The program has expanded to include activities on maternal and child health, young people's health and infectious diseases.
Scientists have discovered a gene that acts as a 'brake' on hair-cell regeneration in the inner ear. By deleting this gene, hair cells can proliferate and potentially regenerate, providing new hope for treating age-related hearing loss. This breakthrough opens up new avenues for research and potential clinical applications.
A new test for tinnitus evaluates loudness and pitch using an automated procedure. Veterans are found to be more independent in daily activities and less physically disabled than their peers residing in community nursing homes, suggesting the impact of extensive rehabilitation services available to veterans.
A recent study published in Proceedings of the National Academy of Sciences reveals that the brain can be retrained to process sound in an alternative way, allowing for improved hearing sensitivity. This new system enables neurons to selectively fire at specific volume levels, making it more responsive to subtle changes in loudness.
Research found no significant association between serum cotinine levels and hearing loss, contradicting previous reports. The study included 197 patients with new hearing loss and 394 without, but noted the need for further longitudinal studies to clarify the relationship.
Researchers used fMRI to study brain activity in people with dyslexia, finding increased visual pathway activation during auditory tasks, linked to poorer performance. The findings suggest abnormal cross-modal sensory processing may be a fundamental deficit in dyslexia.

A study found that a common newborn hearing test may give false positives in as many as 35% of cases, leading to unnecessary worry and costs for follow-up tests. In contrast, a more complex test gave normal-hearing babies a passing grade nearly all the time.
Researchers warn that children born with persistent pulmonary hypertension (PPHN) may be at risk for progressive hearing loss, even if standard auditory testing proves normal in the first weeks of life. Periodic hearing tests every six months until age 3 are recommended to avoid delayed diagnosis and its associated costs.
