The Brave New World of CRISPR

Can you imagine an elephant sanctuary in Siberia?  Wheat that is practically immune to mildew?  Microbes that eat plastic? These may now be possible, thanks to a new tool called CRISPR-Cas9 (or CRISPR for short) that gives us the ability to literally rewrite genetic code for just about anything on our planet that has DNA.

In Praise of Unsung Heroes

A major problem with studying history is you have to dig to get the real story.  So much gets left out of the standard history books. One of my favorite examples is Rosalind Franklin, whose pioneering work in X-ray crystallography enabled James Watson, Francis Crick, and their colleague Maurice Wilkins to discover the structure of

Some Personal Disney Memories

How big an influence has Disney had on my life?  Uncle Walt was personally responsible for two of the most unusual experiences of my childhood. I remember my first Disney memory was watching the “Disneyland” TV show.   It was an episode of Davy Crockett fighting Indians under General Andrew Jackson, so it must have been

Does Cuteness Give Babies an Advantage?

It certainly seems that being handsome/pretty is an advantage for adults, but what about babies?  Can cuteness give them an evolutionary advantage? The latest research suggests yes, at the brain level, attractive infants seem to have a definite edge.  In an article on the New York magazine website (http://nymag.com/scienceofus/2016/06/cute-babies-have-an-evolutionary-advantage-in-life.html?) — “Cuteness in offspring is a
