Doc Clark was given a box of rocks when she was four and it all went downhill from there. Having made the mistake of going to engineering school, she took a geology class, realized she was on the wrong path through life and jumped ship for a degree in rocks. She's done lots of things over a lifetime, including mapping geothermal resources and Yellowstone-related volcanism, investigating the oil deposit under the Great Salt Lake and managing the field work of a Superfund site.

Fukuchima Daiiachi Berellium-7

Fukuchima Daiiachi Berellium-7

I’ve had the nasty flu that’s been going around so today’s post will be short. Today’s post is about beryllium-7, which is a proxy for measuring radioactive fallout. BERYLLIUM-7 AFTER THE FUKUSHIMA MELTDOWN One day, I started playing with data for airborne radioisotopes before and after the Fukushima Daiichi Nuclear Power Plant meltdowns. Why? Because I was sick and tired of looking at faked Fukushima data on the internet. It was and still is fake data that’s designed to scare and…

Medical Marijuana: Current Scientific Basis 2018 – Part II

This is Part II of a two-part series on medical marijuana. In Part I last week, we surveyed just what the term medical marijuana means.

This week, we will look at the results of actual scientific studies into the drug and health effects of marijuana. I’m not pulling any punches today. I will warn you now that…

Medical Marijuana: Current Scientific Basis 2018 – Part I

Medical Marijuana: Current Scientific Basis 2018 – Part I

WHAT IS MEDICAL MARIJUANA? That might be a moot question in a place like California, but I don’t live in a blue state. I live in a red state without laws that legalize medical marijuana. Because some of my regular audience lives where I do, we’ll first define some terms and explain some concepts. I find that a lot of conservative-state folks are not familiar with what the medical marijuana thing is really about. This is part one of a…

Green Eggs, No Ham

COLOR AFFECTS YOUR MIND It’s been known for quite a while that colors affect your mind and emotional state at the subconscious level.  Reds, yellow and oranges have a cheering effect on you while blues, greens and purples have a calming effect but they can also make you feel sad.

Your Brain Sneezes

Your Brain Sneezes

It happens to everyone: some stimulus triggers the trigeminal nerve bundle, which in turn signals the sneeze center of the lateral medulla of the brain stem. The nervous functions of the brain stem are the most basic and powerful in the body so once the sneeze center has been stimulated, the rest of the sneeze reflex is unavoidable. Instructions are sent from the brain stem to the lungs to suck in air. The glotis – the opening at the top…

You Put What on Your Face?

This is the daily short science blog for the Merry Blogmas 2017 campaign. I will happy when it’s over. Even with decreased or no citations, daily blogging is a bit much. | Today’s post is a ramble about the science and pseudoscience of clay-based facial skin treatment.

The Roach-Killer Rock

This is the daily Merry Blogmas 2017 short science post for December 17. 2017. | Today’s topic is boric acid. THERE ARE NO BORIC ACID MINES Seriously, I really should have saved this up for my other blog but this blog is on a schedule. Thus it gets priority these days. I was calmly surfing the net, looking at do-it-yourself recipes using borax, when I came across a site that I refuse to mention here. This unmentionable site not only recommended…
