Researchers discover a new parasitic wasp that attacks caterpillars harming citrus trees, offering an alternative to chemical pesticides. The discovery has economic potential for the US orange juice industry.
Wake vortices, created by large commercial aircraft, will be studied at Baltimore Washington International Airport (BWI) to develop a reliable detection system. The system aims to increase airport safety by providing controllers with observed vortex location and intensity information.
The Next Generation Project aims to refloat the US environmental policy debate with fresh thinking and new directions. A comprehensive compendium of ideas will be released at a workshop in Yale Law School, contributing to this fall's state and federal election campaigns.
Cornell materials scientists have created arrays of atomically flat silicon surfaces, eliminating atomic steps and overcoming a major hurdle in miniaturization. The technique involves creating a grid of ridges on the surface and forcing atomic steps into them, resulting in step-free regions.
A Cincinnati bridge has become a national test site for researchers seeking better ways to monitor the nation's highways. The bridge's design is similar to tens of thousands of other bridges still in use, making it an ideal test site. It was found that daily temperature changes can be just as devastating as heavy traffic loads.
