 E-Mail The sense of hearing is, quite literally, a molecular tightrope act. Turns out, it involves acrobatics as well. In a paper published in Nature Communications on Feb 8, researchers at Harvard Medical School and Boston Children's Hospital show that a dynamic and delicate connection between two pairs of diminutive protein filaments plays a central role in in hearing. The tension held by these filaments, together called a tip link, is essential for the activation of sensory cells in the inner ear. The team's analyses reveal that the filaments, which are joined end-to-end, work together ...

Auditory pathways in the brainstem do not fully mature without microglia clearing away extra cell connections. This crucial function occurs even when pruning by microglia is delayed, according to new research published in eNeuro.

 E-Mail Stopping the spread of COVID-19 is difficult enough. It's even more complicated and confusing when information and resources provided by governments are largely inaccessible to a variety of disabled populations.
