As a result, the body's physiological processes are no longer coordinated. The adrenal gland plays a key role in this process. When the...

Some die from starvation while others survive. Scientists have long believed that the difference between life and death for the iguana depended on the animals' ability to secrete the stress hormone corticosterone. Under stressful conditions, corticosterone functions like a spigot by controlling how the body expends...
