| Babies need free tongue movement to decipher speech sounds Posted: 12 Oct 2015 03:08 PM PDT Inhibiting infants' tongue movements impedes their ability to distinguish between speech sounds, researchers have found. The study is the first to discover a direct link between infants' oral-motor movements and auditory speech perception. |
| New optoelectronic probe enables communication with neural microcircuits Posted: 12 Oct 2015 08:57 AM PDT The burgeoning field of optogenetics makes it possible for scientists to control brain activity using pulses of light. Now, researchers have developed an optoelectronic device which opens the possibility of bidirectional communication with the brain. The new technology enables stimulation of neural microcircuits with millisecond precision according to predescribed space-time maps while monitoring changes in neural activity across the targeted microcircuits. |
| Supercoiled DNA is far more dynamic than the 'Watson-Crick' double helix Posted: 12 Oct 2015 05:38 AM PDT Researchers have imaged in unprecedented detail the three-dimensional structure of supercoiled DNA, revealing that its shape is much more dynamic than the well-known double helix. |
| Epigenetic algorithm accurately predicts male sexual orientation Posted: 08 Oct 2015 11:16 AM PDT An algorithm using epigenetic information from just nine regions of the human genome can predict the sexual orientation of males with up to 70 percent accuracy, according to new research. Beyond the genetic information contained in DNA, the researchers examined patterns of DNA methylation across the genome in pairs of identical male twins. |
