Nanoscale 'spaghetti' could become tools of regenerative medicine

Medicine's recipe for keeping older people active and functioning in their homes and workplaces - and healing younger people injured in catastrophic accidents - may include "noodle gels" and other lab-made invisible filaments that resemble uncooked spaghetti with nanoscale dimensions.

New nano-measurements add spark to centuries-old theory of friction

The phenomenon of friction, when studied on a nanoscale, is more complex than previously thought. When friction occurs, an object does not simply slide its surface over that of another, it also makes a slight up-and-down movement. This finding completes a centuries-old theory of friction dating to 1699 and uncovers a gap in contemporary thinking on friction.

Single molecules in a quantum movie

The quantum physics of massive particles has intrigued physicists for more than 80 years, since it predicts that even complex particles can exhibit wave-like behaviour - in conflict with our everyday ideas of what is real or local. An international team of scientists now succeeded in shooting a movie which shows the build-up of a matter-wave interference pattern from single dye molecules which is so large (up to 0.1 mm) that you can easily see it with a camera.
