In the early 2000s researchers began developing microdevices referred to as organs-on-a-chip (OOCs), which use cell cultures to imitate a human organ and determine how that organ would respond to different chemicals and other stimuli. Invasive animal experimentation that involves performing surgery on a living animal can be referred to as vivisection, as opposed to dissection, which is surgery performed on a deceased animal.

News about Animals, including commentary and archival articles published in The New York Times. Researchers have developed ways to obtain data without using live specimens by experimenting on cells and tissues, rather than the entire living organism; these procedures are referred to as in vitro experiments. In response, proponents note that humans are not the only beneficiaries of this type of research. The total includes only animals protected by the AWA and omits amphibians, birds, fish, mice, rats, and reptiles, all of which account for the majority of animals used in scientific studies. Animal models of human behavioural deficits involve conducting experiments on animals with the hope of gaining new knowledge that can be applied to humans. In 2019 the efforts of animal rights activists led high-profile companies in other fields, such as food-manufacturers Kellogg Company and Hershey Company, to affirm their opposition to animal testing and end their involvement in such experimentation. Animal experimentation is done to clarify previously unknown life processes and fundamental biologica… About 31.1% of animals in science are used in basic research, while 11.9% are used for translational and applied research, which includes projects that test primary research findings for medical application. Below, I will outline one of the more common arguments used to reach this conclusion.… “There was a time when dosing and contaminating animals with often toxic levels of chemicals was horrible for them but imperative for human health and safety.”. US schools began incorporating dissection into biology instruction in the 1920s, with the practice becoming widespread by the 1960s. Nonhuman animals are used in laboratories for a number of purposes. See More Articles >>. Find science articles about animals from Popular Science. The AAVS maintains that animal studies do not reliably predict human outcomes, that most drugs that appear promising in animal studies go on to fail in human clinical trials, and that reliance on animal experimentation can delay discovery. Proponents argue that this method produces data that is more relevant to human safety. Revisions to the law, the authors maintain, will encourage companies to employ alternative methods for gathering data and work with other companies to reduce instances of duplicated experiments. Congress has enacted several pieces of legislation to regulate animal experimentation and prevent animal abuse, including the Animal Welfare Act (AWA), first passed as the Laboratory Animal Welfare Act in 1966, and the Improved Standards for Laboratory Animals Act (ISLAA), passed as part of the Food Security Act of 1985.

The Institute of Medicine deemed the use of chimpanzees in scientific research unnecessary in a 2011 report commissioned by the NIH. Many of these experiments cause pain to the animals involved or reduce their quality of life … A review of 101 high impact basic science discoveries based on animal experiments found that only 5% resulted in approved treatments within 20 years. Companies and research facilities, however, can be slow to adopt alternatives. The National Aeronautics and Space Administration (NASA), for example, sent several nonhuman primates into space before sending human astronaut Alan Shepard in 1961. There are many positive things that can be listed for animal experimentation. In 2009, for example, the Organization for Economic Cooperation and Development (OECD) approved two alternatives to the Draize test, a research method that involves applying chemicals directly to the eyes or skin of animals, typically rabbits. As a researcher himself, Baker maintains that the primates he used in his experiments willingly cooperated and did not exhibit any signs of stress. OOCs are approximately the size of a deck of playing cards and have been developed to imitate lungs, hearts, kidneys, skin, eyes, and entire organ systems. The test is widely condemned by animal rights activists. In 2013 the NIH announced its intentions to stop providing funding or granting research requests for experiments involving chimpanzees, and the USFWS proposal was finalized in 2015. This report was followed by a proposal by the United States Fish and Wildlife Service (USFWS) to include captive chimpanzees, such as those used in research facilities, on the list of animals protected by the Endangered Species Act; chimpanzees in the wild had already been protected by the act since 1990. Animal experiments help scientists understand diseases that afflict animals and humans. "Experimenting with animals before testing on people is a crucial human rights protection required by the famous Nuremberg Code.".

Animal behaviorists, noting the chimpanzee's intelligence and capacity for emotion, raised concerns that the use of chimpanzees in experiments amounted to torture. This Overview provides a brief summary of the ethical and scientific considerations regarding the use of animals in research and testing, and accompanies a Collection entitled Animals, Research, and Alternatives: Measuring Progress 50 Years Later, which aims to spur ethical and scientific advancement. To protect research companies and other commercial enterprises vulnerable to animal rights violence, Congress passed the Animal Enterprise Protection Act of 1992 and the Animal Enterprise Terrorism Act of 2006. The amendment was not adopted, nor was it adopted when reintroduced in nearly every subsequent session of Congress, most recently in 2019.

Some cosmetic manufacturers, including Procter and Gamble and Unilever, have called on the industry to adopt a global ban on testing. In 2018 researchers successfully tested OOCs that imitated interconnected organ systems and could produce data for twenty-eight days, indicating that a microdevice could likely support an entire ""human on a chip."" In the following viewpoint, Wesley J. Smith argues that research on animals has been indispensable in developing ways to treat human disease. The pursuit of alternatives has largely centered on concepts first introduced in 1959 by British zoologists W. M. S. Russell and R. L. Burch in The Principles of Humane Experimental Technique.

Using animals in research and to test the safety of products has been a topic of heated debate for decades. In 2015, two animal rights activists, Kevin Johnson and Tyler Lang, challenged the constitutionality of the Animal Enterprise Terrorism Act after they were charged with violating the act for vandalizing a mink farm and setting hundreds of animals free. Critics of in vitro methods argue that operating on a live animal provides more accurate data because the effects on the entire organism can be observed. Many of the responding teachers, however, reported that their schools were shifting away from dissection and pursuing alternatives, such as virtual dissection programs, 3-D models, and videos, largely in response to student requests. As of 2019, despite the availability of these alternatives, scientists continue to perform the Draize test, arguing that no single test has proven able to replicate the full benefits of the Draize test. Many laboratories worked with chimpanzees throughout the twentieth century. Despite the amendment repeatedly failing to become law, the National Institutes of Health (NIH) adopted rules in 2012 and 2014 that ended NIH funding for research involving cats and dogs from Class B or unlicensed dealers.
