A study published in the September 19 issue of Science shows that an innovative yet contentious fisheries management strategy called "catch shares" can reverse fisheries collapse. Where traditional "open access" fisheries have converted to catch shares, both fishermen and the oceans have benefited.
MADISON — Alternative energy doesn't always mean solar or wind power. In fact, the alternative fuels developed by University of Wisconsin-Madison chemical and biological engineering professor James Dumesic look a lot like the gasoline and diesel fuel used in vehicles today.
That's because the new fuels are identical at the molecular level to their petroleum-based counterparts. The only difference is where they come from.
Scientists at JILA, a joint institute of the National Instituteof Standards and Technology (NIST)and the University of Colorado atBoulder (CU-Boulder), have applied their expertise in ultracold atoms andlasers to produce the first high-density gas of ultracold molecules—twodifferent atoms bonded together—that are both stable and capable of stronginteractions.
The long-sought milestone in physics has potential applications in quantum computing, precisionmeasurement and designer chemistry.
Walnut trees respond to stress by producing significant amounts of a chemical form of aspirin, scientists have discovered.
The finding, by scientists at the National Center for Atmospheric Research (NCAR) in Boulder, Colo., opens up new avenues of research into the behavior of plants and their impacts on air quality, and also has the potential to give farmers an early warning signal about crops that are failing.
A team of scientists from the U.S. Department of Energy's Idaho National Laboratory earlier this month reached a major milestone with the successful production of hydrogen through High-Temperature Electrolysis (HTE).
The milestone was reached when the Integrated Laboratory Scale experiment started producing hydrogen at a rate of 5.6 cubic meters per hour.
The achievement was recognized at a media event in Idaho Falls Sept. 18.
"This is by far the biggest achievement we've had," said Carl Stoots, the experiment's principal investigator.
BOULDER--Plants in a forest respond to stress by producing significant amounts of a chemical form of aspirin, scientists have discovered. The finding, by scientists at the National Center for Atmospheric Research (NCAR), opens up new avenues of research into the behavior of plants and their impacts on air quality, and it also has the potential to give farmers an early warning signal about crops that are failing.
Primary carcinoma of the stomach is almost always adenocarcinoma or signet ring cell carcinoma and there are few reports of choriocarcinoma or neuroendocrine cell carcinoma. We report a patient with adenocarcinoma of the stomach combined with choriocarcinoma and neuroendocrine cell carcinoma. This is the first reported case of gastric cancer with these three pathological features.
RICHLAND, Wash. – Scientists have puzzled for years about why uranium contamination in groundwater continues to exceed drinking water standards in an area located at the south end of the Hanford Site. The Department of Energy wants answers to why the uranium persists.
RENO, Nev. – Sept. 17, 2008 – Plants and soils act like sponges for atmospheric carbon dioxide, but new research finds that one abnormally warm year can suppress the amount of carbon dioxide taken up by some grassland ecosystems for up to two years. The findings, which followed an unprecedented four-year study of sealed, 12-ton containerized grassland plots at DRI is the cover story in this week's issue (September 18) of the journal Nature.
CHAMPAIGN, Ill. — 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.
The Arctic sea ice cover appears to have reached its minimum extent for the year, the second-lowest extent recorded since satellite record-keeping began in 1979, according to the University of Colorado at Boulder's National Snow and Ice Data Center, or NSIDC.
While slightly above the record-low minimum set on Sept. 16, 2007, this season further reinforces the strong negative trend in summertime sea ice extent observed over the past 30 years, according to NSIDC researchers.

Queen's scientists are involved in two international projects aimed to protect Northern Ireland's agri-food industry from Bird Flu and African Swine Fever, a disease which kills pigs.
Working with colleagues from other EU-member states and the Far East in the FLUTEST project they are providing improved diagnosis and early warning systems for bird flu.
A giant perennial grass used as a biofuels source has a much longer growing season than corn, and researchers think they've found the secret of its success. Their findings offer a promising avenue for developing cold-tolerant corn, an advance that would significantly boost per-acre yields.
The new study, from researchers at University of Illinois, appears this month in Plant Physiology Preview.
COLUMBUS, Ohio – The recent dramatic melting and breakup of a few huge Greenland glaciers have fueled public concerns over the impact of global climate change, but that isn't the island's biggest problem.
A new study shows that the dozens of much smaller outflow glaciers dotting Greenland's coast together account for three times more loss from the island's ice sheet than the amount coming from their huge relatives.
