Marveling over ‘molecular chicken wire’
VANDERBILT (US)—The hottest, thinnest, toughest new material in physics and nanotechnology is graphene: a remarkably flat molecule made of carbon atoms arranged in hexagonal rings much like molecular chicken wire. (more…)

Quantum dots catch cancer early
In this illustration, quantum dots are depicted as gold spheres that attract DNA strands linked to cancer risks. When the quantum dots are exposed to certain types of light, they transfer the energy to fluorescent molecules, shown as pink globes, that emit a glow. This enables researchers to detect and count the DNA strands linked to cancer. (Credit: Yi Zhang/ Johns Hopkins University)
