First description of a triple DNA helix in a vacuum
Noticias de biología
A team of researchers at the Institute for Research in Biomedicine (IRB Barcelona) and the Barcelona Supercomputing Center (BSC) have managed for the first time to extract trustworthy structural information from a triple helix DNA in gas phase.
One of the most relevant biomedical consequences of this study is that it could avail the development of the so-called antigen therapy. This therapeutic approach, which is based on DNA triple helix structures, would switch off the activity of the genes involved in a given disease.

Mutations behind flu spread revealed
Noticias de biología
At a Royal Society meeting in London about H5N1 research yesterday, the thus-far silent scientist spoke openly about his results after the National Science Advisory Board for Biosecurity (NSABB), an independent advisory group to the US government, unanimously voted last week that Kawaoka’s paper should be published in full. Nature intends to “proceed with publication as soon as possible”.
His experiments began when he tweaked the H5N1 virus to reproduce in a ferret’s airways. He introduced random alterations into its haemagglutinin (HA) protein, which it uses to stick to host cells. From the resulting library of mutants, he isolated viruses with two mutations in HA — N224K and Q226L — that could stick to receptors in human tracheal cells. That is something H5N1 viruses cannot usually do....

Algae biofuels: the wave of the future
Noticias de biología
Researchers at Virginia Bioinformatics Institute at Virginia Tech have assembled the draft genome of a marine algae sequence to aid scientists across the US in a project that aims to discover the best algae species for producing biodiesel fuel. The results have been published in Nature Communications. Scientists in VBI's Data Analysis Core (DAC), Robert Settlage, Ph.D., and Hongseok Tae, Ph.D., assisted in the assembly of the genome of Nannochloropis gaditana, a marine algae that may be capable of producing the lipid yields necessary for a viable fuel source...

Study finds protective gene in fat cells
Noticias de biología
In a finding that may challenge popular notions of body fat and health, researchers at Beth Israel Deaconess Medical Center (BIDMC) have shown how fat cells can protect the body against diabetes. The results may lead to a new therapeutic strategy for preventing and treating type 2 diabetes and obesity-related metabolic diseases, the authors say...
