Phytoplankton may stimulate uptake of CO2
...resee," said Hales. "This is a very expensive and uncertain way of going after an issue that is not fully understood. For example, in the process of gathering up iron and steaming out to sea, you would burn up more fossil fuel than you would compensate for in the result. Besides that, there's also the issue...Articles on remote sensing in ecology published in BioScience
...utgrowth of the US space program, Landsat faces an uncertain future. Next, Steven W. Running of the University of Montana and his associates describe how data now being generated by the Moderate Resolution Imaging Spectroradiometer sensor of the Earth Observing System are used to generate global assessments of...All ecosystems are equally productive under drought conditions
... but rather exacerbate it, making the world a more uncertain place, he said. "There's enhanced variability in ecosystem processes with increased variability in precipitation," Huxman said. He said the finding suggests that ecologists should be doing experiments to see how various types of ecos...Gene alteration points to longevity, thinness
...which has been shown to extend lifespan. They were uncertain of the gene's function, but suspected it was a transporter. "When you look at the protein coded by this gene you can guess what the gene does because transporters have certain structural features and the protein made by this gene has the same kind of...JCI Table of Contents, 15 July 2004

To investigate this process, Vincent Manganiello and colleagues, from the National Institutes of Health, created a mouse that is missing a gene for a protein whose function is to breakdown...Genetic clues found for common congenital brain disorder
...lker with ultrasound images is difficult and often uncertain until late in a pregnancy, usually after 20 weeks. Most parents, fearing mental retardation, choose to terminate the pregnancy if the disorder is diagnosed soon enough. A reliable genetic test could provide better information earlier and could be u...New Arizona State center brings science to policy on issues of water resources and urban growth
...ng region," added Gober. "Central Arizona faces an uncertain climate future due to global climate change, annual variability causing droughts and floods, and the urban heat island effect, which has raised nighttime summer low temperatures almost 10 degrees in the past 50 years."
