New Subtle Energy Pattern Research Shows Increases in Cell Growth and Viability
Posted: January 13, 2015 at 4:47 pm
White City, OR (PRWEB) January 13, 2015
Groundbreaking new results show targeted subtle energy patterns, sometimes referred to as bioenergetic patterns, have a significant positive impact on human cell growth and mitochondrial membrane potential. Three notable findings include an 83% increase in cell viability under food deprivation conditions, a 50% increase in mitochondrial longevity in the presence of toxins and third of all, that mitochondria exposed to subtle energy and under starved and poisoned conditions showed increased viability over even the non-poisoned control. These recent findings show potential long term improvement to human cell viability which can slow and reverse the breakdown of human cells.
Cell growth experiments at Beech Tree Labs tested human dermal fibroblasts (HDF) infused with one of four unique, proprietary subtle energy patterns from Vital Force Technology; Cell Longevity, Peak Performance, Stress Relief, and Anti-Cancer. The experiment compared the influence of different subtle energy patterns on cell viability and longevity. It was found that cells growing with subtle energy pattern Stress Relief had 83% more live cells remaining on the 9th day than the control group. Additionally, those groups infused with Cell Longevity and Peak Performance yielded 50% more live cells on the 9th day than found in the control.
At Rigas University in Latvia researchers looking into mitochondrial viability and longevity tested Cell Longevity, and Peak Performance energy patterns on human embryonic kidney cells. After three days, stressed cells exposed to the subtle energy patterns showed increased viability over the control groups. Meaning, the stressed cells exposed to subtle energy showed more mitochondrial longevity than the cells that were never stressed to begin with.
Ultimately both Beech Tree Labs and Rigas findings hint at new possibilities that could have major implications for human health and may be the first step towards a completely non-toxic, natural, and no side effect alternative to traditional health treatments. The full study along with other studies can be reviewed in the research section of the Vital Force Technology website at http://vitalforcetechnology.energytoolsint.com/results/research/cellular/

$1 Million Prize to Extend Human Life Beyond 120
Posted: at 8:47 pm
London: A Silicon Valley entrepreneur has launched a $1 million prize challenging scientists to discover the 'elixir of life' and push human lifespan past its apparent maximum of about 120 years.
Fifteen scientific teams have so far entered the prize to find the elusive fountain of youth.
According to hedge fund manager Dr Joon Yun, the chance of dying between ages 25 and 26 is only 0.1 per cent.
He now wants scientists to "hack the code of life" and push human lifespan past its apparent maximum of about 120 years, the Guardian reported.
Dr Yun believes it is possible to "solve aging" and get people to live, healthily, more or less indefinitely.
Dr Yun plans to offer more money for feats above and beyond until longevity is no longer an "issue."
Dr Yun is not the only one who sees a new flowering of anti-aging research.
In 2013, Google launched California Life Company (Calico) with a mission to reverse engineer the biology that controls lifespan and "devise interventions that enable people to lead longer and healthier lives."
In 2014, pioneering American biologist and technologist Craig Venter along with the founder of the X Prize Foundation, Peter Diamandis, announced a new company called Human Longevity Inc.
The company plans to create a database of 1 million human genome sequences by 2020 that will give key information for a longer, healthier life.

200-Year-Old Whale May Give Clues to Human Longevity
Posted: January 8, 2015 at 3:46 am
Latest Senior Health News
TUESDAY, Jan. 6, 2015 (HealthDay News) -- A whale that lives more than 200 years with no signs of age-related disease may give scientists new insight on how people can live longer, healthier lives, a new study finds.
For the first time, British researchers have completed the genetic map ("genome") of a large whale -- the bowhead whale. In doing so, they spotted key differences between the genome of the bowhead whale and other mammals.
Changes in the bowhead's genes tied to aging, cell division, cancer and DNA repair may all play a role in why the whales live so long, according to the study published Jan. 6 in Cell Reports.
"Our understanding of species' differences in longevity is very poor, and thus our findings provide novel candidate genes for future studies," study senior author Dr. Joao Pedro de Magalhaes, of the University of Liverpool, said in a journal news release.
"My view is that species evolved different 'tricks' to have a longer lifespan, and by discovering the 'tricks' used by the bowhead we may be able to apply those findings to humans in order to fight age-related diseases," he added.
The researchers pointed out that large whales like the bowhead have more than 1,000 times more cells than people, and yet they appear to be resistant to cancer. This suggests that these whales may have a natural defense mechanism that suppresses cancer more effectively than other mammals, they said.
Looking ahead, the study authors hope to breed mice with certain bowhead whale genes to determine which are important for longevity and resistance to disease.
The whale genome may also help identify certain adaptations related to the large mammal's size, such as a much lower metabolic rate.

Whale genes clue to reverse human aging
Posted: January 6, 2015 at 9:45 pm
Reuters
WHAT'S THEIR SECRET?: Bowhead whales are said to live for more than 200 years with low rates of disease.
Bowhead whales are most likely the longest-living mammals on the planet. There's evidence - some of it in the form of Victorian-era harpoons embedded in blubber - that they can live as long as 200 years. And there are humans who'd like to get a little slice of that longevity for themselves.
This week, some of them took the first step to stealing the bowhead whale's secrets: they sequenced its genome. Their results have now been published in biomedical research journal Cell.
"I think that having the genome sequence of the bowhead whale will allow researchers to study basic molecular processes and identify maintenance mechanisms that help preserve life, avoid entropy and repair molecular damage," said corresponding author Joao Pedro de Magalhaes of the University of Liverpool.
Most research experiments try to model human decay and disease in other animals to learn how to cure it, Magalhaes said. But he hopes he can find organisms that are resistant to certain diseases - and to some extent, perhaps even aging itself - and use those tools to better human health.
Of particular interest is the whales' resistance to cancer. The species can weigh as much as 100 tons, and has thousands of times more cells than a human. So statistically, it would make sense for the whales to exhibit more instances of cancer. But examination hasn't found this to be so.
Magalhaes and his colleagues did find differences between bowhead whales and minke whales (close relatives who only live about 50 years) in genes related to cell cycle, DNA repair, cancer and aging. He believes that bowhead whales may be better at repairing DNA damage, which would keep them alive longer and protect them from diseases like cancer.
But Magalhaes didn't find any important genes in common with the other long-living mammal he's sequenced, the naked mole rat. "Some pathways may be in common in long-lived species, like DNA damage responses, but the specific genes involved seem to be different," he said.
He believes that these two species each work with their own bag of evolutionary tricks - and he hopes that humans could borrow a few of them.

Bowhead Whale Genome May Hold Clues To Human Longevity
Posted: at 9:45 pm
The secret to anti-aging may lie in the genes of a particularly robust whale species. Bowhead whales can reach 200 years of age and are the longest living mammal on earth. They spend their lives relatively disease-free, including from cancer, a fact that scientists say could prove useful in studies on human longevity. Researchers from the University of Liverpool in the United Kingdom sequenced the whales genome for the first time and identified certain mutations in genes involved in DNA repair, aging and cell maintenance that may contribute to the whales endurance, a study published Monday in the journal Cell Reports indicated.
"We believe that different species evolved different 'tricks' to have a long lifespan, and by discovering those used by the bowhead whale we may be able to apply these findings to humans in order to fight age-related diseases, Joo Pedro de Magalhes, a geneticist and lead author of the study, said in a statement. The team found as many as 80 genes in the whales DNA that could play a role in keeping cancer and other diseases at bay. He added pinpointing new candidate genes in mammal species could even lead to new drug therapies.
Scientists have long been in search of the proverbial fountain of youth. Previous research has shown while all humans certainly age, not everyone ages at the same rate. Some peoples cells deteriorate faster than those of others, Timereported in 2010. The reason, scientists have claimed, has to do with a persons telomeres, the bits of DNA that protect the bodys chromosomes -- the thread-like molecules contain all genetic data. Telomeres are often likened to the plastic tips at the end of shoelaces. Every time a cell replicates itself, these telomeres fray or shorten. The shortening process has been linked with aging and age-related diseases like cancer and heart disease, according to the Genetic Science Learning Center at the University of Utah in Salt Lake City.
The key to slowing down an individuals biological clock may be controlling the length of the telomeres in a persons chromosomes, scientists have suggested. "We know DNA damage and DNA mutation are important for cancer, Magalhes told CBS News. So when we find genes related to DNA repair and DNA damage responses, we think maybe this could be involved in longevity and disease resistance of the bowhead. He described the whales genes as promising leads in the search for an anti-aging mechanism.
Bowhead whales are found in the Arctic and are among the planets largest creatures. Adult bowheads can weigh 75- to 100 tons.
Commercial whaling in the 19th and early 20th centuries drove their populations into the ground. By the 1920s, there were just 3,000 bowheads left worldwide, according to the National Oceanic and Atmospheric Administrations Office of Protected Resources. Their population today is estimated at more than 24,900 worldwide.
What surprised scientists most about the bowhead was that even with about 1,000 times as many cells as humans, the whales probability of developing cancer and other age-related diseases was significantly lower. One genetic mutation involved a gene called ERCC1, which helps repair damaged DNA and may help the whale fend off cancer. Researchers also found a mutation in a gene called UCP1, which helps regulate metabolism.
These differences suggest "the existence of natural mechanisms that can suppress cancer more effectively in these animals, researchers wrote in their report. Studying these differences in more detail could help researchers identify maintenance mechanisms that help preserve life, avoid entropy, and repair molecular damage.

Study: Bowhead Whale Genome May Hold Secret to Longevity
Posted: January 5, 2015 at 6:43 pm
The Bowhead whale may harbor the secret to longevity, according to a new study that describes its genome.
Native to the Arctic, the bowheadis big and strong and can live 200 years, possibly the longest lifespan of any mammal. But why does it live so long? That question has intrigued University of Liverpool scientist Joao Pedro Magalhaes for a long time.
Why do human beings age slower than other primates?" he says. "Why do mice age so much faster than humans or whales? And likewise, why do bowhead whales seem to live longer than human beings and seem to be protected against some age-related disease like cancer?
Magalhaes says this remains a mystery. But in sequencing the genome, the scientists looked for patterns comparing the bowhead to other closely related, but shorter-lived species, such as the Minke whale. Magalhaes says the team focused on identifying genes with bowhead specific mutations.
We looked for genes that are duplicated that is, they have multiple copies in the bowhead whale, but not in other related species. And this revealed a number of promising leads.
In the journal Cell Reports, Magalhaes and colleagues describe alterations in bowhead genes related to cell division, DNA repair, cancer and aging. Magalhaes says different long-lived species use different tricks to evolve a long life span. He wants to uncover the natural mechanism that triggers that process.
If I can figure out what are these tricks in the bowhead and what makes them live so long and protects against diseases, we can then try to apply them to human beings, which could involve pharmacological interventions or pharmacological targeting of particular genes," he said. "It could involve gene therapy.
The next step, he says, is to breed mice with bowhead whale genes, to determine the importance of different longevity and age-related mutations. But the sequence has other applications, too: understanding population dynamics and genetic diversity can help conservationists working to protect the species, which is threated by habitat loss and toxins in the environment.
