Freelance journalist Gabriel Popkin and host Sarah Crespi discuss what will happen to ash trees in the United States as federal regulators announce dropping quarantine measures meant to control the emerald ash borer—a devastating pest that has killed tens of millions of trees since 2002. Instead of quarantines, the government will use tiny wasps known to kill the invasive beetles in hopes of saving the ash. “}}

Reducing transmission of SARS-CoV-2 | Science
August 9, 2020Illuminating article by @kprather88
https://science.ScienceMag.org/content/368/6498/1422… Has a worrisome conclusion: #SARSCoV2 can be spread as an aerosol by asymptomatic individuals. The virus behaves a bit like 2nd-hand smoke. (Discussed in @ScienceMagazine podcast by @boron110.)
Perhaps being in public w/o a mask will eventually be treated like public smokers.

Interesting paper. Wonder whether this technology could readily track people and thus has #privacy implications…

A stronger, cooler wood
One good way to reduce the amount of cooling a building needs is to make sure it reflects away infrared radiation. Passive radiative cooling materials are engineered to do this extremely well. Li et al. engineered a wood through delignification and re-pressing to create a mechanically strong material that also cools passively. They modeled the cooling savings of their wood for 16 different U.S. cities, which suggested savings between 20 and 50%. Cooling wood would be of particular value in hot and dry climates.
