Why Wolves Are Forever Wild, but Dogs Can Be Tamed

Dogs and wolves are genetically so similar, it's been difficult for biologists to understand why wolves remain fiercely wild, while dogs can gladly become "man's best friend." Now, doctoral research by evolutionary biologist Kathryn Lord at the University of Massachusetts Amherst suggests the different behaviors are related to the animals' earliest sensory experiences and the critical period of socialization.

Regenerate Sensory Hair Cells, Restore Hearing to Noise-Damaged Ears

Hearing loss is a significant public health problem affecting almost 50 million people in the United States alone. Sensorineural hearing loss is the most common form and is caused by the loss of sensory hair cells in the cochlea. Hair cell loss results from a variety of factors including noise exposure, aging, toxins, infections, and certain antibiotics and anti-cancer drugs. Although hearing aids

Ion Channels | TRP Channels in Drosophila Auditory Transduction

In this study, Lehnert et al. record spikes and subthreshold activity from a genetically defined population ofDrosophila auditory receptor neurons. These recordings reveal that several TRP family members play distinct roles in converting movement to transduction currents.Lehnert et al.Neuron, Volume 77, Issue 1, 115-128, 9 January 201310.1016/j.neuron.2012.11.030

Hearing Impairment: A Panoply of Genes and Functions

Research in the genetics of hearing and deafness has evolved rapidly over the past years, providing the molecular foundation for different aspects of the mechanism of hearing. Considered to be the most common sensory disorder, hearing impairment is genetically heterogeneous. The multitude of genes affected encode proteins associated with many different functions, encompassing overarching areas of research.
