Genetics

  • Around the World

    In science news around the world this week, France's latest attempt to keep genetically modified crops from its fields was rebuked by a scientific panel at the European Food Safety Authority; a Senate committee wants to sink the U.S. military's biofuels program; police prevented U.K. activists from destroying an experiment to test a strain of genetically modified wheat; and the European Commission said that open access "will be the norm" for studies funded through Europe's £80 billion Horizon 2020 research program.

  • Random Sample

    An analysis of the DNA sequence from three species of Heliconius butterflies and several subspecies reveals that those with the same color patterns have the same versions of key genes, holdovers from extensive hybridization within the genus. A recent master's degree thesis at European University Viadrina Frankfurt (Oder) in Germany is generating waves—though not the "time waves" the student was looking for. And this week's numbers quantify deaths of children under 5 caused by preventable infectious diseases, U.S. adults who sleepwalk, and pages in the Encyclopedia of Life.

  • Going Solid-State

    The first nanopore sequencers will depend on protein pores, but many in the field envision replacing these biological channels with solid-state ones.
