Want a new head? You can get one soon.... If you're a monkey

head-transplant-monkeyA head transplant seems like something you’d see in a science fiction film. Almost a hundred years ago a scientist succeeded in grafting one dog’s head onto another dog’s neck. The dogs did not live very long but until a little while ago it was the closest we had come to a head transplant. We have successfully done head transplants on mice but never on a more human-like creature. That, of course, is where the challenge comes in.
Researchers located at the Harbin Medical University in China are confident that they can do better than a simple mouse head transplant and can do a head transplant on a monkey. Of course, simply putting one animal’s head on another animal is no feat. The body of the original animal and the transplanted head would have to be connected via the spinal cord and the animal will have to be able to survive for at least a short period of time. Only some of the nerves will be reconnected by they are theorized to be enough to have automatic functions, such as breathing.
As you may have thought, an experiment like this one is full of ethical questions and concerns. Many people understand that animals must be tested on to keep people safe but in this particular situation in which the animal is unlikely to live very long brings up even more concerns. Is this for the betterment of the human race or is it simply abusing animals?
If this all works out according to plan, this may be a big step in human history. When someone is so sick thathead-transplant-dog they are experiencing multi organ failure a head transplant may be a potential way in the future that a person like that could continue to live. In fact, Sergio Canavero is a neurosurgeon who has vowed to attempt a human head transplant within two years. Dr. Canavero has already located a volunteer for the first every headtransplant: Valery Spiridonov. Mr. Spiridonov is a terminally ill man from Russia and says he wants to help make a scientific breakthrough. According to Dr. Canavero’s math the head transplant would cost about $15 million and is likely to take place in China or the United States.

One of the primary issues with a head transplant is that scientists have not yet discovered a way to fully repair a severed spinal cord. Even if the spinal cord from the head to attached to the body the body does not repair a severed spinal cord. This is why people who are paraplegics never get better. All we can hope is that these researchers have found a way to repair a severed spinal cord. If this was accomplished not only would the monkey head transplant be a huge success and the human head transplant be a success but people with spinal cord injuries would be able to walk again.


If the researchers in China have discovered ground breaking procedures to repair a severed spinal cord it could very much change the world and the health of lots of people. Accidents that result in a severed spinal cord wouldn’t end in paralysis for people or animals.

Most Dangerous Jobs In The World

If you are looking for a more adventurous job and you are considering one from the list below, you should think twice. They might sound romantic, exciting, and well paid, but "dangerous" describes them best. We made a list of the most dangerous jobs in the world. Which one do you think sounds the most frightening? 10. Snake Milker flickr.com Source:  Snake milkers spend their days pushing snakes (certain types only) into a plastic container to extract or milk the snake. Snake venom (poison) can be used for many things, but the most important is its use in medical research or to produce "antivenom." Even though safety measures are applied, each milking process is highly dangerous. The rate of milkers who haven’t been bitten on the job is surprisingly low. Average annual salary:  $30,000 9.

Flat Earther Goes One on One With An Astronaut

Of all the conspiracy theories that have surfaced in our history, the Flat Earth Theory is certainly one of the more controversial and heavily discussed. Having had countless of individuals step up to try and disprove astronauts and scientists alike, it never fails to amuse and surprise us when it occurs. One of the more alarming approaches is when a Flat Earther argues with an astronaut on TV, and it’s hard to watch. Daily Mirror Mark Sargent of Seattle has been a conspiracy theorist who’s had quite the following with Flat Earthers. This theory has been getting a lot of traction as of late with people trying to disprove what we as humans have proved and believed for centuries. There is no real evidence to suggest the Earth is flat, with a multitude of concluding evidence that has proved that, in fact, the Earth is round. To argue against scientists is a bold action in itself, and to take it a step further to argue with astronauts who have...

The Most Groundbreaking Cancer Research of 2017

We've come a long way in the diagnosis, treatment, and prevention of cancer. The exciting discoveries of the past year mean more lives will be saved from cancer than ever before. Advances in immunotherapy PLENTY M/SHUTTERSTOCK Among the  completely reassuring things scientists wish you knew about cancer  is the research that's being done to eradicate the disease, in which abnormal cells multiply and take over in the body. Last year there were  over 1,685,000 cases  of cancer diagnosed, and nearly 600,000 people died. Standard therapies so far are surgery, radiation to kill the cells, and chemotherapy, which alters the DNA of cancer cells to stop them from reproducing. But radiation and chemo damage healthy cells too, so researchers have been looking for better treatments. New immunotherapy drugs use the patient's own immune cells to attack cancer. Stephen Hunger, MD, chief of the Division of Oncology, chief of the Division of Pediatric Oncology, and director...
