Designer Eleanor Lutz used high-speed video of five different flying species to create this graphic illustrating the curves swept out in their wingbeats. The curves are constructed from 15 points per wingbeat and are intended more as art than science, but they’re a fantastic visualization of several important concepts in flapping flight. For example, note the directionality of the curves as a whole. If you imagine a vector perpendicular to the wing curves, you’ll notice that the bat, goose, and dragonfly would all have vectors pointing forward and slightly upward. In contrast, the moth and hummingbird would have vectors pointing almost entirely upward. This is because the moth and hummingbird are hovering, so their wing strokes are oriented so that the force produced balances their weight. The bat, goose, and dragonfly are all engaged in forward flight, so the aerodynamic force they generate is directed to counter their weight and to provide thrust. (Image credit: E. Lutz; via io9)

They turned RNA into an anti-virus program. That is amazing.

Let me restate this in case it didn’t sink in the first time

Researchers physically DELETED ALL TRACES of the HIV virus from a human cell.

ALL OF IT.

IF YOU ARE NOT EXCITED ABOUT THAT I DON’T THINK YOU KNOW WHAT HIV IS

What is the universe made of? We only know a tiny fraction  4 percent  of the answer. From our little corner of the cosmic map, how do we know what else is out there? Luckily, we have space messengers (otherwise known as cosmic rays) that bring us data from parts of the cosmos far beyond our reach. Veronica Bindi explains how cosmic rays transmit information about our universe from the great beyond.

Watch the full lesson here»

That number, 4 percent, never ceases to amaze me. That all of the visible, touchable, seeable matter that makes up all of everything is less than one-twentieth of the whole pie!

Luckily, not knowing is half the battle! At least when it comes to scientific curiosity.

This week’s episode of It’s Okay to be Smart is pretty “Bat-Ass.” For instance, did you know bat poop keeps little bats warm? …Aww?

Watch it here

Have you watched my…

Na-na-na-na-na-na-na-na

na-na-na-na-na-na-na-na

bat video yet?

Check it out here. And here’s a post I wrote earlier with some background on the bat cave I visited to make this one. It’s one of the most unique natural wonders on Earth, but you’ll have to watch to find out why :)
