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.

Even with defects, graphene is strongest material in the world

In a new study, researchers demonstrate that graphene, even if stitched together from many small crystalline grains, is almost as strong as graphene in its perfect crystalline form. This work resolves a contradiction between theoretical simulations, which predicted that grain boundaries can be strong, and earlier experiments, which indicated that they were much weaker than the perfect lattice.

Building 3D fractals on a nanoscale

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 nanoscale.
