zinc is found in virtually all of the body's - trillion cells and plays an important role in over enzyme systems in the human body. along with its companion nutrients, such as magnesium and b-vitamins, it is required for healthy cell division and the formation of new cells. it's also an important antioxidant...
the controversy surrounding embryonic stem cells. whether or not you feel there are moral implications in the use of stem cells isn't that important. allowing the scientists to do their job without the political battles, religious leaders butting in, and people weighing in on all the issues except the...

odor reception . [ ] of the genes that code for odor receptors, only a portion are functional. humans have far fewer active odor receptor genes than other primates and other mammals. [ ] in mammals, each olfactory receptor neuron expresses only one functional odor receptor. [ ] odor receptor nerve cells...

how natural hearing works: . ear canal: sound moves through the ear canal and strikes the eardrum. . eardrum and bones: sound waves cause the eardrum to vibrate, sending the bones in the middle ear into motion. . inner ear: this motion causes the fluid inside the inner ear (cochlea) to move the hair cells...

in the meat called stone cells. although modern varieties have fewer of these stone cells, all varieties still contain them. picking the pears before they have matured and holding them under cool controlled conditions prevents the formation of too many stone cells, and results in a less gritty pear!...
