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 ...
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 ...
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 ...
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 ...
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 ...
During his life, Albert Einstein made some of the world’s greatest scientific discoveries. However, the location of his brain, which was controversially removed by the pathologist Dr Thomas Harvey upon Einstein’s death in ...
The United Nations has declared 2005 the International Year of Physics - and there's a very good reason why this particular year was chosen to raise worldwide public awareness of physics. It is also the 100th anniversary ...
