Something unusual happened when Professor Andrew Sewell and the T-Cell Modulation Group at the University of Cardiff put the blood of a healthy donor in a petri dish with some cancer cells. What grew in the blood was a T-cell that no one had seen before. This T-cell attacked the cancer cells and destroyed them. Sewell and his team did what all bench...

There is a term “LD50” which is the virus dose at which fifty percent of those who are exposed, die.

We are surrounded by glass but most people don’t know the first thing about it. Glass is a strange substance: It is partly a solid and partly a liquid. What does this mean? The atoms of solids are packed close together. If they are crystalline, they are in regular, repeating patterns. The atoms in liquids are not in a regular pattern and move...

The protrusions on the Coronavirus are a group of three “S” proteins also call “Spike” proteins. These proteins bind to ACE2 receptors on the membranes of cells in the body. This has been a target of many of the over 120 vaccines that have been in production since the pandemic began. A recent intermediary report on one of the...

What is hypoxia? When you find out you will wonder why anyone would called it “happy”? Hypoxia is low blood oxygen levels. When your lungs are healthy they keep the body and your blood saturated with oxygen. Your pulse oximeter reading would be 95-100%.

In that work, one of her main concerns was reducing the number of patients that developed decubiti, or bedsores. Bedsores occur when a patient cannot move themselves and lay on the...
