Stainier* (Current Biology 20, 1840–1845; October 26, 2010) In the text and in Figure 3A of this article, we refer to chromosome 12/LG12. This is incorrect; chromosome 12 in the text and LG12 in Figure 3A should ref...

Myriapod-like ambulation of a segmented microrobot

Segmented myriapod-like bodies may offer performance benefits over more common fixed body morphologies for ambulation. Here, the design of a segmented ambulatory microrobot with a flexible backbone is presented. A dynamic model describing the motion of the microrobot is used to determine body parameters. A three-segment microrobot was fabricated using the Smart Composite Microstructures process...

Social carnivores outperform asocial carnivores on an innovative problem

The presumed oldest flying insect: more likely a myriapod?

The early fossil record of insects is scarce, with only few finds in the Devonian. All these finds appear problematic and controversial, partly due to incomplete preservation and challenging interpretation of many structures. We provide details of one of these important forms, Rhyniognatha hirsti from the famous Rhynie Chert Lagerstätte with up-to-date 3D imaging techniques. The fossil has been...

Carnivores in Northern Latitudes

The first mammals were probably nocturnal (McNab 1978; Kemp 1982) and many extant orders of small mammals have retained this trait. This behaviour is presumably due to the measure of protection from predation that darkness provides (Crawford 1934; Falls 1968; Daan and Aschoff 1982). Large, herbivorous mammals are less restricted to the nocturnal phase (e.g. Bunnell and Harestad 1990) and have b...
