Human Brain Organoids Build Circuits in Cortex-Less Mice — 5dResearchers have transplanted lab-grown human brain organoids into mice engineered to lack most of their cortex, creating xenocortical models in which human tissue integrates and expands to occupy missing brain regions, showing activity and neural connections that can restore aspects of cognition and behavior. These studies establish a new in vivo platform for studying human brain development and neurodevelopmental disorders, while highlighting both therapeutic potential and ongoing challenges in translating organoid-based findings to human health.

Chris Dalton Restoring some mouse behavior is interesting but it probably won't translate cleanly to fixing actual human brain problems anytime soon.

Mantic Raises $25M After Beating Human Forecasters — 4dLondon AI startup Mantic raised $25 million in seed funding led by Radical Ventures, with Microsoft’s M12, after its judgmental forecasting system beat all human forecasters at the Metaculus Cup, signaling strong demand from hedge funds, corporates, and governments for medium-term risk and scenario planning. Founded in 2024 by Toby Shevlane and Ben Day, Mantic blends human-style reasoning with backtested historical data to predict geopolitical, economic, and strategic events, targeting scenarios where traditional models struggle.

Nicole Hardy Beating the top human forecasters on Metaculus shows this approach could help with tricky geopolitical calls that pure models miss.

Remains Found During Grand Canyon Flood Search — 6dNPS rangers recovered human remains Sept. 14 near Crystal Rapid, 10 miles downriver from Phantom Ranch; identity not yet known as Timothy Allen Smith remains missing.

Anthropic researcher says AI has more than 10% chance of 'killing all humans' after colleague quits — Sep 9, 2026

Tom Gallagher Quitting after hearing that warning says more about the company's direction than any public statement could.

AI Leaders Split Over Regulation and Safety — Sep 13, 2026Microsoft CEO Satya Nadella urged that pursuing superintelligence must benefit humanity and remain under human control, advocating deliberate pacing and broad access for both closed and open-source AI models, plus embedded evaluators to turn safety principles into practice. He also stressed that organizations should own their learning loops and proprietary knowledge, cautioning against control by a few entities, and noted Microsoft will publish a Code of Conduct for its MAI models to guide public consultation.

UN Experts Say Belarus Justice System Targets Critics — Sep 15, 2026UN experts’ Sep 15, 2026 report: Belarus justice system systematically represses Lukashenko critics since 2020; some abuses may be crimes against humanity. Belarus did not cooperate.

Derek Foss Without cooperation from Minsk it's hard to see how these abuses can be properly investigated or the victims get any justice.

37 Suspected Miners Die in Niger State Custody After Raids — 4dIn Niger State, the NSCDC’s burst operations against illegal mining led to the detention of scores of suspected miners, with multiple detainees reported dead in custody amid a suspected disease outbreak and their bodies deposited at General Hospital Minna. Authorities say they are investigating, upholding human rights, and urging calm as families demand answers and security tensions persist.

Pig Kidney Bridges Patient to Human TransplantHealth — Sep 5, 2026A patient named Tim Andrews received a genetically engineered pig kidney in January 2025, stayed off dialysis for 271 days, and then transitioned to a human donor kidney, marking the first reported pig-to-human kidney transplant followed by a human transplant. The case, published in The Lancet, supports xenotransplantation as a potential bridge to timely human transplants while highlighting ongoing challenges like immune rejection and long-term viability of pig organs.

France Regrets UN Post Criticizing US Rights Record as Envoy Delayed — Sep 13, 2026France’s UN mission apologized for an online post criticizing the United States’ human-rights vote at the UN General Assembly, and Washington welcomed the statement as it leaves in place the stalled approval of France’s next ambassador to Washington. The dispute concerns a single vote rather than a broader human-rights stance and has delayed the ambassador appointment amid ongoing friction over the UN rights-chief tenure extension vote.

Priya Raman France overreacted with that online criticism and the apology should have cleared the way for their ambassador by now.

Pregnancy Rewires Brain Circuit Driving Food Cravings in Mice — 3dResearchers have pinpointed a brain mechanism in mice linking pregnancy to stronger cravings for palatable foods: serotonin neurons in the dorsal raphe nucleus become less active during gestation due to increased SK3 channel activity, which drives food-seeking behavior. The team also traced a neural pathway to the ventral tegmental area, where activation reduces cravings, shedding light on the neural basis of gestational eating patterns observed in humans.

DHS Watchdog Finds 79 Detainees Held in Cages — Sep 14, 2026DHS OIG found 79 Alligator Alcatraz detainees held in 4-by-4-foot outdoor metal cages and 18-sq-ft enclosures, a practice it called unprecedented and not aligned with humane standards.
