Walmart's market cap surpassed $1 trillion on Tuesday, putting the largest U.S. retail chain in an exclusive club dominated by tech groups. Bloomberg adds: The Bentonville, Arkansas-based chain -- a longtime favorite of bargain-hunting consumers -- has flexed its massive scale and supplier network to keep prices low and grab market share across the income spectrum. While Walmart has maintained its appeal to households looking for value, its online offerings are drawing new, wealthier shoppers seeking convenience.

An anonymous reader shares a report: Google Home users, your long nightmare is over. The platform has finally added support for buttons. The release notes for a February 2 update state that several new starter conditions for automations are now available, including "Switch or button pressed."

Smart buttons are physical, programmable switches that you can press to trigger automations or control devices in your smart home, such as turning lights on or off, opening and closing shades, running a Good Night scene, or starting a robot vacuum. A great alternative to voice and app control when you want to control multiple devices, smart buttons are often wireless and generally have several ways to press them: single press, double press, and long press, meaning one button can do multiple things.

Ultra-processed foods (UPFs) have more in common with cigarettes than with fruit or vegetables, and require far tighter regulation, according to a new report. The Guardian: UPFs and cigarettes are engineered to encourage addiction and consumption, researchers from three US universities said, pointing to the parallels in widespread health harms that link both.

UPFs, which are widely available worldwide, are food products that have been industrially manufactured, often using emulsifiers or artificial colouring and flavours. The category includes soft drinks and packaged snacks such as crisps and biscuits. There are similarities in the production processes of UPFs and cigarettes, and in manufacturers' efforts to optimise the "doses" of products and how quickly they act on reward pathways in the body, according to the paper from researchers at Harvard, the University of Michigan and Duke University.

They draw on data from the fields of addiction science, nutrition and public health history to make their comparisons, published on 3 February in the healthcare journal the Milbank Quarterly. The authors suggest that marketing claims on the products, such as being "low fat" or "sugar free," are "health washing" that can stall regulation, akin to the advertising of cigarette filters in the 1950s as protective innovations that "in practice offered little meaningful benefit."

Alphabet is plotting to dramatically expand its presence in India [non-paywalled source], with the possibility of taking millions of square feet in new office space in Bangalore, India's tech hub. From a report: Google's parent company has leased one office tower and purchased options on two others in Alembic City, a development in the Whitefield tech corridor, totaling 2.4 million square feet, according to people familiar with the deal. The first tower is expected to open to employees in the coming months, while construction on the remaining two is set to conclude next year.

Options in the real estate industry give would-be tenants the exclusive right to rent, or in some cases buy, a property at a predetermined price within a specific time frame. It's also possible Alphabet will not exercise the option to use the additional towers. If it does take all of the space, the complex could accommodate as many as 20,000 additional staff, which could more than double the company's footprint in India, said the people, asking not to be identified because the plans aren't public. Alphabet currently employs around 14,000 in the country, out of a global workforce of roughly 190,000.

[...] US President Donald Trump's visa restrictions have made it harder to bring foreign talent to America, prompting some companies to recruit more staff overseas. India has become an increasingly important place for US companies to hire, particularly in the race to dominate artificial intelligence.

Four economists across Central European University, Bielefeld University and the Kiel Institute have built a general equilibrium model of the open-source software ecosystem and concluded that vibe coding -- the increasingly common practice of letting AI agents select, assemble and modify packages on a developer's behalf -- erodes the very funding mechanism that keeps open-source projects alive.

The core problem is a decoupling of usage from engagement. Tailwind CSS's npm downloads have climbed steadily, but its creator says documentation traffic is down about 40% since early 2023 and revenue has dropped close to 80%. Stack Overflow activity fell roughly 25% within six months of ChatGPT's launch. Open-source maintainers monetize through documentation visits, bug reports, and community interaction. AI agents skip all of that.

The model finds that feedback loops once responsible for open source's explosive growth now run in reverse. Fewer maintainers can justify sharing code, variety shrinks, and average quality falls -- even as total usage rises. One proposed fix is a "Spotify for open source" model where AI platforms redistribute subscription revenue to maintainers based on package usage. Vibe-coded users need to contribute at least 84% of what direct users generate, or roughly 84% of all revenue must come from sources independent of how users access the software.

YouTube has confirmed that it is blocking background playback -- the ability to keep a video's audio running after minimizing the browser or locking the screen -- for non-Premium users across third-party mobile browsers including Samsung Internet, Brave, Vivaldi and Microsoft Edge.

Users began reporting the issue last week, noting that audio would cut out the moment they left the browser, sometimes after a brief "MediaOngoingActivity" notification flashed before media controls disappeared. A Google spokesperson told Android Authority that the platform "updated the experience to ensure consistency," calling background play a Premium-exclusive feature.

An anonymous reader shares a report: PayPal said on Tuesday it was booting its CEO and replacing him with its board chair Enrique Lores, sparing no ambiguity as to why: "The pace of change and execution was not in line with the Board's expectations," it said in a statement. One group that was blindsided was HP, where Lores was until Tuesday serving as CEO, according to people familiar with the matter.

Lores' switchup sent them rushing to launch a search process, those people said. HP's board does have internal candidates which it's considering for the top job, according to a person familiar with the board's thinking. As chair of PayPal's board, Lores played a role in a process evaluating internal and external candidates. It was unclear when or if he recused himself from the final decision to name him as CEO. But HP's board was only made aware that Lores was taking the CEO role at PayPal in recent weeks, the people said.

Adobe has emailed users of Adobe Animate to let them know the popular animation and game development program will be discontinued on March 1, an abrupt decision that has angered animators and game developers who say the tool remains an industry standard in television and game production.

Animate, the successor to the once-popular Flash, is widely used for graphic creation, animation and building games in HTML5. The company has not offered a reason for the shutdown. On BlueSky, artist and animator Julia Glassman wrote that many television productions, games, and animated media still rely on Animate and Flash pipelines and cannot simply pivot to entirely new software.

An anonymous reader shares a report: By now, the Forbes 30 Under 30 list has become more than a little notorious for the amount of entrants who go on to be charged with fraud.[...] Gokce Guven, a 26-year-old Turkish national and the founder and CEO of fintech startup Kalder, was charged last week with alleged securities fraud, wire fraud, visa fraud, and aggravated identity theft. The New York-based fintech startup -- which uses the "Turn Your Rewards into [a] Revenue Engine" tagline -- says it can help companies create and monetize individual rewards programs. The company was founded in 2022, and offers participating firms the opportunity to earn ongoing revenue streams via partner affiliate sales, Axios previously reported.

Guven was featured in last year's Forbes 30 Under 30 list. The magazine notes in the writeup that Guven's clients included major chocolatier Godiva and the International Air Transport Association, the trade organization that represents a majority of the world's airlines. Kalder also claims to have enjoyed the backing of a number of prominent VC firms. The U.S. Department of Justice alleges that, during Kalder's seed round in April of 2024, Guven managed to raise $7 million from more than a dozen investors after presenting a pitch deck that was rife with false information.

According to the government, Kalder's pitch deck claimed that there were 26 brands "using Kalder" and another 53 brands in "live freemium." However, officials say that, in reality, Kalder had, in many cases, only been offering heavily discounted pilot programs to many of those companies. Other brands "had no agreement with Kalder whatsoever -- not even for free services," officials said in a press release announcing the indictment. The pitch deck also "falsely reported that Kalder's recurring revenue had steadily grown month over month since February 2023 and that by March 2024, Kalder had reached $1.2 million in annual recurring revenue." The government also accuses Guven of having kept two separate sets of financial books.

The original Switch is officially Nintendo's best-selling console of all time after surpassing the DS handheld in lifetime sales. From a report: In its latest earnings release, Nintendo reports that the Nintendo Switch has, as of December 31, 2025, sold 155.37 million units since its launch in 2017, compared to 154.02 million units for the 2004 Nintendo DS.

In November, Nintendo reported that the Switch and DS were neck and neck. We expected the holiday sales period would see the Switch surpass the DS, even with Nintendo announcing that primary development would focus on the Switch 2. Nintendo previously said that it would continue to sell the original Switch "while taking consumer demand and the business environment into consideration."

Nintendo has to keep selling the Switch if it wants to dethrone Sony's PlayStation 2 as the best-selling video game console of all time. The PlayStation 2, discontinued in January 2013, sold more than 160 million units over its 13-year lifespan.

Elon Musk's SpaceX has acquired his AI startup xAI in an all-stock deal that values the combined entity at $1.25 trillion, ahead of what would be the largest initial public offering in history. SpaceX pegged its own valuation at $1 trillion -- a markup from the $800 billion it commanded in a December secondary stock sale -- and priced xAI at $250 billion based on a recent $20 billion funding round that valued the two-year-old AI company at $230 billion.

SpaceX CFO Bret Johnsen told investors on a call Monday that shares in the combined company would be priced at $527 and that xAI shares would convert into SpaceX stock at a roughly seven-to-one exchange rate. The company is still targeting a June IPO expected to raise as much as $50 billion, surpassing Saudi Aramco's $29 billion listing in 2019.

Musk said the least expensive way to do AI computation within two to three years will be in space. "Global electricity demand for AI simply cannot be met with terrestrial solutions, even in the near term, without imposing hardship on communities and the environment," he wrote. SpaceX filed last Friday for permission to launch up to a million satellites into Earth's orbit. xAI merged with Musk's social media platform X last March in a $113 billion deal, and Tesla announced a $2 billion investment in xAI last week.

Scientists at the University of Utah have analyzed nearly a century's worth of human hair samples and found that lead concentrations dropped 100-fold after the EPA began cracking down on leaded gasoline and other lead-based products in the 1970s.

The findings, published in the Proceedings of the National Academy of Sciences, drew on hair collected from Utah residents -- some preserved in family scrapbooks going back generations. Lead levels peaked between 1916 and 1969 at around 100 parts per million, fell to 10 ppm by 1990, and dropped below 1 ppm by 2024. The decline largely tracks the phase-out of leaded gasoline after President Nixon established the EPA in 1970; before the agency acted, most gasolines contained about 2 grams of lead per gallon, releasing nearly 2 pounds of lead per person into the environment each year.

The study arrives amid the Trump administration's broader push to scale back the EPA. Lead regulations have not yet been targeted, but the authors note concerns about loosened enforcement of the 2024 Lead and Copper rule on replacing old lead pipes.

The owners of Leica Camera AG -- Austrian billionaire Andreas Kaufmann and private equity giant Blackstone -- are considering a sale of a controlling stake in the German camera maker in a deal that could value the company at about $1.2 billion, Bloomberg reported, citing people familiar with the matter.

HSG, formerly known as Sequoia Capital China, and Altor Equity Partners are among a handful of bidders. The Kaufmann family could re-invest following a transaction. Leica traces its roots roughly 150 years to Ernst Leitz's microscope company and was publicly traded on the Frankfurt stock exchange until the Kaufmann family took it private in 2012.

An anonymous reader shares a report: The US Cybersecurity and Infrastructure Security Agency won't attend the annual RSA Conference in March, an agency spokesperson confirmed to The Register. Sessions involving speakers from the FBI and National Security Agency (NSA) have also disappeared from the agenda.

"Since the beginning of this administration, CISA has made significant progress in returning to our statutory, core mission and focusing on President Trump's policies for maximum security for all Americans," CISA spokesperson Marci McCarthy told us. "CISA has reviewed and determined that we will not participate in the RSA Conference since we regularly review all stakeholder engagements, to ensure maximum impact and good stewardship of taxpayer dollars."

McCarthy declined to comment on whether the decision had anything to do with former CISA director Jen Easterly being named chief executive of RSAC last week. Easterly, who was appointed to lead America's top cyber-defense agency under the Biden administration, joined her predecessor and CISA's first-ever director Chris Krebs in President Trump's line of fire back in July.

Microsoft is reevaluating its AI strategy on Windows 11 and plans to scale back or remove Copilot integrations across built-in apps after months of sustained user backlash, according to a Windows Central report citing people familiar with the company's plans.

Copilot features in apps like Notepad and Paint are under review and could be pulled entirely or stripped of their Copilot branding in favor of a more streamlined experience. The company has paused work on adding new Copilot buttons to any other in-box apps. Windows Recall, the screenshot-based search feature delayed by an entire year in 2024 over security and privacy concerns, is separately under review -- Microsoft internally considers the current implementation a failure and is exploring ways to rework or rename the feature rather than scrap it entirely, the report said.

Apple's long-standing dominance over its electronics supply chain is eroding as AI companies outbid the iPhone maker for critical components like chips, memory and specialized glass fiber, giving suppliers the leverage to demand that Apple pay more. CEO Tim Cook acknowledged the pressure during a Thursday earnings call, noting constraints in chip supplies and significant increases in memory prices.

Nvidia has overtaken Apple as TSMC's largest customer, CEO Jensen Huang said on a podcast; Apple had held that position by a wide margin for years. DRAM prices are set to quadruple from 2023 levels by year-end and NAND prices will more than triple, according to TechInsights.

The firm estimates Apple could pay $57 more for memory in the base iPhone 18 due this fall compared to the base iPhone 17 currently on sale -- a significant hit on a device that retails for $799.

Moltbook, a Reddit-like social network that launched last week and bills itself as a platform "built exclusively for AI agents," had a security vulnerability that exposed private messages shared between agents, the email addresses of more than 6,000 human owners, and over a million credentials, according to research published Monday by cybersecurity firm Wiz.

The flaw has since been fixed after Wiz contacted Moltbook. Wiz cofounder Ami Luttwak called it a classic byproduct of "vibe coding." Moltbook creator Matt Schlicht posted on X last Friday that he "didn't write one line of code" for the site. He did not immediately respond to a request for comment when reached out by Reuters. Luttwak said the vulnerability also allowed anyone to post to the site, bot or human. "There was no verification of identity," he said.
