Scientists have created a human-pig hybrid in a milestone study that raises the prospect of being able to grow human organs inside animals for use in transplants. From a report: It marks the first time that embryos combining two large, distantly-related species have been produced. The creation of this so-called chimera — named after the cross-species beast of Greek mythology — has been hailed as a significant first step towards generating human hearts, livers and kidneys from scratch. Juan Carlos Izpisua Belmonte, who led the work on the part-pig, part-human embryos at the Salk Institute for Biological Studies in La Jolla, California, said: “The ultimate goal is to grow functional and transplantable tissue or organs, but we are far away from that. This is an important first step.” The study has reignited ethical concerns that have threatened to overshadow the field’s clinical promise. The work inevitably raises the spectre of intelligent animals with humanised brains and also the potential for bizarre hybrid creatures to be accidentally released into the wild. The US National Institutes of Health (NIH) placed a moratorium on funding for the controversial experiments last year while these risks were considered.

Longtime Slashdot reader Stunt Pope writes: Customer Feedback surveys are now near-ubiquitous, subjecting us all to near-Black Mirror-esque pursuit to “rate your experience” for everything from going to the bank to ordering a pizza. Thanks to The Curse of Goodhart’s Law, all of these surveys are beyond useless and even damaging. Mark Jeftovic writes in a blog post: “The shop/hire-rate-reward feedback loop has become baked-in to some systems. Many live marketplaces incorporate these feedback transactions into ratings, which then become a score which then impacts future prospects of whomever is being rated. And that’s where the trouble starts. There is a point where this stops being useful and the knock-on effects of a ratings system predicated on feedback results becomes counter-productive. That point is when the ratings become targets. When a company decrees ‘All customer feedback ratings must score a minimum of X, or else…’ the company has just commenced the process of invalidating and corrupting all useful information to be gleaned from that feedback/survey process. A label which captures this concept is ‘Goodhart’s Law’ — after economist Charles Goodhart, who posited in essence that ‘when a measure becomes a target, it becomes useless.'”
