As the year comes to a conclusion I look around and see and hear the voices of uncertainty and fear all over the media. The winds of turmoil blow throughout the Middle East, Africa, Europe and Asia – and even in our own city streets. Friction boils over between those attempting to keep the peace and those who see those authorities as impediments to their freedom. Battles of words and actions wage on racial fronts, political fronts, religious fronts and societal fronts. And people face financial, health and other day-to-day challenges.
So often science and technology too has taken a bad rap in Christian circles – and often rightly so. For in times past many in academia and intelligentsia have misused and abused these God-given blessings to try and disprove even the existence of the Creator and His authority in the earth. But in 2014, I believe scientific and technological advancements as a whole reflected some of the most positive steps forward that we’ll be able to look back on with pride in the years to come.
That’s not saying that even in 2014 there haven’t been moments of imperfection in the scientific community. In fact a popular scientific journal even acknowledges that the current pressure on researchers to “publish or perish” has often yielded reports of new discoveries that had to subsequently be retracted for any number of reasons. See five such examples at the referenced site: http://www.livescience.com/49266-retracted-science-papers-2014.html.
Sometimes the claims and results proved merely to be silly, though harmless – other times the sacrifice in the integrity of the scientific method yielded dangerous and lethal results. Take for example the now well-refuted claim that there was scientific evidence linking the measles-mumps-rubella (MMR) vaccine to autism, and that the CDC was covering it up. The sources’ published papers were later found to be based on “falsified data and weak statistics.” Though their claims were subsequently retracted, the rumors generated by the publications didn’t go away. And we’re seeing the results in many cases of kids still being exposed unnecessarily to these dangerous and potentially deadly diseases.
But for every one of these cases of sloppy science, 2014 has seen ten positive ones that have either already benefitted mankind, or will very likely do so in the near future. This is true across the entire spectrum of scientific research and development: whether we’re looking at archaeology, astronomy and cosmology, biology and genetics, chemistry and physics, earth science and geology, even space exploration. While I’m fascinated by the achievements made in each of these areas over the past twelve months, for the sake of space and time I’d like to focus on one that touches each of our lives – namely advances made in medical and health science. My hope is that it will lift your spirits as we enter into the New Year.
