Are we intellectually lazy? Yes we are, but we do know when we take the easy way out, according to a new study by Wim De Neys and colleagues, from the CNRS in France. Contrary to what psychologists believe, we are aware that we occasionally answer easier questions rather than the more complex ones we were asked, and we are also less confident about our answers when we do. The work is published online in Springer's journal Psychonomic Bulletin & Review.

New York University College of Nursing's Professor Michele Shedlin, PhD, recently published a paper, "Sending-Country Violence and Receiving-Country Discrimination: Effects on the Health of Colombian Refugees in Ecuador," on-line in the Journal of Immigrant and Minority Health, February 2, 2013.

As the name suggests, you can't digest resistant starch so it ends up in the bowel in pretty much the same form it entered your mouth. As unlovely as that seems, once in the bowel this resistant starch does some important things, including decreasing bowel pH and transit time, and increasing the production of short-chain fatty acids. These effects promote the growth of good bugs while keeping bad bugs at bay.

Stillbirth rates in First Nations and Inuit populations in Quebec are higher than in the general population, especially in late gestation and at term, found a new study in CMAJ (Canadian Medical Association Journal).

"Aboriginal populations in Canada [First Nations and Inuit] rank at the top of the list of disadvantaged groups with the highest rates of stillbirth in the Western world," writes Dr. Nathalie Auger, Institut national de santé publique du Québec, with coauthors. Rates are 2 times those of the non-Aboriginal population.

People with multiple illnesses are much more likely to be admitted to hospital unexpectedly, and mental health issues and economic hardship further increase the likelihood, according to a study in CMAJ (Canadian Medical Association Journal).

CAMBRIDGE, Mass. — In the search for renewable alternatives to gasoline, heavy alcohols such as isobutanol are promising candidates. Not only do they contain more energy than ethanol, but they are also more compatible with existing gasoline-based infrastructure. For isobutanol to become practical, however, scientists need a way to reliably produce huge quantities of it from renewable sources.

It is well known that horses show symptoms of stress when ridden but relatively little attention has been paid to the effects on their riders. This is surprising, as equestrian sports rely on the close cooperation between the animals and their riders. How does the horse-rider team cope with the stress involved in competing in an equestrian event?

ROCHESTER, Minn. -- Smokeless tobacco users who said they didn't want to quit changed their minds or significantly cut back when given nicotine lozenges or tobacco-free snuff in a Mayo Clinic study. The findings are published in the February issue of Addictive Behaviors.

Hundreds of tiny fungal particles found in the lungs of asthma sufferers could offer new clues in the development of new treatments, according to a team of Cardiff University scientists.

In the first large study of its type, published in the journal, BMC Infectious Diseases, a team of researchers from Cardiff University's School of Medicine have uncovered large numbers of fungi present in healthy lungs.

12 years revealed a clear trend: as coffee drinking increased, the risk of death decreased. Study author Neal Freedman, PhD, MPH, National Cancer Institute, discusses the significance of these findings and the potential links between coffee drinking, caffeine consumption, and various specific causes of disease in an interview in Journal of Caffeine Research.

ATLANTA- Pregnant women who received the H1N1 influenza vaccine during the 2009 pandemic were less likely to have premature babies, and their babies weighed more on average.

A single mutation in a moth gene has been shown to be able to produce an entirely new scent. This has been shown in a new study led by researchers from Lund University in Sweden. In the long run, the researchers say that the results could contribute to tailored production of pheromones for pest control.

The true cost of war is being masked by the secretive and largely unaccountable activities of a private security industry, according to a new study.

ANN ARBOR, Mich. — An antidepressant drug used since the 1960s may also hold promise for treating sickle cell disease, according to a surprising new finding made in mice and human red blood cells by a team from the University of Michigan Medical School.

The discovery that tranylcypromine, or TCP, can essentially reverse the effects of sickle cell disease was made by U-M scientists who have spent more than three decades studying the basic biology of the condition, with funding from the National Institutes of Health.

Misshapen cell nuclei are frequently observed in the cells of people with cancer and other diseases, but what causes the abnormality -- and why it is associated with certain disorders -- has remained unclear.
