Blood is rust… hemoglobin= vitamins,minerals(iron)+oxygen=rust. We’re literally running rust through our veins…along with plasma which is about 92+%. Just an informative comment.
people are worried that people aren’t as interested in nephrology anymore so they’ve started a competition based on March Madness which is “apparently dominates conversation in the US at this time of year” APPARENTLY
Vortex rings may look relatively calm, but they are concentrated regions of intensely spinning flow, as this poor jellyfish demonstrates. The rings form when a high-speed fluid gets pushed suddenly (and briefly) into a slower fluid. In the case of this bubble ring, a burst of air is pushed by a diver into relatively still water. The vorticity caused by the two areas of fluid trying to move past one another forms the ring. Like a spinning ice skater who pulls his arms inward, the narrow core of the vortex spins fast due to the conservation of angular momentum. Meanwhile, the bubble ring moves upward due to its buoyancy, pulling nearby water in as it goes. This catches the hapless jellyfish (who relies on vortex rings itself) and gives it quite a spin. But. don’t worry, the photographer confirmed that the jelly was okay after its ride. (Video credit: V. de Valles; via Ashlyn N.)
i just saw annihilation! i liked it a lot. there were like two points where the cgi went from cool to silly but one of them was followed by my favorite part of the whole thing. also i liked the part where they really tried to say or know things about biology. they tried. they did not– succeed
