A magnetic pendulum
Article Abstract:
A beautiful demonstration of a magnetic domain wall oscillating just as a pendulum would do under gravity is provided. By trapping a single magnetic domain wall in a strip of ferromagnetic material, it is shown that they can force the oscillations of the wall inside this potential well, achieving resonant displacements of micrometre length at megahertz frequencies with moderate currents.

Saturn's moon Phoebe as a captured body from the outer Solar System
Article Abstract:
The orbital properties of Phoebe, one of Saturn's irregular moons suggests that the ringed planet's gravitational field captured it. It is stated that Phoebe's composition is close to that derived for other solar nebula bodies such as Triton and Pluto and different from other satellites of Saturn supporting Phoebe's origin as a captured body from the outer solar system.

The weight of expectation
Article Abstract:
Sir Isaac Newton developed his universal law of gravitation as it applies to planets. However, the question arises as to whether it works at small scales. An investigation for a deviation from the anticipated behavior might supply the initial evidence in support of string theory.
