Birth of famous black hole: Longstanding mysteries about object called Cygnus X-1 unraveled (November 18, 2011) -- A precise distance measurement by the Very Long Baseline Array (VLBA) allowed astronomers to accurately calculate the mass and spin of a famous black hole, thus providing a complete description of the object. ... > full story

World's most difficult chemical experiment: The struggle to discover the secret of super-heavy elements (November 18, 2011) -- In order to find the chemical properties of super-heavy elements, chemists must conduct one of the world's most demanding chemical experiments in a matter of seconds. ... > full story

Nanoparticles used as additives in diesel fuels can travel from lungs to liver (November 18, 2011) -- Recent studies have demonstrated that nanoparticles of cerium oxide -- common diesel fuel additives used to increase the fuel efficiency of automobile engines -- can travel from the lungs to the liver and that this process is associated with liver damage. ... > full story

New 'smart' material could help tap medical potential of tissue-penetrating light (November 18, 2011) -- Scientists are reporting development and successful initial testing of the first practical "smart" material that may supply the missing link in efforts to use in medicine a form of light that can penetrate four inches into the human body. The new polymer or plastic-like material has potential for use in diagnosing diseases and engineer new human tissues in the lab. ... > full story

Microfabrication breakthrough could set piezoelectric material applications in motion (November 18, 2011) -- Integrating a complex, single-crystal material with "giant" piezoelectric properties onto silicon, engineers and physicists can fabricate low-voltage, near-nanoscale electromechanical devices that could lead to improvements in high-resolution 3-D imaging, signal processing, communications, energy harvesting, sensing, and actuators for nanopositioning devices, among others. ... > full story

Chemists develop compounds capable of forming heath-resistant, economic and biocompatible gels (November 17, 2011) -- Eating a yogurt or a jelly, using a pharmaceutical or cosmetic cream or shampoo are just some of the numerous everyday actions in which we use gels developed through a process of gelation. Researchers have now developed a new family of compounds that enables to develop gels more resistant to high temperatures with a higher level of biocompatibility and able to work with a variety of organic solvents, and all this with an easy synthesis, scalable and low cost. This family of compounds has significant applications in industries such as pharmaceuticals and cosmetics or food industry, among others. ... > full story

French digitial kitchen is a recipe for success (November 17, 2011) -- An innovative kitchen that gives step-by-step cooking instructions in French could spark a revolution in language learning in the UK. ... > full story

Galaxies are the ultimate recyclers, NASA's Hubble confirms (November 17, 2011) -- New observations by NASA's Hubble Space Telescope are expanding astronomers' understanding of the ways in which galaxies continuously recycle immense volumes of hydrogen gas and heavy elements. This process allows galaxies to build successive generations of stars stretching over billions of years. ... > full story

Research cracks puzzle of enzyme critical to food supply (November 17, 2011) -- Researchers used the Stanford Synchrotron Radiation Lightsource at SLAC National Accelerator Laboratory to identify a key atom inside the part of the nitrogenase enzyme where atmospheric nitrogen is converted into a form that living things can use. ... > full story

Unusual liquid crystal structures on water surface (November 17, 2011) -- Some liquid crystals form monolayers on water surface. When compressed from sides, such films of monomolecular thickness can wrinkle like fabric on a flat, smooth table, pulled together with palms simultaneously from both sides. With increasing surface pressure, the wrinkles of the monolayer fold up and form subsequent layers. New mechanisms of multilayer formation are responsible for creation of liquid crystal films with a structure that has never been observed before. ... > full story

Brain study reveals how successful students overcome math anxiety (November 17, 2011) -- Using brain-imaging technology for the first time with people experiencing mathematics anxiety, scientists have gained new insights into how some students are able to overcome their fears and succeed in math. For the highly math anxious, researchers found a strong link between math success and activity in a network of brain areas in the frontal and parietal lobes involved in controlling attention and regulating negative emotional reactions. ... > full story

World's lightest material is a metal 100 times lighter than styrofoam (November 17, 2011) -- Engineers have developed the world's lightest material -- with a density of 0.9 mg/cc -- about 100 times lighter than Styrofoam. ... > full story
