The air in Fallon, Nev. has significantly higher levels of tungsten and cobalt than does the air in neighboring towns, according to a new research report. The research suggests that the metals in the air come from a point source within Fallon, a community of about 8,000 located in Churchill County about 60 miles east of Reno, Nev.
The finding that Fallons air differs from nearby towns might have medical implications. Since 1997, 16 cases of childhood leukemia have been diagnosed in children who lived in the Fallon area for some time prior to diagnosis. In a 2003 U.S. Health and Human Services report investigating possible causes for the leukemia cases in Fallon, tungsten was mentioned as "a contaminant of concern because it was elevated in urine samples" collected from Fallon-area residents as part of the investigation.
The metal, a component of tungsten steel and tungsten carbide, is used in tools exposed to high temperatures, such as drill bits and the filaments of incandescent light bulbs. Tungsten is naturally present in soils and rocks in Churchill County and other parts of Nevada. The metal was mined in the region around Fallon at various sites, including Churchill Butte.

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...
