Researchers develop artificial adrenal system in animal model

If the function of the adrenal gland is disturbed it does not produce enough stress-adjusting messengers. The results are serious and cause life-threatening diseases. Under the direction of Prof. Dr. Stefan R. Bornstein of the university hospital Carl Gustav Carus researchers developed an artificial adrenal system together with the medicine Nobel Prize Laureate Prof. Dr. Andrew Schally in an animal model.

Stockholm researchers discover new mechanism that stimulates glucose uptake in brown fat

Research findings that can likely be used to develop a new type of medicine for type 2 diabetes are published today in the Journal of Cell Biology. Researchers at Stockholm University have discovered a new mechanism that stimulates glucose uptake in brown fat - a tissue whose primary function is to generate heat by burning fat and sugar.

Engineered cells reveal changes associated with learning, memory and reward

Scientists have created cells with fluorescent dyes that change color in response to specific neurochemicals. By implanting these cells into living mammalian brains, they have shown how neurochemical signaling changes as a food reward drives learning, they report in Nature Methods online October 26.

Resistance exercise can improve episodic memory, shows study

Here's another reason why it's a good idea to hit the gym: it can improve memory. A new Georgia Institute of Technology study shows that an intense workout of as little as 20 minutes can enhance episodic memory, also known as long-term memory for previous events, by about 10 percent in healthy young adults.
