Deep dive into the surge in US pedestrian deaths:

"It’s not that more pedestrians are getting hit by vehicles; it’s that the ones that are getting hit are more likely to die."

"[That] seems like fairly strong evidence for the theory that the rise in large SUVs is behind the uptick in ped deaths."

Why Are So Many Pedestrians Killed by Cars in the US?

It’s unfortunately not uncommon for pedestrians to be killed by cars in the US.

Sometimes science is field work, sometimes it is lab work, computer work, discussions, presentations... and sometimes it is executing plan B and driving a highly sensitive and sophisticated scientific instrument across four countries and over 1500 kilometers!

This no-fuss, one-pot recipe is inspired by avgolemono soup, a traditional Greek rice soup that is prized for its silky texture and bright flavor, thanks to egg yolks and an invigorating dose of lemon.

Avgolemono Chicken Soup With Gnocchi Recipe

This no-fuss, one-pot recipe is inspired by avgolemono soup, a traditional Greek rice soup that is prized for its silky texture and bright flavor, thanks to egg yolks and an invigorating dose of lemon This soup achieves similar results while replacing the rice with store-bought gnocchi for a heartier take and a texture boost The approach is simple: Simmer rotisserie chicken with stock, lemon zest and gnocchi, then thicken the soup with egg yolks and lemon juice

Pretty good but …. Why with approximately the same amount of co2 is Mars so cold? Because Mars has little N2 or O2. Although N2 and O2 only weakly interact with IR radiation, their collisions with H2O, CO2, CH4, and N2O are essential for making these small molecules good greenhouse gases.

So in fresh smoke the ozone gets titrated out by all the VOCs but its more complicated as the smoke moves and ages- this paper is a great look into the chemistry! www.science.org/doi/full/10....

Ozone chemistry in western U.S. wildfire plumes

While ozone increases rapidly in wildfire plumes, downwind its production rate slows dramatically as nitrogen oxide levels decline.

How much does the DC power influence the battery design (not including wires and inverters)? Eg, what’s the difference between a 100MW / 2 hour BESS and a 25MW / 8 hour battery?

Rick arrived in 1975 intending to study combustion chemistry and ended up playing an enormously influential role in developing new instrumentation to quantify atmospheric aerosol and helping to mitigate air pollution in LA and beyond.
