USC researchers have developed a mathematical model to forecast metastatic breast cancer survival rates using techniques usually reserved for weather prediction, financial forecasting and surfing the Web.

For decades, medical schools have taught doctors that the best way to treat cancer and metastatic progression is to memorize a list of tumors and their typical migration patterns. Metastasis is the development of malignant tumor growths elsewhere from the primary site of cancer.

Washington, DC--More research is needed to better understand polycystic ovary syndrome - one of the leading causes of infertility, according to the Scientific Statement issued by the Endocrine Society.

As many as 5 million women nationwide may have polycystic ovary syndrome (PCOS), according to the U.S. Department of Health and Human Services' Office on Women's Health.

Dead wood has decreased dramatically in the boreal zone due to intensive forest management. Several species dependent on dead wood have suffered from this decline. Beavers dam water systems, raising floods into surrounding shore forests. The flooding kills the trees due to oxygen deprivation.

Adding seaweed to processed foods such as frozen pizzas, hot dogs and dried pasta will reduce cardiovascular diseases, concludes a new scientific article. One suggestion is to replace 5% of the flour in pizza dough with dried and granulated seaweed.

According to the World Health Organization (WHO) cardiovascular diseases are the number one cause of premature death globally. Ironically, many of the pathologies leading to premature death from cardiovascular diseases are not only widespread, but they are preventable.

Superconductivity is a fascinating quantum phenomenon in which electrons form pairs and flow with zero resistance. However, strong enough magnetic field can break electron pairs and destroy superconductivity. Surprisingly, experimental groups led by Prof. Ye and Prof. Zeitler in Groningen and Nijmegen found that superconductivity in thin films of MoS2 could withstand an applied magnetic field as strong as 37 Tesla.

JUPITER, FL, November 23, 2015 - Scientists from the Florida campus of The Scripps Research Institute (TSRI) have shown for the first time how a previously unknown process works to promote infection in a number of dangerous viruses, including dengue, West Nile and Ebola.

The new study also points to a potential treatment, an experimental antibiotic that appears to inhibit infection by these deadly viruses, all of which lack vaccines and treatments.

Migration between different communities of bacteria is the key to the type of gene transfer that can lead to the spread of traits such as antibiotic resistance, according to researchers at Oxford University.

While horizontal gene transfer - also known as bacterial sex - has long been acknowledged as central to microbial evolution, why it is able to exert such a strong effect has remained a mystery.

Keeping tobacco products out of view in convenience stores significantly reduces teenagers' susceptibility to future cigarette use compared to when tobacco advertising and products are visible, according to a new RAND Corporation study.

The study, conducted in a one-of-a-kind laboratory replica of a convenience store, is the first to use a realistic setting to examine whether limiting displays of cigarettes and other tobacco products in retail outlets can reduce the intention of young people to begin smoking.

Champion of regeneration, the freshwater polyp Hydra is capable of reforming a complete individual from any fragment of its body. It is even able to remain alive when all its neurons have disappeared. Researcher the University of Geneva (UNIGE), Switzerland, have discovered how: cells of the epithelial type modify their genetic program by overexpressing a series of genes, among which some are involved in diverse nervous functions. Studying Hydra cellular plasticity may thus influence research in the context of neurodegenerative diseases.

A coalition formed by the New York City Department of Health and Mental Hygiene (DOHMH) which included a team from Mount Sinai to increase colorectal cancer screening rates in New York City resulted in a 40 percent increase in screening rates over four years. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the program may serve as a foundation for other communities to boost cancer screening rates.

A concerted effort to increase colorectal cancer screening rates led to a dramatic increase in NYC screening colonoscopy rates among average-risk men and women and eliminated racial/ethnic disparities in screening. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the program may serve as a foundation for other communities to boost cancer screening rates.

Engineers at the University of California, San Diego developed a new technology that uses an oscillating electric field to easily and quickly isolate drug-delivery nanoparticles from blood. The technology could serve as a general tool to separate and recover nanoparticles from other complex fluids for medical, environmental, and industrial applications.

Looking after people with late-stage Ebola at home puts people at greatest risk of catching it themselves - according to research from the University of East Anglia.

A new paper on risk factors for transmitting the deadly virus recommends better provision of health care facilities to ensure that people with the disease don't have to be cared for at home.

The study also finds that changing funeral traditions during outbreaks - particularly to allow cremation - could help stop the spread of future outbreaks.

A new Government-backed code which could slash UK carbon dioxide emissions by 220 million tonnes and protect rare wildlife by restoring moors, bogs and mires has been launched.

The Peatland Code is unveiled at the World Forum for Natural Capital in Edinburgh on the morning of 23 November following a successful two-year trial, which has seen businesses fund peatland restoration projects in southwest England, the Lake District and Wales.

An independent group of 19 experts from around the globe, convened by the Harvard Global Health Institute (HGHI) and the London School of Hygiene & Tropical Medicine, has issued a hard-hitting analysis of the global response to the 2014-15 Ebola outbreak in West Africa, published in The Lancet.
