Offshore use of vertical-axis wind turbines gets closer look Posted: 30 Jul 2012 05:46 PM PDT Wind energy researchers are re-evaluating vertical axis wind turbines (VAWTs) to help solve some of the problems of generating energy from offshore breezes.

Interactive proofs: Ten-year-old problem in theoretical computer science falls Posted: 30 Jul 2012 09:42 AM PDT Interactive proofs -- mathematical games that underlie much modern cryptography -- work even if players try to use quantum information to cheat. Computer scientists show there are multiprover interactive proofs that hold up against entangled respondents.

The atomic nucleus: Fissile liquid or molecule of life? Posted: 30 Jul 2012 06:49 AM PDT A new view of the nucleus that unifies its liquid and molecule-like aspects has now been put forward.  By making an analogy with neutron stars, the researchers have for the first time demonstrated one of the necessary conditions for the formation of molecule-like behavior within the atomic nucleus. Such molecule-like behavior makes it possible to understand the synthesis of elements that are key to the appearance of life.

A giant step in a miniature world: Electrical charge of nano particles measured Posted: 30 Jul 2012 06:48 AM PDT Scientists have developed a new method that measures not only the size of the particles but also their electrostatic charge. Up until now it has not been possible to determine the charge of the particles directly. This unique method, which is the first of its kind in the world, is just as important for the manufacture of drugs as in basic research.

Lotus leaf inspires fog-free finish for transparent surfaces Posted: 30 Jul 2012 06:41 AM PDT Chinese scientists use silica nanoparticles resembling raspberries to create a water-repellent, fog-free, self-cleaning finish for glass and other transparent surfaces.

Mathematicians develop new method for describing extremely complicated shapes Posted: 30 Jul 2012 06:41 AM PDT Building a bridge between topology and fractals may lead to a new way of describing tiny defects in metal or the froth of a breaking wave.

How to avoid traps in plastic electronics Posted: 30 Jul 2012 06:41 AM PDT Plastic electronics hold the promise of cheap, mass-produced devices. But plastic semiconductors have an important flaw: the electronic current is influenced by "charge traps" in the material. New research reveals a common mechanism underlying these traps and provides a theoretical framework to design trap-free plastic electronics.
