A new way to examine stress and inflammation in the heart will help Parkinson's researchers test new therapies and explore an unappreciated way the disease puts people at risk of falls and hospitalization.
The ability to obtain new memories in adulthood may depend on neurogenesis -- the generation of new neurons in the hippocampus -- to clear out old memories that have been safely stored in the cortex, according to research in male rats published in JNeurosci.
A team of University of Iowa researchers built a web-based app called MapTrek. When synced with a Fitbit, MapTrek allows users to go on virtual walking tours of locations such as the Grand Canyon or Appalachian trail while competing against other users. A study showed MapTrek and Fitbit users averaged 2,200 more steps per day than a control group that used only Fitbits.
When a cell divides, its constituents are usually evenly distributed among the daughter cells. UZH researchers have now identified an enzyme that guarantees that cell constituents that are concentrated in organelles without a membrane are properly distributed. Their discovery opens up new opportunities for the treatment of cancer, neurodegenerative diseases, aging processes and viral infections.
A new study has shown that people who regularly eat oranges are less likely to develop macular degeneration than people who do not eat oranges. Researchers at the Westmead Institute for Medical Research interviewed more than 2,000 Australian adults aged over 50 and followed them over a 15-year period.
A new commentary by scientists at the Universities of Manchester and Edinburgh on a study by Taiwanese epidemiologists supports the viability of a potential way to reduce the risk of Alzheimer's disease.
A study has newly identified an immune trigger of some fibrotic diseases and an experimental compound to treat it. Fibrosis -- a progressive scarring and hardening of internal organs -- is estimated to cause 35 to 40 percent of deaths in the world.
UCLA researchers have found that the PGC-1α gene, previously known to control human metabolism, also controls the equilibrium of bone and fat in bone marrow and also how an adult stem cell expresses its final cell type. The findings could lead to a better understanding of the disruption of bone-to-fat ratio in bone marrow and its health consequences, and point to the gene as a therapeutic target in the treatment of osteoporosis and skeletal aging.
A recent study in NeuroImage demonstrates that exercise performed immediately after practicing a new motor skill improves its long-term retention. More specifically, the research shows, for the first time, that as little as a single fifteen-minute bout of cardiovascular exercise increases brain connectivity and efficiency. It's a discovery that could, in principle, accelerate recovery of motor skills in patients who have suffered a stroke or who face mobility problems following an injury.
Contact with greenspace is known to have beneficial effects for mental health. A new study by the Barcelona Institute for Global Health (ISGlobal) suggests that it may also play a positive role against cognitive decline in elderly. In particular, this research published in Environmental Health Perspectives shows that the loss in cognitive functions expected as part of the aging process is slightly slower in people who live in greener neighborhoods.
