Olive oil makes you feel full (3/22/2013)

Reduced-fat food products are gaining in popularity. But whether these products are effective or not is a matter of dispute: While it is true that they contain fewer calories, people tend to overcompensate by eating more. Now a study has shown how oils and fats regulate the sensation of feeling full after eating, with olive oil leading the way. So what makes this oil so effective? ...> Full Article

Aggressive advertising makes for aggressive men (3/13/2013)

Does advertising influence society, or is it merely a reflection of society's pre-existing norms? Where male attitudes are concerned, a new study implicates magazine advertisements specifically aimed at men as helping to reinforce a certain set of views on masculinity termed "hyper-masculinity." The article by Megan Vokey, a Ph.D. candidate from the University of Manitoba, and colleagues is published in Springer's journal Sex Roles. ...> Full Article

Study could explain why some people get zits and others don't (3/10/2013)

The bacteria that cause acne live on everyone's skin, yet one in five people is lucky enough to develop only an occasional pimple over a lifetime. What's their secret? Researchers have discovered that acne bacteria contain "bad" strains associated with pimples and "good" strains that may protect the skin. The findings could lead to a myriad of new therapies to prevent and treat the disfiguring skin disorder. ...> Full Article

A prospective study by U.K. researchers found that adolescents who are double-jointed -- medically termed joint hypermobility -- are at greater risk for developing musculoskeletal pain as they get older, particularly in the shoulders, knees, ankles and feet. Findings published in Arthritis & Rheumatism, a journal of the American College of Rheumatology, indicate that children with joint hypermobility are approximately twice as likely to develop pain at these joints. ...> Full Article

Good bacteria may expunge vancomycin-resistant bacteria from your gut (3/4/2013)

Too much antibiotic can decimate the normal intestinal microbiota, which may never recover its former diversity. That, in turn, renders the GI tract vulnerable to being colonized by pathogens. Now researchers show that reintroducing normal microbial diversity largely eliminated vancomycin-resistant enterococci from the intestinal tracts of mice. The investigators showed further that the findings may apply to humans. ...> Full Article


New injectable hydrogel encourages regeneration and improves functionality after a heart attack (3/4/2013)

New injectable hydrogel encourages regeneration and improves functionality after a heart attack University of California, San Diego bioengineers have demonstrated in a study in pigs that a new injectable hydrogel can repair damage from heart attacks, help the heart grow new tissue and blood vessels, and get the heart moving closer to how a healthy heart should. The results of the study were published Feb. 20 in Science Translational Medicine. ...> Full Article


Being stoic for the spouse's sake comes at a high cost (3/3/2013)

In the wealth of studies about parental grief, little attention has been paid to precisely how couples relate to each other as they struggle to come to terms with the death of a child. A new study published in Psychological Science, a journal of the Association for Psychological Science, addresses this gap in bereavement research by focusing on the way that couples together process the grief of losing a child. ...> Full Article

Aspirin and omega-3 fatty acids work together to fight inflammation (3/2/2013)

Aspirin and omega-3 fatty acids work together to fight inflammationExperts tout the health benefits of low-dose aspirin and omega-3 fatty acids but the detailed mechanisms involved in their effects are not fully known. Now researchers reporting in Chemistry & Biology show that aspirin helps trigger the production of molecules called resolvins that are naturally made by the body from omega-3 fatty acids. These resolvins shut off, or "resolve," the inflammation that underlies destructive conditions such as inflammatory lung disease, heart disease, and arthritis. ...> Full Article
