Parents who are worried about their children being on Roblox should not let them use it, the chief executive of the gigantic gaming platform has said. From a report: The site, which is the most popular in the UK among young gamers aged eight to 12, has been dogged by claims of some children being exposed to explicit or harmful content through its games, alongside multiple reported allegations of bullying and grooming.

But its co-founder and CEO Dave Baszucki insisted that the company is vigilant in protecting its users and pointed out that "tens of millions" of people have "amazing experiences" on the site. When asked what his message is to parents who don't want their children on the platform, Mr Baszucki said: "My first message would be, if you're not comfortable, don't let your kids be on Roblox." [...] "That sounds a little counter-intuitive, but I would always trust parents to make their own decisions," he told BBC News in an exclusive interview.

Using the Summit supercomputer at the Department of Energy's Oak Ridge National Laboratory, researchers have modeled a key component of nucleotide excision repair (NER) called the pre-incision complex (PInC), which plays a crucial role in DNA damage repair. Their study, published in Nature Communications, provides new insights into how the PInC machinery orchestrates precise DNA excision, potentially leading to advancements in treating genetic disorders, preventing premature aging, and understanding conditions like xeroderma pigmentosum and Cockayne syndrome. Phys.Org reports: "Computationally, once you assemble the PInC, molecular dynamics simulations of the complex become relatively straightforward, especially on large supercomputers like Summit," [said lead investigator Ivaylo Ivanov, a chemistry professor at Georgia State University]. Nanoscale Molecular Dynamics, or NAMD, is a molecular dynamics code specifically designed for supercomputers and is used to simulate the movements and interactions of large biomolecular systems that contain millions of atoms. Using NAMD, the research team ran extensive simulations. The number-crunching power of the 200-petaflop Summit supercomputer -- capable of performing 200,000 trillion calculations per second -- was essential in unraveling the functional dynamics of the PInC complex on a timescale of microseconds. "The simulations showed us a lot about the complex nature of the PInC machinery. It showed us how these different components move together as modules and the subdivision of this complex into dynamic communities, which form the moving parts of this machine," Ivanov said.

The findings are significant in that mutations in XPF and XPG can lead to severe human genetic disorders. They include xeroderma pigmentosum, which is a condition that makes people more susceptible to skin cancer, and Cockayne syndrome, which can affect human growth and development, lead to impaired hearing and vision, and speed up the aging process. "Simulations allow us to zero in on these important regions because mutations that interfere with the function of the NER complex often occur at community interfaces, which are the most dynamic regions of the machine," Ivanov said. "Now we have a much better understanding of how and from where these disorders manifest."

Google says its new open-source AI model, Gemma 3, achieves nearly the same performance as DeepSeek AI's R1 while using just one Nvidia H100 GPU, compared to an estimated 32 for R1. ZDNet reports: Using "Elo" scores, a common measurement system used to rank chess and athletes, Google claims Gemma 3 comes within 98% of the score of DeepSeek's R1, 1338 versus 1363 for R1. That means R1 is superior to Gemma 3. However, based on Google's estimate, the search giant claims that it would take 32 of Nvidia's mainstream "H100" GPU chips to achieve R1's score, whereas Gemma 3 uses only one H100 GPU.

Google's balance of compute and Elo score is a "sweet spot," the company claims. In a blog post, Google bills the new program as "the most capable model you can run on a single GPU or TPU," referring to the company's custom AI chip, the "tensor processing unit." "Gemma 3 delivers state-of-the-art performance for its size, outperforming Llama-405B, DeepSeek-V3, and o3-mini in preliminary human preference evaluations on LMArena's leaderboard," the blog post relates, referring to the Elo scores. "This helps you to create engaging user experiences that can fit on a single GPU or TPU host."

Google's model also tops Meta's Llama 3's Elo score, which it estimates would require 16 GPUs. (Note that the numbers of H100 chips used by the competition are Google's estimate; DeepSeek AI has only disclosed an example of using 1,814 of Nvidia's less-powerful H800 GPUs to server answers with R1.) More detailed information is provided in a developer blog post on HuggingFace, where the Gemma 3 repository is offered.

New submitter CInder123 shares a report from TechSpot: Apple is undertaking one of the most significant software overhauls in its history, aiming to revamp the user interface across iPhone, iPad, and Mac devices. This ambitious update, set for release later this year, will fundamentally transform the look and feel of Apple's operating systems, enhancing consistency and the user experience.

The updates are part of iOS 19 and iPadOS 19, codenamed "Luck," and macOS 16, dubbed "Cheer," according to Bloomberg's Mark Gurman. He cited sources who requested anonymity since the project has yet to be officially announced. These major upgrades will introduce a new design language while simplifying navigation and controls. Apple's push for consistency across platforms aims to create a seamless user experience when switching between devices. Currently, applications, icons, and window styles vary significantly across macOS, iOS, and visionOS, leading to a disjointed experience.

An anonymous reader quotes a report from Ars Technica: On Wednesday, Google DeepMind announced two new AI models designed to control robots: Gemini Robotics and Gemini Robotics-ER. The company claims these models will help robots of many shapes and sizes understand and interact with the physical world more effectively and delicately than previous systems, paving the way for applications such as humanoid robot assistants. [...] Google's new models build upon its Gemini 2.0 large language model foundation, adding capabilities specifically for robotic applications. Gemini Robotics includes what Google calls "vision-language-action" (VLA) abilities, allowing it to process visual information, understand language commands, and generate physical movements. By contrast, Gemini Robotics-ER focuses on "embodied reasoning" with enhanced spatial understanding, letting roboticists connect it to their existing robot control systems. For example, with Gemini Robotics, you can ask a robot to "pick up the banana and put it in the basket," and it will use a camera view of the scene to recognize the banana, guiding a robotic arm to perform the action successfully. Or you might say, "fold an origami fox," and it will use its knowledge of origami and how to fold paper carefully to perform the task.

In 2023, we covered Google's RT-2, which represented a notable step toward more generalized robotic capabilities by using Internet data to help robots understand language commands and adapt to new scenarios, then doubling performance on unseen tasks compared to its predecessor. Two years later, Gemini Robotics appears to have made another substantial leap forward, not just in understanding what to do but in executing complex physical manipulations that RT-2 explicitly couldn't handle. While RT-2 was limited to repurposing physical movements it had already practiced, Gemini Robotics reportedly demonstrates significantly enhanced dexterity that enables previously impossible tasks like origami folding and packing snacks into Zip-loc bags. This shift from robots that just understand commands to robots that can perform delicate physical tasks suggests DeepMind may have started solving one of robotics' biggest challenges: getting robots to turn their "knowledge" into careful, precise movements in the real world. DeepMind claims Gemini Robotics "more than doubles performance on a comprehensive generalization benchmark compared to other state-of-the-art vision-language-action models."

Google is advancing this effort through a partnership with Apptronik to develop next-generation humanoid robots powered by Gemini 2.0. Availability timelines or specific commercial applications for the new AI models were not made available.

D-Wave researchers have published findings in Science demonstrating what they call "quantum supremacy" by showing their quantum annealers can solve problems beyond the reach of classical computers. The team, led by Andrew D. King, demonstrated area-law scaling of entanglement in model quench dynamics of two-, three- and infinite-dimensional spin glasses.

The research shows quantum annealers rapidly generating samples that closely match solutions to the Schrodinger equation, supporting observed stretched-exponential scaling in matrix-product-state approaches. According to the paper, D-Wave's processors completed these magnetic materials simulations in under 20 minutes, while the same calculations would require nearly a million years on Oak Ridge National Laboratory's supercomputers.

The claim hasn't gone unchallenged. Miles Stoudenmire from the Flatiron Institute's Center for Computational Quantum Physics argues that classical computers can achieve comparable results using methods developed since D-Wave's initial findings. "We're just saying, 'Look, this one problem at this one time didn't beat classical computers. Try again,'" Stoudenmire noted. The quantum computing community has increasingly shifted terminology from "supremacy" to "advantage" or "utility," focusing on solving practical business or scientific problems faster, more accurately, or more economically than classical alternatives.

Several Asian airlines have tightened restrictions on portable battery chargers amid growing concerns about fire risks, following a January blaze that destroyed an Air Busan aircraft in South Korea. South Korean airlines now require passengers to keep portable chargers within arm's reach rather than in overhead bins, a rule implemented March 1 to ease public anxiety, according to the Transportation Ministry. Taiwan's EVA Air and China Airlines have banned using or charging power banks on flights but still allow them in overhead compartments.

Thai Airways announced a similar ban last Friday, citing "incidents of in-flight fires on international airlines." Battery-related incidents on U.S. airlines have increased from 32 in 2016 to 84 last year, with portable chargers identified as the most common culprit, according to Federal Aviation Administration data. The International Civil Aviation Organization has banned lithium-ion batteries from cargo holds since 2016, though no industry standard exists for regulating power banks.

Global sales of smartwatches have fallen for the first time, new figures indicate, in large part due to a sharp decline in the popularity of market leader, Apple. From a report: Market research firm Counterpoint says 7% fewer of the devices were shipped in 2024 compared to the year before. Shipments of Apple Watches fell by 19% in that period, Counterpoint says. It blames the slump on a lack of new features in Apple's latest devices, and the fact a rumoured high-end Ultra 3 model never materialised.

The Federal Trade Commission asked a judge in Seattle to delay the start of its trial accusing Amazon of duping consumers into signing up for its Prime program, citing resource constraints. CNBC: Attorneys for the FTC made the request during a status hearing on Wednesday before Judge John Chun in the U.S. District Court for the Western District of Washington. Chun had set a Sept. 22 start date for the trial. Jonathan Cohen, an attorney for the FTC, asked Chun for a two-month continuance on the case due to staffing and budgetary shortfalls.

The FTC's request to delay due to staffing constraints comes amid a push by the Trump administration's Department of Government Efficiency to reduce spending. DOGE, which is led by tech baron Elon Musk, has slashed the federal government's workforce by more than 62,000 workers in February alone. "We have lost employees in the agency, in our division and on our case team," Cohen said.

Amazon, Alphabet's Google and Meta Platforms on Wednesday said they support efforts to at least triple nuclear energy worldwide by 2050. From a report: The tech companies signed a pledge first adopted in December 2023 by more than 20 countries, including the U.S., at the U.N. Climate Change Conference. Financial institutions including Bank of America, Goldman Sachs and Morgan Stanley backed the pledge last year.

The pledge is nonbinding, but highlights the growing support for expanding nuclear power among leading industries, finance and governments. Amazon, Google and Meta are increasingly important drivers of energy demand in the U.S. as they build out AI centers. The tech sector is turning to nuclear power after concluding that renewables alone won't provide enough reliable power for their energy needs. Microsoft and Apple did not sign the statement.

An anonymous reader quotes a report from The Register: New York State has sued Allstate Insurance for operating websites so badly designed they would deliver personal information in plain-text to anyone that went looking for it. The data was lifted from Allstate's National General business unit, which ran a website for consumers who wanted to get a quote for a policy. That task required users to input a name and address, and once that info was entered, the site searched a LexisNexis Risk Solutions database for data on anyone who lived at the address provided. The results of that search would then appear on a screen that included the driver's license number (DLN) for the given name and address, plus "names of any other drivers identified as potentially living at that consumer's address, and the entire DLNs of those other drivers."

Naturally, miscreants used the system to mine for people's personal information for fraud. "National General intentionally built these tools to automatically populate consumers' entire DLNs in plain text -- in other words, fully exposed on the face of the quoting websites -- during the quoting process," the court documents [PDF] state. "Not surprisingly, attackers identified this vulnerability and targeted these quoting tools as an easy way to access the DLNs of many New Yorkers," according to the lawsuit. The digital thieves then used this information to "submit fraudulent claims for pandemic and unemployment benefits," we're told. ... [B]y the time the insurer resolved the mess, crooks had built bots that harvested at least 12,000 individuals' driver's license numbers from the quote-generating site.

Sphere Entertainment Co, the company behind the Las Vegas Sphere, said they are considering opening scaled-down versions of the immersive venue in other cities. AV Magazine reports: While this has been been feasible for its high-profile residencies such as U2, the Eagles, Dead & Company and Anyma, smaller venues could attract a broader range of artists who might not have the budget or demand to fill the flagship Las Vegas location. By scaling down the size while retaining the signature technology, Sphere Entertainment Co can offer a similar spectacle at a more sustainable cost for artists and spectators.

The possibility of mini-Spheres follows news that a full-scale venue will open in the UAE as a result of a partnership between Sphere Entertainment Co and the Department of Culture and Tourism -- Abu Dhabi. Beyond concerts, the Las Vegas Sphere has proven successful with immersive films such as V-U2: An Immersive Concert Film and the Sphere Expeience featuring Darren Aronofsky's Postcard from Earth, which In January passed 1,000 screenings. "As we enter a new fiscal year, we see significant opportunities to drive our Sphere business forward in Las Vegas and beyond," said Dolan. "We believe we are on a path toward realizing our vision for this next-generation medium and generating long-term shareholder value."

An anonymous reader quotes a report from the Washington Post: An Amazon-backed self-driving taxi failed to meet vehicle safety standardsbecause it lacks basics like a brake pedal and rearview mirrors, according to a report by federal inspectors that raises questions about the industry's plans to put a new generation of autonomous vehicles on U.S. roads. The National Highway Traffic Safety Administration report was produced as part of a review last year of an unusual vehicle by Amazon subsidiary Zoox that, without a steering wheel or other human controls, has no way for a person to drive. Zoox has asserted that the vehicle's technology, backed by artificial intelligence, complies with the agency's standards. But the NHTSA report documents "apparent noncompliances" with eight safety rules.

The contents of the previously undisclosed review suggest that rules written when autonomous vehicles were the stuff of futuristic musings pose a legal impediment to the industry's ambitions, even as plans for self-driving vehicles accelerate. Zoox has a small pilot fleet on the roads in California and Nevada and says it has completed thousands of trips carrying employees and guests. It is finalizing plans to launch public service in Las Vegas this year. [...] By documenting the apparent noncompliances of the Zoox, NHTSA could be setting the table for a recall, under agency procedures. It is unclear whether the Trump administration will attempt a change in course. The agency said it remains in discussion with Zoox and was "considering all options."

Zoox could have sought an exemption from the safety rules, but NHTSA has never granted one to an autonomous passenger vehicle. Instead, the company self-certified that its vehicle complied with the rules as it raced to be the first company to put a purpose-built robotaxi on the road and claim a share of what could become a multi trillion-dollar market. Zoox's vehicle bears little resemblance to a normal car. The plan is for customers to summon a ride using an app, much like a regular ride-hailing vehicle, getting in through bus-like doors and sitting facing one another. The vehicle navigates itself, seeing the world through a set of cameras and laser-based sensors. It largely relies on its own abilities to drive, but the company says teams of remote operators can seize control to help handle unusual situations. Passengers can call for assistance via a touch screen and open the doors using an emergency release. "We will continue to support transportation technology innovation while maintaining the safety of America's roads," NHTSA said in a statement.

"Our recent discussions with NHTSA are about mirrors, windshield wipers, a defroster, and a foot-activated brake pedal -- equipment that makes sense for vehicles with human drivers, but not for the Zoox purpose-built robotaxi," Zoox said in a statement. "Our purpose-built design means that the robotaxi can never be operated by a human driver, and our AI driver doesn't rely on this equipment to view the world."

Southwest Airlines boasts that its passengers' "bags fly free" -- but not for long. From a report: Starting May 28 -- just in time for the busy summer travel season -- only Southwest's most elite Rapid Rewards A-List Preferred members and passengers who book their top-tier Business Select fares will receive two free checked bags. Frequent flyer A-List Members, Southwest-branded credit card holders and other select customers will be allowed one checked bag.

Everyone else will be charged for their first and second checked bags on flights booked on or after May 28, the carrier says. It's a break with Southwest's 54 year history -- one that could undermine customer loyalty to the carrier, according to experts. "This is how you destroy a brand. This is how you destroy customer preference. This is how you destroy loyalty. And this, I think, is going to send Southwest into a financial tailspin," airline industry analyst Henry Harteveldt, of Atmosphere Research Group, told CBS News senior transportation correspondent Kris Van Cleave. "Southwest, with these changes, becomes just another airline."

Abstract of a paper published on Journal of Hospitality and Tourism Management:The adoption of digital menus accessed through quick response (QR) codes has witnessed a notable upsurge. Despite potential benefits for restaurant operators, the nuanced effects of QR code menus on customer behavior and experience remain relatively unknown. This research investigates the influence of menu presentation (QR code vs. traditional) on customer loyalty. In two studies, we find that QR code menus diminish customer loyalty (compared to traditional menus) due to perceived inconvenience. This effect is further moderated by customers' need for interaction. Our work is timely in highlighting the negative impact of perceptions of inconvenience on technology adoption.

SpaceX's Starlink has secured its first agreement in India, partnering with telecommunications leader Bharti Airtel to bring high-speed satellite internet to the world's most populous country, the companies announced Tuesday [PDF].

The landmark deal will enable Starlink to tap into Airtel's extensive retail network and ground infrastructure while expanding its global reach into previously underserved regions across India, pending regulatory authorizations.

"We are excited to work with Airtel and unlock the transformative impact Starlink can bring to the people of India," said Gwynne Shotwell, President and Chief Operating Officer of SpaceX. "The team at Airtel has played a pivotal role in India's telecom story, so working with them to complement our direct offering makes great sense for our business."

The collaboration will explore selling Starlink equipment through Airtel's retail stores and offering services to business customers while connecting communities in rural areas with limited connectivity.

An anonymous reader quotes a report from the BBC: A former senior Facebook executive has told the BBC how the social media giant worked "hand in glove" with the Chinese government on potential ways of allowing Beijing to censor and control content in China. Sarah Wynn-Williams -- a former global public policy director -- says in return for gaining access to the Chinese market of hundreds of millions of users, Facebook's founder, Mark Zuckerberg, considered agreeing to hiding posts that were going viral, until they could be checked by the Chinese authorities.

Ms Williams -- who makes the claims in a new book -- has also filed a whistleblower complaint with the US markets regulator, the Securities and Exchange Commission (SEC), alleging Meta misled investors. The BBC has reviewed the complaint. Facebook's parent company Meta, says Ms Wynn-Williams had her employment terminated in 2017 "for poor performance." It is "no secret we were once interested" in operating services in China, it adds. "We ultimately opted not to go through with the ideas we'd explored." Meta referred us to Mark Zuckerberg's comments from 2019, when he said: "We could never come to agreement on what it would take for us to operate there, and they [China] never let us in."

Facebook also used algorithms to spot when young teenagers were feeling vulnerable as part of research aimed at advertisers, Ms Wynn-Williams alleges. A former New Zealand diplomat, she joined Facebook in 2011, and says she watched the company grow from "a front row seat." Now she wants to show some of the "decision-making and moral compromises" that she says went on when she was there. It is a critical moment, she adds, as "many of the people I worked with... are going to be central" to the introduction of AI. In her memoir, Careless People, Ms Wynn-Williams paints a picture of what she alleges working on Facebook's senior team was like.

The Register's Simon Sharwood reports: The body that runs New Zealand's public health system uses a single Excel spreadsheet as the primary source of data to consolidate and manage its finances, which aren't in great shape perhaps due to the sheet's shortcomings. The spreadsheet-using agency is Health New Zealand (HNZ) which was established in 2022 to replace 20 district health boards in the expectation it would be more cost-effective and deliver more consistent services. The org has a budget of $NZ28 billion ($16 billion) and advised lawmakers it would stay within it for FY 23.24.

That prediction was incorrect and HNZ blew its budget, leading to a review of its finances that last week delivered a damming report [PDF] that found the org lost "control of the critical levers that drive financial outcomes" and had an "inability to identify and respond to the disconnect between expenditure and revenue." The Deloitte-penned report also found an Excel spreadsheet was the "primary data file used by HNZ to manage its financial performance" and was used for "consolidation, journals, business-critical reporting, and analysis."

The report also noted five big problems with the sheet used at HNZ:
- Financial information was often 'hard-coded,' making it difficult to trace to the source or have updated data flow through.
- Errors such as incorrectly releasing accruals or double-up releases were not picked up until following periods.
- Changes to prior periods and FTE errors in district financial reporting Excel submissions, would not flow through to consolidated file.
- The spreadsheet can be easy to manipulate information as there is limited tracking to source information where information is not flowing directly from accounting systems.
- It is highly prone to human error, such as accidental typing of a number or omission of a zero.
Relying on the spreadsheet also meant Health NZ moved slowly: The report found "monthly financial reporting usually took 12-15 days to consolidate and five days to analyze."

Dustin Moskovitz, CEO and co-founder of Asana, is stepping down and will transition to the role of Chair once a new CEO is appointed. "As I reflect on my journey since co-founding Asana nearly 17 years ago, I'm filled with immense gratitude," Moskovitz said in a statement. "Creating and leading Asana has been more than just building a company -- it's been a profound privilege to work alongside some of the most talented minds in the industry." Asana's stock price was down more than 25% following the news. CNBC reports: Asana said fourth-quarter sales rose 10% year over year to $188.3 million, which was in line with analysts' estimates. The company said its adjusted earnings per share was breakeven, ahead of analysts' estimates of a loss of one cent per share. Asana said it expects fiscal first-quarter revenue of $184.5 million to $186.5 million, trailing analysts' expectations of $191 million.

Moskovitz owns about 53% of the company's outstanding shares, between his Class A and Class B holdings. He has substantially increased his ownership since the company's public market debut in 2020. [...] Moskovitz said in his Monday retirement statement that he plans to focus more on his philanthropic endeavors, such as Good Ventures and Open Philanthropy, which cites "potential risks from advanced AI" among its various focus areas. In 2010, Moskovitz signed the Giving Pledge, a promise by some of the wealthiest people in the world to donate most of their fortunes to charity.

Internet shutdowns in Africa hit a record high in 2024, with 21 shutdowns across 15 countries. The previous record was 19 shutdowns in 2020 and 21. The Guardian reports: Authorities in Comoros, Guinea-Bissau and Mauritius joined repeat offenders such as Burundi, Ethiopia, Equatorial Guinea and Kenya. Guinea, Nigeria, Senegal and Tanzania were also on the list. But perpetrators also included militias and other non-state actors. Telecommunication and internet service providers who shut services based on government orders are also complicit in violating people's rights, said Felicia Anthonio, the #KeepItOn campaign manager at Access Now, citing the UN guiding principles on business and human rights.

The details showed that most of the shutdowns were imposed as a response to conflicts, protests and political instability. There were also restrictions during elections. [...] At least five shutdowns in Africa had been imposed for more than a year by the end of 2024, according to Access Now. As of early 2025, the social network Meta was still restricted in Uganda, despite authorities engaging with its representatives. On the Equatorial Guinean island of Annobon, internet and cell services have been cut off since an August 2024 protest over environmental concerns and isolation from the rest of the country. The increase in shutdowns led the African Commission on Human and Peoples' Rights to pass a landmark resolution in March 2024 to help reverse the trend.
