The researchers found twice as many positive and negative ions in heavily wooded areas compared to open grassy areas. Plants have long been known as the lungs of the Earth, but a new finding has found they may also play a role in electrifying the atmosphere. Scientists have long suspected an association between trees and electricity but researchers from Queensland University of Technology (QUT) think they may have finally discovered the link. Dr Rohan Jayaratne and Dr Xuan Ling from QUT's International Laboratory for Air Quality and Health (ILAQH), led by Professor Lidia Morawska, ran experiments in six locations around Brisbane, including the Brisbane Forest Park, Daisy Hill and ...
Highly Flexible Despite Hard-Wiring: Even Slight Stimuli Change the Information Flow in the Brain

ScienceDaily (Mar. 23, 2012) — One cup or two faces? What we believe we see in one of the most famous optical illusions changes in a split second; and so does the path that the information takes in the brain. In a new theoretical study, scientists of the Max Planck Institute for Dynamics and Self-Organization, the Bernstein Center Göttingen and the German Primate Center now show how this is possible without changing the cellular links of the network. The direction of information flow changes, depending on the time pattern of communication between brain areas. This reorganisation can be triggered even by a slight stimulus, such as a scent or sound, at the right time. The way that ...

I've been tight-lipped for a while, but it's finally time to show you what the BBC calls a “Miracle Material.” Its actual name is graphene, given by the two scientists who won a Nobel Prize for their discovering it. And it's going to change the world...Graphene Sidebar “Graphene doesn't just have one application,” says Andre Geim, who made the find along with Konstantin Novoselov. "It is not even one material. It is a huge range of materials. A good comparison would be to how plastics are used." I'd say plastics is a conservative comparison. Let me show you what hundreds of researchers, companies, and governments are already doing ...

American solar panel manufactuers welcome Obama administration decision, saying it exposes unfair trade practices Chinese companies have acknowledged receiving cheap loans and other government support. Photograph: Ben Birchall/PA The Obama administration, which regularly champions America's clean energy industry, has delivered modest support for home-grown solar panel makers complaining of unfair competition from China In a much-anticipated decision, the commerce department on Tuesday said it would impose tariffs of 2.9% to 4.73% on Chinese-made solar panels, after finding the Beijing government was providing illegal subsidies to manufacturers. The commerce department could impose ...

Ancient sites spotted from space, say archaeologists Thousands of possible early human settlements have been discovered by archaeologists using computers to scour satellite images. Jason Ur said he had found about 9,000 potential new sites in north-eastern Syria. Computers scanned the images for soil discolouration and mounds caused when mud-brick settlements collapsed. Dr Ur said surveying the same area on the ground would have taken him a lifetime. Writing in the Proceedings of the National Academy of Sciences, the researcher told BBC News: "With these computer science techniques, however, we can immediately come up with an enormous map which is methodologically very ...
Geomagnetic data reveal unusual nature of recent solar minimum

Geomagnetic data reveal unusual nature of recent solar minimum March 19, 2012 Since the mid-1800s, scientists have been systematically measuring changes in the Earth's magnetic field and the occurrence of geomagnetic activity. Such long- term investigation has uncovered a number of cyclical changes, including a signal associated with 27-day solar rotation. This is most clearly seen during the declining phase and minimum of each 11-year solar cycle, when the Sun's magnetic dipole is sometimes tilted with respect to the Sun's rotational axis. With the Sun's rotation and the emission of solar wind along field lines from either end of the solar magnetic dipole, an outward ...
Modified bacteria make bio-diesel from carbs

A class of chemical compounds best known today for fragrance and flavor may one day provide the clean, green and renewable fuel with which truck and auto drivers fill their tanks. Researchers at the U.S. Department of Energy's Joint BioEnergy Institute (JBEI) have engineered Escherichia coli (E. coli) bacteria to generate significant quantities of methyl ketone compounds from glucose. In subsequent tests, these methyl ketones yielded high cetane numbers -- a diesel fuel rating comparable to the octane number for gasoline -- making them strong candidates for the production of advanced biofuels. "Our findings add to the list of naturally occurring chemical compounds that could serve ...
PayPal Showed The Future Of Retail Today -- And It's NOT The New Credit Card Reader

PayPal Showed The Future Of Retail Today -- And It's NOT The New Credit Card Reader The big news today from PayPal was a tiny credit-card reader called PayPal Here. It lets any small business owner with an iPhone or Android phone take credit card payments. But there was actually a far more interesting technology shown today. It lets you walk into a store and buy a product without touching your phone, money, or a credit card -- or even taking your wallet out. Like the credit card reader, it's pretty obviously inspired by Square, whose Card Case app was introduced about six months ago. But I never actually got how revolutionary the concept of touchless retail payment was until I ...

I wonder how the BBC environment correspondent Richard Black would report it if the Climatic Research Unit's Phil Jones were suddenly to confess that everything he'd said in the last two decades about the anthropogenic warming threat was total rubbish. I'm guessing something like: "Hero climate scientist announces glorious discovery: world saved, research at CRU now shows!" I wonder how the New York Times, or the Guardian environment pages or Huffington Post would report it if NASA's James Hansen were to burst in with a machine gun and grenades at the next Heartland climate sceptics' conference and wipe out half the delegates.

Long-distance space travel is the dream of many scientists and space-enthusiasts, but there's a catch - it could result in the travellers destroying the planet they land on. Long distance space travel could create the ultimate 'killer entrance', devastating your destination and anything around the arriving spacecraft, according to calculations by Professor Geraint Lewis and two honours students from the University of Sydney. The University of Sydney team is the first to publish on the effects of theoretical space travel using an Alcubierre warp drive, in the leading journal of the American Physical Society, Physical Review D. The Alcubierre warp drive is a theoretical tool ...
Evidence Builds That Meditation Strengthens the Brain

ScienceDaily (Mar. 14, 2012) — Earlier evidence out of UCLA suggested that meditating for years thickens the brain (in a good way) and strengthens the connections between brain cells. Now a further report by UCLA researchers suggests yet another benefit. Eileen Luders, an assistant professor at the UCLA Laboratory of Neuro Imaging, and colleagues, have found that long-term meditators have larger amounts of gyrification ("folding" of the cortex, which may allow the brain to process information faster) than people who do not meditate. Further, a direct correlation was found between the amount of gyrification and the number of meditation years, possibly providing further ...

In a top-secret location in Berkeley, Patrick Kennedy is showing a reporter around a tiny living space — so compact in fact that, at 160 sq ft, it is the smallest apartment one is legally allowed to build. “It is how small you can go without causing psychological problems,” jokes Kennedy, who, through his company, Panoramic Interests, is responsible for developing swathes of Berkeley. His projects include the Gaia Building on Allston Way, the Berkeleyan Apartments on Oxford Street, and the Touriel Building on University. The “bijou” apartment in which we are standing, with its trompe l’oeil view of the Bay Bridge, is the prototype for the SmartSpace, a ...

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

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 ...
Parkinson's Disease Stopped in Animal Model: Molecular 'Tweezers' Break Up Toxic Aggregations of Proteins

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 ...
