This shows the nanomanipulation of an artificial atom.

T-cells (red) are activated more robustly when they interact with artificial antigen-presenting cells (green) that are elongated (right) versus round (left).

A composite material created at Rice University is nearly impervious to gas and may lead to efficient storage of compressed natural gas for vehicles. A 65-micrometer-wide polymer film, photographed edge-on with an electron microscope, contains a tiny amount of enhanced graphene nanoribbons that present gas molecules a “tortuous path” to escape.

An initiated chemical vapor deposition (ICVD) system is used to convert a mixture of gases into foam polymer.

The beautiful, petal-like shells of galaxy PGC 6240 are captured here in intricate detail by the NASA/ESA Hubble Space Telescope, set against a sky full of distant background galaxies. This cosmic bloom is of great interest to astronomers due to both its uneven structure, and the unusual clusters of stars that orbit around it — two strong indications of a galactic merger in the recent past.

A super-resolution technique developed at Rice University allows fluorescent-labeled probe DNA to pinpoint target DNA sequences in an immobilized strand in ways neither regular nor electron microscopes are able. The technique relies on multiple images of probes binding temporarily to targets as they flow over the strand and are captured by a camera.

ESO’s Very Large Telescope (VLT) has captured a remarkably detailed image of the Toby Jug Nebula, a cloud of gas and dust surrounding a red giant star. This view shows the characteristic arcing structure of the nebula, which, true to its name, does indeed look a little like a jug with a handle.
