Research challenges decades-old understanding of how we hear sound

Researchers at Linköping University, Sweden, have made several discoveries on the functioning mechanisms of the inner hair cells of the ear, which convert sounds into nerve signals that are processed in the brain. The results, ...

The bald truth—altered cell divisions cause hair thinning

Hair grows from stem cells residing in hair follicles. During aging, the capability of hair follicles to grow hair is successively lost, leading to hair thinning and ultimately hair loss. In a new study, researchers from ...

Molecular switch controls ability to repair hearing loss in mice

In a study in mice, Johns Hopkins Medicine researchers have found a molecular switch that turns off the animal's ability to repair damaged cells in the inner ear. The findings shed light on regenerative abilities that are ...

Fine-tuning stem cell metabolism prevents hair loss

A team of researchers from Cologne and Helsinki has discovered a mechanism that prevents hair loss: hair follicle stem cells, essential for hair to regrow, can prolong their life by switching their metabolic state in response ...
