Use of retail medical clinics located in pharmacies and other retail settings increased 10-fold between 2007 and 2009, according to a new RAND Corporation study.

The determining factors in choosing a retail medical clinic over a physician's office were found to be age, health status, income and proximity to the clinic. No link between availability of a primary care physician and retail clinic use was found.

The study was published in the American Journal of Managed Care.

Although women have little or no control over some of the risk factors for breast cancer, such as those related to aging and genetics, they may be able to reduce their chances for developing the disease by avoiding certain environmental risks. BREAST CANCER AND THE ENVIRONMENT: A LIFE COURSE APPROACH, a new report from the Institute of Medicine, assesses the breast cancer risk posed by various environmental factors, identifies actions that offer potential to reduce women's risk for the disease, and recommends targets for future research. The report, sponsored by Susan G.

COLUMBIA, Mo. – While most people only gain about a pound of weight during the holiday season, that pound may never come off, increasing the likelihood of becoming overweight or obese and the risk of related health problems, according to a National Institutes of Health study. University of Missouri dietitians recommend families maintain healthy diet and exercise habits during the holiday season beginning with Thanksgiving.

WEST LAFAYETTE, Ind. - Purdue University researchers have discovered a fine-tuning mechanism involved in plant root growth that has them questioning whether a popular herbicide may have unintended consequences, causing some plants to need more water or nutrients.

Angus Murphy, a professor of horticulture, and Wendy Peer, an assistant professor of horticulture, study the movement of auxin, a plant hormone essential for plant development. They showed that ABCB4, a protein responsible for moving auxin into cells, also removes the hormone when too much has accumulated.

In a new study published this month in the Journal of the American Chemical Society, researchers with The University of Texas Health Science Center at San Antonio have pinpointed the cancer-fighting potential in the bat plant, or Tacca chantrieri.

Susan Mooberry, Ph.D., leader of the Experimental Development Therapeutics Program at the Cancer Therapy & Research Center and a professor of pharmacology at the UT Health Science Center, has been working to isolate substances in the plant, looking for a plant-derived cancer drug with the potential of Taxol.

Montreal -- Too much fast food, poor meal choices and bad eating habits are causing more Canadians to be overweight or obese. Despite this trend, individuals who eat well are 20 per cent less likely to be obese, according to a study by Concordia University economists published in the Journal of Primary Care & Community Health.

Research published in the European Journal of Epidemiology by Costanzo S, Di Castelnuovo de Gaetano G et al has sought to separate the effects of wine, beer or spirit drinking in relation to fatal and non-fatal cardiovascular events. The Italian authors carried out an updated meta-analysis on the relationship between wine, beer or spirit consumption and cardiovascular outcomes, using state-of-the-art statistical techniques.

Global food demand could double by 2050, according to a new projection reported this week in the journal Proceedings of the National Academy of Sciences (PNAS).

The analysis also shows that the world faces major environmental challenges unless agricultural practices change.

Scientists David Tilman and Jason Hill of the University of Minnesota (UMN) and colleagues found that producing the amount of food needed could significantly increase levels of carbon dioxide and nitrogen in the environment, and may cause the extinction of numerous species.

Chapel Hill, NC – Researchers from UNC Lineberger Comprehensive Cancer Center are part of a team that has identified a protein, called P-Rex1, that is key to the movement of cells called melanoblasts. When these cells experience uncontrolled growth, melanoma develops.

Melanoma is one of the only forms of cancer that is still on the rise and is one of the most common forms of cancer in young adults. The incidence of melanoma in women under age 30 has increased more than 50 percent since 1980. Metastases are the major cause of death from melanoma.

Researchers at King's College London have discovered how one of the most common household painkillers works, which could pave the way for less harmful pain relief medications to be developed in the future.

Paracetamol, often known in the US and Asia as acetaminophen, is a widely-used analgesic (painkiller) and the main ingredient in everyday medications such as cold and flu remedies. Although discovered in the 1890s and marketed as a painkiller since the 1950s, exactly how it relieves pain was unknown.

Amsterdam -- "Would legal regulation and control of drugs better protect children?" is a question posed by former President of Brazil, Fernando Henrique Cardoso in an editorial to be published in the January issue of Elsevier's International Journal of Drug Policy (IJDP).

The editorial, "Children and drug law reform" follows the March 2011 report of the Global Commission on Drug Policy, chaired by Cardoso, which made a series of recommendations for reforms of drug laws, including experiments with legal regulation and control.

Ecological tourism has no effect on the presence of large mammals in the Amazon, according to a study that for the first time compares the biological diversity of ecotourism zones with that of protected areas. Furthermore, it can help to protect the biodiversity of areas that are not officially protected yet are vital in the ecological framework.

CAMBRIDGE, Mass. – The U.S. government could save the economy hundreds of billions of dollars per year by 2050 by spending a few billion dollars more a year to spur innovations in energy technology, according to a new report by researchers at the Harvard Kennedy School.

Achieving major cuts in carbon emissions in the process will also require policies that put a substantial price on carbon or set clean energy standards, the researchers find.

A health supplement used by bodybuilders could be the key to treating a life-threatening muscular dystrophy affecting hundreds of Australian children, new research shows.

The amino acid L-tyrosine had a "rapid and dramatic impact" on Nemaline Myopathy (NM) in laboratory tests on mice, significantly improving symptoms of the muscle-wasting disease, medical researchers from the University of New South Wales (UNSW) found.

Athens, Ga. – University of Georgia researchers have discovered that two proteins come together in an unexpected way to make a carbohydrate, a chain of sugar molecules, in plant cell walls. This fundamental discovery changes the way scientists think about how plant cell walls are made and opens a new door to converting plants to biofuels and other carbon-based products.
