    • Caster Semenya and the Challenges of Sports Brackets

      Posted on May 3, 2019

      If virtuous perfection of natural talents is what sports is all about, sports needs more people like Caster Semenya, the South African runner. But she is now ineligible for competing in middle distance events unless she takes medication to suppress her naturally high testosterone levels. Is this fair?

    • Rationality as Understood by a Neanderthal

      Posted on April 15, 2019

      The new indie movie William explores the question, What would it be like if a Neanderthal were born and raised in a modern, industrialized society today?

    • Fix the Planet, or Change the Creatures In It?

      Posted on September 27, 2017

      Possibly as many as half of the coral reefs that existed 100 years ago have been destroyed, sometimes by removing them, covering them up, or blowing them up, but mostly just because of climate change, which is gradually heating the water and making it more acidic. The solution everyone who cares about the reefs most… Read more

    • Human Gene Editing Report: Moving Forward Incrementally

      Posted on February 14, 2017

      It’s the conversation that really interests me. The NASEM report is plop in the middle of a national and indeed a global inquiry into how genetic science can let us tweak the world—human beings, human nature more generally, other organisms, ecosystems, the biosphere at large. What are the terms of that inquiry?

    • Challenging Evolution?

      Posted on July 22, 2016

      We have long had the ability, we humans, to work outside the bounds of evolution. Dairy cattle, maize, and all sorts of dog breeds attest to that. It is unlikely that natural evolution alone would have produced these things. They depended on human intervention. However, in the past, the scope of human intervention was rather… Read more

    • Are Arguments about GMO Safety Really About Something Else?

      Posted on August 28, 2015

      The scientific consensus that food containing genetically modified organisms is safe seems ever stronger, yet the social controversy about GMOs seems only to grow as well. “Unhealthy Fixation,” a long article published this summer in Slate and reporting on what author Will Saletan says was close to a year’s worth of research, argues very strongly that GMOs are generally… Read more

    • Altering Nature to Preserve It

      Posted on February 6, 2015

      Perhaps the biggest challenge in talking about something like de-extinction is simply being clear on what it is you’re really talking about. Emerging technologies can be surrounded with so much hoopla that one can lose sight of what the technologies actually accomplish. Somebody recently expressed exactly this caution to me about de-extinction: “That is not… Read more

    • De-Extinction: Could Technology Save Nature?

      Posted on February 7, 2014

      This past November, the International Union for the Conservation of Nature declared the western black rhinoceros of Africa, last seen in 2006, officially extinct. It also concluded that most other rhino species are in danger, even “teetering.” Yet at the same time, over the past year, some scientists and others have been declaring that the… Read more

    • Doctors Googling Patients

      Posted on October 8, 2013

      In the current issue of the Hastings Center Report, two teams of physicians and ethicists at Penn State consider the ethics of using online research and social networking tools to learn more about a patient who came to them with a request for a prophylactic bilateral mastectomy. The patient’s story doesn’t quite sound right to the… Read more
