Spotting tomato blight with a smartphone

Researchers at North Carolina State University have developed portable technology that allows farmers to identify plant diseases in the field. The handheld device, which is plugged into a smartphone, works by sampling the ...

Atomic beams shoot straighter via cascading silicon peashooters

To a non-physicist, an "atomic beam collimator" may sound like a phaser firing mystical particles. That might not be the worst metaphor to introduce a technology that researchers have now miniaturized, making it more likely ...

Shrinking a medical lab to fit on a fingertip

Identifying a patient's viral infection or diagnosing a blood disorder usually requires a lab and skilled technicians. But researchers at Princeton University have developed a new technology that goes a long way toward replacing ...

Portable "tricorder" scans life signs

Scientists from the School of Engineering at the University of Glasgow have developed a handheld device for taking medical readings from patients, and transferring the data to a smartphone.

Adapting technology to image blood vessels in skin disease

Small vessel vasculitis—inflammation of the small blood vessels—appears as a stain of tiny, red dots covering the skin that, depending on the severity, can evolve into painful pustules or ulcers. In some patients, it ...

Researchers discover new way to power electrical devices
