Expert says the government must do more to eliminate lead from the environment
Exposure to lead may be one of the most significant causes of violent crime in young people, according to one of the nation’s leading researchers on the subject. "When environmental lead finds its way into the developing brain, it disturbs neural mechanisms responsible for regulation of impulse. That can lead to antisocial and criminal behavior," reported Herbert L. Needleman, M.D., professor of psychiatry and pediatrics at the University of Pittsburgh School of Medicine, at the 2005 American Association for the Advancement of Science (AAAS) Annual Meeting. "The government needs to do more to eliminate sources of lead in the environment."
According to the U.S. Environmental Protection Agency, humans can encounter lead through deteriorating paint and dust, air, drinking water, food and contaminated soil. Sources of lead are plentiful – until the 1970s lead was used in paint, gasoline and older water pipes. Today, much of that lead is still out there – on old window frames, in the soil of the vegetable gardens and in the drinking water of many American cities.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
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...
