Beloved lepidopterist Kevin dissects some noctuid genitalia in the Visible Lab, which he has decorated to look like the penalty box at a hockey game. He is wearing a Pens jersey and a hockey helmet while he looks thru the microscope.

I thought our new β€œvisible lab” space felt like a petting zoo but @mothpotato.bsky.social had a much better idea

Birds That Don't Exist: Niche Pre‐Emption as a Constraint on Morphological Evolution in the Passeroidea We use topological data analysis to reveal a persistent morphological gap in a major group of songbirds (superfamily Passeroidea). The gap remained unoccupied for millions of years, even though nearb...

I’d be happy to go over the economics with you (been on the core organizing committee for 4 years, chief organizer for 2), but this is far and away the most cost effective way to offer a virtual meeting and has been great for global engagement

If there were ever a species that would be the right one to do conservation on, it’d be this.

🐳 Large, charismatic
🐳 Easy to track
🐳 Of interest to tourists
🐳 Near many universities, aquariums
🐳 Clear risks

and yet down to <400 individuals, and we’re seeking to deregulate

FAQ for NSF Graduate Research Fellowship Program (NSF GRFP) return without review (RWR)

An NSF spokesperson just responded to our request for percentages:

"NSF declines to provide the data. As stated below, we do not have any additional information to share beyond what is already included in the FAQs: www.nsf.gov/funding/info...

27.02.2026 17:57 β€” πŸ‘ 20    πŸ” 7    πŸ’¬ 1    πŸ“Œ 1

The last-minute change in eligibility criteria excluded second-year grad students, so the total number of NSF GRFP applications is likely to be MUCH smaller.

We're playing word games if they don't tell us % of applications returned without review.

I appreciate @klangin.bsky.social's work on this!
