Here’s a robot that was designed to mimic the subtle and intricate movements of the human face and lips.

Impressive strides in animatronic devices, but still creepy in my book.

Here’s an interesting snippet from Malcom Gladwell’s upcoming book Outliers: The Story of Success:

This idea — that excellence at a complex task requires a critical, minimum level of practice — surfaces again and again in studies of expertise. In fact, researchers have settled on what they believe is a magic number for true expertise: 10,000 hours.

I’ve also read that number about three years ago in one of my issues of Scientific American, and I suppose that study – as well as many others – has helped the research community settle on the figure.

LA’s Ivanhoe Reservoir contains millions of gallons of drinking water for LA residents.  In the summer, however, problem presents itself: the water can potentially become contaminated with bromate (depending on daily outbound flow rates, one would presume), which is a natural reaction between solar light, chlorine (a treatment chemical) and naturally-occurring bromide.

Seeing how chlorine is a necessary treatment additive and the bromide is a natural element within the water, Ivanhoe officials got creative and decided to keep sunlight away from the water by dropping over 3 million black spheres (called bird balls) into the reservoir.  This effectively created an opaque layer atop the water that serves as a solar shield.  Problem solved.  Creative, yes?

Check out a video of the action here.

But allow me to think out loud for a second: Ivanhoe is preventing the formation of a carcinogen by interrupting the photochemical reaction that forms bromate, the threat in question.  But is anyone thinking about the potential toxicity of millions of plastic balls leaching into the drinking water supply, especially millions of black balls that take the beating of the LA sun all summer?  To me, this seems like you could be trading one problem for another.
