Âé¶¹ÒùÔºicists create artificial cricket hairs

Scientists have re-created one of nature's most sensitive sound detectors – the tiny hairs found on body parts of crickets, which allow them to hear predators and make an escape before they get close enough to catch them. ...

Motor Transport in Bio-Nano Systems

Molecular motors are nanoscale engines which move along very thin rod-like filaments and, in this way, drive the heavy traffic of molecular cargo within biological cells. Both motors and filaments can be isolated from the ...

Scientists use new simulation methods to observe single events of membrane fusion with molecular resolution

The fusion of membranes is essential for many processes in the human body, for instance, in the communication between nerve cells. A single fusion event occurs on the nanometer scale and takes less than a millisecond. Using ...

Âé¶¹ÒùÔºicists discover temperature key to avalanche movement

100 years after Einstein's landmark work on Brownian motion, physicists have discovered a new concept of temperature that could be the key to explaining how ice and snow particles flow during an avalanche, and could lead ...

Scientists close in on 'superbrakes' for cars

A theoretical study of friction between solids that looks at the process just one molecule at a time could soon lead to a more effective way to stop cars in an emergency than simply slamming on the brakes or using ABS. Scientists ...

Optical tweezers to prove Einstein right

100 years after Einstein’s landmark paper, optical tweezer technology could confirm the theory of classical Brownian motion in details that Einstein missed when he first proposed it a century ago. This research is reported ...
