Map of projected temperature anomalies next Thursday across the western U.S. from the ECMWF ensemble. The entire map is bright red and pink, indicative of extreme to record-breaking March warmth. Some location will be 25-30F degrees above average, with a few locations warming over 35F (!) above average.

All signs continue to point to an exceptional, long-duration, and record-breaking to (in some cases) record-shattering March heatwave initially centered across U.S. Southwest but expanding to much broader region next week. This is effectively a full-on summer heatwave in March.

California has had about the average amount of rain expected for this time of year, but snowpack is half of normal and melting fast.
This is absolutely evidence of #climatechange.

Proud that this work is now published!

We hope it helps orient future #Nanopore long-read sequencing studies hunting for structural variants

Also really happy to share eight new high-coverage (>100x) long-read read pools and assemblies with the #Drosophila community!

Final version @nature.com of our paper describing unconventional multicellular development in a choanoflagellate inhabiting an extreme environment. A ton of new data since the first @biorxivpreprint.bsky.social preprint (which we've kept updating).

Petunia hybrida has been bred into an incredible diversity of colors and patterns.

Most arise from mutations in the anthocyanin pathway or post-transcriptional gene silencing that turns pigment genes on and off 🧬🎨

Striking signal for much above-normal temperatures across California, the Great Basin, northern Rockies and Desert Southwest from March 15-20. Temperatures will be more typical of summer than early spring (potentially 25 degrees above normal) in many areas and monthly records could be shattered.

🌿 Postdoc opportunity in plant evolutionary ecology/genetics!

My lab in the Dept. of Ecology & Evolutionary Biology at the University of Michigan is recruiting a postdoctoral researcher to start Fall 2026.

We study plant adaptation, using weeds as model systems.

Graph of award probability of R35 and R01 from NIH factbook as a function of review rank percentile. As is apparent, 2025 is a significant departure, with lower award probabilities at all scores <40 and significant departures from norm, where even being in the top 10% is no longer a nearly certain indicator of success.

Data source: https://report.nih.gov/nihdatabook/report/302

The data is in: the NIH goalposts have shifted.

What were once almost certain fundable scores have become coin flips and what used to be likely grants have become aspirational, leading to fewer awards.

Another manifestation of how HHS policies have led to fewer awards and less science.

Here is the "effective payline" for each institute, estimated (by Claude) as the percentile where one can expect 80% probability of funding from a logistic regression fit. The effective payline has gone from a historic ~12% to 6% in 2025.

A California condor with orange tags with the number 34 on each wing is perched on a metal structure overlooking landscape of green hills with light fog rolling between. The image includes the logos for ALERTCalifornia, UC San Diego, and PG&E.

Spotted male California condor Hasso on Henrietta Peak 2. This camera is set to "patrol mode," which means it is programmed to spin 360 degrees to take six images every two minutes. We stitched adjacent images together to show his full impressive 9-10 foot wingspan.
