Low-resistance connections facilitate multi-walled carbon nanotubes for interconnects: Hybrid electronics

Using a new method for precisely controlling the deposition of carbon, researchers have demonstrated a technique for connecting multi-walled carbon nanotubes to the metallic pads of integrated circuits without the high interface resistance produced by traditional fabrication techniques.

First X-ray View of Martian Soil
This graphic shows results of the first analysis of Martian soil by the Chemistry and Mineralogy (CheMin) experiment on NASA's Curiosity rover. The image reveals the presence of crystalline feldspar, pyroxenes and olivine mixed with some amorphous (non-crystalline) material. The soil sample, taken from a wind-blown deposit within Gale Crater, where the rover landed, is similar to volcanic soils in Hawaii. The colors in the graphic represent the intensity of the X-rays, with red being the most intense.

Microfluidic Breakthroughs Offer New Options for Ease and Accuracy in Extraction of Rare Cells or Separating Blood

Using something called "inertial microfluidics," University of Cincinnati researchers are able to continuously and selectively collect rare cells, such as circulating tumor cells, based on their size vs. other biomarkers. This could reduce analysis time and increase selectivity while reducing reliance on antibody-based testing in clinical tests.
