...ed the expression of a protein known as VEGF. VEGF fuels tumor growth by spurring the development of blood vessels in cancer cells that might otherwise die. Normally, the immune system can kill off small tumors. However, when they grow large enough the body can no longer fight off the tumor cells.

...nes and reactants in an energy-making process that fuels most cells. "Magnesium ions are essential to the stability of several different critical processes and structures in the cell, so there has to be a fairly intricate set of regulators to maintain consistent levels of it," says senior investigator Edu...Nature can help reduce greenhouse gas, but only to a point

... as a consequence of the large-scale use of fossil fuels in the industrial era. This has apparently brought about a stronger relative increase in the light carbon isotope 12C. Due to this the ratio of the stable carbon isotopes 13C/12C has show a clearly measurable decrease of 0.1%.
