Bird Populations In Decline, Real Life Sci-Fi Disasters, Brain Wiring. Sept 20, 2019, Part 2

There may be almost 3 billion fewer birds in North America today than there were in 1970, according to a study published this week in the journal Science. The decline over time works out to a loss of about one in 4 birds. However, the decline does not appear to be evenly distributed.

Then, journalist Mike Pearl investigates what the world would look like after technology breakdowns, a real-life Jurassic Park, and other sci-fi doomsday scenarios in his book, The Day It Finally Happens.

Finally, new research on the brains of people who paint with their toes reveal how our limbs affect our internal maps from birth.
