Excerpt:<p><i>some scientists are hopeful that hyperaccumulators could be used to &quot;clean&quot; soil where there has been a build-up of toxic material due to human activity.<p>Other potential applications include phytomining - growing hyperaccumulator plants on nutrient-poor but metal-rich soils to extract the elements they take up.</i>

Here&#x27;s an informative and entertaining video that explains how the synchrotron light source works and how they use it to image things other tools can&#x27;t. <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=16028723" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=16028723</a>

It&#x27;s pretty metal to bleed metal

Why does no one ever talk about these with respect to Mars? It seems like a research-worthy pursuit to see if we can engineer plants (bacteria?) like this to modify the climate of Mars, or to make artificial superstructures self-sustaining.

Imagine doing a little genetic tinkering to produce a tree that bleeds gold or platinum.<p>Although I _am_ wondering if the three could incorporate enough metal to make increased lightning strikes a survival issue.

<i>&quot;Pycnandra acuminata is a large (up to 20m tall) rare rainforest tree, restricted to remaining patches of rainforest in New Caledonia,&quot; says Dr Antony van der Ent</i><p>If ever there was an appropriate name for a tree researcher!<p>This sounds like it could have multiple potential uses, if we can figure it out, and maybe if we can genericise it - Nickel is toxic, but its far from the only metal contaminant . If this could be adapted to, for instance, help process landfill sites, that could be big news.

Could this result in differently coloured amber? I found this [1], but it seems the colouration is due to a different mechanism not involving metals.<p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Blue_amber" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Blue_amber</a>

&gt; Other potential applications include phytomining - growing hyperaccumulator plants on nutrient-poor but metal-rich soils to extract the elements they take up.<p>Why nutrient-poor? Isn&#x27;t it enough for them to extract metal?

So is this actually metallic nickel or just nickel ions?

&gt;Its latex has an unusual blue-green colour as it contains up to 25% nickel.<p>That&#x27;s insane

Humans bleed metal too; there&#x27;s iron in haemoglobin.

Fascinating. Thanks.
