| Open AccessEvolutionary conservation of early mesoderm specification by mechanotransduction in Bilateria
Mechanical cues can induce morphogenetic processes during development. Here the authors show that mechanical changes during embryonic development in both zebrafish and Drosophilalead to nuclear localization of β-catenin, which regulates genes required for early mesoderm development in both species.

| Open AccessNovel survey method finds dramatic decline of wild cotton-top tamarin population
For conservation purposes, accurate methods are required to track cotton-top tamarins in their natural habitat. As existing census methods are not appropriate for surveying these monkeys, a lure-transect method combined with playback vocalization was used here to allow accurate counting of the animals.
