Recently, researchers from Boston University and the Smithsonian Tropical Research Institute in Panama have been taking a closer look at the vibrations that red-eyed treefrog embryos use as cues to trigger early hatching. They discovered that treefrog embryos can evaluate different features of vibrations.

A device for damping vibrations in a drive train, in particular for plug screws in the pulp and paper industries. The device is principally characterized in that a cylindrical shaft, preferably designed as a hollow shaft, is provided, wherein the cylindrical shaft is arranged between the halves of a coupling and at least one ring having friction surfaces is arranged around the cylindrical shaft. Stick-slip vibrations that occur can thereby be favorably eliminated, and thus the gearbox and the motor of the drive train can be protected.

This tool, which is in particular a hammer, comprises a gripping handle, a striking head, and an intermediate shaft extending the handle and supporting the head, whereas the handle comprises a tube in which the shaft partially extends, this tube and this shaft being made from a rigid material presenting a first hardness. This shaft has a radial area bearing against the tube, with interposition of a link part, for absorbing vibrations, made from flexible material presenting a second hardness that is much lower than the first hardness, and a free terminal area, not covered by the link part, radially separated from the walls of the tube so as to be able to vibrate freely in an internal volume of the tube.

Who knew trouble could be such fun?

The report claims that the development could help seismologists detect earthquakes of even very small magnitude, signals of which were earlier drowned in the cacophony produced by various activities.

Vibrations play an important role in insect behaviour. In bees, vibrations are used in a variety of contexts including communication, as a warning signal to deter predators and during pollen foraging. However, little is known about how the biomechanical properties of bee vibrations vary across multiple behaviours within a species. In this study, we compared the properties of vibrations produced by Bombus terrestris audax (Hymenoptera: Apidae) workers in three contexts: during flight, during defensive buzzing, and in floral vibrations produced during pollen foraging on two buzz-pollinated plants (Solanum, Solanaceae). Using laser vibrometry, we were able to obtain contactless measures of both the frequency and amplitude of the thoracic vibrations of bees across the three behaviours. Despite all three types of vibrations being produced by the same power flight muscles, we found clear differences in the mechanical properties of the vibrations produced in different contexts. Both floral and defensive buzzes had higher frequency and amplitude velocity, acceleration, and displacement than the vibrations produced during flight. Floral vibrations had the highest frequency, amplitude velocity and acceleration of all the behaviours studied. Vibration amplitude, and in particular acceleration, of floral vibrations has been suggested as the key property for removing pollen from buzz-pollinated anthers. By increasing frequency and amplitude velocity and acceleration of their vibrations during vibratory pollen collection, foraging bees may be able to maximise pollen removal from flowers, although their foraging decisions are likely to be influenced by the presumably high cost of producing floral vibrations.
