DNA mutations happen all the time in the body, but the immune system usually detects and deals with them. When the system fails, cancer results. Yet some animals, such as elephants, almost never get cancer, and scientists have learned that the elephant DNA repair system is 20 times more powerful than the human system.
Lupus results when the immune system turns on the body, producing inflammatory attacks on virtually any organ. A minority of patients have lupus only on the skin, and while this is not life threatening, it can still be psychologically devastating.
Synopsis: Multitasking seems like a necessity for most people, and most of us think it inproves our efficiency. However, studies show that only a tiny proportion of people can juggle tasks well. Researchers discuss why our brains can’t do two things at once, and why “supertaskers” may be different.
