| Posted: 08 Apr 2022 05:38 AM PDT Researchers have developed a wearable device that plays specific sounds to enhance deep sleep. The first clinical study has now shown that the device is effective, but not at the same level of effectiveness for everyone. |
| Can artificial intelligence reveal why languages change over time? Posted: 07 Apr 2022 01:19 PM PDT American Sign Language (ASL) signs that are challenging to perceive -- those that are rare or have uncommon handshapes -- are made closer to the signer's face, where people often look during sign perception. By contrast, common ones, and those with more routine handshapes, are made further away from the face, in the perceiver's peripheral vision. The findings suggest that ASL has evolved to be easier for people to recognize signs. |
| Human gene variant produces attention deficit disorder-like problems in mice Posted: 07 Apr 2022 01:19 PM PDT Mutant mice are providing scientists with a new neurobiological framework to understand the brain changes observed in distractible humans who carry a common gene variant whose frequency has been associated with Attention Deficit Hyperactivity Disorder (ADHD). The scientists demonstrate that mice that express the variant adopt an inattentive phenotype similar to that seen in humans. |
| The role of genes in prenatal responses to air pollution Posted: 07 Apr 2022 11:19 AM PDT Exposure to pollution during pregnancy can have many adverse effects in infants and children that can even extend into adulthood. For example, air pollution exposure is associated with increased risk of low birth weight, preterm birth and risk for developing asthma later in life. Much of this is due to the fast pace of fetal growth and development; however, the exact ways pollutants have these effects and the roles of genes related to immune function and stress response are not fully understood. |
| Virtual cooking class improves children's nutrition knowledge Posted: 07 Apr 2022 07:10 AM PDT Amid parental concerns regarding poor nutrition and lack of cooking skills among youth in Flint, Michigan, a team of local dietitians, chefs, and researchers created Flint Families Cook during the COVID-19 pandemic, a program for families with children ages 8-18 years old, delivered virtually to children and families in their homes. |
| Selfies may drive plastic surgery by distorting facial features Posted: 06 Apr 2022 01:06 PM PDT Cellphone 'selfies' distort facial features, an effect that may be driving an uptick in requests for plastic surgery, researchers show in a new study. The findings highlight an unexpected consequence of social media and the need for plastic surgeons to discuss this phenomenon with their patients. |
| Most U.S. dog owners don't follow FDA pet food handling guidelines, study finds Posted: 06 Apr 2022 01:05 PM PDT A new analysis suggests that most U.S. dog owners are unaware of -- and do not follow -- guidelines on safe pet food and dish handling from the Food and Drug Administration (FDA), but that better education and implementation of the guidelines could reduce contamination. |
| Reducing air pollution by changing the way we dry our laundry Posted: 06 Apr 2022 01:05 PM PDT A new study has revealed that tumble drying a load of laundry releases almost the same amount of potentially harmful microfibers into the air as those released down the drain during machine washing of the same load. |
| How to reduce loneliness: Meaningful activities can improve health, well-being Posted: 06 Apr 2022 10:24 AM PDT A new study demonstrated that engaging in meaningful, challenging activities during free time can reduce people's loneliness and increase their positive feelings. |
| The road to popularity can be paved with unpleasantness Posted: 06 Apr 2022 07:18 AM PDT A longitudinal study tested the novel hypothesis that aggressive and disruptive children engage in frequent conflicts with classmates to strengthen their position in the group and enhance their popularity. Results revealed that higher initial levels of peer-reported aggression and disruptiveness were associated with increases in peer-reported popularity over the course of a semester, particularly for children who reported frequent disagreements with peers. |
| Machine learning model could better measure baseball players' performance Posted: 06 Apr 2022 07:18 AM PDT Researchers have developed a machine learning model that could better measure baseball players' and teams' short- and long-term performance, compared to existing statistical analysis methods for the sport. Drawing on recent advances in natural language processing and computer vision, their approach would completely change, and could enhance, the way the state of a game and a player's impact on the game is measured. |
| Researchers find a new way to measure flying baseballs Posted: 06 Apr 2022 07:16 AM PDT A new laboratory method uses a high-accuracy ball delivery device and speed measurement system to provide better clues on exactly how high and far some of those baseballs will fly. |
| Giving increased during the pandemic in areas hit hardest by COVID-19 Posted: 04 Apr 2022 03:55 PM PDT Charitable giving increased in counties that experienced COVID-19-related deaths, a new study reveals. |
