Fly-inspired sound detector: New device based on a fly's freakishly acute hearing for futuristic hearing aids

The fly can pinpoint the location of a chirping cricket with remarkable accuracy because of its freakishly acute hearing, which relies upon a sophisticated sound processing mechanism that really sets it apart from all other known insects. Researchers have now developed a tiny prototype device that mimics the parasitic fly’s hearing mechanism, which may be useful for a new generation of hypersensitive hearing aids.

Butterflies could hold key to probes that repair genes

New discoveries about how butterflies feed could help engineers develop tiny probes that siphon liquid out of single cells for a wide range of medical tests and treatments, according to researchers. The technology could be used for medical devices, nanobioreactors that make complex materials and flying "micro-air vehicles" the size of an insect. View the Original article

Antarctic midge's genome is smallest in insects to date: Bare-bones genome is adaptation to deep freeze

Scientists who sequenced the genome of the Antarctic midge suspect the genome’s small size -- the smallest in insects described to date -- can probably be explained by the midge’s adaptation to its extreme living environment. View the Original article
