Electronic nose prototype may be worn for safety-sniffing

(Phys.org) -- A UK company has developed an electronic nose that the company says can make a real difference, as a fast-acting device for detecting harmful substances in the environment. Peratech claims its electronic nose ...

In a new microchip, cells separate by rolling away

Cell rolling is a common mechanism cells use to navigate through the body. During inflammation, for example, the endothelial cells that line blood vessels present certain molecules that attract white blood cells just enough ...

New method to examine batteries -- MRI from the inside

There is an ever-increasing need for advanced batteries for portable electronics, such as phones, cameras, and music players, but also to power electric vehicles and to facilitate the distribution and storage of energy derived ...

New driving force for chemical reactions discovered

New research just published in the journal Science by a team of chemists at the University of Georgia and colleagues in Germany shows for the first time that a mechanism called tunneling control may drive chemical reactions ...

Rapid, high-definition chemistry with new imaging technique

With intensity a million times brighter than sunlight, a new synchrotron-based imaging technique offers high-resolution pictures of the molecular composition of tissues with unprecedented speed and quality. Carol Hirschmugl, ...

See how they grow: Monitoring single bacteria without a microscope

(PhysOrg.com) -- With an invention that can be made from some of the same parts used in CD players, University of Michigan researchers have developed a way to measure the growth and drug susceptibility of individual bacterial ...

MRI zooms in on microscopic flow (w/ Video)

(PhysOrg.com) -- MRI images of water flow through a constricted microfluidic channel with the XZ axis on the left and the YZ axis on the right. Note that fast moving components directly aligned with the constricted region ...
