The majority of advertising exposure occurs when the audience’s attention is focused elsewhere, such as while flipping through a magazine or browsing a web site. However, a new study reveals that even this incidental exposure to advertising may have a positive effect on consumer attitudes. Forthcoming in the June issue of the Journal of Consumer Research, the study revises existing theories of exposure advertising, specifically repeated views of web-based banner ads.

Nutritionists have long endorsed fish as part of a heart-healthy diet, and now some studies suggest that omega-3 fatty acids found in the oil of certain fish may also benefit the brain by lowering the risk of Alzheimer’s disease. In order to test whether an omega-3 fatty acid can impact the progression of Alzheimer’s disease, researchers supported by the National Institute on Aging (NIA), part of the National Institutes of Health, will evaluate one in a clinical trial, the gold standard for medical research.

Scientists have discovered how ocean circulation is working in the current that flows around Antarctica by tracing the path of helium from underwater volcanoes. The details are published in Nature this week.

The causes of "broken heart syndrome" remain a mystery, but doctors will soon have an easier time recognizing and treating this rare, life-threatening condition, thanks to data being reported at the 30th Annual Scientific Sessions of the Society for Cardiovascular Angiography and Interventions (SCAI), May 9–12, 2007, in Orlando, FL.

Researchers from Brown University in Providence, RI, have developed the largest registry of patients in the United States with Takotsubo cardiomyopathy, informally known as broken heart syndrome because it is often preceded by an emotional or physical shock of some kind and almost always strikes women. One thing is certain: Patients are usually critically ill during the first 48 hours.
