| How people respond to wildfire smoke Posted: 30 Aug 2021 12:29 PM PDT Interviews with Northern California residents reveal that social norms and social support are essential for understanding protective health behaviors during wildfire smoke events -- information that could be leveraged to improve public health outcomes. |
| 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. |
| At least 80% of opioid overdoses aren’t fatal, but how do they affect the brain? Posted: 30 Aug 2021 09:32 AM PDT Scientists still know little about how opioid overdoses affect the brain and cognition. Researchers found that, while evidence exists to support a link between overdose, cognitive impairment and brain abnormalities, more research is needed in this area. |
| Low-sodium salt prevents stroke Posted: 30 Aug 2021 08:33 AM PDT Replacing salt with a low-sodium alternative lowers the risk of stroke in people with high blood pressure or prior stroke, according to recent research. |
| Integrated treatment for depression and heart failure improves quality of life and mood Posted: 30 Aug 2021 08:33 AM PDT Results suggest that simple measures, such as depression care administered by phone, can make a big difference for patients recovering from heart failure. |
| Unease beyond the uncanny valley: How people react to the same faces Posted: 30 Aug 2021 07:49 AM PDT If humanoid robots with the same appearance are mass-produced and become commonplace, how will human beings react to them? In a series of six experiments, scientists examined peoples' reactions when presented with images of people with the same face. Their results reveal a new phenomenon they call the clone devaluation effect -- a greater eeriness associated with cloned faces than with different faces. |
| Increased survival with eye melanoma in clinical trial Posted: 30 Aug 2021 07:00 AM PDT Once it has spread (metastasized), uveal (intraocular or eye) melanoma -- an unusual form of cancer -- has a very high mortality rate. Researchers and doctors show that, in a small group of patients with metastatic uveal melanoma, a new combination treatment can bring about tumor shrinkage and prolonged survival. |
| 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. |
| Insights into how a stroke affects reading could help with rehabilitation Posted: 30 Aug 2021 05:18 AM PDT Researchers, looking at the ability of people to sound out words after a stroke, found that knowing which region of the brain was impacted by the stroke could have important implications for helping target rehabilitation efforts. |
| 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. |
| Posted: 29 Aug 2021 05:19 AM PDT The first large-scale, long-term trial of a new strategy using combinations of very low-doses in one capsule, has demonstrated significantly improved control of high blood pressure -- the leading cause of heart attack and stroke. |
| Brain tissue inflammation is key to Alzheimer's disease progression Posted: 26 Aug 2021 08:17 AM PDT Neuroinflammation is the key driver of the spread of pathologically misfolded proteins in the brain and causes cognitive impairment in patients with Alzheimer's disease, researchers reveal in a new article. |
| 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. |
