Mushroom farmers are moving their outdoor operations into large greenhouses, shifting environmental factors away from external climates and toward internal microclimates. Environmental monitoring systems are installed in greenhouses to collect microclimate data. No sensor can directly measure mushroom growth to determine when adjustments are needed. Now scientists have come up with a GigE Camera solution. [..]

Photoacoustic microscopy (PAM) is a new imaging technique that employs laser light to induce ultrasonic vibrations in tissue. It can detect cancerous tissue, image-changing blood flow in the brain, and even identify individual cancer cells. Because of its narrow depth of field, PAM can only focus on a thin layer of tissue at a time. [..]

Strain sensors have demonstrated mechanically invisible monitoring of soft-bodied systems that are otherwise challenging for silicon-based rigid counterparts.
