ITHACA, N.Y. -- Cornell University researchers have demonstrated a novel method of separating DNA molecules by length. The technique might eventually be used to create chips or other microscopic ...

Engineers dream of using nanoparticles to build designer materials, and the new theory can help guide efforts to make nanoparticles assemble into useful structures. The theory explains earlier results ...

Chromosomes are not distributed randomly in nuclei. Appropriate positioning can activate (or repress) genes by bringing them closer to active (or inactive) compartments like euchromatin (or ...

This is a preview. Log in through your library . Abstract Entropy alone can self-assemble hard nanoparticles into colloidal crystals of remarkable complexity whose structures are the same as atomic ...

An Associate Professor in Physics at the University of Portsmouth in the UK believes that gravity could be explained by information-reducing processes inside a computational or simulated universe. Dr ...

PHILADELPHIA – In an experiment with exquisite sensitivity, physicists at the University of Pennsylvania have found that fluctuations as fleeting as the bending of rod-shaped viruses just 880 ...

reported in the journal Physical Review Letters. Led by graduate student Keng-hui Lin, scientists in the laboratory of Penn physicist Arjun G. Yodh measured the entropic forces exerted by rod-like ...
