I'm in Halberstadt where I have been sent by the lovely folk over at Orbital Studies to witness and write about the 17th chord change of John Cage's "As Slow as possible" which has been playing on an organ here since 2001 and is projected to keep playing until the 2600s.

I'm incredibly honored to be one of the inaugural winners of the Ctrl-Z award. The sequence of events preceding and following this retraction were harrowing (and are honestly still stressful), but I hope this will be an opportunity for more open dialogue about mistakes + self-retraction in science.
Retraction Watch@retractionwatch.com · yesterdayThe Center for Scientific Integrity is proud to announce the inaugural winners of the 2026 Ctrl-Z Award. Named for the universal keyboard shortcut for “undo,” the Ctrl-Z Award this year honors @cetaceanneeded.bsky.social and @katelaskowski.bsky.social for choosing transparency over reputation.

Maintenance of phenotypic divergence in two sympatric monkeyflowers with weak reproductive isolation
Sympatric species often exhibit permeable reproductive barriers, yet many of them coexist as phenotypically distinct entities. One way to account for this apparent paradox is that selection on loci th...

We (@rileyshultz.bsky.social) tracked a recessive mutation from birth to death in honey bees. It causes ivory eyes. We collaborated across the continent to identify the mutation and it's downstream effects. Ultimately it is purified through selection on drones. We think Hamilton would be pleased!
Molecular Biology and Evolution@molbioevol.bsky.social · 6d agoShultz @beeharpur.bsky.social et al. documented the trajectory of a spontaneous deleterious mutation from its origin in a single queen to its extinction, directly observing how haplodiploidy exposes recessive alleles to immediate purifying selection 🔗 doi.org/10.1093/molbev/msag156 #societyjournal
Remember those extreme wildfires in 2020 and 2021 that set many of CA's giant sequoias ablaze? It would have been about 4x worse without the prescribed burns some groves got within the previous decade. Another study from @ucdavis.bsky.social showing Rx burns work. www.ucdavis.edu/climate/news...

Did you know that the flowers of avocado trees change sex every day? Scientists have noticed this nearly 100 years ago but only now do we how it works. Life is amazing.
Avocado flowers switch sex daily—now we know why
New work explains how avocado trees coordinate a complex reproductive strategy, switching every day between male and female

Stalked jellyfish are a super rare group of jellies that don't float, but instead anchor themselves to the seafloor using a special 'foot.' To move, they do cartwheels, holding onto the seafloor using sticky pads between their pompom tentacles. 🧪🌿🌊
Really remarkable plant sex allocation study here: hermaphroditic avocado plants alternate sex roles twice daily and hence generate balanced sex allocation- controlled by ancient trans-species polymorphism. Heard a bit about this jaw-dropping work at UC Davis last year - great to see it out!
Jeff Groh@jeffgroh.bsky.social · last wk.Avocados come in 2 varieties - A-types start each day female and switch to male midday. B-types do the reverse. In work just published from the last chapter of my PhD, we show this system evolved 40+million yrs ago and is regulated by alleles of 1 transcription factor www.pnas.org/doi/10.1073/...
