Homing pigeons are the original sat-navs!

Tuesday, August 11th, 2009

SNN0517A_124638aIt has been an aged-old mystery why pigeons always find their way home. Even if at times they head off to the wrong directions at the start of the flight, they still manage to return to where they took off, puzzling cultures and scientists all over the world for a very long time.
Researchers at the University of Auckland recently announced that the mystery has now been solved, saying homing pigeons follows magnetic fields around the earth for routes of their flight, and doing the same to find their way home.
Pushing further that the homing pigeons are probably the first satellite navigators, the Auckland scientists said the pigeons have a unique global positioning technology built into their system. The results of the research further state that such ability of the homing pigeons is like an orientation of map-and-compass where a pigeon first figure out its surrounding then fly off and find guide to take themselves home.
Furthermore, it has been published that homing pigeons’ beaks have magnetic particles that act like a compass, providing the birds with an accurate sense of direction. Not only that, the beak reacts to the earth’s external magnetic fields with such high sensitivity and specific manner so they always get the locations right.
Another mystery the researchers have answers for is the question of pigeons flying off in the wrong directions. It showed that the birds are doing this not as a random act but as a helpful method of knowing the magnetic fields and its contour lines,
The researchers also surmise that such proven theory is not limited to homing pigeons alone, but most likely with other birds and some animals which are influenced by the magnetic fields of our planet.

Joint Replacements method now uses SatNav Science

D91A86382A5AE6266533BC566BEF366B.0Satnavs aren’t limited alone to guiding motorists through roads and streets. The Orthopilot is a testament that makers of the devices are pursuing satnavs practicability in medicine and human health concerns, particularly to surgeons who perform knee replacements. In UK alone, close to 60,000 people need knee replacement each year.

The Orthopilot is a technological gadget now employed by doctors performing joint surgeries such as knees and hips replacement that employs GPS technology. Developed in the United Kingdom, the Orthopilot helps surgeons align artificial knee joints, making the traditional method close to being a thing of the past.

While regular knee operations are more of guess-work and requires extensive experience, the new technology guides the surgeons in crucial operations in surgery such as joints alignment. When a joint replacement is out of line even by the smallest millimeter, the surgery is bound to be a failure in the future years. This is because the miscalculation on the alignment will put a load on the artificial knee and the bone itself, subjecting the area and bones involved to heavy stress and wear.

Also, the low 80% success rate of regular knee replacement procedure is quite an alarming number, and the repeat operations are also high, which is even ringing more alarm bells.

But what used to be done with the naked eye, the surgeons can now do so more effectively with the Orthopilot. With over 95% reported success rates, surgeons are saved the taxing effort of perfecting every single operation the old way. With the help of computer guides, surgeons can now perform transplants and operations on joints with remarkable accuracy.

The Orthopilot works by providing from its software the maps of alignment and anatomy of the knee and other joints. The information is sent to the surgeon so that in performing the implant, exact orientations required are met. Hence, repeat operations are cut drastically and health risks are avoided.
