Whatever you collect – porcelain dolls, precious stones, shoes, thimbles, watches or fans – your hobby could easily become a psychological disorder that European researchers say affects more than 10 percent of the population. The researchers, from Granada University, say that as long as collectors exercise somecontrol, then “collecting items is good from a psychological […]
A group of pathogens including a fungus and family of viruses may be working together to cause the decline in honeybees known as colony collapse disorder, say researchers from the United States Department of Agriculture (USDA). “There might be a synergism between two very different pathogens,” explained USDA’s Jay Evans. “When they show up together […]
Honeybees in colonies affected by colony collapse disorder (CCD) have higher levels of pathogens than their non-affected counterparts, but no individual pathogen can be singled out as the cause of CCD, according to a new international study. The researchers, from Penn State’s College of Agricultural Sciences, the University of Liege, Gembloux Agricultural University, North Carolina […]
An analysis by Penn State researchers of beehive wax has shown unprecedented levels of fluvalinate and coumaphos – pesticides used in the hives to combat varroa mites – in all hive samples. The researchers also found lower levels of 70 other pesticides (used to protect agricultural crops) and metabolites of those pesticides in pollen and […]
A new imaging project from UCLA reveals that the brains of people with body dysmorphic disorder (BDD) look normal, but function abnormally when processing visual details. People who suffer from BDD perceive themselves as ugly and disfigured. Individuals with BDD often fixate on an imagined flaw in appearance or a slight physical abnormality. To fix […]
A new study in the Proceedings of the Royal Society B tries to uncover why several genes with strong associations to schizophrenia have evolved rapidly thanks to positive selection during human evolution. The international team of geneticists found a higher prevalence of positive selection on genes known to be associated with the disorder than a […]
The sudden disappearance of honeybees (colony collapse disorder) in many parts of the country might be related to pesticide exposure, says Washington State University entomologist Walter Sheppard. The pesticide is question has been used for the past ten years to combat parasitic mites that plague the bees. “To keep bees, especially on a commercial level, […]
A mysterious ailment called Colony Collapse Disorder (CCD) is causing agricultural honeybees around the country to abandon their hives and disappear. Now, University of Montana (UM) honeybee researchers have been enlisted to look into the phenomenon in the hope of uncovering what’s bugging the bees. “Individual beekeepers are really taking a beating,” UM entomologist Jerry […]
Research from the Neuropsychiatric Institute at UCLA demonstrates the potential of a substance found in yohimbe tree bark to assist in the recovery from anxiety disorders. In the latest in a series of studies of how mice acquire, express and extinguish conditioned fear, the UCLA team found yohimbine helps mice learn to overcome the fear […]
