Optically transparent water oxidation catalyst made from copper nanowires

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.

Nanomechanical cantilever sensory array: The Rosetta Stone for antibiotic resistance?

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'.

1,2,3, many - how few particles turn into a 'heap'

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'.
