🌍 The “Big One” may not come alone: Cascadia and San Andreas can strike together For decades, the nightmare scenario on the U.S. West Coast was “the Big One” — a massive Cascadia megathrust earthquake. But [research](https://news.oregonstate.edu/news/twin-threat-cascadia-and-san-andreas-faults-may-be-seismically-linked) from Oregon State University suggests something even more dangerous: the Cascadia subduction zone and the northern San Andreas Fault may be partially synchronized — meaning one

☣️** "A wake-up call": scientists got AI chatbots to design biological weapons — and the bots delivered** Researchers asked leading large language models for instructions to synthesize deadly pathogens and unleash them in public. Without any jailbreaks or tricks, the chatbots produced detailed, actionable attack plans. The transcripts were shared with The New York Times. 🔹 Over a year ago, 90+ top scientists — including Nobel laureates — signed a letter warning that AI could enable the creatio

**💊 A simple amino acid may slow Alzheimer’s — and it’s already widely available** Researchers in Japan report that arginine, a common and inexpensive amino acid, can significantly reduce toxic protein buildup in the brain and suppress inflammation — two core drivers of Alzheimer’s disease. 🔹 Arginine inhibits the aggregation of Aβ42, the most toxic form of amyloid-beta, with stronger effects at higher concentrations. 🔹 The study used two animal models: fruit flies engineered with the Arctic

**13 kg of Mars got stuck to Curiosity’s drill — and NASA spent 6 days getting it off** While drilling a rock called “Atacama,” NASA’s Curiosity rover accidentally lifted the entire 13 kg sandstone slab attached to its drill — something that had never happened in the rover’s 14-year mission. The rock was too heavy and unstable for the robotic arm to safely move. Engineers tried vibrations and arm repositioning, but nothing worked. On April 29, the team finally freed it by combining drill rota
