A new study published in the International Journal of Andrology reveals that semen quality has significantly deteriorated during the last ten years in Finland, a country that previously was a region with high sperm counts. At the same time, the inci…
Hydrocephalus in Ugandan children and other developing countries is seasonal, linked to farm animals and in part, caused by previous bacterial infection, according to an international team of researchers from Uganda and the United States, who beli…
Horses are prone to develop genital cancer, especially as they grow older. Male horses are more commonly affected than mares but both sexes suffer from the condition, which is extremely difficult to treat and may result in the animals’ death. Beca…
A virus previously thought to be associated with chronic fatigue syndrome is not the cause of the disease, a detailed study has shown. The research shows that cell samples used in previous research were contaminated with the virus identified as XMRV…
Retinitis pigmentosa is an inherited eye disorder characterized by progressive loss of vision that in many instances leads to legal blindness at the end stage.
In a ChIP-Seq based approach, the researchers identified a key regulatory role of the t…

Babies are more vulnerable to serious head injury during a fall than had been previously thought, according to new research that may also begin to help child abuse investigators distinguish between accidental and intentional injury. Whitaker investigator Susan Margulies of the University of Pennsylvania found that rotational forces generated by a baby’s head hitting a hard surface can cause widespread, potentially serious brain injury. This can include internal bleeding, which can damage tissue and alter brain function, and nerve cell damage, which can impair thinking, sensation, and other mental functions.
Genetic differences that prevent tiny blood vessels from relaxing may be one reason why some people have high blood pressure, or hypertension, according to research led by scientists at Washington University School of Medicine in St. Louis. The findings are published in the February issue of the Journal of Clinical Investigation. “These findings provide new insights into the cause of hypertension and how normal blood pressure is regulated,” says lead investigator Kendall J. Blumer, Ph.D., professor of cell biology and physiology. “This may lead to a way of determining the underlying cause of a person’s hypertension and the most effective treatment for that individual.”
