As Chinese open-weight AI models grow in capability and popularity, arguments about what should be done about them have once again reached a fever pitch.
There’s talk that the Trump administration might try to ban them (though it hasn’t yet acted on the idea). Meanwhile, proprietary model makers, particularly OpenAI and Anthropic, appear increasingly concerned about them.
Substack has launched a new feature that can show you which of your favorite newsletters are being written using AI.
This week, the newsletter and writing platform announced an integration with the AI writing detection software Pangram that will allow users to scan posts, comments, and replies on Substack’s app to see an estimate of how much of the content was written by a human and how much was AI.

From microplastics clogging up our oceans to landfills leaching dangerous chemicals, plastic waste is a serious and growing problem for human health and the environment. We need to recycle more and, crucially, recycle better.
OpenAI announced Wednesday that it will spend $750 billion on infrastructure through 2030, some 25% more than it estimated earlier this year, The Wall Street Journal reported. The renewed blitz comes as its Stargate data center project appears to have stalled.
The musician spoke with three figures at the global legal advocacy organization to discuss midwifery, abortion access, and the maternal health crisis
Olivia Rodrigo partnered with the Center for Reproductive Rights to dispel misinformation around midwifery, abortion bans, and the maternal health crisis. In a series of interviews, the musician spoke with three figures at the global legal advocacy organization, including an associate director of litigation and two senior attorneys, about what people often get wrong about the fight for abortion access.
YouTube is attracting more professionally produced episodic entertainment from talent-founded production companies, and global brands are turning to the platform to develop original series for digital audiences.
Comparison of total drag coefficient (CD) versus Reynolds number for a smooth surface (Plain) and DMR-coated surfaces (DMR1, DMR2). DMR achieves up to 43.6% drag reduction in the transitional regime and maintains lower drag than the smooth surface up to the highest tested Reynolds number. Credit: Yakeno et al.
Logically, you would think a sleek surface has optimal aerodynamics—but recent research at Tohoku University turns this fundamental principle on its head. Applying an irregular microscale surface texture reduced the aerodynamic drag of a test model. The innovation has potential applications in the design of fuel-efficient vehicles. The study is published in the Journal of Fluid Mechanics.
