Scientists have decoded the first detailed images of those spikes in their natural state, while still attached to the virus using cryogenic electron microscopy (cryo-EM) and computation techniques as per a study published in the journal Quarterly Reviews Biophysics Discovery. This serves as the critical step in designing therapeutic drugs and vaccines against the vi...

COVID-19 Causes Brain Storm Emerging shreds of evidence shed light on the role of COVID-19, causing cognitive effects, such as brain fog, and fatigue. The spike protein of the SARS-CoV-2 virus often called the S1 protein - depicted as the red arms of the virus, crosses the blood-brain barrier in mice and enters the brain, causing them to release cytokines and inflammatory products, as per a study published in the journal Nature Neuroscience. The spike protein is responsible for dictating which cells the virus can enter. These binding proteins by themselves can cause damage to the cells a...
