Does DNA really have a “half life”? Physicist Rob Sheldon is skeptical

Sheldon: “As a physicist, I would like to point out that biologists are misusing the word “half-life”. DNA does NOT have a half-life of 521 years. Radioisotopes have a half-life, because the nucleus is unstable to natural decay through the weak force (for isotopes of interest).” He goes on to say that the weak force of the universe “is unaffected by temperature, pressure, time, or chemicals.” Not so for DNA.

Cell biology Genetics Intelligent Design

At New Scientist: “single-celled organism that lacks most of the molecular equipment needed to kick-start DNA replication”

It’s a protist? “Protists are a group of loosely connected, mostly unicellular eukaryotic organisms that are not plants, animals or fungi. There is no single feature such as evolutionary history or morphology common to all these organisms and they are unofficially placed under a separate kingdom called Protista.” In short, just the sort of life form that might be doing something really different. Because nature is full of intelligence, there are probably many alternative programs out there. It all didn’t just somehow happen randomly once.

Intelligent Design Mind Psychology Science

When psychology tries to be a science instead of a mythology…

Gabriel encourages us to see psychology as a mythology and, of course, he is right: “Sigmund Freud’s theories were largely unfalsifiable, and the promissory note that the mind is the brain has yet to be cashed in.” The idea that the mind is just the brain is unfalsifiable too. Beliefs that do not originate in fact are impervious to evidence.
