The underlying mechanisms responsible for phantom limb pain remain unclear. However, it appears that it may arise as a consequence of abnormal neural circuitry in central areas of the brain.
Limited success has been achieved with mirror therapy in which reflections of the unaffected limb can be used to create the illusion that the amputated limb is moving.
Sensors that could detect muscular activity were attached to the stump of the missing arm. The signals received by these sensors were then used to produce an image of an active arm on a computer screen.
Patients were trained to use these signals to control the virtual arm, drive a virtual race car around a track and to copy the movements of an arm on screen with their phantom movements. After twelve 2-hour treatment sessions, the patients underwent follow-up interviews 1, 3 and 6 months later.
Based on the patients' ratings, the intensity, quality, and frequency of pain had reduced by 50% after the treatment.
At the start of the study, 12 patients reported feeling constant pain whereas only 6 did 6months after the treatment. However, one patient thought that there was not a considerable difference in the levels of phantom pain before and after treatment.

Natural tooth repair method, using Alzheimer's drug, could revolutionise dental treatments
A new method of stimulating the renewal of living stem cells in tooth pulp using an Alzheimer’s drug has been discovered by a team of researchers at King’s College London.
Following trauma or an infection, the inner, soft pulp of a tooth can become exposed and infected. In order to protect the tooth from infection, a thin band of dentine is naturally produced and this seals the tooth pulp, but it is insufficient to effectively repair large cavities. Currently dentists use manmade cements or fillings, such as calcium and silicon-based products, to treat these larger cavities and fill holes in teeth. This cement remains in the tooth and fails to disintegrate, meaning that the normal mineral level of the tooth is never completely restored.
However, in a paper published today in Scientific Reports, scientists from the Dental Institute at King’s College London have proven a way to stimulate the stem cells contained in the pulp of the tooth and generate new dentine in large cavities, potentially reducing the need for fillings or cements.
The novel biological approach could see teeth use their natural ability to repair large cavities rather than using cements or fillings.
Significantly, one of the small molecules used by the team to stimulate the renewal of the stem cells included Tideglusib, which has previously been used in clinical trials to treat neurological disorders including Alzheimer’s disease.
Using biodegradable collagen sponges to deliver the treatment, the team applied low doses of small molecule glycogen synthase kinase (GSK-3) inhibitors to the tooth. They found that the sponge degraded over time and that new dentine replaced it, leading to complete, natural repair. Collagen sponges are commercially-available and clinicallyapproved, again adding to the potential of the treatment’s swift pick-up and use in dental clinics.

Outcry as Chinese school makes iPads compulsory
Apple products are incredibly popular in China, but not everyone can afford them
A school in northern China has been criticised for enforcing iPad learning as part of its new curriculum, it's reported.
According to China Economic Daily, the Danfeng High School in Shaanxi province recently issued a notice saying that, “as part of a teaching requirement, students are required to bring their own iPad” when they start the new school year in September.
Staff told the paper that using an iPad would “improve classroom efficiency”, and that the school would managean internet firewall, so that parents would not have to worry about students using the device for other means.
However, China Economic Daily says that after criticism from parents, who felt that it would be an “unnecessary financial burden”, eadmaster Yao Hushan said that having an iPad was no longer a mandatory requirement. Mr Yao added that children who don't have a device could still enrol, but that he recommended students bring an iPad as part of a “process of promoting the digital classroom”.
The incident led to lively discussion on the Sina Weibo social media platform. “Those parents that can't afford one will have to sell a kidney!” one user quipped.
Others expressed concerns about the health implications of long-term electronic device use. “I worry about their vision,” one user said, and another said they would all become “short-sighted and have to wear glasses.”
But others felt that it was a good move in line with new modern ways of teaching. “They are affordable for the average family, one said, “they don't necessarily need to buy the latest model.”

The word STAFF in “Staff told the paper that using an iPAD would improve classroom efficiency” refers in this context to:
When is it time to stop studying?
It's 10 p.m. and six government employees are out checking the streets of Seoul, South Korea. But these are not police officers searching for teenagers who are behaving badly. Their mission is to find children who are still studying. And stop them. Education in South Korea is very competitive. The aim of almost every schoolchild is to get into one of the country’s top universities. Only the students with the best grades get a place. The school day starts at 8 a.m. and the students finish studying somewhere between 10 p.m. and 1 a.m. at night. This is because many go to private academies called hagwon after school. Around 74 percent of all students attend a hagwon after their regular classes finish. A year’s course costs, on average, $2,600 per student. In Seoul, there are more private tutors than schoolteachers, and the most popular ones make millions of dollars a year from online and in-person classes. Most parents rely on private tutoring to get their children into a university. With so much time spent in the classroom, all that students in South Korean high schools do is study and sleep. Some of them are so exhausted that they cannot stay awake the next day at school. It is a common sight to see a teacher explaining the lesson while a third of the students are asleep on their desks. The teachers don’t seem to mind. There are even special pillows for sale that fit over the arms of the chairs to make sleeping in class more comfortable. Ironically, the students spend class time sleeping so that they can stay up late studying that night. The South Korean government has been aware of the faults in the system for some time, but now they have passed some reforms. Today, schoolteachers have to meet certain standards or take additional training courses. However, the biggest challenge for the government is the hagwons. Hagwons have been banned from having classes after 10 p.m., which is why there are street patrols searching for children who are studying after that time. If they find any in class, the owner of the hagwon is punished and the students are sent home. It's a strange world, where some children have to be told to stop studying while others are reluctant to start.

Not Long Ago people believed that in the future we would work less, have more free time, and be more relaxed. But sadly this has not happened. Today we work harder, work longer hours, and are more stressed than ten years ago. We walk faster, talk faster, and sleep less than previous generations. And although we are obsessed with machines which save us time, we have less free time than our parents and grandparents had. But what is this doing to our health? An American journalist James Gleick in a new book, Faster: the Acceleration of just about everything, says that people who live in cities are suffering from 'hurry sickness'- we are always trying to do more things in less time. As a result, our lives are more stressful. He says that if we don't slow down, we won't live as long as our parents. For most people, faster doesn't mean better.
No time for the news
Newspaper articles today are shorter and the headlines are bigger. Most people don't have enough time to read the articles, they only read the headlines! On TV and the radio, newsreaders speak more quickly than ten years ago.
No time for stories
In the USA there is a book called One-Minute Bedtime Stories for children. These are shorter versions of traditional stories, specially written for 'busy parents' who want to save time!
No time to listen
Some answerphones now have 'quick playback' buttons so that we can re-play people's messages faster - we can't waste time listening to people speaking at normal speed!
No time to relax
Even when we relax we do everything more quickly. Ten years ago when people went to art galleries they spent ten seconds looking at each picture. Today they spend just three seconds!
No time for slow sports
In the USA the national sport, baseball, is not as popular as before because it is a slow game and matches take a long time. Nowadays many people prefer faster and more dynamic sports like basketball.
…but more time in our cars
The only thing that is slower than before is the way we drive. Our cars are faster but the traffic is worse so we drive more slowly. We spend more time sitting in our cars, feeling stressed because we are worried that we won't arrive on time. Experts predict that in ten years' time the average speed on the road in cities will be 17 km/h.
