Why Do These Trees Refuse to Touch?

SciShow – Jan 21, 2020 – 4:27

Trees have “crown shyness”


How Levitating Dust Shapes Airless Worlds

SciShow Space – Jan 21, 2020 – 5:52

Secrets of Life from A Giant Pool of Asphalt
Weird Places: Pitch Lake, Trinidad

SciShow – Jan 20, 2020 – 6:11
Trinidad’s Pitch Lake is a huge, oily, and filled with millions of tons of asphalt. It may not sound like a great place to live, but the lake is teeming with microscopic life! And learning more about these organisms could give us insight into how life could exist on other, less hospitable worlds. Hosted by: Hank Green

12:09 – Another hiccup for the crisis in cosmology – do supernova really explode with the same brightness everywhere?


Why Do People Have Periods When Most Mammals Don’t?

SciShow – Jan 22, 2020 – 11:57
Few mammals actually get periods every month, or even at all, but why? Understanding what menstruation really is and why it happens could help ease symptoms & treat conditions that stem from the reproductive system. Hosted by: Olivia Gordon, who gets all the good topics.

Cannot bring herself to say “woman” in a report on periods!
But able to take a few potshots at males.

Solid info interrupted by snarky euphemisms.
