Cloned Horses Coming to the Olympics? - 0 views

  • July 2012 the Féderation Equestre Internationale (FEI) lifted a ban on cloned horses and their progeny competing in the Olympic Games

  • cloning process can cost more than a hundred thousand U.S. dollars.

  • Today, there are only a few hundred equine clones, created mainly for breeding
  • a top stallion for in vitro fertilization can go for tens of thousands of dollars
  • most male horses in high-level competitions are geldings
  • a mare can bear only so many foals
  • most common use for cloned horses is to perpetuate genetic material. The original horse can travel and compete, while its copy becomes a full-time foal-making machine
  • 2007 the FEI's general assembly decided that cloning was "potentially against the spirit of sport in that it was unfair
  • key factor in the decision was the high price of cloning, which has since come
  • federation determined that the clones were only 98 percent copies of the originals
  • the error margin of a full 2 percent was what ultimately caused the FEI to overturn the ban
  • widely agreed that environment, training, nutrition, and relationship with the rider have an incalculable impact on the horse's performance
  • American Quarter Horse Association won't allow clones
  • Neither will the Jockey Club, which registers thoroughbreds in North America
  • FEI has been careful to emphasize that cloning is a breeding technique only
  • only 300-odd horses competing in the Olympics, clones have to battle their way to the top just as traditionally bred horses do.

NASA - Curiosity Spotted on Parachute by Orbiter - 0 views

  • The image scale is 13.2 inches (33.6 centimeters) per pixel
  • The parachute appears fully inflated and performing perfectly. Details in the parachute, such as the band gap at the edges and the central hole, are clearly seen. The cords connecting the parachute to the back shell cannot be seen, although they were seen in the image of NASA's Phoenix lander descending, perhaps due to the difference in lighting angles. The bright spot on the back shell containing Curiosity might be a specular reflection off of a shiny area. Curiosity was released from the back shell sometime after this image was acquired.

  • used a Dimension SST 1200es 3D printer and Stratasys production system. so as to create a prosthetic light enough for young Emma to continue moving around freely.
  • makes use of medical-grade materials that contributed to the success of the device. The ABS plastic material for the magic-arms device was described as “human friendly, strong, and durable.”
  • using a robust 3-D printing technology means that doctors can rely on a system to accommodate wide-ranging specifications for patients
  • allow the doctors to keep adjusting her prosthetic; it will evolve
  • Creating a lightweight exoskeleton by hand would be extremely difficult, and 3-D printing technology enabled the researchers to customize WREX to exact specifications
