A study of Japanese people living in Malaysia found that their exercise routines affected time spent sitting down and quality of life, including their mental health. This study was published in Gerontology and Geriatric Medicine on October 25.
The physical presence of trails has less impact on forest birds than how frequently the trails are used by people, finds the first study to disentangle the effect of forest trails from the presence of humans. This is also the case when trails have been used for decades, suggesting that forest birds do not get used to human activity. To minimize disturbance, people should avoid roaming from designated pathways.
A majority of older adults do not wish to discuss life expectancy when presented with a hypothetical scenario on the topic.
Access to a usual source of medical care is particularly important for older adults as they manage chronic medical conditions. According to a new national study, odds of losing a usual source of care are higher among older adults who have unmet transportation needs, who move to a new residence, or who report symptoms of depression.
In Japan, rural tourism has been promoted for some time, but has few visible long-term positive effects. Researchers centered at Kanazawa University studied rural inn households that use tourism to supplement their incomes. While tourism was found to have environmental and strong social benefits, economic impact was minor. Many proprietors are also aging and lack successors. To thrive long-term, rural tourism destinations need greater competitiveness and would benefit from policies strengthening farming and community building.
The first high quality ancient DNA data from Central and South America -- 49 individuals some as old as 11,000 years -- has revealed a major and previously unknown exchanges between populations. For the first time, researchers have archaeological and genetic evidence linking some of the oldest humans in Central America to the earliest known populations to arrive in the New World.
A new monitoring project involving UCLA researchers and partners aims to take 'fake sushi' off Los Angeles diners' plates. The Los Angeles Seafood Monitoring Project team -- which includes university researchers, students, sushi restaurants and government regulators -- is working to reduce sushi fraud and the mislabeling of fish.
Researchers from Case Western Reserve University School of Medicine have shown that a single 'cocktail' of three pill-based anti-parasite medications is significantly more effective at killing microscopic larval worms in people diagnosed with lymphatic filariasis, commonly known as elephantiasis, than other standard two-drug combinations previously used in the global effort to eliminate this infectious disease. A combination of all three drugs given simultaneously had never been tested until now.
The 4th edition of the Dutch Soil Animal Days saw 856 'citizen scientists' comb through more than 200 gardens and parks to find some 7,500 soil creatures. Findings that stand out after this year's long, dry summer: woodlice have regained their ubiquitous status, while slugs were spotted in fewer places. The drought may also explain why so many people had difficulties finding all the soil animals, although having a balanced garden does help.
DNA analyses show that ancient populations of the Peruvian highlands adapted to the introduction of agriculture and an extreme, high-altitude environment in ways distinct from other global populations.
