Zika’s surface in stunning detail; mosquito tactics
We haven’t curbed the Zika epidemic yet. But cryo-electron microscopy — a newer, faster alternative to X-ray crystallography — at least reveals the structure of the virus, which has been linked to microcephaly (though not yet definitively). The anatomy of the virus’s projections gives clues to how the virus is able to attach to and infect cells, and could provide toeholds for developing antiviral treatments and vaccines. Read coverage in the Washington Post and see the full paper in Science.
Meanwhile, as The New York Times reports, scientists are coming together in an effort to control Zika by genetically manipulating the mosquito that spreads it, Aedes aegypti. …
