Year in Review ... Again

This month’s Discover includes a roundup of the top six genetics stories of 2006. Those that made the cut include an epigenetics breakthrough that could shed some light on how traits can be transmitted from parents to offspring without the requisite genes. Other stories include a team of researchers who sequenced the first complete tree genome, scientists who may have genetically engineered a healthier pig to produce omega-3 fatty acids, and a group that developed gene expression tests to help determine which chemotherapy drugs are best suited for a particular tumor.

Discover also named Jay Keasling, a chemical engineer at the University of California at Berkeley, as its scientist of the year for his groundbreaking work in synthetic biology.

Pig Organ Transplants Considered

The Wall Street Journal reports that the US Food and Drug Administration may soon allow clinical trials that involve transplanting pig organs into humans.

'Poo-Bank' Proposal

Harvard Medical School researchers suggest people should bank stool samples when they are young to transplant when they later develop age-related diseases.

Spurred to Develop Again

New Scientist reports that researchers may have uncovered why about 60 percent of in vitro fertilization embryos stop developing.
