Are we more -- or less -- moral than we think?

If asked whether we'd steal, most of us would say no. Would we try to save a drowning person? That depends—perhaps on our fear of big waves. Much research has explored the ways we make moral decisions. But in the clinch, when the opportunity arises to do good or bad, how well do our predictions match up with the actions we actually take?

A nano-solution to global water problem: Nanomembranes could filter bacteria

BUFFALO, N.Y. -- New nanomaterials research from the University at Buffalo could lead to new solutions for an age-old public health problem: how to separate bacteria from drinking water.

To the naked eye, both water molecules and germs are invisible -- objects so tiny they are measured by the nanometer, a unit of length about 100,000 times thinner than the width of a human hair.

But at the microscopic level, the two actually differ greatly in size. A single water molecule is less than a nanometer wide, while some of the most diminutive bacteria are a couple hundred.

Transitioning to organic farming

MADISON, WI FEBRUARY 22, 2011 – As the organic food trend continues to grow; more farmers are converting from conventional agriculture to organic production. One of the fastest growing markets in the U.S. is the production of organic milk. The growth of this industry has prompted many farmers to transition their land to organic feed grain production. With transition on the rise, it is necessary for these farmers to have effective and economical organic management practices.

T. rex more hyena than lion

The ferocious Tyrannosaurus rex has been depicted as the top dog of the Cretaceous, ruthlessly stalking herds of duck-billed dinosaurs and claiming the role of apex predator, much as the lion reigns supreme in the African veld.

But a new census of all dinosaur skeletons unearthed over a large area of eastern Montana shows that Tyrannosaurus was too numerous to have subsisted solely on the dinosaurs it tracked and killed with its scythe-like teeth.

Patients with COPD have higher risk of shingles

Patients with chronic obstructive pulmonary disease (COPD) are at greater risk of shingles compared with the general population, according to a study published in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj101137.pdf. The risk is greatest for patients taking oral steroids to treat COPD.

Shingles, or herpes zoster, is a reactivation of the chicken pox virus resulting in a painful rash with lesions.

E-health must align with health care reform

To speed implementation of an electronic health record system in Canada, e-health policy must be closely aligned with the major strategic direction of health care reform and must take a bottom-up approach to engage people from clinicians to administrators, states a study published in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj100856.pdf.

Bisphenol A exposures lower in Canadians compared to Americans

Health Canada's declaration that bisphenol A is a health hazard makes it unique in the world but it must now follow through with legislation to protect people from exposure, states an analysis published in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj101408.pdf.

Captain Scott's century-old collections suggests marine life is capturing more carbon

Tiny Antarctic marine creatures collected 100 years ago by Antarctic explorer Captain Robert Falcon Scott give new clues about polar environmental change. By comparing present-day bryozoans – a sea-bed filter-feeding animal that looks like branching twigs – with specimens from Scott's expeditions scientists have found the first conclusive evidence of increased carbon uptake and storage by Antarctic marine life.

Financial security of Chinese American households depends on education, MU researcher finds

COLUMBIA, Mo. -- As the financial crisis continues, researchers have been focusing more attention on how individuals handle finances at home. Rui Yao, personal financial planning professor in the University of Missouri School of Human Environmental Sciences, surveyed the financial health of Chinese American households to gain a better understanding of how this particular group of people manages their personal finances.

Anti-clotting agent does not improve outcomes of patients with severe pneumonia

Use of the blood clot-inhibiting medication tifacogin does not appear to improve outcomes of patients with severe community-acquired pneumonia (sCAP), according to a study conducted by researchers from North and South America, Europe, Asia and Africa. The drug had shown some potential benefit in the sCAP subgroup of an earlier trial involving sepsis patients.

The findings were published online ahead of the print edition of the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.

Study: For a better workday, smile like you mean it

EAST LANSING, Mich. — Want to keep your boss happy? Smile at your customers. Want to keep yourself happy and productive? Smile like you mean it.

A new study led by a Michigan State University business scholar suggests customer-service workers who fake smile throughout the day worsen their mood and withdraw from work, affecting productivity. But workers who smile as a result of cultivating positive thoughts – such as a tropical vacation or a child's recital – improve their mood and withdraw less.

Don't blame 'the pill' for estrogen in drinking water?

WASHINGTON, Feb. 22, 2011 — The latest ACS podcast Global Challenges/Chemistry Solutions says it is a misconception that the estrogen hormones detected in drinking water supplies is related to birth control pills.

Smallest magnetic field sensor in the world

Further development of modern information technology requires computer capacities of increased efficiency at reasonable costs. In the past, integration density of the relevant electronic components was increased constantly. In continuation of this strategy, future components will have to reach the size of individual molecules. Researchers from the KIT Center for Functional Nanostructures (CFN) and IPCMS have now come closer to reaching this target.

Nanotechnology may lead to new treatment of liver cancer

Nanotechnology may open a new door on the treatment of liver cancer, according to a team of Penn State College of Medicine researchers. They used molecular-sized bubbles filled with chemotherapy drugs to prevent cell growth and initiate cell death in test tubes and mice.

Researchers evaluated the use of molecular-sized bubbles filled with C6-ceramide, called cerasomes, as an anti-cancer agent. Ceramide is a lipid molecule naturally present in the cell's plasma membrane and controls cell functions, including cell aging, or senescence.

Texas leafcutter ants aided, but also limited, by cold-tolerant fungus crops, research shows

AUSTIN, Texas—Texas leafcutter ants farm crops of fungus that evolved cold tolerance to Texas winters, just as northern farmers cultivate cold weather crops, researchers from The University of Texas at Austin show in a new paper published in the journal PNAS Early Edition.

Though the cold tolerant fungus gives the ants the ability to maintain winter gardens, the fungus is still sensitive enough to cold it limits the ant's ability to spread farther northward.
