CHAMPAIGN, lll. — Researchers (and some cat-owners) wanted to know: What do feral and free-roaming house cats do when they're out of sight? A two-year study offers a first look at the daily lives of these feline paupers and princes, whose territories overlap on the urban, suburban, rural and agricultural edges of many towns.

CAMBRIDGE, Mass. -- A team of researchers at MIT has found a way to make complex composite materials whose attributes can be fine-tuned to give various desirable combinations of properties such as stiffness, strength, resistance to impacts and energy dissipation.
A new biomaterial designed for repairing damaged human tissue doesn't wrinkle up when it is stretched. The invention from nanoengineers at the University of California, San Diego marks a significant breakthrough in tissue engineering because it more closely mimics the properties of native human tissue.
Smarter product designs, support for developing country waste management schemes, and encouraging developed country households not to 'squirrel away' old electronic goods in drawers and closets could help boost recycling of metals world-wide.
According to a report released today by the United Nations Environment Programme (UNEP), recycling rates of metals are in many cases far lower than their potential for re-use.
AURORA, Colo. (May 25, 2011) – Researchers studying driving habits and accident rates among the elderly found a majority surveyed supported mandatory retesting of drivers based on age while saying they would hand over the keys if a doctor or loved one said they were no longer fit to drive.
SEATTLE–The Pacific Northwest has the diverse feedstocks, fuel-delivery infrastructure and political will needed to create a viable biofuels industry capable of reducing greenhouse gases and meeting the future fuel demands of the aviation industry. Creating an aviation biofuels industry, however, will depend upon securing early government policy support to prioritize the aviation industry in U.S. biofuel development.
Researchers from North Carolina State University have developed two new techniques to help maximize the performance of multi-core computer chips by allowing them to retrieve data more efficiently, which boosts chip performance by 10 to 40 percent.
To do this, the new techniques allow multi-core chips to deal with two things more efficiently: allocating bandwidth and "prefetching" data.
A recent study* at the National Institute of Standards and Technology (NIST) may have revealed the optimal characteristics for a new type of computer memory now under development. The work, performed in collaboration with researchers from George Mason University (GMU), aims to optimize nanowire-based charge-trapping memory devices, potentially illuminating the path to creating portable computers and cell phones that can operate for days between charging sessions.
RESEARCH TRIANGLE PARK, N.C. - May 25, 2011 - Semiconductor ResearchCorporation (SRC), the world's leading university-research consortiumfor semiconductors and related technologies, and researchers from theUCLA Henry Samueli School of Engineering and Applied Science havedeveloped a new method of design-dependent process monitoring forsemiconductor wafer manufacturing.
In the first study of its kind on K-12 Christian education in North America, University of Notre Dame sociologist David Sikkink, in partnership with Cardus – a public policy think tank – found that while Protestant Christian school graduates show uncommon commitment to their families and churches, donate more money than graduates of other schools, and divorce less, they also have lower incomes, less education, and are less engaged in politics than their Catholic and non-religious private school peers.
For the first time, results on the impact of gaming devices on finger and wrist pain in children were presented today at the EULAR 2011 Annual Congress. Data comparing two schools in the USA demonstrate that young children experience high levels of pain following long term use of gaming devices and mobile phones indicating that excessive gaming may negatively impact on joint health.
Establishing an economically and environmentally beneficial, 'bio-derived' Australian and New Zealand aviation fuels industry is a viable proposition, according to a report compiled by CSIRO in collaboration with the region's major aviation industry players.The report, Flight Path to Sustainable Aviation, predicts that over the next 20 years a new, sustainable, Australia-New Zealand aviation fuels industry could cut greenhouse gas emissions by 17 per cent, generate more than 12,000 jobs and reduce Australia's reliance on aviation fuel imports by $2 billion per annum.
Cell phone distractions account for more than 300,000 car crashes each year. As a result, most states have put laws in place to limit or prohibit the use of things like cell phones and PDAs while driving. But a new study led by Temple University finds a widening gap between the evidence on distracted driving and the laws being passed to address the problem.
