They include: High Throughput Structural Biology; Identification of Alternatively Spliced Genes in Arabidopsis; Development of NMR Tools for Metabolic Flux Maps of Soybean Seeds; A Transposable Element-based System for Site-specific Recombination in Arabidopsis.
A study of climate-induced evolutionary change in a California intertidal snail suggests that resource managers shouldn't focus exclusively on genetic diversity when developing conservation plans for protecting endangered or threatened species.
Three of the world's longest-running -- and dullest -- scientific experiments are still dripping, buzzing, and ticking away, decades and centuries after they were begun.
In work that could improve understanding of future climate change, University of Michigan researchers have documented a global-scale increase in oceanic biological productivity that occurred between about 6 million and 4 million years ago, during the late Miocene and early Pliocene epochs of geological history.
MetaPhore Pharmaceuticals, Inc. announced that it has received FDA approval of its Investigational New Drug application to conduct clinical trials in the U.S. to evaluate M40403, one of its enzyme mimetic compounds.
The Center for Water and Wetland Resources celebrates its dedication on June 1, but more than 30 projects - including studies of constructed wetland systems, surveys of amphibian populations and investigations of wild turkey behavior - are already under way.
A new Earth-orbiting monitor is providing the most complete view to date of the world's air pollution as it churns through the atmosphere, crossing continents and oceans. Scientists at the National Center for Atmospheric Research are making the world's first global maps of long-term lower-atmosphere pollution.
The National Science Foundation and the Environmental Protection Agency will host a workshop on June 4 in Washington, DC highlighting research that examines economic and other motivations for companies to go beyond environmental compliance requirements.
Established programs in lightweight materials, intelligent vehicle systems, and advanced diesels place the Department of Energy's Oak Ridge National Laboratory firmly in the cab when it comes to the 21st Century Truck Partnership.
A spacecraft that will explore one of the last frontiers in Earth's atmosphere is nearing launch. NASA's TIMED spacecraft was shipped from The Johns Hopkins University Applied Physics Laboratory, where it was designed and built, to Vandenberg Air Force Base. The spacecraft is currently scheduled to launch from Vandenberg's Western Range on Aug. 10, 2001.
Biologists have discovered a "channel" that allows key elements such as calcium and magnesium to enter living cells. The research provides new insight into the link between metabolic activity and a cell's ability to regulate its levels of key elements.
Estimates of deforestation that are significantly better than those currently used by the United Nations can be developed using data from NASA's new Terra satellite and a University of Maryland-developed method for mapping tree cover, say researchers in the Department of Geography and the Global Land Cover Facility at the university.
The world sounds very different to infants than it does to adults, sometimes being filled with a cacophony of sounds that makes it diffcult for babies to distinguish a single sound. That's because babies are generalists and hear all frequencies simultaneously, says a University of Washington researcher.
NASA's own 'Bionic Woman' is applying artificial intelligence to teach robots how to behave a little more like human explorers.
One of the world's largest and most malodorous flowers is about to bloom at the University of Wisconsin-Madison.
