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 Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
