When I was a graduate student back in the dark ages, I took an advanced statistics course and then briefly worked in a laboratory where statistical analysis of data derived from animal models of disease (in this case the guinea pig model of tuberculosis) were essential. After leaving that lab, I developed an appreciation for the power of statistics (when appropriately designed according the laws of parametric statistics) and actually used statistical analyses of in vitro data for my PhD thesis. Unlike me, most of my contemporaries never understood statistics and thought that statistics can be used to manipulate data to confirm any hypothesis put forth by an investigator.

Imagine my surprise when I read in today’s NY Times that statistics are one of the hottest new career opportunities in technology and related industries. This is because billions of bytes of data (aka "big data sets")are generated daily and someone (usually a statistician or a person with knowledge of some arcane statistical analyses) is regarded to tease out trends and interpret the data. Companies like Google, Facebook, as wells as marketers, risk analysts, spies and companies that engage in competitive intelligence are desperately seeking new employees who understand applied statistic, analytics and trend analysis.

According to a recent LinkedIn survey, from 2009 to 2011 the number of new jobs with titles related to analytics grew 53%. Unfortunately, there are not enough trained or qualified persons available to fill these positions at most of these companies. Because of workforce shortages, universities like Stanford, Harvard and North Carolina State (NC State) have created graduate programs to train students in statistics and advanced analytics. 

Ninety per cent of NC State advanced analytic students (a 10 month program created in 2006) annually found jobs. The average graduate’s starting salary for an entry-level job is $73,000. Stanford and Harvard statistics department graduates head to Google, Wall Street and in many instances bioscience companies and start with salaries of over $100,000.

Not surprisingly, competition for entry to these programs is getting fierce. NC State takes only 40 new students per year in its program (185 applicants last year). Moreover, this year, Stanford received over 800 applications for 60 openings in next’ years class; nearly twice the number of applications that it received three years ago.

Like it or not “big data” and analytics are de rigueur and persons with advanced analytics training may be the new rock stars. That said if you like statistics or love to look for trends in large data sets then a career in analytics may be right for you. Now, you have to figure out where to get the training.

Until next time...

Good Luck and Good Job Hunting!!!!!!!.

Yesterday, a bill to designate Lactococcus lactis (formerly Streptococcus lactis) the official state microbe passed the Wisconsin assembly and now awaits action in the state senate. L. lactis is the bacterium used to make cheese, and as many of you know Wisconsin makes a lot of cheese.

As many of you may know, I received my PhD in Bacteriology from the University of Wisconsin-Madison and it was Ken Todar, my former mentor, friend and teacher extraordinaire (now emeritus) in the department who originally lobbied the state legislature to consider selecting L. lactis as the state microbe.

The bacterium is poised to join the state’s list of 21 designated symbols, which includes an official dance (the polka), beverage (milk) and domesticated animal (the Holstein dairy cow).

To learn more about L. lactis and its possible ascendancy as the first ever state microbe designation, listen to a podcast of an interview with Elio Schaechter, PhD, former longtime Chair of the Department of Microbiology at Tufts University, past President of the American Society for Microbiology and science education advocate.

Finally, I will be back in Madison next month to attend a meeting where my mentor, Bob Deibel (now 86 or so), will receive a lifetime achievement award for his work in food microbiology. This will be my first visit back to UW since the mid 90s. I am especially looking forward to eating a brat and drinking a few steins of Leinnies on terrace! Maybe I will be lifting a few to toast L. lactis as well!

Until next time…

We all know (or should know) that eating dirty or yellow snow is a big “no-no”. Those of us who are parents (and live in regions where there are regular snowfalls) teach our children this lesson as quickly as possible. That said, should parents worry when their children eat new or freshly falling snow because it contains air-borne bacteria? 

Last week, a group of scientists at Louisiana State University reported in Science magazine that there may be a relationship between ice-nucleating, air-borne bacteria and global rainfall patterns. For those of you who don’t know, the formation of ice in clouds is required for snow and most rainfall. Although dust and soot particles serve as ice nucleation particles, bacterial ice nuclei are capable of catalyzing freezing more quickly at much warmer temperatures and their presence in the atmosphere may affect the processes that trigger precipitation. Results from the Science study suggested that bacteria like Pseudomonas syringae, which have long been know to serve as nucleators and induce ice formation, are widely distributed in the atmosphere and likely play critical roles in influencing the amount of rain that falls at various locations in the world–pretty cool new stuff for those of us interested in global warming and climate change in general. Therefore, it surprised me when I saw that lay newspaper reporters chose to “cherry pick” data from the paper to suggest to Americans that even freshly fallen snow contains large numbers of bacteria and that, perhaps, parents should be careful when they allow their children to eat snow!

As a card-carrying microbiologist and seasoned science educator, I want to assure all of you that eating freshly fallen snow will not cause disease in you or your children. The types of bacteria found in the atmosphere, and ultimately in snow, are not human pathogens and don’t cause disease. Thankfully, in a story entitled “Study: Driven snow isn’t all that Pure” that appeared in my local paper (The Trenton Times)– a member of the American Academy of Pediatrics Committee on Environmental Health was quoted as saying ; “We eat stuff that’s covered with bacteria all the time, and for the most part, it is killed in the stomach.” Another pediatrician, who is a member of the academy’s committee on infectious diseases, reinforced the claim that snow munching was not harmful and said “Children practically bathe in bacterial when they go to the playground and they won’t get anything from snow that they would not get from dirt.”  

Although most of the stories about bacteria and snow munching that appeared in the lay media were “fluff pieces”, they did alarm some parents! As one mother said in the Trenton Times article: “When I heard bacteria, at first, I went “eeeewwww”. But as long as the kids eat snow as it’s falling, I think it is okay. I tell them not to eat it if it’s on the ground.” What was particularly troubling about her remark was her initial negative reaction to the mere mention of the word bacteria. Unfortunately, most Americans have little understanding about bacteria and the negative impressions that they have formed are based on the sensationalistic and often scientifically inaccurate pieces about “dangerous” bacteria and fungi (mold) that often appear in print media and on television.

In my opinion, America’s negative attitude and poor understanding of science is a consequence of ongoing, misguided science reporting that has plagued this country for years. Although the American lay news media is mostly responsible for this, scientists are also complicit because of their unwillingness or inability to publicly speak out on important scientific issues and problems.

I believe that scientists are obliged to do everything in their powers to ensure that lay science reporting is fair and balanced and that the correct scientific messages reach the American public. Our failure to act will surely jeopardize the future of American science–something that we Americans can ill afford. Enough said–have a plate of snow on me!

Until next time….
