Line Between Quantum And Classical Worlds Is At Scale Of Hydrogen Mole
Where do the realms of quantum mechanics and classical physics begin to overlap? It's a long-argued question of philosophical interest and practical importance. Now the world's smallest double slit experiment, performed at Lawrence Berkeley National Laboratory's Advanced Light Source and using as "slits"the two proton nuclei of a hydrogen molecule, has shown that quantum particles start behaving in a classical way on a scale as small as a single hydrogen molecule. New Record For Brightness Of Quantum Dots Set
By placing quantum dots on a specially designed photonic crystal, researchers have demonstrated enhanced fluorescence intensity by a factor of up to 108. Potential applications include high-brightness light-emitting diodes, optical switches and personalized, high-sensitivity biosensors. Secret History of the Credit Card
Companion to a Public Broadcasting Service (PBS) program in which Frontline and The New York Times "join forces to investigate an industry few Americans fully understand. ... [C]orrespondent Lowell Bergman uncovers the techniques used by the industry to earn record profits and get consumers to take on more debt."The site features the full program, interviews, facts for credit card users, and related articles. Also includes a teacher's guide. Increase In Atmospheric Moisture Tied To Human Activities
Observations and climate model results confirm that human-induced warming of the planet is having a pronounced effect on the atmosphere's total moisture content. The water vapor feedback mechanism works in the following way: as the atmosphere warms due to human-caused increases in carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons, water vapor increases, trapping more heat in the atmosphere, which in turn causes a further increase in water vapor. 80 Years of Robots in Hollywood
This article highlights films that have featured robots, starting with Fritz Lang's 1927 "Metropolis,"and including "The Stepford Wives,""Star Wars,""Alien,""Blade Runner,"and others. It also provides links to three other articles related to the 2007 film "Transformers."From Time Magazine. High Levels Of Daily Stress May Result In Lower Risk Of Breast Cancer
High levels of daily stress appear to result in a lower risk of developing breast cancer for the first time, says a study in this week's British Medical Journal. But high stress may put women at risk of other serious illnesses warn the researchers, a team from Denmark.But high stress may put women at risk of other serious illnesses warn the researchers, a team from Denmark. Body Composition Device Facilitates Infant Studies
The accuracy of a new machine for estimating the body composition of infants has been demonstrated in a two-year study by scientists at the U.S. Department of Agriculture (USDA)-funded Children's Nutrition Research Center (CNRC) in Houston, Texas. Nutrition researcher Ken Ellis at CNRC oversaw testing of the device--an infant-sized, air-displacement plethysmograph called the PEA POD Infant Body Composition System. Computer Aided Detection Plus MDCT Useful In Finding Lung Nodules
Computer-aided detection combined with MDCT improves radiologists'ability to detect solid lung nodules early enough for them to be treated without increasing interpretation time according to a recent study. Cell Phones Heed Call of the Wild
Tired of the computerized beeps of cheesy pop songs every time your cell phone rings? Animal mating calls, bird song and roars will soon give your phone a touch of the great outdoors. By Katie Dean. AnnualCreditReport.com
