What’s more efficient: a four way stop or a European-style roundabout? Watch how Adam Savage, Jaime Hyneman, and The Mythbusters team put it to the test to find out the answer. (And if this video disappears, you can find out in the Hypermiling/Crash Cushions episode on Amazon Instant Video.)

In the archives: more experiments.

The size of a human fingernail, this tiny glass frog in Costa Rica is a wonder to watch. In this clip from the Discovery Channel’s Speed of Life, you can see the glass frog’s rice grain-sized, red heart and internal organs through its translucent belly skin.

Costa Rica has 13 species of glass frogs, and there are more than 100 species across Central and South America. However, because they are small, arboreal, nocturnal, and can live in extreme, wet areas, they can be hard to spot. Luckily, we have the internet:

Via National Geographic, this is Ecuador’s Hyalinobatrachium pellucidum glass frog.

There are more frogs and more videos about camouflage in the archives. 

Maersk’s Triple-E is a new class of fuel-efficient container ships, designed for lower speeds and CO2 emissions. The 400-meter long ships break the record in container ship capacity and are expected to be the world’s largest ships in service. With the Discovery Channel, Maersk is giving a sneak peek of the construction of one of their massive vessels at the DSME shipyard in Okpo, Korea with this 76-second time-lapse.

More time-lapse videos and more world records in the archives.

How does lightning form? Evidently we’re still trying to figure it out! It all starts in the clouds where both ice crystals and hail stones form: 

Scientists believe that as these hail stones fall back through the rising ice crystals, millions of tiny collisions occur. These collisions build up an electric charge which is stored in the cloud like a battery. ”A cloud is very much like a battery, but a battery with a much higher voltage than your typical flashlight battery… not 1.5 volts but 100 million volts.”

But what scientists don’t know is exactly how this electric charge generates lightning. “What remains a major meteorological mystery is how it is that ice particle collisions result in the generation of lightning. We’re very much in the middle ages on that problem.”

You’re made of carbon, you’re made of oxygen, there’s iron in your blood. All of those things had to be generated inside the core of a star. There’s no other way to get them. So when you think about star stuff, look around you. Everything that you’re made of, everything the world around you is made of had to come from the belly of a star that blew up a long time ago.
