New approach uses light to stabilize proteins for study

Researchers report they have developed a new technique that uses light to control the lifetime of a protein inside the cell. This method will allow scientists to better observe how specific proteins contribute to health, development and disease.

Turning a dangerous toxin into a biosensor

Some bacteria release a toxin that forms pores on other cells. Scientists have studied the pore-forming toxin aerolysin and genetically engineered it to be used as a high-resolution sensor for biological molecules like DNA and proteins.

Brain tissue kept alive for weeks on an artificial membrane

This novel new system uses a microfluidic device that can keep tissue from both drying out and from drowning in fluid. A proof-of-concept experiment showed that tissue explanted from the mouse brain remained viable after almost one month in culture, much longer than is possible with other microfluidic culturing methods, and also much simpler.

Synthetic cells make long-distance calls

Synthetic biologists have designed a set of transcriptional circuits that, when added to (and expressed by) the genomes of single-cell microbes, allows them to quickly form a network of local interactions to spur collective action, even in large communities.
