A novel microfluidics platform allowed viewing of structural details of rotavirus double-layered particles; the 3-D graphic of the virus, in purple, was reconstructed from data gathered by the new technique.

This false-color composite image, constructed from data obtained by NASA's Cassini spacecraft, shows Saturn's rings and southern hemisphere. The composite image was made from 65 individual observations by Cassini's visual and infrared mapping spectrometer in the near-infrared portion of the light spectrum on Nov. 1, 2008. The observations were each six minutes long.

NASA/JPL's popular mobile app continues to amass many exciting images including the Mars Curiosity Rover, dying stars, moons of Saturn and giant asteroids.

This image shows a novel bifunctional catalyst for the Mannich reaction.

The giant star Zeta Ophiuchi is having a "shocking" effect on the surrounding dust clouds in this infrared image from NASA's Spitzer Space Telescope. Stellar winds flowing out from this fast-moving star are making ripples in the dust as it approaches, creating a bow shock seen as glowing gossamer threads, which, for this star, are only seen in infrared light.

These nanoparticles created by MIT engineers can act as synthetic biomarkers for disease. The particles (brown) are coated with peptides (blue) that are cleaved by enzymes (green) found at the disease site. The peptides then accumulate in the urine, where they can be detected using mass spectrometry.

Two different protein cages, cowpea chlorotic mottle virus (blue) and Pyrococcus furiosus ferritin (red), can be used to guide the assembly of binary nanoparticles superlattices through tunable electrostatic interactions with charged gold nanoparticles (yellow).
