Nanoparticle QR code as banknote security feature (w/video)

An invisible quick response (QR) code has been created by researchers in an attempt to increase security on printed documents and reduce the possibility of counterfeiting, a problem which costs governments and private industries billions of pounds each year.

Molecular beacons light up stem cell transformation

In a new study, Brown University researchers demonstrate a new tool for visually tracking in real-time the transformation of a living population of stem cells into cells of a specific tissue. The 'molecular beacons', which could advance tissue engineering research, light up when certain genes are expressed and don't interfere with the development or operation of the stem cells.

Quantum longitude - keeping track of qubits in the quantum sea

Quantum computing depends exquisitely on the parts of a quantum system remaining coherent long enough---even in the face of environmental noise---for the computation to be performed. A proposed scheme should be helpful in sustaining coherence by carefully making mid-calculation corrections.

DNA origami for assembling nanomachines

In cooperation with his research group at the University of Kyoto and his partners in Freiburg, Prof. Dr. Osamu Tabata, microengineer and External Senior Fellow at the Freiburg Institute for Advanced Studies (FRIAS) is working on the development of a new generation of micromachines based on folded DNA molecules that is smaller, more intelligent and better than the previous generation.
