Every second your body produces 2.5 million red blood cells. Which means that each day your body produces around 200 billion red blood cells. On top of that, your body creates billions of white blood cells and around 400 billion platelets per day (platelets...
As we age, senescent cells arise everywhere in our body. Senescent cells are cells that are damaged but refuse to die. Despite their damage, and their malfunctioning, they keep lingering on. Some scientists call them “zombie” cells, because they normally should...
During aging, our tissues become crosslinked. Crosslinks are connections (“links”) formed between the building blocks that make up our tissues. For example, sugar molecules are able to form crosslinks between proteins like collagen, which is an important...
Telomeres are the “caps” on our DNA which protect our DNA. Just like shoestrings have plastic caps to protect them from unraveling, our DNA strands have telomeres that protect them against unraveling. Telomeres are made of DNA themselves. But this DNA does not...
We are living in fascinating times. Scientists are developing completely novel tools to impact the molecular machinery of our cells far more precisely, faster and more cheaply than ever before. What are some of these promising developments? 1. Gene editing...
