Washington, D.C. (September 14, 2010) -- Driven by rapid global industrialization, finite fossil fuel reserves, and the high cost of many alternative energy options, meeting the world's energy challenge may demand novel solutions. One potential solution has its roots in the ubiquitous industrial invention: the factory. Investigators at SUNY Binghamton's Center for Advanced Microelectronics Manufacturing (CAMM) -- the only center of its kind in the United States -- are giving factory production of solar energy cells a modern makeover. Their approach includes the use of ...

Lead-free piezoelectric materials of the future

2010-09-14
Washington, D.C. (September 14, 2010) -- Piezoelectric materials have fantastic properties: squeeze them and they generate an electrical field. And vice-versa, they contract or expand when jolted with an electrical pulse. With a name derived from the Greek word meaning to squeeze or press, the piezoelectric effect was just a curiosity after it was discovered in several crystals in 1880. But in 1917, a quartz piezoelectric crystal was at the heart of the world's first submarine-detecting sonar. Piezoelectric materials really took off after the 1950s, with the development ...

Improving crisis prediction, disaster control and damage reduction

2010-09-14
Washington, D.C. (September 14, 2010) -- Some disasters and crises are related to each other by more than just the common negative social value we assign to them. For example, earthquakes, homicide surges, magnetic storms, and the U.S. economic recession are all kindred of a sort, according to a theoretical framework presented in the journal CHAOS, which is published by the American Institute of Physics. The researchers who developed this framework contend that these four types of events share a precursory development pattern -- a specific change of scale in indicators ...

How do your crystals grow?

2010-09-14
Washington, D.C. (September 14, 2010) -- Because one of the main bottlenecks in determining the structure of protein molecules is producing good isolated single crystals, improved crystallization techniques would be useful in a wide range of genomics and pharmaceutical research. Research reported in The Journal of Chemical Physics uses fluorescence correlation spectroscopy (FCS) to investigate the processes at the surface of a growing crystal. By focusing a laser on the crystal surface and measuring the resulting fluorescence, FCS can resolve dimensions as small as a ...

2010-09-14
Leading international marine scientists are proposing radical changes in the governance of the world's oceans to rescue them from overfishing, pollution and other human impacts. Based on a successful experiment in Chile, the researchers say a new approach to marine tenure could help to reverse the maritime 'tragedy of the commons' which has led to the depletion of fish stocks worldwide. "Marine ecosystems are in decline around the world. New transformational changes in governance are urgently required to cope with overfishing, pollution, global changes, and other drivers ...

Study shows tranquil scenes have positive impact on brain

2010-09-14
Tranquil living environments can positively affect the human brain function, according to researchers at the University of Sheffield. The research, which was published in the journal NeuroImage, uses functional brain imaging to assess how the environment impacts upon our brain functions. The findings demonstrated that tranquil environmental scenes containing natural features, such as the sea, cause distinct brain areas to become 'connected' with one another whilst man-made environments, such as motorways, disrupt the brain connections. The research involved academics ...

Chandra finds evidence for stellar cannibalism

Chandra finds evidence for stellar cannibalism
2010-09-14
Evidence that a star has recently engulfed a companion star or a giant planet has been found using NASA's Chandra X-ray Observatory. The likely existence of such a "cannibal" star provides new insight into how stars and the planets around them may interact as they age. The star in question, known as BP Piscium (BP Psc), appears to be a more evolved version of our Sun, but with a dusty and gaseous disk surrounding it. A pair of jets several light years long blasting out of the system in opposite directions has also been seen in optical data. While the disk and jets ...

Why 'scientific consensus' fails to persuade

2010-09-14
Suppose a close friend who is trying to figure out the facts about climate change asks whether you think a scientist who has written a book on the topic is a knowledgeable and trustworthy expert. You see from the dust jacket that the author received a Ph.D. in a pertinent field from a major university, is on the faculty at another one, and is a member of the National Academy of Sciences. Would you advise your friend that the scientist seems like an "expert"? If you are like most people, the answer is likely to be, "it depends." What it depends on, a recent study found, ...

Women more likely than men to accept global warming

Women more likely than men to accept global warming
2010-09-14
EAST LANSING, Mich. — Women tend to believe the scientific consensus on global warming more than men, according to a study by a Michigan State University researcher. The findings, published in the September issue of the journal Population and Environment, challenge common perceptions that men are more scientifically literate, said sociologist Aaron M. McCright. "Men still claim they have a better understanding of global warming than women, even though women's beliefs align much more closely with the scientific consensus," said McCright, an associate professor with ...

Watercress may 'turn off' breast cancer signal

2010-09-14
The research, unveiled at a press conference today (14 September 2010), shows that the watercress compound is able to interfere with the function of a protein which plays a critical role in cancer development. As tumours develop they rapidly outgrow their existing blood supply so they send out signals which make surrounding normal tissues grow new blood vessels into the tumour which feed them oxygen and nutrients. The research, led by Professor Graham Packham of the University of Southampton, shows that the plant compound (called phenylethyl isothiocyanate) found ...

Researchers nationwide ask for new focus on 'sudden death' heart disorder

2010-09-14
(PHILADELPHIA) An abrupt, fatal heart attack in a young athlete on the playing field is a tragedy destined to repeat itself over and over until more is understood about hypertrophic cardiomyopathy (HCM), a genetic disorder that is the most common cause of sudden death in young people but which affects people of all ages. So says a task force of cardiologists and cardiac biologists, headed by Thomas L. Force, M.D., James C. Wilson Professor of Medicine at Thomas Jefferson University, in the September 14th online edition of the journal Circulation. Their special report ...
