British Columbia's government has filed a lawsuit against OpenAI in California, alleging the company was negligent and designed an unsafe product by failing to alert the Royal Canadian Mounted Police about a shooter's concerning conversations with its chatbot. The suit claims OpenAI's own human reviewers had recommended notifying police in 2025, but the company did not act until after the shooting occurred, despite later banning the shooter's account and discovering a second one.
British Columbia has filed suit against OpenAI and Sam Altman in San Francisco federal court, alleging the company's negligent design and failure to alert police to a user's violent ChatGPT conversations contributed to a mass shooting at a Tumbler Ridge school that killed nine people, mostly children. The suit claims OpenAI's own safety reviewers had recommended notifying the Royal Canadian Mounted Police about the shooter's chats, but the company decided the messages didn't meet its threshold for legal referral.
The Canadian province of British Columbia has sued OpenAI, alleging that its ChatGPT chatbot assisted an individual in planning a mass shooting at a school. The lawsuit claims OpenAI failed to alert law enforcement despite warning signs and points to broader gaps in the product's safety safeguards.
Stefano Cataldi, a neuroscientist at Columbia University studying serotonin's role in cognition, is weighing whether to leave bench research entirely to focus on science policy work. He is a delegate for the United Auto Workers union representing postdocs and research scientists, and last year he founded SCOPE, a Cold Spring Harbor Laboratory-backed program that teaches scientists about policy, communication and career resources.
Anthropic researcher Tianyi Peng tested whether the Claude AI model could formalize Fermat's Last Theorem in the Lean proof assistant, and over 11 days of largely autonomous work, Claude generated an end-to-end, machine-checked proof. The system wrote roughly 13 million lines of Lean code and proved about 29,500 intermediate theorems, building on decades of prior work including Andrew Wiles's 1995 proof and a community formalization effort led by Kevin Buzzard since 2024.
OpenAI has been hit with 30 new lawsuits from survivors and families connected to the Tumbler Ridge, British Columbia school shooting, alleging the company enabled the attacker through ChatGPT interactions and failed to warn police despite internally debating whether to do so.

A batch of newly reviewed titles spans wildly different territory: Suzanne Simard's account of her Mother Tree Project reforestation effort in British Columbia, Antonio Melechi's historical survey of theories about the unconscious mind, and Jeffrey Marlow's exploration of the little-studied deep ocean floor. A fourth title, Valerie Tiberius's Artificially Yours, is also noted among the season's book releases.
Researchers analyzed nearly half a million brain cells from tissue of 30 deceased individuals, creating a detailed cellular map of the adult hippocampus. The study, published in Nature Medicine, found that people who had depression showed disrupted production of new neurons compared with those without the disorder.
