Lower vitamin C levels were linked to reduced brain volume and weaker neural connectivity in older adults, suggesting a potential connection between nutrition and brain health. Could a common vitamin help preserve the brain as we age? A new study of more than 2,000 older adults in Japan found that people with lower levels of [...]

Just as last week was ending, the US government forced Anthropic to pull its two newest models, Fable 5 and Mythos 5, citing national security concerns after Amazon researchers allegedly found a way to bypass Fable 5’s guardrails.  Cybersecurity researchers have since signed an open letter calling the move dangerous, and Anthropic itself noted the same jailbreaks exist in other models. So is […]

Android Developer Verification Timeline Google built Android as the open alternative to Apple almost twenty years ago. Now

The iOS app version of ChatGPT has a great hidden feature for choosing how intelligent you want your answer to be.

Apple is allowing iPhone developers in Brazil to distribute apps through authorized alternative marketplaces and use third-party payment systems following action by the country's competition regulator. "In other words, developers in Brazil will be able to circumvent the App Store and Apple's in-app purchase system, but there are still fees," reports MacRumors. Apple will collect commissions ranging from 5% on externally distributed apps to as much as 26% for some App Store transactions using its payment system. From the report: Alternative app marketplaces will have to be authorized by Apple and will need to meet ongoing requirements. For apps that are still distributed through the App Store, developers will be able to include an alternative payment processing method in their app and/or link users to a website to complete a transaction. These changes are available on iOS 26.5 and later, and they are the result of regulatory action from Brazil's competition regulator. Apple has added a new page on its website with additional details for developers in Brazil. Apple said these changes introduce privacy and security risks for users, including children. The company has introduced safeguards to mitigate these risks, including a notarization process for iOS apps, an authorization process for app marketplaces, and limitations on external links and alternative payments for users under the age of 18. Apple has already allowed alternative app stores and/or third-party payment systems on iOS in the EU, Japan, and South Korea, and it will likely be forced to do so in the UK and Australia too, due to similar regulations in those countries.

Russian cosmonaut Aleksandr Samokutyaev, who served twice as a crew member aboard the International Space Station (ISS), including during the final US space shuttle mission in 2011, has died at the age of 56.

With Samokutyaev's death on Wednesday, he becomes the first former ISS long-duration resident to die in the 26 years that the space station has been a home to 155 other cosmonauts and astronauts as expedition crew members. The cause of his death is unknown.
