How and why of vesicle formation
Article Abstract:
Research on the process of vesicle formation in monolayer and bilayer membranes is one of the few areas of molecular biology in which quantitative methods and solutions used in physics are finding extensive application. Studies of this sort have greatly advanced scientists' knowledge of the budding process on cell surfaces, mainly through concepts and theories touching on topics such as the bending energy in membranes, cell shape calculation, the links of membrane molecular components and free energy. Despite the great strides achieved in the physics of the process, the chemical aspect of the problems remains far from elucidation.

Natural antidote to global warming?
Article Abstract:
An engineered return of the Maunder minimum, when the sun lacked sunspots, is proposed to be an antidote to the threat of global warming. This theory is based on interference between cosmic radiation and ultraviolet radiation from the Sun, resulting in the decrease of cosmogenic isotope production. The Maunders minimum can be identified by extra 12C in tree-rings and extra 10Be in ice cores from the period. The Maunder minimum is the period from 1645 to 1715, after which Galileo first observed the black spots on the surface of the Sun.

The wonders of the microlaser
Article Abstract:
A group of scientists at the Massachusetts Institute of Technology (MIT) have constructed a new laser which functions even when there is less than one photon in the optical cavity. Lasers exhibit high efficiency only when there is a large number of photons in the optical cavity. This new type of laser, called the 'microlaser,' uses the principle of the previously developed one-atom laser. The microlaser consists of only one atom in an ideally reflecting optical cavity made of two highly polished convex mirrors.
