Ohio State University scientists combined bed bugs' own chemical signals with a common insect control agent to create a more effective extermination method. The researchers said they discovered stimulating the bed bugs by spraying their environment with synthetic versions of their alarm pheromones makes them more likely to walk through agents called desiccant dusts, which kill the bugs by making them highly susceptible to dehydration. Doctoral candidate Joshua Benoit, the study's lead author,...

Drug combination could lower risk of fracture by 30 to 50 percent in women, according to Saint Louis University research Taking a DHEA supplement combined with vitamin D and calcium can significantly improve spinal bone density in older women, according to a new study from a Saint Louis University scientist and his colleagues at Washington University. "The results of our study are very promising. Similar studies have demonstrated much smaller benefits for bone than we found. However, calcium...

New study looks at effect of oral contraceptive use in resistance exercise training Many active young women use oral contraceptives (OC) yet its effect on their body composition and exercise performance has not been thoroughly studied. A team of researchers has now examined the effects of OC on female muscle mass, and found that oral contraceptive use impairs muscle gains in young women, and is associated with lower hormone levels. The findings are contained in a new study entitled Oral...

Swedish scientists have discovered that a female moth can discern a male's ancestry, age and possibly reproductive fitness from the scent of his pheromones. The study by Jean-Marc Lassance and Christer Lofstedt of Lund University in Sweden focused on an analysis of the pheromones used by the European Corn Borer (Ostrinia nubilalis). The researchers studied the influence of pheromones on mating preferences and carried out an analysis of the composition of the scent and genetic makeup of the...

New lab evidence suggests a preventive effect of DHEA in prostate cancer.  DHEA is a steroid hormone produced by the body's adrenal glands. Some men take it as an over-the-counter supplement because it has been suggested DHEA can reverse aging. Researchers at the National Center for Complementary and Alternative Medicine (NCCAM) found a way to manipulate DHEA levels in cells in order to understand its effects. "Something is happening in the prostate tissue microenvironment that is...

Mountain pine beetles devastating lodgepole pine stands across the West might best be kept in check with aerial application of flakes containing a natural substance used in herbal teas that the insects release to avoid overcrowding host trees, according to a team of scientists.Findings from the U.S. Forest Service-funded study appear in the February issue of Forest Ecology and Management. The study was conducted in California and Idaho, and showed how applications of laminated flakes...

Scientists say a synthetic chemical sex smell could help rid North America's Great Lakes of a devastating pest known as the "vampire fish." A laboratory version of a male sea lamprey pheromone was deployed to trick ovulating females into swimming upstream into traps, US researchers said. The vampire fish, known formally as the sea lamprey, has become a harmful parasite to native species of the Great Lakes since its accidental introduction in the 1800s. Recreational fishing of the Great Lakes...

The ants, one of the most successful groups of insects, are of particular interest because they form advanced colonies, and can constitute up to 15 percent of the total animal biomass of a tropical rainforest. They belong to the order Hymenoptera and are close relatives of the vespoid wasps. Ants appear in amber, found in central New Jersey, believed to be from the Cretaceous period. It is thought that they evolved from the wasps that had appeared during the Jurassic period. They are...
