Nanotube formation: researchers learn to control the dimensions of metal oxide nanotubes
08-23-2007 · EurekAlert!
Moving beyond carbon nanotubes, researchers are developing insights into a remarkable class of tubular nanomaterials that can be produced in water with a high degree of control over their diameter and length. Based on metal oxides in combination with silicon and germanium, such single-walled inorganic nanotubes could be useful in a range of nanotechnology applications that require precise control over nanotube dimensions.

Baby booms and birth control in space
09-25-2007 · EurekAlert!
Stars in galaxies are a bit similar to people: during the first phase of their existence they grow rapidly, after which a stellar birth control occurs in most galaxies. Thanks to new observations from Dutch astronomer Mariska Kriek with the Gemini Telescope on Hawaii and the Very Large Telescope in Chile, it is now known that a part of the heavy galaxies already stopped forming stars when the universe was still a toddler, about three billion years old.

Study finds oysters can take heat and heavy metals, but not both
12-13-2006 · EurekAlert!
Could low-level heavy metal pollution be combining with warm water temperatures to fatally weaken sea life? A study examining the joint effects of cadmium and temperature on mitochondrial metabolism in oysters finds a combined effect that is potentially lethal and could be a significant contributor to recent oyster declines. The research has broad implications for cold-blooded marine organisms.

In nature, proteins sweep up nanoparticles
06-14-2007 · EurekAlert!
Here's a pollution-control tip from nature: Deep inside a flooded mine in Wisconsin, scientists from several institutions including the US Department of Energy's Lawrence Berkeley National Laboratory have discovered a world in which bacteria emit proteins that sweep up metal nanoparticles into immobile clumps. Their finding may lead to innovative ways to remediate subsurface metal toxins.

Rising Ocean Temperatures, Pollution Have Oysters In Hot Water
10-13-2006 · ScienceDaily
Oysters exposed to high water temperatures and a common heavy metal are unable to obtain sufficient oxygen and convert it to cellular energy, according to a new study presented at the American Physiological Society conference, "Comparative Physiology 2006." The study showed how cadmium reduces the oyster's tolerance of warmer water temperatures and makes it more vulnerable during the summer when water temperatures rise.
