Even in new designs, it's not a bad idea to see how old Mother Nature does it. Using that principle, a group of researchers at the U.S. Department of Energy’s Ames Laboratory is mimicking bacteria to…

Electronics work better under cold conditions (-150 C). With less thermal noise, detectors are more sensitive and speed and reliability are increased. Low-noise amplifiers reduce noise further.…

Green is in. Even the army is making sure to use environmentally friendly paint on its bombers and environmentally conscious people who have made great efforts to put ethical bullets into mainstream…

Heavy water is water (H2O) in which oxygen is bound to atoms of the hydrogen isotope deuterium (2H). Heavy water is so named because it is significantly more dense (>1.1 g/cm3) than ordinary ("…

DNA, the stuff our genes are made of, is the building material of choice for nanoscale objects. A team led by Günter von Kiedrowski at the Ruhr University in Bochum has now made a dodecahedron (a…

The "Large Molecule Heimat" is a very dense, hot gas clump within the star forming region Sagittarius B2. In this source of only 0,3 light-year diameter, which is heated by a deeply embedded newly…

Scientists have reconstructed changes in Earth’s ancient ocean chemistry from about 2.5 to 0.5 billion years ago and say that a deficiency of oxygen and the heavy metal molybdenum in the ancient deep…

It may be only St. Patrick's Day but it's never too early to think about July 4th fireworks. Plus, 'green' has two meanings today. Most kids love fireworks. They make pretty colors and loud noises…

Fifty years have passed since the United States Department of Agriculture and the U.S. Army invented DEET to protect soldiers from disease-transmitting insects and in the process made civilian life…

An international team has achieved, by means of a controlled chemical process, that atoms of gold, silver and copper - intrinsically non-magnetic (not attracted to a magnet) - become magnetic.…
