| Firefighter exposure to wildfire smoke compounds varies, depending on duties Posted: 08 Sep 2021 03:06 PM PDT Every summer, wildfires rage across the western U.S., and wildland firefighters are tasked with putting them out. But in the process, they inhale smoke and all the compounds in it, which can be harmful at high amounts. Now, researchers have evaluated the presence of particulate matter and volatile organic compounds (VOCs) around firefighters actively combating blazes, finding the highest exposures among hotshot crews and those creating firebreaks. |
| What the brain shows: The benefits of virtual reality in creative arts therapies Posted: 08 Sep 2021 03:05 PM PDT Researchers examined the differences in prefrontal cortex (PFC) activation between two distinct drawing tasks in virtual reality. Results of the study indicated significant differences between a rote tracing task and a creative self-expression task, with the rote tracing task showing an increase in PFC activity. It also showed there was reduced PFC activation for creative self-expressive tasks, indicating a possible relaxation response. |
| People with Parkinson's may benefit from seven walking strategies Posted: 08 Sep 2021 03:05 PM PDT Various strategies can help people with Parkinson's who have difficulty walking, but a new study finds that many people have never heard of or tried these strategies. The study also found that how well different compensation strategies worked depended on the context in which they were used, such as indoors versus outdoors, under time pressure or not. |
| No serious COVID-19 vaccine side effects in breastfeeding moms, infants, study finds Posted: 08 Sep 2021 03:05 PM PDT Researchers found that breastfeeding mothers who received either the Pfizer-BioNTech or Moderna vaccination reported the same local or systemic symptoms as what has been previously reported in non-breastfeeding women, with no serious side effects in the breastfed infants. |
| Forest fires linked to tens of thousands of avoidable deaths Posted: 08 Sep 2021 03:05 PM PDT Setting fire to forest and agricultural land in Southeast Asia to prepare it for cultivation or grazing causes air pollution that is contributing to an estimated 59,000 premature deaths a year, according to a new study. |
| Good sleep-time recovery is associated with a healthier diet and lower alcohol consumption Posted: 08 Sep 2021 03:04 PM PDT Good sleep-time recovery is associated with a health-promoting diet and health-promoting eating habits, as well as with lower consumption of alcohol, according to a new study investigating psychological and physiological well-being among working-age Finnish adults. |
| New information on the early stages of dementia with Lewy bodies Posted: 08 Sep 2021 03:04 PM PDT Results from a new study reinforce the notion that dementia with Lewy bodies can be pathologically classified into two different disease types. |
| Impaired immune response may cause bone resorption in patients with genetic disorder Posted: 08 Sep 2021 03:04 PM PDT Researchers have determined that enhanced bone resorption activity due to a faulty immune response may underpin multifocal osteomyelitis -- painful, chronic bone infections -- in children with MSMD, a rare genetic condition resulting from a range of immune system mutations. |
| Zoning policies that boost affordable housing: Good for the heart? Posted: 08 Sep 2021 03:04 PM PDT Inclusionary zoning policies that increase the supply of affordable housing may be good for the heart, according to new research.
