Oxygen is necessary for animal life, a truism that is so ingrained in experience and knowledge that few people stop to consider that many animals can go for significantly long periods of time without taking in oxygen. The freshwater turtle is a wonderful example of this adaptive physiology; it overwinters at the bottoms of lakes, and, to do so goes into a state of hibernation that allows it to live at the bottom of the lake without taking in additional oxygen for long periods of time. Scientists believe that two main physiological adaptations enable the turtles to engage in this behavior. First, the turtles' bodies depress their metabolic and cellular processes, which reduces their need for oxygen consumption. However, dealing with the need for oxygen only solves half of the hibernation dilemma; animals also build up lactic acid and this build up can be fatal. Therefore, it is important to understand how . Second, both the turtle's shell and its skeleton function as lactic-acid neutralizes. Between these two processes, turtles can overwinter underwater at just over freezing temperatures, with no oxygen, and extremely high circulating lactate levels for periods of up to four months. This paper investigates those processes and discusses possible applications for humans dealing with anoxia.

What is it like to live with the terrible, constant knowledge of what is going to happen in the future? Is this power of premonition a gift or a curse? This dilemma is hardly a new premise for a work of science fiction…

Face recognition is basic to daily survival. It is also a complicated process capable of error. Memory is central to the very process. Without an accurate recall of facial features, the retrieval process is useless. Brain scientists constantly explore to understand the process and its mechanisms better. The brain processes face information differently from those of objects. Encoding and the retrieval process and certain brain structures are essential to more reliable face recognition results.
