DELETING THE ZOMBIE SENESCENT CELLS IN OLD TISSUES. Thanks to the primordial survival circuit we've inherited from our ancestors, our cells eventually lose their identities and cease to divide, in some cases sitting in our tissues for decades. Zombie cells secrete factors that accelerate cancer, inflammation, and help turn other cells into zombies. Senescent cells are hard to reverse aging in, so the best thing to do is to kill them off. Drugs called senolytics are in development to do just that, and they could rapidly rejuvenate us.

And it is home to what is arguably the most prestigious national scientific association in the world, the Royal Society. Founded in the 1600s during the Age of Enlightenment and formerly headed by Australia's catalyst, the botanist Sir Joseph Banks, as well as such legendary minds as Sir Isaac Newton and Thomas Henry Huxley, the society's cheeky motto is a pretty good one to live by: "Nullius in Verba," it says underneath the society's coat of arms. That's Latin for "Take nobody's word for it."

Aging, quite simply, is a loss of information.
