Better Bioimaging with a Liquid Lens

A new handheld probe uses near-infrared light and a liquid lens to create sharp three-dimensional images of lesions beneath the skin, in a few seconds. The device, allows doctors to peer two millimeters below the skin's surface to see, in particular, whether the cells beneath a mole show signs of being cancerous. If proved reliable, the probe could sharply reduce the number of biopsies that are necessary.

Wearable Scanner Opens New Frontier in Neuroscience

A tiny wearable /mobile PET (Positron Emission Tomography) scanner has been used to track chemical activity in the brains of unrestrained animals for the first time. By revealing neurological circuitry as the subjects perform normal tasks, researchers say, the technology could greatly broaden the understanding of learning, addiction, depression, and other conditions.
