Galaxy caught blowing bubbles (October 1, 2011) -- Hubble's famous images of galaxies typically show elegant spirals or soft-edged ellipses. But these neat forms are only representative of large galaxies. Smaller galaxies like the dwarf irregular galaxy Holmberg II come in many shapes and types that are harder to classify. This galaxy's indistinct shape is punctuated by huge glowing bubbles of gas. ... > full story
Pressurized vascular systems for self-healing materials (October 1, 2011) -- Artificial microvascular systems for self-repair of materials damage, such as cracks in a coating applied to a building or bridge, have relied on capillary force for transport of the healing agents. Now, researchers have demonstrated that an active pumping capability for pressurized delivery of liquid healing agents in microvascular systems significantly improves the degree of healing compared with capillary force methods. ... > full story
Hydrogen released to fuel cell more quickly when stored in metal nanoparticles (October 1, 2011) -- Researchers have demonstrated that the size of a metal alloy nanoparticle influences the speed with which hydrogen gas is released when stored in a metal hydride. The smaller the size of the nanoparticle, the greater the speed at which the hydrogen gas makes its way to the fuel cell. ... > full story
Space telescopes reveal secrets of turbulent black hole (September 30, 2011) -- Supermassive black holes at the hearts of active galaxies swallow large amounts of gas. During this feast they spill a lot of their 'food', which is discharged in turbulent outbursts. An international team of astronomers has revealed some striking features of such an outburst around a supermassive black hole in a distant galaxy. They found a very hot 'convertor' corona hovering above the black hole and cold gas 'bullets' in hotter diffuse gas, speeding outwards with velocities up to 700 km/s. ... > full story
Researchers realize high-power, narrowband terahertz source at room temperature (September 30, 2011) -- Researchers have developed a simpler way to generate single-chip terahertz radiation, a discovery that could soon allow for more rapid security screening, border protection, high sensitivity biological/chemical analysis, agricultural inspection, and astronomical applications. ... > full story
Building better catalysts (September 30, 2011) -- Chemists have developed a method to design and test new catalysts, which are substances that speed chemical reactions and are crucial for producing energy, chemicals and industrial products. By using the new method, the chemists also made a discovery that will make it easier to design future catalysts. ... > full story
Engineers 'cook' promising new heat-harvesting nanomaterials in microwave oven (September 30, 2011) -- Waste heat is a byproduct of nearly all electrical devices and industrial processes, from driving a car to flying an aircraft or operating a power plant. Engineering researchers have developed new nanomaterials that could lead to techniques for better capturing and putting this waste heat to work. The key ingredients for making marble-sized pellets of the new material are aluminum and a common, everyday microwave oven. ... > full story
Closing of a collider . . . and opening of a new frontier: Fermilab moves toward new discoveries (September 30, 2011) -- Today, Fermi National Accelerator Laboratory (Fermilab) will shut down its Tevatron particle accelerator after nearly 30 years in operation. Named one of the top engineering achievements of the past 100 years, the Tevatron accelerated particles to almost the speed of light along its 4-mile ring, smashed them together, and studied the resulting particle showers in order to understand fundamental facts about elementary particles and forces. ... > full story
Scientists release most accurate simulation of the universe to date (September 30, 2011) -- The Bolshoi supercomputer simulation, the most accurate and detailed large cosmological simulation run to date, gives physicists and astronomers a powerful new tool for understanding such cosmic mysteries as galaxy formation, dark matter, and dark energy. ... > full story
Scientists and engineers create the 'perfect plastic' (September 30, 2011) -- Researchers have solved a long-standing problem that could revolutionize the way new plastics are developed. ... > full story
Technique to control light from nanoparticles (September 30, 2011) -- Chemists have discovered a way to use liquid crystals to control light scattered from gold nanorods. The researchers use voltage to sensitively manipulate the alignment of liquid crystal molecules that alternately block and reveal light from the particles; the gold nanorods collect and retransmit light in a specific direction. ... > full story
Researchers produce cheap sugars for sustainable biofuel production (September 30, 2011) -- Researchers have developed technologies to efficiently produce, recover and separate sugars from the fast pyrolysis of biomass. That's a big deal because those sugars can be further processed into biofuels. ... > full story
