PayPal has launched "Pay with Crypto" for U.S. merchants, enabling acceptance of over 100 cryptocurrencies with lower cross-border transaction fees and instant conversion to USD or its stablecoin PYUSD. "Businesses of all sizes face incredible pressure when growing globally, from increased costs for accepting international payments to complex integrations," said Alex Chriss, president and chief executive of PayPal. "Today, we're removing these barriers and helping every business of every size achieve their goals. [...] By enabling seamless cross-border crypto payments, we're breaking longstanding barriers in global commerce." SiliconANGLE reports: Using the new Pay with Crypto, merchants can now accept payments in the form of numerous cryptocurrency tokens, including bitcoin, Ethereum, USD Tether and Solana. The transaction fee rate will be 0.99% for the first year, increasing to 1.5% thereafter. The company said that rate is significantly lower than international credit card fees. "Imagine a shopper in Guatemala buying a special gift from a merchant in Oklahoma City," added Chriss. "Using PayPal's open platform, the business can accept crypto for payments, increase their profit margins, pay lower transaction fees, and get near instant access to proceeds." Merchants who accept cryptocurrency tokens can instantly convert them to dollars or PYUSD, the company's stablecoin, which is a type of cryptocurrency that maintains parity with USD so that every token is always worth $1. Funds stored as PYUSD on PayPal also earn 4% annual rewards. The company said the new service will roll out for U.S. merchants in the coming weeks. [...] Pay with Crypto will initially support cryptocurrency wallets from Coinbase, OKX, Binance, Kraken, Phantom, MetaMask and Exodus, with more planned.

A new study analyzing distorted sound waves from the early universe suggests we may live in a massive cosmic void "with roughly 20% lower than the average density of matter," writes Indranil Banik in an article for The Conversation. "Not every physicist is convinced that this is the case. But our recent paper analyzing distorted sounds from the early universe, published in the Monthly Notices of the Royal Astronomical Society, strongly backs up the idea." Slashdot reader alternative_right shares an excerpt from the report: My colleagues and I previously argued that the Hubble tension might be due to our location within a large void. That's because the sparse amount of matter in the void would be gravitationally attracted to the more dense matter outside it, continuously flowing out of the void. In previous research, we showed that this flow would make it look like the local universe is expanding about 10% faster than expected. That would solve the Hubble tension. But we wanted more evidence. And we know a local void would slightly distort the relation between the BAO angular scale and the redshift due to the faster moving matter in the void and its gravitational effect on light from outside. So in our new paper, Vasileios Kalaitzidis and I set out to test the predictions of the void model using BAO measurements collected over the last 20 years. We compared our results to models without a void under the same background expansion history. In the void model, the BAO ruler should look larger on the sky at any given redshift. And this excess should become even larger at low redshift (close distance), in line with the Hubble tension. The observations confirm this prediction. Our results suggest that a universe with a local void is about one hundred million times more likely than a cosmos without one, when using BAO measurements and assuming the universe expanded according to the standard model of cosmology informed by the CMB. Our research shows that the ACDM model without any local void is in "3.8 sigma tension" with the BAO observations. This means the likelihood of a universe without a void fitting these data is equivalent to a fair coin landing heads 13 times in a row. By contrast, the chance of the BAO data looking the way they do in void models is equivalent to a fair coin landing heads just twice in a row. In short, these models fit the data quite well. In the future, it will be crucial to obtain more accurate BAO measurements at low redshift, where the BAO standard ruler looks larger on the sky -- even more so if we are in a void. The average expansion rate so far follows directly from the age of the universe, which we can estimate from the ages of old stars in the Milky Way. A local void would not affect the age of the universe, but some proposals do affect it. These and other probes will shed more light on the Hubble crisis in cosmology.

An anonymous reader quotes a report from Polygon: In the wake of storefronts like Steam and itch.io curbing the sale of adult games, irate fans have started an organized campaign against the payment processors that they believe are responsible for the crackdown. While the movement is still in its early stages, people are mobilizing with an eye toward overwhelming communication lines at companies like Visa and Mastercard in a way that will make the concern impossible to ignore. On social media sites like Reddit and Bluesky, people are urging one another to get into contact with Visa and Mastercard through emails and phone calls. Visa and Mastercard have become the targets of interest because the affected storefronts both say that their decisions around adult games were motivated by the danger of losing the ability to use major payment processors while selling games. These payment processors have their own rules regarding usage, but they are vaguely defined. But losing infrastructure like this could impact audiences well beyond those who care about sex games, spokespeople for Valve and itch.io said. In a now-deleted post on the Steam subreddit with over 17,000 upvotes, commenters say that customer service representatives for both payment processors seem to already be aware of the problem. Sometimes, the representatives will say that they've gotten multiple calls on the subject of adult game censorship, but that they can't really do anything about it. The folks applying pressure know that someone at a call center has limited power in a scenario like this one; typically, agents are equipped to handle standard customer issues like payment fraud or credit card loss. But the point isn't to enact change through a specific phone call: It's to cause enough disruption that the ruckus theoretically starts costing payment processors money. "Emails can be ignored, but a very very long queue making it near impossible for other clients to get in will help a lot as well," reads the top comment on the Reddit thread. In that same thread, people say that they're hanging onto the call even if the operator says that they'll experience multi-hour wait times presumably caused by similar calls gunking up the lines. Beyond the stubbornness factor, the tactic is motivated by the knowledge that most customer service systems will put people who opt for call-backs in a lower priority queue, as anyone who opts in likely doesn't have an emergency going on. "Do both," one commenter suggests. "Get the call back, to gum up the call back queue. Then call in again and wait to gum up the live queue." People are also using email to voice their concerns directly to the executives at both Visa and Mastercard, payment processors that activist group Collective Shout called out by name in their open letter requesting that adult games get pulled. Emails are also getting sent to customer service.

Anthropic will implement weekly rate limits for Claude subscribers starting August 28 to address users running its Claude Code AI programming tool continuously around the clock and to prevent account sharing violations. The new restrictions will affect Pro subscribers paying $20 monthly and Max plan subscribers paying $100 and $200 monthly, though Anthropic estimates fewer than 5% of current users will be impacted based on existing usage patterns. Pro users will receive 40 to 80 hours of Sonnet 4 access through Claude Code weekly, while $100 Max subscribers get 140 to 280 hours of Sonnet 4 plus 15 to 35 hours of Opus 4. The $200 Max plan provides 240 to 480 hours of Sonnet 4 and 24 to 40 hours of Opus 4. Claude Code has experienced at least seven outages in the past month due to unprecedented demand.

After filing for bankruptcy, Norwegian smart home company Futurehome abruptly transitioned its Smarthub II and other devices to a subscription-only model, disabling essential features unless users pay an annual fee. Needless to say, customers aren't too happy with the move as they bought the hardware expecting lifetime functionality and now find their smart homes significantly less smart. Ars Technica reports: Launched in 2016, Futurehome's Smarthub is marketed as a central hub for controlling Internet-connected devices in smart homes. For years, the Norwegian company sold its products, which also include smart thermostats, smart lighting, and smart fire and carbon monoxide alarms, for a one-time fee that included access to its companion app and cloud platform for control and automation. As of June 26, though, those core features require a 1,188 NOK (about $116.56) annual subscription fee, turning the smart home devices into dumb ones if users don't pay up. "You lose access to controlling devices, configuring; automations, modes, shortcuts, and energy services," a company FAQ page says. You also can't get support from Futurehome without a subscription. "Most" paid features are inaccessible without a subscription, too, the FAQ from Futurehome, which claims to be in 38,000 households, says. After June 26, customers had four weeks to continue using their devices as normal without a subscription. That grace period recently ended, and users now need a subscription for their smart devices to work properly. Some users are understandably disheartened about suddenly having to pay a monthly fee to use devices they already purchased. More advanced users have also expressed frustration with Futurehome potentially killing its devices' ability to work by connecting to a local device instead of the cloud. In its FAQ, Futurehome says it "cannot guarantee that there will not be changes in the future" around local API access. Futurehome claims that introducing the subscription fee was a necessary move due to its recent bankruptcy. Its FAQ page reads: "Futurehome AS was declared bankrupt on 20 May 2025. The platform and related services were purchased from the bankruptcy estate -- 50 percent by former Futurehome owners and 50 percent by Sikom Connect -- and are now operated by FHSD Connect AS. To secure stable operation, fund product development, and provide high-quality support, we are introducing a new subscription model." The company says the subscription fee would allow it to provide customers "better functionality, more security, and higher value in the solution you have already invested in."

A second, far more recent data breach at women's dating safety app Tea has exposed over a million sensitive user messages -- including discussions about abortions, infidelity, and shared contact info. This vulnerability not only compromised private conversations but also made it easy to unmask anonymous users. 404 Media reports: Despite Tea's initial statement that "the incident involved a legacy data storage system containing information from over two years ago," the second issue impacting a separate database is much more recent, affecting messages up until last week, according to the researcher's findings that 404 Media verified. The researcher said they also found the ability to send a push notification to all of Tea's users. It's hard to overstate how sensitive this data is and how it could put Tea's users at risk if it fell into the wrong hands. When signing up, Tea encourages users to choose an anonymous screenname, but it was trivial for 404 Media to find the real world identities of some users given the nature of their messages, which Tea has led them to believe were private. Users could be easily found via their social media handles, phone numbers, and real names that they shared in these chats. These conversations also frequently make damning accusations against people who are also named in the private messages and in some cases are easy to identify. It is unclear who else may have discovered the security issue and downloaded any data from the more recent database. Members of 4chan found the first exposed database last week and made tens of thousands of images of Tea users available for download. Tea told 404 Media it has contacted law enforcement. [...] This new data exposure is due to any Tea user being able to use their own API key to access a more recent database of user data, Rahjerdi said. The researcher says that this issue existed until late last week. That exposure included a mass of Tea users' private messages. In some cases, the women exchange phone numbers so they can continue the conversation off platform. The first breach was due to an exposed instance of app development platform Firebase, and impacted tens of thousands of selfie and driver license images. At the time, Tea said in a statement "there is no evidence to suggest that current or additional user data was affected." The second database includes a data field called "sent_at," with many of those messages being marked as recent as last week.
