Substituting soy nuts for other protein sources in a healthy diet appears to lower blood pressure in postmenopausal women, and also may reduce cholesterol levels in women with high blood pressure.

The American Heart Association estimates that high blood pressure (hypertension) affects approximately 50 million Americans and 1 billion individuals worldwide. The most common-and deadly-result is coronary heart disease, according to background information in the article. Women with high blood pressure have four times the risk of heart disease as women with normal blood pressure.

People whose blood shows signs of inflammation are more likely to later develop Alzheimer's disease than people with no signs of inflammation, according to a new study.

The study, which is part of the larger Framingham Heart Study, involved 691 healthy people with an average age of 79. Blood tests determined whether the participants had signs of inflammation. Then the participants were followed for an average of seven years. During that time, 44 of the participants developed Alzheimer's disease.

Communication ability among children who are intellectually disabled or have communication limitations (such as autism, down syndrome, or cerebral palsy) may soon be improved thanks to a research group of the University of Granada.

No matter where we are on the political spectrum, we all have the same underlying goals and behaviors: The pursuit of happiness, the American dream etc. This is, at the very least, the way psychologists had viewed political ideology for quite some time. However, new research may have identified the characteristics that lead us to lean ideologically to the left or right and it may be genetic.

For the first time anywhere, a researcher at the Hebrew University of Jerusalem has succeeded in observing in vivo the generation of neurons in the brain of a mammal.

Early-stage research has found that a new gene therapy can nearly eliminate arthritis pain, and significantly reduce long-term damage to the affected joints, according to a study published today in the journal Arthritis and Rheumatism.

While the study was done in mice, they are the first genetically engineered to develop osteoarthritis like humans, with the same genetic predisposition that makes some more likely to develop the disease, the authors said. If all goes well with a follow-up study currently underway, researchers will apply to the U.S. Food and Drug Administration for permission to begin human trials next year.

Certain army ants in the rainforests of Central and South America conduct spectacular predatory raids containing up to 200,000 foraging ants. Remarkably, some ants use their bodies to plug potholes in the trail leading back to the nest, making a flatter surface so that prey can be delivered to the developing young at maximum speed.

Last week it was reported that the ratings board of the motion picture industry is now going to factor in cigarette smoking as part of the overall rating of a film.Films with excessive smoking will now certainly get a PG-13, if not an R rating.The goal is to cut down on the influence on teen smoking behavior.There is clear correlation between the glamorization of cigarette smoking on screen and people smoking.

Rains are back, and we hardly remember how dry it was a couple of weeks ago. Usually, we do not associate moist tropical forests with drought, but during the ‘verano' it gets astonishingly dry in most Panamanian lowland forests, just as in many tropical forests worldwide: Plants suffer from drought, they grow slower, wilt and even die.

Physicists at the National Institute of Standards and Technology (NIST) have demonstrated a novel way of making atoms interfere with each other, recreating a famous experiment originally done with light while also making the atoms do things that light just won't do.

Their experiments showcase some of the extraordinary behavior taken for granted in the quantum world—atoms acting like waves and appearing in two places at once, for starters—and demonstrate a new technique that could be useful in quantum computing with neutral atoms and further studies of atomic hijinks.

Atoms interfering with themselves.
