A Doppler on wheels image of a tornadic thunderstorm near La Grange, Wyoming (USA) captured during the VORTEX2 project. In the velocity image on the left, Blues/green represent winds moving towards the radar, and reds/yellows indicate winds moving away from the radar. The reason that some of the darker blues contain red/yellow within them is a trait known as Aliasing, where the winds are moving faster than the radar can detect. In the reflectivity image on the right, the main body of the storm can be seen, with the appendage on the bottom of the storm being a hook echo, which is associated directly with the tornado, and the tornado circulation itself can be seen as the doughnut like shape in the later part of the animation.

Computer simulation of how the distribution of the growth hormone auxin changes over time across the growing tip of a plant. The absence of auxin in a cell is represented by black, while the highest concentration is shown in bright green. Cell boundaries are indicated in red, primordial cells marked with blue dots.

Vocalizations of a mudskipper during territorial display. Left panel: video recording; the fish, which is a resident territorial owner, is oriented towards a cage containing an intruder (on the right, not visible). The oscillogram (top right panel) and spectrogram (bottom right panel) of the emitted sound show a train of pulses followed by a tonal segment.

This Aedes aegypti mosquito is infected with Wolbachia pipientis. As a result, its proboscis bends on skin and similar surfaces, rather than penetrating them.
