   High rates of evolution preceded shifts to sex-biased gene expression in Leucadendron, the most sexually dimorphic angiosperms

   Mathias Scharmann et al.

   In the dioecious plant genus Leucadendron, shifts to sex-biased gene expression occurred predominantly in genes with ancestrally high rates of expression evolution, and were not correlated with morphology.

   A small, computationally flexible network produces the phenotypic diversity of song recognition in crickets

   Jan Clemens et al.

   A computational model of the neuronal network that recognizes mating signals reveals network properties that support and constrain behavioral diversity in a species group.

   Ovipositor and mouthparts in a fossil insect support a novel ecological role for early orthopterans in 300 million years old forests

   Lu Chen et al.

   Hundreds of fossil remains shed new light on the evolution of grasshoppers, gryllids, and katydids and their ecological role 300 million years ago.

   Dinosaur bonebed amber from an original swamp forest soil

   Sergio Álvarez-Parra et al.

   The most prolific and oldest locality in which a rich dinosaur bonebed and fossiliferous amber have been found in association is revealed, allowing the reconstruction of an ancient terrestrial ecosystem with a detail and accuracy reached only exceptionally in palaeontology.

   Wings and halteres act as coupled dual oscillators in flies

   Tanvi Deora et al.

   Flight system of flies is driven by wings and mechanosensory halteres that operate as independently driven but coupled oscillators, thereby imparting robustness against wing or thorax damage.

   New fossils of Australopithecus sediba reveal a nearly complete lower back

   Scott A Williams et al.

   Newly recovered lumbar vertebrae belonging to Malapa Hominin 2, an adult female of the fossil hominin species Australopithecus sediba, demonstrate that this individual was adapted to upright posture and bipedal locomotion but also had adaptations for climbing in trees.

   Biomarkers in a socially exchanged fluid reflect colony maturity, behavior, and distributed metabolism

   Sanja M Hakala et al.

   Socially exchanged fluids passed mouth-to-mouth in ant colonies contain protein signatures of colony maturity and individual behavioral role, indicating that this fluid may underlie a distributed metabolism that functions over the scale of the colony.

    Unconventional conservation reveals structure-function relationships in the synaptonemal complex

    Lisa E Kursel et al.

    The protein components of an essential and conserved meiotic interface, the synaptonemal complex, have highly conserved coil-coiled domains and protein length, despite highly diverged sequence.
