This week we're traveling to Ahmedabad, India in an episode from 2021 to see how health officials rethought extreme heat preparedness.

Now that it's official, I am so excited to share that starting July 2027 I will be joining @dartmouthears.bsky.social as an Assistant Professor of Stable Isotope Biogeochemistry/Geobiology! I still honestly can't fully believe it, and I can't wait to get started!

Lipids are kind of the ignored middle children of origins of life research. It's time they got a bit of attention, too!

Dig 10 feet underground, anywhere on Earth, and the ground temperature will be a balmy 50 to 60° Fahrenheit (10-15° C). When you tap that ambient heat and hook it up to a heat pump, it becomes the world’s most efficient form of heating and cooling.
