How cells move

12-Oct-2016

It's a known fact that cells can move around the body, but how they do it has been unknown - until now. Researcher in Infection Medicine Pontus Nordenfelt at Lund University in Sweden has managed to describe and visualize cell migration on a molecular level. In time, this could become significant ...

New Sensor Could Help Fight Deadly Bacterial Infections

08-Sep-2016

Scientists have built a new sensor that can detect the potentially deadly E.coli bacteria in 15-20 minutes, much faster than traditional lab tests. E.coli can be transmitted in contaminated food and water, posing particular risks to children and the elderly. In the late spring of 2011 a serious ...
