Yep: A survey of 500 talks at biology meetings indicates that "Two-thirds of the attempts at humour during these talks fell flat, drawing either polite chuckles or no laughter at all" www.nature.com/articles/d41... #academia

Knock knock, no one’s there. Study finds scientists’ jokes mostly fall flat
Survey examines how often academics attempt jokes during conference talks — and how these attempts at comedy land.

Very effective illustration of what has happened to Florida's coral reefs in response to anthropogenic climate and environment change. The loss of this important ecosystem is all but complete - attempts to rescue it discussed here: www.pnas.org/doi/10.1073/... 🪸🧪🌊
A schematic image showing Recent changes in reef zonation of western Atlantic coral reefs, brought about by lack of recruitment of elkhorn, staghorn, and massive boulder corals. Without these key reef builders, the reefs have already measurably eroded. Image credit: Rashpal Dhilon. Adapted from ref. 6, which is licensed under CC BY 4.0.  The panel on the left labeled Late Pleistocene to ~1978 shows a vibrant ecosystem, the middle panel (the 1980s) is depleted but still many corals remain (though some key species are lost).  The panel on the right (2020s) is like a moonscape with a few hardy species left.

🚨 Don't eat uncooked snake! Your eyes & lungs can be parasitized by pentastomids, which are a CRUSTACEAN. Adults lack so many features that they weren't believed to be arthropods at all until their DNA was sequenced (and sperm morphology, but that was not widely accepted). Yet, they are! #Crustmas 🧪
Adult male (small) and female (large) of Armillifer sp. Looks like a big and small crinkle cut french fry, also with paired hooks at the front.
