SUPPORTERS of vaping claim it is a way for smokers to quit and it is also a “lesser evil” than conventional cigarettes.

But new research suggests vaping increases the level of DNA-damaging compounds. If cells cannot repair DNA damage the risk of cancer can increase, say scientists.

The study analysed the saliva and mouth cells of five e-cigarette users before and after a 15-minute vaping session. Researchers found increased levels of toxic chemicals formaldehyde, acrolein and methylglyoxal

Study: Lead and Other Toxic Metals Found in E-Cigarette ‘Vapors’

 

POTENTIALLY DANGEROUS LEVELS OF METALS LEAK FROM SOME E-CIGARETTE HEATING COILS

Significant amounts of toxic metals, including lead, leak from some e-cigarette heating coils and are present in the aerosols inhaled by users, according to a study from scientists at Johns Hopkins Bloomberg School of Public Health.

In the study, published online in Environmental Health Perspectives on February 21, the scientists examined e-cigarette devices owned by a sample of 56 users. They found that significant numbers of the devices generated aerosols with potentially unsafe levels of lead, chromium, manganese and/or nickel. Chronic inhalation of these metals has been linked to lung, liver, immune, cardiovascular and brain damage, and even cancers.

The Food and Drug Administration has the authority to regulate e-cigarettes but is still considering how to do so. The finding that e-cigarettes expose users—known as vapers—to what may be harmful levels of toxic metals could make this issue a focus of future FDA rules.

“It’s important for the FDA, the e-cigarette companies and vapers themselves to know that these heating coils, as currently made, seem to be leaking toxic metals—which then get into the aerosols that vapers inhale,” says study senior author Ana María Rule, PhD, MHS, an assistant scientist in the Bloomberg School’s Department of Environmental Health and Engineering.

      Is this Elephant ? Smoking? No they feel just like other birds and animals the grounds contain ash or charcoal that helps the digestive system. How do they know that? A all-wise Creator Jehovah God! 
      #OurCreatorJehovahGod??
      .
      Why does this elephant appear to be blowing out a cloud of smoke? @TheWCS scientists are scratching their heads. The video was captured by Vinay Kumar of @wcsindia. He and some colleagues were visiting camera traps that had been set up to study tigers and their prey in Nagarahole National Park when they stumbled on the elephant. “I believe the elephant may have been trying to ingest wood charcoal,” said Dr. Varun Goswami, an elephant biologist with WCS India. “She appeared to be picking up pieces from the forest floor, blowing away the ash that came along with it, and consuming the rest.” Charcoal has toxin-binding properties that may provide medicinal value. It can also serve as a laxative, thereby doubling its utility for animals that consume it after forest fires, lightning strikes, or controlled burns.

      Electronic cigarettes, the popular vapor substitute to traditional tobacco cigarettes, will soon be banned from public indoor spaces in New York State — just like the real thing.
      Gov. Andrew M. Cuomo on Monday signed a bill to ban vaping anywhere cigarettes are already prohibited, like workplaces, restaurants and bars. The ban goes into effect in 30 days.
      E-cigs, as the products that vaporize a variety of oils into an inhalant are generally known, were added to the state’s Clean Indoor Air Act this summer by the State Assembly, and the measure was approved by the Senate. The original act has been around since 2003, when smoking tobacco products in public indoor areas was first banned in the state, one of the country’s first such measures.

      According to researchers of the Jewish culture, the human gene would have the signature of the name of God, with the 4 letters of the Tetragrammaton.(Yod) ה (heh) ו (vav) ה (heh), Tetragrammaton .....Hey vau, = 5 = 6, beats = 5;10 + 5 + 6 + 5
      But the TV showed scientific research mixed with Jewish cabal research. These are theories that involve data from scientists mixed with Kabbalah, tradition, Jewish philosophy,,Not trustworthy. Part of the report is serious, but when it moves to Jewish tradition and philosophy, it took the credibility of part of the report,.
      Scientists are questioning the origin of life and show the existence of a higher being. A new line of research, known as intelligent design, believes that the complexity of life and perfection of nature prove the existence of a higher being. At the core of research in science, faith and society, newly opened by one of the largest universities in São Paulo, in partnership with American institutions, scholars discard the creation of the world with a simple chance and analyze genetic codes as a sort of ' signature God '.

      E-cigarette Basics
      E-cigarettes are devices that heat a liquid into an aerosol that the user inhales. The liquid usually has nicotine and flavoring in it, and other additives. The nicotine in e-cigarettes and regular cigarettes is addictive. E-cigarettes are considered tobacco products because most of them contain nicotine, which comes from tobacco.
      Besides nicotine, e-cigarettes can contain harmful and potentially harmful ingredients, including:
      ultrafine particles that can be inhaled deep into the lungs flavorants such as diacetyl, a chemical linked to serious lung disease volatile organic compounds heavy metals, such as nickel, tin, and lead  
      E-cigarettes and Youth Don't Mix
      Adolescent years are times of important brain development. Brain development begins during the growth of the fetus in the womb and continues through childhood and to about age 25. Nicotine exposure during adolescence and young adulthood can cause addiction and harm the developing brain.
      Nicotine affects brain development, which continues to age 25.
      Trends
      E-cigarettes are very popular with young people. Their use has grown dramatically in the last five years. Today, more high school students use e-cigarettes than regular cigarettes. The use of e-cigarettes is higher among high school students than adults.
      E-cigarettes Are Unsafe for Young People
      No matter how it's delivered, nicotine is harmful for youth and young adults. E-cigarettes typically contain nicotine as well as other chemicals that are known to damage health. For example, users risk exposing their respiratory systems to potentially harmful chemicals in e-cigarettes. Read about these and other risks young people face if they use e-cigarettes.
      Talk with Your Kids
      You can influence your children's decision about whether to use e-cigarettes. Even if you have used tobacco yourself, your children will listen if you discuss your struggles with nicotine addiction. Be clear that you don't approve of them smoking or using e-cigarettes, and that you expect them to live tobacco-free.
      Use CDC's Parent Tip Sheet to help you talk with your children. This tip sheet offers facts and practical ways to start conversations with young people about the risks of e-cigarette use.

      Experts welcome news of successful mitochondrial transfer but caution against operating in countries beyond regulations

      The world’s first baby to be born from a new procedure that combines the DNA of three people appears to be healthy, according to doctors in the US who oversaw the treatment.
      The baby was born on 6 April after his Jordanian parents travelled to Mexico where they were cared for by US fertility specialists.
      Doctors led by John Zhang, from the New Hope Fertility Center in New York, decided to attempt the controversial procedure of mitochondrial transfer in the hope that it would give the couple a healthy child.
      While many experts welcomed news of the birth, some raised concerns that the doctors had left the US to perform the procedure beyond the reach of any regulatory framework and without publishing details of the treatment.
      Speaking to the New Scientist, Zhang said he went to Mexico where “there are no rules” and insisted that doing so was right. “To save lives is the ethical thing to do,” he said.
      Mitochondrial transfer was legalised in the UK in 2015 but so far no other country has introduced laws to permit the technique. The treatment is aimed at parents who have a high risk of passing on debilitating and even fatal genetic diseases to their children.

      The boy’s mother carries genes for the fatal Leigh syndrome, which harms the developing nervous system. The faults affect the DNA in mitochondria, the tiny battery-like structures that provide cells with energy, and are passed down from mother to child.
      Ten years after the couple married, the wife became pregnant but she lost the baby in the first of four miscarriages. The couple had a baby girl in 2005 who died at the age of six, and later, a second child who lived for only eight months. Tests on the wife showed that while she was healthy, about one-quarter of her mitochondria carried the genes for Leigh syndrome.
      When the couple approached Zhang for help, he decided to try the mitochondrial transfer procedure. He took the nucleus from one of the woman’s eggs and inserted it into a healthy donor’s egg that had had its own nucleus removed. He then fertilised the egg with the husband’s sperm.
      The US team created five embryos but only one developed normally. This was implanted into the mother and the baby was born nine months later.
      The baby is not the first child to be born with DNA from three people. In the 1990s, fertility doctors tried to boost the quality of women’s eggs by injecting cytoplasm, the cellular material that contains mitochondria, from healthy donor eggs. The procedure led to several babies being born with DNA from the parents plus the healthy donor. Some of the children developed genetic disorders and the procedure was banned.
      Speaking about the latest case, Dusko Ilic, a stem cell scientist at King’s College London, said: “Without much ado, it appears the first mitochondrial donation baby was born three months ago. This was an ice-breaker. The baby is reportedly healthy. Hopefully, this will tame the more zealous critics, accelerate the field, and we will witness soon the birth of the first mitochondrial donation baby in the UK.”
      But some questions remained, he said. “By performing the treatment in Mexico, the team were not subject to the same stringent regulation as some other countries would insist on. We have no way of knowing how skilful or prepared they were, and this may have been a risky thing to do.
      “On the other hand, we have what appears to be a healthy baby. Because it was successful, fewer questions will be raised, but it is important that we still ask them.
      “Was this the first time ever they performed the technique or were there other attempts and they are reporting this one because it was successful?
      “This and other important questions remain unanswered because this work has not been published and the rest of the scientific community has been unable to examine it in detail. It’s vital that that happens soon.”
      Alison Murdoch, a fertility doctor at Newcastle University, said: “If this baby has been born as suggested then that would be great news. The translation of mitochondrial donation to a clinical procedure is not a race but a goal to be achieved with caution to ensure both safety and reproducibility.”
      Details of the birth are due to be presented at the American Society for Reproductive Medicine meeting in Salt Lake City in October. 
      Doug Turnbull, a neurology professor at Newcastle University who pioneered mitochondrial transfer in the UK, said the technique offered hope to mothers who carried mitochondrial DNA mutations.
      “There have been extensive discussions in the UK to ensure that families with mitochondrial disease get the best possible advice about their reproductive options and that any new IVF-based technique is appropriately regulated and funded. This abstract gives very little information about the technique used, the follow up of the child or the ethical approval process.”
      This article was amended on 27 September 2016 to remove the names of some of the parties involved, because information changed about whether permission to name had been given.

      Evolutionary teachings hold that all mankind arose from a population of ape-like ancestors from which chimpanzees also evolved. But Genesis, the rest of the Bible, and Jesus teach that all mankind arose from Noah's three sons and their wives. A new analysis of human mitochondrial DNA exposes two new evidences that validate the biblical beginnings of mankind.
      Mitochondrial DNA comes from mothers. Mother egg cells transmit their mitochondrial DNA (mtDNA) into the cellular mitochondria of every child born. This unique annex of DNA contains 16,569 bases—either adenine, guanine, cytosine, or thymine (A, G, C, T)—that encode vital cellular information, like an instruction manual.
      Scientists have been comparing the genetic differences between every major people group around the globe. How did those differences arise?
      Assuming that God placed the ideal mtDNA sequence into Eve, all those differences arose by mutations since the Genesis 3 curse, about 6,000 years ago. Other scientists measured the rate at which these copying errors occur. Though very slow—we acquire about one mutation every 6 generations—a few dozen mutations could appear after several millennia.
      This sets the stage for researchers to compare competing models' predictions against measured mtDNA differences.
      Bible-believing molecular biologist Dr. Nathaniel Jeanson downloaded publicly available human mitochondrial genome sequence data to do exactly that. Publishing in Answers Research Journal, his results show that the number of today's mtDNA differences exactly matches the number predicted by the Bible's 6,000 years of human history.1 Mitochondrial DNA from around the world shows no trace of the 200,000 or so years' worth of mutations that the evolution model predicts.
      Geneticists construct tree diagrams using software that places the most similar genetic sequences near one another, and the most dissimilar sequences on the longest branches. Jeanson found at least two distinct patterns in the human mtDNA tree diagram that confirm Genesis.
      The center of the diagram shows three main trunks. Each reflects a specific mtDNA sequence with only a handful of differences from the other two.
      Could these three trunks represent the unique mtDNA from the wives of Shem, Ham, and Japheth?
      A second pattern emerges that also fits the three wives explanation. Assuming longer times between each generation, according to the biblical record of lifespans before the Flood, and using today's slow mutation rate, the 1,656 years between Adam and Noah would have produced the small number of differences that the short lines between each trunk represent.
      Jeanson compared the small number of mtDNA differences between each trunk, or central node, with the relatively large number of differences in the branches. He wrote, "About 1,660 years passed from Creation to the Flood, whereas 4,365 years passed from the Flood to the present—a ~2.6:1 time ratio. Consistent with this, the branches connecting the nodes to one another were much shorter than the branches spraying out from the nodes—as if the short branches represented pre-Flood mutations, and the long branches represented post-Flood mutations."1
      It appears that modern genetics confirms Genesis, which says, "So Noah went out, and his sons and his wife and his sons' wives with him."
      This study produced two Genesis-confirming results. First, the human mtDNA tree has three trunks, which fits the Genesis model that all peoples descended from three foundational mothers—the wives of Shem, Ham, and Japheth. Second, 6,000 years of today's slow mutation rate would exactly produce today's measured number of mtDNA differences. Genetics again confirms Genesis.

      What could be more alien than a virus? It’s a nanobiological weapon — a microscopic protein shell holding a few genes that hijack a cell’s internal machinery, forcing it to make new viruses. The battles we fight with these alien enemies brings malaise, scars and even death.
      Yet as foreign as viruses may seem, the boundary between us and them is turning out to be remarkably blurry. We use DNA from viruses to do things that are essential to our own survival, scientists are finding. Somehow, we have managed to domesticate some of these invaders.
      A number of viruses replicate by inserting their DNA into our own genes. On rare occasions, their genes get passed down to future generations.
      At first, the newly acquired genes behave a lot like regular virus genes. They can still coax host cells to make full-fledged viruses that can escape and infect other victims.
      But over the generations, they lose the ability to escape human cells. They can still make copies of themselves, but those copies get incorporated into the host cell’s DNA. Over time these so-called endogenous retroviruses lose even the ability to replicate, becoming harmless fragments adrift in the human genome.
      Endogenous retroviruses first invaded the cells of our primate ancestors more than 50 million years ago. Scientists have identified over 100,000 of these fragments in the human genome, accounting for 8 percent of our DNA.
      Some of these fragments have become part of our biology and perform tasks that benefit us. “A host essentially takes over a viral gene and puts it to work for its own ends,” said Aris Katzourakis, an evolutionary biologist at the University of Oxford.
      Human cells may have even co-opted viral DNA for a particularly ironic purpose: to fight other viruses.
      Twenty years ago, British scientists investigated a virus-fighting protein called Fv1. It protects mice by latching onto invading viruses and preventing them from inserting their DNA into the genome of a mouse cell. The gene that encodes Fv1 came originally from a mouse-infecting virus, the researchers discovered.
      Other proteins produced by viral DNA block the receptors through which newcomer viruses invade. Some viral proteins disrupt the replication of attacking viruses, leaving them unable to invade other cells.
      On Thursday in the journal Science, scientists reported that human ancestors also harnessed viral DNA to rewire their own genetic circuitry.
      Guillaume Bourque, a geneticist at McGill University who was not involved in the study, praised it for revealing a new way in which evolution harnessed viral DNA to strengthen the immune system. “In that sense, it’s a first,” he said.
      To fight invading viruses, a cell needs to turn on many genes at once. The genetic switches that make this possible are stretches of DNA next to each gene, which are themselves activated by proteins.
      From left, University of Utah geneticists Cedric Feschotte, Edward Chuong and Nels Elde. Their research suggests that viral DNA fragments in the human genome may help fight viral infections.
      UNIVERSITY OF UTAH HEALTH SCIENCES
      One such protein is interferon, which is produced when a cell is attacked by a virus. Interferon turns on genes that cells use to defend themselves.
      Cedric Feschotte and his colleagues at the University of Utah wondered if our cells harnessed viral gene switches to turn on immune genes. They discovered many pieces of viral DNA sitting next to genes that belong to the interferon network.
      The scientists edited the DNA of human cells they grew in a dish, chopping out some of the viral switches near interferon-responsive genes. Then they exposed those cells to interferon. The immunity genes, they found, barely woke up.
      In another experiment, the team exposed the altered cells to viruses and found that the cells mounted only a weak defense. “They became more susceptible to infection,” Dr. Feschotte said.
      The results suggest that many of the gene switches that help defend our cells from viruses actually came from viruses.
      Dr. Feschotte noted that a number of viruses that infect humans today have gene switches that turn on their genes when they sense their host cells have launched an interferon defense. Such gene switches would have been easily captured by our own cells.
      The new study adds even more evidence of the importance of viral DNA in our evolution. By spreading their DNA around our genome, viruses provided us with new switches that our cells could harness.
      But understanding the full effect of viruses on our evolution will take years, according to Dr. Feschotte. “It’s the sort of thing that I think about night and day,” he said.
