Rendering of the near–perfect crystal structure of the yttrium–iron–aluminum compound used in the study. The two–dimensional layers of the material allowed the scientists to isolate the magnetic ordering that emerged near absolute zero.

Rice researchers tune the color output of each array both by varying the length of the nanorods and by adjusting the length of the spaces between nanorods.

A chip, which contains nanoscale structures that enable electron cooling at room temperature, is pictured.

Ptychographic image using soft X-rays of lithium iron phosphate nanocrystal after partial dilithiation. The delithiated region is shown in red.

This view of the "belly" and part of the "head" of comet 67P/Churyumov-Gerasimenko indicates several morphologically different regions.

UB researchers have pinpointed important changes in cellular behavior that occur in Pemphigus Vulgaris, the rare, blistering skin disease shown in this microscopic image.

Graphene nanoribbons are fabricated by molecular assembly on a Cu(111) substrate. On this surface system, GNRs on grow in six azimuthal directions exclusively. White lines in the inset highlight the zigzag edges of a ribbon.

This new image from the VLT Survey Telescope at ESO’s Paranal Observatory in northern Chile shows a vast collection of stars, the globular cluster Messier 54. This cluster looks very similar to many others but it has a secret. Messier 54 doesn’t belong to the Milky Way, but is part of a small satellite galaxy, the Sagittarius Dwarf Galaxy. This unusual parentage has now allowed astronomers to use the Very Large Telescope (VLT) to test whether there are also unexpectedly low levels of the element lithium in stars outside the Milky Way.

Because gold nanorods are longer than they are wide, 3-D nanorod supercrystals have "anisotropic" properties, which means they have a different response to external fields in one direction than another.
