Deaf children who receive cochlear implants do better learning language and speech the younger they receive the implants, according to research by scientists at Indiana University School of Medicine.
However, its not clear whether implanting children before they turn age one is worth the potential risks associated with such early surgeries, the researchers said. The work will be presented next week at a meeting of the Acoustical Society of America.
The study, by Mario Svirsky, Ph.D., professor of otolaryngology-head and neck surgery, and Rachael Holt, Ph.D., post-doctoral fellow in otolaryngology-head and neck surgery, also supports the theory that there is a "sensitive period" for optimal language development during the early years of life. In the study, the speed at which language was learned was greater for children who received cochlear implants earlier. The implants provide congenitally deaf children with a sense of hearing, but the children must learn how to interpret the sounds the implants provide. The researchers studied 96 children who received the implants in their first, second, third and fourth years of life, evaluating their progress with language skills and speech perception every six months. Those who received the implants earlier consistently performed better on tests of language skills -- learning vocabulary, grammar, and other such language rules -- and speech perception -- their ability to understand spoken words -- than did those who received the implants later. "Not only is earlier better, but we found that language gains tended to be faster for children who received cochlear implants earlier in life," said Dr. Svirsky.

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.
Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
