Study finds olfaction plays a significant role in the motivation to exercise. Mice who were "high runners" developed genetic differences in their olfactory systems that caused them to perceive smells differently than more sedentary mice. Read More
For older adults, some sedentariness may not be as bad for memory as believed, especially if physical activity benchmarks are being met. Read More
Older adults who took brief, weekly "awe walks" for eight weeks reported improvements in positive emotions and a decrease in daily life stress. Read More
Aerobic exercise for up to one hour at moderate to high intensity improves memory, attention, and learning for up to two hours. Read More
Exercise increases levels of galanin in the brain stem, making mice more resilient to stress. Read More
Middle-aged women who scored high on extraversion personality traits were more likely to report being physically active during leisure time than those who scored high in neuroticism. Read More
The enzyme PHD3 plays a critical role in sensing nutrient availability and regulating the ability of muscles to break down fat. Blocking PHD3 production in mice leads to dramatic improvements in specific measures of fitness. Findings shed light on the key mechanism for how cells metabolize fuel and provide a novel understanding of muscle function and fitness. Read More
Study in rats reveals sex differences may play a key role in the effectiveness of exercise as an appetite regulator. Exercising female rats ate more than those who did not partake in physical activity. The same effect was not seen in males. Read More
Multiple sclerosis patients are nine times more likely to discuss the use of alternative medicines, including cannabis, with their neurologists as treatment options than they were in 2001. 81% of MS patients report the use of dietary supplements to help with disease management, and 39% report participating in mindfulness and other mind-body therapies. 30% of patients reported using marijuana to help treat their symptoms.

Regular exercise reduces the risk of developing obstructive sleep apnea, a new study reports. Adding twenty minutes to a daily walk, and increasing vigorous daily activities by eight minutes significantly lower sleep apnea risk. Read More
Following a one year program of aerobic exercise improves memory function and boosts blood flow to brain areas critical for cognition in older adults with risk factors for dementia. Read More
Six months of aerobic exercise intervention was associated with cognitive improvements and cerebrovascular regulation. Older people who embarked on the aerobic exercise program had, on average, a 5.7% improvement on tests of executive function and verbal fluency similar to that of a person five years younger.
