Not about visceral fat or subcutaneous fat, but more information about
brown fat.

For more than 30 years, scientists have been intrigued by brown fat, a
cell that acts like a furnace, consuming calories and generating heat.
Rodents, unable to shiver effectively to keep warm, use brown fat
instead. So do human infants, who do not shiver very well. But it was
generally believed that humans lose brown fat after infancy, no longer
needing it once the shivering response kicks in.

That belief, three groups of researchers report, is wrong.
