ScienceDaily (Jan. 20, 2012) — Scientists have developed a new way to create Terahertz waves (T-rays) that may one day lead to biomedical detective devices similar to the 'tricorder' scanner used in Star Trek
The scientists say that the T-ray scanner and detector could provide part of the functionality of a Star Trek-like medical 'tricorder' -- a portable sensing, computing and data communications device -- since the waves are capable of detecting biological phenomena such as increased blood flow around tumorous growths. Future scanners could also perform fast wireless data communication to transfer a high volume of information on the measurements it makes.
Ah, I love SD. As a Voyager fan, I would love to see one in action lol.
