The Download: GLP-1 and eating disorders, self-aware cities, and forever chemicals

Eating disorders are on the rise. GLP-1s could make things worse.

GLP-1 weight-loss drugs are one of the biggest biotech breakthroughs of the last decade. But to some clinicians, they can represent something sinister—a potential trigger for eating disorders.

A new report suggests the global incidence of anorexia nervosa and bulimia nervosa shot up by 71% between 1990 and 2023. And clinicians are already seeing GLP-1s exacerbate the issue.

Here’s how they could make an already growing problem worse .

—“Love is Infrastructure” is a short fictional story by Charlie Jane Anders, author of a forthcoming novel titled Good Things Are Coming Your Way .

Mainspring and St. Barnabas are two neighboring cities with different personalities. They’ve never particularly liked each other, but that changes when both develop minds of their own, shaped by the votes of their residents.

As the cities begin to fall for each other, a third city enters the picture. Turnbull promises Mainspring a more efficient future, but its vision of urban life comes with a troubling price.

Used for decades in everything from nonstick pans to firefighting foams, PFAS, or “forever chemicals,” are linked to increased risks of fertility challenges, developmental delays, cancer, and reduced immune response.

Scrubbing PFAS-contaminated soil could eliminate a list of woes for people and planet. The concept is still in its infancy, but we can limit their buildup by pulling the chemicals out of water systems.

Find out how close we are to ridding the world of forever chemicals .

Quote of the day

—Steven Strogatz, a mathematics professor at Cornell University, tells Business Insider that personal appeal will become more valuable as AI increasingly takes over intellectual work.

One more thing

In early February, animal welfare advocates and AI researchers arrived in stocking feet at Mox, a shoes-free coworking space in San Francisco. They gathered to discuss a provocative idea: if artificial general intelligence is on the horizon, could it prevent animal suffering?

Some brainstormed using custom agents in advocacy work, while others pitched cultivating meat with AI tools. But the real talk of the event was a flood of funding they expect will soon flow to animal welfare charities, not from individual megadonors, but from AI lab employees.

Some attendees also probed an even more controversial idea: AI may develop the capacity to suffer, which could constitute a moral catastrophe. We investigated why their ideas are gaining momentum—and sparking controversy.
