Alexander Fleming's Discovery of Penicillin
Purpose: Initially to study Staphylococcus bacteria. Findings: Noticed that mold (Penicillium notatum) prevented bacterial growth, leading to the discovery of penicillin. Ethical considerations: Serendipitous discovery with no direct ethical implications at the time.
The Milgram Experiment
Purpose: To examine obedience to authority figures. Findings: A large number of participants were willing to administer what they believed to be painful electric shocks to another person when instructed by an authority figure. Ethical considerations: Deception of participants and the potential psychological harm raised serious ethical concerns.
Human Genome Project
Purpose: To map and sequence the DNA of the entire human genome. Findings: Completed the map of human genetic material, contributing to advances in medicine, biotechnology, and genetics. Ethical considerations: Raised concerns about genetic privacy and discrimination.
Hans Asperger's Studies on Autism
Purpose: To categorize children with distinct psychological behaviours. Findings: Described a form of autism now known as Asperger's Syndrome. Ethical considerations: During the Nazi era, his work has been scrutinized for possibly sending children to their deaths under the regime's euthanasia program.
Walter Reed's Yellow Fever Experiments
Purpose: To determine the transmission of yellow fever. Findings: Concluded that Aedes aegypti mosquitoes were responsible for spreading yellow fever. Ethical considerations: Involved human subjects in potentially dangerous experiments; however, participants gave informed consent.
Edward Jenner's Smallpox Vaccine Experiment
Purpose: To develop a vaccination method for smallpox. Findings: Successfully demonstrated immunity against smallpox using cowpox material. Ethical considerations: Involved risks by inoculating a healthy individual, James Phipps, with cowpox.
James Lind's Scurvy Experiment
Purpose: To identify a cure for scurvy. Findings: Found that oranges and lemons were effective in curing scurvy. Ethical considerations: Lack of control group, but relatively ethical for its time as treatments were provided to all groups of participants.
Project MKUltra
Purpose: A CIA program to research mind control and chemical interrogation techniques. Findings: Unconclusive results regarding effective mind control, but extensive documentation of human rights abuses. Ethical considerations: Highly unethical with its use of unknowing participants, administration of drugs, and various forms of torture.
Jonas Salk's Polio Vaccine Trials
Purpose: To test the effectiveness and safety of the polio vaccine. Findings: Demonstrated that the killed-virus vaccine was safe and effective in preventing polio. Ethical considerations: Involved risks associated with mass vaccination campaigns and public pressure for a vaccine.
Semmelweis's Hand Washing Experiment
Purpose: To prove that hand washing could drastically reduce the number of women dying after childbirth. Findings: Demonstrated that hand washing with chlorinated lime solutions could significantly decrease the incidence of puerperal fever deaths. Ethical considerations: There were minimal risks involved; however, the implications were not immediately accepted by the medical community.
The Belmont Report and its Role in Research Ethics
Purpose: To establish ethical principles and guidelines for research involving human subjects. Findings: Introduced respect for persons, beneficence, and justice as key ethical principles. Ethical considerations: The report itself is a foundational document in the ethics of clinical research, addressing issues raised by past unethical studies.
The Tuskegee Syphilis Study
Purpose: To observe the natural progression of untreated syphilis in African-American men. Findings: Documented the severe health issues caused by syphilis when not treated. Ethical considerations: Highly unethical as participants did not give informed consent, were misled, and were denied treatment.
HeLa Cells Research
Purpose: To use a line of human cells for medical research. Findings: HeLa cells were instrumental in various medical breakthroughs and are some of the most important cell lines in medical research. Ethical considerations: Raised issues about consent, as the cells were taken without Henrietta Lacks' knowledge or consent and her identity was initially not given recognition.
Henrietta Lacks and the HeLa Cell Line
Purpose: Henrietta Lacks' cancer cells were the first to be successfully cloned and were used to create an immortal cell line for medical research. Findings: HeLa cells were vital in developing the polio vaccine, understanding cancer, and much more. Ethical considerations: Raised ethical issues regarding consent as cells were taken without her or her family's knowledge or approval.
The Discovery of DNA Structure
Purpose: To determine the structure of DNA. Findings: James Watson and Francis Crick, building on the work of Rosalind Franklin and others, discovered the double helix structure of DNA. Ethical considerations: Posthumous recognition of Rosalind Franklin's contributions raises questions of gender equity in science.
Stanford Prison Experiment
Purpose: To investigate the psychological effects of perceived power, focusing on the struggle between prisoners and prison officers. Findings: Demonstrated that perfectly healthy individuals could display abusive behaviors in a prison-like environment. Ethical considerations: The experiment was stopped early due to extreme psychological stress and abusive behavior observed; it lacked full informed consent.
Pavlov's Classical Conditioning
Purpose: To study digestive processes in dogs. Findings: Established the principles of classical conditioning. Ethical considerations: Involves animal experimentation, which raises concerns about the treatment of the dogs used in his research.
Harlow's Monkey Studies
Purpose: To study the effects of maternal separation and social isolation on infant rhesus monkeys. Findings: Concluded that social isolation had a detrimental effect on the development of the monkeys. Ethical considerations: Considered highly unethical by modern standards due to the psychological distress inflicted on animals.
Thalidomide Tragedy
Purpose: Thalidomide was marketed as a mild sleeping pill safe even for pregnant women. Findings: Led to thousands of babies being born with phocomelia or other serious malformations. Ethical considerations: The disaster led to stricter drug regulations and testing before approval.
David Reimer's Case as John/Joan
Purpose: To support the theory that gender identity is primarily learned and can be changed with surgery and proper upbringing. Findings: The case was initially claimed to be a success but later revealed to be a failure, as David Reimer did not identify as female. Ethical considerations: Ethical breaches include lack of informed consent and psychological harm.
