Researchers' findings that signaling proteins within cells are implicated in cancer, heart disease and diabetes. The work could lead to new drugs that would block the action of those proteins to treat disease. NASA's NEAR Shoemaker spacecraft, which became the first probe to slip into the orbit of an asteroid. The spacecraft has circled the 21-mile wide Eros asteroid for six months, unlocking chemical secrets of some of the most primitive material in the solar system. Advances in the bizarre world of quantum research, which have led to discoveries of electrical fields and motions that may help develop new types of computers and electrical circuitry.
