How Tesla Batteries Will Force Home Wiring To Go Low Voltage

Slashdot - Thu, 28/05/2015 - 2:47pm
CIStud writes with a story at CEPro suggesting that solar power and home batteries like Tesla's PowerWall "will force the reinvention of home wiring from primarily AC high voltage to DC home-run low voltage to reduce power conversion loss," writing "To avoid the 20% to 40% power loss when converting from DC to AC, home wiring will have to convert to home-run low-voltage, and eventually eliminate the need for high-voltage 110V electrical wiring." As a former full-time Airstream dweller, I can attest to the importance of DC appliances when dealing with batteries.

Astronomy: Link between mergers and supermassive black holes with relativistic jets

Science Daily - Thu, 28/05/2015 - 2:41pm
In the most extensive survey of its kind ever conducted, a team of scientists have found an unambiguous link between the presence of supermassive black holes that power high-speed, radio-signal-emitting jets and the merger history of their host galaxies. The results lend significant weight to the case for jets being the result of merging black holes.

Study cites federal policy as key to primary care access and nurse practitioner workforce development

Science Daily - Thu, 28/05/2015 - 2:39pm
With demand for primary care expected to increase sharply over the next five years– due to passage of the Affordable Care Act (ACA), population growth and aging – the role of advanced-practice nurses or nurse practitioners (NPs) is also increasing. But a new study illustrates how federal policies influence the NP workforce and practice, and how misalignment of those policies with state mandates can affect workforce supply and patient access to care.

Treatment for genetically caused emphysema effective, experts say

Science Daily - Thu, 28/05/2015 - 2:39pm
A landmark clinical study provides convincing evidence that a frequently overlooked therapy for genetically-caused emphysema is effective and slows the progression of lung disease. Alpha-1 antitrypsin deficiency is an inherited disorder that can cause emphysema even without exposure to tobacco smoke.

Not making enough money? Check your attitude

Science Daily - Thu, 28/05/2015 - 2:39pm
Holding cynical beliefs about others may have a negative effect on your income according to research using survey data from the United States and Europe. The reviews looked at cynicism (as measured by responses to a questionnaire) in national surveys of Americans (1,146 and 497 participants respectively) and income level at a later date. In both studies, a high level of cynicism was associated with lower income.

New Technique To Develop Single-Molecule Diode

Slashdot - Thu, 28/05/2015 - 1:51pm
William Robinson writes: Under the direction of Latha Venkataraman, associate professor of applied physics at Columbia Engineering, researchers have designed a new technique to create a single-molecule diode, that has rectification ratio as high as 250, and 'ON' current as high as 0.1 microamps. The idea of creating a single-molecule diode was suggested by Arieh Aviram and Mark Ratner who theorized in 1974, which has been the 'holy grail' of molecular electronics ever since its inception to achieve further miniaturization, because single molecule represent the limit of miniaturization.

Roadside air can be more charged than under a high-voltage power line

Science Daily - Thu, 28/05/2015 - 1:26pm
More charged particles in urban environments come from motor vehicle emissions than anything else which makes living beside a busy road with lots of diesel-driven vehicles worse for your health than living under high voltage power lines, experts say.

A sight for sore eyes: Visually training medical students to better identify melanomas

Science Daily - Thu, 28/05/2015 - 1:26pm
New research is helping to improve the ability of medical students and health professionals to detect early forms of skin cancer. The study concludes that traditional teaching methods can be improved substantially by training health professionals to put a greater focus on the visual aspects of the task, as opposed to an emphasis on learning the physiology and anatomy of skin lesions.

Super-efficient light-based computers

Science Daily - Thu, 28/05/2015 - 12:42pm
Infrared light passes through silicon the way visible light passes through glass. Just as a prism bends visible light to reveal the rainbow, different silicon structures can bend infrared light in useful ways. It is theoretically possible to replace wires with silicon fibers. Why bother: to transmit lots more data while using lots less energy.

Have you ever caught yourself yawning right after someone else did? The same happens to budgies. Biologists have just noted that contagious yawning also occurs between members of a bird species. Contagious yawning was previously thought only to occur between humans, domestic dogs, chimpanzees and a type of rodent aptly called the high-yawning Sprague-Dawley rat.

Innovative components pave way for cheaper wind energy

Science Daily - Thu, 28/05/2015 - 12:38pm
Wind turbines began cropping up across the landscapes of Spain and Germany in the 1990s'. These two countries have the highest wind energy production in the EU. But according to the Global Wind Energy Council, the global installed power capacity in Europe -- which is 134,007 MW -- has been surpassed by Asia with 141,964 MW, at the end of 2014. The wind power industry is arguably the most mature -- and fastest developing -- among renewable energies. But, there is still considerable room for improvement to compete with other sources of electricity.
