– The leader of the group asked militants to allow the president do his job
The Ijaw Youth Council has sent a message to militants in the Niger Delta region to allow President Muhammadu Buhari implement the project he has for the region.
Mr. Udengs Eradiri who is the president of the group spoke in Yenagoa, the capital of Bayelsa on Wednesday, October 26 where he said that although Buhari’s body language seemed hostile at first, it was evident that he has changed and should therefore be given a chance to perform.
Eradiri applauded the plan to increase fund for amnesty and said such development be extended to other Niger Delta projects.
“Yes, the militants should give the government a chance. But the government needs to be proactive and not falling into this stereotype attitude.
“The President may be doing the right thing but when there is delay, his body language may be misinterpreted. For instance, if this current step of the President had come earlier, l don’t see any sane agitator going against him.
“The President has taken an action. But did we have to lose all these lives, economy and all the constraints and emotional crisis before such a letter should be transmitted? Sometimes, when you do something late, it has repercussions. If the actions Mr. President is taking now had been taken earlier, we wouldn’t have got to this point where the economy will be lying prostrate. We need more proactive steps from the President.”
Eradiri also urged the president to ensure discipline in the utilisation of the allocated funds and prudent management by people who understood the problems in the region.
He said: “We want to also state that while approving funds for institutions like this, the anti-corruption drive must be activated to ensure that the institutions live up to their expectations to ensure that funds are not diverted.
“Those in the position to manage the amnesty office and other institutions addressing the issues of the region must be people who have knowledge of the issues. If he doesn’t have the right people to address the issues, even the funding will be misplaced.”

Next-generation smartphone battery inspired by the gut

FULL STORY

Computer visualisation of villi-like battery material.

A new prototype of a lithium-sulphur battery -- which could have five times the energy density of a typical lithium-ion battery -- overcomes one of the key hurdles preventing their commercial development by mimicking the structure of the cells which allow us to absorb nutrients.
Researchers have developed a prototype of a next-generation lithium-sulphur battery which takes its inspiration in part from the cells lining the human intestine. The batteries, if commercially developed, would have five times the energy density of the lithium-ion batteries used in smartphones and other electronics.
The new design, by researchers from the University of Cambridge, overcomes one of the key technical problems hindering the commercial development of lithium-sulphur batteries, by preventing the degradation of the battery caused by the loss of material within it. The results are reported in the journal Advanced Functional Materials.
Working with collaborators at the Beijing Institute of Technology, the Cambridge researchers based in Dr Vasant Kumar's team in the Department of Materials Science and Metallurgy developed and tested a lightweight nanostructured material which resembles villi, the finger-like protrusions which line the small intestine. In the human body, villi are used to absorb the products of digestion and increase the surface area over which this process can take place.
In the new lithium-sulphur battery, a layer of material with a villi-like structure, made from tiny zinc oxide wires, is placed on the surface of one of the battery's electrodes. This can trap fragments of the active material when they break off, keeping them electrochemically accessible and allowing the material to be reused.
"It's a tiny thing, this layer, but it's important," said study co-author Dr Paul Coxon from Cambridge's Department of Materials Science and Metallurgy. "This gets us a long way through the bottleneck which is preventing the development of better batteries."
A typical lithium-ion battery is made of three separate components: an anode (negative electrode), a cathode (positive electrode) and an electrolyte in the middle. The most common materials for the anode and cathode are graphite and lithium cobalt oxide respectively, which both have layered structures. Positively-charged lithium ions move back and forth from the cathode, through the electrolyte and into the anode.
The crystal structure of the electrode materials determines how much energy can be squeezed into the battery. For example, due to the atomic structure of carbon, each carbon atom can take on six lithium ions, limiting the maximum capacity of the battery.
Sulphur and lithium react differently, via a multi-electron transfer mechanism meaning that elemental sulphur can offer a much higher theoretical capacity, resulting in a lithium-sulphur battery with much higher energy density. However, when the battery discharges, the lithium and sulphur interact and the ring-like sulphur molecules transform into chain-like structures, known as a poly-sulphides. As the battery undergoes several charge-discharge cycles, bits of the poly-sulphide can go into the electrolyte, so that over time the battery gradually loses active material.
The Cambridge researchers have created a functional layer which lies on top of the cathode and fixes the active material to a conductive framework so the active material can be reused. The layer is made up of tiny, one-dimensional zinc oxide nanowires grown on a scaffold. The concept was trialled using commercially-available nickel foam for support. After successful results, the foam was replaced by a lightweight carbon fibre mat to reduce the battery's overall weight.
"Changing from stiff nickel foam to flexible carbon fibre mat makes the layer mimic the way small intestine works even further," said study co-author Dr Yingjun Liu.
This functional layer, like the intestinal villi it resembles, has a very high surface area. The material has a very strong chemical bond with the poly-sulphides, allowing the active material to be used for longer, greatly increasing the lifespan of the battery.
"This is the first time a chemically functional layer with a well-organised nano-architecture has been proposed to trap and reuse the dissolved active materials during battery charging and discharging," said the study's lead author Teng Zhao, a PhD student from the Department of Materials Science & Metallurgy. "By taking our inspiration from the natural world, we were able to come up with a solution that we hope will accelerate the development of next-generation batteries."
For the time being, the device is a proof of principle, so commercially-available lithium-sulphur batteries are still some years away. Additionally, while the number of times the battery can be charged and discharged has been improved, it is still not able to go through as many charge cycles as a lithium-ion battery. However, since a lithium-sulphur battery does not need to be charged as often as a lithium-ion battery, it may be the case that the increase in energy density cancels out the lower total number of charge-discharge cycles.
"This is a way of getting around one of those awkward little problems that affects all of us," said Coxon. "We're all tied in to our electronic devices -- ultimately, we're just trying to make those devices work better, hopefully making our lives a little bit nicer."

natural ways of treating any form of pain


A new federal report revealed that the majority of U.S.1
adults (more than 54 percent) had some type of musculoskeletal pain disorder such as back, joint or neck pain in 2012 (the latest year for which statistics are available).
Its prevalence is indicative of the significant price Americans pay for pain — it's a leading cause of disability and major contributor to health care expenses and disability compensation.
Also revealing, people suffering from pain were significantly more likely to have used a complementary health approach compared to people without pain — nearly 42 percent versus 24 percent, respectively.
The reason wasn't addressed by the study, but time and again, conventional medicine fails to relieve many people's pain.
Congressional testimony from the American Society of Interventional Pain Physicians (ASIPP) stated that Americans consume 80 percent of the pain pills in the world,2and in a survey of more than 2,000 pain patients in the U.S., most said they were taking a dangerously addictive opioid pain medication.3
Research suggests, however, that these drugs work for only about three months, after which changes in your brain may lead to increased feelings of pain along with added emotional upset, including feelings of hopelessness and desperation.4
Many pain sufferers have tried virtually every treatment that conventional medicine has to offer — medications, injections, surgery and more — only to find that their pain hasn't gotten better and they may be struggling with treatment-induced side effects as well (one of the worst of which is opioid addiction).
At that point (and for many far sooner), it's only natural that you would begin to seek other options, which brings many people to holistic, complementary or "alternative" health care options for relief.

Science-Backed Natural Pain Relief Options

A recent study published in Mayo Clinic Proceedings evaluated several complementary approaches for pain relief.5 The options that follow have been scientifically proven to help with relief, according to the report.
Acupuncture
One of the most common uses for acupuncture is in treating chronic pain. One analysis of the most robust studies available concluded that acupuncture has a clear effect in reducing chronic pain, more so than standard pain treatment.6
Study participants receiving acupuncture reported an average 50 percent reduction in pain, compared to a 28 percent pain reduction for standard pain treatment without acupuncture. It's likely that acupuncture works via a variety of mechanisms.
In 2010, for instance, it was found that acupuncture activates pain-suppressing receptors and increases the concentration of the neurotransmitter adenosine in local tissues7 (adenosine slows down your brain's activity and induces sleepiness).
Massage Therapy
A systematic review and meta-analysis, published in the journal Pain Medicine, included 60 high-quality and seven low-quality studies that looked into the use of massage for various types of pain, including muscle and bone pain, headaches, deep internal pain, fibromyalgia pain and spinal cord pain.8
The review revealed that massage therapy relieves pain better than getting no treatment at all.
Relaxation Techniques
Breathing exercises, guided imagery, meditation and other relaxation techniques may provide relief, especially from pain from tension headaches and migraines.
Research by an associate professor at Harvard Medical School, Dr. Herbert Benson, found that people who practice relaxation methods such as yoga and meditation long-term have more disease-fighting genes switched "on" and active, including genes that protect against pain and rheumatoid arthritis.9
Exercise
Among people who had experienced back pain, those who exercised had a 25 percent to 40 percent lower risk of having another episode within a year than those who did no exercise.10
Strength exercises, aerobics, flexibility training and stretching were all beneficial in lowering the risk of back pain.
Motor control exercises (MCE), which help to improve coordination of muscles that support your spine,11 may also help. One systematic review found MCE led to reductions in pain and disability and improvements in perceived quality of life compared with minimal intervention.12
Yoga, which is particularly useful for promoting flexibility and core muscles, has also been proven to be beneficial if you suffer from back pain.
People suffering from low back pain who took one yoga class a week had greater improvements in function than those receiving medicine or physical therapy.13 The Yoga Journal has an online page demonstrating specific poses that may be helpful.14
Medical Marijuana
There are cannabinoid receptors in your brain, lungs, liver, kidneys, immune system and more. Both the therapeutic and psychoactive properties of marijuana occur when a cannabinoid activates a cannabinoid receptor.
Research is still ongoing on just how extensive their impact is on our health, but to date it's known that cannabinoid receptors play an important role in many body processes, including metabolic regulation, cravings, pain, anxiety, bone growth and immune function.15
Some of the strongest research to date is focused on marijuana for pain relief. In one study, just three puffs of marijuana a day for five days helped those with chronic nerve pain to relieve pain and sleep better.16
Also revealing, in states where medical marijuana is legal, overdose deaths from opioids like morphine, oxycodone and heroin decreased by an average of 20 percent after one year, 25 percent after two years and 33 percent by years five and six.17

Turmeric for Pain Relief

Turmeric was once most known for being a flavorful and colorful addition to curry, but in the scientific world, turmeric has earned a reputation for being a multi-faceted healer. Turmeric contains curcumin, which has notable anti-inflammatory properties.
It can inhibit both the activity and the synthesis of cyclooxygenase-2 (COX2) and 5-lipooxygenase (5-LOX), as well as other enzymes that have been implicated in inflammation.
A 2006 study found that a turmeric extract composed of curcuminoids (curcumin is the most investigated curcuminoid) blocked inflammatory pathways, effectively preventing the launch of a protein that triggers swelling and pain.18
Turmeric has been found to significantly improve post-operative pain and fatigue,19and in a study of osteoarthritis patients, those who added only 200 milligrams (mg) of curcumin a day to their treatment plan had reduced pain and increased mobility.
Time magazine even published the story of one doctor who marveled at one of his older hip patient's lack of pain and remarkably swift recovery from surgery. The patient took turmeric regularly, and the results so impressed the physician that he began taking the supplement himself.20

Essential Oils for Pain Relief

Essential oils are concentrated, aromatic plant extracts that have been used for thousands of years for emotional, cosmetic, medical and even spiritual purposes. One of their most popular uses is also for relief of chronic and acute pain.
There are a number of ways to use essential oils, including via aromatherapy. Lavender aromatherapy, for instance, has been shown to lessen pain following needle insertion21 while green apple scent significantly relieves migraine pain. Other essential oils noted for pain relief, including relief from joint pain, include:22
Lavender
Marjoram
Chamomile
Spruce
Sandalwood
Wintergreen
Clove
Fennel
Ginger
Indian frankincense or boswellin has even been found to significantly reduce inflammation in animal studies. It is actually one of my personal favorites, as I have seen it work well as a natural painkiller for many of my former rheumatoid arthritis (RA) patients. Other essential oils that may be particularly beneficial for relieving RA pain and inflammation include:23
  • Peppermint
  • Orange
  • Ginger
  • Myrrh
  • Turmeric
For relief of chronic muscular pain or joint aches, try mixing 15 to 60 drops of your chosen essential oil with 1 ounce of carrier oil, then massaging it into the painful area.
You can also mix three drops of thyme oil with 2 teaspoons of sesame oil to use as massage oil and apply on your abdominal area to relieve pain. This may also be used as a massage oil to treat other types of pain, including insect and animal bites and stings. You can also use essential oils in the bathtub to relieve pain. Add two to 12 drops (depending on essential oil) into a teaspoon of honey, whole milk, vegetable oil or other dispersing agent then add to the bath once you are in the tub.

Homeopathy Also Found to Be Effective for Low Back Pain

Homeopathic solutions contain miniscule doses of plants, minerals, animal products or other compounds that cause symptoms similar to what you are already experiencing. The remedies have been diluted many times over, and the idea is that the substance will stimulate your body's own healing powers.
One study of 129 people with chronic low back pain found traditional homeopathic treatment was effective for treating low back pain, leading to improvements in health-related quality of life and decreases in the use of conventional treatment and health care services.
The number of patients using drugs to treat their back pain was cut in half after homeopathic treatments.24 It's best to work with an experienced homeopath to guide you in treatment for pain relief, however some common homeopathic remedies for back pain include:25
Aesculus, for dull pain with muscle weakness
Arnica Montana, for pain as a result of trauma
Gnaphalium, for sciatica that alternates with numbness
Lycopodium, for burning pain, especially with gas or bloating
Colocynthis, for weakness and cramping in the small of the back
Rhus toxicodendron, for stiffness and pain in the small of the back

Finding the Right Balance Between Relief and Healing

If you're in severe pain or struggling with chronic pain, it can quickly sideline your life. You'll need relief fast in order to function, which is why I recommend seeking the help of a pain specialist who is familiar with alternative treatments.
A knowledgeable practitioner can help you to both relieve pain in the short term while also facilitating healing by identifying the underlying causes of your pain. It's important to understand that medications are not the only option for pain relief, nor are they frequently the best such option.
When used cautiously and correctly, prescription pain relievers do have their place in medicine, but they became dangerous when used long term. For many people, lasting relief comes not from one modality but several, and it often includes making dietary changes as well.
It may take a process of trial and error for you to find what combination works for you — but please stay hopeful. You can break free from chronic pain and, ultimately, many people find they don't need drugs to do it.
