PITTSBURGH—Gene regulatory networks in cell nuclei are similar to cloud computing networks, such as Google or Yahoo!, researchers report today in the online journal Molecular Systems Biology. The similarity is that each system keeps working despite the failure of individual components, whether they are master genes or computer processors.
This finding by an international team led [...]

Press release from PLoS Biology
As reported this week in the open-access journal PLoS Biology, an international team of scientists studying a rare genetic disease has discovered that a bundle of proteins already known to be important for keeping chromosomes together also plays an important role in regulating gene expression in humans. In addition to shedding [...]

How microbial neighbors settle differences
Even microbes are governed by the principle of supply and demand – at least at the genetic level. Not all of their gene products, the blueprints for proteins, are required at all times. That means most of their genes only become active when they are needed, as is the case in [...]

The ¤3 million, three-year study will use gene knock-out technology developed in Nottingham to study the function of genes in a ’super’ strain of the bacteria Clostridium difficile to discover why it causes more severe disease, kills more people, is harder to eradicate and more resistant to antibiotics.

Goal: Make the old heal like the young
Researchers have unraveled crucial details of how aging causes broken bones to heal slowly, or not at all, according to study results published today in the Journal of Bone and Mineral Research. The research team also successfully conducted preclinical tests on a potential new class of treatments designed [...]
