International research project: The more available alcohol is, the more likely that people will drink heavily

The bulk of knowledge about alcohol consumption and problems comes from high-income countries. The International Alcohol Control (IAC) study was established to collect and compare data from both high- and middle/low-income countries. New IAC results show that heavy-drinking New Zealanders tend to buy cheaper, off-premise alcohol, and purchase it at later times. The International Alcohol Control (IAC) study is a newly developed international collaborative project designed to collect comparative data on alcohol consumption and policy-relevant behaviors in both high- ...

Binge drinking is harmful to older drinkers, may be hidden by weekly average

Studies examining the potential health benefits of moderate drinking generally focus on average levels of drinking rather than drinking patterns. A new study shows that, among older moderate drinkers, those who binge drink have a significantly greater mortality risk than regular moderate drinkers. Numerous studies have highlighted the purported association between moderate drinking and reduced mortality. However, these analyses have focused overwhelmingly on average consumption, a measure that masks diverse, underlying drinking patterns such as weekend heavy episodic ...

Affordable Care Act brings crucial health coverage to jail population

WASHINGTON, DC (March 3, 2014)—Under the Affordable Care Act, an estimated 4 million people who have spent time in jail will have better access to health coverage for conditions that might—if left untreated—result in higher health care costs and an increased risk of recidivism. That's the conclusion of an analysis by researchers at the George Washington University School of Public Health and Health Services (SPHHS). "Health reform gives people with a history of jail time access to continuous health care for the first time ever," says lead author Marsha Regenstein, PhD, ...

Experts call for prison health improvements

PROVIDENCE, R.I. [Brown University] — The very premise of prison invites members of society to think of the people there as walled-off and removed. But more than 95 percent of prisoners will return to the community, often carrying significant health burdens and associated costs with them. In an article in the March issue of the journal Health Affairs, several experts who participated in a scientific workshop convened by the National Research Council and the Institute of Medicine recommend several steps and ideas consistent with health reform to improve care for prisoners ...

Postcode lottery for race relations

People's racial prejudices are influenced by where they live, reports a new study led by Oxford University psychologists. The researchers found that levels of racial prejudice among white people drop significantly when they live in ethnically mixed communities, even when they do not have direct contact with minorities. Simply seeing white strangers interacting positively with ethnic minorities is enough to reduce racial prejudice. The researchers have called this positive effect 'passive tolerance', likening it to the negative effect of 'passive smoking' where a smoky ...

Increasing homogeneity of world food supplies warns of serious implications for farming and nutrition

CALI, COLOMBIA (3 MARCH 2014)—A comprehensive new study of global food supplies confirms and thoroughly documents for the first time what experts have long suspected: over the last five decades, human diets around the world have grown ever more similar—by a global average of 36 percent—and the trend shows no signs of slowing, with major consequences for human nutrition and global food security. "More people are consuming more calories, protein and fat, and they rely increasingly on a short list of major food crops, like wheat, maize and soybean, along with meat and dairy ...

The surface of the sea is a sink for nitrogen oxides at night

The surface of the sea takes up nitrogen oxides that build up in polluted air at night, new measurements on the coast of southern California have shown. The ocean removes about 15 percent of these chemicals overnight along the coast, a team of atmospheric chemists reports in the early online edition of the Proceedings of the National Academy of Sciences the week of March 3. Nitrogen oxides, formed by the burning of fossil fuels, generate photochemical smog. Atmospheric chemists would like to account for the fates of these molecules in a kind of budget that indentifies ...

Amazon's canopy chemistry is a patchwork quilt

Washington, D.C.— In many ways, plants act as chemical factories, using energy from sunlight to produce carbon-based energy and taking nutrients from the soil in order to synthesize a wide variety of products. Carnegie scientists asked the question: How much does the portfolio of chemicals generated by plants vary, depending on the surrounding environment, and what can this tell us about how we interact with forests? The answer involved climbing into the Amazonian canopy, resulting in the discovery that the forest's chemical portfolios form a rich mosaic that varies with ...

We want to save water, but do we know how?

BLOOMINGTON, Ind. -- Many Americans are confused about the best ways to conserve water and have a slippery grasp on how much water different activities use, according to a national online survey conducted by an Indiana University researcher. Experts say the best strategy for conserving water is to focus on efficiency improvements such as replacing toilets and retrofitting washing machines. However, the largest group of the participants, nearly 43 percent, cited taking shorter showers, which does save water but may not be the most effective action. Very few participants ...

Researchers identify 'carbohydrates in a coal mine' for cancer detection

Researchers at New York University and the University of Texas at Austin have discovered that carbohydrates serve as identifiers for cancer cells. Their findings, which appear in the journal Proceedings of the National Academy of Sciences, show how these molecules may serve as signals for cancer and explain what's going on inside these cells, pointing to new ways in which sugars function as a looking glass into the workings of their underlying structures. "Carbohydrates can tell us a lot about what's going on inside of a cell, so they are potentially good markers for ...

New discovery solves problem of anti-inflammatory substance

There have been great expectations regarding the production of a drug to block the enzyme LTA4 hydrolase, which plays a key role in the body's inflammatory response. However, in clinical trials, such molecules have proven to be only moderately effective. Now, researchers at Karolinska Institutet have successfully refined their understanding of why previous substances have been less effective – and in so doing have produced a molecule that gets around the problem. Consequently, there is once again hope of a new anti-inflammatory drug based on the principal of blocking LTA4 ...

Gut microbes spur development of bowel cancer

It is not only genetics that predispose to bowel cancer; microbes living in the gut help drive the development of intestinal tumors, according to new research in mice published in the March issue of The Journal of Experimental Medicine. Bowel cancer, also called colorectal cancer, results from a series of genetic changes (mutations) that cause healthy cells to become progressively cancerous, first forming early tumors called polyps that can eventually become malignant. Although mutations can occur anywhere in the human intestine, certain types of colorectal cancer tend ...

In academia, men more likely to cooperate with lower-ranked colleagues

In academic circles at least, women tend to cooperate with same-sex individuals of higher or lower rank less often than men do. So say researchers who report evidence on March 3 in the Cell Press journal Current Biology. The findings are based on a study of the publication records of professors working at 50 North American universities. "People are often upset to hear evidence of sex differences in behavior," says Joyce Benenson of Harvard University. "But the more we know, the more easily we can promote a fair society." The findings might seem somewhat counterintuitive. ...

People with sleep apnea may be at higher risk of pneumonia

People with sleep apnea appear to be at higher risk of pneumonia than people without, according to a study published in CMAJ (Canadian Medical Association Journal). Sleep apnea is characterized by disrupted sleep, caused when the upper airway becomes obstructed by soft tissue, cutting off oxygen. It has been linked to several types of heart disease and cognitive impairment. People with obstructive sleep apnea are at higher risk of aspiration while sleeping. To determine whether sleep apnea is linked to the development of pneumonia, Taiwanese researchers followed 34 ...

Calculating cooperation

It's long been a popular stereotype: Men are hugely competitive, meaning cooperative effort is the exception rather than the norm, while women have a tendency to nurture relationships with others, making them much more likely to cooperate with one another. A new Harvard study, however, is turning that cliché on its head. In fact, within academic departments women of different social or professional "ranks" cooperate with each other less well than men do, according to Joyce Benenson, an Associate of Harvard's Human Evolutionary Biology Department and Professor of Psychology ...
