X-rays stream off the sun in this image showing observations from by NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, overlaid on a picture taken by NASA's Solar Dynamics Observatory (SDO).

- The bio-based filter of nano-cellulose is to be used for the first time in real-life situations and tested within a process industry and in municipal wastewater treatment in Spain. Other industries have also shown interest in this technology and representatives of the mining industry have contacted me and I have even received requests from a large retail chain in the UK, says Aji Mathew Associate Professor, Division of Materials Science at Luleå University.

The researchers found that gelatin nanoparticles could be laced with medications for delivery to the brain, and that they could extend the treatment window for when a drug could be effective. Gelatin is biocompatible, biodegradable, and classified as "Generally Recognized as Safe" by the Food and Drug Administration. Once administered, the gelatin nanoparticles target damaged brain tissue thanks to an abundance of gelatin-munching enzymes produced in injured regions.

A picture of a membrane protein called cysZ determined with Phenix software using data that could not previously be analyzed.

Rice University researchers fabricated a three-pixel, CIS-based optoelectronic sensor array to test the two-dimensional compound's ability to capture image information. They started with few-layer exfoliated CIS on a silicon substrate, fabricated three pairs of titanium/gold electrodes on top of the CIS and cut the CIS into three sections with a focused ion beam.

Rocker (blue ribbons and yellow sticks) is an artificially designed protein that transports zinc ions (green) across biological membranes (gray sticks) by binding zinc ions it at one end of the molecule and rearranging ('rocking') to pass them onto the other end. The protein was built by researchers from Dartmouth College and other institutions.

The famous Horsehead nebula of visible-light images (inset) looks quite different when viewed in infrared light, as seen in this newly released image from NASA's Spitzer Space Telescope.
