2 rockets set to launch from Poker Flat Research Range
Fairbanks, Alaska — Scientists from Virginia Tech and the University of Colorado are preparing to launch two NASA sounding rockets for two experiments at Poker Flat Research Range north of Fairbanks. The launch window for both experiments opens on…
No longer just a spectator, silicon oxide gets into the electronics action on computer chips
In the materials science equivalent of a football fan jumping onto the field and scoring a touchdown, scientists are documenting that one fundamental component of computer chips, long regarded as a passive bystander, can actually be made to act like…
UNH scientists help show potent GHG emissions are 3 times estimated levels
DURHAM, N.H. — In a study published December 20 in the Proceedings of the National Academy Sciences (PNAS), a team of researchers including University of New Hampshire scientists Wilfred Wollheim, William McDowell, and Jody Potter details findings…
Dodds contributes to new national study on nitrogen water pollution
MANHATTAN, KAN. — A Kansas State University professor is part of a national research team that discovered that streams and rivers produce three times more greenhouse gas emissions than estimated by the Intergovernmental Panel on Climate Change.
T…
Ocean acidification changes nitrogen cycling in world seas
Increasing acidity in the sea’s waters may fundamentally change how nitrogen is cycled in them, say marine scientists who published their findings in this week’s issue of the journal Proceedings of the National Academy of Sciences (PNAS).
Ni…
Waterways contribute to growth of potent greenhouse gas
EAST LANSING, Mich. — Nitrous oxide, a potent greenhouse gas, has increased by more than 20 percent over the last century, and nitrogen in waterways is fueling part of that growth, according to a Michigan State University study.
Based on this n…
New study focuses on nitrogen in waterways as cause of nitrous oxide in the atmosphere
Jake Beaulieu, a postdoctoral researcher the Environmental Protection Agency in Cincinnati, Ohio, who earned his doctorate at the University of Notre Dame, and Jennifer Tank, Galla Professor of Biological Sciences at the University, are lead authors…
Synchrotron study shows how nitric oxide kills
Nitric oxide is a toxic pollutant, but the human body also creates it and uses it to attack invading microbes and parasites. A new study by researchers at UC Davis, the Massachusetts Institute of Technology and the Japan Synchrotron Radiation Resear…
New ultra-clean nanowires have great potential
New ultra-clean nanowires produced at the Nano-Science Center, University of Copenhagen will have a central role in the development of new high-efficiency solar cells and electronics on a nanometer scale. PhD student Peter Krogstrup, Niels Bohr In…
Nanogenerators grow strong enough to power small conventional electronics
Blinking numbers on a liquid-crystal display (LCD) often indicate that a device’s clock needs resetting. But in the laboratory of Zhong Lin Wang at Georgia Tech, the blinking number on a small LCD signals the success of a five-year effort to po…
Inhaling nitric oxide eases pain crises in sickle cell patients
AUGUSTA, Ga. — Inhaling nitric oxide appears to safely and effectively reduce pain crises in adults with sickle cell disease, researchers report.
A study of 18 patients in Atlanta, Chicago and Detroit showed that the nine inhaling nitric oxide…
Powerful free radical causes lung damage from oxygen therapy
AUGUSTA, Ga. — The most toxic free radical appears responsible for much of the lung damage that can result from oxygen therapy in the critically ill or injured, Medical College of Georgia researchers report.
Within just a few days, ventilators…
Growing nanowires horizontally yields new benefit: ‘nano-LEDs’
While refining their novel method for making nanoscale wires, chemists at the National Institute of Standards and Technology (NIST) discovered an unexpected bonus—a new way to create nanowires that produce light similar to that from [...]
Nanocatalyst is a gas
HOUSTON — (Sept. 20, 2010) — A nanoparticle-based catalyst developed at Rice University may give that tiger in your tank a little more roar.
A new paper in the Journal of the American Chemical Society details a process by Rice Professor …
Researchers create new class of piezoelectric logic devices using zinc oxide nanowires
Researchers at the Georgia Institute of Technology have developed a new class of electronic logic device in which current is switched by an electric field generated by the application of mechanical strain to zinc oxide nanowires.
The devices, …
Silicon oxide circuits break barrier
Rice University scientists have created the first two-terminal memory chips that use only silicon, one of the most common substances on the planet, in a way that should be easily adaptable to nanoelectronic manufacturing techniques and promises to e…
Supplement produces a ‘striking’ endurance boost
Research from the University of Exeter has revealed taking a dietary supplement to boost nitric oxide in the body can significantly boost stamina during high-intensity exercise.
The study has important implications for athletes, as results sugge…
Nanotechnology may help overcome current limitations of gene therapy
Scientists from Northwestern University and Argonne National Laboratory have created a hybrid “nanodevice” composed of a “scaffolding” of titanium oxide nanocrystals attached with snippets of DNA that may one day be used to target defective genes that play a role in cancer, neurological disease and other conditions.
The titanium oxide nanocrystals, which are less than a few billionths of a meter in diameter and are the same material used in artificial hips and knees, may provide the ideal means of overcoming current limitations of gene therapy, such as adverse reactions to genetically modified viruses used as vehicles to deliver genes into cells.
