Of mice and men: Deaf mouse leads scientists to new human hearing loss gene
...of all hearing loss in people under 30. Scientists estimate that half of all inherited hearing loss cases are due to mutations in a single gene called connexin 26, found in 1997. But researchers are still piecing together the other genes involved in the rest of the genetic deafness cases. The new TMIE gene wi...Drinking through your pelvic region?

Based on these differences, the scientists estimate the earliest common parasite ancestor must be 100,000 to 180,000 years old, a timeframe coincident with human population expansion out of Africa. "We speculate," says Dr. Su, "that when the human population grew, the malaria parasite grew with it."...Other highlights in the July 17 issue of JNCI
