Guiding the random laser

At its most basic level, a random laser is precisely what its name implies; random. So, how do you control some of the randomness to make useful devices? It's a question that's led a team of researchers to a discovery that's taking laser technology to the next level.

Graphene sensors detect HIV DNA

Next generation graphene electronic biochemical sensor devices are able to detect very low amounts of HIV DNA thanks to their very low electronic noise.

Heavy metal thunder: Protein can be switched on to conduct electricity like a metal

About four years ago, a research team got a lab result that even he couldn't quite believe. As with most scientific surprises, it goes against all conventional wisdom: the first evidence of a protein that could conduct electricity like a metal.

Researchers discover switching function in molecular wire

Researchers have developed a molecule integrating a wire with a diameter of only a single atom. They discovered that the current can be regulated via this molecular wire.

New technique produces tunable, nanoporous materials

Researchers describe a new technique for creating novel nanoporous materials with unique properties that can be used to filter molecules or light.

Nanomagnets levitate thanks to quantum physics

Scientists show that, despite Earnshaw's theorem, nanomagnets can be stably levitated in an external static magnetic field owing to quantum mechanical principles. The quantum angular momentum of electrons, which also causes magnetism, is accountable for this mechanism.
