It is unclear at exactly what point the phrase "stem cell" entered the vernacular, one of very few scientific terms that achieve the status of, say, DNA in not requiring a detailed explanation every time it is written down or spoken.
Whether or not you know exactly what they are or what they do, stem cells imply something very specific: in them is invested the next generation of medicine, revolutionary treatments for everything from Parkinson's to Alzheimer's. On the horizon, there is also the hope of growing genetically matched tissue (even whole organs) to replace anything that has been damaged by disease or accident.
But perhaps the reason stem cells managed to lodge themselves so deep in the public psyche was not just because of their awesome scientific potential, or their ability to turn into the treatments of the future. Perhaps it was politics. For years, stem cells dominated all other science stories in newspaper headlines because they framed an ethical conundrum – to get to the most versatile stem cells meant destroying human embryos.

Several recent Biopolitical Times posts (1, 2, 3, 4) have called attention to the alarmingly rapid commercialization of “designer baby” technologies: polygenic embryo screening (especially its use to purportedly screen for traits like intelligence), in vitro gametogenesis (lab-made eggs and sperm), and heritable genome editing (also termed embryo editing or reproductive gene editing). Those three, together with artificial wombs, have been dubbed the “Gattaca stack” by Brian Armstrong, CEO of the cryptocurrency company...
Alice Wong, founder of the Disability Visibility Project, MacArthur Genius, liberationist, storyteller, writer, and friend of CGS, died on November 14. Alice shone a bright light on pervasive ableism in our society. She articulated how people with disabilities are limited not by an inability to do things but by systemic segregation and discrimination, the de-prioritization of accessibility, and the devaluation of their lives.
We at CGS learned so much from Alice about disability justice, which goes beyond rights...
