Drill Here? NASA's Curiosity Mars Rover Inspects Site
NASA's Curiosity Mars rover has driven within robotic-arm's reach of the sandstone slab at the center of this April 23 view from the rover's Mast Camera. The rover team plans to have Curiosity examine a target patch on the rock, called "Windjana," to aid a decision about whether to drill there.

Gold nanoparticles help target, quantify breast cancer gene segments in a living cell
A single gold nanoparticle, or monomer, appears green when illuminated (top left), while a pair of gold nanoparticles bound to an mRNA splice variant, or dimer, appears reddish (top right). Monomers and dimers also scatter light differently, as shown in the graph above.

Atomic switcheroo explains origins of thin-film solar cell mystery
Cross-sectional electron beam-induced current maps show the difference in cadmium telluride solar cells before (pictured above) and after (below) cadmium chloride treatment. The increased brightness after treatment indicates higher current collection at the grain boundaries.

Berkeley Lab Researchers Demonstrate First Size-based Chromatography Technique for the Study of Living Cells
With size-based chromatography, a hexagonally ordered array of gold nanoparticles is fabricated onto a hybrid live cell-supported membrane. Membrane components move freely through the array provided they don’t exceed its physical dimensions. This reveals organizational aspects of the membrane environment unobservable by other techniques.

Amino-functionalized carbon nanotubes act as a carrier for nerve growth factor
Under inverted fluorescence microscope, the multi-walled carbon nanotubes-ethylenediamine-nerve growth factor complexes significantly induce PC12 cell differentiation, and the growing protuberances are long, dense, and woven into meshes (× 200).
