Consider the escape mechanism of the lowly tadpole. Sensing drought or a shrinking food supply in its home pond, the tadpole produces a hormone that accelerates its transformation into a toad or frog.
A scientific breakthrough that could eventually become as important as X-ray and radar technologies may soon make it possible to see images of diseased tissue, electric fields, plastic explosives hidden in a suitcase, and much more that is undetected by other imaging systems. Called real-time electro-optic terahertz sensing, the technology was invented under the leadership of Xi-Cheng Zhang, associate professor of physics at Rensselaer Polytechnic Institute.
The idea that problem drinkers can simply cut back instead of cutting themselves off is the premise behind, the Guided Self-Change Clinic at Nova Southeastern University.
Organizations use hazing because "induction-begets devotion." Research by Caroline Keating, professor of psychology at Colgate University in Hamilton, NY, shows that severe treatment of initiates seems to enhance their commitment to the group. Her research shows that the harsher the hazing, the more attractive and competent group members seem to the initiates and the more initiates conform to the group.

Based in the College of Veterinary Medicine, the institute will provide financial support for studies by Cornell-affiliated researchers and will bring to campus speakers on a range of animal-welfare topics.
Astronomers are having a difficult time explaining how a distant galaxy can emit gamma rays at extremely high energies. The galaxy, called Markarian 421, is challenging conventional astronomical theories of particl acceleration processes driven by black holes. The observations also indicate that the universe is not as opaque at these energies as previosuly thought.
The solution to the growing environmental problem of scrap tires may well be found on the football field - or a golf course or a well-worn yard. The U.S. Patent Office on April 22 will issue a patent to Michigan State University to use crumb rubber as a turf topdressing. MSU turfgrass researchers discovered that working tires into the soil -- after grinding them into crumbs -- solves a thorny disposal problem while improving grass and athletic fields that get a lot of wear and tear.

The pollution control system in the United States is fragmented and inefficient, targetting the wrong problems, and lacking in all kinds of information needed for effective decisionmaking, according to a report released today by Resources for the Future. The report describes and evaluates the nine major federal environmental laws, the administrative decisionmaking system at the Environmental Protection Agency, and the federal-state division of labor that are the main elements of U.S. environmental policy. It is based on a comprehensive three-year examination of the pollution regulatory system, the first systematic evaluation of the nation's pollution control efforts to date.
