Monell researchers find metabolic defect in liver that can lead to obesity
...is due to a reduced capacity to burn fat. Fat is one
of the fuels that the bodys cells burn to provide energy. This process, known as fat oxidation, takes place inside mitochondria, the cells power plants for generating energy. If the ability to oxidize fat is impaired, the bodys capacity to make ...
Radiation therapy combined with microsurgery shows promise for curing injured spinal cord

Bumblebees make bee line for gardens, National Bumblebee Nest Survey finds
...han 700 volunteers surveyed their own gardens plus one
