Court says isola... FILE - In this June 4, 2013 file photo actress Angelina Jolie arrives for the film premiere World War Z in Berlin, Germany. The Supreme Court ruled Thursday that companies cannot patent parts of naturally-occurring human genes, a decision with the potential to profoundly affect the emerging and lucrative medical and biotechnology industries. It throws out patents held by Utah-based Myriad Genetics Inc. on an increasingly popular breast cancer test brought into the public eye recently by actress Angelina Jolie’s revelation that she had a double mastectomy because of one of the genes involved in this case.

To ease shortage... Dr. Anthony Atala holds the "scaffolding" for a human kidney created by a 3-D printer in a laboratory at Wake Forest University in Winston-Salem, N.C., on Wednesday, May 8, 2013. The university is experimenting with various ways to create replacement organs for human implantation, from altering animal parts to building them from scratch with a patient's own cells.

Beyond NYC: Othe... FILE - In this Oct. 24, 2011 file photo, cars are parked on an overfly on a flooded street in Bangkok, Thailand. Sea level rise projections show Bangkok could be at risk of inundation in 100 years unless preventive measures are taken. But when the capital and its outskirts were affected in 2011 by the worst flooding in half-a century, the immediate trigger was water run-off from northern provinces, where dams failed to contain unusually heavy rains.

Court ruling may... FILE - A technician loads patient samples into a machine for testing at Myriad Genetics Friday, May 31, 2002, in Salt Lake City. DNA samples are moved from one tray to another by the eight-needle apparatus at left. The Supreme Court ruled Thursday, June 13, 2013 that Myriad Genetics Inc. cannot patent the BRCA genes, which are tested to check a woman’s risk for breast and ovarian cancer. Mutations in these genes are what led Angelina Jolie to have both her breasts removed because she had such a high cancer risk. Some experts think the court ruling may lead to lower cost testing because there could be more competition. (AP Photo/Douglas C. Pizac)

This undated handout artist rendering provided by Xijun Ni, Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences shows a reconstruction of Archicebus achilles in its natural habitat of trees. One of our earliest primate relatives was a hyperactive wide-eyed creature so small you could fit a few of them in your hand, if they would just stay still long enough, new fossil evidence shows.

Scientists project that rising sea levels would seriously damage or wipe dozens of Cuban towns off the map. Beaches would be submerged, they found, while freshwater sources would be tainted and croplands rendered infertile. (AP Photo/Franklin Reyes)
