Microfluidic device for rapid TB diagnosis— On this 2.5- by 7.5-cm cartridge, DNA extracted from sputum samples is amplified in the chambers on the left. TB-specific sequences are magnetically labeled in the microfluidic mixing channels in the center and detected by passage through the micro-NMR coil on the right.

Cotton Candy Nebula - The nebula known as N11, complete with sparkly star clusters embedded in fluffy pink clouds of gas. This exceptionally energetic star-forming region, also known as the Bean Nebula, extends over 1,000 light-years in the Large Magellanic Cloud. Three generations of star formation have created shells of gas and dust which are being blown away by radiation from the newborn stars.
