Nobody should be learning biology, or philosophy of biology from Judith Butler. Pure obfuscation.

Luis Leloir discovered a completely new class of biological compounds – sugar nucleotides – and showed that they are fundamental to the metabolism of carbohydrates. He was awarded the 1970 Nobel Prize in Chemistry.

Spots and stripes weren’t exactly in fashion among early mammals during the Age of Dinosaurs.

The early mammals that lived alongside the dinosaurs upwards of 150 million years ago were likely covered in dark and dusky greyish-brown fur, according to a quantitative reconstruction of Mesozoic mammal coloration in Science, hinting at their shrouded and nocturnal nature. scim.ag/4218WLF

Critical role of fossils:
"notion that insect pollination began with the origin of angiosperms is still widespread. Herein we highlight how all the known insect orders with extant and/or extinct pol-linator representatives radiated long before the evolution of flowering plants."
📢Paper alert!
Fossil record is fundamental to elucidating the origin and evolution of insect pollination, as well as informing on present-day plant–pollinator interactions.

Great quote.
Carl Sagan, in one of my favorite books, The Demon-Haunted World, says the mismatch between a society build on a foundation of high technology and public misunderstanding or ignorance of that foundation "is a prescription for disaster."
Without STEM a technological society stalls, then starts to skid, then falls precipitously as knowledge needed to maintain it disappears with the last STEM-educated people dying. But I think I'll let Carl Sagan (in Demon-Haunted World) make the point. HT @SashaGusevPosts for RT

It’s the first time a frog—or any amphibian—has been observed pollinating a plant, researchers reported in 2023.

Stand Up for Science is asking people to share why they stand up for science. OK, here is what I stand for:
1. Science is the engine of long term prosperity. 200 years ago most people lived on less than the equivalent of $2 per day. Not anymore.

“It’s a paradigm shift to know that the silent X doesn’t stay asleep,” says Dena Dubal, a neuroscientist and neurologist at the University of California School of Medicine in San Francisco, who led the study.

Republicans have criticized pediatric gender medicine for being based on weak science. And yet instead of promoting better research, they have just sought to outright cancel studies on the subject, such as these animal based studies:
Yesterday, @NIH cancelled seven grants for transgender experiments on animals including:
- $532K to “use a mouse model to investigate the effects of cross-sex testosterone treatment”
- $33K to test “feminizing hormone therapy in the male rat”

No, that’s not an eel, or a snake… or a worm. his critter is a legless amphibian! Meet Beddome’s caecilian. Growing ~10.8 in (27.5 cm) long, it inhabits parts of India’s Western Ghats mountains. When threatened, it can secrete smelly fluids from its skin & burrow into the soil.

This is the most momentous and dangerous time for Europe.
And we are ready to step up.
