A paper, published in Science Advances, suggests the industrial hunting of great #whales such as #sperm, #blue, #fin & #rightwhales “masked” the ability of these underwater giants to live to great ages.

It has been known since the 1990s that Arctic bowhead whales can reach 200 years old or more, as indicated by tests on their proteins in their eyes, & by old Inuit stone harpoon tips found embedded in bowheads that had survived earlier hunts.

#Sperm Can’t Unlock an #Egg Without This Ancient Molecular Key
Using s #AlphaFold, researchers identified three sperm #proteins that seem to make #reproduction possible
Lab experiments confirmed: Male zebrafish missing newly discovered third protein were infertile, as were male mice. Their sperm swam normally but couldn’t fuse with an egg. Scientists found biochemical evidence that sperm proteins were working as a unit, both in zebrafish and humans

@GrimmReality

i would like to note that, for the #MAGA mind, the symbolism of carrying around figurative #sperm jars is not merely a bizarre display, but when combined with their clearly and multiply enunciated and delineated hatred for and opposition to #womensrights, is an implied threat of force

it's as close as they can get to politically supporting #rape as they can, without triggering anything obvious

"here take the sperm jar of my #cult hero" is not an *offer*, it's something far worse
