Returning to science: Navigating the facts in an age of misinformation

Science is by nature evidence-based. Prior to publication, hypotheses are tested and results scrutinised. This process is designed to ensure accuracy and reliability.

The Covid pandemic was the first time I became interested in this newspaper. That period was marked by fear and uncertainty. This environment was conducive to pseudo-sciences and misinformation. A world leader even suggested that Covid-infected people might be cured by taking bleach. The science behind the development of vaccines is complex and elegant, but I admit that it’s difficult for people without a background in science to understand.

From a scientific perspective, similar proposals, such as disinfecting the sun loungers along our beaches, were misguided, and wasted time and resources. Covid virus is rendered inactive by ultraviolet light, and ineffective at warm temperatures like those in our area. At the time this was not well understood and the public often discussed “killing” the viruses in the same manner as we kill bacteria. As a virus does not have a life, it can’t be killed. It would take a long time to fully explain and justify that statement, which shows the difficulty faced by policymakers when they must make decisions on scientific principles they do not fully understand.

I will be exploring some of the most interesting medical developments and explaining the science behind them using a clear, accessible language in the coming months. I want to give you the context that will help you form your own opinions. I will also discuss common health problems that many of us face, such as high blood pressure, heart diseases, and seasonal flu, and how you can stay healthy.

Newspapers employ editors, whose job it is to make sure that content published is fair, accurate and balanced. Unfortunately, these standards don’t apply to the large number of content creators and influencers who are able to disseminate “truths” and facts on the internet without oversight.

This is why I am so happy to be back. Please feel free to suggest topics for me to write about. I’m unable to answer medical questions individually due to ethical and legal reasons. Simply contact me at medicalmatterseuroweekly@gmail.com, and I will take it from there.

I wish you a happy and healthy 2026.

Dr Marcus Stephan
