LED's efficiency exceeds 100% March 5, 2012 by Lisa Zyga Enlarge An LED’s power conversion (wall-plug) efficiency varies inversely with its optical output power. Wall-plug efficiency can exceed 100%, the unity efficiency, at low applied voltages and high temperatures. Image credit: Santhanam, et al. ©2012 American Physical Society (PhysOrg.com) -- For the first time, researchers have demonstrated that an LED can emit more optical power than the electrical power it consumes. Although scientifically intriguing, the results won’t immediately result in ultra- efficient commercial LEDs since the demonstration works only for LEDs with very low input power that produce very ...

Gasoline Worse Than Diesel When It Comes to Some Types of Air Pollution
Post Date: 2012-03-04 00:25:31 by Tatarewicz
0 Comments
ScienceDaily (Mar. 2, 2012) — The exhaust fumes from gasoline vehicles contribute more to the production of a specific type of air pollution -- secondary organic aerosols (SOA) -- than those from diesel vehicles, according to a new study by scientists from the Cooperative Institute for Research in Environmental Sciences (CIRES), NOAA's Earth System Research Laboratory (ESRL) and other colleagues. "The surprising result we found was that it wasn't diesel engines that were contributing the most to the organic aerosols in LA," said CIRES research scientist Roya Bahreini, who led the study and also works at NOAA's ESRL. "This was contrary to what the ...

ScienceDaily (Mar. 2, 2012) — Millions of people suffer from Parkinson's disease, a disorder of the nervous system that affects movement and worsens over time. As the world's population ages, it's estimated that the number of people with the disease will rise sharply. Yet despite several effective therapies that treat Parkinson's symptoms, nothing slows its progression. While it's not known what exactly causes the disease, evidence points to one particular culprit: a protein called ±-synuclein. The protein, which has been found to be common to all patients with Parkinson's, is thought to be a pathway to the disease when it binds together in ...

Potato spotter The system is taught by a human expert to spot damaged and diseased potatoes A "learning" computer system that sorts potatoes has been built using off-the-shelf technology by researchers at the University of Lincoln's Robotics Lab. The robot blemish spotter can reliably identify diseases such as silver scurf and common scab, researchers said. The test system uses computer kit not dissimilar from systems many gamers will have in their homes. The UK potato industry is worth about £3.5bn, but much of the sorting of produce is still done by hand. TADD - or the Trainable Anomaly Detection and Diagnosis system - is able to "detect, identify and ...

*THIS ARTICLE IS NOT ABOUT ZIONIST BANKERS* The giant dinosaurs that roamed the world some 150 million years ago shared the planet with equally daunting parasites: blood-gobbling fleas that were up two centimetres (almost an inch) long. So say Chinese and French palaeontologists, who have pored over nine extraordinary fossils unearthed from Inner Mongolia and Liaoning province. The ancient fleas measured just over 20mmm (0.82 inches) long for females, and nearly 15mm (0.6 inches) in males, compared to a maximum of 5mm (0.2 inch) for today's fleas. The dino-era fleas were wingless and, unlike their counterparts today, could not jump and had comparatively small mouths, says the ...

DARPA's $40K 'quest' tests social media's ability to help in emergency By Kevin McCaney Feb 27, 2012 Can social media really spread the word during a crisis and help emergency crews find the resources they need to improve their response to it? The Defense Advanced Research Projects Agency is putting up $40,000 to find out, and the game is afoot. The agency is running the CLIQR Quest Challenge (the acronym comes from Cash for Locating and Identifying Quick Response codes), asking participants to use their online presence to locate and identify QR codes that represent various assets responders might need. The first person who identifies the QR codes can win up to $40,000. ...
Bestselling Author Charles Murray Has A Controversial Suggestion For Reducing Class Divisions

I really liked Tierney and Baumeister's book Willpower. Their argument is that willpower is a very useful skill, one that like a muscle tires when used, but can be strengthened through repetition. We should all practice daily acts of self-control to become more productive. Charles Murray's latest book Coming Apart addresses the same theme, noting that society is splitting up into classes based on their abilities, which are highly driven by bourgeois values. Over the past 50 years, the working class have lost their industriousness, honesty, religion, and respect for marriage, and he presents a bunch of data to bolster this argument (eg, less than 5% of college educated white women ...

ScienceDaily (Feb. 27, 2012) — Cells use various methods to break down and recycle worn-out components -- autophagy is one of them. In the dissertation she will be defending at Umeå University in Sweden, Karin Håberg shows that the protein SNX18 is necessary for cells to be able to perform autophagy. In animal experiments on both simple organisms like fruit flies and in more complex animals like mice, researchers have seen that stimulating autophagy leads to increased longevity. It is still unclear whether these results are directly translatable to humans. However, there are theories that calorie restriction, which is a relatively well-established way of increasing ...

LONDON, Feb. 27, 2012 (Reuters) — Who wants to live forever? Some flatworms do, even if it means no sex. British scientists have found that a species of flatworm can overcome the process of ageing to become potentially immortal and say their work sheds light on possibilities of alleviating ageing and age-related characteristics in human cells. In a study published in the Proceedings of the National Academy of Sciences journal on Monday the researchers found that the flatworms, known as planarian worms, can continuously maintain the length of a crucial part of their DNA, known as telomeres, during regeneration. "Our data satisfy one of the predictions about what it would take ...

BEIJING, Feb. 27 (Xinhuanet) -- Stem cells extracted from human ovaries can be used to generate egg cells to be applied in infertility treatment, said researchers at Massachusetts General Hospital as quoted by media reports Monday. Lead researcher Dr. Jonathan Tilly said: "The discovery of oocyte precursor cells in adult human ovaries, coupled with the fact that these cells share the same characteristic features of their mouse counterparts that produce fully functional eggs, opens the door for development of unprecedented technologies to overcome infertility in women and perhaps even delay the timing of ovarian failure." According to the research team, a rooted belief is that ...

Defining PseudoSkeptics vs. True Skeptics: Behaviors and Tactics According to Webster's Revised Unabridged Dictionary, a skeptic is: "One who is yet undecided as to what is true; one who is looking or inquiring for what is true; an inquirer after facts or reasons." Pyrrho, the founder of "Skepticism", intended for it to be about open inquiry and suspension of judgment. http://en.wikipedia.org/wiki/Skeptic “In classical philosophy, skepticism refers to the teachings and the traits of the 'Skeptikoi', a school of philosophers of whom it was said that they 'asserted nothing but only opined.'

WELLINGTON, Feb. 22 (Xinhua) -- The clouds might be fighting back against global climate change, said scientists in New Zealand Wednesday. The research from the University of Auckland on changes in cloud height in the decade to 2010 has provided the first hint of a cooling mechanism that could be in play in the Earth's climate. The analysis of data from the NASA Terra satellite showed an overall trend of decreasing cloud height of about 1 percent, or 30 to 40 meters, over the decade, said a statement from the university. Most of the reduction was due to fewer clouds occurring at very high altitudes. "This is the first time we have been able to accurately measure changes in ...
Light speed travel - Was Einstein wrong - or was the cable loose?

LONDON/GENEVA, Feb. 22, 2012 (Reuters) — The world of science was upended last year when an experiment appeared to show one of Einstein's fundamental theories was wrong - but now the lab behind it says the result could have been caused by a loose cable. Physicists at the CERN laboratory near Geneva appeared to contradict Albert Einstein last year when they reported that sub-atomic particles called neutrinos could travel fractions of a second faster than light. Einstein had said nothing could ever travel faster than light, and doing so would be like traveling back in time. But James Gillies, a spokesman for CERN, said Wednesday the lab's startling result was now in doubt. ...
Genetic Maker of Men Is Diminished but Holding Its Ground

Men, or at least male biologists, have long been alarmed that their tiny Y chromosome, once the same size as its buxom partner, the X, will continue to wither away until it simply vanishes. The male sex would then become extinct, they fear, leaving women to invent some virgin-birth method of reproduction and propagate a sexless species. The fear is not without serious basis: The Y and X chromosomes once shared some 800 genes in common, but now, after shedding genes furiously, the Y carries just 19 of its ancestral genes, as well as the male-determining gene that is its raison d’être. So much DNA has been lost that the chromosome is a fraction of its original size. But there ...

This morning when attempting to access a web page I noticed a little box in the bottom left hand corner that said something to the effect of "reading Google Analytics or something to that effect. So after researching it I found that it is a free service that Google provides to web sites so those websites can track information about their users. OK, I have no problem with that per say. I can understand why that would be useful to an e-commerce site. However, Google also receives this information and stores it in their database. I DO have a problem with that. So, after investigating how to get my browser to quit giving this info to Google, I found that there is an add-on for Firefox ...

It was an Ice Age squirrel's treasure chamber, a burrow containing fruit and seeds that had been stuck in the Siberian permafrost for over 30,000 years. Svetlana Yashina of the Institute of Cell Biophysics of the Russian Academy Of Sciences, who led the regeneration effort, said the revived plant looked very similar to its modern version, which still grows in the same area in northeastern Siberia. "It's a very viable plant, and it adapts really well," she told The Associated Press in a telephone interview from the Russian town of Pushchino where her lab is located. She voiced hope the team could continue its work and regenerate more plant species. The Russians research ...

Should scientists be allowed to create extremely aggressive and highly infectious influenza viruses? Dutch virologists have done it and, in the process, triggered a fierce debate over the risks of bioterrorism and the potential release of deadly viruses. Info The 17th floor of the Erasmus Medical Center in the Dutch city of Rotterdam certainly doesn't look like the kind of place that could pose a threat to global security. A disco ball hangs from the ceiling in the hallway in front of the elevators, and a bar with a golden beer tap stands in the corner of the conference room. Everything in this 1960s high-rise building evokes the charm of student life, including the door to Room ...
Lab-grown meat is first step to artificial hamburger

Dutch scientists have used stem cells to create strips of muscle tissue with the aim of producing the first lab-grown hamburger later this year. The aim of the research is to develop a more efficient way of producing meat than rearing animals. At a major science meeting in Canada, Prof Mark Post said synthetic meat could reduce the environmental footprint of meat by up to 60%. "We would gain a tremendous amount in terms of resources," he said. Professor Post's group at Maastricht University in the Netherlands has grown small pieces of muscle about 2cm long, 1cm wide and about a mm thick. They are off-white and resemble strips of calamari in appearance. These strips will ...
