The use of a different resonance in atomic force microscopy enhances resolution
Atomic force microscopy (AFM) is a highly sensitive form of microscopy that makes it possible to map a surface with near-atomic resolution. Shaw Wei Kok and colleagues from A*STAR’s Singapore Institute of Manufacturing ...

Study reveals new role for RNA interference during chromosomal replication
At the same time that a cell's DNA gets duplicated, a third of it gets super-compacted into repetitive clumps called heterochromatin. This dense packing serves to repress or "silence" the DNA sequences within -- which could ...

Vibrating nanoparticles interact: Placing nanodisks in groups can change their vibrational frequencies
Like a tuning fork struck with a mallet, tiny gold nanodisks can be made to vibrate at resonant frequencies when struck by light. In new research, Rice University researchers showed they can selectively alter those vibrational ...
