Welp, there it is. The CDC is now officially manipulating data and their count of measles deaths in 2026 now stands at ZERO. My understanding of reportable diseases is that the CDC would usually use a state health department’s determination as the final say. The new CDC Director is failing us.

The CDC left two measles-associated Pa. deaths out of its latest count after RFK Jr. sparred with Gov. Shapiro
HHS Secretary Robert F. Kennedy Jr. has accused Pennsylvania of not cooperating with the CDC in its handling of a measles outbreak.

This work was carried out by my Ph.D. student, Darshi T. Hewa Edirappulige, with help from my postdoc Pedro J. Castro. The photo shows Darshi with her ACS PHYS poster award from 2025. Darshi will defend her thesis next month. Anyone looking for a sharp computational chemist? 6/6

Our conclusion: The reported loss of Hg(0) is best explained by surface-reactions, not a gas-phase reaction. The gas-phase Hg(0)+O₃ reaction appears irrelevant in the laboratory and in the atmosphere. Interested in your feedback! DOI: 10.1021/acs.jpca.6c02693 5/6

The other hypothesized product was OHgOO. Production of this diradicaloid from Hg(0) + O3 is endothermic by > 21 kcal/mole. Given this, a gas-phase reaction would have an observed rate at least 10 billion times lower than reported. 4/6

To test the possibility of a direct Hg(0) + O3 reaction, we used high-level quantum chemistry to examine two hypothesized reaction products. One was a cyclic HgO3, which collapses to a Hg–O₃ van der Waals complex. This is unstable and does not lead to a chemical reaction. 3/6

Some modelers insisted they needed one-step oxidation by OH and/or O3 to match field observations. Three years ago we showed that O3 and OH, together, can oxidize Hg(0) in two steps (DOI: 10.1021/acs.jpca.2c04364). But this doesn’t rule out a direct Hg(0) + O3 reaction! 2/6
Text “Two-step reaction mechanism” followed on subsequent line by the reaction OH + Hg reversibly forming HOHg radical. The next line has the reaction of HOHg radical with ozone to form HOHgO and molecular oxygen.Two graphs next to each other, one labeled March 4, 2010 and the other labeled July 1, 2010. The x-axes are labeled “Fraction HOHg radical making Hg(II)” and run from zero to one. The y-axes are labeled altitude and run from 0 km to 18 km. Both graphs have black lines labeled “without ozone” and blue lines labeled “with ozone”. Both lines labeled “without ozone” start at 0.2 or below and decay to zero in going from 0 to 2 km and stay low thereafter. The lines marked “with ozone” start at 0.45 or higher and approach 1.0 at 6-8 km.

Many models of atmospheric mercury include a GAS-PHASE Hg(0) + O3 reaction. But the observed products are solids (see image from PCCP 2008, by Pal and Ariya), suggesting reaction on the reactor walls. New paper: 10.1021/acs.jpca.6c02693 🧵 1/6
