Nanostructures half the breadth of a DNA strand could improve the efficiency of light emitting diodes (LEDs), especially in the "green gap," a portion of the spectrum where LED efficiency plunges, simulations at the U.S. Department of Energy's National Energy Research Scientific Computing Center (NERSC) have shown.
A team of scientists led by astronomers at the University of California, Riverside has used NASA's Hubble Space Telescope to uncover the long-suspected underlying population of galaxies that produced the bulk of new stars during the universe's early years.
Astronomers using NASA's Spitzer Space Telescope have discovered what may be the nearest world to our solar system that's smaller than Earth.
Engineers from NASA and the US Department of Energy (DOE) are working on a suitcase-sized nuclear reactor for use on the moon and other planets.
No, it isn't just your imagination. The economic situation in our Democratic Republic has gone from bad to worse, as the chasm between the "haves" and "have-nots" continues to widen.
