More research needed to make good on biofuel promise, experts say
While cellulosic biofuels derived from grasses, crop residues and inedible plant parts have real potential to be more efficient and environmentally friendly than grain-based biofuels like corn ethanol, more research and science-based policies are needed to reap these benefits, says an international... view more (2008-10-06)

Commercial aquatic plants offer cost-effective method for treating wastewater
Nursery and greenhouse operations depend on the use of fertilizers, growth regulators, insecticides, and fungicides. Growers also rely on the use of soilless media, or substrate, in the production of container crops.   view more (2008-09-30)

Water table depth tied to droughts
Will there be another "dust bowl" in the Great Plains similar to the one that swept the region in the 1930s?   view more (2008-09-30)

MIT paves way to 'artificial nose'
MIT biological engineers have found a way to mass-produce smell receptors in the laboratory, an advance that paves the way for "artificial noses" to be created and used in a variety of settings.   view more (2008-09-30)

No oxygen in Eastern Mediterranean bottom-water
Research from Utrecht University shows that there is an organic-rich bed of sediment in the floor of the Eastern Mediterranean. This bed formed over a period of about 4000 years under oxygen-free bottom-water conditions.   view more (2008-09-29)

Looking for water on Mars
NASA's Phoenix Scout Lander reached Mars on May 25,, opened a soils lab, and started looking for water. Phoenix uses a robotic scoop arm to deliver regolith samples to the suite of instruments aboard the Lander--with one exception.   view more (2008-09-29)

Melting ice under pressure
The deep interior of Neptune, Uranus and Earth may contain some solid ice. Through first-principle molecular dynamics simulations, Lawrence Livermore National Laboratory scientists, together with University of California, Davis collaborators, used a two-phase approach to determine the melting... view more (2008-09-24)

Purifying nanorods: Big success with tiny cleanup
Chemists at Rice University have discovered a novel method to produce ultra-pure gold nanorods -- tiny, wand-like nanoparticles that are being studied in dozens of labs worldwide for applications as broad as diagnosing disease and improving electronic viewscreens.   view more (2008-09-23)

Is the Salad Bar Safe? Produce Concerns Linger after Summer Scares
Widespread reports had most people afraid to eat tomatoes this summer and when tomatoes were vindicated, eating peppers became a fear. A University of Missouri food safety expert says there is only so much that can be done to assure produce is safe to eat.   view more (2008-09-23)

Ocean floor geysers warm flowing sea water
An international team of earth scientists report movement of warmed sea water through the flat, Pacific Ocean floor off Costa Rica. The movement is greater than that off midocean volcanic ridges. The finding suggests possible marine life in a part of the ocean once considered barren.   view more (2008-09-23)

Modest CO2 cutbacks may be too little, too late for coral reefs
How much carbon dioxide is too much? According to United Nations Framework Convention on Climate Change (UNFCCC) greenhouse gases in the atmosphere need to be stabilized at levels low enough to "prevent dangerous anthropogenic interference with the climate system." But scientists have... view more (2008-09-23)

Pittsburgh researchers identify source of multipotent stem cells with broad regenerative potential
In a promising finding for the field of regenerative medicine, stem cell researchers at Children's Hospital of Pittsburgh of UPMC have identified a source of adult stem cells found on the walls of blood vessels with the unlimited potential to differentiate into human tissues such as bone, cartilage... view more (2008-09-22)

Nitrate Concentrations of Ground Water Increasing in Many Areas of the United States

Sowing a future for peas
New research from the John Innes Centre and the Central Science Laboratory could help breeders to develop pea varieties able to withstand drought stress and climate change.   view more (2008-09-17)

Simulations help explain fast water transport in nanotubes
By discovering the physical mechanism behind the rapid transport of water in carbon nanotubes, scientists at the University of Illinois have moved a step closer to ultra-efficient, next-generation nanofluidic devices for drug delivery, water purification and nano-manufacturing.    view more (2008-09-17)

Saltwater solution to save crops
Technology under development at the University of New South Wales could offer new hope to farmers in drought-affected and marginal areas by enabling crops to grow using salty groundwater.   view more (2008-09-12)

U.S. Air Force Technology Helps Scientists Understand Plant Root Function
The McClellan Nuclear Radiation Center (MNRC) in Sacramento, CA was developed by the U.S. Air Force to detect corrosion and defects in aircraft structure using an imaging technique called neutron radiography. This technique is currently helping soil scientists understand the function of plant roots... view more (2008-09-09)

Valley networks on Mars formed during long period of episodic flooding
A new study suggests that ancient features on the surface of Mars called valley networks were carved by recurrent floods during a long period when the martian climate may have been much like that of some arid or semiarid regions on Earth.   view more (2008-09-09)

Science paper examines role of aerosols in climate change
A group of scientists affiliated with the International Geosphere-Biosphere Programme (IGBP) have proposed a new framework to account more accurately for the effects of aerosols on precipitation in climate models.   view more (2008-09-08)

Living sensor can warn of arsenic pollution
Scientists studying arsenic pollution have discovered a living sensor that can spot contamination. They have also discovered new bacteria that can clean up arsenic spills even in previously untreatable cold areas, microbiologists heard today (Monday 8 September 2008) at the Society for General... view more (2008-09-08)

Dirty air brings rain -- then again, maybe not
An international team of scientists, headed by Prof. Daniel Rosenfeld of the Institute of Earth Sciences at the Hebrew University of Jerusalem, has come up with a surprising finding to the disputed issue of whether air pollution increases or decreases rainfall. The conclusion: both can be true,... view more (2008-09-08)

Evolving designer ecosystem sheds light on unintended consequences
Amidst the semi-arid stretches of Phoenix, a visitor might blink twice at the sight of a sailboat cutting across the horizon. Tempe Town Lake, on the northern edge of Arizona State University (ASU), is just one of a multitude of lakes, small ponds, canals and dams combining flood control, water... view more (2008-09-04)

Biological invasions increasing due to freshwater impoundments, says CU-Boulder study
The growing number of dams and other impoundments is increasing the number of invasive species and the speed at which they spread, putting natural lakes at risk, says a study led by the University of Colorado at Boulder.   view more (2008-09-03)

Complex ocean behavior studied with 'artificial upwelling'
A team of scientists is studying the complex ocean upwelling process by mimicking nature - pumping cold, nutrient-rich water from deep within the Pacific Ocean and releasing it into surface waters near Hawaii that lack the nitrogen and phosphorous necessary to support high biological production.   view more (2008-09-03)
