Researchers' new recipe cooks up better tissue 'phantoms'

Scientists have created a novel combination of additives that enable gelatin to mimic the acoustical and optical properties of soft tissue in humans. The resulting tissue 'phantoms' can be used to test photoacoustic and ultrasonic imaging technologies, which are increasingly being used in clinical applications.

Signals from the Atlantic salmon highway

Researchers use acoustic tags to track Atlantic salmon migration, finding valuable information about fish movements and survival rates. Early data suggest many young salmon are surviving their journey to the Labrador Sea and coastal West Greenland.

Female concave-eared frogs draw mates with ultrasonic calls

A new study reveals that female concave-eared torrent frogs emit high-pitched chirps spanning audible and ultrasonic frequencies to signal their interest. Males respond instantaneously, with impressive accuracy in localizing the sound, a feat shared only by elephants, humans, barn owls, and dolphins.

Call of the child

Researchers found that mothers' brains respond more quickly and robustly to ultrasonic calls of mouse pups, enabling them to detect and discriminate between sounds. This improvement in brain function is associated with the ability to recognize behaviorally significant sounds, such as those made by their young.

Mice have a gift for song

Researchers discovered that male mice produce ultrasonic calls with complex passages, syllable types, and regular time signatures, meeting the definition of song. The findings suggest that mouse song may approach that of many songbirds, opening new avenues for research into the genetic contributions to song and learning.

Illinois chemists spray their way to better catalysts

Illinois chemists have discovered a way to produce a highly porous network of molybdenum disulfide that preferentially exposes catalytic edges, improving sulfur removal efficiency. The new method uses ultrasonic spray pyrolysis and can be scaled up for industrial applications.
