Hello, Silicon Prairie. Nice Knowing You, Valley & Alley.
With Silicon Alley and Silicon Valley well-established, Jeff Slobotski believes that cities like Omaha, Des Moines and Kansas City may form the backbone of a new generation of tech start ups.
What's the Latest Development?
Entrepreneur Jeff Slobotski is hard at work making America's Great Plains the next region of technological innovation. With Silicon Alley and Silicon Valley well-established, Slobotski believes that cities like Omaha, Des Moines and Kansas City may form the backbone of a new generation of tech start ups. "What has made Silicon Valley, New York, Boston, Austin or Boulder different are not the exact same things that will make the Omaha, Des Moines and the Kansas City regions successful. If we want to change American cities, we need to start by increasing the connections in our own backyards."
What's the Big Idea?
Slobotski offers some tips for bringing together your community and concentrating resources in a way that will help entrepreneurs, investors, mentors and stakeholders: "One of the first steps we identified as being pivotal to developing and consistently building our community is to identify a community champion... If something is not being done, then it falls upon you to create the change you want to see. ... The next step in building a community is to have a distribution channel to share information through events, profiles or stories. For us this was, and continues to be, the Silicon Prairie News website."

It's one of the most consistent patterns in the unviverse. What causes it?
- Spinning discs are everywhere – just look at our solar system, the rings of Saturn, and all the spiral galaxies in the universe.
- Spinning discs are the result of two things: The force of gravity and a phenomenon in physics called the conservation of angular momentum.
- Gravity brings matter together; the closer the matter gets, the more it accelerates – much like an ice skater who spins faster and faster the closer their arms get to their body. Then, this spinning cloud collapses due to up and down and diagonal collisions that cancel each other out until the only motion they have in common is the spin – and voila: A flat disc.
It turns out, that tattoo ink can travel throughout your body and settle in lymph nodes.
In the slightly macabre experiment to find out where tattoo ink travels to in the body, French and German researchers recently used synchrotron X-ray fluorescence in four "inked" human cadavers — as well as one without. The results of their 2017 study? Some of the tattoo ink apparently settled in lymph nodes.

As the authors explain in the study — they hail from Ludwig Maximilian University of Munich, the European Synchrotron Radiation Facility, and the German Federal Institute for Risk Assessment — it would have been unethical to test this on live animals since those creatures would not be able to give permission to be tattooed.
Because of the prevalence of tattoos these days, the researchers wanted to find out if the ink could be harmful in some way.
"The increasing prevalence of tattoos provoked safety concerns with respect to particle distribution and effects inside the human body," they write.
It works like this: Since lymph nodes filter lymph, which is the fluid that carries white blood cells throughout the body in an effort to fight infections that are encountered, that is where some of the ink particles collect.

Titanium dioxide appears to be the thing that travels. It's a white tattoo ink pigment that's mixed with other colors all the time to control shades.
The study's authors will keep working on this in the meantime.
“In future experiments we will also look into the pigment and heavy metal burden of other, more distant internal organs and tissues in order to track any possible bio-distribution of tattoo ink ingredients throughout the body. The outcome of these investigations not only will be helpful in the assessment of the health risks associated with tattooing but also in the judgment of other exposures such as, e.g., the entrance of TiO2 nanoparticles present in cosmetics at the site of damaged skin."
