Highly sensitive biosensor for measuring glucose in saliva

A new ultra-sensitive transistor-based biosensor developed by researchers at The Hong Kong Polytechnic University can measure the level of glucose in saliva. Fabricated by using a glucose oxidase nzyme layer, the biosensor ...

Image: Novel spectroscopy by using aberrations

When life gives you lemons, make lemonade. At Oak Ridge National Laboratory and Uppsala University, researchers have done the scientific equivalent by using, rather than eliminating, flaws inherent to electron microscopy ...

Asteroid-hunting spacecraft delivers a second year of data

NASA's Near-Earth Object Wide-field Survey Explorer (NEOWISE) mission has released its second year of survey data. The spacecraft has now characterized a total of 439 NEOs since the mission was re-started in December 2013. ...

Image: The turbulent North Atlantic

The Gulf Stream waters flow in somewhat parallel layers, slicing across what is otherwise a fairly turbulent western North Atlantic Ocean in this March 9, 2016 image collected by the Visible Infrared Imaging Radiometer Suite ...

In these microbes, iron works like oxygen

A pair of papers from a UW–Madison geoscience lab shed light on a curious group of bacteria that use iron in much the same way that animals use oxygen: to soak up electrons during biochemical reactions. When organisms—whether ...
