How trees manage water in arid environments
The summer of 2006 was the second warmest in the continental United States since records began in 1895, according to the National Climatic Data Center. Moderate to extreme drought conditions were evident in about 40 percent of the country.   view more (2007-01-05)

Arctic heat wave stuns climate change researchers
Unprecedented warm temperatures in the High Arctic this past summer were so extreme that researchers with a Queen's University-led climate change project have begun revising their forecasts.   view more (2007-09-27)

New climate research reveals growing risk of water shortages and flooding in California
If the world continues to burn greenhouse gases, California may have an increased risk of winter floods and summer water shortages, even within the same year. This scenario may be more severe in future El Ni√ħo years.   view more (2006-02-08)

Bacteria can help predict ocean change
Every creature has its place and role in the oceans - even the smallest microbe, according to a new study that may lead to more accurate models of ocean change.   view more (2006-08-15)

Yes, Virginia, some snowflakes can look the same!
Snowflakes are one of the most recognizable and endearing symbols of winter. Their intricate shapes have been the inspiration for Christmas ornaments, jewelry and U.S. postage stamps. They are the subject of song, school projects and even scientific investigation, including a possible impact on... view more (2006-12-13)

Rehydrate - your RNA needs it
Water, that molecule-of-all-trades, is famous for its roles in shaping the Earth, sustaining living creatures and serving as a universal solvent.   view more (2006-08-23)

Hidden sponges determine coral reef's nutrient cycle
Marine organisms hidden in caves, such as sponges, play an extremely important role in the nutrient cycle of coral reefs.   view more (2005-09-15)

NASA images, White Sands features support a wetter Mars
NASA's announcement yesterday of evidence that water still flows on Mars, at least in brief spurts, demonstrates that the view of Mars as a very dry planet should be reevaluated, says Dawn Sumner, professor of geology at UC Davis. Recent work from by Sumner and graduate student Greg Chavdarian also... view more (2006-12-08)

Agriculture of Conservation proves to be best for cereal crops in Navarre
The application of conservation agriculture techniques to cereal crops in the semiarid zones of Navarre-57% of the surface area given over to crop cultivation in Navarre, is most profitable for conventional agriculture and improves the quality of the soil, apart from contributing to the... view more (2005-11-29)

Unique weather radar to investigate snowfall
The Department of Physical Sciences at the University of Helsinki has acquired a state-of-the-art polarimetric weather radar.   view more (2006-03-20)

World shark attacks dipped in 2005, part of long-term trend
Assertive and even aggressive human behavior could explain why shark attacks worldwide dipped last year, continuing a five-year downward trend in close encounters with the oceanic predators.   view more (2006-02-14)

Icy Jupiter Moon Throws a Curve Ball at Formation Theories
Scientists studying data from NASA's Galileo spacecraft have found that Jupiter's moon Amalthea is a pile of icy rubble less dense than water. Scientists expected moons closer to the planet to be rocky and not icy. The finding shakes up long-held theories of how moons form around giant planets.   view more (2005-06-01)

Global warming could halt ocean circulation, with harmful results
Absent any climate policy, scientists have found a 70 percent chance of shutting down the thermohaline circulation in the North Atlantic Ocean over the next 200 years, with a 45 percent probability of this occurring in this century.   view more (2005-12-08)

Shark attack worries? Driving to the beach is more deadly

NJIT professor discovers better way to desalinate water
Chemical engineer Kamalesh Sirkar, PhD, a distinguished professor at New Jersey Institute of Technology (NJIT) and an expert in membrane separation technology, is leading a team of researchers to develop a breakthrough method to desalinate water.   view more (2006-02-10)

Flood-plagued York threatened by drying out
York's world-renowned archaeological remains are in danger - of drying out. The problem also threatens to cause roads to buckle, sewers collapse and subterranean gases leak into the air, unless a team from Leeds geography department can discover the effect of flood defences and new building in and... view more (2004-02-23)

Swimming with dolphins can alleviate depression
Swimming with dolphins is an effective treatment for mild to moderate depression, say researchers in this week's BMJ.   view more (2005-11-28)

Measuring water from space
Observations from satellites now allow scientists to monitor changes to water levels in the sea, in rivers and lakes, in ice sheets and even under the ground. As the climate changes, this information will be crucial for monitoring its effects and predicting future impacts in different regions.   view more (2008-11-13)

North Sea efficient sink for carbon dioxide
The measured annual increase in the concentration of carbon dioxide (CO2) in the atmosphere is only 60 percent of the annual emissions from fossil fuels.   view more (2005-10-11)

NASA Scientists Detect Spectrum of Planets Orbiting Other Stars
For the first time, scientists at Goddard have obtained a spectrum, or molecular fingerprint, of a planet orbiting another star. Using spectroscopy, scientists were able to identify silicon dust in clouds on a gas-giant planet called HD 209458b. That planet is located 150 light years from Earth.   view more (2007-02-23)

The moon's south pole: Very high resolution, radar images find rocks abundant, but no ice sheets
Using the highest resolution radar-signal images ever made of the moon - images from the National Science Foundation's (NSF) Arecibo Telescope in Arecibo, P.R., and the NSF's Robert C. Byrd Telescope in Green Bank, W.Va. - planetary astronomers have found no evidence for ice in craters at the lunar... view more (2006-10-19)

Even a Mile of Forest Makes a Difference in Water Quality
