Whenever you hear "all scientists agree" or "we now know," it's no guarantee a finding won't be disputed years later. In the following examples, CEH focuses not so much on the content of the disputed subjects as the implications for philosophy of science.
If you thought work on human cloning and embryonic stem cell research went out of style with the discovery of induced pluripotent stem cells, watch out. The pro-cloning people, who never lost their lust for toying with human embryos, are back.
Complaints about a new diagnostic manual show that psychiatry has a long way to go before being considered a legitimate science. That hope might never be fulfilled.
