New research strengthens the link between water pollution and rising male fertility problems. The study shows for the first time how a group of testosterone-blocking chemicals is finding its way into UK rivers, affecting wildlife and potentially humans.

Scientists in Oregon and India are reporting an advance toward developing the first saliva test to diagnose and monitor effectiveness of treatment for Type 2 diabetes. The number of cases of that disease (18 million in the United States alone) has doubled during the last 30 years in parallel with the epidemic of obesity.

Phenotypic noise is a novel concept in biology that explains the division of labor among pathogens. Researchers have now developed a new method that simplifies the process by which the genes carrying the pathogenic properties are found.

Researchers have unraveled crucial details of how aging causes broken bones to heal slowly, or not at all, according to an article in the Journal of Bone and Mineral Research. The research team also successfully conducted preclinical tests on a potential new class of treatments designed to “rescue” healing capability lost to aging.
First came the earthquakes, then the torrential rains. But the relentless march of sand across once fertile fields and bays, a process set in motion by the quakes and flooding, is probably what did in America’s earliest civilization.

Blast overpressure is generated from the firing of weapons and may cause brain injury. The brain may be injured by the noise, which is produced when, for example, an anti-tank weapon (Bazooka, Karl Gustav) or a howitzer (Haubits) is fired. Scientists have demonstrated mild injury to brain tissue.
Using a NASA radar flying aboard India’s Chandrayaan-1 spacecraft, scientists are getting their first look inside the moon’s coldest, darkest craters.

Scientists who study how human chemistry can permanently turn off genes have typically focused on small islands of DNA believed to contain most of the chemical alterations involved in those switches. But after an epic tour of so-called DNA methylation sites across the human genome in normal and cancer cells, scientists have found that the [...]
European researchers are re-examining the causes of road accidents and studying which technologies can make our roads safer for everyone.
