The human respiratory system cares for gas exchange. The respiratory surface is internalized as linings of the lungs. Gas exchange in the lungs occurs in millions of small air sacs called alveoli. These microscopic air sacs have a very rich blood supply, thus bringing the air into close contact with the blood. Air has to …

The nuclear receptor Rev-erbα controls circadian thermogenic plasticity. Gerhart-Hines Z, et al. Nature. 2013. Nature. 2013 Nov 21;503(7476):410-413. doi: 10.1038/nature12642. Epub 2013 Oct 27. Abstract Circadian oscillation of body temperature is a basic, evolutionarily conserved feature of mammalian biology. In addition, homeostatic pathways allow organisms to protect their core temperatures in response to cold exposure. …
radio frequency identification Radio frequencies are used to read information from a “tag” that can be either “passive” or “active”. A passive tag has no power source while an active tag is supplied with power, usually from a small battery. The method used to communicate with the tags is referred to as “Near Field Communication” (NFC).
