Without preclinical testing, we wouldn’t have today’s life-saving cancer drugs. After all, scientists need to make sure a treatment works in animals before they can test it on people. This stage of ...

Variable reluctance (VR) sensors transform mechanical motion into electrical signals by exploiting changes in magnetic flux. As a ferromagnetic target moves past the sensor’s pole piece, the ...

An electrochemical sensor developed at Oregon State University holds promise for making food quality testing faster, more accurate, more environmentally friendly, and less expensive. The novel sensor, ...
