An extreme distortion of the Van Allen but arising from the 'Hallowe'en' solar storm in 2003
Article Abstract:
The Earth's radiation belts known as the Van Allen belts contain high-energy electrons trapped on magnetic field lines, the outer Van Allen belt as on 2003 was compressed dramatically by a solar storm know as the 'Hallowe'en storm'. The extreme distortion and displacement of the outer radiation belt during the Hallowe'n storm was associated with a major reduction of the Earth's plasmasphere.

Cavity cooling of a microlever
Article Abstract:
Experimental evidence for passive optical cooling of a micro mechanical resonator is presented. Cavity-induced photothermal pressure is developed to quench the brownian vibrational fluctuations of a gold-coated silicon microlever from room temperature down to an effective temperature of 18 K.

Bismuth embrittlement of copper is an atomic size effect
Article Abstract:
Embrittlement by the segregation of impurity elements to grain boundaries is one of a small number of phenomena that can lead to metallurgical failure by fast fracture. The different ways in which minute traces of bismuth in copper cause ductile metal to fail in a brittle manner is explored.
