Scientists can fool poachers by making fake rhino horns out of horse hair – BGR

Rhinos have been hunted and killed for their horns for so long that many species are teetering on the brink of extinction. Some subspecies, such as those of the black rhino, are extinct in areas where they once thrived and nearly extinct in others. The situation is incredibly dire and conservation efforts need not be as effective as one might hope, but science may be able to come up with a solution.

In a new paper published in Scientific Reports, researchers explain how they manufactured fake rhino horn using horse hair. The fake horn is similar in look and feel to the real thing, and even the chemical composition of the fake horn is similar to an actual horn. This could change everything.

Poachers hunt rhinos because of the incredibly high demand for horns. Rhino horn is used in some cultures as a medicinal ingredient, while others favor the horn as a sculpting material. The demand is so high that the horn is quite literally worth its weight in gold.

Regardless of what some cultures believe, rhino horn is actually all that special, and made of the same kinds of material that forms hair. With that in mind, scientists have selected horse hair as a substitute and have developed a method to back the hair tightly together. The resulting structure is rigid, like a real horn, and even microscopic inspection reveals it to be very similar.

In the image above, A and C are the real horn, while B and D are the horse hair. The faux horn could be used in all the same ways as the real thing, and it would be extremely difficult for anyone without their scientific tools at their disposal to tell the difference.

The idea here is to affix fake horns to rhinos, of course, but rather to flood the black market with copies of horns that are so close to the real thing that nobody will know one another. With such an insane demand for rhino horn and the completely unregulated market within which it is distributed, adding fake horns to the mix would seem trivial.

If enough fake horns could be produced, prices would start to fall, reducing the payoff for poachers. Eventually, the risks of poaching such animals would begin to outweigh the monetary reward and, ideally, the entire enterprise would collapse. Need the hope, anyway.

"It appears from our investigation that it is rather easy as well as cheap to make bio-inspired horn-like material that mimics the rhino's extravagantly expensive tuft of nose hair," the scientists explain.

“We leave it to others to try to take our technology further and perhaps even go so far as to fool the punters into buying it or indeed preferring the real, and extremely expensive, rhino horn. Whether flooding the market with confusing horn copies will ultimately lead to saving rhinos roaming in the wild remains to be seen. ”
