Hummingbirds' super-specialized adaptations

39:30  Some species of plants have evolved highly specialized flowers that only a single species of hummingbird can reach. This is to each an advantage - the flower benefits as the hummingbird only visit other flowers of the same species, and the hummingbird benefits as the only species that can feed on the abundant nectar

Dropshipping buying from Alibaba and selling on eBay, shipping direct to consumer.

"Dropshipping in its simplest terms is buying "stuff" from a vendor and reselling it yourself for more than you paid for it. You don't own stock. [i.e. you never physically touch the products you're selling] When an order is received, you buy the product and have it delivered directly to the customer."

Repairing Underground Power Cables Is Nearly Impossible

https://youtu.be/z-wQnWUhX5Y

This engineer is always interesting. He explains the reason this massive power cable failed from thermo-mechanical bending. And how difficult it was to find the failure point. And how the insulating high-pressure dielectric oil made it difficult to open the pipe without losing the valuable oil - so they froze the oil with liquid nitrogen. 

Being in the "in" group

This podcast is a really interesting discussion of how we align ourselves with people in our own "in group," even if it was just decided arbitrarily a few minutes before. It affects our judgment, our sense of fairness, our perception of others' wrongdoing, our choice of who we'll date...

And, if you take inveterate enemies and make them play on the same sports team, they reduce their ill will towards that other group. (e.g. the arrival of a Muslim soccer superstar induced decreased acts of racism and lower rates of tweets against Muslims in his home team's city.)

Child support payments - the tide is changing.

An interesting justification for spending trillions of dollars to support parents of children. Ultimately, the justification comes from data from other countries, that giving money to poor people does not make "welfare queens" but increases marriage rates (i.e. home stability,) employment, and improves lives.

Why women get more autoimmune diseases

Why do women get more autoimmune diseases? @19:10 A mother's immune system is diminished during pregnancy in order to tolerate the (presence of the foreign body - the) fetus. In the complex balance of having enough immune activity, but not so much as would attack a fetus, they end up with autoimmune diseases.

Biology of: The Dragonfly

https://youtu.be/iJi61NAIsjs

Surprisingly good documentary on dragonflies. Fun fact: their kill rate of 95%, as a predator, is way higher than any other predator (mostly around 25%) because of their incredible flying adaptations and huge eyes.
