The report offers a surfeit of evidence to suggest that students who use generative AI are already seeing declines in content knowledge, critical thinking and even creativity. And this could have enormous consequences if these young people grow into adults without learning to think critically. 🍎🎢
The risks of AI in schools outweigh the benefits, report says
A new report warns that AI poses a serious threat to children's cognitive development and emotional well-being.

Landscape? This was a photo I captured of caffeine crystals several years ago. I foresee a lot more of this molecule in my life in 2026. #polarizedlight #microscopy #sciart #caffeine

As 2025 draws to a close, some images that summarize my holiday preoccupations. First up, cholesterol crystals by polarized microscopy. Healthy eating was not a priority these last weeks of the year. #microscopy #crystals #polarizedlight #sciart #ochem

Trump quietly shutters the only federal agency that investigates industrial chemical explosions.
Hazardous chemical accidents happen in the U.S. about every other day. Who will investigate them now?

This is so stupid.
FDA announcement it will begin the process of pulling prescription fluoride drops and tablets for children off the market. The supplements are usually given to kids at high risk for cavities.

Fluoride drops and tablets for kids should be taken off the market, FDA says
Despite decades of evidence that fluoride prevents cavities, the agency said the best way to keep kids' teeth strong is to stop eating so much sugar.
