Bristol to lead revolutionary research into 'self-healing' materials

12-Jan-2018

The Manufacturing Immortality Project is a three-year project, funded by the Engineering and Physical Sciences Research Council (EPSRC), that will investigate the development of new materials made up of biological and non-biological parts which are capable of self-healing. Initially the project ...

Potential for a green energy economy based on hydrogen

First Characterization of a Sensory [FeFe] Hydrogenase

11-Jan-2018

Hydrogenases are enzymes capable of making hydrogen gas (H2) using protons from water, a reaction with relevance to a potential future green energy economy based on H2. Bacteria containing these enzymes often produce H2 as a waste product during sugar metabolism in the absence of oxygen. ...

Bacteria self-organize to build working sensors

12-Oct-2017

Researchers at Duke University have turned bacteria into the builders of useful devices by programming them with a synthetic gene circuit. As a bacterial colony grows into the shape of a hemisphere, the gene circuit triggers the production of a type of protein to distribute within the colony that ...

Bacteria stab amoebae with daggers

22-Aug-2017

Researchers from ETH Zurich and the University of Vienna have discovered a type of bacteria that uses tiny daggers to prevent itself from being eaten by amoebae. The scientists also resolved the three-dimensional structure of the mechanism that allows the micro-daggers to be shot ...

Researchers discover Achilles' heel of bacteria

07-Aug-2017

Salmonellae are particularly resistant to antibiotics since they possess not only one, but two membranes that protect them from harmful substances. This makes them members of the so-called Gram-negative bacteria. Since Salmonella infections are becoming increasingly difficult to treat with ...
