| Resistance exercise may be superior to aerobic exercise for getting better ZZZs Posted: 03 Mar 2022 06:58 PM PST A new study found that resistance exercise may be superior to aerobic exercise as a way to get better sleep. A year-long resistance exercise program improved sleep quality, duration and other indicators of a good night's sleep more so than aerobic exercise, combined aerobic and resistance exercise, and no exercise. Researchers say interventions focused on resistance exercises may be a way to improve sleep and, in turn, cardiovascular health. |
| New species of stegosaur is oldest discovered in Asia, and possibly the world Posted: 03 Mar 2022 06:58 PM PST Relatively small, but fearsome-looking stegosaur measured about 2.8 meters (9 feet) from nose to tail -- but scientists can't tell whether the remains are those of an adult or juvenile. |
| Researchers identify potential approaches to modify the vaginal microbiome Posted: 03 Mar 2022 04:15 PM PST Study shows that L. iners has unique nutritional requirements that distinguish it from L. crispatus, potentially allowing it to be targeted using novel therapeutic strategies. |

| Scooting to a new era in active transportation Posted: 03 Mar 2022 04:14 PM PST In recent years, shared electric scooters (e-scooters) have taken cities by storm. But how are people using this new mode of transportation? A new study has some interesting data to share on e-scooter users. Self-reported safety behaviors didn't always match with observations: the reported use of helmets (13% while riding) far outweighed researchers' observations in Salt Lake City (2% of riders) or Tucson (2% of riders). |
| How triple-pane windows stop energy (and money) from flying out the window Posted: 03 Mar 2022 01:20 PM PST Next generation triple-pane windows provide builders with lower cost options and help homeowners conserve energy, reduce noise, and lower home energy bills. |
| Magnetic excitations could provide information transfer without heat loss Posted: 03 Mar 2022 01:20 PM PST Just as electrons flow through an electrical conductor, magnetic excitations can travel through certain materials. Such excitations, known in physics as 'magnons' in analogy to the electron, could transport information much more easily than electrical conductors. An international research team has now made an important discovery on the road to such components, which could be highly energy-efficient and considerably smaller. |

| Joro spiders likely to spread beyond Georgia, US Posted: 03 Mar 2022 11:41 AM PST The Joro spider first arrived stateside around 2013 and has since spread across the state and Southeast. But new research suggests the invasive arachnids could spread through most of the Eastern Seaboard of the U.S. |
| Communication defect in psychotic disorders Posted: 03 Mar 2022 11:12 AM PST Communication between brain areas is crucial for the brain to correctly process sensory signals and adopt an appropriate behavioural response. Yet, dysfunctions in these communication pathways could be strongly correlated with the onset of schizophrenia. For the first time, a team has succeeded in demonstrating this phenomenon in human beings. By carrying out analyses of the brain activity of children, adolescents and young adults with a genetic risk of the disease, the research team has demonstrated that a reduction in the activation of gamma waves, that are known for their role in the proper transmission of information in the brain, was correlated with the emergence of psychotic symptoms even before full-blown disorders appear. |
| Rapid evolution fuels transcriptional plasticity in fish species to cope with ocean acidification Posted: 03 Mar 2022 11:12 AM PST A research team has revealed the basis to variability across different fish species and uncovered that some species evolve more rapidly, providing them with evolved molecular toolkits and allowing them able to cope with future ocean acidification. |
| Energy-harvesting wearable device made from recycled waste Posted: 03 Mar 2022 11:12 AM PST Wearable devices could soon be entirely made of recycled waste materials -- and powered by human movement, thanks to a new energy-harvesting device. |
| Two-faced orchestrator: Tis gene regulates positive and negative immune responses in plants Posted: 03 Mar 2022 11:12 AM PST The mechanism of plant defense mediated by the non-expressor of pathogenesis-related (NPR) genes in monocots (plants having a single embryonic leaf) is not well-documented. Now, scientists have discovered how the NPR family of genes regulate immune responses in the model monocot Brachypodium distachyon. These findings provide a blueprint for plants' defense systems and might contribute to more research towards resilient crop species, boosting pesticide-free cereal crop cultivation. |
| Physics race pits Usain Bolt against Jurassic Park dinosaur Posted: 03 Mar 2022 11:12 AM PST Scott Lee is a physics professor at the University of Toledo who has developed numerous learning activities to help intro-level students get enthusiastic about the topic. His latest innovative activity poses the question: Is Usain Bolt faster than a 900-pound dinosaur? |
| Seeing is believing when it comes to health risk and behavior change Posted: 03 Mar 2022 11:11 AM PST Using medical imaging technologies that can visualize health may discourage risk-related behaviors more than non-visual information. A new meta-analysis finds that when individuals undergo an imaging procedure and are shown visual personalized information about their own risk of disease, they may be more likely to reduce risky behaviors. |
| Lipid profiling can predict risk of diabetes, cardiovascular disease decades before onset Posted: 03 Mar 2022 11:11 AM PST Simultaneous measurement of dozens of types of fats in the blood ('lipidomics') can predict the risk of developing type 2 diabetes (T2D) and cardiovascular disease (CVD) years in the future, according to a new study. Such early prediction through lipidomic profiling may provide the basis for recommending diet and lifestyle interventions before disease develops. |
| Posted: 03 Mar 2022 11:11 AM PST Researchers have characterized brain activity that occurs when we are socially influenced to change our minds. The study shows how the brain distinguishes between different types of social conformity when revising one's opinions. |
| Working, studying in 'off' hours can harm motivation Posted: 03 Mar 2022 09:50 AM PST Working a nontraditional schedule, and checking in at all hours of the day, night and weekends, is not necessarily beneficial for the 21st-century workforce, according to new research. |

| Time off after high school makes college less likely Posted: 03 Mar 2022 09:50 AM PST Academic breaks after high school -- even those lasting just a few months -- can cause some students, especially those from disadvantaged backgrounds, to forgo enrolling in college altogether, according to new research. |
| New tool reveals function of enigmatic gene sequences Posted: 03 Mar 2022 09:08 AM PST While the large proportion of our genome that does not instruct our cells to form proteins has been harder to study than protein-coding genes, it has been shown to have vital physiological functions. Scientists have now developed new high-precision tools able to identify what these noncoding sequences do. The study may eventually contribute to the development of new, targeted drugs. |
| Attention! Brain scans can tell if you are paying it Posted: 03 Mar 2022 08:22 AM PST Using a model of fMRI data collected from 92 individuals performing several types of attention-related tasks, researchers successfully predicted how well those individuals would perform on the tasks based on their brain scans alone. This generalized model can also predict severity of an individual case of attention deficit and hyperactivity disorder. The study was published March 3 in the journal Nature Human Behavior. |

| Weighing up: What’s the bottom line when it comes to weight loss? Posted: 03 Mar 2022 08:22 AM PST When it comes to weight loss, many of us have dabbled in the latest diets. But whether you're cutting carbs or keeping to keto, new research shows that diet trends can cost more than your waistline and leave a hefty hole in your hip pocket. |
| Posted: 03 Mar 2022 08:22 AM PST Researchers develop tool that 'audits' the results of studies that examine interplay between variables. Using this approach, researchers identify inconsistent findings in one-third of previous association studies of gut microbiome and disease. The software can help researchers check the reliability of their own findings before submitting them for publication. Association studies are critical in paving the way to further research into disease causes and mechanisms of dysfunction. |
