By Kimberly Flynn PISCATAWAY, NJ—Sensors in smartphones and smart speakers could help determine a person’s level of alcohol intoxication based on the changes in their voice, according to a new study in the Journal of Studies on Alcohol and Drugs. Researchers at Stanford Medicine and the University of Toronto conducted a small study of 18 adults ages 21 and up. Participants were given a weight-based dose of alcohol and randomly assigned a series of tongue twisters—one before drinking, and one each hour up to seven hours after drinking. The participants were asked to read the tongue twister aloud, and a smartphone was placed on a table withing ...

To slow the effects of climate change, conserve biodiversity, and meet the sustainable development goals, replanting trees is vital. Restored forests store carbon within the forest’s soil, shrubs, and trees. Mixed forests are especially effective at carbon storage, as different species with complementary traits can increase overall carbon storage. Compared to single-species forests, mixed forests are also more resilient to pests, diseases, and climatic disturbances, which increases their long-term carbon storage potential. The delivery of other ecosystem services is also greater in mixed species forests, and they support higher levels of biodiversity. Although the benefits ...

WHAT: A treatment to move blood from the umbilical cord into an infant’s body may provide a safe option for preterm infants born after 28 weeks who need rapid support, suggests a study supported by the National Institutes of Health. The procedure, called umbilical cord milking, involves gently squeezing the cord between the thumb and forefinger and pushing the blood into the newborn’s abdomen. The new findings suggest that concerns raised by a 2019 study of infants born before 28 weeks—which concluded that umbilical cord milking might increase the risk of bleeding inside the brain—do not apply to preterm infants born after 28 weeks. The ...

Osaka, Japan – Robots able to display human emotion have long been a mainstay of science fiction stories. Now, Japanese researchers have been studying the mechanical details of real human facial expressions to bring those stories closer to reality. In a recent study published by the Mechanical Engineering Journal, a multi-institutional research team led by Osaka University have begun mapping out the intricacies of human facial movements. The researchers used 125 tracking markers attached to a person’s face to closely examine 44 different, singular facial actions, such as blinking or raising the corner of the mouth. Every facial expression comes with a variety of local deformation ...

The effectiveness of live zoster (shingles) vaccine is highest in the first year after vaccination and then wanes substantially. But it continues to provide some protection against shingles and its complications ten years after vaccination, even in patients with a weakened immune system, finds a study published by The BMJ. Vaccine effectiveness is a measure of how well vaccines work to protect communities in the real world. Herpes zoster, commonly known as shingles, is a painful rash caused by reactivation of the chickenpox virus. It’s much more common among people aged 60 and older and those with a weakened ...

Some barnacles are ‘morphing’ to protect themselves from predatory warm-water sea snails, which are expanding into their territory due to climate change. Research led by the University of Southampton and published in the Journal of Biogeography shows how temperate prey species are adapting to changing water temperatures, which carry the threat of warm-water predators encroaching into their territory. As global sea-surface temperatures rise and the number of marine heatwaves increase under global heating, coastal marine communities are changing. Warm-water predators ...

Whether talking about the office kitchen, hiking trails or ratings on Yelp, there are always people who put in effort to leave those spaces better. There are also those who contribute nothing to that public good. New research using large-scale online experiments suggests that rewarding people to contribute to a virtual public good, such as a simulated online rating for a ferry system, increased the accuracy of the ratings and improved the overall quality of that resource. The multidisciplinary team, including researchers from the University of California, Davis; Hunter College, College of New York; the Max Planck Institute for ...

1 in 25 carries a genotype that is associated with a shortened lifespan Scientists at deCODE genetics, a subsidiary of Amgen, have published a study on actionable genotypes detected in the Icelandic population and their association with lifespan. The results of this study are among the things that have motivated the government of Iceland to announce a nationwide effort in precision medicine. As the delivery of precision medicine to a population requires considerable amount of data on genomics, transcriptomics and proteomics of the population, Icelanders are currently exceptionally well suited for ...

While we all aspire for a long lifespan, what is most coveted is a long period of vigor and health, or “healthspan,” that precedes the inevitable decline of advancing age. Researchers at UC Santa Barbara have discovered that instruments of death that cells use to commit suicide when things go wrong contribute to making a longer and healthier life by revitalizing the specialized cellular compartments called mitochondria. Mitochondria generate the energy for all of our activities, from movement to thought. These power plants inside our cells descended ...

Transistors — the tiny on-off switches inside microchips — have gotten smaller and smaller over the years, increasing computing power and enabling smaller devices. During that time, the copper wires that connect these switches have likewise shrunk. However, smaller, thinner wires create a big problem, said Daniel Gall, professor of materials science and engineering at Rensselaer Polytechnic Institute. “The job of the wire is to conduct electrons — electricity. Imagine a wire as a crowded hallway that the electrons have to get through. The narrower the hallway, the more the electrons bump into things and scatter. We call that resistance,” Gall ...

URBANA, Ill. — Waterhemp, the aggressive weed threatening Corn Belt crop production, is throwing curveballs once again, according to researchers at the University of Illinois Urbana-Champaign. The weed has famously developed resistance to not one or two, but seven herbicide sites-of-action classes, nearly exhausting the chemical tools farmers can use to defend their livelihood. In a new Weed Science study, U. of I. researchers show that a single major gene is responsible for waterhemp’s resistance to S-metolachlor ...

Scientists using NASA’s James Webb Space Telescope just made a breakthrough discovery in revealing how planets are made. By observing water vapor in protoplanetary disks, Webb confirmed a physical process involving the drifting of ice-coated solids from the outer regions of the disk into the rocky-planet zone. Theories have long proposed that icy pebbles forming in the cold, outer regions of protoplanetary disks — the same area where comets originate in our solar system — should be the fundamental seeds of planet formation. The main requirement of these theories is that pebbles should drift inward toward the star due to friction in the gaseous disk, ...
