A simple artificial material can influence the properties of visible light

Metamaterials can be used to manipulate light for a range of applications, but often require complicated three-dimensional structures with features as small as a few tens of nanometers. Now, researchers have constructed a simpler, two-dimensional metasurface for state-of-the-art high-transmission light manipulation.

Scientists demonstrate basics of nucleic acid computing inside cells

Using strands of nucleic acid, scientists have demonstrated basic computing operations inside a living mammalian cell. The research could lead to an artificial sensing system that could control a cell's behavior in response to such stimuli as the presence of toxins or the development of cancer.
