One small step for mankind is now a leap for averting natural and man-made disasters on earth.
The world will miss its agreed target to stem biodiversity loss by next year, according to experts convening in Cape Town for a landmark conference devoted to biodiversity science.
The National Institute of Standards and Technology (NIST) has unveiled a method for calibrating entire waveforms -- graphical shapes showing how electrical signals vary over time -- rather than just parts of waveforms as is current practice.
The anticipated sea-level rise associated with climate change, including increased storminess, over the next 100 years and the impact on the nation's low-lying coastal infrastructure is the focus of a new, interdisciplinary study led by geologists at The Florida State University <http://www.fsu.edu/>.
WASHINGTON -- Plumes of harmful air pollutants can be transported across oceans and continents -- from Asia to the United States and from the United States to Europe -- and have a negative impact on air quality far from their original sources, says a new report by the National Research Council.
BUENOS AIRES, ARGENTINA (23 September 2009) -- As climate change negotiators continue to skirt the role of agricultural land use in reducing greenhouse gas emissions, top scientists working on land management in the world's vast dry areas will gather this week in Buenos Aires, Argentina, determined to make the case that thwarting desertification in drylands is viable and also critical to the su
NAIROBI, KENYA (24 August 2009) -- Although agriculture, particularly in the developing world, is often associated with massive deforestation, scientists from the World Agroforestry Centre demonstrated today, in a study using detailed satellite imagery, that almost half of all farmed landscapes worldwide include significant tree cover.
(Washington, DC ? 08/18/09) -- Scientists from NRL's Space Science and Remote Sensing Divisions, in collaboration with researchers from the University of New Mexico (UNM) and the National Radio Astronomy Observatory (NRAO) located in Socorro, N.M., have generated the first scientific results from the Long Wavelength Demonstrator Array (LWDA).
More accurate global weather forecasts and a better understanding of climate change are in prospect thanks to a breakthrough by engineers at Queen's University Belfast's Institute of Electronics, Communications and Information Technology (ECIT).
Where the first Americans came from, when they arrived and how they got here is as lively a debate as ever, only most of the research to date has focused on dry land excavations. But, last summer's pivotal underwater exploration in the Gulf of Mexico led by Mercyhurst College archaeologist Dr.
In the last decade, Asian farmers have cleared tens of thousands of square miles of forests to accommodate the world's growing demand for palm oil, an increasingly popular food ingredient. Ancient peatlands have been drained and lush tropical forests have been cut down.
Flying twin-engine light aircraft the equivalent of several trips around the globe and establishing a network of seismic instruments across an area the size of Texas, a U.S.-led, international team of scientists has not only verified the existence of a mountain range that is suspected to have caused the massive East Antarctic Ice Sheet to form, but also has created a detailed picture of the rug
Lasers, already used for everything from price scanning at the supermarket to eye surgery, now are likely to dramatically change the construction, large-scale manufacturing, remote sensing and defense industries. A new National Institute of Standards and Technology (NIST) report* predicts ''tremendous'' applications for laser scanning devices, also known as LADARs (for Laser Detection and Ranging) and argues for a vigorous effort to create next-generation LADAR---a coffee-cup-size device with millimeter accuracy. The results, says study director William C. Stone, ''could be comparable to the advances achieved when computers were first matched with machinery.''
Two of the three largest impact craters on Earth have nearly the same size and structure, researchers say, but one was caused by a comet while the other was caused by an asteroid. These results could have implications for where scientists might look for evidence of primitive life on Mars.
