Novel freezer cuts energy demand

Article Abstract:

Latham, NY-based InterCool Energy Corp. has designed a prototype supermarket freezer that has the potential to provide a more energy-effecient operation using nonozone-depleting refrigerant gases. The system's cost should be no more than currant systems. Coinventor Boris Yudin says that the new system features "advanced subcooling". A refrigerant that goes through a phase change from a liquid to a gas at a low temperature is incorporated in regrigerators and freezers causing them to generate cold temperatures.

Glowing sensors highlight contamination

Article Abstract:

DuPont Co. and the University of Delaware, Newark, DE have developed inexpensive sensors that are able to rapidly detect a key toxin's presence in poultry feed. The sensors are made by grafting genes that glow in the presence of toxic chemicals to the common E. coli bacteria. The sensors luminesce in response to DNA damage and other intercellular changes caused by environmental stresses rather than responding to the chemistry of a particular chemical.

Attacking beach erosion

Article Abstract:

The United States Army Corp of Engineers is studying beach erosion along the beach at the Field Research Facility in Duck, North Carolina, where techniques and insights are being developed along with technology, such as the Surveying Wide Area Shorelines (SWASH) souped-up dune buggy and the Coastal Research Amphibious Buggy (CRAB), a 35 feet tall submersible wheeled tripod.
