NASA Launches Mission to Study Moon From Crust to Core (September 10, 2011) -- NASA's twin lunar Gravity Recovery and Interior Laboratory (GRAIL) spacecraft lifted off from Cape Canaveral Air Force Station in Florida at 9:08 a.m. EDT (6:08 a.m. PDT) Saturday, Sept. 10, to study the moon in unprecedented detail. GRAIL-A is scheduled to reach the moon on New Year's Eve 2011, while GRAIL-B will arrive New Year's Day 2012. The two solar-powered spacecraft will fly in tandem orbits around the moon to measure its gravity field. GRAIL will answer longstanding questions about the moon and give scientists a better understanding of how Earth and other rocky planets in the solar system formed. ... > full story
Nanoscale spin waves can replace microwaves (September 10, 2011) -- Scientists have now demonstrated that theories about nanoscale spin waves agree with observations. This opens the way to replacing microwave technology in many applications, such as mobile phones and wireless networks, by components that are much smaller, cheaper, and that require less resources. ... > full story
Fermi's latest gamma-ray census highlights cosmic mysteries (September 10, 2011) -- Every three hours, NASA's Fermi Gamma-ray Space Telescope scans the entire sky and deepens its portrait of the high-energy universe. Every year, the satellite's scientists reanalyze all of the data it has collected, exploiting updated analysis methods to tease out new sources. These relatively steady sources are in addition to the numerous transient events Fermi detects, such as gamma-ray bursts in the distant universe and flares from the sun. Earlier this year, the Fermi team released its second catalog of sources detected by the satellite's Large Area Telescope, producing an inventory of 1,873 objects shining with the highest-energy form of light. ... > full story
Milestones for two radiation machines used to test U.S. defenses against atomic weapons (September 9, 2011) -- Two remarkable pulsed-power machines used to test the nation's defenses against atomic weapons have surpassed milestones at Sandia National Laboratories: 4,000 firings, called "shots," on the Saturn accelerator and 9,000 shots on the HERMES III accelerator. Saturn -- originally projected to last 5 to 10 years -- began operating in 1987. Its major function has been to produce X-rays to test the effectiveness of countermeasures used to protect electronics and other materials against X-ray radiation from nuclear weapons. ... > full story
What's in a name? Names, not social networks, bind us to global cultural and ethnic communities (September 9, 2011) -- Links between hundreds of millions of names belonging to people around the world have been analyzed by geographers in the UK and New Zealand. The results reveal how our forenames and surnames are connected in distinct global networks of cultural, ethnic and linguistic communities. The researchers' methods could be of use to social scientists and health researchers investigating migration, identity and integration. ... > full story
Designing high-rise buildings: World still learning lessons of 9/11 (September 9, 2011) -- A university professor who carried out a major study into the evacuation of the World Trade Centre after 9/11 says the "far-reaching impact" of the attacks is still being felt when it comes to the design of new high-rise buildings across the world. ... > full story
Where does all Earth's gold come from? Precious metals the result of meteorite bombardment, rock analysis finds (September 9, 2011) -- Ultra high precision analyses of some of the oldest rock samples on Earth provides clear evidence that the planet's accessible reserves of precious metals are the result of a bombardment of meteorites more than 200 million years after Earth was formed. ... > full story
New cooling system raises efficiency of oil and gas processing (September 9, 2011) -- Mathematicians in Norway have devised a solution for making sub-sea oil and gas processing more efficient at substantially lower cost. Using their expertise in fluid mechanics they have developed a unique design for a subsea cooling system. Their research can help to recover more oil and gas resources both in the North Sea and elsewhere. The first newly constructed processing facilities could be installed on the seabed as early as 2013. The equipment will be designed to last 30 years, which means that in addition to being smaller and lighter, it has to be durable, maintenance-free and without moving parts. ... > full story
Powered by seaweed: Polymer from algae may improve battery performance (September 9, 2011) -- By looking to Mother Nature for solutions, researchers have identified a promising new binder material for lithium-ion battery electrodes that could not only boost energy storage, but also eliminate the use of toxic compounds now used in manufacturing the components. Known as alginate, the material is extracted from common, fast-growing brown algae. ... > full story
New method to grow synthetic collagen unveiled: New material may find use in reconstructive surgery, cosmetics, tissue engineering (September 9, 2011) -- In a significant advance for cosmetic and reconstructive medicine, scientists have unveiled a new method for making synthetic collagen. The new material, which forms from a liquid in as little as an hour, has many of the properties of natural collagen and may prove useful as a scaffold for regenerating new tissues and organs from stem cells. ... > full story
Managing intellectual property a challenge for firms, innovators (September 9, 2011) -- The increasing complexity of multi-invention technologies such as laptops and smartphones raises serious challenges for firms looking to cash in with the "next big thing," and points to a need for businesses to integrate their patent and business strategies, according to a patent strategy expert. ... > full story
Cotton's potential for padding nonwovens (September 9, 2011) -- Scientists have conducted studies to investigate the use of virgin cotton in nonwoven materials and products. ... > full story
