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).

Bright Points in Sun's Atmosphere Mark Patterns Deep In Its Interior
Brightpoints in the sun's atmosphere, left, correspond to magnetic parcels on the sun's surface, seen in the processed data on the right. Green spots show smaller parcels, red and yellow much bigger ones. Images based on data from NASA's SDO captured at 8 p.m. EDT on May 15, 2010.
