Scientists have found evidence that double layers of graphene have a property that may let them conduct current completely without resistance. They probed the band structure at BESSY II with extremely high resolution ARPES and could identify a flat area at a surprising location.

Scientists have developed a technique for preventing the extraction of finger vein patterns from photographs. The technique involves the wearing of a clear sticker on the finger. It can prevent unwanted extraction of finger vein patterns from photographs while maintaining the convenience of finger vein authentication without having to remove the sticker.
