A molecular brake for the bacterial flagellar nanomotor

Biozentrum researchers have now discovered that Escherichia coli bacteria harness a sophisticated chemosensory and signal transduction machinery that allows them to accurately control motor rotation, thereby adjusting their swimming velocity in response to changing environments.

Power walk - harnessing energy from everyday movements

These boots are made for walking ... and for powering up your cell phone? It could happen, according to a team of Princeton and Caltech scientists. They report that they have developed an innovative rubber chip that has the ability to harvest energy from motions such as walking, running, and breathing and convert it into a power source.

Mixing ski design and nanotechnology

Imagine packing skis into a suitcase, skis that never need wax or skis that hold a perfect line in all snow conditions. That's just what University of Nevada, Reno students in Kam K. Leang's mechanical engineering senior design course do, they imagine the possibilities of design using nanotechnology.

Molecules arrange themselves into predictable patterns

The features on computer chips are getting so small that soon the process used to make them, which has hardly changed in the last 50 years, won't work anymore. One of the alternatives that academic researchers have been exploring is to create tiny circuits using molecules that automatically arrange themselves into useful patterns.

Wenn alle an der DNA zerren

Wissenschaftlern ist eine quantitative Beschreibung von DNA-Ringen gelungen, sodass nun molekulare Eigenschaften wie etwa die Steifigkeit und der DNA-Durchmesser in nanoskopische Groessen wie Form und Ausdehnung des Polymerrings uebersetzt werden koennen.
