Scientists at Zhejiang University have created the world's smallest LED display, featuring pixels just 90 nanometers wide -- roughly the size of a typical virus and too tiny to be seen with optical microscopes. The breakthrough, described in Nature this week, uses perovskite semiconductors that maintain brightness even at microscopic scales, giving them an advantage over conventional LEDs. The research team, led by Baodan Zhao, also demonstrated a larger display with pixels measuring about 100 micrometers (human hair width) that successfully rendered images including a spinning globe.

A United States District Court judge has approved a settlement between HP and customers who sued the company for firmware updates that prevented printers from working with non-HP ink cartridges. The class-action lawsuit, filed in December 2020, alleged HP "wrongfully compels users" to buy only HP ink by issuing updates that block competitors' cartridges. Under the settlement, HP admits no wrongdoing and won't pay monetary damages to affected customers, though it will pay $5,000 each to the three plaintiffs and $725,000 in attorneys' fees. HP has agreed to allow users of specific printer models impacted by the November 2020 update to decline firmware updates containing "Dynamic Security" features -- HP's term for technology that blocks cartridges using non-HP chips. The settlement applies only to 21 specific printer models, leaving numerous other HP printers subject to Dynamic Security restrictions. HP has previously paid millions in similar cases in Europe, Australia, and California related to printer bricking.

Over the past two decades, school districts have spent billions equipping classrooms with laptops, yet students have fallen further behind on essential skills, Michael Bloomberg argues. With about 90% of schools now providing these devices, test scores hover near historic lows -- only 28% of eighth graders proficient in math and 30% in reading. Bloomberg notes technology's classroom push came from technologists and government officials who envisioned tailored curricula. Computer manufacturers, despite good intentions, had financial interests and profited substantially. The Google executive who questioned why children should learn equations when they could Google answers might now ask why they should write essays when chatbots can do it for them. Studies confirm traditional methods -- reading and writing on paper -- remain superior to screen-based approaches. Devices distract students, with research showing up to 20 minutes needed to refocus after nonacademic activities. As some districts ban smartphones during school hours, Bloomberg suggests reconsidering classroom computer policies, recommending locked carts for more purposeful use and greater transparency for parents about screen time. Technology's promise has failed while imposing significant costs on children and taxpayers, he writes. Bloomberg calls for a return to books and pens over laptops and tablets.

A new AI system called Aardvark could deliver weather forecasts as accurate as those from advanced public weather services but run on desktop computers, according to a project unveiled Thursday and published in Nature. Developed by the UK's Alan Turing Institute with partners including Cambridge University, the European Centre for Medium-Range Weather Forecasts and Microsoft, Aardvark aims to make sophisticated forecasting accessible to countries with fewer resources, particularly in Africa. The system has already outperformed the US Global Forecast System on many variables in testing. Project leader Richard Turner noted the system is "completely open source" and not planned for commercialization by Microsoft.

IBM is laying off thousands of employees across the United States, with approximately 25% of staff at its Cloud Classic operation affected, The Register reports, citing a source. "Concrete numbers are being kept private," a source told the publication. "It is in the thousands." Staff reductions have occurred in Raleigh, North Carolina; New York; Dallas, Texas; and California, the report said. Affected departments include consulting, corporate social responsibility, cloud infrastructure, sales, and internal systems teams. The report adds: With regard to IBM Cloud Classic -- the infrastructure-as-a-service (IaaS) outfit offering built on IBM's 2013 acquisition of SoftLayer -- another source told us: "It's a resource action. I don't know how many people are in IaaS classic. They don't typically make that information easy to find. What I can say is that they have been making a lot of changes to shift employment to India as much as possible." A third source, newly let go by Big Blue, said it was fair to characterize this a layoff. "Everyone I know that was affected, myself included, was simply offered a separation agreement," this individual said, estimating that 10 percent of the Cloud group (which is not the same as Cloud Classic) has been let go.

Apple is undergoing a rare shake-up of its executive ranks, aiming to get its artificial intelligence efforts back on track after months of delays and stumbles, Bloomberg News reported Thursday, citing people familiar with the matter. From the report: Chief Executive Officer Tim Cook has lost confidence in the ability of AI head John Giannandrea to execute on product development, so he's moving over another top executive to help: Vision Pro creator Mike Rockwell. In a new role, Rockwell will be in charge of the Siri virtual assistant, according to the people, who asked not to be identified because the moves haven't been announced. Rockwell will report to software chief Craig Federighi, removing Siri completely from Giannandrea's command. Apple is poised to announce the changes to employees this week. The iPhone maker's senior leaders -- a group known as the Top 100 -- just met at a secretive, annual offsite gathering to discuss the future of the company. Its AI efforts were a key talking point at the summit, Bloomberg News has reported. The moves underscore the plight facing Apple: Its AI technology is severely lagging industry rivals, and the company has shown little sign of catching up. The Apple Intelligence platform was late to arrive and largely a flop, despite being the main selling point for the iPhone 16. Further reading: 'Something Is Rotten in the State of Cupertino'

Cosmologists have uncovered stronger evidence that dark energy -- the mysterious force accelerating cosmic expansion -- may be weakening over time. The Dark Energy Spectroscopic Instrument (DESI) collaboration presented their latest findings at the Global Physics Summit in Anaheim, California, reinforcing their preliminary results from last year. The DESI team analyzed data from approximately 15 million galaxies collected over three years, more than doubling their previous dataset of 6 million galaxies. Combined with supernova observations and cosmic microwave background data, their analysis shows a 4.2-sigma deviation from the standard Lambda-CDM cosmological model, which assumes dark energy remains constant. "We are much more certain than last year that this is definitely a thing," said Seshadri Nadathur of the University of Portsmouth, a key DESI researcher. These findings align with recent independent results from the Dark Energy Survey (DES), which earlier this month reported a similar 3.2-sigma tension with Lambda-CDM -- a tension that disappears if dark energy is allowed to vary. If confirmed, evolving dark energy could fundamentally alter cosmologists' understanding of the universe's ultimate fate. Instead of expanding indefinitely until all particles become impossibly separated, the universe might follow alternative trajectories. "It challenges the fate of the universe," explained Mustapha Ishak-Boushaki from the University of Texas at Dallas. "It's game-changing." Moreover, these findings challenge the simplest explanation of dark energy as vacuum energy, which quantum physics suggests should remain constant. Instead, the results indicate unknown physics, possibly involving a new particle, a modification to Einstein's theory of gravity, or even a new fundamental theory. DESI will continue observing through 2026, eventually producing a final map expected to include 50 million galaxies, potentially providing definitive evidence for this cosmic paradigm shift.

Pebble founder Eric Migicovsky has warned that the company's revived smartwatch line will face significant functionality limitations when paired with iPhones, blaming Apple's restrictive policies that favor its own Apple Watch. "It's impossible for a 3rd party smartwatch to send text messages, or perform actions on notifications (like dismissing, muting, replying) and many, many other things," Migicovsky wrote in a blog post, adding that the situation has "actually gotten worse over the last 8 years." A 2024 class action lawsuit cited in the post claims Apple has added further restrictions since iOS 13, including requiring users to display full content previews on their lock screens for notifications to reach third-party watches. Pebble is still developing an iOS app because 40% of potential customers use iPhones, he said. Migicovsky warned that the watch will "always appear to have less developed functionality on iOS than Android" and some features will arrive on Android first.

The credit-card market has quietly split in two, Atlantic argues in a new story: one offering generous benefits to wealthy Americans, the other offering expensive debt to the poor. Credit-card balances have reached an all-time high of $1.2 trillion, with serious delinquency rates climbing to their highest point since the Great Recession. "Transactors" pay off balances monthly and earn valuable rewards worth up to $3,000 annually in taxable income equivalent, while "revolvers" carry balances at a brutal 21.5% average APR. The poor subsidize the rich through two mechanisms: swipe fees that drive up retail prices by $1,700 annually for the average family, and late fees and interest charges that finance rewards programs. Interest revenue for credit-card companies has ballooned from $76 billion in 2020 to $170 billion in 2024. The economy now appears to be slowing down. High-income families are increasingly resembling working-class families in credit data, with three in five households earning over $80,000 annually carrying balances for more than a year. Card companies are now offering fewer cards to subprime borrowers, creating a troubling dilemma - while expensive credit cards are harmful, having no credit access might be worse. Bipartisan legislation now aims to cap interest rates and lower swipe fees.

The National Archives has released thousands of pages of declassified records related to the assassination of President John F. Kennedy in 1963. From a report: The records were posted to the National Archives' website, joining recently released records posted in 2023, 2022, 2021 and 2017-2018. "This release consists of approximately 80,000 pages of previously-classified records that will be published with no redactions," said the announcement from the Office of the Director of National Intelligence. "Additional documents withheld under court seal or for grand jury secrecy, and records subject to section 6103 of the Internal Revenue Code, must be unsealed before release." President Donald Trump signed an executive order on Jan. 23 directing the release of all remaining records related to the assassination, saying it was in the "public interest" to do so. Tuesday's initial release contained 1,123 records comprising 32,000 pages. A subsequent release on Tuesday night contained 1,059 records comprising 31,400 additional pages.

Nvidia has not been approached about acquiring a stake in Intel, CEO Jensen Huang said on Wednesday, addressing speculation about potential semiconductor industry consolidation. "Nobody's invited us to a consortium," Huang told reporters at Nvidia's annual developer conference. "Nobody invited me. Maybe other people are involved, but I don't know. There might be a party. I wasn't invited." Reuters previously reported that Taiwan Semiconductor Manufacturing Co (TSMC) had approached Nvidia, Broadcom and Advanced Micro Devices about joining a potential joint venture to operate Intel's factories. Other media outlets reported Intel was considering separating its manufacturing operations with U.S. President Donald Trump's support, potentially transferring control to a TSMC-led consortium.

OpenAI has launched a more powerful version of its o1 "reasoning" AI model, o1-pro, in its developer API. From a report: According to OpenAI, o1-pro uses more computing than o1 to provide "consistently better responses." Currently, it's only available to select developers -- those who've spent at least $5 on OpenAI API services -- and it's pricey. Very pricey. OpenAI is charging $150 per million tokens (~750,000 words) fed into the model and $600 per million tokens generated by the model. That's twice the price of OpenAI's GPT-4.5 for input and 10x the price of regular.

An anonymous reader shares a report: LG has ceased its XR product commercialization efforts, it confirmed, though will still continue long-term R&D. The news of LG ending its XR product plans was first reported by South Korean news outlet The Bell, citing an industry source. In a statement given to the outlet, LG confirmed the claim but clarified that it will still continue long-term XR research and development. According to The Bell, LG took the decision because it believes the XR market isn't growing as quickly as it expected, and it wants to focus more on heating, ventilation, air conditioning (HVAC) and robotics.

An anonymous reader shares a report: PCI Express 7 is nearing completion, the PCI Special Interest Group said, and the final specification should be released later this year. PCI Express 7, the backbone of the modern motherboard, is at the stage 0.9, which the PCI-SIG characterizes as the "final draft" of the specification. The technology was at version 0.5 a year ago, almost to the day, and originally authored in 2022. The situation remains the same, however. While modern PC motherboards are stuck on PCI Express 5.0, the specification itself moves ahead. PCI Express has doubled the data rate about every three years, from 64 gigtransfers per second in PCI Express 6.0 to the upcoming 128 gigatransfers per second in PCIe 7. (Again, it's worth noting that PCIe 6.0 exists solely on paper.) Put another way, PCIe 7 will deliver 512GB/s in both directions, across a x16 connection. It's worth noting that the PCI-SIG doesn't see PCI Express 7 living inside the PC market, at least not initially. Instead, PCIe 7 is expected to be targeted at cloud computing, 800-gigabit Ethernet and, of course, artificial intelligence. It will be backwards-compatible with the previous iterations of PCI Express, the SIG said.

EU antitrust regulators ordered Apple on Wednesday to open its closed ecosystem to competitors, detailing how the company must comply with the bloc's Digital Markets Act or face potential fines. The European Commission's decision comes six months after initiating proceedings against the tech giant. The first order requires Apple to grant rival smartphone, headphone and VR headset manufacturers access to its technology for seamless connectivity with Apple devices. A second order establishes specific processes for responding to app developers' interoperability requests. Apple criticized the decision, saying: "Today's decisions wrap us in red tape, slowing down Apple's ability to innovate for users in Europe." EU antitrust chief Teresa Ribera countered: "We are simply implementing the law." Non-compliance could trigger investigations resulting in fines up to 10% of Apple's global annual sales.
