The increasingly ambiguous divide between man and machine just got blurred that much more with Stanford's recent announcement: scientists have successfully created the first truly biological transistor made entirely out of genetic material.
Guys who imitate Luciano Pavarotti or Justin Bieber to get the girls aren't alone. Male mice may do a similar trick, matching the pitch of other males' ultrasonic serenades.
The mice also have certain brain features, somewhat similar to humans and song-learning birds, which they may use to change their sounds, according to a new study.
"We are claiming that mice have limited versions of the brain and behavior traits for vocal learning that are found in humans for learning speech and in birds for learning song," said Duke neurobiologist Erich Jarvis, who oversaw the study. The results appear Oct. 10 in PLOS ONE and are further described in a review article in Brain and Language.
The discovery contradicts scientists' 60-year-old assumption that mice do not have vocal learning traits at all. "If we're not wrong, these findings will be a big boost to scientists studying diseases like autism and anxiety disorders," said Jarvis, who is a Howard Hughes Medical Institute investigator. "The researchers who use mouse models of the vocal communication effects of these diseases will finally know the brain system that controls the mice's vocalizations."
Jarvis acknowledged that the findings are controversial because they contradict scientists' long-held assumption about mice vocalizations....

El antibiótico minociclina proporciona modestas pero significativas mejoras en el funcionamiento y el estado de ánimo de los niños con síndrome X frágil (SXF), según concluye un estudio publicado en la edición de abril de 'Journal of Development...
Habits are behaviors wired so deeply in our brains that we perform them automatically. This allows you to follow the same route to work every day without thinking about it, liberating your brain to ponder other things, such as what to make for dinner.
However, the brain's executive command center does not completely relinquish control of habitual behavior.
