October 07 How Habits Can Change Your Life (and Your Brain)
You have the power to change your brain!
Make watching our videos a habit and SUBSCRIBE! ►► http://bit.ly/iotbs_sub
↓↓↓ More info and sources below ↓↓↓

Uploaded 28-08-18

Got a bad habit you just can’t seem to break? That’s because it’s literally wired into your brain.
Every single thought, action, and feeling changes your brain. When repeated enough times, a habit is formed. This week we’ll talk about how an advertiser in the early 1900s got half of Americans to pick up a new behavior - and make it a habit we all know today.

And remember: The universe will end, but not for a while… probably

I don’t want to alarm you, but the world is going to end. All of this. Gone. And scientists are certain all of this will happen. On the bright side this isn’t going to happen for 4-5 billion years. It makes me wonder: In a universe bigger than we can fathom, across eons of time, could… all of it end? Everything? The whole universe? Yes. And it probably will. Here’s how.

Note: The copy of "The End of Everything (Astrophysically Speaking)" discussed in this episode was provided free of charge by the publisher. As in "the physical copy you see on screen." I also bought the book myself because I love astrophysics! But that version is on my Kindle :)

I met Molly Burke a few months ago. She’s awesome. I absolutely love what she’s done on YouTube to bring awareness to living with disability, and turning it into ability. And her guide dog Gallop is awesome too! When Molly and I first met, we started talking about how she navigates the world, because I’m a nerd and I always steer the conversation toward science. I was not prepared for what she told me. She said she uses echolocation! Molly’s brain has adapted to listen to sounds in her environment in ways that most of us sighted people can’t even imagine. I went to meet her in LA and brought a special surprise, to see if my brain could learn what hers has.

October 07 Why Are There As Many Males As Females?
Evolution doesn’t pick a side!
Don’t miss our next video! SUBSCRIBE! ►► http://bit.ly/iotbs_sub
↓↓↓ More info and sources below ↓↓↓

Uploaded 22-02-18

In almost every animal species on Earth, equal numbers of males and females are conceived. Why is that? Especially in populations like lions or elephant seals, where most males don’t get to mate? That’s survival of the laziest, not survival of the fittest. It turns out that in most cases, an equal balance of the sexes is the evolutionary stable strategy. From Charles Darwin to Ronald Fisher to W.D. Hamilton to Richard Dawkins, the question of why there’s as many males as females has fascinated biologists. Today, we’ll explain why that is the way it is.

Part 2 of our special series on Human Ancestry. Watch it all: http://bit.ly/OKTBSHuman
↓↓↓More info and sources below ↓↓↓
In part 2 of our special series on human ancestry, we ask why we are the only surviving branch on the human evolutionary tree. Just 50,000-100,000 years ago, Earth was home to three or four separate human species, including our most famous cousins: the Neanderthals. New research has shown that Neanderthals were not the brutish, unintelligent cavemen that cartoons make them out to be. They were creative, smart, social, and perhaps even had complex language. So why did they go extinct as soon as Homo sapiens moved into their territory? Does any trace of them live on today? Why don’t we have Neanderthal neighbors?

October 07 Where Did Mankind Emerge From?
Viewers like you help make PBS (Thank you 😃) . Support your local PBS Member Station here: https://to.pbs.org/PBSDSDonate
Ready to untangle the branches of the human family tree?
Part 1 of our special series on Human Ancestry. Watch it all: http://bit.ly/OKTBSHuman
↓↓↓More info and sources below ↓↓↓
In part 1 of our special series on human ancestry, we tour through our family tree to meet our ancestors and distant cousins, and to find out what made us human along the way.
The story of human ancestry is not a simple progression from primitive apes to us, with all the ape/human intermediates in between. The real human story is much richer and more complex, full of branches, gaps, and shadowy parts. A century and a half of fossil finds tells us perhaps two dozen human species lived on Earth between now and the time when our ancestors split from chimpanzee ancestors. The new era of DNA and genetics is upending that story yet again.
