This Week in PNAS

In the early, online edition of the Proceedings of the National Academy of Sciences, an international team describes apparent ties between gene flow restriction and pyrethroid insecticide resistance in Anopheles funestus, a mosquito that can carry malaria-causing parasites. Using microarrays and PCR-based microsatellite marker genotyping, the researchers assessed genome-wide transcription profiles and genetic diversity in An.
