Scientists identify a novel structure that converts sound waves to mechanical energy, enabling insects to hear at remarkable frequencies. The discovery could lead to breakthroughs in acoustic sensor design and development.
Researchers found that male house mice produce distinct song patterns, allowing females to distinguish between unrelated males. The complexity of their songs may play a role in attracting females.
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.
Researchers at Virginia Tech discovered that certain bats can deform their ears in just one-tenth of a second, changing their ultrasonic hearing patterns. This allows them to adapt to different acoustic sensing tasks, outperforming humans in spatial hearing sensitivity.
Researchers found unusual vocal patterns in BTBR mice, which could be used to model impaired communication in autism. The study suggests that these unique patterns may resemble those seen in some autistic infants and young children.
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.
A meta-analysis of 51 studies found that ultrasonic equipment was at least as effective and safe as conventional equipment, with reduced average blood loss in most procedures. Ultrasonic instruments also resulted in shorter surgery times and fewer complications such as blood clots and nerve injuries.
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.
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.
Researchers at Iowa State University have developed a technology that improves soy processing by increasing protein yield by 46% and sugar content by 50%. This breakthrough could generate up to $230 million per year in revenue through the production of low-cost, sugar-enriched whey.
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 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.
