Setting stars reveal planetary secrets
Watching the stars set from the surface of the Earth may be a romantic pastime but when a spacecraft does it from orbit, it can reveal hidden details about a planet's atmosphere. view more (2007-11-06)
Experiment Demonstrates 110 Years of Sustainable Agriculture
A plot of land on the campus of Auburn University shows that 110 years of sustainable farming practices can produce similar cotton crops to those using other methods. view more (2008-09-30)
Atmospheric chemistry - air quality and climate
Air quality has improved dramatically over the past 50 years. Professor Mike Pilling, Head of Physical Chemistry at the University of Leeds, will reveal the latest about air quality research at the Festival of Science today. view more (2004-09-06)
Chemists forge a new form of iron
An international team of chemists has discovered a new and unexpected form of iron, a finding that adds to the fundamental understanding of an element that is among the most abundant on Earth and that, in nature, is an essential catalyst for life. view more (2006-06-02)
Eating cured meats frequently can lead to lower lung function and potential COPD
Frequent consumption of cured meats results in lower lung function test scores and increases the odds of developing chronic obstructive pulmonary disease (COPD), according to a large cross-sectional survey of adults in the U.S. view more (2007-04-16)
Caltech scientists predict greater longevity for planets with life
Roughly a billion years from now, the ever-increasing radiation from the sun will have heated Earth into inhabitability; the carbon dioxide in the atmosphere that serves as food for plant life will disappear, pulled out by the weathering of rocks; the oceans will evaporate; and all living things will disappear. view more (2009-06-15)
Berkeley Lab's Ultraclean Combustion Technology For Electricity Generation Fires Up in Hydrogen Tests
An experimental gas turbine simulator equipped with an ultralow-emissions combustion technology called LSI has been tested successfully using pure hydrogen as a fuel - a milestone that indicates a potential to help eliminate millions of tons of carbon dioxide and thousands of tons of NOx from power plants each year. view more (2007-08-03)
Scientists levitate diamond, lead and platinum
Scientists at The University of Nottingham have successfully levitated diamond and some of the heaviest elements, including lead and platinum. view more (2005-05-11)
Ethanol Production Could Jeopardize Soil Productivity
There is growing interest in using crop residues as the feedstock of choice for the production of cellulosic-based ethanol because of the more favorable energy output relative to grain-based ethanol. view more (2009-06-03)
Study of agricultural watersheds and carbon losses
Dissolved organic carbon (DOC) losses from tile drains are an underquantified portion of the terrestrial carbon cycle. view more (2009-06-22)
Mandate for biofuels production requires science-based policy and global perspective
In his State of the Union Address on January 23, 2007, President Bush stated that, in order to substantially lower foreign oil imports, "We must increase the supply of alternative fuels, by setting a mandatory fuels standard to require 35 billion gallons of renewable and alternative fuels in 2017." view more (2008-10-03)
Argonne breakthrough may revolutionize ethylene production
A new environmentally friendly technology created by scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory may revolutionize the production of the world's most commonly produced organic compound, ethylene. view more (2008-02-06)
UK Astronomers Survey Galactic Graveyard
An unprecedented source of planetary nebulae, the disk-like relics of elderly, dying stars, has been discovered in the southern part of our Milky Way galaxy. With about 1000 planetary nebulae found so far and many more still to be discovered, the number of aged stars in their death throes revealed by the new survey is rapidly overtaking the entire... view more...

A Zen discovery: Unrusted iron in ocean
Iron dust, the gold of the oceans and rarest nutrient for most marine life, can be washed down by rivers or blown out to sea or - a surprising new study finds - float up from the sea floor. view more (2009-02-09)
Single spinning nuclei in diamond offer a stable quantum computing building block
Surmounting several distinct hurdles to quantum computing, physicists at Harvard University have found that individual carbon-13 atoms in a diamond lattice can be manipulated with extraordinary precision to create stable quantum mechanical memory and a small quantum processor, also known as a quantum register, operating at room temperature. view more (2007-06-01)
Nitrous Oxide Emissions Respond Differently to No-Till Depending on the Soil Type
The practice of no-till has increased considerably during the past 20 yr. The absence of tillage coupled with the accumulation of crop residues at the soil surface modifies several soil properties but also influence nitrogen dynamics. view more (2008-10-23)
Spreading antibiotics in the soil affects microbial ecosystems
Antibiotics used extensively in intensive livestock production may be having an adverse effect on agricultural soil ecosystems. view more (2009-03-30)
NOAA study shows nitrous oxide now top ozone-depleting emission
Nitrous oxide has now become the largest ozone-depleting substance emitted through human activities, and is expected to remain the largest throughout the 21st century, NOAA scientists say in a new study. view more (2009-08-28)
Ceramic tubes could cut greenhouse gas emissions from power stations
Greenhouse gas emissions from power stations could be cut to almost zero by controlling the combustion process with tiny tubes made from an advanced ceramic material. view more (2007-08-03)
U-M researcher and colleagues predict large 2009 Gulf of Mexico 'dead zone'; Chesapeake Bay's oxygen-starved zone likely to shrink
University of Michigan aquatic ecologist Donald Scavia and his colleagues say this year's Gulf of Mexico "dead zone" could be one of the largest on record, continuing a decades-long trend that threatens the health of a half-billion-dollar fishery. view more (2009-06-19)
