Overcoming cardiac pacemaker "source-sink mismatch"

Instead of complication-prone electronic cardiac pacemakers, biomedical engineers at Georgia Tech and Emory envision the creation of “biological Read more

Hope Clinic part of push to optimize HIV vaccine components

Ten years ago, the results of the RV144 trial– conducted in Thailand with the help of the US Army -- re-energized the HIV vaccine field, which had been down in the Read more

Invasive cancer cells marked by distinctive mutations

What does it take to be a leader – of cancer cells? Adam Marcus and colleagues at Winship Cancer Institute are back, with an analysis of mutations that drive metastatic behavior among groups of lung cancer cells. The findings were published this week on the cover of Journal of Cell Science, and suggest pharmacological strategies to intervene against or prevent metastasis. Marcus and former graduate student Jessica Konen previously developed a technique for selectively labeling “leader” Read more

A few links for BEINGS2015

Several well-known authors, scientists and bioethicists are in downtown Atlanta’s Tabernacle for the #BEINGS2015 conference. Paul Wolpe and the Center for Ethics have been central to organizing the event, and several Emory biomedical and genetics researchers will be involved in shaping the consensus documents that will emerge.

I won’t attempt to summarize the ongoing discussion at this point; with biotechnology, it is difficult to draw a circle around certain topics and say “we’re going to focus on this, but not this” and today was a good example. The border between existing agricultural biotechnology and new organisms seems hard to define.

Three interesting relevant links:

The National Academy of Sciences is launching an effort to guide decision making on human gene editing technologies such as Cas9/CRISPR

Collection of scientists’ comments on human gene editing and Cas9/CRISPR in Nature Biotechnology

Nature Chem Bio paper on engineered yeast that “paves way for home brew heroin”. Interesting role of FBI in overseeing this emerging area, and note that full production of opiates in yeast may look close, but is still not yet possible.
