God morgon!

Good morning from Sweden. This is my first post and following the current trend, it starts with some articles on the COVID19 pandemic. Today’s digest is headlined by some interesting preprints reporting inhibitors of SARS-CoV2 virus, followed by another interesting read suggesting the link between the gut microbiome and ADHD, some articles on our struggle against pathogenic bacteria, virus and fungi, and capped off with a small but informative news article on things one should not do during the COVID19 lockdown.

You might notice that today’s post is dominated by preprints. These preprints, while being an excellent way to disperse information as rapidly as it emerges, aren’t peer-reviewed. Hence, always read them with a pinch of salt!

I know a lot of my fellow researchers are unable to continue their experiments and are yearning to get back to their respective labs. It is a testing time and I believe that patience and perseverance are the biggest strengths of a researcher. So, let’s bank on our strength and hope to see each other on the other side of this global pandemic soon!

With new information emerging every day about COVID19, there is a plethora of misinformation and myths surrounding the virus and the disease. As science enthusiasts, it is pertinent for us to dispel these myths. Here is a small list that I complied a few days back. Check it out!

April 1, 2020

Hello Everyone, I am excited for my first post here. Continuing the trend the first few papers are on COVID-19 : first one talks about its classification and nomenclature. I hope everyone is staying safe and healthy. Last but not the least, keep up the hand washing.
