Proteomics brings researchers closer to understanding microbes that produce acid mine drainage

...nd how we might be able to use this information to better understand microbial systems in real-world conditions." Bacteria, along with ancient microbes called Archaea, in the biofilm capture carbon and nitrogen from the atmosphere and derive energy from iron that has been leached out of the iron sulfide ro...

Using nanoparticles, in vivo gene therapy activates brain stem cells

...ing mice with an efficiency that is similar to, or better than, viral vectors and with no observable toxic effect, according to a paper published this week in Proceedings of the National Academy of Sciences. The paper describes how the UB scientists used gene-nanoparticle complexes to activate adult brain ...

When it comes to cell entry, being average has its advantages

...u know how viruses get into cells, you know how to better design drugs to keep them out," said L.B. Freund, professor of engineering at Brown. "Or if you do want molecules to get in ?those in medication, say ?knowing an optimal particle size for entry is also helpful. "With nanotubes, we may be able to man...

In addition, tissue engineers may be able to use modified collagen in the lab to help control the formation of tiny new blood vessels that can be used to prom...

Brown-Harvard team solves mobile DNA's surgical sleight-of-hand

...e parts and how they fit together, you have a much better understanding of how the process works," Landy said. "So this work represents a major leap." When the lambda virus inserts its DNA into E. coli, λ-INT is the major player in the process, literally snipping the E. coli DNA strands before insertion an...
