Disposable Sensor Uses DNA to Detect Hazardous Uranium Ions
Researchers at the University of Illinois at Urbana-Champaign have developed a simple, disposable sensor for detecting hazardous uranium ions, with sensitivity that rivals the performance of much more sophisticated laboratory instruments.
The sensor provides a fast, on-site test for assessing uranium contamination in the environment, and the effectiveness of remediation strategies, said Yi Lu, a chemistry professor at Illinois and senior author of a paper accepted for publication in the Proceedings of the National Academy of Sciences, and posted on its Web site. continue

Laboratory Drawer Refrigerator Provides Excellent Storage
Marvel Scientific’s new 6CRD Two-Drawer Refrigerator allows easy
access even from a seated position. Two deep, full-extension drawers
provide ample storage and superior visibility and access – no more
reaching to the back of a crowded shelf. Features include Commercial
UL Listing, eletronic touchpad controls with LED digital display,
auto defrost and heavy duty drawer slides to handle full loads.

Researchers Create Tiny Devices That Can Propel Themselves in Liquid, Perform Other Functions
North Carolina State University scientists have figured out a method to supply microscopic devices with enough energy to not only allow them to propel themselves through liquid – a difficult function in its own right – but also to perform some other functions, like emitting light.
The findings have the potential to lead to “smart devices” or “microrobots” that can interact with their environment and perform certain tasks – like moving, sensing other materials, including biological materials, lighting up and spinning – on their own.
The millimeter-sized devices can be controlled externally and have the potential to be powered by radio waves. continue

Moore Funds Center to Facilitate Chemical Discovery
Facilities to automate the work of experimental chemistry may soon accelerate the process of chemical discovery at the California Institute of Technology, thanks to a grant of over $11 million from the Gordon and Betty Moore Foundation.
The grant will establish a Center for Catalysis and Chemical Synthesis (3CS), with facilities operated by the Division of Chemistry and Chemical Engineering. The center aims to speed the invention of new catalytic reactions, much as improved robotics accelerated the Human Genome Project.
"The increasing demands on chemistry resulting from new drug targets from the Human Genome Project and critical environmental requirements of chemical processes require us to develop more efficient techniques for chemical discovery," Grubbs says. continue

Free-Science Movement Gains a Foothold at Berkeley
When the journal Nature reported last month that a group of scientific-publishing goliaths had enlisted a "PR pit bull" to "take on the free-information movement" — a story that quickly entered the mainstream media through the Washington Post, then replicated itself endlessly via the blogosphere — the move was widely viewed as a declaration of war. The long knives, it appeared, were finally out. In response, the slingshots, too, came out in force. continue
