Physicists put new perspective on biochemical problem

January 13, 2012 3:31 am | News | Comments

Purdue University physicists created computational tools that can predict the fleeting structures of iron-containing enzymes as they transform during chemical reactions. Many of these temporary but critical structures have eluded capture through traditional experimental methods such as X-ray crystallography.

Fiber Optic Raman Probe

January 13, 2012 3:14 am | Product Releases | Comments

B&W Tek Inc. introduced the BAC200, a fiber optic Raman probe capable of delivering the performance of a larger Raman probe in a small diameter of less than 4 mm with enhanced optical collection power.

Metrology Software

January 13, 2012 3:10 am | Product Releases | Comments

Heidenhain announced the latest version of their PC-based QUADRA-CHEK Metrology software, providing advanced functionality for inspection measurement machines. This software makes it possible to perform 2D and 3D measuring tasks in the field of metrology when standard DRO products will not suffice.

Light from biggest map of the universe tells us about its matter

January 12, 2012 11:03 am | News | Comments

For more than a decade, the three Sloan Digital Sky Surveys have surveyed well over a quarter of the night sky and produced the biggest 3D color map of the universe ever. Now, the sheer volume of light information it contains has allowed researchers to make the most accurate calculation yet of how matter clumps together.

Tiny transmitter sets frequency record

January 12, 2012 10:55 am | by Christian Meier | News | Comments

A team in Germany has built a transmitter less than a millimeter square that has generated the highest frequency ever attained by a microelectronic device: 1.111 THz. Compared to previous transmitters that have been bulky and expensive, the new device could soon find use in engineering applications.

‘Bubblegram’ imaging reveals inner working of viruses

January 12, 2012 10:49 am | News | Comments

Despite cryo-electron microscopy’s ability to resolve viruses, scientists have been unable to clearly visualize structures inside of viruses because radiation is used to image them. Reserachers at the National Institutes of Health invented a new technique that turns this radiation into an imaging asset.

Pill may prevent Listeria infection

January 12, 2012 8:42 am | News | Comments

Modified probiotics, the beneficial bacteria touted for their role in digestive health, could one day decrease the risk of Listeria infection in people with susceptible immune systems, according to Purdue University research.

Graphene quantum dots: The next big small thing

January 12, 2012 8:29 am | News | Comments

A Rice University laboratory has found a way to turn common carbon fiber into graphene quantum dots. The sub-5-nm carbon-based quantum dots were produced in bulk through the wet chemical process, and are highly soluble. Their size can be controlled via the temperature at which they're created.

Study provides best look yet at a cell’s waste-disposal system

January 12, 2012 7:42 am | News | Comments

Using electron microscopy and a revolutionary new system for protein expression, researchers at Lawrence Berkeley National Laboratory have provided the most detailed look ever at the “regulatory particle” used by proteasomes to identify and degrade proteins marked for destruction.

Lab-made tissue picks up the slack of Petri dishes

January 12, 2012 5:56 am | News | Comments

New research demonstrates that previous models used to examine cancer may not be complex enough to accurately mimic the true cancer environment. Using oral cancer cells in a 3D model of lab-made tissue that mimics the lining of the oral cavity, the researchers found that the tissue surrounding cancer cells can epigenetically mediate, or temporarily trigger, the expression or suppression of a cell adhesion protein associated with the progression of cancer.

Lab method uses mass spectrometry to detect staph infections

January 12, 2012 5:25 am | News | Comments

Researchers from the Georgia Institute of Technology and the Centers for Disease Control and Prevention have developed a new laboratory test that can rapidly identify the bacterium responsible for staph infections. This new test takes advantage of unique isotopic labeling combined with specific bacteriophage amplification to rapidly identify Staphylococcus aureus .

Team models ionic conductivity in doped ceria for fuel cell electrolyte

January 12, 2012 3:55 am | News | Comments

Optimizing the conductivity of ceria-based oxides, or doped ceria, is crucial to their use as electrolytes in future solid oxide fuel cells. Researchers from NIST and Arizona State University have successfully used kinetic lattice Monte Carlo simulations to predict the optimum dopant concentration for maximizing conductivity for gadolinium doped ceria at temperatures that are practical for fuel cell operation.
