Jesse’s talk on the Environmental Trinity opened the Breakthrough Dialogue 2024 in Sausalito. Roger Pielke Jr kindly posted the talk in his substack, The Honest Broker. A pdf of the talk is here.
Doomslayer, Marian Tupy’s newsletter at Human Progress, features polyploidy and Ohalo Genetics in its 26 May post, and includes a comment from Jesse Ausubel about the good prospects for crop yields.
NOAA has posted the video of their ‘Omics Seminar Series: eDNA-Dominant Marine Fish Species Characterize Coastal Habitats presented on 28 February, 2024 by Mark Stoeckle and Jesse Ausubel. The 1-hour seminar is full of new results and ideas about using eDNA data to characterize marine regions and features Mark’s excellent graphics.
Title: eDNA-Dominant Marine Fish Species Characterize Coastal Habitats: an eDNA-Based Classifier Approach to Aid Marine Biogeography and Ocean Monitoring by Mark Stoeckle & Jesse Ausubel
Abstract: A small minority of species typically account for the great majority of individuals or biomass. Here we characterize marine coastal habitats based on abundance of marine fish environmental DNA. We designate the ten most eDNA-abundant fish species in each habitat as eDNA-dominant species. eDNA-dominant species are similar within but differ among habitats and seasons and accord with abundance by traditional survey methods. “Classifiers” based on eDNA-dominant fish species could help map marine fish habitats and monitor changing oceans. Advantages include relatively low sampling requirements, a single technology applicable to diverse habitats, and ease of application to multiple datasets.
We have long focused on power density as the central arrow of energy system evolution. The recent achievement of the Joint European Torus (JET) to set a new fusion energy record of 69.26 megajoules of heat released during a single pulse over six seconds from only 0.21 milligrams of fuel, equalling the energy released from burning 2 kilograms of coal, prompts us to update our classic figure, below and as a pdf. Thanks to long-time PHE research associate Dr. Nadedja M. Victor, now at US DOE’s National Energy Technology Laboratory.
Fuel mass per energy, including nuclear fuels. Economies of scale favor fuels suited to higher power density, thus decarbonization and finally nuclear sources, at least 10,000 times more compact than hydrocarbons. The recent JET fusion experiment achieved density 10,000,000 times coal with deuterium-tritium fuel. Note: *CANDU is a pressurized heavy water reactor.

The St Andrews Prize for the Environment of the University of St Andrews recognizes and supports innovative and inspirational responses to environmental challenges. In 2023, Jesse Ausubel joined the jury, which awarded the $100,000 2023 prize to Alianza Ceibo for their Indigenous-led effort for protection of the Upper Amazon Rainforest.
