Understanding the genetic causes of spina bifida is a research objective of James F. Martin, an assistant professor of medical biochemistry and genetics at Texas A&M University's Institute of Biosciences and Technology. Spina bifida is a severe birth defect in which the spinal canal fails to fuse. There is no treatment for the resulting spinal cord damage.
Sandia National Laboratories has joined the effort to rid the planet of what some people have called its worst form of pollution -- land mines. SandiaÃs work in land-mine detection and demining ranges from chemical sensing and backscattered x-ray technologies, to laying down quick-hardening foam to clear a path for military vehicles and developing robotic vehicles that can be used as platforms to support the technologies.

Rates of atmospheric mercury deposition in Maine appear to have reached a peak in the early to mid-1970s and to have declined significantly by 1982, according to a report by University of Maine geologists published in the December issue of the journal Water, Air and Soil Pollution (v. 100: 271-186, 1997). Stephen A. Norton, Gordon C. Evans and Steve Kahl of the UMaine Department of Geological Sciences used archived cores from Sargent Mountain Pond and Big Heath in Acadia National Park on Mt. Desert Island to determine historical trends in mercury deposition from the atmosphere to the Maine landscape. The cores were collected in 1982 and 1983.
