Researchers at UT Southwestern Medical Center are reporting in the September issue of the American Heart Journal that women with a family history of heart disease are less likely than men to change habits such as smoking and infrequent physical activity.

They also are more likely to engage in lifestyle choices that increase their risk of heart disease than are women who did not report a history of heart disease.

“A family history of heart disease is as important an indicator of future cardiovascular health in women as it is in men – perhaps more important,” said Dr. Amit Khera, assistant professor of internal medicine and senior author of the study.

A new study says that salt-saturated brine moving through floating sea ice follows “universal transport properties” and that this new understanding can help anticipate the effects of global warming on the polar oceans and the microbial communities existing there.

According to this new model, similar porous materials – including ice on other worlds, such as Jupiter’s icy ocean-covered moon Europa – should follow the same rules.

“It means that almost the exact same formulas describing how water flows through sedimentary rocks in the Earth's crust apply to brine flow in sea ice, even though the microstructural details of the rocks are quite different from sea ice,” says University of Utah math Professor Ken Golden.

The AIDS Healthcare Foundation (AHF) today called on Gilead Sciences and Merck to immediately register and distribute the three-in-one, once daily lifesaving HIV treatment, Atripla, in developing countries.

When Atripla first received approval from the Food and Drug Administration (FDA) in July of 2006, advocates like AHF applauded the production of a single, once-a-day drug as a landmark step in treating HIV. However, since its approval, little progress has been made in expanding the availability of the treatment in the developing world, where only 28% of those in need of treatment were able to access it as of December 2006.

"This treatment is a standard therapy in the United States.

Breasts move far more than ordinary bras are designed to cope with and they also bounce more during exercise – up to 21 cm rather than the maximum 16 cm bounce measured in past studies, according to new research.

Ordinary bras can stop the bouncing but the new study by University of Portsmouth scientist Dr Joanna Scurr shows that breasts also move side-to-side and in and out and estimates are that more than 50 percent of women experience breast pain when exercising, regardless of cup size.

Dr Scurr’s study also found that breasts move as much during slow jogging as they do at maximum sprint speed.

An important finding has been made by McMaster researchers about Fragile X Syndrome (FXS), a sex-linked genetic disorder that affects approximately one in 4,000 males and one in 6,000 females.

FXS is the most common genetic disorder associated with mental impairment. The affected gene (FMR1) leads to inactivation of the FMR1 gene product, known as the fragile X mental retardation protein (FMRP).

Brain development in the absence of this protein leads to cognitive effects, learning and memory problems, attention deficit, hyperactivity and autistic behaviors. Many children go undiagnosed with Fragile X.

Melbourne, Florida -- Symetrics Industries, LLC announced today an award from the U.S. Army for approximately 300 Improved Data Modems (IDM) for installation on Army aircraft.
