Bioceramic implant induces cranial regrowth

A bioceramic implant has proved to stimulate regeneration of natural skull bone, so that even large cranial defects can be repaired in a way that has not been possible before. The research, led from the University of Gothenburg, ...

Neuroscience

Improving the precision of bionic devices with light

For a person with normal hearing, sound waves travel in the fluid-filled cochlea of the inner ear, causing sensory hair cells to react and send signals to the brain via the auditory neurons. For those with hearing loss, these ...

New implant used to treat heart valve disease

Mitral regurgitation is one of the most common heart valve diseases, and requires treatment. In this disease, the mitral valve no longer closes tightly, causing blood to back up in the left atrium. Shortness of breath is ...
