Hydrogen is used as an energy source in fuel cells and can be produced from water by using sunlight and a suitable catalyst. Researchers have now introduced a new electrocatalyst consisting of a conductive network of core-shell nanowires that is just as efficient as conventional metal oxide films on indium tin oxide (ITO) and a great deal more transparent and robust.

Scientists developed a novel nanomechanical technique to confront the problem of antibiotic resistance. According to Dr. Joseph Ndieyira, one of the developers involved in the technique, 'The use of this technology will allow scientists to understand how antibiotics work, how bacteria develop resistance, and what molecular mechanisms could be exploited to get around their defense mechanisms'.

How large does a group of particles have to be to render moot its exact number of particles? In experiments using ultracold atoms, Heidelberg physicists succeeded in observing the transition to a many-body system well described by an infinite number of particles. In philosophy, this problem is known as the sorites paradox. The essential question is when a collection of elements forms a 'heap'.

Theoretical physicists have developed a mathematical model for a type of microscopic test lab that could provide new and deeper insight into the world of quantum particles. The new test system will enable the simultaneous study of one hundred light quanta (photons) and their complex quantum mechanical relationships ('quantum entanglement') - a far greater number than was previously possible.

Princeton University researchers found that the 'landscape' of quantum control - a representation of quantum mechanics that allows the dynamics of atoms and molecules to be manipulated - can be unexpectedly simple, which could allow for ready control of quantum operating devices at the nanoscale.
