Science for science writers
Science News blogs from Austin, Texas, where the 47th annual New Horizons in Science meeting is taking place. Freelance Laura Beil describes how Skip Garner began his accidental journey into scientific misconduct investigation after he developed a computer program that could, as he put it, “help a physicist understand medicine,” he told writers in the audience at the Council for the Advancement of Science Writing symposium. Got milk tolerance? Your ability to digest lactose as an adult is relatively new in the human species. And, said John Hawks of the University of Wisconsin-Madison, provides evidence of rapid evolution over the past 10,000 years, Elizabeth Quill reports in this blog from the meeting. Virgil Griffith’s life goal is “to create a machine who feels.” Griffith, a doctoral student at Caltech, isn’t the only one. During his talk, he revealed that turning people into cyborgs is the secret passion of many of his Caltech peers, Rachel Ehrenberg reports. (They contend that they are working on implant devices for the injured bodies of people like Vietnam vets, says Griffith, but if you get them drunk they’ll confess that the real aim is to make cyborgs of us all.) Also, blogging from: Eva Emerson on some new results on longevity without caloric restriction in yeast; freelance Susan Gaidos on a Boston University medical statistician who has devoted lots of time to studying errors in the voting process, and says things can, and do, routinely go wrong; and Lisa Grossman on how mapping fossil fuel emissions may help scientists find where carbon is hiding in the biosphere.
