A nanobot helping a sperm with motility issues along towards an egg.
These metal helixes are so small they can completely wrap around the tail of a single sperm and assist it along its journey 1/2

2/ birds have evolved signature markings on their eggs to distinguish their own from those of any brood parasite yet cuckoos have an egg mimicking ability, and can mimic the most sophisticated markers

3/ How is it possible for the cuckoo chick to hatch first just in time to evict all the other eggs to ensure it’s own survival?
Well the cuckoo eggs are incubated longer by it’s own parent for this advance hatching sciencedaily.com/releases/20…

4/ in this video by Artur Homan you can see one born and immediately evicting the other eggs
The early bird really does get the worm. Research shows brood parasites eggs exhibit greater embryonic movements, ‘exercising’ for future strength

these are orchid bees,
iridescent green against the emerald backdrop of tropical forests in central and South America,
The males are master perfume makers, blending species specific fragrances to use in mating displays to attract females

The last domino doesn’t have anything to land on and the angle it falls at shifts each predecessor which is the 2nd wave sound you hear
The specific and interesting maths of this effect are explained here invidious.fdn.fr/EYkBctqyKic
