A 'private bandwidth' for communication in bats: Evidence from insular horseshoe bats
...tant 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 proved that in Sardinia, Mediterranean (Rhinolophus euryale) and lesser (R.. hipposideros) horseshoe bats show divergence...

kinds of key food-spoilage amines with 97 percent accuracy. Researchers also used the polymer to check the freshness of a tuna by detecting the amount of amines present in the sample. The sensitivity of the described assay is better than the typical ...

Clones on task serve greater good, evolutionary study shows
...h sun. It keeps you in the zone. The group studied different
cloned offspring of the Arabadopsis, a plant of the mustard family commonly used to test genetic questions. Arabadopsis can have many offspring that are genetically identical. Yet, just like human twins, these identical plants still have subtle indiv...

parts of the body. Blencowe attributes these new findings in part to the power of a new tool that he, together with his colleagues including Profs. Brendan Frey (Department of Electrical and Computer Engineering) and Timothy Hughes (Banting and Bes...
Interaction of just 2 genes governs coloration patterns in mice

types of mutations in two different
genes each contribute to the light coloration of beach mice," Hoekstra says. "This work represents a...
