Here'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't. https://news.ycombinator.com/item?id=16028723

Excerpt:

some scientists are hopeful that hyperaccumulators could be used to "clean" soil where there has been a build-up of toxic material due to human activity.

Other potential applications include phytomining - growing hyperaccumulator plants on nutrient-poor but metal-rich soils to extract the elements they take up.

It's pretty normal to bleed metal, since blood has iron.

Also, chlorophyll (what makes plants green) contains magnesium , which is a metal. "Mag wheels" are named after magnesium.

So is this actually metallic nickel or just nickel ions?

Yeah it would be for the short time you manage to do that.

"The term heavy metal refers to any metallic chemical element that has a relatively high density and is toxic or poisonous at low concentrations. Examples of heavy metals include mercury (Hg), cadmium (Cd), arsenic (As), chromium (Cr), thallium (Tl), and lead (Pb).

Slang, adjective. Loosely equivalent to "awesome" or "cool" or "legit", especially to fans of heavy metal music.
