To better understand the link between the astronomical theory and the long ages assigned to the ice cores, it is necessary to discuss a topic that on the surface appears to have no connection whatsoever to the dating of ice cores: the chemistry of seafloor sediments.
A team of researchers led by Associate Professor Maria Kozhevnikov from the Department of Psychology at the National University of Singapore (NUS) Faculty of Arts and Social Sciences showed, for the first time, that it is possible for core body temperature to be controlled by the brain.
The part of the brain that acts as the body's thermostat is the hypothalamus which is the part of the brain that tells the body what it needs to do to survive and reproduce. The hypothalamus receives signals from all over the body regarding temperature.herefore, a stable body temperature of 98.6 degress Fahrenheit, give or take only a few degrees, is one aspect of homeostasis in humans. The main advantage of having a stable body temperature is that it allows optimization of normal body functions, metabolism and enzymes to a specific set temperature.
