Mild noise damage can be detected by cells in the inner ear
Damage to the inner ear as a result of environmental
noise is a major cause of deafness in the developed world. In new research, scientists now report evidence that the delicate sensory hair cells of the inner ear might react to being damaged by triggering calcium signals in surrounding tissues. The fi...

implications, but it could also have dietary repercussions. "It suggests that a consumer can reduce her or his intake of the persistent organic pollutants by changing to a formulation that contains less cod liver oil, and that contains a proportion o...
Impaired sense of smell increases risk for certain hazards

cues that can warn of potentially life-threatening situations, like fires, spoiled food or gas leaks. Sense of smell can be impaired by head trauma, viral infection, nasal obstruction or septal deviation, neurologic disorders, medications, hormonal ...
