Lack of Exercise Not to Blame
"Scientists have questioned the assumption that a lack of exercise causes fatness in children. The study suggests that physical inactivity appears to be the result of fatness, instead of its cause."
"Scientists have questioned the assumption that a lack of exercise causes fatness in children.
The study suggests that physical inactivity appears to be the result of fatness, instead of its cause. Researchers said the findings indicate that nutrition, rather than exercise, is the best way of tackling childhood obesity," reports The Independent. "The EarlyBird team followed more than 200 children in Plymouth over three years, monitoring their fat and exercise levels at regular intervals. They found that body fat levels had an effect on physical activity, but that varying activity did not lead to any changes in fatness. The paper, published in the Archives of Disease in Childhood, suggests that overweight children may think about their body negatively, shying away from sports and exercise as a result."
It's a development that could one day lead to much better treatments for osteoporosis, joint damage, and bone fractures.
- Scientists have isolated skeletal stem cells in adult and fetal bones for the first time.
- These cells could one day help treat damaged bone and cartilage.
- The team was able to grow skeletal stem cells from cells found within liposuctioned fat.
Gut bacteria play an important role in how you feel and think and how well your body fights off disease. New research shows that exercise can give your gut bacteria a boost.
- Two studies from the University of Illinois show that gut bacteria can be changed by exercise alone.
- Our understanding of how gut bacteria impacts our overall health is an emerging field, and this research sheds light on the many different ways exercise affects your body.
- Exercising to improve your gut bacteria will prevent diseases and encourage brain health.
A groundbreaking new study shows that octopuses seemed to exhibit uncharacteristically social behavior when given MDMA, the psychedelic drug commonly known as ecstasy.
- Octopuses, like humans, have genes that seem to code for serotonin transporters.
- Scientists gave MDMA to octopuses to see whether those genes translated into a binding site for serotonin, which regulates emotions and behavior in humans
- Octopuses, which are typically asocial creatures, seem to get friendlier while on MDMA, suggesting humans have more in common with the strange invertebrates than previously thought
