Newborn lambs' central heating system could aid fat busting in humans
...al white fat that stores surplus energy, brown fat generates heat in response to cold or excess caloric intake. While some mammals such as rodents maintain this 'good' fat throughout life, humans are similar to lambs: brown fat is present in the newborn to act as an internal central heating system maintaining ...New proteomics core at OHSU will speed discovery process
