J Craig Venter sequenced the human genome. Now he wants to covert DNA into a digital signal

J Craig Venter sequenced the human genome. Now he wants to covert DNA into a digital signal | Mount Library | Scoop.it

J Craig Venter has been a molecular-biology pioneer for two decades. After developing expressed sequence tags in the 90s, he led the private effort to map the human genome, publishing the results in 2001. In 2010 the J Craig Venter Institute manufactured the entire genome of a bacterium, creating the first synthetic organism.
Now Venter, author of Life at the Speed of Light: From the Double Helix to the Dawn of Digital Life, explains the coming era of discovery.

Healing Damaged Hearts With Stem Cell Implants Gets New Technique

Healing Damaged Hearts With Stem Cell Implants Gets New Technique | Mount Library | Scoop.it

We’re much better at saving the lives of those who suffer a heart attack these days. Sadly, many people survive a heart attack only to later succumb to heart failure from the damage it caused. Modern methods help heal the heart somewhat after a heart attack, but cardiologists think stem cell therapy might one day offer a far superior alternative.
Stem cells aren’t just good for growing new organs, they can also heal old or damaged ones from the inside. Thousands of patients whose hearts were damaged in a heart attack have undergone some form of stem cell therapy worldwide, and the results are promising. But there’s a problem. Once in the heart, the cells don’t tend to stay put.
Dr. W. Robert Taylor, professor of medicine at Emory and Georgia Tech and director of Emory’s cardiology division, recently co-authored a paper on a new technique that may significantly increase the efficacy of stem cell therapy in the heart.
