'Motorized' DNA opens door to autonomous molecular experiments


Using the same protein molecule that scientists have used for decades to copy genetic material, researchers have developed a molecular motor for propelling DNA.
The work demonstrates the ability to precisely control the motion of billions of DNA molecules at once and, through external stimuli, confer autonomous decision-making that sets the stage for massive, but greatly miniaturized experimental systems.

Researchers study signaling networks that set up genetic code


In a new study, researchers at the University of Illinois have identified and visualized the signaling pathways in protein-RNA complexes that help set the genetic code in all organisms. The genetic code allows information stored in DNA to be translated into proteins.

Strings Link the Ultracold with the Superhot

From Science News:

So string theory has long remained in the physics version of The Twilight Zone, disconnected from the ordinary world of sight and sound. But now the extra-dimensional math has begun to audition for Reality TV. For the first time, superstring theorists can point to a place where their formulas help other physicists understand something they can see in their experiments.

Keep on spinning: A persistent spin state that could revolutionize spintronics


By controlling the collective spin state of highly mobile electrons in semiconductors, researchers in the Materials Sciences Division (MSD) at the U.S. Department of Energy's Lawrence Berkeley National Laboratory have taken a major step forward in the technology of spintronics. At the same time they have discovered a new conservation law, an important advance in fundamental physics.
