PRESS RELEASE- Australian scientists have found that the bacterium Cupriavidus metallidurans catalyses the biomineralisation of gold by transforming toxic gold compounds to their metallic form using active cellular mechanism.

This is the first direct evidence that bacteria are actively involved in the cycling of rare and precious metals, such as gold. These results open the doors to the production of biosensors: “The discovery of an Au-specific operon means that we can now start to develop gold-specific biosensors, which will help mineral explorers to find new gold deposits. To achieve this we need to further characterize the gold-specific operon on a genomic as well as proteomic level. If funding for this research is granted I believe we can produce a functioning biosensor within three to five years”, concludes Reith.

in other words, figure out how it works?

I must confess that the lingo put a strainium in my cranium. Nonetheless, I got the general idea.
Woah... so there really is a gold bug.
Yeah, and now I want to know how to grow my own gold.
I wonder what you feed them...
Whatever they want. ;-)
LOL... well, sure...
Though if it’s platinum the trade-off might not work out. :-)
To simplify things, look it it like this:
The angular dependence of the nuclear quadrupole resonance (NQR) signal intensity emitted from polycrystalline hexamethylenetetramine has been analytically investigated for all directions for non-contact detection of chemicals by nuclear quadrupole resonance. High-pressure Raman spectroscopic measurements have been carried out on hexamethylenetetramine (C6N4H12) up to pressures of 20 GPa. The evolution of Raman spectra at high pressures shows that the system undergoes two structural transitions around 1.4 and 12.5 GPa. The second phase transition around 12.5 GPa is associated with a large hysteresis indicating the first-order nature of the transition. Excessive broadening accompanied by considerable decrease in intensity of the internal modes above 15 GPa suggests that the system could be disordered above this pressure. The field pattern of the NQR signal from a column sample was measured. The emitted patterns were the same as that from a united single magnetic dipole, which fitted well to the estimation based on quadrupole principle axis system. This result is helpful to design an antenna for NQR remote detection.
Those noodle salesmen are the worse.
you sure thats the same article? this verbiage describes nucular detection of chemicals.
i’m sure the authors get points for creative use of jargon
and maximizing number of syllables.

Y’know, if these geniuses could come up with a bacteria that could transmute lead *into* gold, they’d have a surefire product.
Thanks decimon.
Sarcasm is unbecoming. ;-)
Duran Duran was a metal group?
What’d I do? What’d I do?
:’)
Hey, *someone* put “gold bugs” in the title, and I swear it wasn’t me. :’)
" If funding for this research is granted I believe we can produce a functioning biosensor within three to five years”,.....
Thanks for the ping. Fascinating.
