    Hearing aids may delay cognitive decline

    Wearing hearing aids may delay cognitive decline in older adults and improve brain function, according to promising new research. Researchers have tested the use of hearing aids in almost 100 adults aged 62-82 years with hearing loss. After 18 months of hearing aid use, researchers found speech perception, self-reported listening disability and quality of life had significantly improved for participants. …read more

    Gene catalog comprising community of microbes in vaginal microbiome

    Researchers have created the first catalogue of genes that comprise the community of microbes, which inhabit the human vagina. The catalogue, called human vaginal non-redundant gene catalog (VIRGO), was recently released as a public resource that can be used by researchers to facilitate a more in-depth understanding of the role of vaginal microorganisms in women’s health and to potentially develop future treatments. …read more

    Scientists make most sensitive measurements to date of silicon’s conductivity

    Silicon, the best-known semiconductor, is ubiquitous in electronic devices including cellphones, laptops and the electronics in cars. Now, researchers at the National Institute of Standards and Technology (NIST) have made the most sensitive measurements to date of how quickly electric charge moves in silicon, a gauge of its performance as a semiconductor. Using a novel method, they have discovered how silicon performs under circumstances beyond anything scientists could test before‚ÄĒspecifically, at ultralow levels of electric charge. The new results may suggest ways to further improve semiconductor materials and their applications, including solar cells and next-generation high-speed cellular networks. The NIST scientists report their results today in Optics Express. …read more

    Freshwater flowing into the North Pacific plays key role in North America’s climate

    Massive freshwater river flows stemming from glacier-fed flooding at the end of the last ice age surged across eastern Washington to the Columbia River and out to the North Pacific Ocean, where they triggered climate changes throughout the northern hemisphere, new research published today in Science Advances shows. …read more

    Bilingual mash ups: Counterintuitive findings from sociolinguistics

    A new study exposes the fallacy of relying on pronunciation as a measure of linguistic proficiency. The study, ‘Revisiting phonetic integration in bilingual borrowing’, by Shana Poplack, Suzanne Robillard, Nathalie Dion (all from the University of Ottawa), and John. C. Paolillo (University of Indiana Bloomington) will be published in March 2020 issue of the scholarly journal Language. …read more
