As scientific discoveries increase exponentially, scientists are forced to acknowledge the ethical limitations of unchartered experimentation. Although there are numerous experiments that would yield unparalleled insight, such as electronically monitoring brain activity and altering Deoxyribonucleic Acid (DNA) to avoid diseases, researchers must avoid disrupting the natural activity of the human body for the purpose of experimentation.
Ethics in science are standards of conduct that relate to both morality and integrity, according to au.af.mil. The morality of an experiment is described as the “ethics of the topics and findings” and is based on the potential harm that either the research process or results may cause. Ethics are often an issue in the biomedical field or when humans or animals are involved in experimentation. 
Scientists are often drawn to the unethical side of biology because the experiments that fall into this category have the potential to defy scientific boundaries and lead to revolutionary discoveries, according to telegraph.co.uk. 
If scientists disregarded all ethical standards, then they would have the ability to potentially separate twins after birth, test chemicals on humans, remove brain cells from living organisms, use beams of light to control brain cell activity, and create a hybrid of a human and a chimpanzee. This research could lead to breakthroughs in developmental psychology, toxicology, the relationship between human experience and genes, functions of the cortex, and the origins of the human species respectively, according to telegraph.co.uk. Although all of these experiments would be performed at the expense of human subjects, the results could have the potential to improve human life in unprecedented ways.
