Yale Team Finds Order Amidst the Chaos Within the Human Genome; Mom and Dad’s Contributions Counted and Fossil DNA Not Dead After All

The Encyclopedia of DNA Elements (ENCODE) project is the effort of hundreds of scientists to describe the workings of the human genome. Their research, outlined in 30 papers published in multiple journals Sept. 5, has confirmed our genome is far more complex than originally thought.  Regions that contain instructions for making proteins, which carry out life’s functions, account for only about 1 percent of our genome. ENCODE has shed light on the other 99%. Almost 80 percent of the genome is biochemically active, much of it involved in some sort of regulation of genes. Vast regions of our DNA once considered “junk” contain some 400,000 regulators called enhancers, which play a key role activating or silencing genes despite residing far away from the gene itself. Yale University researchers played a key role ENCODE, helping to author 9 of the 30 papers published in four journals on Sept. 5. Some of their work is described below.

The massive Encyclopedia of DNA Elements (ENCODE) unveiled Sept. 5 reveals a human genome vastly more rich and complex than envisioned even a decade ago. In a key supporting paper published in the journal Nature, the lab of Yale’s Mark Gerstein, the Albert L. Williams Professor of Biomedical Informatics, has found order amidst the seeming chaos of trillions of potential molecular interactions. (more…)

UD professor reports milestone in fuel cell membrane research

It looks like a plastic candy wrapper that’s been charred on both sides, but it may hold the solution to commercially viable fuel cells.

About the thickness of a human hair, it is actually a thin polymer membrane sandwiched between two catalysts. The work is that of Yushan Yan, Distinguished Professor of Engineering at the University of Delaware, who is known for developing new catalysts and membranes to reduce the cost and improve the durability of fuel cells.

The membrane, he says, is a game changing development that shows great promise to revolutionize the way engineers and scientists think about traditional chemical crosslinking methods used to create strong fuel cell membranes. (more…)
