First off, the American Chemical Society (ACS) has declared ‘The Nano Song‘ a winner (in the People’s Choice and Critic’s Choice categories)  in their ACS Nanotation web community video contest ‘What is Nano?’.  If you haven’t seen the video yet, you can go here (scroll down).

Researchers at Sandia Labs are working to develop materials that change colour in the same that some fish can. Here’s how it works with the fish (from Nanowerk News here):

Certain fish species blend with their environment by changing color like chameleons. Their tiny motor proteins carry skin pigment crystals in their “tails” as they walk with their “feet” along the microtubule skeletons of cells to rearrange the animal’s color display.

The fish change colour as the environment around them changes. The researchers led by George Bachand are trying to enable synthetic or hybrid materials to do the same thing. Applications could be for military and/or fashion.

If you’re interested in the business end of nano, then there’s a webinar courtesy of the Australian Office of Nanotechnology coming up on April 29, 2009. NanoVentures Australia CEO, Peter Binks, will be talking about nanotechnology’s impact on global markets and industries.

Researchers at Pennsylvania State University (US) are honing in on a way to get hordes of microrobots (or nanobots) that have been introduced into the bloodstream to flock or swarm together so they can repair organs or deliver drugs to a specific target. I gather the problem has been  getting the machines to work together and the proposed solution is to use UV light. More details here.

Finally, some latebreaking news from Simon Fraser University (Vancouver, Canada). The university’s nano research facility, 4D Labs, has won funding (roughly $884, 000) from the federal government’s Western Economic Diversification agency to build a maskwritiing facility.  More about this tomorrow.
