NOON - CLAM SHELL

USDA researchers have used wheat to make "clamshell" sandwich containers that are more environmentally friendly than the old polystyrene clamshells and keep food warmer than the cardboard containers now in vogue. The research was presented in San Diego at the national meeting of the American Chemical Society.

2 p.m. - CONSTRUCTING A SILICON CHIP FOR LIVER CELLS

Researchers at the University of California, San Diego will describe their development of a porous silicon chip, containing wells similar to a muffin tin, on which they have successfully grown liver cells. These notoriously fickle cells are difficult to grow outside of the body. The achievement by an interdisciplinary team headed by chemistry professor Michael Sailor and bioengineering professor Sangeeta Bhatia could pave the way for the development of new treatments for liver disease, new ways to test the toxicity of drugs on liver cells and eventually an artificial liver. Sailor will also describe how he is using the same porous silicon technology to construct "nanosculptures" with hundreds of trillions of nanometer-zided dots etched silicon chips.
