Science will most likely advance to a point where all diseases will have a cure of some sort. However society will have to go through some massive changes before it will happen. These changes will have to be in our character on a basic and...
Do we use only Ten Percent of our Brains
By: Stephanie Andrews - 447415

Cells involved in human immunity
By: Tami Port MS
The human immune system is composed of three lines of defense, each with different barriers, cells and chemicals that protect us from infection. The second line of immune defense is nonspecific, meaning that it does not target specific pathogens (microbes that cause disease), but instead...

By: Mark Frigerio
If evolution has taught us anything, it is that favourable survival characteristics are perpetuated and non-favourable characteristics are eradicated. Applying this to the development of 21st century humans, it has been well documented that our progression from the earliest ancestral hominoid beginnings of homo habilis...

There will likely never be a single cure for cancer. If medical science does cure cancer at some time in the future there will be dozens of treatments - effective against different types of cancer.Firstly, we need to think about how cancer develops. Each...
Nonspecific immune system defenses
By: Tami Port MS
