Bedau said there are legitimate worries about creating life that could “run amok,” but there are ways of addressing it, and it will be a very long time before that is a problem.
“When these things are created, they’re going to be so weak, it’ll be a huge achievement if you can keep them alive for an hour in the lab,” he said. “But them getting out and taking over, never in our imagination could this happen.”
I hope that’s not attributable to a mere lack of imagination…
There’s been a very interesting discussion in comments over at Space Politics about VSE, ESAS, and public perception. Jim Muncy challenges us to an exercise:
I would respectfully request everyone ask themselves two separate and distinct questions. Answer them independently, in any order you want.
While it was obviously (from its title) of partisan intent, it was well researched, and did make a good case for it. And it even purported to attempt to appear bi-partisan, by pointing out a few examples of political attacks on science from the left. However, it gave them extremely short shrift, in my opinion. Here’s just one example of the kind of thing with which he could have balanced the book, had he truly wanted to.
My problem with Chris’ book is that it was too polemical, when he had an opportunity to make a serious point–that science is continually under assault by people with an agenda from all points on the political compass. By attempting to make it a partisan issue, it results in a misdiagnosis of the problem. After all, if it’s only a “Republican” war on science, then the solution is simple–elect Democrats. Unfortunately, the problem is much more complex than that, and the notion that it’s not holds us back from finding a real solution.

Scientists have suspected for decades that exercise, particularly regular aerobic exercise, can affect the brain. But they could only speculate as to how. Now an expanding body of research shows that exercise can improve the performance of the brain by boosting memory and cognitive processing speed. Exercise can, in fact, create a stronger, faster brain.
This theory emerged from those mouse studies at the Salk Institute. After conducting maze tests, the neuroscientist Fred H. Gage and his colleagues examined brain samples from the mice. Conventional wisdom had long held that animal (and human) brains weren
