Researchers create nanotubes that change colors, form 'nanocarpet' and kill bacteria
...m-temperature conditions, the significant costs of synthesizing carbon nanotubes can be reduced," explained Sang Beom Lee, Ph.D., research assistant professor of bioengineering in the School of Engineering, who is listed as first author. To test the nanostructure's potential as a biosensor and antimicrobial, the...22nd amino acid synthesized and added to genetic code of e. coli bacteria

...re useful because normally when a ribosome that is synthesizing a protein reaches a nonsense codon, the ribosome dissociates from the mRNA and synthesis stops. Hence, nonsense codons are also referred to as "stop" codons. One of these, the amber stop codon UAG, played an important role in Schultz's research.

...effective as the more finicky bone marrow cells at synthesizing new bone to bridge the defect. In contrast, cells derived from tissue that covers the brain showed no bone growth during the same time period. The new bone growth began next to the brain, suggesting those cells were sending out bone growth-promoting ...Institute for Systems Biology, Pacific Northwest National Laboratory announce collaboration

... graduate student working in his lab interested in synthesizing new molecules. "Actually, once you think of it, it's really a pretty simple substitution," says Pratt. Still, it took a year to work out a 12-step process that produced the most effective member of this new class of compounds in quantities large enou...Scientists at Scripps Research describe new strategy for the synthesis of glycoproteins
...D., the team of scientists discovered a new way of synthesizing glycoproteins, and they report their strategy in the latest issue of the journal Science. The strategy, which avoids some of the bottlenecks of previous methods, involves using a modified form of the bacterium Escherichia coli to express a glycos...Exxon Valdez oil spill impacts lasting far longer than expected, scientists say
