St. Jude study offers new hope for children with kidney tumors deemed inoperable

Physicians at St. Jude Children's Research Hospital have demonstrated that children with bilateral Wilms tumor, a cancer of the kidneys, can retain normal function in both kidneys by undergoing a procedure called bilateral nephron-sparing surgery, even when preoperative scans suggest that the tumors are inoperable.

Too much information? Study shows how ignorance can be influential

In the current issue of The RAND Journal of Economics, USC researchers provide a challenge to the classic economic model of information manipulation, in which knowing more than anybody else is the key to influence.
