Berkeley – Exposure to dirty air is linked to decreased function of a gene that appears to increase the severity of asthma in children, according to a joint study by researchers at Stanford University and the University of California, Berkeley.
While air pollution is known to be a source of immediate inflammation, this new study provides one of the first pieces of direct evidence that explains how some ambient air pollutants could have long-term effects.
Measuring a fuel cell's overall performance is relatively easy, but measuring its components individually as they work together is a challenge. That's because one of the best experimental techniques for investigating the details of an electrochemical device while it's operating is x-ray photoelectron spectroscopy (XPS). Traditional XPS works only in a vacuum, while fuel cells need gases under pressure to function.
Researchers at the Georgia Institute of Technology have developed a new "templated growth" technique for fabricating nanometer-scale graphene devices. The method addresses what had been a significant obstacle to the use of this promising material in future generations of high-performance electronic devices.
Phishing scams are making the leap from email to the world's voice systems, and a team of researchers in the Georgia Tech College of Computing has found a way to tag fraudulent calls with a digital "fingerprint" that will help separate legitimate calls from phone scams.
Optical gyroscopes, also known as rotation sensors, are widely used as a navigational tool in vehicles from ships to airplanes, measuring the rotation rates of a vehicle on three axes to evaluate its exact position and orientation. Prof. Koby Scheuer of Tel Aviv University's School of Physical Engineering is now scaling down this crucial sensing technology for use in smartphones, medical equipment and more futuristic technologies.
OAK RIDGE, Tenn., Oct. 5, 2010 -- By installing wireless sensors and replacing faulty traps along the 12 miles of steam lines at Oak Ridge National Laboratory, officials expect to save as much as $675,000 per year.
With 1,600 steam traps, which normally open slightly to discharge condensed steam with a negligible loss of live steam, the problem occurs when a trap fails and that failure goes undetected and unrepaired, said Teja Kuruganti, a member of the Computational Sciences and Engineering Division.
Diamonds adorning tiaras to anklets are treasures but these gemstones inside the body may prove priceless.
Two Case Western Reserve University researchers are building implants made of diamond and flexible polymer that are designed to identify chemical and electrical changes in the brain of patients suffering from neural disease, or to stimulate nerves and restore movement in the paralyzed.
A balloon angioplasty device that sucks up dangerous plaque debris could trigger a "paradigm shift" in how physicians treat peripheral artery disease, researchers write in the current issue of Endovascular Today.
"We will see a shift in how we treat lesions," write Dr. Robert Dieter of Loyola University Health System and Dr. Aravinda Nanjundappa of West Virginia University.
GRAND RAPIDS, MICH., Oct. 5, 2010 – Only about a third of American women are meeting their fruit and vegetable intake recommendations, which means they are likely missing out on potentially important breast and ovarian health benefits (1). Along with vitamins, minerals and fiber, fruits and vegetables contain a type of phytonutrient called carotenoids, which research suggests help support women's health including breast and ovarian health.

Today's Oct. 4 issue of the high-impact journal, Applied Physics Letters, contains a new electrofluidics design from the University of Cincinnati and start-up company Gamma Dynamics that promises to dramatically reshape the image capabilities of electronic devices.
EAST LANSING, Mich. — Fish oil – long encouraged by doctors as a supplement to support heart and joint health, among other benefits – induced severe colitis and colon cancer in mice in research led by Michigan State University and published this month in the journal Cancer Research.
Washington, D.C. (October 5, 2010) -- Carbon nanotubes -- long, hollow cylinders of carbon billionths of a meter in diameter -- have many potential uses in nanotechnology, optics, electronics, and many other fields. The exact properties of nanotubes depend on their structure, and scientists as yet have little control over that structure, which is determined during the initial formation -- or growth -- of the nanotubes. In fact, says chemical engineer and materials scientist Eray Aydil of the University of Minnesota, "we do not know precisely how the nanotubes grow."
