Fungus foot baths could save bees

One of the biggest world wide threats to honey bees, the varroa mite, could soon be about to meet its nemesis. Researchers at the University of Warwick are examining naturally occurring fungi that kill the varroa mite. They are also exploring a range of ways to deliver the killer fungus throughout the hives from bee fungal foot baths to powder sprays.

University of Minnesota researchers map out America's deadliest roads

Would you be surprised to learn that nine people died last year on the highway you take to work everyday? Or would you be shocked to see that six teenagers died within five miles of your home in fatal car accidents? With the help of the interactive maps on www.saferoadmaps.org developed by University of Minnesota researchers - you can learn those facts and more by simply typing in your address.

Colonial heritage metaphors used in US military conflicts

Boston, MA – July 24, 2008 – The historical reference to "Indian Country" presents a complex metaphor. For many Native Americans it signifies home, family, and territory; however, for others the term can refer to colonialism and Native American land under siege. Through the years the term has evolved to apply to contemporary events and has taken on additional and often contradictory meanings. In the latest issue of American Anthropologist, Stephen W. Silliman explores the reinterpretation of "Indian Country" in the 21st-century U.S.

Confidence a key to recent economic initiatives, U. of I. expert says

CHAMPAIGN, Ill. — Restoring confidence in the sputtering U.S. economy is at the heart of recent moves to shore up the nation's lagging financial and housing markets, a University of Illinois economist says.

Anne Villamil says propping up faith in an economy teetering on the brink of recession is as important as more tangible initiatives such as financial lifelines for cash-strapped mortgage lending giants Fannie Mae and Freddie Mac.

Penn researchers demonstrate a flexible, 1-step assembly of nanoscale structures

PHILADELPHIA –- Scientists at the University of Pennsylvania have created a one-step, repeatable method for the production of functional nanoscale patterns or motifs with adjustable features, size and shape using a single master "plate."

Limits on futures trading could boost gas prices, expert says

CHAMPAIGN, Ill. — Proposals to reign in wallet-draining gasoline prices by curbing speculation in oil markets would likely increase costs at the pump instead of trimming them, a University of Illinois economist says.

Scott Irwin argues congressional efforts to curb trading by speculators is a "misguided witch hunt" that ignores the root of America's energy problem – a finite global oil supply that has been stretched thin by surging demand in China, India and other developing countries.

Women's access to credit affects efficiency in rural households

Seattle, WA – July 24, 2008 – Rural strategies designed to induce economic growth often emphasize the need to improve access to capital for poor households. However, this approach implicitly assumes that family members pool all their resources and allocate them to their most efficient use. Men and women may differ in their access to credit and may choose not to alleviate their partners' constraints.

Wealth does not dictate concern for the environment

Stillwater, OK – July 24, 2008 – It has been a long-held assumption that poor nations will not support efforts to protect the environment since their citizens are too preoccupied with meeting basic needs, such as food and housing. However, a new study in The Sociological Quarterly reveals that citizens of poorer nations are just as concerned about environmental quality as their counterparts in rich nations.

Accretion discs show their true colors

Quasars are the brilliant cores of remote galaxies, at the hearts of which lie supermassive black holes that can generate enough power to outshine the Sun a trillion times. These mighty power sources are fuelled by interstellar gas, thought to be sucked into the hole from a surrounding 'accretion disc'. A paper in this week's issue of the journal Nature, partly based on observations collected with ESO's Very Large Telescope, verifies a long-standing prediction about the intensely luminous radiation emitted by these accretion discs.

You're more likely to do sport if you are white, middle class, and middle-aged

The comfortably off, white, and middle aged are the most likely to participate in sporting activities, reveals a 10 year study published ahead of print in the British Journal of Sports Medicine.

Furthermore, the gap between rich and poor, and black and white, appears to have widened, rather than narrowed in a decade, as overall participation in sports has actually increased, the research suggests.

The findings are based on data from several of the annual Health Surveys for England between 1997 and 2006. These draw on a nationally representative sample of households.

Cool! Nanoparticle research points to energy savings

Adding just the right dash of nanoparticles to standard mixes of lubricants and refrigerants could yield the equivalent of an energy-saving chill pill for factories, hospitals, ships, and others with large cooling systems, suggest the latest results from National Institute of Standards and Technology (NIST) research that is pursuing promising formulations.

Licking your wounds: Scientists isolate compound in human saliva that speeds wound healing

A report by scientists from The Netherlands published online in The FASEB Journal (http://www.fasebj.org) identifies a compound in human saliva that greatly speeds wound healing. This research may offer hope to people suffering from chronic wounds related to diabetes and other disorders, as well as traumatic injuries and burns. In addition, because the compounds can be mass produced, they have the potential to become as common as antibiotic creams and rubbing alcohol.

Why eating less can help the environment

An estimated 19 percent of total energy used in the USA is taken up in the production and supply of food. Currently, this mostly comes from non-renewable energy sources which are in short supply. It is therefore of paramount importance that ways of reducing this significant fuel consumption in the US food system are found.

Commercial bees spreading disease to wild pollinating bees

Bees provide crucial pollination service to numerous crops and up to a third of the human diet comes from plants pollinated by insects. However, pollinating bees are suffering widespread declines in North America and scientists warn that this could have serious implications for agriculture and food supply. While the cause of these declines has largely been a mystery, new research reveals an alarming spread of disease from commercial bees to wild pollinators.

Security flaws in online banking sites found to be widespread

ANN ARBOR, Mich.---More than 75 percent of the bank Web sites surveyed in a University of Michigan study had at least one design flaw that could make customers vulnerable to cyber thieves after their money or even their identity.

Atul Prakash, a professor in the Department of Electrical Engineering and Computer Science and doctoral students Laura Falk and Kevin Borders examined the Web sites of 214 financial institutions in 2006. They will present the findings for the first time at the Symposium on Usable Privacy and Security meeting at Carnegie Mellon University July 25.
