When television first became popular around 1950, it was dominated by such shows as the Milton Berle comedy hour, “I Love Lucy,” and professional wrestling. Those who missed out on the halcyon days of early television might enjoy reading about its history . The potential for a damaging impact on education was recognized at the outset. In 1950 Boston University's President Dr. Daniel L. Marsh warned that “if the [television] craze continues with the present level of programs, we are destined to have a nation of morons.” Well here we are. Just look at how voters re-elect incompetents, panderers, and demagogues. Quick to jump into the breach anticipated by the brain-eating monster of TV, a new movement of “educational TV” sprang up . National Educational Television was born on May 16, 1954 and was a non-profit effort to bring educational programs to the masses. The network was not sustainable as such and was transformed into the Public Broadcasting Service (PBS) in October, 1970, whic...

In recent years scientists have discovered mobile pieces of genetic material that move around inside cells. These pieces are called retrotransposons. They can copy themselves and insert near and into DNA and thus induce mutations. Australian research recently reported in the journal  Nature  reveals that retrotransposons can alter the genome of human brain cells. In fact, retrotransposons more effectively penetrate neuron genes than those in blood cells that were used for comparison. Thousands of retrotransposon mutations were seen in two of the five areas examined from brains of human post-mortem donors. Though these pieces of DNA are not genes, they interact with genes that hop around to different sites within a chromosome (perhaps you heard about Barbara McClintok’s 1983 Nobel Prize winning discovery of “jumping genes”). All cells have enzymes that cut transposons out of a string of DNA, which then insert back in at other locations in the DNA. Sometimes the cut includes an ...
