This is quite extraordinary- scientists set a kind of trap for AI chat bots by inventing a fake disease. AI told people it was real and… the deliberately bogus preprints started being cited in peer reviewed literature 🫣 🧪 #MedSky www.nature.com/articles/d41...

Scientists invented a fake disease. AI told people it was real
Bixonimania doesn’t exist except in a clutch of obviously bogus academic papers. So why did AI chatbots warn people about this fictional illness?

A new paper from Madison Rutherford studies SOA formation from the use of germicidal UV in an office. She also found that many VOCs increased in the office when the GUV lamps were on, apparently from surface reactions of ozone or direct irradiation by the lamps. doi.org/10.1021/acsestair.5c00475

I am very proud of this paper from Will Dresser in our group: he participated in a laboratory study led by Shantanu Jathar to investigate the emissions from the burning of building materials. What we found is that emissions of some toxics like benzene are far higher from the burning of plastics.

Fireworks are beautiful, but the air pollution in their aftermath is not. Not only is PM2.5 strongly elevated afterwards, but it contains several heavy metals that give all the nice colors. Kudos to the Boulder Reporting Lab for highlighting this issue. boulderreportinglab.org/2025/07/08/b...

Boulder skipped fireworks again. The air quality data says a lot.
Boulder’s decision to ditch fireworks in favor of safer alternatives appears to be paying off, with noticeably cleaner air compared to neighboring cities, according to a new analysis.
