New and Improved Model of Molecular Bonding from Researchers at Berkeley Lab´s Molecular Foundry Material properties and interactions are largely determined by the binding and unbinding of their constituent molecules, but the standard model used to interpret data on the formation and rupturing of molecular bonds suffers from inconsistencies. A collaboration of researchers led by a scientist at the U.S Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley...

The binding of proteins to various substrates in a biological system is a basic but essential process to maintain the function of living things. The mechanisms underlying protein binding have been the focus of theoretical and experimental research for many years. Many mechanisms have been proposed and characterized, including "lock and key", "induced fit", "population shift" and "fly-casting". The recently discovered "fly-casting" mechanism allows a protein chain to unfold and extend to reach...

By Todd, Brian A Parsegian, V Adrian; Shirahata, Akira; Thomas, T J; Rau, Donald C ABSTRACT By combining single-molecule magnetic tweezers and osmotic stress on DNA assemblies, we separate attractive and repulsive components of the total intermolecular interaction between multivalent cation condensed DNA. Based on measurements of several different cations, we identify two invariant properties of multivalent cation-mediated DNA interactions: repulsive forces decay exponentially with a 2.3 +-...

DUBLIN (Reuters) - An Irish technology firm issued a challenge to the world's scientific community on Friday to give its verdict on technology it says smashes one of the basic laws of physics by producing "free energy." Dublin-based Steorn said it had placed an advertisement in The Economist magazine seeking 12 top physicists to examine the technology -- based on the interaction of magnetic fields -- and publish their results. "We fully accept there is going to be cynicism...
