 : Human gene editing is here, and scientists have a new tool that makes it easy.
</p>
<p>
 It's called CRISPR—a mini sharpshooting assassin.
</p>
<p>
 CRISPR is made of two parts: A piece of RNA that acts as a guidance system and an enzyme.
</p>
<p>
 Inside a cell nucleus, CRISPR's guidance system hunts for a specific DNA sequence, like a problematic gene.
</p>
<p>
 When CRISPR finds its target (a section of DNA that matches the guide RNA), CRISPR clamps onto that DNA and slices it.
</p>
<p>
 When the cell tries to repair the damage, it uses an engineered, healthy part of the gene to fix it.
</p>
<p>
 This editing tool isn't perfect yet. But it is powerful. So now is the time to ask—when and how should it be used?

<p>Colossal explosions shake a remote corner of the Siberian tundra, leaving behind massive craters. In Alaska, a huge lake erupts with bubbles of inflammable gas. Scientists are discovering that these mystifying phenomena add up to a ticking time bomb, as long-frozen permafrost melts and releases vast amounts of methane, a potent greenhouse gas. What are the implications of these dramatic developments in the Arctic? Scientists and local communities alike are struggling to grasp the scale of the methane threat and what it means for our climate future. <b>(Premiered February 2, 2022)</b></p>

<p>In the Arctic, enormous releases of methane, a potent greenhouse gas, threaten the climate.</p>

<p>Scientists have cured a handful of people of HIV by piggybacking on treatments they received for blood cancer. But does that bring a widespread cure any closer?</p>
