Scientists used mice to study how nerve cells in thalamic reticular nucleus work during sleep and how they help the brain concentrate.

This image shows a close-up view of the next-generation microshutter arrays — designed to accommodate the needs of future observatories — during the fabrication process.

These images show a diamond sample with a hemispherical lens (right and lower left), and the location of a single electron spin/quantum state visible through its light emission (upper left). The scale bar on the image at upper left measures five microns, the approximate diameter of a red blood cell.

The SeaWinds scatterometer on NASA's QuikScat satellite stares into the eye of 1999's Hurricane Floyd as it hits the U.S. coast. The arrows indicate wind direction, while the colors represent wind speed, with orange and yellow being the fastest.

Rice and Osaka researchers have come up with a simple method to find contaminants on atom-thick graphene. By putting graphene on a layer of indium phosphide, which emits terahertz waves when excited by a laser pulse, they can measure and map changes in its electrical conductivity.

Postdoctoral research associate Monojit Bag (left) and graduate student Tim Gehan (right) synthesize polymer nanoparticles for use in organic-based solar cells being made at the University of Massachusetts Amherst-based energy center. Deep purple nanoparticles are forming in the small glass container above Gehan's left hand.

A DNA molecule passes through a nanopore in a sheet of molybdenum disulfide, a material that researchers have found to be better than graphene at reading the DNA sequence.
