Ships of the future may be able to move through the water without a creating a wake. That is according to a pair of physicists in the US, who have proposed a new type of material that lets water flow around an object as if it were not there at all. The design, which has […]
Movement of Black Holes Powers Quasars, the Universe’s Brightest Lights
July 21, 2011
Whether on their own or orbiting as a pair, black holes don’t typically sit still. Not only do they spin, they can also move laterally across their host galaxy. And according to astrophysicists at Brigham Young University, both types of movement power massive jets of energy known as quasars. The study, which appears in the […]

Sugar Molecule in Milky Way’s Habitable Zone Hints at Possibility of Life
July 21, 2011
Scientists recently detected an organic sugar molecule that is directly linked to the origin of life, in a region of our galaxy where habitable planets could exist. Glycolaldehyde, (HOCH 2 -CH = O) the simplest of the monosaccharide sugars, can react with the substance propenal to form ribose, a central constituent of Ribonucleic acid (RNA), thought to be […]
