These clusters aim to improve hearing loss prediction, diagnosis, and treatment, as well as animal navigation research. The funding enables the continuation of high-quality research with social relevance.
Researchers found that 90% of participants had at least one sign of dry eye disease, with significant progression after one year. The study highlights the need for early detection and advice on managing the condition through simple methods such as taking screen breaks and maintaining a healthy lifestyle.
Researchers at Karolinska Institutet have developed a method to track the development of cells in the nervous system and inner ear. The technique, known as ectoderm barcoding, reveals that cells in the inner ear develop from two main types of stem cells.
Researchers at UC Santa Barbara created deaf mosquitoes and found that males had no interest in mating, even when left with females for days. The absence of a single gene, trpVa, is responsible for this effect, which could have major implications for managing disease transmission by controlling mosquito populations.
