Metasurfaces are two-dimensional (2-D) metamaterials that can control scattering waves of a light beam. Their applications include thin-sheet polarizers, beam splitters, beam steerers and lenses. These structures can control ...
Deep beneath the Earth's surface, oil and groundwater percolate through gaps in rock and other geologic material. Hidden from sight, these critical resources pose a significant challenge for scientists seeking to evaluate ...

A team of researchers at the Max Planck Institute for Evolutionary Anthropology has found evidence that suggests there has been no long-term removal of Neandertal DNA from modern Europeans. In their paper published in Proceedings ...
IBM scientists recently discovered that a drop of oil doesn't look like a drop at all if it is small, to the scale of one billionth of a billionth of a liter, or attoliter. Rather, a nanoscale oil droplet looks more like ...
