PHILADELPHIA — Higher levels of total cholesterol and triglycerides, two types of fat, in the blood of men who underwent surgery for prostate cancer, were associated with increased risk for disease recurrence, according to a study published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.

Adoption of a combination of five key healthy behaviors is associated with a reduction in the risk of developing bowel cancer. Researchers from the German Institute of Human Nutrition Potsdam-Rehbruecke quantified the impact of combined multiple healthy lifestyle behaviors on the risk of developing bowel cancer, and found that this impact is stronger in men than in women.

The sanitation intervention delivered under the terms of the Government of India's Total Sanitation Campaign—the world's largest sanitation initiative—provided almost 25 000 individuals in rural India with access to a latrine. However, it did not reduce exposure to faecal pathogens or decrease the occurrence of diarrhoea, parasitic worm infections, or child malnutrition.

Three new species of leafhoppers from China in the genus Futasujinus were recently identified during a review of leafhoppers in museum collections in China, the UK, and Illinois. One of them, Futasujinus dietrichi, was "named after Dr. Chris Dietrich, University of Illinois, USA, in recognition of his good work on leafhoppers." The new species are described in an article in Annals of the Entomological Society of America.

Tempe, Ariz. (Oct. 9, 2014) - New Ebola research demonstrates that quick and forceful implementation of control interventions are necessary to control outbreaks and avoid far worse scenarios.

Researchers analyzed up-to-date epidemiological data of Ebola cases in Nigeria as of Oct. 1, 2014, in order to estimate the case fatality rate, proportion of health care workers infected, transmission progression and impact of control interventions on the size of the epidemic.

A Greek and international team of divers and archaeologists has retrieved stunning new finds from an ancient Greek ship that sank more than 2,000 years ago off the remote island of Antikythera. The rescued antiquities include tableware, ship components, and a giant bronze spear that would have belonged to a life-sized warrior statue.

(SALT LAKE CITY)—A University of Utah-led study using X-rays and neutron beams has revealed the inner workings of a master switch that regulates basic cellular functions, but that also, when mutated, contributes to cancer, cardiovascular disease and other deadly disorders.

In rare cases, patients with allergies to metals develop persistent skin rashes after metal devices are implanted near the skin. New research suggests these patients may be at increased risk of an unusual and aggressive form of skin cancer.

Metal alloys help make orthopedic implants stronger and more durable. But people with sensitivity to these metals, which include nickel, cobalt and chromium, can develop chronic inflammation that promotes the development of skin cancers, report researchers at Washington University School of Medicine and Barnes-Jewish Hospital in St. Louis.

"This is just the critical first step in a series of additional clinical trials that will have to be carried out to fully evaluate the promising vaccine," said Professor Samba Sow, Director General of CVD-Mali. "However, if it is eventually shown to work and if this information can be generated fast enough, it could become a public health tool to bring the current, and future, Ebola virus disease epidemics under control."

Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University have unveiled a new method to form tiny 3D metal nanoparticles in prescribed shapes and dimensions using DNA, Nature's building block, as a construction mold.

The ability to mold inorganic nanoparticles out of materials such as gold and silver in precisely designed 3D shapes is a significant breakthrough that has the potential to advance laser technology, microscopy, solar cells, electronics, environmental testing, disease detection and more.

MADISON, Wis. – In Wisconsin, bioenergy is for the birds. Really.

In a study published today in the journal PLOS ONE, University of Wisconsin-Madison and Wisconsin Department of Natural Resources (DNR) scientists examined whether corn and perennial grassland fields in southern Wisconsin could provide both biomass for bioenergy production and bountiful bird habitat.

SAN FRANCISCO -- The information that interprets the genetic code in a new embryo differs depending on whether it comes from the father or mother, researchers at San Francisco State University have found.

Most women are infected with HIV through vaginal intercourse, and without effective vaccines or microbicides, women who cannot negotiate condom use by their partners remain vulnerable. How exactly the virus establishes infection in the female reproductive tract (FRT) remains poorly understood. A study published on October 9th in PLOS Pathogens reports surprising results from a study of HIV transmission in the FRT of rhesus macaques.

CANCER RESEARCH UK scientists have discovered that lung cancers can lie dormant for over 20 years before suddenly turning into an aggressive form of the disease, according to a study published in Science* today (Thursday).

The team studied lung cancers from seven patients – including smokers, ex-smokers and never smokers. They found that after the first genetic mistakes that cause the cancer, it can exist undetected for many years until new, additional, faults trigger rapid growth of the disease.
