In the News: Synthetic Genomes, Gene Drives, and Human-Pig Chimeras

  A number of developments in the past few weeks brought to the forefront various issues related to the ethical and social implications of novel genetic technologies, public engagement in science, and democratic deliberation about controversial research. On June 2nd, a … Continue reading

In the news: First optogenetics trial in humans to go ahead

You might have caught the reference to something called “optogenetics” in a January episode of the hit CBS series Limitless. Next month, a clinical trial in Texas will test whether optogenetics can restore vision to individuals with the degenerative disease retinitis pigmentosa. … Continue reading

In the news: Error in study of ancient African genome led to incorrect conclu...

A few months ago we blogged about the publication of the first genome sequence from an ancient African, in which the authors concluded that an ancient “back migration” of humans from the Middle East into Africa had left traces of … Continue reading

In the news: Gene drive-based control of disease-carrying mosquitoes edges cl...

Two studies published in the past month marked significant advances in the potential for using gene drives to curb the spread of infectious diseases by targeting their insect carriers. A gene drive is a genetic system that allows a genetic … Continue reading

What is a gene drive?

A gene drive is a genetic engineering technique that efficiently “drives” an introduced DNA sequence to become inherited by all its offspring.  There is great interest in gene drives with the advent of CRISPR technologies, which simplify some of the technical aspects … Continue reading

In the news: Ancient African genome tells complex story of human genetic hist...

The first genome sequence of an ancient human from Africa was published earlier this month in the journal Science, shedding light on our species’s complex history of migration and genetic mixing. (“First ancient African genome reveals vast Eurasian migration,” Nature) In … Continue reading
