Ebola, Marburg viruses edit genetic material during infectionFiloviruses like Ebola "edit" genetic material as they invade their hosts, according to a study published this week in mBio®, the online open-access journal of the American Society for Microbiology. The work, by researchers at the Icahn School of Medicine at Mount Sinai, the Galveston National Laboratory, and the J. Craig Venter Institute, could lead to a better understanding of these viruses, paving the way for new treatments down the road. Using a laboratory technique called deep sequencing, investigators set out to investigate filovirus replication and transcription, processes involved in the virus...

The modern European gene pool was formed when three ancient populations mixed within the last 7,000 years, Nature journal reports. Blue-eyed, swarthy hunters mingled with brown-eyed, pale skinned farmers as the latter swept into Europe from the Near East. But another, mysterious population with Siberian affinities also contributed to the genetic landscape of the continent. The findings are based on analysis of genomes from nine ancient Europeans. Agriculture originated in the Near East - in modern Syria, Iraq and Israel - before expanding into Europe around 7,500 years ago. It really does look like the indigenous West European hunter gatherers...

Now a new study suggests that a simple blood test could soon allow doctors to diagnose clinical depression as easily as they check cholesterol. Researchers at Northwestern University have developed the first blood test that analyzes levels of nine blood biomarkers associated with adult clinical depression. The results of their study were published Tuesday in the journal Translational Psychiatry. The test looks at levels of nine RNA blood markers, which appear to be different among patients with diagnosed clinical depression versus those who do not have depression. RNA are the molecules that help to process DNA genetic code and carry...

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. This morning, I read...

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...

I will always remember that look on her face. I knew it was not good news. We were expecting our third child. My wife, Samantha, went to our doctor for a routine appointment. Our first two pregnancies went perfectly. Not this time. After analyzing the blood Samantha provided, the doctor determined that there was an increased risk for our child to have spina bifida…. After we arrived at the specialist for additional tests… we met with a genetic specialist who did everything in her power to use words I had never heard of before. Illnesses, deformities and abnormalities: she laid...

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...

Nicholas Wade, a British-born science reporter and editor for more than 30 years with The New York Times, is no longer with the newspaper — just days after the release of his latest book, in which he depicts blacks with roots in sub-Saharan Africa as genetically less adapted to modern life than whites and Asians. Was The New York Times uncomfortable with Wade’s science or his conclusions? It’s unclear. Neither Wade nor his former employer returned requests for comment. Wade’s last Times article appeared April 24. His Penguin Press book “A Troublesome Inheritance: Genes, Race and Human History” arrived in...

Nicholas Wade, a leading science writer whose specialty is human evolution, likes to ask interesting questions. Here are some examples: Why has the West been the most exploratory and innovative civilization in the world for the past 500 years? Why are Jews of European descent so massively overrepresented among the top achievers in the arts and sciences? Why is the Chinese diaspora successful all around the world? Why is it so difficult to modernize tribal societies? Why has economic development been so slow in Africa? Contemporary thinkers have offered lots of provocative answers for such questions. It’s all about geography....

‘This book is an attempt to understand the world as it is, not as it ought to be.’ So writes Nicholas Wade, the British-born science editor of The New York Times, in his new book A Troublesome Inheritance. For some time the post-War view of human nature as being largely culturally-formed has been under attack just as surely as the biblical explanation of mankind’s creation began to face pressure in the early 19th century. What Steven Pinker called the blank slate view of our species, whereby humans are products of social conditions and therefore possible to mould and to perfect...

After nearly 30 years studying how plants use their genes to defend against viruses, Vicki Vance, a professor at the University of South Carolina, doesn’t see genetically modifying plants as a malevolent or arrogantly God-like endeavor. “There’s DNA in the world and it gets passed from one organism to another and it’s the natural thing. 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....

A new bill to mandate labeling of genetically altered food gets history and science all wrong.Last week, in a victory for California’s radical anti-technology minority, S.B. 131 passed the state’s senate Health Committee by a vote of five to two. This misguided piece of legislation, introduced by state senator Noreen Evans, would require that “any food, except as provided, offered for retail sale in the state be considered misbranded if it is entirely or partially genetically engineered, as defined, and that fact is not disclosed in a specified manner.” In other words, it would require a label to inform consumers...
