Here’s a good riddle for you:
Many epidemiological studies have suggested that coffee/caffeine consumption reduces one’s risk of developing Parkinson’s. Study after study has suggested that drinking coffee is beneficial.
Recently, however, Japanese researchers have discovered something really curious: people with Parkinson’s have reduced levels of caffeine in their blood compared to healthy controls… even when they have consumed the same amount of coffee. (???)
In today’s post we will look at what coffee is, review the results of this study, and try to understand what is going on.

Legend has it that in 800AD, a young Ethiopian goat herder named Kaldi noticed that his animals were “dancing”.
They had been eating some berries from a tree that Kaldi did not recognise, but being a plucky young fellow – and being fascinated by the merry behaviour of his four-legged friends – Kaldi naturally decided to eat some of the berries for himself.
The result: He became “the happiest herder in happy Arabia” (Source).
This amusing encounter was apparently how humans discovered coffee. It is most likely a fiction as the earliest credible accounts of coffee-consumption emerge from the 15th century in the Sufi shrines of Yemen, but since then coffee has gone on to become one of the most popular drinks in the world.
Silly question, but what exactly is coffee?
Today’s (experimental) post provides something new – an overview of some of the major bits of Parkinson’s-related research that were made available in January 2018.
In January of 2018, the world was rocked by news that New Zealand had become the 11th country in the world to put a rocket into orbit (no really, I’m serious. Not kidding here – Click here to read more). Firmly cementing their place in the rankings of world superpowers. In addition, they became only the second country to have a prime minister get pregnant during their term in office (in this case just 3 months into her term in office – Click here to read more about this).
In major research news, NASA and NOAA announced that 2017 was the hottest year on record globally (without an El Niño), and among the top three hottest years overall (Click here for more on this), and scientists in China reported in the journal Cell that they had created the first monkey clones, named Zhong Zhong and Hua Hua (Click here for that news)

As the age of personalised medicine approaches, innovative researchers are rethinking the way we conduct clinical studies. “Rethinking” in radical ways – think: individualised clinical trials!
One obvious question is: Can you really conduct a clinical trial involving just one participant?
In this post, we will look at some of the ideas and evaluate the strengths and weaknesses these approaches.

In the annals of Nobel prize history, there are a couple winners that stands out for their shear….um, well,…audacity.
One example in particular, was the award given to physician Dr Werner Forssmann. In 1956, Andre Cournand, Dickinson Richards and Forssmann were awarded the Nobel Prize in Physiology or Medicine “for their discoveries concerning heart catheterisation and pathological changes in the circulatory system”. Forssmann was responsible for the first part (heart catheterisation).
In 1929, at the age of 25, Forssmann performed the first human cardiac catheterisation – that is a procedure that involves inserting a thin, flexible tube directly into the heart via an artery (usually in the arm, leg or neck). It is a very common procedure performed on a daily basis in any hospital today. But in 1929, it was revolutionary. And the audacious aspect of this feat was that Forssmann performed the procedure on himself!
And if you think that is too crazy to be true, please read on.
But be warned: this particular story gets really bonkers.
