Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections are caused primarily by a single strain—USA300—of an evolving bacterium that has spread with “extraordinary transmissibility” throughout the United States during the past five years, according to a new study led by National Institutes of Health (NIH) scientists. CA-MRSA, an emerging public health concern, typically causes readily treatable soft-tissue infections such as boils, but also can lead to life-threatening conditions that are difficult to treat.
Same-sex couples are just as committed in their romantic relationships as heterosexual couples, say researchers who have studied the quality of adult relationships and healthy development. Their finding disputes the stereotype that couples in same-sex relationships are not as committed as their heterosexual counterparts and are therefore not as psychologically healthy.
A new study has found that cigarette smoking and alcohol consumption do not have an effect on ovarian cancer risk, while caffeine intake may lower the risk, particularly in women not using hormones. The study is published in the March 1, 2008 issue of CANCER, a peer-reviewed journal of the American Cancer Society.
A new study reveals significant racial and ethnic differences in the treatment and survival of patients with soft-tissue sarcomas, a rare but dangerous cancer that begins in muscle, fat, blood vessels or other supporting tissue of the body.

The existing research and development and business model of the pharmaceutical industry is failing pregnant women, according a policy paper published this week in PLoS Medicine.
A parasitic infection common in China and Southeast Asia could be effectively reduced by controlling snail populations, according to research published in PLoS Medicine.
Denizens of oceans, lakes and even wet soil, diatoms are unicellular algae that encase themselves in intricately patterned, glass-like shells. Curiously, these tiny phytoplankton could be harboring the next big breakthrough in computer chips.
The environmental damage caused by rich nations disproportionately impacts poor nations and costs them more than their combined foreign debt, according to a first-ever global accounting of the dollar costs of countries' ecological footprints.
The Ebola virus first emerged in 1976 with outbreaks in Sudan and Zaire. There are several strains of the virus, which causes hemorrhagic fever and during outbreaks kills anywhere from 50-90 percent of its human victims.
Due to its virulent nature, and because no vaccines or treatments are available, scientists studying the agent have had to work under the most stringent biocontainment protocols, limiting research to a few highly specialized labs and hampering the ability of scientists to develop countermeasures.
Dividing the lips into zones based on structure may help cosmetic surgeons perform enhancement procedures with high patient satisfaction and few adverse effects, according to a report in the January issue of Archives of Facial Plastic Surgery, one of the JAMA/Archives journals.
