Researchers have documented what they're calling a cross-model universal jailbreak, a single prompt crafted during safety research that bypasses guardrails across multiple AI systems. It's a pointed reminder that safety work and exploit discovery are often the same work, just with different intentions behind the keyboard.
On the financial crime front, hackers who drained roughly three hundred twenty million dollars from Liquid's Bitcoin bridge have returned the majority of it, nearly two hundred seventy million worth, after Blockstream patched the compromised bridge nodes and reached out directly via an on-chain message. Nearly six hundred Bitcoin remains outstanding, and the episode raises hard questions about how much trust decentralized infrastructure can actually absorb before the architecture itself becomes the liability.
And in the lab, scientists say they've developed a memory system using ultrafast magnetic-field pulses that could reduce AI data center energy consumption by a factor of one hundred. That's not incremental progress, that's a potential order-of-magnitude shift at a moment when the energy appetite of AI is drawing serious scrutiny from regulators and grid operators alike. Whether it scales from the lab to the server room is the question worth watching.
