STEM Interest: How Can I Help?

I have wanted to write something for quite a while but have not had the proper inspiration (or motivation). When in doubt, go with your recurring thoughts. For me, this includes interest in the STEM fields locally or globally via the internet.


I recently did a search for local STEM organizations that I could volunteer my time or efforts. Knoxville, however, is not really considered a STEM-Mecca. Actually, I did not find a single NPO focusing on science. This was not a huge shock, but it was a huge disappointment. I know I am not the only Ph.D.-strapped person in the area who could potentially help spread science literacy or interests.


In graduate school, my major professor did talks at local middle schools that we gladly went to so these students could see what an actual scientist looked like. We were an eclectic bunch just like the science community itself. We could tell the students enjoyed and appreciated our visits, and hopefully some of them will pursue a career in a STEM field. I now try to fuel interest in my own undergraduate classroom for my students. I’m not satisfied with my current reach and would love the opportunity to expand it. The best way to a future with progress and prosperity is through a logical and literate society.


I do my little blog with my little graphics and illustrations. What else can I do? I need to channel my passions for spreading the science in a focused and steady way. So, I need your help: help me help others.

The Microbiome: Can We Please Consider the Human Body an Ecosystem Now?

It has long been thought the type and amount of microbes using the human body as a home shape the way we live and behave. The microbiome as it is known is shown to have a greater and greater impact in our daily lives.

A new study published in Nature (paywall) provides evidence demonstrating the artificial sweeteners we all love and consume to control weight leads to increased blood glucose levels. How can something used to replace sugar in consumables raise the amount of sugar in the blood?

Like many other answers regarding human health, look no further than the microbiome. Consuming artificial sweeteners alters the composition of the intestinal microbes leading to a growing glucose intolerance. The researchers linked artificial sweetener use to altering metabolic pathways within the microbiome that leads to increased susceptibility to metabolic disease.

To verify their findings, researchers gave antibiotics to the mice used as models thus reversing the effects of artificial sweeteners. Results were also verified by using fecal transplantation in the mice to reverse glucose intolerance.

The Human Microbiome: Our Ecosystem

We already knew the microbes outnumbered our human cells 10 to 1 and that the microgenome outnumbered our human genome 100 to 1. The evidence is growing suggesting our normal flora govern more of our lives than we naively assumed for decades. We are not individuals but individual incubators for the microbial overlords that we could not live without. Just like other ecosystems, changing our lifestyles have a complicated effect on system as a whole. Small alterations to the microbiome can have major impacts and be the difference between health and disease.

Future posts will hopefully provide evidence demonstrating how we are shaped into individual ecosystems. Thank you, microbiome.

A Career Change is Quite Literally a Dream Changer

Those who may know me also know I can have weird or vivid dreams on a regular basis. For as long as I can remember, I have had dreams of tornadoes at least once a week. Another recurring dream subject for many years has been airplanes. Me on an airplane. You might not think anything of it, but some of these ‘airplanes’ were actually non-flying objects like a passenger van or a pharmacy in the basement of a local hospital I used to work. One of these dreams I clearly remember because I was flying the plane from a second cockpit in the plane’s ‘attic’ and had to continuously put oil on a gear to keep the plane in the air.

Over the past year, these airplane dreams have expanded to airports. Me in an airport. You might not think anything of it, but some of these airports were very small; the size of a restaurant (with bar). A year ago, I lost what I considered the perfect job promoting and writing about science emerging from one of the Departments of the U.S. The airport dreams started around the same time I was laid off.

I recently had a dramatic change in my recurring dreams. I no longer am at an airport or on a plane between airports. Suddenly, my method of transportation was not by air, but by sea; ships, cruise ships to be exact. Sometimes these ships were floating hotels with thousands of people watching high school basketball or attending a conference. Sometimes my family was on board and other times I knew no one aboard the boat.

I recently had a career change from science writer to science instructor at a local college teaching the wonderful subject of Biology. This is something I am very fond of and no stranger to with my Ph.D. in biochemistry, cellular and molecular biology. My passion for promoting science to the masses had to be honed to promoting science to the classes.

What does this have to do with dreams?

Dream interpreting is not one of my hobbies, but this one is quite easy for me to discern. Airplanes are a way to travel great distances in a short amount of time. One can cross the globe and be back home in a day or so. Imagine the sheer amount of contact a person can have with people on that journey. The airports were just a mode of transition. The dreams were no longer about flying but instead about what happened after landing. It was time to slow down.

What about the cruise ships? Ships don’t travel at break-neck speed, but they can get a person across the ocean or gulf and back within a week or so.This leaves ample time to explore the ship and get to know the people aboard; learn their stories and backgrounds. It gives time to tailor your message to those whom you see daily for a period of time until the next cruise when you start over with a new group of passengers.


There you go; a career change from science writer to science instructor. Or, as my brain sees it, jet setter to cruise ship director perhaps.


Now, if I only knew what the heck all the tornado dreams were about…

Academia as an Unwieldy Vortex

Vortex of Academia

 The safety of academia

In the fall of 2012, I left the comfortableness of the lab in which I had been nestled for 6 years. It was an exciting and terrifying time. I was not going the normal tract for a new Ph.D.; a post-doctoral fellowship. Are we not steered towards a career in academia? I was warned by several professors to make my choice wisely (and for good reason). My wife and I had a life in my town and the thought of uprooting for two to 8 years did not sound appealing. I was very fortunate to take a position as a science writer helping a federal department’s program in biological and environmental research. It was new territory for me, but I knew the opportunity was too great to pass up.

Exactly one year later, I found myself out of work due to reduction in force. I had never gone through such a thing. Those words when they were spoken to me gave me a sort of out-of-body experience, a nightmare really. It took weeks for me to come to grips fully of the immense toll it would take on my family.

Back to the applicant pool

Being a Ph.D. in a mid-sized market is a daunting thing. It seemed as if I was over-qualified or in the running with about 50 other sorry Ph.D.s for each position in which I applied. One part-time position became available as I was hitting the unemployment line as an adjunct professor at a local college. I was teaching ‘Health Science Research’. A great and appealing position if I knew exactly what health science research was. My wife was not as thrilled as I in this opportunity. Who knows, I could land a full-time position soon, I thought. I gladly took the position and kept searching for something permanent and life-sustaining. By early 2014, I had found a hand full of part-time spots to keep us afloat. I was looking several times a day at career sites and every other job portal for the biggest employers in the region. My search had grown to opportunities an hour a way from home. Academia, industry, government; it did not matter to me. I had mouths to feed.

Oh boy, what luck, er tragedy

My adjunct employer asked me to teach additional courses in the summer. However, this schedule overlapped with my wife going back to her position as an elementary school teacher. This meant we would have to pay childcare for a newborn. In other words, we would have to pay the equivalent of another small mortgage monthly for me to work. A catch 22 if ever there was one, but my boss knew my incredible urge to be taken on full-time.

A few weeks after regretfully declining the offer, I received an email on a Sunday morning from my adjunct boss. A faculty member in the Science Department was on life support after a ruptured aneurysm. I was asked to step in (in the middle of the quarter) and teach three additional classes starting the next day. I had no choice but to accept out of respect and duty. The next morning, I found out the faculty member passed away. I couldn’t be happy for my good fortune. How could I? His mother had lost her husband and son within 6 weeks time.

So, here I am stepping into a full-time role with two mid-term exams and a quiz my first week to prepare; not to mention hours of lectures to prepare with no slides to reference from previous quarters. I have not, and will not, complain about my circumstance. I think of his mother and sisters often.

Home Sweet Home

18 months after leaving the world of academia, I find myself thrown back into a forceful vortex. No time to stop and think about ivory walls or effective pedagogy. I’m treading the academic waters for a few more weeks. Going one lecture/class at a time trying to give the students my best efforts, for their sake. Don’t get me wrong, I want to become increasingly effective at teaching my students and getting them curious in biology. Just let me turn in final grades for this quarter first.

Earth: This is Our One Shot, Don’t Blow It

Tomorrow morning, early tomorrow morning, my wife and I are heading to the hospital for a scheduled C-section. I’m going to meet my son. Over the next 20 years or so, my duty as a father is to mould and shape him into an honourable and respectable human being. This is something I do not take lightly for it is one of the purest legacies we leave.

I found myself watching Carl Sagan’s Cosmos Episode 13 this evening entitled: Who Speaks for Earth?. I was in awe of the profound and prophetic words and some points stuck with me. First, Sagan spends some time crafting an image of past civilizations with a comparison between the Greeks and Egyptians. With his explanation that Aristotle believed in two groups; Greeks and Barbarians, this concept rationalized the practice of slavery. There was no sense of a collective community to Aristotle. Sagan also explained the city of Alexandria as the first true cosmopolitan city. It was the heartbeat of innovation and discovery. Its library held invaluable volumes detailing observations and methods. It was not until the mob mentality of the religious deemed the library and its possessions as pagan that the library was razed to the delight of local politicians. It was at this point one of the most poignant statements I have ever heard was uttered…

History is full of people who out of fear or ignorance or the lust for power have destroyed treasures of immeasurable value which truly belong to all of us. We must not let it happen again.

Let that sink in….

My first instantaneous thought was of the Koch Brothers. Scientific discoveries do not belong to any one party or country. These discoveries belong to all of us because they tell of our shared kindredship. We are all in this together.

My second thought deals with the conviction Carl Sagan has to calm the rising nuclear storm among world powers, and he does it in blaring subtlety.  He could see the big picture; how all civilization could end within a short, short period of time. Thankfully, these tensions seem to have died down enough that it is not an imminent threat. But, it does remind me a very real, current threat in climate change. Perhaps, this is one reason the Cosmos series was revived.

In my opinion, the threats of climate change are much more dangerous. The outcome would be the same, total destruction, but the impacts are so subtle most don’t catch the trends. Even when all factual evidence points toward environmental collapse in the mid-range future, many do not see it as imminent or requiring even short-term mitigation.

Earth. We were given a beautiful home. Let’s not blow it.

Jumping on the Carl Sagan Bandwagon (And Following the Laws of Physics)

Embarrassingly, I have to admit something. Despite my overwhelming love of science and passion for teaching science to others, I grew up not knowing whom Carl Sagan was. Back story: I grew up in East Tennessee, the son of a mechanic and a bookkeeper. I never even opened one of Sagan’s books until my 30s. I must say, it was my loss.

I have had the privilege of listening to the stories from those who knew Carl Sagan personally. He sounded like such a sweet, endearing person that the world desperately needed and unfortunately still does. By today’s standards, Sagan was a cosmic anomaly harnessing the knowledge from learning, the oration of a great leader, and the passion to spread the wonders of the universe to the masses.

Since the premier of the new production of Cosmos, listening to everyone talk of Sagan makes him sound like a god, but he was something even more great. Carl Sagan was a genuine, compassionate human being. He saw the big picture, even though it is too often clouded by politics and special interests, as what it was; our collective, solitary home among the vast cosmos. Our home has problems that must be addressed and these problems will continue to grow without intervention. Sagan knew a curious, enlightened society could be a force for change.

I wish I had known Carl Sagan, knowing how he has touched the lives of those who encountered him. Neil deGrasse Tyson has had enormous shoes to fill by assuming the role of navigator through the Cosmos. It is our turn to do our part as science communicators to ensure Sagan’s legacy rekindled is not in vain.
