(Max-Planck-Gesellschaft) Zebra finches use their specialized song system for simple communication.
Using ultrasound technology to visualize the tongue’s shape and movement can help children with difficulty pronouncing “r” sounds, according to a small study. The ultrasound intervention was effective when individuals were allowed to make different shapes with their tongue in order to produce the "r" sound, rather than being instructed to make a specific shape.
Center for Nanoscale Materials users from Toyota Research Institute of North America, working with CNM's Nanophotonics Group, have determined that bulk coherent acoustic vibrations are heavily damped by scattering from radially aligned nanosized pores within hypersonic crystals of closely packed colloidal silica. Surface acoustic modes are much less influenced, suggesting new ways to manipulate thermal transport via phonon propagation control.
Frogs are well-known for being among the loudest amphibians, but new research indicates that the development of this trait followed another: bright coloration. Scientists have found that the telltale colors of some poisonous frog species established them as an unappetizing option for would-be predators before the frogs evolved their elaborate songs. As a result, these initial warning signals allowed different species to diversify their calls over time.
Music therapy reduces depression in children and adolescents with behavioral and emotional problems, a study has found.
A new study provides the first known evidence of how a similar acoustic characteristic in the cry sounds of human infants and rat pups may be used to detect the harmful effects of prenatal cocaine exposure on nervous system development.
Hitachi today announced that, in collaboration with Professor MIURA Kiyotaka of the School of Engineering, Kyoto University, it has successfully achieved read/write of digital data in 100 layers of fused silica glass, a recording density comparable to Blu-ray Disc. One hundred multi-layer data recording was verified by the application of newly developed noise reduction technology to overcome interference from data recorded on other layers while trying to access data written in deeper layers within the fused silica glass.
In the last 8 months a fully robotic telescope in Tenerife has been carrying out high-precision observations of the motion of stellar surfaces. The telescope is the first in the SONG telescope network and a milestone in a new global stellar research project, aiming at making it possible to follow the stars twenty-four seven.
(University of North Carolina Health Care) A new study conducted by University of North Carolina School of Medicine researchers provides the first known evidence of how a similar acoustic characteristic in the cry sounds of human infants and rat pups may be used to detect the harmful effects of prenatal cocaine exposure on nervous system development.
Biologists found the could quite accurately predict what type of predator was threatening a squirrel by analyzing its sounds and tail movements.
Subjective screening questions do not reliably identify teenagers who are at risk for hearing loss, according to researchers. Their study results suggest that objective hearing tests should be refined for this age group to replace screening questions.
Google's music-subscription service will try to anticipate its listeners' mood swings as it amplifies its competition with Pandora, Spotify and other popular services that play tunes over the Internet.
If growing vegetables in a box with no soil and out of direct sunlight sounds a little fishy, well, it is.
Whirring back and forth on a turning turret, the white, 40-foot dish evokes the aura of movies such as "Golden Eye" or "Contact," but the University of Arizona team of scientists and engineers that commissioned it earlier this month isn't planning to listen for signals from extraterrestrials or hijack satellites.
(University of Miami) Over two years of observation McRae, working closely with professor of biology Steven Green, found that he could quite accurately predict what type of predator was threatening a squirrel by analyzing its sounds and tail movements.
Scientists have restored the hearing of mice partly deafened by noise, using advanced tools to boost the production of a key protein in their ears. By demonstrating the importance of the protein, called NT3, in maintaining communication between the ears and brain, these new findings pave the way for research in humans that could improve treatment of hearing loss caused by noise exposure and normal aging.
WASHINGTON (AP) -- It sounds like a broken record: Last month again set a new mark for global heat. And meteorologists say Earth is now on pace to tie the hottest year ever recorded, or more likely, to break it....
Ryan McKellar’s research sounds like it was plucked from Jurassic Park: he studies pieces of amber found buried with dinosaur skeletons. But rather than re-creating dinosaurs, he uses the tiny pieces of fossilized tree resin to study the world in which the now-extinct behemoths lived. New techniques for investigating very tiny pieces of fragile amber buried in dinosaur bonebeds could close the gaps in knowledge about the ecology of the dinosaurs.
