One day soon a biosensing nanodevice may eliminate long lines at airport security checkpoints and revolutionize health screenings for diseases like anthrax, cancer and antibiotic resistant Staphylococcus aureus (MRSA). Even more incredible than the device itself, is that it is based on the world's tiniest rotary motor: a biological engine measured on the order of molecules. --by Margaret Coulombe (Read the full text in SOLS News)

Scientists at ASU have developed the world’s first gene detection platform made up entirely from self-assembled DNA nanostructures. The structures are made using "DNA origami" techniques to create spatially addressable nanoarrays. The work could have broad implications for gene chip technology and may also revolutionize the way in which gene expression is analyzed in a single cell. --by Joe Caspermeyer

The unknown health and environmental effects of
nanotechnology are a bigger worry for scientists than for the public,
according to a new report. --by Skip Derra
