Urban legend warns shoveling snow causes heart attacks, and the legend seems all too accurate, especially for male wintery excavators with a family history of premature cardiovascular disease. However, until recently this warning was based on anecdotal reports.

Two of the most important cardiology associations in the US include snow -shoveling on their websites as a high risk physical activity, but all the citation references indicate that this warning was based one or two incidents.

Being impulsive can lead us to say things we regret, buy things we really don't need, engage in behaviors that are risky and even develop troublesome addictions. But are different kinds of hastiness and rashness embedded in our DNA?

A new study suggests the answer is yes - especially if you're a man.

The research, led by University of Nebraska-Lincoln assistant professor of psychology Scott Stoltenberg, found links between impulsivity and a rarely researched gene called NRXN3. The gene plays an important role in brain development and in how neurons function.

The newly discovered connection, which was more prevalent among men than women in the study, may help explain certain inclinations toward alcohol or drug dependence, Stoltenberg said.

After men become fathers for the first time, they show significant decreases in crime, tobacco and alcohol use, according to a new, 19-year study.

Researchers assessed more than 200 at-risk boys annually from the age of 12 to 31, and examined how men's crime, tobacco, alcohol, and marijuana use changed over time. While previous studies showed that marriage can change a man's negative behavior, they had not isolated the additional effects of fatherhood.

When obese men take a relatively small dose of resveratrol in purified form every day for a month, their metabolisms change for the better. In fact, the effects appear to be as good for us as severe calorie restriction. Resveratrol is a natural compound best known as an ingredient in red wine.

"We saw a lot of small effects, but consistently pointing in a good direction of improved metabolic health," said Patrick Schrauwen of Maastricht University in The Netherlands.

The findings in the November issue of the Cell Press journal Cell Metabolism are the first to report the clinical effects of resveratrol.

Bisexual men have unique health needs compared to exclusively homosexual and heterosexual men, but the stigma they face makes learning of their needs -- and even reaching these men in their "hidden communities" -- difficult for public health professionals, say Indiana University researchers.

University of British Columbia researchers have identified three major patterns that emerge among couples dealing with male depression. These can be described as "trading places," "business as usual" and "edgy tensions."

Published in the Social Science & Medicine journal and led by UBC researcher John Oliffe, the paper details how heterosexual couples' gender roles undergo radical shifts and strain when the male partner is depressed and the female partner seeks to help. Depression, a disorder often thought of as a women's health issue, is underreported in men, and little is known about how heterosexual couples respond when the male partner is depressed.

The "Lance Armstrong effect" could become a powerful new weapon to fight cancer cells that develop resistance to chemotherapy, radiation and other treatments, scientists say in a report in the ACS journal Molecular Pharmaceutics.

It is known that the unmarried are in general more likely to die than their married counterparts and there is some indication that the divide is in fact getting worse.

New research published in BioMed Central's open access journal BMC Public Health looks at the changes in cancer survival over the past 40 years and show that the difference in mortality between the married and never married, especially between married and never married men, has also increased.

While there's no crying in baseball, as Tom Hanks' character famously proclaimed in "A League of Their Own," crying in college football might not be a bad thing, at least in the eyes of one's teammates.

Although college football players feel pressure to conform to some male stereotypes, players who display physical affection toward their teammates are happier, according to new research. The findings were reported in a special section of Psychology of Men & Masculinity, published by the American Psychological Association.

A new study published in the British Journal of Sports Medicine* highlights the injury risks for schoolboys playing rugby.

The research shows that the chance of a school player suffering an injury during a single season is at least 12 per cent and, according to some research, could be as high as 90 per cent.

The researchers from Queen Mary, University of London and Cass Business School, City University say there is an urgent need to inform children, parents and coaches alike about the level of risk involved and that more should be done to reduce the risk.
