Why are evidently tolerating some Covid risk by allowing limited indoor dining in some places. Why isn’t carefully/partly reopening schools a higher priority?

"The search for perfect evidence may be the enemy of good policy,” Greenhalgh, a physician and expert at the Univ. of Oxford. “As with parachutes for jumping out of airplanes, it is time to act without waiting for randomized controlled trial evidence” sciencemag.org/news/2020/10/a…

You're Invited to Virtual EYU 2020 , UCLA's largest annual science outreach event! Sunday Nov. 1st 2020. Free admission for all, grab your tickets today: hopin.to/events/eyu?ref… #scienceeducation #STEM #science #teachers #k12 #UCLA

The WHO just set the PM2.5 annual guideline to 5 ug/m3! Does anyone know how much of the US is above that guideline?

#MyOAarticle the journal would like us to tweet about our recent paper: Ascorbate oxidation by iron, copper and reactive oxygen species: review, model development, and derivation of key rate constants received 8,509 downloads since its publication! nature.com/articles/s4159…

Delighted to see our new paper published in Environmental Science & Technology Journals 🎉 This work explores the chemical mechanisms of an exciting light-driven reaction between Fe(II) and peracids as a potentially unrealised source of OH in cloudwater. pubs.acs.org/doi/10.1021/ac…

(5) In addition to this reactions potential importance in cloud water chemistry, Fe(II)-PAA is emerging as a new and powerful oxidant for wastewater treatment. This study provides new mechanistic information that may also be of importance to the wastewater treatment community.

(6) Special thanks to the collaborative team I worked with during my time at UCLA who brought this all togeher: Chris La, Qinyang Zhou, Jason Le, Jennyfer Galvez-Reyes, Cat Banch, Ken Hook, and Suzanne Paulson
