A study published in the International Journal of Human Factors and Ergonomics found that an in-car alarm can cut crash rates for drivers over 60 by 50%, but had little effect on younger drivers. The team also discovered that female drivers under 35 responded safely to alarms, while males did not.
Researchers at Northwestern University have found a secret bodyguard for the ears - a newly discovered connection from the cochlea to the brain that warns of intense incoming noise. This novel pain system protects the ear from very loud or damaging noise, which may be why people jam their fingers in their ears when exposed to loud soun...
A study by New York University's Steinhardt School of Culture, Education, and Human Development found that crowdsourcing using Amazon Mechanical Turk can produce high levels of agreement among listeners, even when individual responses are not highly accurate. With samples of nine or more AMT users, performance converges with that of ex...
A new study at MIT reveals the secret to the iconic Cremonese violins' powerful sound: elongated f-holes and thicker back plates. Researchers found that makers may have inadvertently crafted these features, as small errors in craftsmanship led to evolutionary changes.
Research shows that fluctuations in river flows are increasing with climate change, scrounging away salmon eggs and exhausting young fish. Habitat restoration projects and reducing stormwater runoff can ease flooding and peak flows threatening salmon redds.
Research from Northeastern professor of psychology Iris Berent and her colleagues finds that linguistic preferences are guided by abstract rules rather than motor system simulation. Abstract rules trigger motor action, not the other way around.

Ring-tailed lemurs can match scents with sounds from the same female, indicating a stronger response when both cues are present. This ability may aid lemurs in detecting nearby individuals, as scents can linger after the animal has left the area.
A submarine canyon offshore from the strait that separates the U.S. and Canada supplies most of the water coming into Puget Sound, the Strait of Juan de Fuca and Canada's Georgia Strait. This intense flow and mixing contribute to the region's high productivity and mysterious ocean conditions.

A new study from RIKEN Brain Science Institute found that the pitch-accent in words pronounced in standard Japanese activates different brain hemispheres depending on whether the listener speaks standard Japanese or one of the regional dialects. Native speakers who acquire a second language later in life process pitch changes similarly...
Researchers developed a sound preconditioning protocol that protected mice from drug-induced hearing loss and increased expression of heat shock proteins in the inner ear. This finding suggests that sound therapy may protect hearing in patients requiring treatment with ototoxic drugs.
Researchers at the National Institutes of Health developed a sound preconditioning protocol that protects mice from ototoxic drug-induced hearing loss, inducing heat shock protein expression in the ear. The study suggests that sound therapy may protect hearing in patients requiring treatment with ototoxic drugs.
Researchers found that consumers are more likely to buy a product from a different location when a pleasant sound draws attention to the item. This effect is attributed to the ability to visually process products presented in the same spatial direction as the auditory signal, making it easier for consumers to make informed decisions.
A study by University of Alberta researcher Deryk Beal found that children who stutter have less grey matter in brain regions responsible for speech production. This discovery highlights the importance of early treatment approaches like those pioneered by the Institute for Stuttering Treatment and Research.
Research reveals that people experience a lower sense of agency for actions associated with negative outcomes, making blame harder to accept. The discovery sheds light on notions about personal responsibility and emotional experiences., People tend to take credit for good outcomes but struggle with accepting responsibility for bad ones.
