This Luxurious Yarn Is Made From Bones, Ligaments and Tendons

It’s people!  They really should name the product “soylent wool” 😀

Wendelin Stark would like a new sweater. It’s cold in Zürich, where he lives, so he’d like a really warm one. Preferably one as cozy as cashmere.

Before long, Stark may be wearing one of his own invention, crafted with an ultra-soft wool-like yarn spun from all the stuff that’s left after an animal’s been slaughtered and processed. His team at the Functional Materials Laboratory at ETH Zürich, where he’s a professor, has spent four years creating such a fabric, and recently created a working prototype—of a mitten.

My preferred use for animal by-products is petroleum production.  There was news years ago about someone who’d pioneered a contraption to produce petroleum/oil from chicken carcasses, wanting to employ them near chicken farms.  I doubt it would be enough volume to fuel vehicles, but given the hurdles that the gelatin wool still has to address – petroleum production for textiles that already work would be a better use of resources to me.  We are more dependent on petroleum products than we’d like to admit.

Studies: Bones Weak, Forecast Calls for Increasing Fractures, Breaks, and Osteoporosis.

It’s another angle on the attack against our increasingly sedentary lifestyle:

Somewhere in a dense forest of ash and elm trees, a hunter readies his spear for the kill. He hurls his stone-tipped weapon at his prey, an unsuspecting white-tailed deer he has tracked since morning. The crude projectile pierces the animal’s hide, killing it and giving the hunter food to bring back to his family many miles away. Such was survival circa 5,000 B.C. in ancient North America.

But today, the average person barely has to lift a finger, let alone throw a spear to quell their appetite. The next meal is a mere online order away. And according to anthropologists, this convenient, sedentary way of life is making bones weak. Ahead, there’s a future of fractures, breaks, and osteoporosis. But for some anthropologists, the key to preventing aches in bones is by better understanding the skeletons of our hunter-gatherer ancestors.

It is amazing how researchers are able to ignore results from other fields. We know that bone density is not a good predictor for fractures. On the other hand, we know that dairy product consumption is correlated with higher density and fractures.  There is no consensus on how to explain that currently, but one interesting theory is that dairy products promote bone metabolism (hence the higher density) up to renewal exhaustion (hence the fractures).  I’d be interested to see how the theory holds up when they compare bone details between those who are and are not lactose intolerant.  It wouldn’t be hard, considering that an estimated 75% of the world’s population is lactose intolerant.

The diet of the forager doesn’t appear to have been considered either.  Calcium and vitamin K are not found in meat 😉

Individuals who are vitamin K deficient have repeatedly been shown to have a greater risk of fracture. In addition, for women who have passed through menopause and have started to experience unwanted bone loss, vitamin K has clearly been shown to help prevent future fractures.

Vitamin K is not evil – it’s in our best interest to balance intake with blood thinners.
