We’re One Step Closer to Being Able to Regrow a Lost Tooth

We’re one step closer to being able to regrow a lost tooth, thanks to a new study showing it’s possible to grow multiple teeth from a single root. These teeth can then be implanted to become fully functional. Thus far it has only been tested in rats, but it could lead to a potential revolution in human dental care.

Why this over an implant?  Dentures are notorious for not staying seated, and the fit might not be that great to begin with.  A natural tooth would discolour, while implants are less likely.  Getting “full functionality” also means the ability to have another root canal 😉

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.

The Genetics of Being Injury-Prone

Injury is a fact of life for most athletes, but some professionals—and some weekend warriors, for that matter—just seem more injury-prone than others. But what is it about their bodies that makes the bones, tendons, and ligaments so much more likely to tear or strain—bad luck, or just poor preparation?

A growing body of research suggests another answer: that genetic makeup may play an important role in injury risk.

…the largest market for sports-injury genetic testing may be the general public. A growing number of companies like 23andMe, Pathway Genomics, DNAFit, and Stanford Sports Genetics offer genetic tests that can tell the average consumer about his or her risk for sports injuries, including ACL ruptures, stress fractures, osteoarthritis, and spinal-disc degeneration.

On some levels, it’s no different than testing your VO2 max.  But there’s also the potential that genetic testing can be used against, like medical/health insurance.

At the end of the day, should the knowledge that your ligaments and tendons are more susceptible to injury than others?  I think not.

Vitamin C helps the body produce and repair collagen.  Oranges are high in vitamin C, and low in vitamin K.  Grapefruit is not recommended for medications in general – the “grapefruit effect” is well known.

Sports Massage Doesn’t Flush Toxins, but May Help You Recover

There is good reason massage therapists are part of an elite runner’s entourage. And why the lines for a postrace massage seemingly extend for miles. A rubdown—even a deep, intense one—feels great. Runners report that massages help lessen muscle tension and improve range of motion, while also making them feel relaxed and rewarded for their hard efforts.

Yet despite massage’s popularity and positive reputation, there’s been little scientific evidence to support why athletes feel so good when they hop off the table. “It can be hard to merge basic science with alternative medicine,” says Justin Crane, Ph.D., a McMaster University researcher who conducted some of the first objective studies on massage in 2012. Practitioners say massage relieves muscle soreness, promotes circulation, flushes toxins and lactic acid from the body, and eases joint strain—claims supported by centuries of anecdotal evidence from China, Sweden, and around the globe. But science hadn’t confirmed just what massage actually achieves—until now. Recent research has sorted out what’s true and what’s not.

Massage do not flush lactic acid, or other “toxins” from your muscles. Lactic acid is produced during exercise, and though you might associate it with a burning feeling during hard work – it’s not a problem, isn’t responsible for next-day soreness, and doesn’t need help to be removed from the muscles.  Plenty of studies show that massage has no effect on blood flow to the muscles.

Massage does help to relax muscles, though, which can help to relieve tight muscles. The same action can break up adhesions, a type of scar tissue that sometimes forms in muscle.  Massage promotes recovery.
