Screening, sorting, and the feedback cycles that imperil peer review The process of peer review is vital to contemporary science, but is also under enormous strain. This study uses mathematical models to dissect the threats to the long-term viability of peer review, su...

1. Kevin Gross and I have a new paper out today PLOS Biology.

We used economic models based around screening games and the market for unpaid labor to highlight a meltdown cycle threatening peer review.

We need to convince society journals to use independent, non-profit publishing platforms.

Other societies I belong to publish with Wiley (Ecological Society of America, American Geophysical Union). Not quite as bad as throwing money at Elsevier but still harmful to science, scientists, and universities.

I work at Moffett Field, a former Naval air base ~5 miles from the site of Super Bowl 60. We’ve been advised to work from home next week because DHS is using Moffett to fly in & β€œstage equipment”. Not sure if ya’ll already knew this, but sounds like they’re gonna show up in force on game day.

Map of water table depth across the continental United States at 30-meter resolution, with inset panels showing detail at 100km, 10km, and 1km scales in both eastern and western US locations. Color scale shows depth from shallow (blue) to deep (yellow) on a log scale.

New work from our team: we mapped water table depth at 30-meter resolution across the entire continental US.
That's ~8 billion grid cells, trained on over 1 million well observations. Highest-resolution estimate to date.

UC Merced Receives Transformational $38 Million Gift from MacKenzie Scott | Newsroom

Grateful to MacKenzie Scott for her $38 million gift ... the largest in UC Merced's history, surpassing even her own record-setting donation to our campus in 2021.
She continues to be one of the few doing billionairing right.

OK, looks like I can go back to work tomorrow. Also, whoever wrote the text for this email violated the Hatch Act.

Land change, fire, and climate weaken carbon sink in the conterminous United States The United States has experienced rising carbon sources driven by land use, fire, and climate factors.

Just out: more evidence for a weakening land carbon sink across the contiguous U.S. Proud to be part of this collaborative effort among (mostly) federal scientists! πŸ§ͺ www.science.org/doi/10.1126/...

This thread encapsulates why I have zero regrets about escaping academia - the culture is just so low key toxic. I have nothing but respect for those of you inside shining a light on it and fighting to make it better (like Colin), but I had to get out.

I’m a furloughed federal scientist. Under normal circumstances I’d be stoked so many fed agencies (finally) came over to bluesky - but these ain’t normal times. Block and move on.
