songs about the winged life like “Marching Jaybird” by Etta Baker, “Birds” by Neil Young, and “I’m a Cuckoo” by Belle and Sebastian. “If we’re going to give birds music, we might as well give them what we consider to be our masterpieces. But the on...
Exploring the dark matter of the genome
...tructure of genomes affects cellular processes. We hear
too much about the 'post-genomic era' -- it's underappreciated that we don't understand the genome yet." Celniker agrees. "What we would like to see is a complete sequence of the fruit fly from telomere to telomere" -- that is, from one end of th...
Eavesdropping comes naturally to young song sparrows

and memorize songs sung by adult birds. The following spring, when the young birds are establishing their own territory, they modify and prune their repertoire so their songs are more similar to their neighbors’. A song sparrow’s repertoire crystal...

a series of low- and high-frequency tones as well as some novel sounds. Patients were asked to respond by pressing a button every time they heard the high frequency tone, also known as the “oddball?tone, which generates ERPs in the EEG. Generally, in...

Slow brain waves play key role in coordinating complex activity

the sound, analyze it, extract the relevant information, formulate a response, and then coordinate your lips and mouth to speak. We have no idea how information moves between these areas." By measuring electrical activity in the brains of pre-surgic...

a male singing, they race over to the speaker," Brockmann said. "The fall females are much more hesitant. They take longer and seem reluctant to approach the speaker." Brockmann said although scientists have examined similar phenomena in other spe...
Mirrors in the mind: New studies elucidate how the brain reflects onto itself the actions of others
...when monkeys perform certain actions and when they hear
the same actions being performed. In the new work, the researchers report new evidence for an auditory mirror system existing in humans as well. When subjects were presented with sounds corresponding to mouth actions (such as crunching candy, kissi...
To elude bats, a moth keeps its hearing in tune
It has been known for over 50 years that moths can hear
the ultrasonic hunting calls of their nocturnal predator, the bat. Moth ears are among the simplest in the insect world—they have only two or four vibration-sensitive neurons attached to a small eardrum. Previously, it was thought that these ears wer...
