| Gamification, past habits may impact future eco-friendly tendencies differently Posted: 10 Mar 2022 02:08 PM PST Green consumer habits may not be impacted by gamification practices, but people who purchased environmentally friendly products in the past are likely to continue to do so, according to a team of researchers, who theorized that adding gamification techniques to a consumer's eco-friendly purchasing habits would perpetuate green consumerism. |
| Prenatal mindfulness program improves stress response in infants Posted: 10 Mar 2022 11:37 AM PST Infants whose mothers participated in a mindfulness-based program during pregnancy had healthier stress responses at 6 months old, a new study found. |
| Damage to inner ear system predicts fall risk among people with Alzheimer's disease Posted: 10 Mar 2022 11:37 AM PST A study of about 50 people with Alzheimer's disease has added to evidence that damage to the inner ear system that controls balance is a major factor in patients' well-documented higher risk of falling. |
| Blood test as possible diagnostic tool for Alzheimer’s disease Posted: 10 Mar 2022 08:50 AM PST A recent study shows promising results for a blood test that could be used to identify Alzheimer's changes in the brain before the onset of any symptoms, which could result in preventative treatments being used before any memory loss. |
| Could leaky blood vessels in the brain be a culprit in Alzheimer’s disease? Posted: 10 Mar 2022 08:50 AM PST Researchers report that they found high levels of the protein Fli-1 in the brains of deceased Alzheimer's patients. Blocking Fli-1's action in a mouse model of Alzheimer's disease reversed mental loss and reduced the brain inflammation and amyloid-beta clumping that are hallmarks of Alzheimer's disease. Although clinical translation of this finding is likely years off, the study suggests Fli-1 is a promising therapeutic target for Alzheimer's disease. |
| Robot that seems to convey emotion while reading Posted: 10 Mar 2022 07:00 AM PST Researchers have created a robot with an internal weight that can give the impression of conveying emotions while reading text messages. It can also remind users to not get upset, which may help them cope with unpleasant information. |
| Video game-based therapy helps stroke patients Posted: 09 Mar 2022 01:55 PM PST After a stroke, patients may lose feeling in an arm or experience weakness and reduced movement that limits their ability to complete basic daily activities. Traditional rehabilitation therapy is very intensive, time-consuming and can be both expensive and inconvenient, especially for rural patients travelling long distances to in-person therapy appointments. That's why a team of researchers utilized a motion-sensor video game, Recovery Rapids, to allow patients recovering from a stroke to improve their motor skills and affected arm movements at home while checking in periodically with a therapist via telehealth. |
| Childhood trauma and genetics linked to increased obesity risk Posted: 09 Mar 2022 11:09 AM PST New research has found associations between genetics, obesity, and childhood trauma, linking social health determinants, genetics, and disease. The study found that participants with specific genetic traits and who experience childhood traumas are more likely to suffer from adult obesity. |
| Hugging a 'breathing' cushion to ease anxiety Posted: 09 Mar 2022 11:09 AM PST Researchers have developed a huggable, cushion-like device that mechanically simulates breathing, and preliminary evidence suggests it could help reduce students' pre-test anxiety. |
| Music combined with auditory beat stimulation may reduce anxiety for some Posted: 09 Mar 2022 11:09 AM PST Treatments integrating music and auditory beat stimulation are effective in reducing state anxiety in some patients, according to a new study. |
| Frequent external childcare can affect children's behavior, survey suggests Posted: 09 Mar 2022 11:09 AM PST A survey of around 1,300 Zurich school children, their parents and teachers suggests that the more time children spend in external daycare, the more likely they are to exhibit problematic behavior. However, this behavior generally disappears at the end of primary school. |
| Study hints at how early life experiences may affect brain wiring Posted: 09 Mar 2022 11:08 AM PST A new study of brain development in mice shortly after birth may provide insights into how early life events can affect wiring patterns in the brain that manifest as disease later in life. |
| Reducing subsequent injuries after a concussion Posted: 09 Mar 2022 10:18 AM PST Looking for techniques to keep young athletes safer post-concussion, researchers devised a study in which teenage athletes who suffered concussions were randomized either to standard of care -- typically returning to play after clearing a set of standardized protocols that assess symptoms, cognition, and balance -- or completing the same protocol and then working with an athletic trainer on a specific neuromuscular training intervention that includes guided strength exercises and a focus on posture and landing stability. |
| Sleep apnea accelerates aging, but treatment may reverse it Posted: 09 Mar 2022 10:18 AM PST Obstructive sleep apnea (OSA) affects 22 million people in the U.S. and is linked to a higher risk of hypertension, heart attacks, stroke, diabetes and many other chronic conditions. But now researchers have found that untreated OSA also accelerates the biological aging process and that appropriate treatment can slow or possibly reverse the trend. |
| New technology enables unprecedented glimpse inside single brain cells Posted: 09 Mar 2022 10:18 AM PST Researchers have developed a new genomic technology to simultaneously analyze the DNA, RNA and chromatin -- a combination of DNA and protein -- from a single cell. The method, which took five years to develop, is an important step forward for large collaborations where multiple teams are working simultaneously to classify thousands of new cell types. The new technology will help streamline analyses. |
| Sharing memories sets children on path to better well-being Posted: 09 Mar 2022 07:45 AM PST Toddlers whose mothers received special coaching in talking about memories grew into teenagers who experience better wellbeing, research shows. |
| Patients with persistent postural-perceptual dizziness show warning signs early on Posted: 09 Mar 2022 07:45 AM PST People who suffer from persistent postural-perceptual dizziness (PPPD) experience unsteadiness, non-spinning vertigo and dizziness. These symptoms are exacerbated by movement, upright posture, and visual stimuli. In a new study, scientists have tried to find out if these exacerbating factors are present in the period before PPPD is diagnosed. They found that patients developing PPPD are likely to have them early on after the onset of balance disorder symptoms. |
| Mindfulness-based cognitive therapy benefits people with depression through promoting self-kindness Posted: 09 Mar 2022 07:44 AM PST New research shows that Mindfulness-Based Cognitive Therapy (MBCT) can help promote self-kindness in people with a history of depression, thereby putting their bodies in a state of safety and relaxation. |
| Posted: 09 Mar 2022 06:08 AM PST A preclinical study led by a neuroscientist shows that dysregulated kappa-opioid receptors (KORs) in the brain's medial prefrontal cortex region (part of the frontal lobe) contribute to working memory deficits in severe alcohol dependence. The researchers discovered that an antagonist compound used to block KORs alleviated these working memory deficits and may help restore 'normal' executive function needed to make better decisions about alcohol consumption. |
| People with serious mental illness may have increased heart disease risk at younger ages Posted: 09 Mar 2022 06:07 AM PST An analysis of nearly 600,000 adults in the U.S. found people with bipolar disorder, schizophrenia or schizoaffective disorder had up to double the estimated cardiovascular risk levels than those without such illnesses, even at younger ages. The study focused on adults diagnosed with one of those three serious mental illnesses, who were not hospitalized or living in a mental health treatment center and estimated their 10-year and 30-year cardiovascular risk. Earlier identification and management of major cardiovascular risk factors -- including obesity, smoking, diabetes and high blood pressure -- in young adults with a serious mental illness may reduce risk of heart disease and improve outcomes, researchers said. |
| Some of the world’s lowest rates of dementia found in Amazonian indigenous groups Posted: 09 Mar 2022 06:07 AM PST A new study reveals that two indigenous groups in the Bolivian Amazon have among the lowest rates of dementia in the world. An international team of researchers found among older Tsimane and Moseten people, only about 1% suffer from dementia. In contrast, 11% of people age 65 and older living in the United States have dementia, according to the Alzheimer's Association. |
| Skin cancer cells use Alzheimer’s protein to sabotage brain's immune defenses Posted: 09 Mar 2022 06:06 AM PST Amyloid beta, a protein known to build-up in the brains of Alzheimer's patients, also helps skin cancer cells thrive when they spread to the brain, a new study finds. |
| Preparing for when lightning strikes the same place twice, then strikes again Posted: 08 Mar 2022 12:56 PM PST Disasters such as hurricanes, wildfires, floods, tornadoes, and droughts are not only increasing in intensity and frequency, they are also striking the same place multiple times. Yet, to date, disaster research largely focuses on individual events, and fails to account for legacy effects that leave people vulnerable in the wake of repeated disasters. To improve predictive capacity to better prepare for future disasters, an interdisciplinary team of researchers has developed a novel framework for improving scientific understanding of 'recurrent acute disasters' (RADs). Their work was published today in Science Advances. |
| Posted: 08 Mar 2022 07:27 AM PST One epigenetic factor, known as HDAC4, as well as one organic anion transporter (OAT1) contribute to the development of chronic pain. Using mouse models, researchers demonstrated that HDAC4 influences the expression of genes in neuronal cells involved in the processing of pain. The experiments also revealed that OAT1 regulates pain sensitivity in the spinal cord. |
