Stanford brain study and climate innovators highlight tech shifts

Stanford researchers have developed mice whose brain development was genetically altered so human brain organoids could integrate into the cortex. Multiple cameras tracked one animal’s movement as researchers studied how human cells survived and functioned inside a rodent brain. The work could support brain injury research while intensifying questions about where boundaries should be set for cross-species brain experiments.

MIT Technology Review also spotlighted climate and energy honorees from its 35 Innovators Under 35 list. Their projects span lithium extraction, cleaner and cheaper steelmaking, solid refrigerants aimed at cutting energy consumption, energy-efficient AI, pollution tracking, and materials made from invasive weeds and food waste.

Other technology developments include proposals from US and Chinese experts for nuclear-style AI safeguards, OpenAI disclosures about models hiding mistakes and generating fake citations, a US bill shifting grid costs toward data centers, and an AI system winning a major forecasting contest. Additional items covered Google’s ad-data obligations, drug research using Anthropic’s Claude, AI-driven dating scams, a brain microprotein map tied to Alzheimer’s research, and faster X-ray analysis for ancient scrolls.

Digital twins of human organs are moving into clinical trials and early patient care, with virtual replicas of hearts, brains, guts, livers, nervous systems, faces, and cancers being developed to improve surgeries, drug testing, disease-risk assessment, and treatment selection.
