Gene therapy is a game changer for medicine — but comes with a hefty price tag


As genetic information becomes more readily available because of companies like 23andMe, scientists are finding new ways to treat diseases through gene therapy.

Modern-day tribes still carry traces of colonial devastation in their DNA


If other animals can regenerate their limbs, why can’t humans?


Modern fish and salamander genes tell us a lot about where our hands come from — and a little about why we can’t regrow them after a fight.

The (near) future of body modification


We’re much closer to genetically modifying ourselves than you think. But professor Michael Bess warns that toying with our genetics could create a divide between the modified and unmodified.

We’re toast, genetically speaking. (Well, a little bit.)


As surprising as it may seem, humans share a common genetic ancestor with yeast. Yes, yeast. Now researchers have shown that even today, some human genes swapped into a yeast cell will function identically as the yeast genes they replaced.

CRISPR is different from other gene editing techniques. It emerged from basic research into how bacteria fight off infections. Scientists realized they could use CRISPR to identify and cut apart specific DNA sequences in any cell.

A promising gene editing method causes ethical controversy


Even with good intentions and legitimate potential medical applications, gene research poses ethical debate and concern among scientists, many of whom have called for a worldwide moratorium on its use. That’s no different for a new method called CRISPR, which is splitting scientific opinion.

DNA sequences like the one pictured in this image can help predict diseases for patients and their families, but the ethics and legality of sharing that information among family members are still unformed.

When should your genetic information trump your right to privacy?


Sequencing the first human genome cost a whopping $2.7 billion; today it costs only about $1,000. But now that genomic testing a lot more accessible, are we ready to deal with the legal and ethical questions surrounding genetic information?
