'Enlightened' Atoms Stage Nano-Riot Against Uniformity



When atoms in a crystal are struck by laser light, their electrons, excited by the light, typically begin moving back and forth together in a regular pattern, resembling nanoscale soldiers marching in a lockstep formation. But according to a new theory developed by Johns Hopkins researchers, under the right conditions these atoms will rebel against uniformity. Their electrons will begin moving apart and then joining together again repeatedly like lively swing partners on a dance floor.

For the first time researchers are getting a detailed look at the interior of human coronary arteries, using an optical imaging technique developed at the Wellman Center for Photomedicine at Massachusetts General Hospital. In their report in the journal JACC: Cardiovascular Imaging, the research team describes how optical frequency-domain imaging gives 3-D, microscopic views of significant segments of patients' coronary arteries, visualizing areas of inflammation and plaque deposits.

• Projects / Books for new child Makers - gift ideas
I'm thinking of purchasing/creating some gifts for a friends children. Their children are under 6 years old. My questions are as follows:

1) What is the youngest to start with electronic projects?

2) What books would you recommend for a parent who wants to involve their young child in learning projects/experiements? (I'm specifically referring to those for sale in the maker shed but any suggestions would be good.)

3) What projects/kits would you recommend for a parent who wants to involve their young child in learning projects/experiements? (I'm specifically referring to those for sale in the maker shed but any suggestions would be good.)

4) What warnings would you have for someone just starting out and working with children? (beyond the obvious safety gear, never take your eyes off them, etc.) I'm seeking advice on types of projects to avoid, duration/complexity of projects, etc.

• Parasite-resistant Peppers Green Alternatives To Chemical Pesticides
Root-knot nematodes are microscopic, omnipresent worms that cause major damage to horticultural and field crops in sub-tropical regions, resulting in significant financial losses to growers and gardeners. To combat these parasites without the use of chemical pesticides, scientists are focusing more research on developing new, parasite-resistant varieties of vegetables.
