Calling all phylogeneticists! With the untimely demise of CIPRES, where are y’all going for running #phylogenetic analyses?? Any other similar public servers out there with GUI submission interface??

some previews of an abc zine i'm working on! 🐦✨
a drawing of a pigeon flying and looking determined, carrying a scroll. they think "lives are depending on me!" a small red circle giving a preview of the scroll's contents says "send nudes lol". text above the pigeon says "h is for homing" and underneath that "Homing pigeons are bred to be able to find home over long distances. Before phones, they were used as messengers, even during wars to deliver crucial intel."a drawing of two pigeons kissing. the one on the right looks suspicious and asks "did you have garlic today?" the one on the left sheepishly says "uhh...no..." text above says "k is for kissing" and underneath that "a courtship ritual where pigeons lock their beaks together and regurgitate food. so romantic!"a drawing of a baby pigeon with its eyes shut going 'wehhh'. text above says "s is for squab" and underneath that "a baby pigeon! they stay hidden in their nests until they are fully feathered. a face only a mother could love..."

This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again. www.nature.com/immersive/d4...
This line graph illustrates the percentage change in agency staff levels from the previous year for nine major U.S. federal scientific and health organizations between the fiscal years 2016 and 2025. The agencies tracked include the CDC, Department of Energy, EPA, FDA, NASA, NIH, NIST, NOAA, and NSF. For the majority of the timeline between 2016 and 2023, the agencies show relatively stable fluctuations, generally staying within a range of +5% to -5% change per year. However, there is a dramatic and uniform plummet starting in the 2024–25 period. Every agency depicted shows a sharp downward trajectory, with staffing losses ranging from approximately -15% to over -25%. The Environmental Protection Agency (EPA) shows the most significant decline, dropping to roughly -26%, while the National Institute of Standards and Technology (NIST) shows the least severe but still substantial drop at approximately -15%.

The buff-tip moth (Phalera bucephala) has mastered a very particular kind of camouflage. When they close their wings up, they resemble a broken twig. Native to large parts of Europe, there's regional pattern variation that reflects the local tree species. This one best resembles birch twigs?

SINGER, our ARG inference method, is finally published and freely available online: doi.org/10.1038/s415... It was a long journey – 16 months from initial submission to acceptance. Is it just me, or has peer review gotten more arduous lately? 4+ rounds of review isn't so unusual these days...

A tricky thing about modern society is that no one has any idea when they don’t die. Like, the number of lives saved by controlling air pollution in America is probably over 200,000 per year, but the number of people who think their life was saved by controlling air pollution is zero.

Once, in Gorongosa NP, I thought that I had found Halucinogenia, a near-mythical Cambrian animal with spikes on its back. The creature turned out to be a caterpillar of Acridotarsa melipecta who lives as an inquiline in the colonies of the termite Schedorhinotermes lamanianus. Still cool, though.
