Sharks Do Get Cancer Afterall, 2,500-Year-Old Antiobiotics, and Brain Cells Determine Obesity
Sharks do get cancer. Besides, digesting shark cartilage would not impart the shark’s cancer immunity if they had any.
Nubians were over-using antibiotics 2,500 years ago. They were regularly consuming tetracycline, for example, most likely in their beer.
Brain cells — not lack of willpower — determine obesity. “…a high-fat diet caused brain cells to become insulated from the body, rendering the cells unable to detect signals of fullness to stop eating.”
The science behind the insulated brain cells and obesity is interesting. Since most humans have no real predators to speak of, Darwin’s natural selection theory seems to allow the human brain to become so evolved, it becomes disassocated from the rest of the body.
The article about Nubians brewing tetracycline and using it for medicinal purposes is intriguing. Throughout much of human history, people died of infections considered non-life threatening today. Bubonic plague and tuberculosis, for example, are both bacterial infections which could presumably have been controlled by tetracycline. These two diseases killed untold millions of people in the past 2,500 years and changed the fate of nations. It’s an interesting though exercise to imagine how the world might be different had the recipe for tetracycline not been lost.
The brain cell results are for mice and rats. Are high fat diets normal for rats and mice?
Poor sharks! Getting eaten because of some silly idea about health benefits. But, on the other hand, what a brilliant marketing strategy by shark fishermen. It is in line with the whole “chicken is better for you than beef” misconception.
I’m with Virginia. If this were better known, maybe the Asians would quit killing the sharks.
