First Complete Sequence

Arabidopsis thaliana

Scientists Report First Complete DNA Sequence of Plant Chromosomes
Scientists involved in an international effort to sequence the entire genome of Arabidopsis thaliana reported the first complete DNA sequence of a plant chromosome in the December 16, 1999, issue of the journal Nature. The results provide new information about chromosome structure, evolution, intracellular signaling and disease resistance in plants. The research conducted by U.S. participants was funded in large part by the National Science Foundation (NSF), as well as the U.S. Department of Agriculture and U.S. Department of Energy.    More...

Computer & earthquake

Earthquake Network Intended to Help Save Lives and Money
A computer network linking experimentation facilities at universities across the country promises to change the face of earthquake research. The National Science Foundation (NSF) will make available to the entire earthquake engineering community monitoring and testing equipment, modeling capabilities and an integrated data repository by bringing multiple facilities under one "virtual roof." The Network for Earthquake Engineering Simulation will help meet the national need of reducing and mitigating the effects of earthquakes and make more efficient use of the government's investment in earthquake science and engineering.    More...

Microscopic Images of Bacteria from Lake Vostok.

Bacteria May Thrive in Antarctic Lake
Two separate investigations of ice drilled at Lake Vostok, a suspected body of subglacial water deep in the Antarctic interior, indicate that bacteria may live thousands of meters below the ice sheet. The findings by two National Science Foundation-funded researchers were published in the Dec. 10 issue of Science. Two research teams, led by David M. Karl from the University of Hawaii and John C. Priscu of Montana taken from roughly 3,600 meters (11,700 feet) below the surface -- about 120 meters (393 feet) above the interface of ice and suspected water. Both teams found bacteria in "accreted" ice, or ice believed to be refrozen lake water.    More...

Tiny Sensors Could Detect Patients' Signs
NSF-supported researchers at the University of Kentucky have created tiny, thin-film sensors that can help measure conditions such as pressure, temperature and viscosity inside the human body, holding promise for minimally invasive medical diagnostic techniques. The sensors can even analyze chemical information such as pH and carbon dioxide concentrations in the stomach.    More...
