As Apple grows, so will the number of viruses that can affect it systems. Today, it issued a Java update to keep one of these viruses, the Flashback trojan, at bay. Flashback is a type of malware that is transferred to your computer by masquerading as a safe browser plug-in. When a person goes to an infected website housing the malware, he will be prompted to download a plugin, such as flash, in order to view content. Giving permission allows the malware to execute and download to your computer. Evolved versions of the virus use a hole in Apple’s version of Java to download to your Mac immediately after you open the webpage. Russian antivirus vendor Doctor Web estimates up to ...

Since 2006, something strange has been happening to North America's commercial beehives. Beekeepers are finding that many of the boxed hives ranged throughout their apiaries have been inexplicably abandoned by worker bees. These ghost-hives typically have ample stores of honey and pollen, and hold gestating colony broods, sometimes even a lone queen. This phenomenon is called Colony Collapse Disorder (CCD), and two papers published recently in the journal Science say that it is correlated with the presence of a ubiquitous class of insecticide called neonicotinoids. A newer study published in the Bulletin of Insectology suggests that this insecticide is introduced into bee colonies ...

To test their algorithm, the researchers designed and built a system of "smart pebbles"--cubes about 10 millimeters to an edge, with processors and magnets built in. [Photo: M. Scott Brauer via MIT News]MIT researchers from the Distributed Robotics Laboratory (DRL) are working on the very first steps towards nano-bot technology. In their “Smart Sand” project, the researches hope to make tiny, sand-grain-sized, self-contained computers that can duplicate any object. One day, the researchers imagine that you will be able to deposit an object into a box of sand-grain-sized computers and pull out a full-size replica of the original object a few seconds later.

“By allowing bacteria to stay alive after antibiotic treatment, we believe we can also prevent the emergence of antibiotic resistance..." New treatments that combat the growing problem of antibiotic resistance by disarming rather than killing bacteria may be on the horizon, according to a new study. Published in Nature Structure and Molecular Biology, research led by Monash University showed a protein complex called the Translocation and Assembly Module (TAM), formed a type of molecular pump in bacteria. The TAM allows bacteria to shuttle key disease-causing molecules from inside the bacterial cell where they are made, to the outside surface, priming the bacteria for ...

The discovery in Africa of a one million year old fireplace may enable us to identify when humans first began using fire Cooking is a universal in human culture. The mixing and heating of raw ingredients to make dinner is a fundamental part of our lives, one of the most noticeable things that separates us from even our closest animal cousins. The advantage of this method of preparing food is clear: it makes food tastier, easier to digest and makes the extraction of energy from raw ingredients quicker and more efficient. All useful things if you want to power an over-sized, energy-hungry brain without having to spend all your time foraging and chewing food. Richard Wrangham, a ...

Why skepticism is rising So, we’re told, liberals trust science more than conservatives do. The implication — freely peddled in much news coverage — is that conservatives are either dumber or more politicized than liberals. This fits in neatly with a narrative established in screeds like Chris Mooney’s 2005 book, “The Republican War Against Science.” The only problem is it’s not true. Consider an interesting new study by Gordon Gauchat, a postdoctoral fellow in sociology at the University of North Carolina-Chapel Hill. The folks at Inside Higher Ed summarized it this way: “Just over 34 percent of conservatives had confidence in science as an ...

"Flow." Although it can be annoyingly difficult to define with any precision and virtually impossible to measure objectively, everyone intuitively knows what it is, and most people have experienced some form of it at one time or another. It's that state of effortless concentration that leads to superior performance, either mental or physical. Everything superfluous to the task at hand is shut out of the mind. At the highest level, Michael Jordan sees a basketball hoop that's four feet wide and cannot be missed; Einstein is able to conjure the complete structure of the universe inside his head. Attempts to find the flow are not new. For most of human existence, it has had ...
Is this finally proof we're NOT causing global warming? The whole of the Earth heated up in medieval times without human CO2 emissions, says new study

Evidence was found in a rare mineral that records global temperatures Warming was global and NOT limited to Europe Throws doubt on orthodoxies around 'global warming' Current theories of the causes and impact of global warming have been thrown into question by a new study which shows that during medieval times the whole of the planet heated up. It then cooled down naturally and there was even a 'mini ice age'. A team of scientists led by geochemist Zunli Lu from Syracuse University in New York state, has found that contrary to the ‘consensus’, the ‘Medieval Warm Period’ approximately 500 to 1,000 years ago wasn’t just confined to Europe.

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 ...

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 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 ...
