Today my @nytimes.com colleagues and I are launching a new series called Lost Science. We interview US scientists who can no longer discover something new about our world, thanks to this year‘s cuts. Here is my first interview with a scientist who studied bees and fires. Gift link: nyti.ms/3IWXbiE

Bhaumik Prize Postdoctoral Fellows Program – UCLA

The Departments of Chemistry and Biochemistry and Physics and Astronomy at the University of California, Los Angeles (UCLA) invites nominations for the Bhaumik Prize Postdoctoral Fellows Program. This newly instated program seeks to bring the brightest young scientists to UCLA to expand their scientific training, make new discoveries, and network with interdisciplinary scientists of all stages. The Bhaumik Prize Postdoctoral Fellows Program is made possible by the philanthropy of physicist and entrepreneur Dr. Mani L. Bhaumik. The program supports three fellows annually for a three-year postdoctoral position.

That's quite the chart annotation.

www.nature.com/articles/d41...

A chart of "Major concerns of PhD candidates." The top text says, "Financial pressures top the list of concerns faced by PhD candidates, but concerns differ among the sexes. Those studying in the United States rank the political landscape as their main worry." The chart shows that in the full survey, political landscape is the biggest concern for about 20% of students (a bit higher for women than men) but there's an annotation saying "In US PhD students, this rose to 64%". Overall, the highest-rated concern was financial pressures at around 40%.

my takeaway from climate week nyc is that "climate storytelling" is a little too much "we must reimagine our deepest souls in relationship to mother nature and the moral abyss of the polycrisis into which we must now stare" and not enough "ok but get a heat pump"

New paper by @matthewgoss.bsky.social (along with @hannahskenagy.bsky.social and @coletteheald.bsky.social)! Matthew reexamined a bunch of old* SOA experiments, to get a better handle on the oxidant and RO2 chemistry involved.

* including some from my postdoc, ~20 years ago 😬

Our paper examining the chemical conditions of past chamber studies is out! This work explores assumptions made when creating SOA parametrizations based on laboratory data, and can hopefully point to ways of improving model representation of SOA.

Trump: "It used to be global cooling. If you look back years ago in the 1920s and 1930s they said, 'global cooling with kill the world.' Then they said 'global warming will kill the world.' But then it started getting cooler ... it's the greatest con job ever perpetrated on the world."

The New York Times piece today about US science is terrible and wrong—in many ways.

I could write a whole article about this, but as one example:

“To close observers, the original crisis began well before any of this…”
No. I’m a close observer of science, and this is incorrect.
