In this image from NASA's Curiosity Mars rover looking up the ramp at the northeastern end of "Hidden Valley," a pale outcrop including drilling target "Bonanza King" is at the center of the scene.

Image of 67P/Churyumov-Gerasimenko shows the diversity of surface structures on the comet's nucleus.

While the economy of the United States stands at the verge of collapse, hobbling along under the dead weight of the London-Wall Street money system, China is on a trajectory upward, propelled by its orientation toward an "American System"-style, science-driver economic policy, and a defense of national sovereignty. China's dedication to the future development of mankind is exemplified by its commitment to elevate and upgrade its space program, to a mission of exploring, developing, and mining the Moon, with a special emphasis placed upon the ultimate use of the chemical isotope helium-3, which is found in relative abundance in the Moon's regolith (lunar soil), as a fuel for thermonuclear fusion-powered energy production—the next frontier in technology revolutions.

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.
