EPA eliminates research and development office as it begins thousands of layoffs The Environmental Protection Agency said Friday it is eliminating its research and development arm and reducing agency staff by thousands of employees.

A 23% reduction in staff at the EPA and closure of their research program will make it much easier for companies to pollute land, water, and air without being held accountable. This will hurt all of our children and grandchildren. This is very sad to watch. 🧪

Study finds AI tools made open source software developers 19 percent slower Coders spent more time prompting and reviewing AI generations than they saved on coding.

a new study found that experienced open source programmers became 19% less efficient when they used AI tools, because they spent more time prompting and reviewing AI generation output than they saved on coding.

Trump’s NIH And NSF Cuts Estimated To Cost The U.S. Economy $10 Billion Annually Economists find public R&D drives U.S. productivity growth — and pays for itself

www.forbes.com/sites/johndr...

"For every dollar spent [on science], the economy eventually produces an additional $1.71 in output. That return exceeds nearly every other form of public or private investment."

Is this YTD for 2024?

Okay I know I've got a bunch of bug needs among my followers, and y'all need to see this one LOOK AT IT

Ecological acclimation: A framework to integrate fast and slow responses to climate change Read the free Plain Language Summary for this article on the Journal blog.

A synthetic paper about fast vs. slow responses of ecological systems to changing climate, explaining how and why those responses can shift (even in sign) over time. Examples across scales and subdiscplines (population genetics, ecosystem ecology). besjournals.onlinelibrary.wiley.com/doi/10.1111/...

NSF, NASA and NIH budgets per year, inflation adjusted from 2000-2025 along with the proposed cuts. NSF includes research component only. Massive cuts across all sectors, well below support spanning 25 years.

How bad will it be? Catastrophic.

Proposed cuts to #NSF, #NIH, and #NASA will set the US R&D landscape back 25 yrs+, cause economic and job loss now, and undermine innovations to come.

But, this is the WH's *proposed* budget.

Speak up now before it is too late.

‘Scienticide’ in Argentina sparks huge protest by researchers Hundreds of activists wearing gas masks took to the streets to call out their government for slashing science funding.

Soybeans and sirloin are not incompatible with science.

But a country that only produces soybeans and sirloin is going to run into some recurring, structural problems.

How do ecological communities respond to pulse perturbations (e.g. storms, wildfires)? We have a solid theory for stable fixed points, but what about cycles, transients, or chaos? In this preprint, we introduce a unified framework for these nonequilibrium cases. 1/7

Dad: what papers are you writing rn?
Me: an exam for my course
Dad: that's not a paper
Me: I KNOW!! 🙃

Favorite word of the month: equifinality. When multiple paths lead to the same end.

Thanks!! So excited to try this!!

How do you make it?
(if a state secret, could be a good lure for ASN!) 😍

First time teaching is fun but so much admin.
First time in weeks I can sit in my sunny office and do math.
So happy.

Ahh one of my favorite islands!!

ELECTION RESULT: A team of city council members in Rolla, Missouri, have been pushing anti-LGTB policies, including a ban on drag shows and book censorship.

Voters just ousted all three of these city councilors who were running for reelection, backing candidates backed by a local LGBT group.

Made a pop dyn lecture for my bio freshmen, and I effectively called discrete-time models "seasonal models".

Because discrete vs continuous time dynamics really differ with nonoverlapping generations. And most of the time generations don't overlap because of seasonality.

in case you're wondering, "what's the harm in claiming an extinct species has been brought back from the dead" when it most certainly has not, our interior secretary is already using it to justify taking animals off the endangered species list

New paper! (arxiv.org/abs/2503.14093) I haven’t been this excited about one in a while, and I think the theory @mhab.bsky.social develops here will be a big step forward for the field. Why? Let me explain 🧵...
