Our big brain makes us superior to chimpanzees, but according to a new hypothesis, we may be paying for this size: that is the higher rate of cancer.
Fossil evidence suggests that Earth formed about 3.5 billion years ago, but the question is how long it will last and what factors can erase all life.
During dividing cells there is a random molecular process that allows some cells to self-destruct for the common good, thereby improving the condition of the surviving cells.
The 2016 Nobel Prize for Medicine was awarded to Japanese scientist Yoshinori Ohsumi for his research on cell self-destruction and regeneration mechanisms.
This new mechanism can create a breakthrough in cancer treatment - a disease that kills millions of people worldwide each year.
