🇺🇸 The CIA used a futuristic new tool called “Ghost Murmur” to find and rescue the second American airman who was shot down in southern Iran

The secret technology uses long-range quantum magnetometry to find the electromagnetic fingerprint of a human heartbeat and pairs the data with AI software to isolate the signature from background noise. It was the tool’s first use in the field by the spy agency — and was alluded by President Trump and CIA Director John Ratcliffe at a White House briefing.

“The name is deliberate,” — one source said. “‘Murmur’ is a clinical term for a heart rhythm. ‘Ghost’ refers to finding someone who, for all practical purposes, has disappeared.”

🧑‍⚖️ Massachusetts House passes bill to ban kids from social media

The Massachusetts House of Representatives voted 129-25 to pass legislation that would ban all kids under age 14 from using social media in the state. The ban would impact all kids under age 14. Kids ages 14 and 15 would need parental consent to use social media.

The bill also calls for a statewide ban on cellphones in schools, which was passed by the Senate last summer. The Attorney General's office is tasked with implementing the social media ban starting October 1, 2026.

🤑 Bitcoin gets its first working prototype of quantum-resistant wallet rescue tool

A top Bitcoin developer has built something the community has debated for years but never actually produced: a way to rescue ordinary wallets if the network is ever forced to defend itself against a quantum computer.

Olaoluwa "Roasbeef" Osuntokun, chief technology officer at Lightning Labs, unveiled the working prototype to the Bitcoin developer mailing list. The tool targets a specific and uncomfortable flaw in Bitcoin's long-term defense plan, a widely discussed "emergency brake" upgrade designed to protect the network from quantum attacks could also lock millions of users out of their own funds. Osuntokun's proposal is an escape hatch.

The system would let users of vulnerable Taproot and other modern wallets prove they created a wallet using its secret seed, without revealing that seed, providing a backup way to access funds if traditional digital signatures are disabled.

The prototype is already functional. Running on a high-end consumer MacBook, generating the proof took about 55 seconds, while verification took under two seconds. The resulting proof file was roughly 1.7 MB, about the size of a high-resolution image.

Osuntokun said the system was built as a side project and remains unoptimized. But the prototype closes a gap that had lingered in theory: how to protect Bitcoin from a future threat without the collateral damage of locking users out of their wallets.

⚡️ NATO chief says group moving on from unhealthy co-dependence on US

"Europe is assuming a greater and fairer share of the task of providing for its conventional defense, and from that there will be no going back, nor should there be. This is a move from unhealthy codependence to a transatlantic alliance grounded in true partnership," — Mark Rutte said.

🚀 This founder helped build SpaceX’s most powerful rocket engine. Now he’s building a ‘fighter jet for orbit.’

Jeff Thornburg helped turn a government research project into SpaceX’s most powerful rocket engine. Now, he’s trying to do the same thing at his startup Portal Space Systems, which is taking an idea set aside by NASA and turning it into high-powered propulsion for the next generation of spacecraft.

The company is developing a technology called solar thermal propulsion. Today’s standard satellite engines either burn chemical fuel or convert the sun’s energy to electricity, using that to power efficient but low-powered thrusters. Portal’s engines would instead concentrate the heat of the sun, using that to heat propellant and move the spacecraft along at high speed.

The technology has been the subject of investigation in government research labs since the 1960s, most recently as a concept for sending a probe into interstellar space, but has yet to make it into orbit. Thornburg, along with co-founders Ian Vorbach and Prashaanth Ravindran, plans to change that in the next two years.

⚡️🇮🇷 Iran’s sanctions-busting crypto ambitions grow on toll payments

Tehran has signaled that payments in digital currency should form part of any toll system for vessels passing through the Strait of Hormuz — tokens cannot be easily confiscated under sanctions.

“There are reports that Iran is charging fees to tankers going through the Hormuz Strait,” — Donald Trump warned Iran against charging tolls on vessels. “They better not be and, if they are, they better stop now!”

📱 Instagram expands its restrictions for teens internationally and introduced a small but useful update

Instagram is expanding its revamped Teen Accounts, inspired by 13+ movie ratings criteria and parent feedback — teens will see content on Instagram that’s similar to what they’d see in an age-appropriate movie by default. There's also a new setting called “Limited Content” that has stricter content filters. The company would show less content with themes like extreme violence, sexual nudity, and graphic drug use.

Users now have the option to edit comments, which is a long-awaited fix for anyone who’s ever had to delete and re-post a comment just to fix a typo. But there's only 15-minute window after posting to make changes.

🤑 Is Blockchain Privacy a Trade-off? Scaling Confidential Payments on Stellar

The biggest challenge for institutions moving to blockchain isn't efficiency — it's privacy. How do you leverage a public ledger without exposing client data or competitive strategies to the world? 🤔

In this episode Denelle Dixon and the Stellar Development Foundation’s Chief Product Officer, Tomer Weller, unpack the team’s strategy for configurable privacy.🔐⚙️

They explore why privacy and openness don’t have to be a trade-off and dive into the cutting-edge technology making private institutional payments a reality in 2026, including:

➠ Confidential Tokens vs. Privacy Pools: Understanding the different cryptographic models for securing balances and transactions.
➠ The Power of Zero-Knowledge (ZK): How ZK proofs allow for verifiable computation without revealing sensitive underlying data.
➠ A "Menu" of Compliance: How configurable privacy provides institutions with the administrative controls needed to satisfy regulators.
➠ Live Tools on Stellar: A look at the new building blocks and partnerships (like Nethermind and OpenZeppelin) that are already open-sourcing privacy solutions on the network.
