 This week's list of studies boast a wide range of topics including links between our nerves and food intake, links between milk consumption and cholesterol levels or how game-based physical activities help diabetes patients. Check out the highlights:
Same nerve cell -- Different influence on food intake The nerve cells, also called neurons, in our brain control all the basic processes of our body. For this reason, there are different types of neurons distributed over specific regions of the brain. Researchers have now developed an approach that allows them to show that neurons that are supposedly the same are actually very different: they not only sense different hormones for the body's energy state, but also have a different influence on food intake. This can have a direct effect on our metabolism, for example by differentially restraining our appetite.

The benefits of more daily steps occurred with both uninterrupted bouts of steps (10 minutes or longer) and short spurts such as climbing stairs.

Their findings provide new insights into the signals and mechanisms by which satiety is controlled and may have implications for treating obesity.

People who carry a certain variant of a gene that is key to this mechanism show improved jumping performance.

The decrease in their brain volumes with age is 70% slower than in Western populations.

The 8-week treatment program included diet, sleep, exercise and relaxation guidance, and supplemental probiotics and phytonutrients.
