Five manufacturers—HP, Dell, Lenovo, Acer and Asus—will launch models starting at $899, with pre‑orders open and a year of Google AI Pro included.

Google has launched the $899 "Googlebook," an AI‑focused laptop that runs Android with ChromeOS features and integrates its Gemini AI for tools like an AI‑powered cursor, the Rambler dictation assistant, and AI‑enhanced widgets. Pre‑orders are open, with the device aimed at replacing Chromebooks in schools and enticing consumers with a decade of updates and a year of Google AI Pro services.

Apple’s new CEO John Ternus debuted the company’s first foldable iPhone Duo at his inaugural product launch, signaling a shift toward AI‑driven hardware under his leadership. In an interview, Bloomberg’s top Apple reporter Mark Gurman discusses how the event reflects internal cultural changes and the strategic pivot from the traditional iPhone era to an AI‑focused future.

RAND proposes a "Freedom of Action" strategy for the United States to maintain geopolitical advantage and human agency as AI advances toward superintelligence, outlining four pillars—human‑AI ecosystem, AI‑security architecture, modernized security institutions, and citizen capacity—and seven possible policy archetypes ranging from coexistence to denial. The paper emphasizes flexibility, investment in safety, and preparedness for unknown AI trajectories.

MIT Technology Review and the Times of San Diego produced the first comprehensive map of migrant deaths near US‑Mexico border surveillance towers, drawing on thousands of government documents, public‑record requests and interviews with officials, agents and humanitarian groups. The 15‑month investigation reveals patterns across policies and tower technologies, highlighting gaps in data and the human cost of border surveillance.
