Most patients with severe tinnitus experience high levels of distress, especially men, older adults, and those with co-existing conditions.
Researchers at UC Berkeley found that humans gain a performance advantage from cross-nostril comparisons when tracking scents. With training, humans can improve their accuracy significantly and nearly double their speed. This discovery challenges the common assumption that humans are poor smellers compared to other mammals.
Researchers found that breast-feeding counters genetic tendencies toward ear infections, which can lead to learning difficulties and language development issues. The study identified specific genes involved in the vulnerability, but found that breast-feeding effectively neutralized their impact.
A study published in the Journal of Surgical Research found that reducing surgical resident work hours did not significantly improve perceived quality of patient care. Residents reported fewer fatigue-related errors but more continuity and communication issues.
A UK researcher has won a major science prize for his work on the region of the brain that helps us hear someone in a noisy place. The researcher, Sam Irving, is studying how the brain adapts to hearing loss and uses feedback systems to compensate.
A new study found that giving parents a 'wait-and-see' approach for treating ear infections significantly reduced the use of antibiotics, with little difference in outcomes for the children. The approach also interrupted the cycle of antibiotic prescription, reducing adverse effects and costs.
Researchers at Iowa State University are testing combustion for NASA using a new technology called electric particulate suspension. The goal is to understand how powders burn and ignite under various conditions, which could lead to improved fire safety and the development of a new safety standard.
Composer Dmitri Tymoczko has developed a geometric model to understand musical structure, representing every conceivable chord as a point in space. This approach helps connect familiar harmonies with dissonant cluster-type harmonies, revealing the melodic relationship between chords.
Researchers trained adult ferrets to localize sounds despite obstructed hearing, finding that frequency of training was crucial for improvement. The study showed that the brain can adapt to abnormal spatial cues rapidly with intensive training, suggesting potential benefits for patients with hearing disorders.
A new study from the University of Michigan Medical School found that a particular surgical procedure, the middle cranial fossa (MCF) approach, can preserve hearing in patients with small acoustic neuromas. The study examined 73 patients and reported a high rate of success, with three-quarters retaining useful hearing after tumor removal.
Researchers found that people exposed to loud noise over several years were 1.5 times more likely to develop acoustic neuroma, a slow-growing tumor that presses the cranial nerve responsible for sensing sound and balance. Wearing ear protection was associated with similar risk levels as non-exposure.
Researchers found that elevated homocysteine in blood may be a biomarker for increased AMD risk, particularly among advanced stages. High levels were also associated with higher AMD risk, highlighting the need for further study on prevention and treatment.
Researchers found that people with early dementia tend to rely more on familiar information pathways due to poor attentional control. This can lead to struggles with everyday tasks that require processing multiple pieces of information.
Researchers have developed more sensitive tests to predict Alzheimer's disease and cognitive decline. These implicit-memory tests outperform the commonly used Mini Mental exam, which is mainly sensitive to episodic memory. The new tests are strong predictors of Alzheimer's diagnosis two years early.
Daniel Gallie's research doubles protein content of corn grain, increasing its value for producers and providing a nutritious source for millions suffering from protein-energy malnutrition. The high-protein corn can be easily applied to sweet corn, offering a solution for those relying on plant-based sources.
Researchers at UC Berkeley found that humans can reliably discern the source of an odor when presented with it through one nostril. The brain's primary olfactory cortex is divided into separate areas for each nostril, allowing for accurate localization. This ability has implications for various fields, including truffle hunting.
Researchers at Cold Spring Harbor Laboratory have isolated the ramosa1 gene, which controls flower-bearing branch arrangement in corn. This gene played a key role in suppressing branching in early domesticated corn, leading to straight rows of kernels and compact ears. The study also reveals that plants with different levels of ramosa1...
A recent study found that a 'watch and wait' approach to treating kids' ear infections could significantly reduce the overuse of antibiotics. The study surveyed over 2,000 parents in Massachusetts communities, revealing mixed attitudes towards this treatment method.
A study found that piercing ear cartilage increased the risk of infection compared to lobe piercing. The authors identified 7 confirmed Pseudomonas aeruginosa infections and 18 suspected cases, with most treated ineffectively with antibiotics.
Research by Wake Forest University Baptist Medical Center reveals that hearing can significantly improve the ability of individuals with mildly impaired eyesight to locate objects in space. The study found that when sound was added, participants with nearsightedness were able to perform as well as those with normal vision.
Research confirms a direct link between small jaws, breathing difficulties, and increased risk of bed-wetting and ear infections in children. Orthodontic treatment has been shown to be effective in reducing or eliminating these issues, offering an alternative to traditional medication or ear tubes.
Researchers discovered the YB-1 protein's Cold Shock domain, resembling a bucket with handle and two ears, attaches DNA to its binding site. The domain alone forms weak bonds to DNA, contradicting previous measurements of complete protein strength.
Researchers studied how angle of riblets on pipe affect fluid flow, finding that diverging riblets speed up airflow by reducing turbulence. This study may also aid biologists in understanding the function of pit organs on sharks.
Researchers discovered that fusiform cells in the cochlear nucleus integrate acoustic information with head and ear position information to pinpoint sound sources. The study found that synapses transmitting acoustic information are stable, while those carrying head and ear position information exhibit plasticity.
A single geophone can detect seismic vibrations in Europa's icy crust, revealing its depth and potentially life-sustaining liquid ocean beneath. The technique, tested on Arctic Sea ice, aims to uncover the moon's internal structure without the need for a costly lander mission.
A systematic review found that ear thermometry is not a reliable method for measuring infants' body temperature, with wide individual differences and potential overestimation or underestimation of temperatures. This raises concerns about the accuracy of fever detection and precise temperature measurement in clinical settings.
The study identified the gene responsible for producing ear wax as being located on chromosome 16, near another gene linked to paroxysmal kinesigenic choreoathetosis. This discovery may shed light on the development of apocrine glands and their secretory products.
A survey of university undergraduate students found that over half had body piercings, while only 23% had tattoos, with piercing complications being the most common issue. Medical experts noted that tattooing may pose a risk for certain infections, but further studies are needed to confirm this.
Researchers created a new database of acoustic measurements to help engineers build customized sound systems. The database aims to improve human-computer interaction by enabling spatial sound with accurate location and depth perception.
