Optical Illusion Garments Can Create Desired Effect if Chosen Correctly

Mizzou study uses digital avatars to virtually assess fit, desired appearance

COLUMBIA, Mo. – Optical illusion garments have been popular for as long as people have tried to use clothing to enhance appearances, from A-line dresses that accentuate the waist to striped trousers that visually elongate an individual’s stride. However, knowing what outfit is right for one’s body can be challenging. New research from the University of Missouri reveals the future of fashion could lie in the use of digital avatars, which allow individuals to virtually try on clothing, revealing how effectively clothing might mask perceived flaws and draw attention to certain body parts.

A new way to get electricity from magnetism

‘Inverse spin Hall effect’ works in several organic semiconductors

By showing that a phenomenon dubbed the “inverse spin Hall effect” works in several organic semiconductors – including carbon-60 buckyballs – University of Utah physicists changed magnetic “spin current” into electric current. The efficiency of this new power conversion method isn’t yet known, but it might find use in future electronic devices including batteries, solar cells and computers. (more…)

Effects of Climate Change on West Nile Virus

A study projects how climate change may affect virus-carrying mosquitoes across the southern U.S. Changes are expected to vary with region, and the southern states should see a trend toward longer seasons of mosquito activity and smaller midsummer mosquito populations

The varied influence of climate change on temperature and precipitation may have an equally wide-ranging effect on the spread of West Nile virus, suggesting that public health efforts to control the virus will need to take a local rather than global perspective, according to a study published this week in the scientific journal Proceedings of the National Academy of Sciences.

Cutting Specific Atmospheric Pollutants Would Slow Sea Level Rise

Decreasing emissions of black carbon, methane and other pollutants makes a difference

With coastal areas bracing for rising sea levels, new research indicates that cutting emissions of certain pollutants can greatly slow sea level rise this century.

Scientists found that reductions in four pollutants that cycle comparatively quickly through the atmosphere could temporarily forestall the rate of sea level rise by roughly 25 to 50 percent.

The researchers focused on emissions of four heat-trapping pollutants: methane, tropospheric ozone, hydrofluorocarbons and black carbon. (more…)

Breast Cancer DNA Mutator Found

Masonic Cancer Center researchers discover a virus-fighting enzyme

It’s well known that sunlight and chemical carcinogens can mutate DNA, and that mutations are essential for cancer to develop.

One big mystery was what causes the thousands of mutations evident in most breast cancers.

Now researcher Reuben Harris, Masonic Cancer Center, University of Minnesota, and his colleagues have found evidence that one of our own proteins is a major source of these mutations. The researchers have just published evidence implicating the protein—an enzyme called APOBEC3B—in the international journal Nature. (more…)

UCLA Professor Leads Effort to Protect Africa’s Rainforests from Ravages of Climate Change

UCLA professor Thomas B. Smith will head an international research project investigating the effects of climate change on biodiversity in Central Africa’s rainforests, under a $4.95 million grant from the National Science Foundation.

UCLA will receive $3 million through the NSF’s Partnerships for International Research and Education (PIRE) program, the agency announced this week. Smith, the director of UCLA’s Center for Tropical Research and a professor with joint appointments at the Institute of the Environment and Sustainability and the department of ecology and evolutionary biology, will lead the team of U.S. and international researchers.

Study Finds Severe Climate Jeopardizing Amazon Forest

PASADENA, Calif. – An area of the Amazon rainforest twice the size of California continues to suffer from the effects of a megadrought that began in 2005, finds a new NASA-led study. These results, together with observed recurrences of droughts every few years and associated damage to the forests in southern and western Amazonia in the past decade, suggest these rainforests may be showing the first signs of potential large-scale degradation due to climate change.

An international research team led by Sassan Saatchi of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., analyzed more than a decade of satellite microwave radar data collected between 2000 and 2009 over Amazonia. The observations included measurements of rainfall from NASA’s Tropical Rainfall Measuring Mission and measurements of the moisture content and structure of the forest canopy (top layer) from the Seawinds scatterometer on NASA’s QuikScat spacecraft.

Violent Video Games Intensify anti-Arab Stereotypes

ANN ARBOR — Playing violent video games about terrorism strengthens negative stereotypes about Arabs, even when Arabs are not portrayed in the games.

That is one of the findings of an innovative new study in the January issue of Psychology of Violence, a peer-reviewed journal published by the American Psychological Association. (more…)
