Welcome to STEMology – Show Notes
Season 1, Episode 32
Ghostly tardigrades, wormy vulva milk, projectile crying and globe-skimming globe skimmers
In today’s episode of STEMology… Sophie & dave will discuss about
A fossilized 16 million year old tardigrades, worm’s self-destructive vulva yolk milk for its offspring, the science behind squirting milk from eyes, and the theory of dragonflies’ ability in crossing the Indian ocean
So they’ve been described as a ghost lineage for paleontologists … apparently they are like a ghost lineage for paleontologists because they have almost no fossil record
It turns out that as worm and mothers age, they secrete a milk like fluid through their vulva that is consumed by their offspring to support their offspring’s growth. So it’s a form of primitive lactation that is both selfless and sacrificial.
So faulty ducts might be the reason that people can shoot milk out of their eyes.
Dragonflies can detect and select favourable winds. Winds that propelled them up. So they, exhibit a behaviour called slope soaring, which is basically where they find thermal currents that propel them up the way. And you can show that they will preferentially find their way into that
And here’s the link to the paper that Dave refer to on the show!
