Researchers are using liquid crystals to create incredibly small, swirling schools of 'fish.' The fish in this case are minute disruptions in the orientations of the molecules that make up solutions of liquid crystals.
Novel nanoprobes show promise for optical monitoring of neural activity
Researchers have developed ultrasensitive nanoscale optical probes to monitor the bioelectric activity of neurons and other excitable cells. This novel readout technology could enable scientists to study how neural circuits function at an unprecedented scale by monitoring large numbers of individual neurons simultaneously. It could also lead to high-bandwidth brain-machine interfaces with dramatically enhanced precision and functionality.
