Case study: Hearing loss in one infant twin affects mother’s speech to both babies

Case study: Hearing loss in one infant twin affects mother’s speech to both babies

Is it possible that hearing loss in one infant from a pair of twins can affect the mother’s speech to both infants? A new acoustics study zeroes in on this question and suggests that not only is this alteration of speech entirely possible, but that mothers speak to both infants as if they are hearing impaired. The study explores the acoustic characteristics of three mothers’ speech towards their infant twins. Continue reading

First atlas of body clock gene expression informs timing of drug delivery

First atlas of body clock gene expression informs timing of drug delivery

A new effort mapping 24-hr patterns of expression for thousands of genes in 12 different mouse organs — five years in the making — provides important clues about how the role of timing may influence the way drugs work in the body. A study detailing this veritable “atlas” of gene oscillations, never before described in mammals, is published this week in the Proceedings of the National Academy of Sciences Continue reading

Designer ‘barrel’ proteins created

Designer ‘barrel’ proteins created

Proteins are long linear molecules that fold up to form well-defined 3D shapes. These 3D molecular architectures are essential for biological functions such as the elasticity of skin, the digestion of food, and the transport of oxygen in blood Continue reading

Competition keeps health-care costs low, U.S. researchers find

Medical practices in less competitive health-care markets charge more for services, according to a study conducted by researchers at the Stanford University School of Medicine and the National Bureau of Economic Research. The study, based on U.S Continue reading

Smoking interferes with neurocognitive recovery during abstinence from alcohol

Smoking interferes with neurocognitive recovery during abstinence from alcohol

Numerous studies have shown that individuals with an alcohol use disorder perform worse than those without one on multiple neurocognitive domains of function following detoxification from alcohol, although the level of impairment can vary widely among individuals. A new study of the degree of neurocognitive recovery in treatment-seeking alcohol dependent individuals (ALC) — with varied degrees of smoking status — during the first eight months of sustained abstinence from alcohol has found that smoking status influenced the rate and level of recovery Continue reading

Bar attendance supports heavy drinking by young adults in the US-Mexico border region

Due to a legal drinking age of 18 years, cheaper alcohol, and marketing tactics of local bars that specifically target youth, Mexico is an attractive and geographically nearby destination where younger U.S. residents legally drink heavily Continue reading
