Gene expression patterns may help predict risk and progression of prostate cancer

This study lends support for such a hypothesis." The researchers also created a gene model using GeneSpringT...When male fish hum, females swim in, thanks to hormones, adaptable hearing

"We suspected that enhancing the sensitivity of the females' ear to the upper harmonics of the males' hums should improve detection of their vocalization," said Bass, who is a professor of neurobiology and behavior.
