Thanksgiving 2020

This morning from my deck: these plants still have their brilliantly red leaves. I believe this is because their chlorophyll pigment is no longer present–it would have absorbed red and reflected back green. The chlorophyll has been replaced by a new pigment: anthocyanin–which reflects the red and absorbs the rest. All of this biology: this is what makes the biosphere possible–for that I am thankful. It is what keeps our spaceship Earth a home for us humans.

It also seems that we will have vaccinations soon and a new Administration. And I’m optimistic that scientists will play an important role in the tasks ahead–there are so many.

Happy thanksgiving…
