The St. Louis Zoo showcased new plans for the 13 and a half acre expansion on the southern side of interstate 64.

The plans aren’t set in stone, and the zoo is still asking for public opinion.

But it outlines a framework of where the zoo could go in the next 20 years – adding exhibits, a hotel, an upscale restaurant.

Ed Uhlir is a consultant on the expansion project, and says moving parking and adding a way for visitors to cross the interstate has to be the first move.

In separate studies both published today, researchers at Washington University mapped the genomes of two types of cancer: endometrial cancer, and acute myeloid leukemia.

Both studies are part of The Cancer Genome Atlas project, an effort funded by the National Institutes of Health to study the genetic basis of 20 major human cancers.
