A man who lost part of his arm in a car crash has been trying it out, after doctors attached it to him using special wires. By the end of the experiment he could wiggle the robotic fingers, make a fist and grab objects with his new hand. It’s called the Life Hand. It has cost £2m and has taken the team five years to build.

Testing the new technology
After losing his forearm in a car crash, 26-year-old Pierpaolo Petruzziello agreed to participate in a one-month medical experiment to test out a robotic hand that can be controlled by a patient’s thoughts. Now, doctors say that the test run was successful, and may open the door for major developments to come.

More progress to come
Unlike most other prosthetics, this robot hand wasn’t implanted directly into Petruzziello, but was connected with a series of electrodes that were attached to the nerve endings on his severed arm.
The Associated Press reports that, at a press conference, the medical team played video footage of the patient controlling the hand’s actions with his mind as the device sat next to him. During the experiment, he learned to wiggle his fingers, make a fist, and grab objects. Said Petruzziello, “It felt almost the same as a real hand… you can’t imagine what they did to me.” Neurologist Paolo Maria Rossini jokingly added, “Some of the gestures cannot be disclosed because they were quite vulgar.” (Awesome.)

This experience is very helpful for patients who have suffered only partial loss of a hand or arm
Other similar thought-controlled prosthetic experiments have been successful in the past, but all of those only worked when a limb was completely severed. Scientists hope that this development may offer solutions for patients who have suffered only partial loss of a hand or arm. Although the project lasted only a month, it was still the longest that electrodes had remained connected to a patient’s nervous system.

Further challenges ahead
Doctors acknowledge that the next challenge is to develop a more durable device that can function for years on end. It’s clear, though, that the significance of this particular success shouldn’t be downplayed. There may still be barriers to overcome, but if prosthetic science progresses as rapidly as it has, it should only be a matter of time before someone smashes through them — with a robotic fist or otherwise.

Yawning is one of the best-kept secrets in neuroscience, it is a powerful neural-enhancing tool. Yawning, for example, has been used for many decades in voice therapy as an effective means for reducing performance anxiety and hypertension in the throat.

Recent evidence that yawning is good for you
Several recent brain-scan studies have shown that yawning evokes a unique neural activity in the areas of the brain that are directly involved in generating social awareness and creating feelings of empathy. One of those areas is the precuneus, a tiny structure hidden within the folds of the parietal lobe. According to researchers at the Institute of Neurology in London, the precuneus appears to play a central role in consciousness, self-reflection, and memory retrieval. The precuneus is also stimulated by yogic breathing, which helps explain why different forms of meditation contribute to an increased sense of self-awareness. It is also one of the areas hardest hit by age-related diseases and attention deficit problems, so it’s possible that deliberate yawning may actually strengthen this important part of the brain.

Hence, yawning should be integrated into exercise and stress reduction programs, cognitive and memory enhancement training, psychotherapy, and contemplative spiritual practice. And, because the precuneus has recently been associated with the mirror-neuron system in the brain (which allows us to resonate to the feelings and behaviors of others), yawning may even help us to enhance social awareness, compassion, and effective communication with others.

You should try it
Try it. Force yourself to yawn 10 times and you will experience this fabulous technique. Don’t feel stressed about it, there is an unexplained stigma in our society implying that it’s rude to yawn, and most of us were taught this when we were young.

Yawning usually occurs when you’re tired, and it may be the brain’s way of gently telling you that a little rejuvenating sleep is needed. On the other hand, exposure to light will also make you yawn, suggesting that it is part of the process of waking up.

But yawning doesn’t just relax you—it quickly brings you into a heightened state of cognitive awareness. Students yawn in class, not because the teacher is boring but because it helps easing the brain’s state of sleepiness, thus helping you stay focused on important concepts and ideas. It regulates consciousness and our sense of self, and helps us become more introspective and self-aware.
Of course, if you happen to find yourself trapped in a room with a dull, boring, monotonous teacher, yawning will help keep you awake.

Yawning mechanisms
Yawning is also very contagious, when your friends yawn you start doing it too. The reason for this is that it helps people synchronize their behavior with others.
In fact, it’s so contagious for humans that even reading about it will cause a person to yawn.

Yawning, as a mechanism for alertness, begins within the first 20 weeks after conception. It helps regulate the circadian rhythms of newborns, and this adds to the evidence that yawning is involved in the regulation of wakefulness and sleep.

So what is the underlying mechanism that makes yawning such an essential tool? Besides activating the precuneus, it regulates the temperature and metabolism of your brain. It takes a lot of neural energy to stay consciously alert, and as you work your way up the evolutionary ladder, brains become less energy efficient. Yawning probably evolved as a way to cool down the overly active mammalian brain, especially in the areas of the frontal lobe. Some have even argued that it is a primitive form of empathy. Most vertebrates yawn, but it is only contagious among humans, great apes, macaque monkeys, and chimpanzees.

A real neurological treat
Dogs yawn before attacking, Olympic athletes yawn before performing, and fish yawn before they change activities. Evidence even exists that yawning helps individuals on military assignment perform their tasks with greater accuracy and ease.

Indeed, yawning may be one of the most important mechanisms for regulating the survival-related behaviors in mammals. So if you want to maintain an optimally healthy brain, it is essential that you yawn.

A chemical story
Numerous neurochemicals are involved in the yawning experience, including dopamine, which activates oxytocin production in your hypothalamus and hippocampus, areas essential for memory recall, voluntary control, and temperature regulation. These neurotransmitters regulate pleasure, sensuality, and relationship bonding between individuals, so if you want to enhance your intimacy and stay together, then yawn together.
Other neurochemicals and molecules involved with yawning include acetylcholine, nitric oxide, glutamate, GABA, serotonin, ACTH, MSH, sexual hormones, and opium derivate peptides. In fact, it’s hard to find another activity that positively influences so many functions of the brain.

Conclusion
You should yawn as many times a day as possible: when you wake up, when you’re confronting a difficult problem at work, when you prepare to go to sleep, and whenever you feel anger, anxiety, or stress. Yawn before giving an important talk, yawn before you take a test, and yawn while you meditate or pray because it will intensify your spiritual experience.

You can consciously yawn, it takes a little practice and discipline but it will make you feel incredibly relaxed, and highly alert.

Not bad for something that takes less than a minute to do.

If you’re looking for a list of good carbs and bad carbs, you might need to change your ideas about dieting a little. While certain carbs that are worse for your body than others, there aren’t really good carbs and bad carbs, just good amounts and less healthy amounts.

Counting Carbs
It seems like more and more people are counting carbs, or at least paying more attention to the amount and type of carbs they eat. Popular diets such as the Atkins Diet have convinced people that there are good carbs and bad carbs, and the bad carbs need to be avoided and the good carbs limited.

While it’s a good idea to keep your intake of “bad” carbs in check, many health experts recommend that carbohydrates should make up at least 55 percent of a person’s total caloric intake, while others say that number should be as high as 65 percent.

This is fairly high so you don’t want to discount carbs. At the same time, it’s clear these people aren’t talking about the carbs you’ll find in candy, cookies and other highly processed foods, so that’s where the idea of a list of good carbs and bad carbs comes from.

A List of Good Carbs and Bad Carbs
If you had to make a list of carbs that you should eat more of versus carbs you should avoid, it basically breaks down into simple carbs being “bad” and complex carbs being “good.”

Complex and simple are terms that have to do with how the food is broken down into energy (sugar) in the body. Simple carbs are broken down quickly, giving your blood sugar a spike and sending you running back to the kitchen or snack machine within hours of your last fix.

Complex carbs are the ones that give your body the best fuel. They are usually found in foods high in fiber, which break down more slowly, giving you a more steady blood sugar level through the day and making you feel less hungry and irritable when mid-afternoon rolls around.

It’s a great idea to get more of these carbs into your daily diet.

Here is a list of good carbohydrates :
- Fruit
- Vegetables
- Whole grains and foods made from whole grains, such as bread and cereal
- Beans
- Nuts
- Legumes

Bad carbohydrates are :
- Refined grains like white bread and white rice
- Processed foods such as cake, cookies and chips
- Soft drinks
- Alcohol

Just because these foods have less desirable carbs does not mean you should kick them out of your life forever. A list of good carbs and bad carbs should not be seen as a strict rule. Yes, you should get most of your carbs each day from the “good” list, but you certainly don’t have to cut our alcohol or skip the birthday cake, as long as you don’t make it an every day or every meal thing.

Cutting carbs for Weight Loss
Cutting back on the bad carbs can help you lose weight, as well as give you a feeling of more energy and less irritability. Carbs are the fuel that makes your body run. Putting the right fuel in your engine makes a world of difference.

Because the good carb foods tend to have higher fiber and lower calories than many processed bad carb foods, you’ll find yourself feeling fuller while eating fewer calories though it’s possible you’ll be eating a bigger volume of food.

If you think about the kinds of foods you’re adding and the ones you’re giving up, then this makes sense.

It would take a lot more fruit to equal the same number of calories you’d eat in a candy bar, and you’ll probably feel satisfied after one piece or serving of fruit which is much lower in calories than the candy bar. Even better, you’ll feel satisfied for a long period of time and won’t feel the need for another unhealthy snack later in the day.

Postcode lottery
Thousands of people with cancer are dying prematurely because they live in the “wrong” part of the country, a government report revealed a few days ago.
Charities and MPs condemned the variations, which mean that sufferers in some parts of the country have significantly less chance of surviving at least a year after diagnosis of cancer.
Although overall cancer survival rates have improved, almost all NHS primary care trusts (PCTs) in England are failing to match the best cancer survival rates in Europe despite the introduction of a national Cancer Reform Strategy two years ago.

A real problem
Patients in Herefordshire are more than three times more likely to die within a year of diagnosis of lung cancer compared with patients in Kensington and Chelsea, according to the progress report published by the Department of Health.
Cancer Research UK called for urgent action from the Government, adding that there was “no excuse” for the differences in life expectancy between different areas.
The second annual progress report on the Cancer Reform Strategy comes after Mike Richards, the National Cancer Director, estimated that late diagnosis of cancer causes at least 10,000 premature deaths a year.
In an article for the British Journal of Cancer, Professor Richards writes: “These delays in the patient presenting with symptoms and cancer being diagnosed at a late stage inevitably costs lives.
“The situation is unacceptable so the first big step has been to understand why the delays occur.”

Patients not being treated / diagnosed early enough
Every year more than 290,000 people in Britain have some form of cancer diagnosed, and about 150,000 people die.
But while eight out of ten patients with bowel cancer live for more than a year after diagnosis in Telford and Wrekin in the West Midlands, less than six out of ten (57.9 per cent) do so in Waltham Forest, North London.
Ninety-nine per cent of all patients in Torbay, Devon, survive at least a year after a diagnosis of breast cancer, but this figure is 89 per cent in Tower Hamlets.
Harpal Kumar, chief executive of Cancer Research, said: “These shocking statistics confirm that the cancer postcode lottery remains a real problem.
“Patients are undoubtedly not being diagnosed early enough in large parts of the country, nor are they getting equal access to the best treatments, such as surgery for lung cancer.
“It’s a disgrace that such a small proportion of primary care trusts have survival rates that match the best figures in Europe, or even the best rates in Europe ten years ago.
“This needs urgent action.”

A lack of proper diagnostic tests and understanding of symptoms
A separate report by MPs on the All Party Parliamentary Group for Cancer, also published today, suggests that older patients may also be at risk of dying earlier due to a lack of proper diagnostic tests or symptoms.
Mark Simmonds, MP, a Conservative health spokesman, said: “We are concerned by this data, which demonstrates the unacceptable inequalities in treatment and care for cancer patients. In 2000 the Government pledged that reducing health inequalities was a key aim, yet nearly a decade on the gap has widened and five-year cancer survival rates still lag behind those of comparable European countries.”

Andy Burnham’s pledge
Andy Burnham, the Health Secretary, responded: “Cancer treatment in Britain has improved vastly in recent years and this is shown in the falling mortality rates and increasing survival rates.
“However, we know that survival rates vary across the country, particularly in deprived areas, so this year’s report has deliberately focused on local variations so we can highlight to the NHS where they need to take action.
“I hope that the publication of this data combined with the Prime Minister’s pledge to give patients key diagnostic tests within just one week of seeing their GP will save thousands more lives.”
