University of Texas at Dallas researchers have developed a micro imaging device that could be used with an endoscope to spot cancers at an earlier stage.
The technology uses LED lighting and hyperspectral imaging to capture near-infrared and ultraviolet wavelengths in addition to the visible light that a conventional camera registers. The Erik Jonsson School of Engineering and Computer Science researchers published a study describing their compact prototype in the May/June issue of the Journal of Medical Imaging.
In a fruit fly, nerve cells that detect limb movement are silenced when the insect walks or grooms. This on-off switch may help the nervous system to shift between two states: one that supports postural reflexes that keep the body steady and another that readies it to move voluntarily. The fly’s ability to selectively suppress movement feedback, the researchers surmised, could make the insect more sensitive to sudden external events that would perturb it, and therefore quicker to respond.
