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.
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.
In an ongoing effort to mirror the ability of biological tissues to respond rapidly and appropriately to changing environments, scientists from the McGowan Institute for Regenerative Medicine have synthesized a single, multifunctional polymer material that can decontaminate both biological and chemical toxins.
Researchers at UC Santa Barbara have provided the first clear demonstration that the theory of quantum mechanics applies to the mechanical motion of an object large enough to be seen by the naked eye. Their work satisfies a longstanding goal among physicists.
University of Florida engineering researchers have found they can ignite certain nanoparticles using a low-power laser, a development they say opens the door to a wave of new technologies in health care, computing and automotive design.
Rice researchers, in collaboration with a team led by Gyou-jin Cho at Sunchon National University in Korea, have come up with an inexpensive, printable transmitter that can be invisibly embedded in packaging.
Fraunhofer FIT offers complete turnkey systems for biomolecular analysis, diagnosis and screening in medical and pharmaceutical research. At HANNOVER MESSE the researchers present the latest generation of their devices and imaging analysis software.
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.
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.
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.
