Finding the Real Potential of No-Till Farming for Sequestering Carbon
The potential of no-tillage (NT) soils for increasing the soil organic carbon (SOC) pool must be critically and objectively assessed. Most of the previous studies about SOC accrual in NT soils have primarily focused on the surface layer (<20-cm soil depth), and not for the whole soil profile. The lack of adequate data on the SOC profile is a... view more... (2008-05-07)
The solution to a 7-decade mystery is crystal-clear to FSU chemist
A Florida State University researcher has helped solve a scientific mystery that stumped chemists for nearly seven decades. In so doing, his team's findings may lead to the development of more-powerful computer memories and lasers. view more (2007-10-22)
Satellite sniffs out chemical traces of atmospheric pollution
The recent Hague talks on global warming focused attention on the so-called greenhouse gases in our atmosphere. But these gases are only a part of the story. Mankind generates a wide variety of emissions that are changing the chemistry and composition of our planet~s atmosphere. Satellite monitoring is helping scientists to understand those... view more... (2000-12-15)
Sunburn alert: UVB does more damage to DNA than UVA
As bombs burst in air this July 4, chances are that sunburn will be the red glare that most folks see - and feel. But unfortunately, even when there is no burn, the effects of the sun's ultraviolet (UV) rays can have deadly consequences. view more (2008-07-01)
Peat and forests save permafrost from melting

The point of icicles
Contemplating some of nature's cool creations is always fun. Now a team of scientists from The University of Arizona in Tucson has figured out the physics of how drips of icy water can swell into the skinny spikes known as icicles. view more (2006-09-21)
U-M research: New plastic is strong as steel, transparent
By mimicking a brick-and-mortar molecular structure found in seashells, University of Michigan researchers created a composite plastic that's as strong as steel but lighter and transparent. view more (2007-10-05)
New Era for Norwegian Antarctic Research
The framework conditions for Norwegian research in Antarctica are completely changing. The Norwegian summer station, Troll, will be a year-round station, and the airstrip beside Troll will soon accommodate intercontinental flights. This will have enormous consequences for Norwegian research. From February 2005, year-round operations at the... view more... (2004-08-04)
Unexpectedly long-range effects in advanced magnetic devices
A tiny grid pattern has led materials scientists at the National Institute of Standards and Technology (NIST) and the Institute of Solid State Physics in Russia to an unexpected finding-the surprisingly strong and long-range effects of certain electromagnetic nanostructures used in data storage. view more (2009-07-02)
The End of the Line for Silicon Dioxide?
By means of computer simulations, scientists at the Technical Universities in Clausthal and Vienna are investigating new materials for even smaller and more efficient transistor generations. The smaller the transistors, the faster they can operate. As a result, faster and faster processors can also be designed. The function of a transistor... view more... (2003-12-23)
The man from Southampton-he says yes!
23 October 1998 How do farmers know when their tomatoes are perfect and just right for picking? Southampton researchers have harnessed the same technology used to print T-shirts to develop a simple, robust device that can be used in the field to indicate when fruit is ripe. John Atkinson, head of the University of Southampton's Thick Film Unit... view more... (1998-11-17)
Air quality in West going south
By mid-century, air quality throughout the Western United States will deteriorate, according to a new EPA-funded computer simulation by the Pacific Northwest National Laboratory. view more (2005-10-07)
New material lubricates itself
A highly durable and moreover self-lubricating material has seen the light of day at a thin film laboratory at Linköping University. It is an alloy of boron suboxide and yttrium, BOY, and was grown by the physicist Denis Music. The discovery is put forward in his doctoral dissertation. The element boron and its compounds have many interesting... view more... (2003-09-25)
Penn materials scientist finds plumber's wonderland on graphene
Engineers from the University of Pennsylvania, Sandia National Laboratories and Rice University have demonstrated the formation of interconnected carbon nanostructures on graphene substrate in a simple assembly process that involves heating few-layer graphene sheets to sublimation using electric current that may eventually lead to a new paradigm... view more...

New Technology To Help Early Skin Cancer Diagnosis
Computer scientists in the UK have invented a new technology to help doctors diagnose skin cancer while it is still in its early stages, greatly improving the chances of successful treatment. The work has been carried out by a team led by Dr Ela Claridge in the University of Birmingham's School of Computer Science. The Engineering and Physical... view more... (2000-04-11)
Northwest Atlantic Ocean ecosystems experiencing large climate-related changes
Ecosystems along the continental shelf waters of the Northwest Atlantic Ocean—from the Labrador Sea south of Greenland all the way to North Carolina—are experiencing large, rapid changes, report oceanographers funded by the National Science Foundation (NSF) in the Feb. 23, 2007, issue of the journal Science. view more (2007-02-26)
New 'finFET' promising for smaller transistors, more powerful chips
Purdue University researchers are making progress in developing a new type of transistor that uses a finlike structure instead of the conventional flat design, possibly enabling engineers to create faster and more compact circuits and computer chips. view more (2009-11-11)
Air pollutants from abroad a growing concern, says new report
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. view more (2009-09-30)
