Hereโ€™s another edition of โ€œannoyingly poorly-taken zoomed-out bird photos in Singaporeโ€

Awesome stuff - how are you dealing with the ontology issues?

Then again students could just copy paste the whole instruction set as a prompt and copypaste the answerโ€ฆ thereโ€™s no winning if the student isnโ€™t interested in effort.

Some prof went goblin-mode on AI. I thought this is actually a pretty great idea to 1) force students to at least read and comprehend the equation, 2) understand LLM prompt-response stochasticity and 3) disable student non-critical copy-paste tendencies.

Writing Resources Writing is a huge part of any career in science, and for many writers โ€“ no, for most writers โ€“ itโ€™s a daunting challenge. But itโ€™s not a challenge that you have to tackle alone. Thatโ€™s a lesson I wโ€ฆ

Your occasional reminder that I keep a curated list of resources for scientific writers that I find helpful - books, blogs, software, all kinds of things. Here it is:

Bats Hunt Migratory Birds - Little, Big Science For years, scientists found only clues suggesting that bats prey on songbirdsโ€”for example, feathers in bat droppings and bird wings discovered beneath hunting grounds. But the full picture was missing...

Looks like Batman killed and ate Todd, and the Joker wasnโ€™t even involved. This is macabre!

thatโ€™s the Japanese vernacular for some chrysomelid leaf beetle Hispines (=bristly).

Makes sense since theyโ€™re species with spines within a group that generally are spineless (Agonita? Gonophora?) within a group that ARE generally spinyโ€ฆ

4) breeds in the felled host for its next macabre cycle. The paper says โ€œentomopathogenicโ€ - Iโ€™m confused on how to classify them. As parasitoids (immatures that kill host internally during development) or as predators (free-living adults targeting prey for food)?

3)slither into host bodies (likely through a spiracle, YUCK!) to release a cocktail of symbiotic pathogens that then kill the host.

This is some high tier assassin specialist build right there- like a Zerg Roach Corpser build that targets air units. Natureโ€™s stranger than science fiction!

Electrostatics facilitate midair host attachment in parasitic jumping nematodes | PNAS Jumping can be hazardous for entomopathogenic nematodes (EPNs) as those that fail to attach to an insect host face death by predation or starvation...

How amazing is this! These entomopathogenic roundworms:

1) can coil their bodies to jump up >20x their length

2) use their -ve electrostatic bodies to home in on flying prey (which generate +ve potential)

Thereโ€™s a genus of cylindrotomid crane fliesย named ย ๐˜“๐˜ช๐˜ฐ๐˜จ๐˜ฎ๐˜ข. Largely distributed across the Northern Hemisphere.

About 10(?) described species.

None of them named nuts.

Yet.

What an opportunity.
