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.
