How the Venus flytrap snaps

Article Abstract:

Previous studies that have focused on the biochemical response of the trigger hairs to stimuli and quantified the propagation of action potentials in the leaves is complemented by considering the post-stimulation mechanical aspects of Venus flytrap closure. It is shown that the fast closure of the trap results from a snap-buckling instability, the onset of which is controlled actively by the plant.

A planet that blinks

Article Abstract:

Spitzer Space Telescope, the largest space-based infrared telescope, with an aperture of 85 cm has measured the infrared light of the two different planets circling the Sun without any specialized starlight suppressing instrumentation. This infrared radiation from these planets is measured from the dip in total light as the planets pass behind their parent stars.
