Last night, the chapel facade of Magdalen College was lit up ahead of #RareDiseaseDay.

A disease is classed as rare when it affects fewer than 1 in 2000 people and there are over 3.5 million people living with a rare condition in the UK alone.

In celebration of Darwin Day 2025, Darwin Online has issued the largest collection of Darwin caricatures ever assembled, including, they claim, 30 that were previously unknown.

Here’s a link: https://darwin-online.org.uk/Caricatures.html

Charles Darwin was born OTD in 1809.

Though best known for evolution by natural selection, I’d venture that he devoted more time, and more published pages, to plant physiology and behavior than any other subject.

It was all to serve his evolutionary project, but still.

International Day of Women and Girls in Science 🧪
This image is a promotional and motivational message for the International Day of Women and Girls in Science, which is celebrated on February 11th. The phrase in Spanish, "Las mujeres ya no lloran, las mujeres calculan, investigan y descubren" (translated as "Women no longer cry; women calculate, investigate, and discover"), is a strong statement emphasizing the role of women in STEM (Science, Technology, Engineering, and Mathematics) based on a liric from a Shakira's song.

When I moved to DC in 2019, there were ads touting the climate change benefits of taking public transit.

One, which I had to walk by every day, claimed climate change made sharks bite people more. That's nonsense. I investigated.

It turns out this ad was misquoting some of *MY* research!
Is Climate Change Causing Sharks To Bite Humans? Metro Thinks So
Taking public transit reduces greenhouse gas emissions. But does it change shark behavior? Scientists are dubious.

For today's project, I'm having to do a bit of copy-pasting of text from a PDF to add information to a quarto website. Which brings me back to one of my favourite #rstats tricks, and possibly my favourite function name! stringr::str_squish()
Code snipped showing the tidy up of two sentences which are initially very broken up by line breaks and extra spaces, using stringr::str_squish(). # One of my favourite R tricks when copying from a PDF - because we all have to do that at some point! stringr::str_squish( "Here's some text that has come from a pdf and, slightly irritatingly, has lots of linebreaks that it would take ages to delete one by one. Oh and also the odd extra space.") #[1] "Here's some text that has come from a pdf and, slightly irritatingly, has lots of linebreaks that it would take ages to delete one by one.

The Encyclopedia of Evolutionary Biology is releasing a second edition in 2025, and my updated chapter, introducing the Coevolution topic section, is online already! (Reach out for a PDF copy if you don't have a subscription)

Screenshot text: Coevolution simply means evolving together, and any pair of species that affect each other’s evolution may be said to coevolve. There are many ways in which interactions between species may cause them to coevolve. The most straightforward and widely cited form of coevolution is also the most restrictive. Strict-sense coevolution is specific, resulting from direct interactions between individuals of two different species; reciprocal, such that the interaction creates natural selection acting on both species; and simultaneous, such that adaptation of one species to interaction with a second species results in adaptation of the second species to the first. Interactions with other species may also create new ecological opportunity... Interactions may create opportunities for reproductive isolation to evolve between populations... The nature and coevolutionary outcomes of many species’ interactions can depend upon the broader environmental context in which they occur. Screenshot of Fig. 2 from Yoder (2025), captioned: Plant-pollinator interactions affect traits important in plant species delimitation. (A) Animal pollination, by a honeybee (Apis mellifera) visiting milkvetch (Astragalus trichopodus). (B) Wind-pollinated Timothy grass (Phleum pratense) with exserted stamens releasing pollen. (C) Floral traits are more likely to be important in the taxonomic descriptions of plant species when those species are pollinated by animals, rather than wind or water. Photos in (A) and (B) by the author, all rights reserved. Data for (C) from Grant (1949) Screenshot of Fig. 3 from Yoder (2025), captioned: Diversification driven by species interactions. (A) Populations of an associate species that become locally adapted to their host may have patterns of genetic differentiation (arrows) that mirror genetic differences between host populations. Coevolution between two interacting lineages over evolutionary time may lead them to have congruent phylogenies (B), but this pattern may also occur if one lineage depends strongly on the other without exerting reciprocal selection. Coevolution over ecological timescales may also lead to phylogenies that are congruent in shape but without simultaneous speciation events (C) or largely incongruent (D) if pairwise associations between species shift frequently.

'The Aurora Tree', a stunning pic by Alyn Wallace, shows an incredible visual coincidence between the bare branches of a foreground tree and the brilliant glow of a far- away aurora.

The pic was taken in Iceland in March 2017.

The image shows an incredible visual coincidence between the bare branches of a foreground tree and the brilliant glow of a far-away aurora. The predominant color of the aurora is bright green with an intriguing reddish tinge at left of the pic.

One of the decisions I am proudest of in my role as first year lead has been switching to an open access textbook. I can't control inflation and the cost of living but I can reduce unnecessary additional costs. We use Open Stax openstax.org/details/book...
