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.

NASA Radar Penetrates Thick, Thin of Gulf Oil Spill

uavsar-640_0_0.jpg
NASA UAVSAR image of the Deepwater Horizon oil spill, collected June 23, 2010. The oil appears much darker than the surrounding seawater in the greyscale image. This is because the oil smoothes the sea surface and reduces its electrical conductivity, causing less radar energy to bounce back to the UAVSAR antenna. Additional processing of the data by the UAVSAR team produced the two inset color images, which reveal the variability of the oil spill's characteristics, from thicker, concentrated emulsions (shown in reds and yellows) to minimal oil contamination (shown in greens and blues). Dark blues correspond to areas of clear seawater bordering the oil slick.

Immunomodulatory effect of nanoparticles

Polymeric nanoparticles for immunotherapy represent a dynamic research field. The possibility to control their size, charge, and other surface properties provides the opportunity to affect both uptake by immune cells and induction of immunity. Dendritic cells (DC), which represent the most potent antigen-presenting cells of the immune system, are one of the main targets of current NP-based immunotherapeutic approaches against tumors.
