But an increasing proportion of arrests have been made by local law enforcement in partnership with ICE, via 287(g) agreements. In many regions, it can be difficult to know when local officers are conducting routine policework or immigration enforcement. In many cases, they are doing both.

A chart showing immigration arrests by local police, which have increased steadily since ICE's new enforcement strategy began in April 2026, reaching its highest amount above 200 arrests per day in late June 2026.

ICE is now lying in wait outside convenience stores, or at busy intersections. Agents are arresting people at international airports. Local police and sheriffs, deputized by the federal government, are detaining immigrants during traffic stops. ICE is now detaining more immigrants than ever before.

A chart that shows a timeline of ICE immigration enforcement against different significant events (Los Angeles raids, Minneapolis and Chicago raids), with a line in late March 2026 that says "New enforcement strategy begins" before a peak of over 1,500 daily arrests in July 2026.

The result: national govts, think tanks and universities refocusing AI evaluations to focus on highly speculative problems where there is no empirical evidence that they're possible - but lots of ideological reason to take them seriously, whatever the costs of the very REAL issues we then ignore .

Since we’re doing another round of “AI will destroy humanity” doom-hype, it’s a good time to announce a new paper myself and my postdoc advisor just had accepted by BioSocieties on just this. TL;DR: almost all the “AI can make bioweapons” literature comes ultimately from the Effective Altruists.

Notably the journalist who covered it is part of the Tarball Center for AI journalism, funded by by a who’s who of EA/rationalists and AI-tied philanthropy. It’s an industry aligned group, like we used to see with tobacco and still see with fossil fuels. Sucks to see this in science.

8/ As the @nytimes.com reported, DraftKings uses machine learning and data scientists to entice losing customers with promos to keep them going — even if those are the customers at risk of becoming addicts. The company says it doesn’t unfairly target people.

Data science helps determine who receives betting incentives, but the company has resisted using similar technology to protect gamblers at risk of addiction.

FFF – Cailin O’Connor - Closing the Loop on Social Influence in Science

The Center for Philosophy of Science invites you to our Featured Former Fellow online lecture presented by: Featured Former Fellow: Cailin O’Connor Tuesday, September 22nd @ 12:00 pm - 1:30 pm EST Title: Closing the Loop on Social Influence in Science Abstract: The prevalence of social influence in science is widely documented. But this influence is not one-sided. Social beliefs and values shape science, and at the same time are shaped by scientific findings. This mutual influence raises the possibility of dynamical interplay between science and society. But while this possibility has been mentioned numerous times in the literature, there is relatively little work attempting to analyze and outline how this mutual influence might work. This talk argues that two-way influence between science and society is promiscuous, occurring via a wide range of mechanisms that start with both values and related cultural background beliefs, and influence both values and related cultural background beliefs. I’ll discuss three sorts of general patterns at play—positive feedback, polarizing feedback, and amplification. This talk will be available online only: Zoom: https://pitt.zoom.us/j/91092965122 YouTube at https://www.youtube.com/channel/UCrRp47ZMXD7NXO3a9Gyh2sg.

*Big El Niño Boost in next few weeks! Our already record El Niño is about to get a spike to “Historic”. Humans have never seen such an episode, so I’d expect some unprecedented events. A major push of west winds in the Tropical Pacific will surge warming. 1/

Ok, I hate snow and when it's so cold the air hurts my face. But this is not good. This El Niño will occur at a time of already unprecedented ocean warmth globally with the average temp hitting a record high in Aug The impacts are very serious for everybody #Pinks www.ctvnews.ca/climate-and-...

In a strategic retreat in the fight against climate change, the U.N. acknowledges that Earth has lost its chance to prevent some of the worst of global warming’s harms. So now the world must figure out how to get temperatures below the danger zone and back to safety, officials say.

Global warming will exceed limit, U.N. says in a report that maps path to get back below danger zone

“If we act now we can limit overshoot,” the report said. “Not a safe world, but safer than remaining above” 1.5 degrees for the long term.

Majority of Americans support banning social media for kids under 16 Across major demographic & partisan groups, more Americans support a ban. Large majorities of U.S. adults also support parental consent, age verification and time limits. And is even more widespread today than in 2023.

Researching this book was such a fantastic adventure, seeing firsthand land set free across Costa Rica, Scotland, Ireland, and meeting some of the true heroes rewilding the Earth. So what an immense joy to finally get a (*beautiful*) copy into my hands! Releases September 10th.

We obtained 3,000 pages of emails sent by execs asking that their facilities be exempted from Clean Air Act rules. As of mid-July, the White House has approved ~200 requests. Tomorrow at 4 pm ET, join us for an event exploring the impact (w/ @chicagotribune.com @deepsouthtoday.org @latimes.com):

Join us for a discussion about the rollback of the Clean Air Act and what it means for public health in communities across America.
