Macrophages, derived from Greek and meaning “eating cells”, are biological cells that spring from white blood cells to destroy foreign or dying cells. They are basically cellular “policemen” that can differentiate between good and bad cells.

But some cancer cells over-express the molecular protein that macrophages recognize as friendly — they create a fake ID — which allows the cancer to avoid being perceived as foreign by macrophages. In addition, the molecules involved in the recognition mechanism appear somewhat variable from person to person, with possible links to success or failure in transplantation of stem cells.

It is generally accepted that America could immediately reduce energy consumption by at least 20% if intelligent conservation efforts were implemented at all levels. As a country, we established energy use habits decades ago when all forms of energy were relatively cheap. Lights on in high rise building at night, corridors in hotels and office buildings that are almost painfully bright, lights on in empty rooms and offices, and escalators that move even when no one is on them. This all came back to me on a recent trip to Brazil.
