Brown fat helps us release heat when we are cold. Recent research suggests that the absence of brown fat in adults may be linked to:

Urine is confined to the human bladder in part due to the structure of junctions that connect the cells lining the bladder. These junctions form a barrier that prevents the urine from leaking out into the extracellular space. What is the likely identity of these junctions?
