Science Friday: How you count on your fingers says what about your brain? | Why humans laugh? | Edison’s car battery is back

What does the way you count on your fingers say about your brain?

    Put down your coffee for a moment. Now, without thinking about it too much, use your hands to count to 10.

    How did you do it? Did you start with the left hand, or the right? Did you begin counting on a thumb, or with a pinkie? Maybe you started on an index finger? And did you begin with a closed fist, or an open hand?

In Good Health? Thank Your 100 Trillion Bacteria

    For years, bacteria have had a bad name. They are the cause of infections, of diseases. They are something to be scrubbed away, things to be avoided.

    But now researchers have taken a detailed look at another set of bacteria that may play even bigger roles in health and disease: the 100 trillion good bacteria that live in or on the human body.

Science Friday: On this Tiny Sphere is All the World's Freshwater | Sunlight is a h2o Disinfectant | Megafires and Tree-rings

And THIS Tiny Sphere is All the World’s Water *That We Can Use*

    A few days ago, we wrote about a remarkable graphic released by the USGS, showing all the water on Earth—freshwater, saltwater, water vapor, water in plants and animals; all of it—rolled into a sphere.

    That sphere was only 860 miles in diameter, fitting comfortably between Salt Lake City and Topeka, Kansas, on a map. It was striking, especially considering that the water available for humans use in our daily lives is only a very small fraction of that; the vast majority of the Earth’s water is saltwater, and most of the freshwater is tied up in glaciers.

Science Friday: What if Pterosaurs Were Alive Today? | The Science of Memorable Movie Lines | Physics of Spilled Coffee

What would life be like if pterosaurs were alive today?

    Paleontologists don't always speculate about the existence of gigantic, winged reptiles living alongside humans in the 21st century, but when they do, they back that speculation up with plenty of scientific evidence.

    In this, the first installment in a two-part series, paleontologist Mark Witton explores an obviously speculative, totally puerile, and completely awesome topic — what modern life would be like in the company of pterosaurs — through a decidedly systematic, rigorous, and research-based lens. How big would these pterosaurs have been? Might we have farmed them for their meat? And perhaps most important of all: could we ride them?

White Killer Whale Spotted—Only One in the World?

Christine Dell'Amore

    The headline-grabbing all-white adult killer whale spotted off Russia this month may well be one of a kind. But the sighting may not be the first time he's been caught on camera.
