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.
Conditions in the body are controlled, to provide a constant internal environment. This is called homeostasis. The conditions that must be controlled include body temperature, water content, carbon dioxide level, and blood sugar level. Hormones are chemicals secreted by glands.
