In order to regain their sense of hearing, many deaf people currently opt for cochlear implants
. Such devices are expensive, however, plus they must be surgically installed and
they don't work on all forms of hearing loss. That's why a group of researchers at Colorado State University (CSU) are developing an alternative – an electric retainer that transmits spoken words to the user by buzzing their tongue.
There may come a day when certain plants in your workplace suddenly turn white, at which point everyone will run screaming from the building – those co-workers will have been right to do so, as the white plants indicated that a toxic gas was present. Before that scenario can take place, a little more work still needs to be done, and Colorado State University (CSU) biologist Dr. June Medford is doing it. Using a computer-designed detection trait, she is creating plants that stop producing chlorophyll when they detect pollutants or explosives in the air.
