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.

The artistic concept shows NASA's planet-hunting Kepler spacecraft operating in a new mission profile called K2. Using publicly available data, astronomers have confirmed K2's first exoplanet discovery proving Kepler can still find planets.

A team at Cornell University led by postdoctoral associate John Heron, who works jointly with Darrell Schlom, professor of Industrial Chemistry in the Department of Materials Science and Engineering, and Dan Ralph, professor of Physics in the College of Arts and Sciences, has made a breakthrough in that direction with a room-temperature magnetoelectric memory device. Equivalent to one computer bit, it exhibits the holy grail of next-generation nonvolatile memory: magnetic switchability, in two steps, with nothing but an electric field.
