Eric’s Enlightenment for Tuesday, April 28, 2015

  1. On a yearly basis, the production of almonds in California uses more water than businesses and residences in San Francisco and Los Angeles combined.  Alex Tabarrok explains why.
  2. How patient well-being and patient satisfaction become conflicting objectives in hospitals – a case study of a well-intended policy with deadly consequences.  (HT: Frances Woolley – with a thought about academia.)
  3. Contrary to a long-held presumption about the stability of DNA in mature cells, Huimei Yu et al. show that neurons use DNA methylation to rewrite their DNA throughout each day.  This is done to adjust the brain to different activity levels as its function changes over time.
  4. Alex Yakubovitch provides a tutorial on regular expressions (patterns that define sets of strings) and how to use them in R.
