💊 This one vitamin may help protect your brain from dementia years later

Higher levels of vitamin D in the blood during middle age may be tied to lower amounts of tau protein in the brain years later, according to a study published in Neurology Open Access, an official journal of the American Academy of Neurology. Tau is a key biomarker associated with dementia.

The study followed 793 adults, with an average age of 39, who did not have dementia at baseline. These results suggests that higher vitamin D levels in midlife may offer protection against developing these tau deposits in the brain and that low vitamin D levels could potentially be a risk factor that could be modified and treated to reduce the risk of dementia.

🇨🇺Cuba frees over 2,000 inmates as energy strains weigh on island

Cuba’s government authorized the release of 2,010 prisoners in a sweeping pardon, a move that comes as the island begins to see some relief from a crippling energy blockade. It's the second time this year its communist-run government has announced a prisoner amnesty amid talks with the administration of U.S. President Donald Trump. Cuba's state-run Granma newspaper called the measure a "humanitarian and sovereign gesture."

The decision applies to inmates who have demonstrated good conduct, served significant portions of their sentences, or face chronic health issues. Those eligible include women, young people, and seniors over 60, as well as foreign nationals and Cuban citizens residing abroad.

🪙 Coinbase’s AI payments system joins Linux Foundation, gathers support from Google, Stripe, AWS and others 🤝

Coinbase's AI-focused payment protocol x402 is moving toward becoming an open, standardized infrastructure under the Linux Foundation, the non-profit hub for open-source software development. The open-source consortium also includes initial intent and support being expressed by the likes of Amazon Web Services, American Express, Ant International, Visa and Microsoft.

The protocol has formed an initial governing body, the x402 Foundation, that includes internet services firm Cloudflare and payments giant Stripe. x402 can handle transactions worth only fractions of a cent at high frequency — something traditional credit card networks struggle to manage. The move aims to create a community-governed ecosystem for high-frequency, micro transactions that legacy finance can’t efficiently handle.

🤑 Stellar supports the Machine Payments Protocol

Stellar now supports the Machine Payments Protocol (MPP), the open standard by Stripe and Tempo that lets AI agents pay for services over HTTP. The MPP SDK handles any stablecoin on Stellar with server-sponsored fees so agents never need gas tokens.

The MPP is an open protocol that enables programmatic, per-request payments over HTTP, designed especially for AI agents and APIs. It extends the 402 Payment Required HTTP status code into a machine-readable payment negotiation layer for both humans and autonomous agents.

On Stellar, MPP works with Soroban SAC (Stellar Asset Contract) token transfers so that clients can pay for API requests natively, without an external facilitator. This makes it ideal for micropayments, AI agent-driven APIs, and payment-enabled applications.

⚖️ Ten Foreign Nationals Charged In An International Operation Targeting Cryptocurrency Market Manipulation

Federal grand juries indicted 10 executives and employees of Gotbit, Vortex, Antier, and Contrarian for orchestrating fraud schemes to artificially inflate the trading volume and price of cryptocurrencies. Three defendants, including two chief executive officers, were arrested and extradited from Singapore and made their initial appearance in federal court in Oakland.

These so-called pump-and-dump schemes caused losses to investors in the U.S. and elsewhere. More than $1 million in cryptocurrency has been seized to date. The indictments and arrests were the result of an undercover operation by FBI and IRS-CI targeting illicit “wash trading” in the cryptocurrency industry.

🇸🇦 The anonymous social app that thinks it can work in Saudi Arabia

Fizz, an anonymous social app that started on college campuses, is going global in more ways than one.

“We’ve always known that our big goal is to be a generational social product, rather than a college social app, and now we’re finally executing on it,” — Solomon said.

When Fizz quietly debuted in Saudi Arabia in the middle of March, founder and CEO Teddy Solomon wasn’t expecting the app to catch on like it did. Within 48 hours, the app hit number one overall on the App Store charts; it remains number one in the news category. Fizz users have sent more than one million messages in the past week.

🇮🇪 Ireland tests digital ID to verify age of social media users

Ireland has begun the pilot phase of its national digital wallet, a Government-issued app that can verify a user’s age online without sharing personal details such as a date of birth with third-party platforms. The digital ID will be able to facilitate age verification to help protect children and young people from harms on social media platforms.

The Irish government is required under the EU’s eIDAS 2.0 regulation to make a digital wallet available to citizens by the end of 2026. Banks and credit institutions will be required to accept it for identity verification a year later, and private companies including social media platforms could begin using it by the end of 2027.

🤖 Researchers build Wi-Fi chip that can operate inside a nuclear reactor

A team of researchers from the Institute of Science Tokyo unveiled a hardened wireless receiver that can withstand prolonged exposure to radiation. This chip was primarily designed to allow robots to work in contaminated areas for decommissioning nuclear reactors.

After the 2011 nuclear disaster at the Fukushima Daiichi plant, engineers began using robots to help characterize and clean up the site. The need for such robots is only growing. The receiver endured a total radiation dose of 500 kilograys, orders of magnitude higher than the doses typically tolerated by electronics in outer space.
