  • Common Science Fourth Anniversary

    April 19, 2015 at 4:56 pm

    This week is the fourth anniversary of Common Science®. I published my first column, An Introduction to Your Host, on April 25, 2011 and last’s week’s column was my 200th. This means I have averaged 50 columns per year! Since persistence and reliability are characteristics I strive towards, I take a good measure of satisfaction […]

  • Toxic Substances Control Act: A Redo After 40 Years

    April 12, 2015 at 8:51 pm

    While the 1970s are better known for leisure suits and (in my opinion) great music, they were also a bit of a golden age for environmental regulation. The 1970s brought us the Clean Air Act and the Clean Water Act, and in 1976 Gerald Ford signed the Toxic Substances Control Act (TSCA) into law. While the […]

  • Please Stop Rotating the Scrabble Board

    April 5, 2015 at 8:34 pm

    Several years ago, I took a test at the Museum of Life and Science designed to determine whether I was better at remembering things that I hear or things that I see. The results were what I expected: my visual memory is far better than my auditory. I have known since I was young, at […]

  • Salt and South Florida

    March 30, 2015 at 11:22 am

    In the spring of 2012, I wrote a five-part series on water. In Part IV: When the Well Runs Dry, I explained the process by which salty ocean water can infiltrate subsurface, fresh water aquifers and the problems that creates. Over the last couple of weeks, I have encountered several stories about salt water infiltration in South Florida’s Biscayne Aquifer.

  • STEM Jobs for the 21st Century

    March 22, 2015 at 10:06 pm

    Lately I have noticed a growing trend to encourage people to pursue careers in STEM, an acronym which stands for science, technology, engineering, and mathematics. I find this acronym, developed by the National Science Foundation in the 1990s, to be a bit clunky. My own personal definition of the word “science” has always been broad […]

  • Life on Mars? It’s All About That Methane

    March 15, 2015 at 11:13 pm

    The tantalizing possibility that life may exist on Mars has inspired both scientific exploration and popular culture for a long time. The question of whether we are alone in the universe has recently been reignited by some intriguing data from NASA’s Curiosity Rover, which has been trundling around Mars since 2012. Before we review that […]

  • State of Science, Technology and Industry from 1909

    March 8, 2015 at 7:43 pm

    My wife recently gave me a book titled Outlines of Industrial Chemistry that was published in 1909. It provides a fascinating look at the state of science, technology, the economy, and everyday life from 106 years ago. The book includes an extensive survey of the industrial topics of its day, including fuels, water purification, fertilizers, […]

  • Drug-Resistant Bacteria: Part II

    March 1, 2015 at 8:52 am

    Last week, in Part I of this series, I reviewed the major issues associated with drug-resistant bacteria and discussed the fascinating history of the discovery and uses of bacteriophages. Bacteriophages, viruses that infect and kill bacteria, were first identified approximately 100 years ago. This week in Part II, I will discuss how a discovery made […]

  • Drug-Resistant Bacteria: Part I

    February 22, 2015 at 9:32 pm

    For this week’s column, I am going to presume some knowledge on the reader’s part regarding the growing problem of antibiotic-resistant bacteria. If you are not familiar with this issue, let me recommend that you open a new browser window, do a Google search on “drug-resistant bacteria,” and then come back. If you are not […]

  • Woolly Mammoths and the Voyage of the U.S.S. Jeannette: Part II

    February 15, 2015 at 7:29 pm

    Last week, in Part I of this series, I told you the incredible story of the Arctic journey of the U.S.S. Jeannette in 1879. After their ship was trapped in the ice for 21 months and then sank, the crew dragged their food and supplies over a thousand miles of ice while stopping at some […]
