MIT Technology Review’s The Download on climate talks, endometriosis tests and AI’s roots

MIT Technology Review published this edition of The Download on November 27, 2025. In its climate section, Casey Crownhart says this year’s UN climate talks in Belém ended with a “watered-down agreement” whose final draft omitted “fossil fuels,” despite record-high emissions and temperatures. She wonders why formally acknowledging the cause of the problem is so difficult. The newsletter also reports that noninvasive endometriosis tests are emerging, potentially helping speed diagnosis and improve management of a condition that can involve debilitating pain and heavy bleeding. It says diagnosis takes nearly 10 years on average, partly because some cases do not appear on scans and surgery is required to obtain tissue samples. In its final feature, the newsletter argues that B.F. Skinner’s pigeon research deserves recognition as a precursor to AI: his account of learning through trial and error influenced computer scientists whose work later provided a foundation for leading AI tools. The climate section leaves open why formal acknowledgment of fossil fuels remains difficult at climate talks; this edition does not answer that question.

attribution — uncertain: This is one newsletter issue with its own commentary, not a bare listing. The climate section is correctly credited to Casey Crownhart. However, the endometriosis item is credited to Colleen de Bellefonds, and the Skinner pigeon argument is a blurb of Ben Crair's story. The reading attributes both to 'the newsletter', which blurs whose argument it is. Smallest repair: name de Bellefonds and Crair, or say the newsletter summarizes their stories.

provided the foundation for many of the leading AI tools. Read the full story. —Ben Crair

summary — pass: The title, summary and question faithfully reflect the three featured items. The question is Crownhart's own. A general reader can follow the actors and developments. One phrase is softened: 'some cases' stands in for the source's 'half the cases'. That is a minor loss of precision, not a distortion. The question is restated in closing without a manufactured answer.

Why is it so hard to formally acknowledge what’s causing the problem?

date — pass: The reading gives November 27, 2025, which matches the UTC calendar day of originalPublished (2025-11-27T13:10Z). The kind is publisher-page, so no archive disclosure is needed. The limitation still notes the later retrieval. 'This year’s' talks is Crownhart's attributed framing. The later Deep Dive sidebar items (for example, OpenAI math findings) are not used or relied on.

support — pass: Each claim is directly supported by the quoted source text. The endometriosis benefit is kept conditional ('could help'), and the Skinner influence claim matches the blurb. No unsupported stakeholder costs or benefits are added.

a new generation of noninvasive tests are emerging that could help accelerate diagnosis and improve management

media — pass: No media is selected, and no verified candidates were supplied, so nothing is misidentified.
