Utter garbage article from a pop sci rag. It does the same thing a lot of garbage science does: spends all its time attacking "mainstream science", none of it defending their own positions, and hoping the reader doesn't notice.
And here's the thing: the article focuses its attack on physicalism, but there's nothing necessarily contradictory about physicalism and human psi ability. Some kind of biological radio could very well exist. We simply lack any evidence that it does.
