New hope for improved recovery after stroke

Researchers with Neuroscience Research Australia and their colleagues have identified a remarkable new of improving recovery after stroke. The team found that some stroke patients have a distorted or “scrambled” representation map of their hand. When a patient is touched in one location on the hand, they perceive the sensation as originating from another site. A recent study revealed that it is possible to correct this scrambled map, leading to improved motor functioning.

New hope for improved recovery after stroke

“This new evidence means that we can now focus on creating new rehabilitation strategies that can help to regain normal sensation and fine motor skill after a stroke,” says Dr Ingvars Birznieks. “As there is little awareness of this condition, we think that this dysfunction may be more common than previously thought. It is generally not detected during routine neurological examination and patients themselves are not aware of it. ”

This sensory mismatch results in difficulties to perform skilled movements requiring fine control, such as using a knife and fork or a pen. Current rehabilitation strategies to regain and arm function after stroke largely focus on regaining movement, however, the ability to simply move a limb is not enough as proper use of our hands relies on sensory information about the objects we touch. “Would you be able to pick a raspberry or hold an egg with numb fingertips?” asks Dr Birznieks.

These new findings may explain why some cannot regain the dexterity of hand movements for years following a .

“Increasing awareness and understanding of this dysfunction will help to identify the affected patients,” says Dr Birznieks, “and by developing relevant rehabilitation strategies designed specifically to normalise tactile representation maps we hope to improve their chances to regain fine sensation and control over the affected hand.”

Surgeons perform double hand transplant on a child for the first time – ScienceAlert

Surgeons in the US have successfully transplanted two donor hands onto an eight-year-old boy called Zion Harvey after he’d had them amputated due to a serious infection. This is the first time the procedure has ever been performed on a child, just four years after it was pioneered by the same surgical team on an adult patient.

“I made the decision from a medical standpoint, but ultimately, to have the surgery was Zion’s decision,” Zion’s mother Pattie Ray said in an interview with TIME. “He wanted to do what other children can do without so much trouble.”

Several years ago, Zion contracted a severe infection of unknown origins, and it necessitated the amputation of both hands and feet, and more recently a kidney transplant. The silver lining when it came to the kidney transplant is that the anti-rejection medication he had to take for it made him a strong candidate for a double hand transplant.

Just three months after he’d been put on the wait-list, a donor came through. The procedure was performed earlier this month by a team at the Children’s Hospital of Philadelphia (CHOP) and surgeons from Penn Medicine.

“Each year, there are only 15 children, based on the databases, that would even be eligible to donate hands,” lead surgeon L. Scott Levin, Chairman of the Department of Orthopaedic Surgery at Penn Medicine and Director of the Hand Transplantation Program at CHOP, says in the video below. “And then it comes down to the organ procurement organisations approaching families at a terrible time – the loss of a child. So the fact that he was put on the waiting list for hands in April, and three months later, this came along – that in and of itself is a remarkable story.”

The 10-hour surgical procedure was performed by a 40-member team of physicians, nurses, and experts in plastic and reconstructive surgery, orthopaedic surgery, anesthesiology, and radiology. According to Alexandra Sifferlin at TIME, the team was split into four groups on the day, with two tending to Zion’s limbs, and two tending to the donor hands.

The bones in the hands and the limbs were connected first with steel screws and plates before the veins and arteries were linked up. Once the team managed to get the blood flowing from Zion’s limbs to his new hands, they transplanted the nerves, muscles, and tendons.

“This surgery was the result of years of training, followed by months of planning and preparation by a remarkable team,” Levin said in a press release. “The success of Penn’s first bilateral hand transplant on an adult, performed in 2011, gave us a foundation to adapt the intricate techniques and coordinated plans required to perform this type of complex procedure on a child. CHOP is one of the few places in the world that offer the capabilities necessary to push the limits of medicine to give a child a drastically improved quality of life.”

Zion, who has two prosthetic legs, has spent the past few weeks getting used to his new hands, and as you can see in the video below, they look perfect. He’s able to grip things with them already, and is undergoing rigorous hand therapy several times per day to improve function. And something tells me his request for a puppy won’t go unfulfilled for long, because how can you say no to such a brave kid? We wish him all the best.

This lamp runs on a glass of water and two teaspoons of salt .

It can even charge your phone.

An engineering start-up called SALt has invented a lamp that burns for eight hours at a time, running on nothing but a glass of water and two teaspoons of salt. Named the SALt (Sustainable Alternative Lighting) lamp, the device will also be able to generate enough energy to charge a smartphone via the USB port, while also lighting up the room.

The lamp was invented in response to the fact that, right now, there are about 1 billion people in the world who are living without electricity. This means if they want to get anything done after dark, whether it’s walking home from school or work, or doing homework, reading, or cooking at night, they have to light their way with dangerous and expensive kerosene lamps.

The SALt lamp works with a galvanic cell battery, which consists of an electrolyte solution – the salt and water – and two electrodes. When the electrodes are placed in the electrolyte, the energy generated kicks an LED light into gear. According to the developers, the battery will work for eight hours a day for six months, which is a considerable upgrade from the constant refills required by paraffin lantern.

As the majority of the Philippines’ 7,000 islands are yet to acquire electricity, the team at SALt decided to initially distribute their lamps to indigenous Filipino communities for wider testing. The design is perfect for these coastal communities, because it works with pure seawater, as the team explains on the website:

“The salinity of ocean water can operate your lamp. Use the ocean-water to power up your lamp and it will give you eight hours of running-time. Salinity is expressed by the amount of salt found in 1,000 grams of water. The average ocean salinity is 35 parts per thousand. Store ocean water in bottles and use them to power up you lamp anytime, anywhere.”


The team hopes to get the lamp on the market by 2016, but they’ll have some stiff competition with a similar invention also in the works – the GravityLight, which runs simply on the force of gravity. As Fiona MacDonald reported for us earlier this year, the lamp works a bit like a tiny pulley – all you need to do is add 12 kg of weight to one end of the bead cord, which could be a bag of sand or rocks, for example, and then lift that weight up by pulling down on the lamp that’s attached to the other end.

“Thanks to gravity, the weight slowly descends back down to the floor, transforming potential energy into kinetic energy as it drops,” she says. “This kinetic energy then powers a drive sprocket and polymer gear train that lights up the LED as it goes. Once the weight gets to the floor, the light goes out and you need to repeat the process, but each pull provides you around 20 to 30 minutes of light, depending on how high you lift the weight up in the first place.”

We love inventions like this. While of course we should be focussing on getting electricity to far more communities than currently enjoy it, cheap and innovative devices like this are greatly needed in the interim.

Scientists have finally discovered massless particles, and they could revolutionise electronics .

They can theoretically carry charge 1,000 times faster than ordinary electrons.

After 85 years of searching, researchers have confirmed the existence of a massless particle called the Weyl fermion for the first time ever. With the unique ability to behave as both matter and anti-matter inside a crystal, this strange particle can create electrons that have no mass.

The discovery is huge, not just because we finally have proof that these elusive particles exist, but because it paves the way for far more efficient electronics, and new types of quantum computing. “Weyl fermions could be used to solve the traffic jams that you get with electrons in electronics – they can move in a much more efficient, ordered way than electrons,” lead researcher and physicist M. Zahid Hasan from Princeton University in the US told Anthony Cuthbertson over at IBTimes. “They could lead to a new type of electronics we call ‘Weyltronics’.”

So what exactly is a Weyl fermion? Although we’re often taught in high school science that the Universe is made up of atoms, from a particle physics point of view, everything is actually made up of fermions and bosons. Put very simply, fermions are the building blocks that make up all matter, such as electrons, and bosons are the things that carry force, such as photons.

Electrons are the backbone of today’s electronics, and while they carry charge pretty well, they also have the tendency to bounce into each other and scatter, losing energy and producing heat. But back in 1929, a German physicist called Hermann Weyl theorised that a massless fermion must exist, that could carry charge far more efficiently than regular electrons.

And now the team at Princeton has shown that they do indeed exist. In fact, they’ve shown that in a test medium, Weyl electrons can carry charge at least 1,000 times faster than electrons in ordinary semiconductors, and twice as fast as inside wonder-material graphene.

They’re also far more efficient than electrons, the team reports in Sciencebecause the particle’s spin is both in the same direction as its motion (which physicists call ‘right-handed) and opposite its direction (‘left-handed’) at the same time. This means that all the fermions move in exactly the same way and can traverse through and around obstacles that scatter normal electrons.

“It’s like they have their own GPS and steer themselves without scattering,” Hasan said in a press release. “They will move and move only in one direction since they are either right-handed or left-handed and never come to an end because they just tunnel through. These are very fast electrons that behave like unidirectional light beams and can be used for new types of quantum computing.”

What’s particularly cool about the discovery is that the researchers found the Weyl fermion in a synthetic crystal in the lab, unlike most other particle discoveries, such as the famous Higgs boson, which are only observed in the aftermath of particle collisions. This means that the research is easily reproducible, and scientists will be able to immediately begin figuring out how to use the Weyl fermion in electronics.

The team found the particle after specially formulating a semi-metal crystal called tantalum arsenide, which had previously been flagged by researchers in China as a potential ‘home’ for the Weyl fermion. After finding traces of the elusive particle in their lab, they took the crystals to the Lawrence Berkeley National Laboratory in California, where they fired high-energy photon beams through them. The signature of the beams on the other side confirmed that the crystals did indeed contain the Weyl fermion.

Weyl fermions are what’s known as quasiparticles, which means they can only exist in a solid such as a crystal, and not as standalone particles. But further research will help scientists work out just how useful they could be. “The physics of the Weyl fermion are so strange, there could be many things that arise from this particle that we’re just not capable of imagining now,” said Hasan.

We can’t wait to find out.

Pollution-Eating Tower Would Turn Smog Into Rings And Cufflinks

Each cube, ring or cufflink cleans about 35,000 cubic feet of air.

Once you suck smog out of the air, what should you do with it? Pollution particles are mostly made up of carbon, so Dutch Artist Daan Roosegaarde decided to compress them into jewelry in a nod to diamond, carbon’s sparkliest allotrope.

The device extracting this pollution powder is Studio Roosegaarde’s Smog Free Tower, a 23-foot-tall air purification system meant to clean up parks and other public spaces. The company launched a Kickstarter on July 22 with a goal of $54,000 to build a prototype, and so far it is well on its way to meeting that goal. The first tower will be showcased in Rotterdam, Netherlands in September and hopefully expand to other cities after that, according to theproject page.

Roosegaarde was also behind a project to create glowing smart roadsthat save energy and money by turning out the street lights, and a 45-meter-wide rainbow serving as a physics art installation.

The technology powering the Smog Free Tower is based on air-purification systems in hospitals, just at a larger scale. The tower will produce 3,500 smog cubes per day if it’s in an area with a lot of air pollution, and each one of the cubes cleans over 35,000 cubic feet of air — ideally translating to nearly 123 million cubic feet of clean air per day. The Kickstarter campaign is offering cubes, rings and cufflinks to its supporters, which cost about $54 for a cube and $271 for the jewelry.

To make the cubes, each tower would use about 1,700 watts of energy from non-renewable sources–but Roosegaarde says can come from solar eventually.


How Big Pharma gets away with injecting children with neurotoxic heavy metals.

The systematic takedown of medical freedom in the U.S. certainly didn’t happen overnight, but the disastrous fallout that we see today might appear that way. How did our once great republic degenerate from every citizen possessing an inalienable right to treat his own body how he best sees fit to parents now being mocked, manipulated and coerced at every turn into injecting their babies with neurotoxic chemicals and live viruses in the name of health promotion and disease prevention?

The vaccine industry’s influential power over national health policy has been swelling for many decades, having been birthed largely out of 1930s cannabis prohibition and the early days of the “war on drugs.” A major paradigm shift occurred during this pivotal time in U.S. history that paved the way for the establishment of a centralized pharmaceutical industry, including an entire industry devoted to developing artificial immunity jabs, or what are more commonly known as vaccines.

Since that time, the vaccine industry has gained key inroads into the American political structure that have allowed it to attain an all-powerful status. The vaccine industry is the only sector of the general economy that is exempt from the normal legal process, for example, meaning vaccine recipients and their families can’t sue vaccine manufacturers when they’re injured or killed by vaccines. Vaccines are also given unwavering rubber-stamp approval by the mainstream media as being “safe and effective,” despite the fact that no independent, long-term safety studies have ever been conducted to prove this.

Back in the 1980s when the autism epidemic first became evident, pharmaceutical and vaccine companies switched into high gear to co-opt the media, the medical establishment and the government to protect the reputation of vaccines. So-called regulatory agencies such as the Centers for Disease Control and Prevention (CDC), the Food and Drug Administration (FDA), the National Institutes of Health (NIH) and various others all jumped aboard.

Then, in 1996, the pharmaceutical drug cartel successfully lobbied (bribed) Congress into allowing direct-to-consumer advertising of prescription drugs, all the while muzzling the corporate media to avoid any talk linking vaccines to autism. Thousands of parents of vaccine-injured children have also been silenced in the process, and increasingly so as the idea of compulsory vaccinations floats through the headlines as the next plank in converting the entire world to the religion (cult) of vaccines.

It was former President Ronald Reagan who signed NCVIA into law exempting vaccine corporations from liability for vaccine injuries

Interestingly enough, conservative icon and former President Ronald Reagan, whom many champions of liberty hold in high esteem, was the one responsible for getting vaccine companies off the hook when it comes to liability for vaccine damage. Back in 1986, Reagan signed the National Childhood Vaccine Injury Act, or NCVIA, absolving drug companies from all liability for vaccine injuries.

“No vaccine manufacturer shall be liable… for damages arising from a vaccine-related injury or death,” stated former President Reagan as he signed NCVIA into law.

Keeping a lid on the truth has proven difficult, however, especially as the U.S. government, using taxpayer dollars, has forked out some $3 billion in damages to vaccine-injured families over the past few decades through NCVIA. Vaccine manufacturers haven’t been held liable, of course, but this roundabout admission of guilt that their products injure and kill children is now in public purview, despite all the propaganda to the contrary.

“Aluminum, as is mercury, is a known potent mitochondrial toxin, and every cell in the body, especially the brain cells of infants, is highly susceptible to permanent damage from those two heavy metals, especially when they are used in combination and especially when they are injected — as was the case during the 1990s when the autism epidemic was escalating from rare (1/10,000 [sic] to ‘normal’ (1/150),” wrote Dr. Gary G. Kohls for the Centre for Research on Globalization.

University Professor Says Ebola is a Genetically Modified, Lab-Made Virus

University Professor Says Ebola is a Genetically Modified, Lab-Made Virus.

University Professor Says Ebola is a Genetically Modified, Lab-Made Virus

In a recently released report titled “Estimating Ebola Treatment Needs, United States,” the CDC is still playing down its latest round of fear-mongering for the virus which was “meant to infect every man, woman, and child in the US.” To date, and by their own admission there have been only 10 cases in the entire U.S.

How disappointing for the makers of the Ebola vaccine. Especially when publications like the Liberian Observer, in a piece by Dr. Cyril Broderick, expose how its “likely manufactured by Big Pharma.”

Dr. Cyril Broderick is a former professor of plant pathology at the University of Liberia’s College of Agriculture and Forestry, and is on tenure as an associate at Delaware University.
Broderick claims that the Ebola virus which recently ran rampant in Western Africa was genetically modified, made in a lab by Western pharmaceutical companies, and administered to unsuspecting civilians through United Nations vaccination programs. The Washington Post called it a wild conspiracy theory, but is there actually truth to these shocking allegations?

The truth is in this video. Dr. Broderick references Dr. Leonard Horowitz in the Liberian Observer article. He presents substantial evidence which explains this tidbit:

“[Horowitz]. . .unearthed and reprinted stunning scientific documents and National Institutes of Health contracts proving that chimpanzees, contaminated with numerous viruses, were used to produce hundreds of hepatitis B vaccine doses administered to central African Blacks along with homosexual men in New York City at precisely the time Dr. Myers and colleagues claim the origin of HIV ‘punctuated event’ occurred.”
Some are saying that not only was the HIV virus likely man-made, but so was Ebola. Who knows which other pandemic diseases are created so the mainstream medical system can profit from them.
