Great piece. Wonder how eDNA can be used in other contexts.

Chewing burns more calories than you think—and may have shaped our evolution | Science | AAAS

August 28, 2022 Great article! Wondered about the implications of chewing for weight loss: Perhaps humans so readily “overeat” because they don’t have to spend so much time chewing.

COVID antiviral pills: what scientists still want to know

December 18, 2021

Molnupiravir acts by introducing mutations into the viral genome during viral replication. A metabolite of the drug is picked up by a viral enzyme called RNA-dependent RNA polymerase and incorporated into the viral genome, eventually causing so many errors that the virus can no longer survive.

Paxlovid acts by inhibiting an enzyme that’s needed to process some viral proteins into their final, functional form. But the drug is a combination of an antiviral and another drug, called ritonavir, which helps to prevent enzymes in the liver from breaking down the antiviral before it has a chance to disable the coronavirus. Ritonavir, a component of some HIV treatment cocktails, can affect how some other medications are metabolized by the body.

January 31, 2021

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. “}}
