MARSABIT, KENYA (21 October 2011) – In the midst of a drought-induced food crisis affecting millions in the Horn of Africa, an innovative insurance program for poor livestock keepers is making its first payouts today, providing compensation for some 650 insured herders in northern Kenya's vast Marsabit District who have lost up to a third of their animals.

Vancouver − Health prevention strategies to help Canadians achieve their optimal health potential could add a decade or more of healthy years to the average lifespan and save the economy billions of dollars as a result of reduced cardiovascular disease, says noted cardiologist Dr. Clyde Yancy.

Post-menopausal women with high levels of hormones such as estrogen or testosterone are known to have a higher risk of breast cancer. New research published in BioMed Central's open access journal Breast Cancer Research looked at eight different sex and growth hormones and found that the risk of breast cancer increased with the number of elevated hormones - each additional elevated hormone level increased risk by 16%.

The condition tuberous sclerosis, due to mutation in one of two tumor suppressor genes, TSC1 or TSC2, causes the growth of non-malignant tumors throughout the body and skin. These tumors can be unsightly and cause serious damage to organs. Growth of tumors in the brain may cause seizures and in the kidney, liver or heart, tumors can disrupt normal function, to the extent of causing the organ to fail.

There is no link between long-term use of mobile phones and tumours of the brain or central nervous system, finds new research published on bmj.com today.

In what is described as the largest study on the subject to date, Danish researchers found no evidence that the risk of brain tumours was raised among 358,403 mobile phone subscribers over an 18-year period.

Reasoning used in many highly cited cancer publications to support the relevance of animal and test tube experiments to human cancer is questionable, according to a study by researchers from Université Libre de Bruxelles published in the open-access journal PLoS Computational Biology on October 20th 2011.

A team of international researchers has discovered a new Ebola-like virus – Lloviu virus -- in bats from northern Spain. Lloviu virus is the first known filovirus native to Europe, they report in a study published in the journal PLOS Pathogens on Octobr 20th.

DNA ANALYSIS: A new and astonishing chapter has been added to North American prehistory in regards to the first hunters and their hunt for the now extinct giant mammoth-like creatures – the mastodons. Professor Eske Willerslev's team from the Centre for GeoGenetics, University of Copenhagen, has in collaboration with Michael Waters' team at the Center for the Study of the First Americans, University of Texas A&M, shown that the hunt for large mammals occurred at least 1,000 years before previously assumed.

Using one of the largest DNA data sets for a group of birds and employing next-generation sequencing methods, Smithsonian scientists and collaborators have determined the evolutionary family tree for one of the most strikingly diverse and endangered bird families in the world, the Hawaiian honeycreepers.

Not only have the researchers determined the types of finches that the honeycreeper family originally evolved from, but they have also linked the timing of that rapid evolution to the formation of the four main Hawaiian Islands.

Frequent spitting up, irritability and unexplained crying in infants are often very distressing to parents. Physicians frequently prescribe acid-suppressing drugs for these symptoms. However, gastroesophageal reflux disease (GERD) is an uncommon cause of these symptoms in otherwise thriving infants, and in his commentary published in the Journal of Pediatrics, Dr. Eric Hassall cautions against over-diagnosis of GERD and over-prescription of acid-suppressing drugs in children under one year of age.

Culture is not a trait that is unique to humans. By studying orangutan populations, a team of researchers headed by anthropologist Michael Krützen from the University of Zurich has demonstrated that great apes also have the ability to learn socially and pass them down through a great many generations.

Researchers at NYU Langone Medical Center today announce findings published in the October 20 issue of Nature that show for the first time the inhibition of both microRNA-33a and microRNA-33b (miR-33a/b) with chemically modified anti-miR oligonucleotides markedly suppress triglyceride levels and cause a sustained increase in high density lipoprotein cholesterol (HDL-C) "good" cholesterol.

CORVALLIS, Ore. – A new study concludes that men who experience persistently moderate or high levels of stressful life events over a number of years have a 50 percent higher mortality rate.

In general, the researchers found only a few protective factors against these higher levels of stress – people who self-reported that they had good health tended to live longer and married men also fared better. Moderate drinkers also lived longer than non-drinkers.

New Rochelle, NY, October 20, 2011—Spas that offer massage therapy using fragrant essential oils, called aromatherapy, may have elevated levels of potentially harmful indoor air pollutants such as volatile organic compounds (VOCs) and ultrafine particles, according to an article in Environmental Engineering Science, a peer-reviewed journal published by Mary Ann Liebert, Inc..
