| Surveys with repetitive questions yield bad data, study finds Posted: 28 Jan 2022 12:35 PM PST Surveys that ask too many of the same type of question tire respondents and return unreliable data, according to a new study. The study found that people tire from questions that vary only slightly and tend to give similar answers to all questions as the survey progresses. Marketers, policymakers, and researchers who rely on long surveys to predict consumer or voter behavior will have more accurate data if they craft surveys designed to elicit reliable, original answers, the researchers suggest. |
| New genetic clues on multiple sclerosis risk Posted: 28 Jan 2022 11:13 AM PST An international team of researchers has discovered that a cell type in the central nervous system known as oligodendrocytes might have a different role in the development of multiple sclerosis (MS) than previously thought. The findings could open for new therapeutical approaches to MS. |
| Researchers discover new way to target secondary breast cancer that has spread to the brain Posted: 28 Jan 2022 07:07 AM PST A study has revealed a potential new way to treat secondary breast cancer that has spread to the brain, using existing drugs. |
| Can wearable technology predict the negative consequences of drinking? Posted: 27 Jan 2022 02:26 PM PST Researchers demonstrated how wearable sensors can augment researchers' understanding of when drinking will lead to negative consequences. The researchers measured intoxication with an ankle bracelet that can detect alcohol concentration from imperceptible amounts of sweat. |
| The effects of pediatric critical illness on absenteeism Posted: 27 Jan 2022 02:26 PM PST Children who survive critical illness and their parents commonly experience physical, emotional, and cognitive conditions as a result of the critical illness. These effects can also include prolonged absences from school and/or work. What has not been fully understood is the rate and duration of school absences among these children and work absences among their caregivers. |
| Zika vaccine shows promising results in preclinical studies Posted: 27 Jan 2022 02:26 PM PST A Zika virus vaccine candidate is effective at preventing the Zika virus passing from mother to fetus in preclinical animal studies, according to a new study. |
| Psychiatric disease associated with increased risk of death from cardiovascular disease and diabetes Posted: 27 Jan 2022 11:16 AM PST Among patients with chronic, non-communicable diseases, the risk of death is more than doubled if they also have a psychiatric comorbidity, according to a new study. |
| Why the human brain is more vulnerable to disease Posted: 27 Jan 2022 11:16 AM PST With the help of cerebral organoids, scientists were able to ascertain that tuberous sclerosis, a rare neurodevelopmental genetic disorder, arises developmentally rather than only genetically. With these patient-derived laboratory models of the human brain, they pinpointed the origin of the disease to progenitor cells specific to humans. The findings further show that the pathology of diseases affecting the human brain could only be well understood using human-derived brain organoid models. |
| 'Cell atlas' of brain vasculature connects stroke with novel immune cells Posted: 27 Jan 2022 11:15 AM PST In work that will enhance the study of such disparate diseases as stroke and dementia, researchers have catalogued all the cells that form the blood vessels of the human brain, along with their locations and the genes transcribed in each. |
| Another pandemic challenge for nurses: Sleep problems Posted: 27 Jan 2022 09:58 AM PST More than half of nurses had difficulty sleeping during the first six months of the COVID-19 pandemic -- and getting less sleep increased their odds of experiencing anxiety and depression, according to a new study. |
| A nudge to resume economic activity Posted: 27 Jan 2022 08:43 AM PST Researchers have found that people are more likely to partake in economic activity during the COVID-19 pandemic when they know their neighbors are engaged in the same activities. |
| Researchers identify osteoarthritis ‘pain pathway’ Posted: 27 Jan 2022 07:42 AM PST Researchers have discovered that a particular molecular signaling pathway plays an important role in producing osteoarthritis (OA) pain. Using a mouse model of painful osteoarthritis, they show that blocking this signaling pathway eliminates pain and results in a return to normal limb use. This work is the first to find an association between this pathway and OA pain, and could lead to the development of new, effective pain treatments for human OA sufferers. |
| Posted: 27 Jan 2022 07:42 AM PST Eating more meat, having less of certain bacteria in the gut, and more of certain immune cells in the blood, all link with multiple sclerosis, reports a team of researchers. The work teased out subtle connections that could lead to a better understanding of the causes of the disease. |
| New drug screening method answers why Alzheimer’s drugs fail, suggests new targets Posted: 27 Jan 2022 07:42 AM PST A new study sheds light on why Alzheimer's drugs so far have been ineffective at curing or reversing the disease. The researchers identify new targets for drug development and present a new method to screen drugs for treating Alzheimer's disease. |
| Even dim light before bedtime may disrupt a preschooler’s sleep Posted: 27 Jan 2022 07:42 AM PST A new study of preschoolers finds that exposure to even very low intensities of light before bedtime can sharply reduce production of the sleep-promoting hormone melatonin, interfering with sleep. It suggests that young children are highly susceptible to the physiological impacts of light at night and some kids are more sensitive than others. |
| Flavonoids may reduce mortality risk for people with Parkinson’s Disease Posted: 26 Jan 2022 01:55 PM PST People with Parkinson's Disease who eat more flavonoids -- compounds found in richly colored foods like berries, cocoa and red wine -- may have a lower mortality risk than those who don't, according to a new study. |
| Research reveals new links between brain over-activity and schizophrenia symptoms Posted: 26 Jan 2022 09:25 AM PST New research has shown that over-activity in a specific area of the brain is linked to certain symptoms of Schizophrenia, opening up possibilities for the development of more targeted treatments. |
| Unique weapon in immune system arsenal could unlock MS treatment Posted: 26 Jan 2022 06:05 AM PST Researchers have identified why certain cells in the body, known as Th17 cells, go rogue and promote the onset of autoimmune diseases such as multiple sclerosis (MS). |
| How we view the future may hold keys to recovery from alcohol use disorder Posted: 25 Jan 2022 08:26 AM PST Researchers suggest that modifying the time perspective of people with alcohol use disorder (AUD) may improve their recoveries. Alcohol use disorder creates an estimated economic burden of $249 billion every year with more than 15 million adults in the U.S. coping with alcohol use disorder. |
