 Reconnecting severed blood vessels is mostly done the same way today -- with sutures -- as it was 100 years ago, when the French surgeon Alexis Carrel won a Nobel Prize for advancing the technique. Now, a team of researchers at the Stanford University School of Medicine has developed a sutureless method that appears to be a faster, safer and easier alternative.

 Ongoing research at the Institute of Food Research, which is strategically funded by BBSRC, is exploring the use of virus-produced proteins that destroy bacterial cells to combat potentially dangerous microbial infections. Bacteriophages produce endolysin proteins that specifically target certain bacteria, and IFR has been studying one that destroys Clostridium difficile, a common and dangerous source of hospital-acquired infections.

A new physics-based theory could give researchers a deeper understanding of the unusual, slow dynamics of liquids composed of large polymers. This advance provides a better picture of how polymer molecules respond under fast-flow, high-stress processing conditions for plastics and other polymeric materials.

 Researchers are able to achieve extremely high-resolution microscopy through a process known as stimulated emission depletion (STED) microscopy. This cutting-edge imaging system has pushed the performance of microscopes significantly past the classical limit, enabling them to image features that are even smaller than the wavelength of light used to study them.
