Crazy Animal Robots

Check out this crazy dog-like robot video made by MA-based Boston Dynamics. The idea is to use the robot in battle situations to transport heavy equipment through rough terrain. Looks like they really tested this guy out, getting someone try to kick it over and making it cross over a particularly icy patch of ground, then replaying both situations in slow-mo (not unlike an action film battle scene).

Now it looks like this 'BigDog' robot now has some competition from another Boston area company called Vecna. They are making a similar robot called BEAR that they promoting as "the robot that can save your skin." Unlike BigDog, BEAR stands on two legs. You can see for yourself on Vecna's website.

Ground control to Stephen Colbert

It's a crazy, mixed-up world out there, folks.

NASA held a contest to name a new "node" being added to the International Space Station next year. NASA tried to guide voters in the right direction.
The name should reflect the spirit of exploration and cooperation embodied by the space station, and follow in the tradition set by Node 1- Unity- and Node 2- Harmony.

But instead, two hundred thousand of the Colbert Report faithful voted for their own write-in nomination, "Colbert," over NASA's genteel suggestions, Earthrise, Legacy, Serenity and Venture.

Lesson learned: NASA's latest Name The Rover contest, which is running all this week, isn't taking write-ins.

Of course, NASA doesn't actually have to yield to the power of the people. We'll have to wait and see how they wiggle out of this sticky PR situation. And next time, perhaps they'll remember leave the big naming decisions in the capable hands of Siberian orphan children.

One shining moment (for mathematicians)

Basketball is a spectator sport. Mathematics is not.

Or is it? This month, hoops-loving statisticians get to ply their craft on the dunking, dribbling, alley-ooping data set which is the NCAA men's basketball tournament. Yes, mathematicians have the March Madness, too.

Scientific American obliges with a quick rundown of scientists who are getting in on the game, including University of Illinois computer scientist Sheldon Jacobson, who argues that seeding is irrelevant when it comes to picking winners in the Elite Eight and beyond. His study was published in the Journal of Gambling Business and Economics--the very existence of which merits a study of its own.

But if you really want to get your brain in a bunch, try figuring out the probability of picking an exactly correct bracket. The American Institute of Physics puts the odds at one in 9,223,372,036,854,775,808. That's one in 2 to the 63rd power. Thanks, combinatorics, for busting my bracket!

But Georgia Tech professor Joel Sokol thinks he has the secret to beating those odds, and it's called a Logistic Regression/Markov Chain. Didn't hear about it on PTI? The system uses scoreboard data from the regular season to pick likely winners on a neutral court, giving less weight to photo-finishes than to routs. Last year, it led him to a perfect Final Four, championship game, and tournament winner pick. Stay tuned to see how he'll fare this year.

You may now return to checking your bracket, which thankfully doesn't use up as many productive hours as you thought it did.

Old School

Is rap the ideal medium for spreading scientific knowledge? You be the judge:

Large Hadron Collider Rap Let the particles fly

Gregor Mendel Rap Rapping monks

Scientific Method Rap It all starts with a question

Chemistry Rap: (Gas) Laws of the Streets PV=nRT!

Respiration Rap Just breathe

Rapping Science

Kudos to John Tierney for finding this awesome rap on Evo Devo (the science of Evolutionary Developmental Biology):
Tierney Lab.

For those who haven't heard of Evo Devo before, this is the science that looks at how we and all the species on earth evolved by looking through the lens of development (i.e. how an animal grows up from an embryo). So by understanding how an embryo grows into its complex adult form, we can find clues in the animal's genes as to how new limbs and body function arise (e.g. by looking at what genes are turned on to make a limb, we get an idea of the pathway that evolved in order to make limbs).

Also note in the rap one of the rappers is wearing an old Toronto Blue Jays hat - my home team! (Though now living in Boston I am of course a Red Sox fan :)

Under the sea

I was starting to think this whole "spookfish" thing might be a hoax. A deep-sea fish with a see-through head and tubular eyes? These marine biologists think we'll swallow anything!

But now I see that the spookfish--a.k.a. barrelfish--is as real as you and me. How do I know? It's on YouTube!

Prepare for some aquatic weirdness.
