A 'private bandwidth' for communication in bats: Evidence from insular horseshoe bats
...phidae). These bats find their way in the dark and detect
insect prey by emitting long ultrasound calls mainly made of a constant frequency. Different rhinolophid species show different frequency values. It has been proposed that such differences are large enough to allow recognition of conspecifics. The...

Study finds gender differences in renal and other genes contributing to blood pressure
...oach provides over 90 percent statistical power to detect
genes contributing as little as three percent to blood pressure variation. The research team also scored over 60,000 genotypes at 35 gene locations involved in two major pathways regulating blood pressure, kidney or adrenergic or regulation. The gen...

the spores, scientists do not know where to look for them. In addition, blindly testing environmental samples has thus far failed to yield evidence of the spores. Infected frogs can be treated with fungicides to remove the pathogen, but researchers...
A sensory organ, not the brain, differentiates male and female behavior in some mammals
