Nanowires as Sensors in New Type of Atomic Force Microscope

19-Oct-2016

A new type of atomic force microscope (AFM) uses nanowires as tiny sensors. Unlike standard AFM, the device with a nanowire sensor enables measurements of both the size and direction of forces. Physicists at the University of Basel and at the EPF Lausanne have described these results in the ...

Scientists find new metabolic pathways to resist viruses

14-Oct-2016

Viral infection is one of the leading medical challenges of the 21st Century, ranging from the Hepatitis C Virus (HCV) epidemic affecting 3% of the global population, to recent outbreaks of West Nile, Zika, and Ebola viruses. Viruses are parasites that lack the basic metabolic machinery needed to ...

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 ...
