Word of the day is β€˜swullocking’, from 19th-century East Anglian dialect: sultry, sweltering, and sudiferous (sweat-inducing).

#BiologyLetters Spiders use different traits to capture prey, including webs or fangs to restrain prey before delivering their paralytic venom. But is there a trade off between venom potency and body size or silk use in prey capture? royalsocietypublishing.org/doi/10.1098/... #ecology #evolution

Big thanks to all media outlets that have covered our recently published work on spider venom potency thus far! I have been blow away by the interest and support everyone has showed. Grateful to @drivetime.bsky.social @wlrfm.bsky.social and
Galway Bay FM for having me on their shows on Thursday.

Harvard researchers devastated as Trump team cuts nearly 1,000 grants Nature talks with scientists about an uncertain future as the US government lays siege to their university.

As the US government slashes Harvard’s funding, Nature has learnt that researchers at the university have lost nearly 1,000 grants worth more than US$2.4 billion.

Along with our research on spider venom potency published in Biology Letters, we were kindly asked to prepare a seminar discussing the manuscript for @royalsocietypublishing.org/@cassyni.bsky.social's "Ecology and Evolution Seminar Series" doi.org/10.52843/cassyni.slp5xv. It's free to watch! Enjoy!

Blurred background is a colour photograph of two people (on the left one in checked red/blue/white shirt and glasses, on the right one in blue shirt with blue glasses) looking at specimens in jars on shelves. In the foreground in focus is a large old fashioned looking specimen jar with an unidentifiable specimen within it. Over this the title of the podcast 'The "Perfect" Specimen is written in white text. In the top left hand corner the Natural History Museum logo appears in white.

Finally, we tested how venom yield scaled with body size, finding allometric scaling close to 0.75, suggesting that metabolic costs are one of the main drivers of venom production, similar to what was found previously in snakes (onlinelibrary.wiley.com/doi/abs/10.1...).

We also tested for evolutionary trade-offs between venom potency, body size and silk use in prey capture but find no relationship between either size or silk use with venom potency which was unexpected and is both supported and contested by other studies in the literature.

By comparing over 70 species we show that spider venoms have evolved to be phylogenetically prey-specific by testing how venom potency changed when tested on animals closely related to a spiders diet compared to when tested on species more distantly related to their diet.

Renewal of NIH grants linked to more innovative results, study finds Nature - Survey of hundreds of scientists’ work suggests that cutting off funding disrupts focus and reduces the novelty of research.

Innovation takes time

US scientists who received renewals from the NIH over the past four decades produced more novel research than those who didn’t
