In a new study published in the Quarterly Journal of Experimental Psychology, UCLA psychologists found that almost none of their subjects could draw the logo correctly from memory. Out of 85 UCLA undergraduate students, only one correctly reproduced the Apple logo when asked to draw it on a blank sheet of paper. Fewer than half the students correctly identified the actual logo when they were shown it among a number of similar logos with slightly altered features.

The official global target of a 2°C temperature rise is 'utterly inadequate' for protecting those at most risk from climate change, says a lead author on the Intergovernmental Panel on Climate Change (IPCC) in a Climate Change Responses editorial. The commentary is an inside-view of a two-day discussion at the Lima Conference of the Parties (COP) on the likely consequences of accepting an average global warming target of 2°C versus 1.5°C (measured from pre-industrial times until 2100).
Honey bees use different sets of genes, regulated by two distinct mechanisms, to fight off viruses, bacteria and gut parasites, according to researchers at Penn State and the Georgia Institute of Technology.
Antibiotic consumption in livestock worldwide could rise by 67 percent between 2010 and 2030, and possibly endanger the effectiveness of antimicrobials in humans, according to researchers from Princeton University, the International Livestock Research Institute, the Université Libre de Bruxelles and the Center for Disease Dynamics, Economics and Policy.
A new study has revealed that the thickness of Antarctica's floating ice shelves has recently decreased by as much as 18 percent in certain areas over nearly two decades, providing new insights on how the Antarctic ice sheet is responding to climate change.
Just as crocus and daffodil blossoms signal renewal and the start of a warmer season on land, a similar "greening" event--a massive phytoplankton bloom--unfolds each spring in the Atlantic Ocean from Bermuda to the Arctic. But, what happens to all that organic material produced in the surface ocean?
The fact that the neutron is slightly more massive than the proton is the reason why atomic nuclei have exactly those properties that make our world and ultimately our existence possible.
80 years after the discovery of the neutron, a team of physicists from France, Germany, and Hungary headed by Zoltán Fodor, a researcher from Wuppertal, has finally calculated the tiny neutron-proton mass difference. The findings confirm the theory of the strong interaction.
It may sound like the makings of a joke, but answering the question of how chickens crossed the sea may soon provide more than just a punch line.
Michigan State University researcher Eben Gering has collaborated with a team in a study of the mysterious ancestry of the feral chicken population that has overrun the Hawaiian Island of Kauai. Their results, published in the current issue of Molecular Ecology, may aid efforts to curtail the damage of invasive species in the future, and help improve the biosecurity of domestic chicken breeds.
Using high-performance computing and genetic engineering to boost the photosynthetic efficiency of plants offers the best hope of increasing crop yields and feed a planet expected to have 9.5 billion people on it by 2050, researchers report in the journal Cell.
Rhodiola rosea (R. rosea), or roseroot, may be a beneficial treatment option for major depressive disorder (MDD), according to results of a study in the journal Phytomedicine led by Jun J. Mao, MD, MSCE, associate professor of Family Medicine, Community Health and Epidemiology and colleagues at the Perelman School of Medicine of University of Pennsylvania.
Buildings destroyed by the 2011 Tohoku earthquake released thousands of tons of climate-warming and ozone-depleting chemicals into the atmosphere, according to a new study. New research suggests that the thousands of buildings destroyed and damaged during the 9.0 magnitude earthquake and tsunami that struck Japan four years ago released 6,600 metric tons (7,275 U.S. tons) of gases stored in insulation, appliances and other equipment into the atmosphere.
Nasal drops of harmless bacteria can inhibit a related bug that sometimes causes meningococcal disease, according to new findings published online in Clinical Infectious Diseases. The study--conducted among college students, a group at higher risk for this often serious illness--suggests a new approach that could help suppress outbreaks of the disease, if supported by future research.
The American Gastroenterological Association (AGA) has released new guidelines on the management of asymptomatic neoplastic pancreatic cysts found incidentally during computed tomography (CT) or magnetic resonance imaging (MRI).
The author of a commentary being published in Annals of Internal Medicine explains how the AGA's bold new recommendations will affect the way physicians consider diagnostic testing. The new guidelines back away from previous recommendations that were more aggressive.
Before a male damselfly hot-headedly enters into a duel of aerial sparring, it first works out its strategy. It gives its opponent's wings a once-over to assess its strength, knowing that more transparent wings and larger red spots generally show a stronger rival. Those who then decide to engage in long fights either try to wear their opponent down, or dazzle them with brilliant aerial moves that are too hard to follow. These damselfly war game strategies are set out in a study published in Springer's journal The Science of Nature - Naturwissenschaften.
Antibiotic resistance is poised to spread globally among bacteria frequently implicated in respiratory and urinary infections in hospital settings, according to new research at Washington University School of Medicine in St. Louis.
The study shows that two genes that confer resistance against a particularly strong class of antibiotics can be shared easily among a family of bacteria responsible for a significant portion of hospital-associated infections.
