How do we protect what we don’t know exists?

How many species are there on Earth? In biology, this is one of a fundamental question that we still don’t have a very good answer for. Imagine if chemists didn’t know all the elements of the periodic table, or if physicists didn’t know all of the particles of the standard model. Knowing how many different species there are is information we need to know in order to protect the environment, but it’s a lot harder than you think!
Check out last week’s video, where we find a weird caterpillar in the Peruvian Amazon and ask “How do you discover a new species?”

Bees see the world in some very interesting ways
Click here to SUBSCRIBE, it's FREE! -- http://bit.ly/iotbs_sub
To begin this video, we launched a little confetti to celebrate the fact that I am now "Dr. Joe", since I successfully defended my Ph.D. in molecular biology! Woo! But you don't have to call me "Doctor."
Anyway, spring is in the air!! We're all thawing out from winter's chill, and for bees and flowers this season is about one thing: Feeding and fertilizing. Bees are amazing social insects, and their relationship with flowers is one of nature's coolest examples of "mutualism". It got me wondering: How do bees see the world? Enjoy this look at how bees see in ultraviolet and even sense electric fields!

As winter approaches, V-shaped flocks glide overhead as the world's birds begin their long treks to warmer climates. Humans used to have some pretty crazy theories about where birds went for winter, like the moon, or to the bottom of the ocean.
How did we learn the real story? And where DO birds go for winter? What are the longest bird migrations? How do birds store up energy for their long journey? How do birds navigate? Why do they fly in a V-shape?

When is now? Seems like a pretty simple question… just look at your watch. But do you and I share the same “now”? Let’s journey from Einstein’s thought experiments about relativity to cutting edge neuroscience research to try and answer that question.

Are you a left-brained person or a right-brained person? Spoiler: You're neither. Each of us uses both sides of our brain for most of what we do. But still, there are a number of brain functions that do show lateralization, where they are localized to one side or another. Why is this? And how does it influence our definition of consciousness? People with "split brains" can help us figure it out.
Special thanks to Dr. Michael Gazzaniga for his help researching this video!

The origin of life is one of the most important mysteries in all of science. When did life begin? How did life first evolve from chemistry? Where did life get started? In some primordial soup or somewhere else? Let’s journey back to the origin of life, as best as we know it, from the RNA world do the last universal common ancestor of everything alive today.

How do zebras get their stripes? How do leopards get their spots? And how do giraffes get their giraffe-shaped thingies, whatever they are called? Would you believe the answer is… math? This is the story of a WWII wartime codebreaker and his quest to decode nature’s most beautiful patterns. Alan Turing uncovered a simple code that explains everything from stripes to spots and all the patterns in between… he was just too far ahead of his time. Only recently have biologists found evidence that his pattern-forming system

There is an absolutely weird, but surprisingly common phenomenon called sensory adaptation that you experience every day in countless ways without even realizing it. Without this very strange phenomenon, you would be lost, overwhelmed, and completely unable to navigate the external world. In this episode, we’ll explore the many ways your brain “tunes out” most of what’s going on around you so that you can be the high-functioning smart people that we know you are.

The idea of the lone genius creating everything isn’t just misleading. It’s harmful and wrong. Innovation thrives when people work together, and rather than nice linear paths, new ideas come from chance events and unexpected connections. This video tells the story of one such invention, and offers a new idea about how new ideas are really born.

8:26 Bubbles, for your health!
9:33 Putting the club in soda
10:13 Needles and drugs
11:01 A tower in Paris
11:58 Quantum bros
12:53 Very VERY tiny things
13:37 This physicist hates cats
14:20 Mr. Helix and the messengers
15:18 It's all coming together
16:08 The best part of the story

We've heard news of "peak oil" and "the end of the oil age" for years now, but we keep coming up with ways to find and pump more of it to the surface. Rising CO2 levels and the changing climate that results from burning fossil fuels mean that we should probably stop using oil sooner rather than later, though
Let's take a look at history and see how we've used different fuels, so that we might figure out when and how to make oil a thing of the past

Money. We all use it. But is it real? I mean, you can touch a coin or bill, but who decided that’s worth anything? And what about all those 1’s and 0’s getting swapped and traded by computers thousands of times per second? How are those worth anything? We trace the history of money, from physical barter to bitcoin, and discover that money isn’t just a lie we all agree to share, it’s been built on the back of technology and invention for millennia.

Why do Africa and South America fit together? Anyone who’s ever looked at a map can see that Earth’s continents are kind of like a jigsaw puzzle. The idea that continents are constantly moving and weren’t always in their current spots is a pretty obvious idea, right? You might be surprised to learn that geologists only accepted that idea recently in the past few decades, and it figuring out how plate tectonics and continental drift work required some pretty strange evidence.
