Developed to trace military bomb drop-offs back in time to their origin, this deep dive of modern wife-are AI-assisted surveillance is, well, eye-opening.

Every life form struggles to prevent cancer
45:20 from the very first multi cell organism onwards, life has been about cells shooting at each other to prevent one feel from becoming cancer. As soon as one cell starts replicating faster, it is naturally selecting for itself.

Thinning of forests, instead of clear-cutting

BYD EV for $7800
Interesting video explaining all the people losing money on cheap EV's from China, notably factory workers enduring "slavery-like" conditions, and billions of Chinese government subsidies.

How GPS works
To get accurate position, the satellites are "told" their position from earth stations that locate relative to quasars. That enable accounting for tectonic movement.
Signals from the satellite are 50 watts, so only a quadrillionth of a watt reaches your phone - easily drowned out by jamming signals.
The signal from the satellite gets distorted on the ionosphere, adding several meters of uncertainty. Wackadoodle car propulsion idea
A very thorough discussion of the physics of a wacky compressed air vehicle that slides the wheels back and forth. He even builds a 3-D printed model of the idea. He also explains why rapid cooling as air expands is the downfall of previous compressed-air-driven vehicles, and the volume of air required to achieve range.
