the download: fossil fuels and new endometriosis tests

This edition of The Download highlights how this year’s UN climate talks again omitted the phrase "fossil fuels" and why new noninvasive tests could shorten the nearly 10 years it now takes to diagnose endometriosis.

This edition of The Download rounds up technology and science stories from MIT Technology Review, led by a climate dispatch from Belem, Brazil. Attendees at this year’s UN climate talks faced oppressive heat, flooding and a fire that delayed negotiations. Despite urgency from some delegates and the president of Brazil framing the conference as one of action, the final draft agreement did not include the phrase “fossil fuels.” The item’s author, Casey Crownhart, questions why formal recognition of the primary drivers of emissions remains so difficult even as emissions and global temperatures reach record highs.

Health coverage in this issue spotlights a surge in noninvasive diagnostics for endometriosis. The condition causes debilitating pain and heavy bleeding in more than 11% of reproductive-­age women in the United States and typically takes nearly 10 years to diagnose, in part because roughly half of cases do not appear on scans and surgery is required to obtain tissue. Colleen de Bellefonds reports that a new generation of tests could accelerate diagnosis and improve management, with the story drawn from the last print issue of MIT Technology Review magazine.

The newsletter’s must-reads and features cover a range of technology topics. Headlines include OpenAI’s claim that a teenager circumvented safety features and the company’s subsequent refutation of liability in the 16-year old’s death, debate over public-health appointments at the CDC, and a study suggesting Artificial Intelligence could already replace 12% of the US workforce. A cultural piece traces roots of modern Artificial Intelligence to B.F. Skinner’s pigeon experiments and behaviorist ideas. The issue also notes a quote from Pope Leo XIV cautioning against overreliance on Artificial Intelligence and a lighter section of links and curiosities under the banner “we can still have nice things.”

U.S. senators propose broader chip tool export ban for Chinese firms

A bipartisan proposal in the U.S. Senate would shift semiconductor equipment controls from specific fabs to targeted Chinese companies and their affiliates. The measure is aimed at cutting off access to advanced lithography and other wafer fabrication tools for firms such as Huawei, SMIC, YMTC, CXMT, and Hua Hong.

Trump executive order targets state Artificial Intelligence laws

Executive Order 14365 lays out a federal strategy to discourage, challenge, and potentially preempt state Artificial Intelligence laws viewed as burdensome. Employers are advised to keep complying with current state and local rules while preparing for regulatory uncertainty in 2026.

Who decides how America uses Artificial Intelligence in war

Stanford experts are divided over how the United States should govern Artificial Intelligence in defense, surveillance, and warfare. Their views converge on one point: decisions with such high stakes cannot be left to companies alone.

GPUBreach bypasses IOMMU on GDDR6-based NVIDIA GPUs

Researchers from the University of Toronto describe GPUBreach, a rowhammer attack against GDDR6-based NVIDIA GPUs that can bypass IOMMU protections. The technique enables CPU-side privilege escalation by abusing trusted GPU driver behavior on the host system.
