  • What you eat, not just number of calories, is significant factor in diabetes risk

    If you think losing weight is enough to prevent Type 2 diabetes, don't get your hopes up. A new research report in September 2014 issue of The FASEB Journal, suggests that you don't have to be overweight to develop Type 2 diabetes. This study compared genetically identical twins-one heavier and one leaner-and found that after eating a fast-food meal, the circulating metabolites, including those related to Type 2 diabetes, were found in both individuals at the same levels. These findings suggest that the onset of this type of diabetes is largely influenced by genetic factors and/or the composition of gut...

    A genetic cause for homosexuality is not scientifically possible. A homosexuality gene, if it existed, would quickly die out. However, it gradually becomes clear that liberals and progressives are poorly-educated about science. They passionately believe in evolution, yet they don’t understand it. Public discussion is driven by an assumption that one may be “born homosexual.” Being ‘born’ homosexual is a medical impossibility unless there is a specific gene causing it. That is, heterosexuals would have one genetic DNA sequence while homosexuals have a different DNA sequence in its place. I discovered something debating this topic: One central point simply escapes...

    Back in March, I wrote a piece for CatholicVote about FDA evaluation of a process that would create multi-parent embryos: Things like this always begin for such seemingly noble scientific reasons, don’t they? But they rarely stop there. And of course in addition to creating tri-parent offspring, which creates ethical and genealogical nightmares in its own right, virtually every instance of embryonic modification involves a slew of violations of the moral law, from in-vitro fertilization to the destruction of fertilized human embryos — human life — deemed imperfect or unnecessary to achieve the desired outcome.

    DNA analysis has debunked the longstanding theory that the Minoans, who some 5,000 years ago established Europe's first advanced Bronze Age culture, were from Africa. The Minoan civilisation arose on the Mediterranean island of Crete in approximately the 27th century BC and flourished for 12 centuries until the 15th century BC. But the culture was lost until British archaeologist Sir Arthur Evans unearthed its remains on Crete in 1900, where he found vestiges of a civilisation he believed was formed by refugees from northern Egypt. Modern archaeologists have cast doubt on that version of events, and now DNA tests of...

    ‘New analyses of the human genome establish that human evolution has been recent, copious and regional,” writes Nicholas Wade in his recently published book A Troublesome Inheritance: Genes, Race and Human History. That sounds reasonable, and Wade, a science reporter and editor for many years at Nature and the New York Times, seems an unimpeachable source. But many well-meaning people will regard his words as provocative and even dangerous. For they fatally undermine the idea, widely shared by so-called progressives, that any apparent differences between groups of people are the product of nurture rather than nature, of social conditioning rather...

    CHICAGO – The results of a comprehensive scientific study released earlier this year suggest that homosexuality cannot be directly traced to a ‘gay gene,’ but is instead dependent on a variety of factors, including environmental and social influences. Pro-homosexual activists have long claimed that homosexuality and abnormal “sexual orientations” are primarily caused by genetic factors. They argue that individuals with a hereditary “gay gene” are predisposed toward same-sex attractions and thus unable to appreciate traditional marriages. However, scientific findings released earlier this year during the American Association for the Advancement of Science in Chicago call this premise into question. During...

    A Troublesome Inheritance: Genes, Race and Human History, by Nicholas Wade (Penguin Press, 288 pp., $27.95) In 2001, the New England Journal of Medicine published an editorial provocatively titled “Racial Profiling in Medical Research.” The author, Robert Schwartz, reiterated the commonly held view that no biological basis exists for race, and then argued that physicians should not consider race in their research or medical practice. This prompted a sharp response from geneticist Neil Risch, who pointed out that numerous studies had demonstrated significant genetic differences among humans based on continental ancestry, suggesting evidence of five distinct races. Among the reasons...

    Gawker published a piece on the neurological problems which might result in pedophilia, and naturally a lot of shock and disgust was triggered. The piece is titled Born This Way: Sympathy and Science for Those Who Want to Have Sex with Children. This isn’t something you want to click through to lightly. So fair warning. The neurobiological material did pique my interest: “There was nothing significant in the frontal lobes or temporal lobes,” says Cantor. “It turned out the differences weren’t in the grey matter. The differences were in the white matter.”“The white matter” is the shorthand term for groupings...

    Lady Gaga’s mega-hit song “Born this Way” sold millions of copies affirming what many people believe: homosexuality is hardwired. In fact, people think that’s as axiomatic as saying the earth revolves around the sun. No rational person rejects the idea. The only hold-outs, it is said, are either ignorant of science, homophobic, or bigots (read: Christians). But before I explain why this view is beset with problems, let me make a tactical suggestion. Many Christians get defensive when someone says homosexuality is inborn. I understand the temptation to argue against this claim. But it’s a mistake to try to show...

    ome 12,000 years ago, a teenage girl took a walk in what’s now the Yucatan Peninsula and fell 190 feet into a deep pit, breaking her pelvis and likely killing her instantly. Over time, the pit—part of an elaborate limestone cave system—became a watery grave as the most recent ice age ended, glaciers melted and sea levels rose. In 2007, cave divers happened upon her remarkably preserved remains, which form the oldest, most complete and genetically intact human skeleton in the New World. Her bones, according to new research published in Science, hold the key to a question that has...

If that’s the problem you have with transgenic plants, that’s not a good reason to be against them,” Vance says. She does, however, have a problem with mega corporations allegedly using their money and power to hide the risks of new forms of genetic technology....

    Sometime in the future, technicians will go over the scene of the crime. They’ll uncover some DNA evidence and take it to the lab. And when the cops need to get a picture of the suspect, they won’t have to ask eyewitnesses to give descriptions to a sketch artist – they’ll just ask the technicians to get a mugshot from the DNA. That, at least, is the potential of new research being published today in PLOS Genetics. In that paper, a team of scientists describe how they were able to produce crude 3D models of faces extrapolated from a person’s...

The breakthrough comes as a result of last year's discovery of an incredibly well-preserved mammoth carcass, frozen in the permafrost of Siberia's Malolyakhovskiy island. The scientists estimate that the animal is about 43,000 years old, and was 50-60 years old when it died in distress after getting stuck in the ice. In the ten months since...

When Brian Dias became a father last October, he was, like any new parent, mindful of the enormous responsibility that lay before him. From that moment on, every choice he made could affect his newborn son's physical and psychological development. But, unlike most new parents, Dias was also aware of the influence of his past experiences — not to mention those of his parents, his grandparents and beyond. Where one's ancestors lived, or how much they valued education, can clearly have effects that pass down...

The Food and Drug Administration has framed its two-day meeting as a "scientific, technologic and clinical" discussion about how to test the approach in humans. But the technique itself raises a number of ethical questions, including whether the government should sanction the creation of genetically modified humans.

For example, the DNA of the Tu people in modern China suggests that in around 1200 C.E., Europeans similar to modern Greeks mixed with an otherwise Chinese-like population. Plausibly, the source of this European-like DNA might be merchants travelling the nearby Silk Road."

Just because an argument is politically strategic, does not make it true: A couple of years ago, the Human Rights Campaign, arguably the country’s most powerful lesbian and gay organization, responded to politician Herman Cain’s assertion that being gay is a choice. They asked their members to “Tell Herman Cain to get with the times! Being gay is not a choice!” They reasoned that Cain’s remarks were “dangerous.” Why? “Because implying that homosexuality is a choice gives unwarranted credence to roundly disproven practices such as ‘conversion’ or ‘reparative’ therapy.

The gay brothers were identified and recruited to help with the study over the course of several years’ worth of Gay Pride festivals and marches.

    Being gay could be in the DNA. Scientists have found two stretches of DNA linked to homosexuality in men. The confirmation of the existence of a ‘gay gene’ or genes will strengthen arguments that homosexuality is a matter of biology, rather than choice. However, it also raises the prospect of a genetic test that could be used by insurance companies to discriminate against clients or by pregnant women to abort gay babies. In the study, Chicago University researchers analysed the DNA of more than 400 pairs of gay brothers, recruited at Gay Pride festivals at marches over several years. This...

UW scientists were stunned to discover that genomes use the genetic code to write two separate languages. One describes how proteins are made, and the other instructs the cell on how genes are controlled. One language is written on top of the other, which is why the second language remained hidden for so long. The genetic code uses a 64-letter alphabet called codons. The UW team...

Most researchers agree that Paleoamericans moved across the Bering Land Bridge from Asia sometime before 15,000 years ago, suggesting roots in East Asia. But just where the source populations arose has long been a mystery. Now comes a surprising twist, from the complete nuclear genome of a Siberian boy who died 24,000 years ago—the oldest complete genome of a modern human sequenced to date. His DNA shows close ties to those of today's Native Americans. Yet he apparently descended not from East Asians, but from people who had lived in Europe or...

Such is the case with a new genetic history of Europe, traced by an international team of researchers and published today in Science. By creating a seamless genetic map from 7,500 to 3,500 years ago in one geographic region, scientists discovered that the genetic diversity of modern day Europe can’t be explained by a single migration, as previously thought, but by multiple migrations coming from a range of areas in modern day...

    The majority of Ashkenazi Jews are descended from prehistoric European women, according to study published today (October 8) in Nature Communications. While the Jewish religion began in the Near East, and the Ashkenazi Jews were believed to have origins in the early indigenous tribes of this region, new evidence from mitochondrial DNA, which is passed on exclusively from mother to child, suggests that female ancestors of most modern Ashkenazi Jews converted to Judaism in the north Mediterranean around 2,000 years ago and later in west and central Europe.

    A transgender man is the first in Europe to give birth to a baby after becoming pregnant through a sperm donor. The unidentified man, who was born a woman, delivered the baby boy at home with a midwife in the poor Neukoellin district of Berlin. He insisted on a home birth because he refused to be listed as the mother on any hospital documents - a legal requirement of in Germany. The case in Germany mirrors that of Thomas Beatie in the US, pictured, who has given birth to three children and was the first man to ever give birth...

    The scientists examined the DNA of mitochondria, tiny power plants within cells that get passed down from mother to child. Scientists use mitochondrial DNA from living populations to decipher ancient movements of their ancestors. Most studies have examined only a small part of the mitochondria's circular piece of DNA. But Antonio Torroni, a geneticist at the University of Pavia in Italy, and his coauthors compiled complete mitochondrial genomes from 41 native North Americans and combined that data with information from previous studies... supports the widely accepted notion of an initial coastal migration wave. A second wave of migration probably left...

    WASHINGTON — It has been a decade since the human genome was first sequenced and the 3.2 billion rungs of our DNA ladder laid out for analysis. That achievement — mapping the fundamental biological code that defines our species and characterizes us as individuals — may have implications as important as the splitting of the atom or the discovery of the wheel. We can already envision custom-designed medicines as well as custom-designed fetuses. There are ethical questions to be asked and scientific questions to be answered. And nothing about the subject is simple. But credit “Genome: Unlocking Life’s Code,” an...

    The same protein tells beta cells in the pancreas to stop making insulin and then to self-destruct as diabetes worsens, according to a University of Alabama at Birmingham (UAB) study published online today in the journal Nature Medicine. Specifically, the research revealed that a protein called TXNIP controls the ability of beta cells to make insulin, the hormone that regulates blood-sugar levels. "We spent years confirming that TXNIP drives beta-cell death in both Type 1 and Type 2 diabetes," said Anath Shalev, M.D., director of the UAB Comprehensive Diabetes Center and senior author of the paper. "We were astounded to...

    The Book of Genesis puts Adam and Eve together in the Garden of Eden, but geneticists’ version of the duo — the ancestors to whom the Y chromosomes and mitochondrial DNA of today’s humans can be traced — were thought to have lived tens of thousands of years apart. Now, two major studies of modern humans’ Y chromosomes suggest that ‘Y-chromosome Adam’ and ‘mitochondrial Eve’ may have lived around the same time after all. When the overall population size does not change (as is likely to have happened for long periods of human history), men have, on average, just one...

    FULL TITLE: Autism breakthrough as 'genetic signature' in babies as young as a year found; blood test in the works A GENETIC "signature" of autism in babies as young as 12 months has been identified for the first time, an international conference is to be told. A simple blood test is now being developed and may be available in one to two years, Professor Eric Courchesne will tell the Asia Pacific Autism conference in Adelaide today. "This discovery really changes the landscape of our understanding of causes and effective treatments," says the director of the Autism Centre of Excellence at...
