Nature research paper: Left–right symmetry of zebrafish embryos requires somite surface tension
Raw zoomed in image of a representative region of an embryo imaged using Viventis microscope. Scale bar, 25 μm. Image in overlaid with segmented notochord and somite boundaries . Segment length is determined with respect to the notochord. Yellow arrow represents local angle of the notochord. Scale bar, 25 μm. , Quiver plots of the eigen vectors upon application of Frangi vesselness filter. Orientation of the vectors represent directions of least change in fluorescent intensity.
, Lines that are less than 15 pixels apart are joined together by straight lines following which lines that do not represent notochord or somite boundaries are discarded. , Any remaining gaps in boundary detection are then connected by straight lines. Further details on statistics and reproducibility can be found in the Methods section. Initial AP lengths, lengths at 1 hr and lengths at 2 hr of somites one to eight are shown across the six multiview datasets.

Engineered jumpers overcome biological limits via work multiplication - NatureA comparison of the energetics of jumping between biological and engineered systems shows that engineered systems can greatly increase energy limits using the process of work multiplication, and this analysis leads to the demonstration of a 30-centimetre device jumping over 30 metres.
