Printable batteries

Friday, July 03, 2009 00:00 MST

For a long time, batteries were bulky and heavy. Now, a new cutting-edge battery is revolutionizing the field. It is thinner than a millimeter, lighter than a gram, and can be produced cost-effectively through a printing process.

Waste water treatment plant mud used as 'green' fuel

Monday, June 29, 2009 00:00 MST

Catalan scientists have shown that using mud from waste water treatment plants as a partial alternative fuel can enable cement factories to reduce their CO2 emissions and comply with the Kyoto Protocol, as well as posing no risk to human health and being profitable. These are the results of an environmental impact assessment.

Scientists cage chemical demon

A Cambridge University-led research team has discovered a technique to safely handle and transport white phosphorous.

Structural biology scores with protein snapshot

Saturday, June 27, 2009 00:00 MST

In a landmark technical achievement, investigators in the Vanderbilt Center for Structural Biology have used nuclear magnetic resonance methods to determine the structure of the largest membrane-spanning protein to date.The group's ability to determine the NMR structure of the bacterial protein diacylglycerol kinase, reported in the June 26 issue of Science, suggests that similar methods can now be used to study the structures of other membrane proteins.

Cells use import machinery to export their goods as well

Friday, June 26, 2009 00:00 MST

Research suggests a new level of regulation for cellular export process by molecules previously assumed to be dedicated to import activities.

Feather fibers fluff up hydrogen storage capacity

Thursday, June 25, 2009 00:00 MST

Scientists in Delaware say they have developed a new hydrogen storage method -- carbonized chicken feather fibers -- that can hold vast amounts of hydrogen, a promising but difficult to corral fuel source, and do it at a far lower cost than other hydrogen storage systems under consideration.

A Canada-wide technology platform for mapping the human interactome

Wednesday, June 24, 2009 00:00 MST

The Canada Foundation for Innovation announced the award of $9.16 million for the creation of a national technology platform aimed at mapping the human interactome. This national platform, headed by Dr. Benoit Coulombe, will not only provide Canadian researchers with new state-of-the-art equipment in proteomics, functional genomics and bioinformatics, but also bring together integrated infrastructure for deciphering the human interactome an expertise that, until now, has been spread in 12 universities across Canada.

Researchers observe single protein dimers wavering between two symmetrically opposed structures

Tuesday, June 23, 2009 00:00 MST

Researchers at the Scripps Research Institute, the University of California, San Diego, and Ohio State University have used a very sensitive fluorescence technique to find that a bacterial protein thought to exist in one "natural" three-dimensional structure (shape), can actually twist itself into a second form, depending on the protein's chemical environment. One folded form is active and the other is inactive, but the protein can easily morph from one state to another.

Important symbol of pollution is broken down by microbes

Monday, June 22, 2009 00:00 MST

Immobilized microbes can break down potentially harmful phthalates, according to researchers in China, writing in the International Journal of Environment and Pollution. The microbes might be used to treat industrial waste water and so prevent these materials from entering the environment.
