X-rays yield pictures and chemical clues that may help trace contaminants, thwart terrorists
As part of the search for better ways to track and clean up soil contaminants, scientists at the U.S. Department of Energys Brookhaven National Laboratory and Stony Brook University have developed a new way to "image" the internal chemistry of bacteria. The technique will allow scientists to "see" at the molecular level how soil-dwelling microbes interact with various pollutants. The method might also help scientists better understand and prevent bacterial diseases, or find ways to detect or disable bacteria used in a terror attack.
"The more we learn about soil microbe chemistry, the better well be able to predict the movement of contaminants in the environment," said Brookhaven microbiologist Jeffrey Gillow. "What we learn might also suggest new ways to harness microorganisms to immobilize things like heavy metals and radioactive contaminants," he said. Gillow will give a talk on the new method at the 230th national meeting of the American Chemical Society in Washington, D.C. on Monday, August 29, 2005 at 11:10 a.m. in room 204C of the Washington Convention Center.

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.
Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...
The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.
Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
