Metal Nanobumps For Better Artificial Body Parts

Roland Piquepaille writes "Everybody seems concerned these days by the risks associated with the use of nanotechnologies. So I'm pleased to report that Purdue engineers have proven that metal nano-bumps could improve artificial body parts, such as hips or knees. They based their theory on a simple fact. Surface bumps on conventional alloys used in prostheses are in the micron range, while they are ten times smaller in natural bones, around 100 nanometers. They thought a reduction of the size of these bumps in the prostheses would also reduce the risk of rejection by the body. They limited their experiments to petri dishes, but showed that adherence of new body cells to their new metal alloys was dramatically better than with existing alloys. Ssveral years will pass before improved artificial hips come to market. But the needs are growing. This overview contains more details and references."

    8 steps to greasing your anus for yoda doll insertion

    1) defecate. preferably after eating senna, ex lax, prunes, cabbage and hot sauces.
    2) wipe ass with witch hazel, soothes horrific burns
    3) prime anus with anal ease.
    4) slather richly a considerable amount of vaseline or other anal lubricants into your rectum at least until the bend and also take your yoda doll or yoda soap on a rope and liberally apply it.
    5) pucker your ballon knot several times actuating the sphincter muscle in order to work it in
    6) slowly rest yourself onto your yoda figurine
    7) make sure to have a mechanism by which to fish yoda out of your rectum, the soap on the rope is especially useful because that is built in.
    8) gyrate gleefully in your computer chair while your fat sexless geek nerd loser fat shit self enjoys the prostate massage you'll be getting. Read slashdot. Masturbate to anime. Email one of the editors hoping they will honor you with a reply. Join several more dating services - this time, you dont check the (desired - speaks english) and (desired - literate).

Argue that IDE is better than SCSI because you cant afford SCSI. Make claims about how Linux rules. Compile a kernel on your 486SX. Claim to hate windows but use it for Everquest. Admire Ghyslain's courage in making that wonderful star wars movie. Officially convert to the Jedi religion. Talk about how cool Mega Tokyo is. Try and make sure you do your regular 50 story submissions to Slashdot, all of which get rejected because people who arent fatter than CowboyNeal can't submit. Fondle shrimpy penis while making a yoda voice and saying, feel the force, padawan, feeel the foooorce, hurgm. Yes. Yes. When 900 years you reach, a dick half as big you will not have.

If you're concerned about nanotech, that doesn't mean you're universally freaked out by things merely because they are small. Just because both words start with "nano" doesn't mean they're always synonymous.

    It's like saying "Engineers are concerned by the risks of exposure to electric current, so I'm pleased to report that IBM has proven that electrons can be used to build a microscope."

I can't imaging being a halfway compassionate surgeon, having to tell an otherwise healthy and active 55-year-old that the best she can expect from her new knee is 10 years, tops, before they have to do the procedure all over again. This discovery has the potential to make repeat surgeries a thing of the past. However, the folks for whom this is absolutely fsking fantastic news are the people like me, and a couple of good acquaintances, who have congenital joint deformities.

    One gal has gone through her second complete hip replacement. Why? Because the first one rejected. She's not even 40. I was born mostly missing one hip socket. I got lucky; the socket finally grew deep enough to work, but I could still be staring down the edge of a scalpel in the future. And if I'm going to go through the 6 - 9 damn months that it usually takes to get mobile again, I'm going to want that new joint to outlast me, if at all possible.
