Turn out the light!
A collaborative team of researchers has discovered what turns the lights out from space. Using sophisticated features on a transmission electron microscope, John P. Bradley, Ph.D., Director of the Institute for Geophysics and Planetary Physics at Lawrence Livermore National Laboratory, has discovered that organic carbon and amorphous silicates in interstellar grains embedded within interplanetary dust particles (IDPs) are the carriers of the astronomical 2175 Å extinction line.
Discovered by astronomers more than 40 years ago, the astronomical extinction line occurs at a wavelength of 2175 Angstroms, blocking light from stars from reaching the Earth due to the absorption of light by dust in the interstellar medium. One Angstrom (Å ) is one one-hundred millionth of a centimeter.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
