DNA 'cage' could improve nanopore technology
Researchers from Brown University have designed a tiny cage that can trap a single strand of DNA after it has been pulled through a nanopore. While caged, biochemical experiments can be performed on the strand, which can then be zipped back through the nanopore. The device could enable researchers to look for probe a DNA before and after a reaction takes place.

Buckyballs offer environmental benefits
Treated carbon-60 molecules have the ability to recover valuable metals from liquids, including water and potential pollutants. In testing various metals, Rice University researchers found that charge and ionic radius influence how the metals bind to the hydroxylated buckyballs.

New method for minimally invasive tissue ablation surgery
The armamentarium of minimally invasive surgery is enriched with a new tissue ablation technique that employs the finding that reversible electroporation electric pulses, a mainstay tool of 21st century biotechnology, can substantially augment the effectiveness of electrolytic tissue ablation, a minimally invasive tissue ablation technique that has been used infrequently since its discovery at the beginning of the 19th century.

Precision growth of light-emitting nanowires
A novel approach to growing nanowires promises a new means of control over their light-emitting and electronic properties. Berkeley Lab researchers demonstrated a new growth technique that uses specially engineered catalysts. These catalysts have given scientists more options than ever in turning the color of light-emitting nanowires.

Sodium carbonate capsules used to capture carbon safely
The team developed a new type of carbon capture media composed of core-shell microcapsules, which consist of a highly permeable polymer shell and a fluid (made up of sodium carbonate solution) that reacts with and absorbs carbon dioxide. Sodium carbonate is typically known as the main ingredient in baking soda. The capsules keep the liquid contained inside the core, and allow the CO2 gas to pass back and forth through the capsule shell.

Turing also present at the nanoscale
In the world of single atoms and molecules governed by chaotic fluctuations, is the spontaneous formation of Turing patterns possible -- the same ones that are responsible for the irregular yet periodic shapes of the stripes on zebras' bodies? A Polish-Danish team of physicists has for the first time demonstrated that such a process can not only occur, but can also be used for potentially very interesting applications.

Tiny robotic 'hands' could improve cancer diagnostics, drug delivery
Many people imagine robots today as clunky, metal versions of humans, but scientists are forging new territory in the field of 'soft robotics.' One of the latest advances is a flexible, microscopic hand-like gripper. The development could help doctors perform remotely guided surgical procedures or perform biopsies. The materials also could someday deliver therapeutic drugs to hard-to-reach places. The report appears in the journal ACS Applied Materials & Interfaces.

X-ray pulses uncover free nanoparticles for the first time in 3-D
For the first time, researchers have determined the three-dimensional shape of free-flying silver nanoparticles, using DESY's X-ray laser FLASH. The tiny particles, hundreds of times smaller than the width of a human hair, were found to exhibit an unexpected variety of shapes, as the physicists from the Technical University Berlin, the University of Rostock, the SLAC National Accelerator Laboratory in the United States and from DESY report in the scientific journal Nature Communications.
