Fiber optics

Taara has been developing tech to deliver connectivity across communities without underground cables over the last few years. For its latest trick, the Google spinoff is now providing fast internet access across cities using invisible beams of light.

For years, Alphabet's Taara has been delivering internet connectivity in remote areas with traffic-light-sized transmitters that communicate over long distances using beams of light. The tech has now been reduced down to a fingernail-sized chip.

A new study has demonstrated that a tiny bundle of optical fibers can continuously, accurately, and simultaneously measure six biomarkers of brain health, helping to prevent serious complications that can follow a traumatic brain injury.
