harder to control...

How do we limit the dangers of these technologies while harnessing their benefits? This is the question at the heart of The Coming Wave, because containment is foundational to everything else. Without it, the risks of AI and biotechnology become even more acute. By solving for it first, we create the stability and trust needed to tackle everything else... [Suleyman] lays out an agenda that's appropriately ambitious for the scale of the challenge — ranging from technical solutions (like building an emergency off switch for AI systems) to sweeping institutional changes, including new global treaties, modernized regulatory frameworks, and historic cooperation among governments, companies, and scientists...
In an accompanying Christmas-themed video, Gates adds that "Of all the books on AI, that's the one I recommend the most."

Gates also recommends The Anxious Generation by Jonathan Haidt, saying it "made me reflect on how much of my younger years — which were often spent running around outside without parental supervision, sometimes getting into trouble — helped shape who I am today. Haidt explains how the shift from play-based childhoods to phone-based childhoods is transforming how kids develop and process emotions." (In the video Gates describes it as "kind of a scary book, but very convincing. [Haidt] writes about the rise of mental illness, and anxiety in children. He, unlike some books, actually has some prescriptions, like kids not using phones until much later, parenting style differences. I think it's a super-important book.")

Gates goes into the book's thesis in a longer blog post: that "we're actually facing two distinct crises: digital under-parenting (giving kids unlimited and unsupervised access to devices and social media) and real-world over-parenting (protecting kids from every possible harm in the real world). The result is young people who are suffering from addiction-like behaviors — and suffering, period — while struggling to handle challenges and setbacks that are part of everyday life." [Haidt] makes a strong case for better age verification on social media platforms and delaying smartphone access until kids are older. Literally and figuratively, he argues, we also need to rebuild the infrastructure of childhood itself — from creating more engaging playgrounds that encourage reasonable risk-taking, to establishing phone-free zones in schools, to helping young people rediscover the joy of in-person interaction.
Gates also recommends Engineering in Plain Sight, by Grady Hillhouse, a book which he says "encourages curiosity." ("Hillhouse takes all of the mysterious structures we see every day, from cable boxes to transformers to cell phone towers, and explains what they are and how they work. It's the kind of read that will reward your curiosity and answer questions you didn't even know you had.")

And finally, Gates recommends an autobiography by 81-year-old Pulitzer Prize-winning historian/biographer/former sports journalist Doris Kearns Goodwin, who assesses the impact of President Lyndon Johnson's policies in a surprising "personal history of the 1960s."

"Proposals for a tunnel connecting the U.K. to the U.S. underneath the Atlantic Ocean have resurfaced," reports Newsweek, "but with a price tag of almost $20 trillion, the project is a big ask." With the two global cities being over 3,000 miles apart, construction would take several years — the 23.5-mile Channel Tunnel linking England and France took six years to construct — and require significant investment. Estimates over the cost have reached as high as £15.5 trillion, the equivalent of $19.8 trillion.

However, developments in vacuum tube technology have made the concept more viable. By creating a vacuum within the tunnel and using pressurized vehicles, trains traveling along the structure could theoretically reach speeds of more than 3,000 mph, making the journey between London and New York barely an hour long. This is because trains would not face any air resistance within the tunnel, allowing them to reach higher speeds than unconventional trains. This design, which has seen new development in Indian transportation, is sometimes called a "hyperloop". Cutting the intercontinental journey down to a matter of minutes means that for the first time, the Transatlantic Tunnel justifies the hefty price tag that undersea construction comes with, as it would become significantly more efficient and environmentally friendly than flying.
While no plans are underway, it's interesting to ask whether it could even be done. Weighing in, Elon Musk "has suggested the idea of building a '£20 trillion' underground tunnel link from London to New York appears to be a genuine possibility," according to the site LADbible, "although he says he could do it for less." (On X.com Musk posted that his Boring Company "could do it for 1000X less money.") This comes after the SpaceX boss, 53, who promises to revolutionise the way we travel, said his 'Starship' rocket could be used to transport passengers to any city in the world in under an hour.

Tucked away in a blog post about Google's quantum computing chip, Willow, Google Quantum AI founder Hartmut Neven wrote that the chip was so "mind-boggling" fast that it seemed to borrow computational power from other universes. According to Neven, the chip's performance suggests the existence of parallel universes, writing, "We live in a multiverse." TechCrunch reports: Here's the passage: "Willow's performance on this benchmark is astonishing: It performed a computation in under five minutes that would take one of today's fastest supercomputers 1025 or 10 septillion years. If you want to write it out, it's 10,000,000,000,000,000,000,000,000 years. This mind-boggling number exceeds known timescales in physics and vastly exceeds the age of the universe. It lends credence to the notion that quantum computation occurs in many parallel universes, in line with the idea that we live in a multiverse, a prediction first made by David Deutsch."

This drop-the-mic moment on the nature of reality was met with skepticism by some, but, surprisingly, others on the internet who profess to understand these things argued that Nevan's conclusions were more than plausible. The multiverse, while stuff of science fiction, is also an area of serious study by the founders of quantum physics. The skeptics, however, point out that the performance claims are based on the benchmark that Google itself created some years ago to measure quantum performance. That alone doesn't prove that parallel versions of you aren't running around in other universes -- just where the underlying measuring stick came from.

An anonymous reader quotes a report from Engadget: The United States Postal Service unveiled a plan to buy a fleet of all-electric mail trucks for its mail carriers back in 2022, of which 3,000 were supposed to be delivered by now. Unfortunately, those plans aren't even close to fruition. The Washington Post reported that defense contractor Oshkosh has only delivered 93 vehicles so far. [...]

The Washington Post obtained nearly 21,000 government and internal company records and spoke with 20 people familiar with the trucks' manufacturing and design process. Its reporting shows that Oshkosh ran into significant manufacturing delays of the electric NGDVs that caused lower than expected delivery numbers. Some of the anonymous sources said that engineers struggled to calibrate the mail trucks' airbags, and the vehicles' body and internal components are unable to contain water leaks to an alarming degree. The turnaround time for building these new mail trucks is also very slow. The Post reports that the South Carolina factory can only build one truck per day even though Oshkosh hoped it could build at least 80 vehicles a day by now.

Oshkosh also failed to inform the Postal Service about these delays. Four of the background sources say a senior company executive tried to update the Postal Service about these manufacturing issues only to have those efforts blocked by their corporate superiors. An Oshkosh spokesperson said in a statement that the defense contractor is still "fully committed to being a strong and reliable partner" with the Postal Services and insists "we remain on track to meet all delivery deadlines," according to The Post.

An anonymous reader quotes a report from CNBC: Legislation was introduced in the Texas House of Representatives on Thursday to establish a strategic bitcoin reserve, which could serve as a proving ground for the U.S. Treasury. The proposed bill would enable the state to start building a strategic bitcoin reserve by accepting taxes, fees and donations in bitcoin that would be held for a minimum of five years, Republican state Rep. Giovanni Capriglione announced on an X Spaces event Thursday.

The Texas bill aims to provide a way to strengthen the state's fiscal stability and establish it as a leader in bitcoin innovation, according to the Satoshi Action Fund, a nonprofit bitcoin advocacy group that worked with Capriglione on the bill. "Probably the biggest enemy of our investments is inflation," Capriglione said. "A strategic bitcoin reserve, investing in bitcoin, would be a win-win for the state." "I just filed the bill ... entitled 'An act relating to the establishment of a bitcoin reserve within the state treasury of Texas and the management of cryptocurrencies by governmental entities,'" he said later. "My goal is to make this bill as big and as broad as possible," Capriglione said. "This initial step is to allow some optionality and flexibility on it, but if I am able to get support from other legislators, we will make it even stronger."

It's "unlikely" a U.S. strategic bitcoin reserve will be established, "but it helps get animal spirits back into the market," Needham's John Todaro told CNBC. He said it's also "unlikely to drive material price gains, as we do not expect the U.S. government will purchase bitcoin in any meaningful capacity, but it's an item that drives excitement and optimism."

An anonymous reader quotes a report from Science Magazine: It would be a nightmare lab leak: Synthetic bacteria escape the petri dish and unleash a global plague that life on Earth is incapable of defending itself against. That's the concern raised by a group of eminent researchers in a Policy Forum published online today in Science. The commentary's 38 authors, from a broad range of disciplines, argue that governments worldwide should prohibit research and funding aimed at creating so-called mirror-image bacteria whose chemical makeup differs in a fundamental way from that of naturally existing organisms.

All of life's primary biomolecules can exist in two mirror-image forms, like a left and right hand. But only one form is found in nature. Proteins are left-handed, for example, and DNA and RNA are right-handed. Synthetic biologists have previously synthesized mirror-image proteins and genetic molecules. And mirror-image amino acids and peptides -- the building blocks of proteins -- have been incorporated into several approved drugs. Because natural enzymes struggle to break down mirror-image biomolecules, these components help the drugs survive longer in the body. [...]

The concern, he and others say, is that taking this line of work many steps further could result in fully mirror-image bacteria that could reproduce. Such organisms would likely be able to infect and potentially harm a wide range of microbes, plants, and animals while resisting the molecules that enable predators to kill and digest existing microbes. "They are essentially unassailable to those enzymes," says John Glass, a co-author and synthetic biologist at the J. Craig Venter Institute. Animals' immune systems would also struggle to cope with mirror bacteria. They "would be invisible to the immune system until it was too late," says Timothy Hand, a co-author and immunologist at the University of Pittsburgh. The Policy Forum authors acknowledge it will be at least a decade before synthetic biologists will be capable of creating these life forms. Nevertheless, they recommend halting all research aimed at that goal and urge funding agencies not to support it. "It's hard to overstate how severe these risks could be," says Ruslan Medzhitov, an immunologist at Yale University and one of the authors. "If mirror bacteria were to spread through infected animals and plants, much of the planet's many environments could be contaminated. ... Any exposure to contaminated dust or soil could be fatal."

Jack Szostak, a co-author and a 2019 Nobel Prize-winning chemist at the University of Chicago, adds: "The result could be catastrophic irreversible damage, perhaps far worse than any challenge we've previously encountered."

Google unveiled Gemini 2.0 yesterday, almost exactly one year after Google's initial Gemini launch. The new release offers enhanced multimodal capabilities like native image and audio output, real-time tool use, and advanced reasoning to enable agentic experiences, such as acting as a universal assistant or research companion. VentureBeat reports: During a recent press conference, Tulsee Doshi, director of product management for Gemini, outlined the system's enhanced capabilities while demonstrating real-time image generation and multilingual conversations. "Gemini 2.0 brings enhanced performance and new capabilities like native image and multilingual audio generation," Doshi explained. "It also has native intelligent tool use, which means that it can directly access Google products like search or even execute code."

The initial release centers on Gemini 2.0 Flash, an experimental version that Google claims operates at twice the speed of its predecessor while surpassing the capabilities of more powerful models. This represents a significant technical achievement, as previous speed improvements typically came at the cost of reduced functionality. Perhaps most significantly, Google introduced three prototype AI agents built on Gemini 2.0's architecture that demonstrate the company's vision for AI's future. Project Astra, an updated universal AI assistant, showcased its ability to maintain complex conversations across multiple languages while accessing Google tools and maintaining contextual memory of previous interactions. [...]

For developers and enterprise customers, Google introduced Project Mariner and Jules, two specialized AI agents designed to automate complex technical tasks. Project Mariner, demonstrated as a Chrome extension, achieved an impressive 83.5% success rate on the WebVoyager benchmark for real-world web tasks -- a significant improvement over previous attempts at autonomous web navigation. Supporting these advances is Trillium, Google's sixth-generation Tensor Processing Unit (TPU), which becomes generally available to cloud customers today. The custom AI accelerator represents a massive investment in computational infrastructure, with Google deploying over 100,000 Trillium chips in a single network fabric.

Google has announced an experimental AI-powered code agent called "Jules" that can automatically fix coding errors for developers. From a report: Jules was introduced today alongside Gemini 2.0, and uses the updated Google AI model to create multi-step plans to address issues, modify multiple files, and prepare pull requests for Python and Javascript coding tasks in GitHub workflows.

Microsoft introduced a similar experience for GitHub Copilot last year that can recognize and explain code, alongside recommending changes and fixing bugs. Jules will compete against Microsoft's offering, and also against tools like Cursor and even Claude and ChatGPT's coding abilities. Google's launch of a coding-focused AI assistant is no surprise -- CEO Sundar Pichai said in October that more than a quarter of all new code at the company is now generated by AI.

"Jules handles bug fixes and other time-consuming tasks while you focus on what you actually want to build," Google says in its blog post. "This effort is part of our long-term goal of building AI agents that are helpful in all domains, including coding."
