While Darwin's 200th birthday (last February) was celebrated with gusto, I think it's equally (if not more) important to toast his decision to publish his 'dangerous idea' about evolution. This was something he struggled long and hard with - until one day a letter arrived in the mail that would force his hand.

Stuff! It's all around us. The metals, plastics, glass, fibers and other materials that make up our homes, our cars, our electronics, our everything! Most of the time we accept this stuff for what it is and don't give it another thought. But not David Pogue.
David is a New York Times
personal technology columnist and CBS news correspondent who wants to know,
just what is all of our stuff made of? How strong can materials get? On how
small of a scale can we work with them? How clean can we get our technology?
And how smart can a material become? From the first man to craft a tool using a
rock, to the future of robots so small they'll navigate your blood stream,
we'll be following David as he searches for the stories behind the materials
that make up our world in this four-part program set to air in the fall of
2010 winter of 2011.
I'm Dan Parsons, a production assistant on the Making Stuff crew. So far in production we've locked down the treatment for one of the four episodes, titled "Strong, Stronger, Strongest" and should have the second, "Small Smaller Smallest" complete soon. We've lined up some interesting adventures for our host including trips to a demolition derby, an active Navy aircraft carrier, a steel mill, a diamond cutter and to MIT for a slow-motion look at exactly how things break. There's still a long road ahead of us, so keep checking back as production continues for an inside look behind the production of Making Stuff!
Publicist's Note: MAKING STUFF: Stronger, Smaller, Cleaner, Smarter will premiere Wednesday, January 19, 2011 at 9pm ET/PT on PBS

When we last left LCROSS, in July, the spacecraft was speeding along its slingshot trajectory toward the moon. On October 8th, about 10 hours before impact, the satellite released Centaur--the white, cylindrical rocket stage in the image above--and nudged it into a collision course with the well of a crater on the moon's surface. The rest of the spacecraft followed about 10 minutes behind Centaur, ready to start taking data as soon as the initial collision kicked up enough dust to analyze.
The crash was less dramatic than hoped. Scientists originally predicted that the headlong impact could send plumes of material shooting up to 10 kilometers above the surface--a reaction that would be visible to telescopes across the country. But, perhaps because of the spongy nature of the moon's surface, the dust didn't spray much further than a single kilometer high. At first, the mainstream media deemed the mission a flop.
But in the months following that impact, NASA scientists sifted through the data and found that the plume, though smaller than anticipated, was hardly a disappointment. The results released last week show that plume contained at least 26 gallons of water. (None of that was water in the liquid form we're used to, since the lack of atmosphere on the moon causes solid ice to sublime directly into a gas.)
What does this mean? For one thing, the moon may be more viable as a way station in space than previously thought. If we can harvest and use the moon's water, either to sustain humans in space, or as the raw material for making hydrogen fuel, we might be able to use the moon as our stopping place and leapfrog on to other planets.
But, as our friend from Reading Rainbow used to say, you don't have to take my word for it.
Check out this podcast, in which David Levin talks to David Morrison of NASA's Lunar Science Institute and asks him to explain why we should bother going back to the moon.
Still not psyched about the new discovery?

Ever imagined reading your body temperature from contacts? It seems like this contact lens with built-in LEDs will beat out any fancy colored competitors.
