Spiral Beauty Graced by Fading Supernova

About 35 million light-years from Earth, in the constellation of Eridanus (The River), lies the spiral galaxy NGC 1637. Back in 1999 the serene appearance of this galaxy was shattered by the appearance of a very bright supernova. Astronomers studying the aftermath of this explosion with ESO’s Very Large Telescope at the Paranal Observatory in Chile have provided us with a stunning view of this relatively nearby galaxy.

Discovery of first motor with revolution motion in a virus-killing bacteria advances nanotechnology

Scientists have cracked a 35-year-old mystery about the workings of the natural motors that are serving as models for development of a futuristic genre of synthetic nanomotors that pump therapeutic DNA, RNA or drugs into individual diseased cells. Their report revealing the innermost mechanisms of these nanomotors in a bacteria-killing virus — and a new way to move DNA through cells

Thin films of nickel and iron oxides yield efficient solar water-splitting catalyst: Basic University of Oregon research shows promise in efforts to get hydrogen fuel from sunlight and water

University of Oregon chemists say that ultra-thin films of nickel and iron oxides made through a solution synthesis process are promising catalysts to combine with semiconductors to make devices that capture sunlight and convert water into hydrogen and oxygen gases.

NIST Mechanical Micro-Drum Used as Quantum Memory

One of the oldest forms of computer memory is back again—but in a 21st century microscopic device designed by physicists at the National Institute of Standards and Technology (NIST) for possible use in a quantum computer.

Smallest Vibration Sensor in the Quantum World

Carbon nanotubes and magnetic molecules are considered building blocks of future nanoelectronic systems. Their electric and mechanical properties play an important role. Researchers of Karlsruhe Institute of Technology and French colleagues from Grenoble and Strasbourg have now found a way to combine both components on the atomic level and to build a quantum mechanical system with novel properties.
