New method of mass-producing high-quality DNA molecules

A new method of manufacturing short, single-stranded DNA molecules can solve many of the problems associated with current production methods. The new method, which is described in the scientific periodical Nature Methods, can be of value to both DNA nanotechnology and the development of drugs consisting of DNA fragments.

Building 3D fractals on a nano scale

It starts with one 3D structure with eight planes, an octahedron. This repeats itself to smaller octahedra: 625 after just four steps. At every corner of a new octahedron, a successive octahedron is formed. A truly fascinating 3D fractal ‘building' is formed on the micro and nano scale. It can be used for high performance filtering, for example. Scientists of the MESA+ Institute for Nanotechnology of the University of Twente in The Netherlands present these structures in the Journal of Micromechanics and Microengineering (JMM).

Atom by Atom, Bond by Bond, a Chemical Reaction Caught in the Act

Berkeley Lab scientists make the first-ever high-resolution images of a molecule as it breaks and reforms chemical bonds

The single-atom tip of the noncontact atomic force microscope “feels” changes in the strength of electronic forces as it moves across the surface at a constant height. Resulting movements of the stylus are detected by a laser beam to compute images.

Stanford scientists develop high-efficiency zinc-air battery

Stanford University scientists have developed an advanced zinc-air battery with higher catalytic activity and durability than similar batteries made with costly platinum and iridium catalysts. The results, published in the May 7 online edition of the journal Nature Communications, could lead to the development of a low-cost alternative to conventional lithium-ion batteries widely used today.
