Using an EV equipped with laser-based systems dubbed the "Princeton Atmospheric Chemistry Experiment" (PACE), Princeton scientists traversed around the country and found that wastewater plants emit about twice as much greenhouse gas as previously estimated.
Princeton Engineering - Wastewater plants produce twice as much greenhouse gas as estimated
Researchers measured greenhouse gases from 96 wastewater plants across the country and found the emissions were much higher than estimated

Princeton's @uofer.bsky.social has led 14 groups from across the political aisle to approve a shared set of principles for bipartisan criminal justice reform in America.

The groups are now laying plans to convene at Princeton this academic year to flesh out policy proposals.

One year ago, the team at FlyWire led by Princeton's Mala Murthy and @sebastianseung.bsky.social published the first-ever complete connectome of an adult female fruit fly brain.

@thetransmitter.bsky.social talks with scientists about how they're using FlyWire's data to make their own discoveries.

It took decades for the work of Mary Brunkow, Fred Ramsdell, and Shimon Sakaguchi—the winners of this year's Nobel Prize in Medicine or Physiology—to have clinical relevance. That and more of the best in @science.org and science in this edition of #ScienceAdviser: www.science.org/content/arti... 🧪
Continued support for blue-sky research is essential to fuel the breakthroughs of tomorrow.
