The U.S. Environmental Protection Agencys scientific and technical decisions in assessing risks to human health from pollution at a Superfund site in the Coeur dAlene River Basin have been generally sound, says a new report from the National Academies National Research Council. And the agencys remediation plans for residential areas should adequately protect residents against the most serious health threats, provided floods do not recontaminate cleaned-up areas. However, the committee that wrote the report expressed "substantial concerns" about EPAs proposed strategies for cleaning up and protecting the environment, including fish and wildlife.
Congress asked the Research Council to assess EPAs decisions concerning a 1,500-square-mile area in the Coeur dAlene River Basin of northern Idaho and eastern Washington that is designated for cleanup under Superfund legislation because of contamination from years of mining for silver, zinc, and lead. A 21-square-mile "box" around Idahos Bunker Hill Mining and Metallurgical Complex was declared a Superfund site in 1983 after high blood levels of lead were detected in local children, and high levels of metals were measured in the environment.
EPA expanded its Superfund cleanup in 1998 to include contaminated areas throughout the Coeur dAlene River Basin, and in 2002 outlined a plan to clean up parts of this pollution and lessen risks to human health and the environment. Three-quarters of the proposed $359 million expenditures are to finance the first steps toward protecting the environment, including fish and wildlife, over an approximate 30-year period. The committees concerns pertain primarily to these remedies. The other quarter of the funds is intended to address human health risks, which EPA expects to accomplish well before the 30-year mark.

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
Transistors based on carbon nanostructures: what sounds like a futuristic dream could be reality in just a few years' time. An international research team working with Empa has now succeeded in producing nanotransistors from graphene ribbons that are only a few atoms wide, as reported in the current issue of the trade journal "Nature Communications."
Graphene ribbons that are only a few atoms wide, so-called graphene nanoribbons, have special electrical properties that make them promising candidates for the...
