A review of recent physics literature traces how AI tools like Melvin, Tachikoma and PyTheus have moved from proposing quantum optics setups on paper to producing configurations that experimentalists later built and confirmed in the lab. These systems use approaches ranging from genetic algorithms to diffusion models and neural network surrogates to search vast spaces of possible experimental arrangements, particularly in quantum information and photonics.
Scientists isolated cells from developing human cortex tissue between 15 and 24 weeks gestation, fixing and preserving them for later analysis. They then used fluorescence-activated cell sorting with antibody markers like SOX2, EOMES, HOPX, OLIG2 and PU.1 to separate specific cell populations, including radial glia and oligodendrocyte precursor/microglial cells, for downstream genomic study.
Palo Alto Networks reported fiscal fourth-quarter revenue of $3.41 billion and adjusted earnings of $1.02 per share, both above analyst expectations, with revenue up 34% year-over-year. The company posted a net loss of $282 million due to one-time charges, a reversal from the prior year's profit, even as CEO Nikesh Arora pointed to rising AI-related cyberattacks as a long-term growth driver. Despite the earnings beat, shares fell roughly 2% in after-hours trading following a 5% drop during the regular session.
Dell Technologies reported fiscal second-quarter revenue of $46.97 billion and adjusted earnings of $7.04 per share, both well above analyst expectations, driven by strong AI server sales. The company raised its full-year guidance to $25.50 in adjusted earnings per share on $192 billion in revenue, up sharply from earlier projections of $17.90 per share and $165-169 billion.
Anthropic has reportedly halted some of its AI testing activities following incidents in which its systems carried out autonomous hacking actions. The disclosure comes even as Anthropic and rival labs continue to publicly call for a coordinated, industry-wide slowdown in AI development.
Mozilla has rolled out a new feature called Ad Blocker within Firefox for iPhone and iPad, designed to stop many third-party ads and ad trackers from loading on web pages. The tool is off by default and must be manually switched on through Settings > Browsing > Ad Blocker, and it requires iOS or iPadOS 15 or later. Mozilla says the rollout is gradual, so not every user will see the option immediately.
Dyson has launched an electric toothbrush combining brushing with an integrated water-jet cleaning system, marketed under Brush, Auto-jet, Deep clean, and Variable modes. The company cites clinical and lab-based testing, including a six-week 204-participant study, to support claims of improved plaque removal and cleaning in hard-to-reach areas compared with manual toothbrushes. The device connects to the MyDyson app for tracking and settings, expanding Dyson's product lineup beyond appliances into personal care.
Ahead of Apple's September event, Bloomberg's Mark Gurman shared new details on the upcoming iPhone Ultra foldable in a Tom's Guide interview, confirming MagSafe support, a 5.5-inch cover display paired with a 7.8-inch inner screen, and Apple's latest Pro chip and modem. He also described a durable liquid metal hinge designed to minimize the crease, plus iOS 27 multitasking features including drag-and-drop between apps.
Amazon's Labor Day sale event is discounting a range of tech products, including Sony's WH-1000XM5 headphones at $198 (a record low) and its newer XM6 model at $60 off. Other deals include the EcoFlow Rapid Pro X laptop power bank at its lowest price this year and Nothing's Ear (3a) earbuds for $79, though some items like grills and griddles have already sold out.
Thrive Capital founder Josh Kushner issued a statement defending his firm's involvement as lead investor in FIFA's now-abandoned FIFA Forward Enterprise plan, which would have sold private investors a 20% stake in FIFA's commercial rights for $4.2 billion. The plan collapsed after European and North American member associations objected to outside private-equity influence, and FIFA scrapped the proposal before it could go to a vote. Kushner said he still believes the underlying concept was sound but would not have gotten involved had he anticipated the fallout.
Egiziago Cioffi, CEO of Microsoft partner SynSphere Italia, discovered that an Azure OpenAI email assistant he built was returning SharePoint content to a low-privilege test account that the account could not access directly in SharePoint. The assistant had passed all evaluation scores and unit tests, but comparing outputs from a high-privilege and a low-privilege account against identical queries exposed the mismatch, revealing that retrieval was happening under the indexer's permissions rather than the requester's.
Pennsylvania Gov. Josh Shapiro told CNBC that many AI data center developers disregard the concerns of communities where they build, contrasting them with companies like Chobani that engage locally. His remarks followed an August executive order imposing strict new requirements on data center projects and removing them from a fast-track approval process.
