This sidebar was fact-checked by Manolya Sag. Viruses, with their large numbers and fast replication time, are always evolving. For the RNA virus SARS-CoV-2, mutations are constantly occurring during its replication. In fact, it has been estimated by the COVID-19 Genomics UK Consortium that approximately 4000 mutations have arisen in the virus’ spike protein alone. … Continue reading The UK Variant: What We Know and What We Don’t
The hidden war between viruses and host cells has influenced the evolution of all life on earth. For millions of years, viruses have acquired and refined weapons to undermine cell defenses and redirect cellular processes to the task of viral replication. Surviving cells created defenses to stave off initial attacks and “remember” attacks, so more … Continue reading Hide-and-seek: how SARS-CoV-2 hides from our immune system

Our sense organs were sculpted by natural selection to help us survive in what the evolutionary biologist Richard Dawkins calls Middle World. He is quick to distinguish this from the J. R. R. Tolkien’s land of hobbits and … Continue reading Overcoming Middle World

Author’s Note The COVID-19 pandemic has created unprecedented challenges for our healthcare heroes. As the on-going pandemic continues, many of our healthcare heroes are continually risking their lives to help fight the battle. I personally wanted to celebrate our healthcare heroes by highlighting research that describes the experiences of healthcare professionals. Thus, I hope this … Continue reading Sidebar: Healthcare Heroes in Wuhan, China
Before we launch into the video, we should first define the term “Divergent Evolution,” which Demitri defines as: When at least 2 groups of the same species that originate from the same parent species independently acquire differences that are necessary for persistence in their respective environments. You can find out more about divergent evolution here. … Continue reading Video Sidebar: Wrapping up- Where Did SARS-CoV-2 come from?
