Controversial Genetic Experiments

Scroll down to explore a learning path based on this topic.
Playlist Description

History is saturated with stories of controversial genetic experiments. Cloned sheep. Human-animal crossbreeding. Cats that glow in the dark. Those aren't "X-Files" re-runs, they're actual genetic experiments that have taken place in scientific labs around the globe. Sometimes secretive, sometimes within the public's radar, genetic experimentation has been notoriously embedded in controversy since the pseudo-science of eugenics became common practice during the 1930s and '40s. In the spirit of genetic cleansing and purity, many believed they could discern a person's level of intelligence, religion, sexuality and ethnicity through specific measurement ratios, like head circumference to nose length. By casting away those who failed to pass the threshold for purity standards, doctors, researchers and politicians hoped to create a superior race. Opponents of genetic experimentation argue experiments are often racially and ethnically charged, cite moral concerns and say it devalues natural life. So are there any positive takeaways?

Indeed it appears as if experimenting with genetic makeup has allowed doctors and scientists to team up in some beneficial (and fascinating) ways: growing artificial organs for transplant patients, helping hopeful parents artificially conceive and pushing the scientific envelope by cloning animals. So what do you think about genetic experimentation? Can stem cell research save lives, or is trying to control fate dangerous? Watch, learn and decide for yourself here.

Scientists have cloned a human embryo, and from those clones, extracted stem cells. It's a first that could transform medicine. But as Anthony tells us, the ongoing battle over stem cell research could make this advancement DOA.

Scientists have promised that gene therapy will be the next big leap for medicine. It's a term that's tossed about regularly, but what is it exactly? Trace shows us how scientists can change your very genetic code. Read More: How does gene therapy work? http://ghr.nlm.nih.gov/handbook/therapy/procedures "Gene therapy is designed to introduce genetic material into cells to compensate for abnormal genes or to make a beneficial protein. If a mutated gene causes a necessary protein to be faulty or missing, gene therapy may be able to introduce a normal copy of the gene to restore the function of the protein." Gene therapy trial 'cures children' http://www.bbc.co.uk/news/health-23269778 "A disease which robs children of the ability to walk and talk has been cured by pioneering gene therapy to correct errors in their DNA, say doctors." Gene therapy cures diabetic dogs http://www.newscientist.com/article/dn23163-gene-therapy-cures-diabetic-dogs.html "Five diabetic beagles no longer needed insulin injections after being given two extra genes, with two of them still alive more than four years later." Gene Therapy for Cancer: Questions and Answers http://www.cancer.gov/cancertopics/factsheet/Therapy/gene "Gene therapy is an experimental treatment that involves introducing genetic material into a person's cells to fight or prevent disease." How does gene therapy work? http://www.scientificamerican.com/article.cfm?id=experts-gene-therapy "Gene therapy is the addition of new genes to a patient's cells to replace missing or malfunctioning genes. Researchers typically do this using a virus to carry the genetic cargo into cells, because that's what viruses evolved to do with their own genetic material." Gene therapy cures leukaemia in eight days http://www.newscientist.com/article/mg21729104.100-gene-therapy-cures-leukaemia-in- eight-days.html WITHIN just eight days of starting a novel gene therapy, David Aponte's "incurable" leukaemia had vanished. For four other patients, the same happened within eight weeks, although one later died from a blood clot unrelated to the treatment, and another after relapsing. Cell Therapy Shows Promise for Acute Type of Leukemia http://www.nytimes.com/2013/03/21/health/altered-t-cell-therapy-shows-promise-for-acute-leukemia.html?pagewanted=all&_r=0 "A treatment that genetically alters a patient's own immune cells to fight cancer has, for the first time, produced remissions in adults with an acute leukemia that is usually lethal, researchers are reporting."

Safe doesn't mean acceptable. Marion Nestle: The Food and Drug Administration has ruled that meat from cloned animals is safe for human consumption, and has approved cloned animals for introduction into the food supply.  On the same day that the FDA made that announcement, the Department of Agriculture came out and said, "Yes, but please don't do it.  Don't bring that food into the food supply because it's gonna cause a lot of trouble.  People don't want it.   Marion Nestle: The Food and Drug Administration has ruled that meat from cloned animals is safe for human consumption, and has approved cloned animals for introduction into the food supply.  On the same day that the FDA made that announcement, the Department of Agriculture came out and said, "Yes, but please don't do it.  Don't bring that food into the food supply because it's gonna cause a lot of trouble.  People don't want it.

In the early days of the space race, agency researchers in Russia and at NASA really weren't sure all what would happen to an astronaut in space. They didn't know if a human mind could handle actually seeing Earth or what would happen to the human body when exposed to long periods of weightlessness. Would their blood forget which way to pump? Would their eyeballs shift or their inner ears wig out? They sent up mice and monkeys and dogs, to see what happened, and in 1961, the Russians strapped a man to a rocket headed for orbit. Yuri Gagarin was the first person in space. The ultimate human guinea pig, he survived, becoming an international hero. Like SciShow?

A male fruit fly attacks a female fruit fly. The female has been genetically altered to produce male pheremones and to exhibit male-like behavior. This work was completed in the laboratory of Edward Kravitz, the George Packer Berry Professor of Neurobiology at Harvard Medical School.
