Proofreading RNA: Structure of RNA Polymerase II's Backtracked State Print
Wednesday, 25 November 2009 00:00

For genes to be expressed, a complementary strand of RNA must be produced from a DNA template. During this process of transcription, a special class of enzyme called RNA polymerase moves along the DNA template, reading the DNA and producing an RNA complement.

X-Ray Imaging of the Dynamic Magnetic Vortex Core Deformation Print
Wednesday, 25 November 2009 00:00

Magnetic thin-film nanostructures can exhibit a magnetic vortex state in which the magnetization vectors lie in the film plane and curl around in a closed loop. At the very center of the vortex, a small, stable core exists where the magnetization points either up or down out of the plane.

Protein Bridges DNA Base and Nucleotide Excision Repair Pathways Print
Wednesday, 28 October 2009 00:00

Alkyltransferase proteins (AGT) protect cells from the biological effects of DNA damage caused by the addition of alkyl groups (alkylation). Alkyltransferase-like proteins (ATLs) can do the same, but they lack the reactive cysteine residue that allows the alkyltransferase function, and the mechanism for cell protection has remained unknown.

Harnessing the Bacterial Power of Nanomagnets Print
Wednesday, 30 September 2009 00:00

Nanometer-size magnets have wide-ranging uses, from directed cancer therapy and drug delivery systems to magnetic recording media and transducers. Such applications require the production of nanoparticles with well-controlled size and tunable magnetic properties.

Bilayer Graphene Gets a Bandgap Print
Wednesday, 26 August 2009 00:00

Graphene is the two-dimensional crystalline form of carbon whose extraordinary electron mobility and other unique features hold great promise for nanoscale electronics and photonics. But without a bandgap, graphene's promise can't be realized.

Hybrid Rotaxanes: Interlocked Structures for Quantum Computing? Print
Wednesday, 26 August 2009 00:00

Rotaxanes are mechanically interlocked molecular architectures consisting of a dumbbell-shaped molecule, the “axle,” that threads through a ring called a macrocycle. Because the rings can spin around and slide along the axle, rotaxanes are promising components of molecular machines.

Stochastic Domain-Wall Depinning in Magnetic Nanowires Print
Wednesday, 29 July 2009 00:00

Reliably controlling the motion of magnetic domain walls along magnetic nanowires is a key requirement for current technological development of novel classes of logic and storage devices, but understanding the nature of non-deterministic domain-wall motion remains a scientific challenge.

Protein Structure Suggests Role as Molecular Adapter Print
Wednesday, 24 June 2009 00:00

To split and copy DNA during replication, all cellular organisms use a multicomponent molecular machine known as the replisome. An essential step in replisome assembly is the loading of ring-shaped helicases (motor proteins) onto the separated strands of DNA.

Observation of a Macroscopically Quantum-Entangled Insulator Print
Wednesday, 27 May 2009 00:00

It has recently been proposed that insulators with large band gaps and strong spin-orbit coupling can host a new phase of quantum matter called a topological insulator that is characterized by entangled wavefunctions.

How Dynein Binds to Microtubules Print
Wednesday, 29 April 2009 00:00

Cytoplasmic dynein is a protein complex responsible for the transport of a large variety of cargoes, from specific RNAs and proteins to whole organelles, in a directional fashion along microtubules that serve as cellular conveyor belts.

Preservation of Fe(II) by Carbon-Rich Matrices in Hydrothermal Plumes Print
Wednesday, 29 April 2009 00:00

There are large regions of the global ocean where iron availability is so low that it limits life. Oceanographers have long explained this anomaly by assuming that the iron in the sea is primarily incorporated as Fe(III) into inorganic minerals.
