TUCSON, Ariz. (Nov. 10, 2010) -- A unique underground surveillance system tested by UA researchers could be used to watch the entire U.S.-Mexico border continuously.
Early years initiatives for pre-school children are not delivering improvements in language and numeracy development, according to leading education experts.
Experts, conducting one of the largest surveys to date of the development of 117,000 children starting primary school in England over eight years, found that despite a raft of early years' initiatives, such as 'Sure Start', basic levels of development in early reading, vocabulary and maths have remained largely unchanged.
GREENBELT, Md. -- The size, background ecology, and development patterns of major northeastern cities combine to make them unusually warm, according to NASA scientists who presented new research today at an American Geophysical Union meeting, in San Francisco, Calif.
Researchers from the Peninsula Technology Assessment Group (PenTAG) at the Peninsula College of Medicine and Dentistry have contributed to new National Institute for Health and Clinical Excellence (NICE) guidance on preventing unintentional injury to the under-15s.
Simulations performed at Southwest Research Institute may explain how Saturn's majestic rings and icy inner moons formed following the collision of a Titan-sized satellite with the planet, according to a paper published in Nature magazine's Dec. 12 Advance Online Publication.
For centuries, people wondered how the leopard got its spots. The consensus is pretty solid that evolution played a major role.
December 13, 2010 – The human body is home to a complex ecosystem of microbes increasingly recognized as having a critical role in both health and disease. Viruses can attack and change the composition of bacterial communities, yet little is known about how this might influence human health.

The small crater embedded in the northwestern rim of the Schiaparelli impact basin features prominently in this new image from ESA's Mars Express. All around is evidence for past water and the great martian winds that periodically blow.
Spearheaded by the University of Manchester's Jodrell Bank Observatory and funded by the Science and Technology Facilities Council, the e-MERLIN telescope will allow astronomers to address key questions relating to the origin and evolution of galaxies, stars and planets.
To demonstrate its capabilities, University of Manchester astronomers turned the new telescope array toward the "Double Quasar". This enigmatic object, first discovered by Jodrell Bank, is a famous example of Einstein's theory of gravity in action.
What algorithms should an air defense system work with? Particle swarm algorithms if there are ten targets to be hit. If there are more than ten targets, greedy algorithms work best. These findings are presented by researcher Fredrik Johansson at the Informatics Research Centre, University of Skövde, in Sweden.
So-called TEWA systems (Threat Evaluation & Weapon Allocation) are used to protect strategic targets from enemy attacks, such as an airfield that needs to be protected from incoming missiles.
A peculiar gas-giant planet orbiting a sun-like star 1200 light-years away is the first carbon-rich world ever observed.
The implications are big for planetary chemistry, because without much oxygen, common rocks throughout the planet would be made of pure carbon, in forms such as diamonds or graphite.
