Not to mention that the boots are already on the ground, and despite some paperwork, "we" can get people working on important topics almost immediately.

Stephen Jay Gould was born OTD in 1941.

“Organisms are not billiard balls, propelled by simple and measurable external forces to predictable new positions on life's pool table.... Organisms have a history that constrains their future in myriad, subtle ways.”

Confused writing is usually a symptom of confused thinking. As we struggle to clarify writing, we clarify our thoughts. AI writing aids rob us of that struggle, leaving clean-looking text and thoughts still confused for lack of inspection. Writing is not just a product; it is a diagnostic tool.

Would solar dimming also reduce rate of oxygen production from marine algae…though, the pH would mess a lot with that, too. Isn’t the Anthropocene grand!

Every year I fund a small award for science graduates at my very small town high school. It honours the person who made me love the sciences and particularly biology. She was a fantastic teacher just by being human and talking to us country bumpkins like we mattered and could be something more
