Synthetic nano-bio architecture for nanocatalytic photon-to-hydrogen conversion

Researchers demonstrate that a minimalistic cell-free strategy for production of artificial transmembrane protein complexes can be employed as a chassis for the construction of functional bionanoarchitectures capable of catalyzing photon-energy-to-hydrogen transformation.

New prospects for universal memory - high speed of RAM and the capacity of flash

Researchers have found a way to control oxygen concentration in tantalum oxide films produced by atomic layer deposition. These thin films could be the basis for creating new forms of nonvolatile memory.

How close are we to a real Star Trek-style medical tricorder? (w/video)

Two teams were recently awarded the Qualcomm Tricorder X Prize for developing handheld devices that can diagnose a range of diseases and check a patient's vital signs without invasive tests - inspired by Star Trek's medical 'tricorder' device.

Researchers send DNA on sequential, and consequential, building mission

A team of scientists has developed a method to create structures whose building blocks are a millionth of a meter in size by encoding DNA with assembly instructions.

Bacteria free themselves with nano-spearguns

Many bacteria are armed with nano-spearguns, which they use to combat unwelcome competitors or knockout host cells.

Piezoelectric nanogenerators for self-powered flexible sensors

Researchers have demonstrated a high performance flexible piezoelectric nanogenerator based on a piezoelectrically enhanced nanocomposite micropillar array of BaTiO3 nanoparticles embedded into a highly crystalline polymer for efficient energy harvesting and highly sensitive self-powered sensing.

A skyrmion square dance

Applying a magnetic field can switch a grid of magnetic vortices between triangular and square arrangements.
