Fields of dreams? Electromagnetic fields and the links to cancer

Article Abstract:

Various scientific studies have postulated a link between cancer and electromagnetic fields (emfs), particularly in children, yet none of these studies has been conclusive. The most noteworthy, conducted by David Savitz of North Carolina University, demonstrated a correlation between emf proximity to power lines and cancer risk but was unable to establish a direct link between measured emfs and cancers. Studies of adults are even more complicated since researchers must deal with more variables, namely occupational risk and longer lifetimes.

Intelligent transportation

Article Abstract:

The use of intelligent vehicle-highway systems currently under development will lead to faster, safer, more efficient and more environmentally beneficial transportation. Collision avoidance, communication and guidance systems would fully automate the driving experience. Improved automation would also simplify public transportation. Similar projects are currently underway in Europe and Japan. It is estimated that these systems could reduce traffic congestion by as much as 20% by the year 2011.

Subsurface barrier trapped diverse contaminants, let water through

Article Abstract:

Researchers at the New Mexico Institute of Mining and Technology have developed a low-cost subsurface barrier which effectively traps a large number of organic and inorganic contaminants without hindering water flow. The new barrier is formed by treating zeolite with hexadecyltrimethylammonium, a cheap and commonly-used surfactant. Its developers claim that barriers made of treated zeolite would cost as low as $0.25 per lb.
