Scientists at the University of Konstanz in Germany and the National Institute of Standards and Technology (NIST) in the United States have built the first optical frequency comb—a tool for precisely ...
Physics and Astronomy |'Like other countries, Canada's population is aging, and the implications of this demographic change need to be better understood from the perspective of blood supply' says Antonio Páez...
Studies and Analyses |Two scientists from the Max Planck Institute for Meteorology in Hamburg (MPI-M) and the American National Oceanic and Atmospheric Administration (NOAA) report in the journal Nature that the interactio...
Earth Sciences |The new method improves accuracy in calibrations of oscilloscopes, common test instruments that measure voltage in communications and electronics devices, and potentially could boost performance and s...
Power and Electrical Engineering |“Our hypothesis is that the historic storm record, which extends back only about 150 years, isn’t a reliable indicator of true storm frequency, but the long-term geologic record is,” said Joseph F. Do...
Earth Sciences |A heavy concentration of aerosols -- tiny airborne particles of soot, dust, sulfuric acid and organic matter -- can affect rainfall, air quality and the amount of solar radiation reaching the Earth...
Ecology, The Environment and Conservation |Scientists merged monthly total ozone data derived from the vertically downward-looking measurements of the GOME instrument on ESA’s ERS-2 satellite, SCIAMACHY on ESA’s Envisat and GOME-2 on the Europ...
Earth Sciences |A combination of small satellites can, with innovative methods, use the signals of the navigation satellite systems GPS and Galileo to significantly improve remote sensing of the System Earth. ...
Information Technology |For all new Earth observation missions, a crucial part of the development process, after defining and designing the instruments, is to assess the future performance of the sensors. In addition, the al...
Physics and Astronomy |Fish and some amphibians possess a unique sensory capability in the so-called lateral-line system. It allows them, in effect, to "touch" objects in their surroundings without direct physical...
Physics and Astronomy |The Members of the Interdisciplinary Committee of the World Cultural Council make this year’s Science award to Prof. Sir John Houghton for his leading contributions to environmental research, especial...
Awards Funding |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 ...
Studies and Analyses |That's because swampy mangrove forests – essential breeding grounds for fish and shellfish in these countries – are being destroyed by worsening pollution, encroaching real estate development, an...
Agricultural and Forestry Science |The measurements were obtained during field tests and calibration of two prototype antennas for the much larger Long Wavelength Array (LWA), which will eventually consist of nearly 13,000 similar ante...
Physics and Astronomy |Satellites have given oceanographers an insight into a remarkable phenomenon – a significant extension of the Leeuwin Current curling around the southern tip of Tasmania and reaching as far north as S...
