| How a racing heart may alter decision-making brain circuits Posted: 30 Aug 2021 11:02 AM PDT In an effort to understand how the internal state of the body influences the brain's decision-making processes, scientists analyzed the data from a previous study pre-clinical study. They found that two of the brain's decision-making centers contain neurons that may exclusively monitor the body's internal dynamics. Furthermore, a heightened state of arousal appeared to rewire one of the centers by turning some decision-making neurons into internal state monitors. |
| Posted: 30 Aug 2021 07:49 AM PDT Half of pregnant women who had a simple blood test to check their iron stores had low iron levels, and one in four had severe iron deficiency, according to a new article. But despite how common iron deficiency is, 40% of pregnant women in this large regional study never had their iron levels checked, and women of lower socioeconomic status were less likely to get tested. Researchers said the findings underscore the need to revisit clinical guidelines to ensure that ferritin testing, the standard measure of iron deficiency, is included as a routine part of maternal care and pregnancy health screenings. |
| How can I avoid heart disease or stroke? Posted: 30 Aug 2021 06:59 AM PDT As much as 90% of the risk of a heart attack, stroke, or peripheral arterial disease (PAD) can be explained by smoking, poor eating habits, lack of physical activity, abdominal obesity, high blood pressure, raised blood lipid levels, diabetes, psychosocial factors, or alcohol. These guidelines focus on atherosclerotic cardiovascular disease (CVD), which affects the arteries. As the inside of the arteries become clogged up by fatty deposits, they can no longer supply enough blood to the body. This process is the main cause of heart attacks, strokes, PAD and sudden death where arteries become completely blocked. The most important way to prevent these conditions is to adopt a healthy lifestyle throughout life, especially not smoking, and to treat risk factors. |
| Turning cameras off during virtual meetings can reduce fatigue Posted: 30 Aug 2021 06:22 AM PDT Feeling drained after a day of virtual meetings is worse for those who keep their cameras on throughout those meetings, according to new research. The study also shows the effects are often stronger for women and newer employees. |
| Want to play college sports? A wealthy family helps Posted: 30 Aug 2021 05:18 AM PDT It takes more than athletic talent to play varsity sports in college, at least for most young people, a new study suggests. Researchers found that U.S. high-school athletes were much more likely to play sports in college if they came from higher-income families with well-educated parents and attended wealthier schools. |
| Perceptions of supernatural beings reveal feelings about good and bad in humans Posted: 30 Aug 2021 05:18 AM PDT What transpires in comedies and cartoons when a character has a devil on one shoulder and an angel on the other is not far off from people's perceptions of the real world, finds a new study. |
| Eating walnuts daily lowered 'bad' cholesterol and may reduce cardiovascular disease risk Posted: 30 Aug 2021 05:18 AM PDT Healthy older adults who ate a handful of walnuts (about ½ cup) a day for two years modestly lowered their level of low-density lipoprotein or LDL cholesterol levels. Consuming walnuts daily also reduced the number of LDL particles, a predictor of cardiovascular disease risk. The study explored the effects of a walnut-enriched diet on overall cholesterol in elderly individuals from diverse geographical locations and spanning two years. |
| Light-to-moderate coffee drinking associated with health benefits Posted: 30 Aug 2021 04:56 AM PDT Up to three cups of coffee per day is associated with a lower risk of stroke and fatal heart disease, according to new research. |
| Science-backed tips for maximizing play time with kids Posted: 26 Aug 2021 06:50 AM PDT A new study explores the science-backed core pillars of learning and examples of play spaces that incorporate them, and the researchers give tips for parents to use them at home. |
| The brain's 'prediction machine' anticipates the future when listening to music Posted: 19 Aug 2021 04:50 PM PDT We live our lives in real time, watching events unfold moment by moment. To make better sense of the world, however, our brains automatically predict how some events will unfold moments into the future. New research explores the brain's 'prediction machine' capabilities by examining how we experience music. |
