Diabetes, Diet & Fitness, Heart, News & Analysis by Spectator Health reporter 10th October 2018 Share This Twitter Facebook Google+ Email Researchers at at Harvard Medical School in the US have discovered a gene mutation that slows the metabolism of sugar in the gut, giving people who have the mutation a distinct advantage over those who do not. Those with the mutation have a lower risk of diabetes, obesity, heart failure, and even death. The researchers say their finding could provide the basis for drug therapies that could mimic the workings of this gene mutation, offering a potential benefit for the millions of people who suffer with diabetes, heart disease, and obesity. The study, which has been published in the Journal of the American College of Cardiology, shows that people who have the natural gene mutation have an advantage when it comes to diet. Those who eat a high-carbohydrate diet and have this mutation will absorb less glucose than those … [Read more...] about Newly discovered gene mutation could be used to treat diabetes and heart disease

Photo: Internet SYDNEY, 26 June (BelTA - Xinhua) - Scientists have identified hundreds of new genes associated with intelligence, a joint research project from the University of Queensland's Brain Institute and its partners in the Netherlands revealed on Tuesday.As well as the 939 new "smart genes," the authors said in another study that they had identified over 500 genes associated with neuroticism, an important risk factor for depression and schizophrenia."These results are a major step forward in understanding the neurobiology of cognitive function as well as genetically related neurological and psychiatric disorders," the study said.More than 250,000 individuals were tested for their genetic data and measurements of intelligence, while the study into neuroticism took data from almost half a million respondents.Together these studies provide new insights into the neurobiology and genetics of cognition.According to researchers, the findings suggest that our brains have … [Read more...] about Hundreds of new “smart genes” discovered by brain scientists
Leprosy may have originated in Europe rather than Asia, according to the largest study to date on ancestral strains of the disease. The study has revealed that more leprosy strains than expected were present in medieval Europe, prompting scientists to reconsider the origins and age of the devastating disease. “For centuries there has been a question mark over where leprosy originated; most assumptions believing it started in China and the Far East,” said Helen Donoghue, a co-author of the latest work and scientist at University College London. “This latest research shows all the strains of the leprosy bacterium, were in fact present in medieval Europe, which strongly suggests leprosy originated much closer to home, possibly in the far south east of Europe, or western Asia.” Leprosy is one of the oldest recorded and most stigmatised diseases in human history. It was prevalent in Europe until the 16th century and is still endemic in many countries, mainly in … [Read more...] about New study suggests leprosy came from Europe
"Scientists Find Surprising Link Between Birth Month And Disease Risk," the Huffington Post reports. Using data mining techniques on 1.7 million electronic medical records, US researchers found an association between birth month and certain chronic diseases, as well as less serious conditions such as insect bites.Fifty-five diseases were found to be associated with birth month – 19 were previously reported in the literature, 20 were for conditions with close relationships to those previously reported, and 16 were new associations. The newly found associations were a mixed bag, ranging from various cardiovascular diseases (such as high blood pressure and heart failure) and prostate cancer, to incidents such as bruising and insect bites.The researchers speculate, based on the findings of other studies, why seasonal factors may contribute to specific disease risk, suggesting it could be the result of exposure to antigens such as pollen, varying vitamin D levels, and possibly … [Read more...] about Does your birthday affect your disease risk?
Scientists have pieced together the skull of a toothed bird that they say illustrates the pivotal period in history in which dinosaurs transitioned into modern-day avians. Known as Ichthyornis dispar, the seagull-like creature lived in North America about 86 million years ago and was first discovered in the 1870s. The species, which prospered along the warm, shallow sea which once divided the continent, drew the attention of 19th century naturalists including Charles Darwin, who said its toothy jaw offered important insights into evolution. Read more Revealed: The secret of how birds evolved from dinosaurs However, for more than a century the only known specimens of the bird’s skull were flattened or fragmented fossils, limiting researchers’ knowledge of the species. Now, for the first time, a team led by scientists at Bath and Yale universities have produced a clear 3D picture of the bird’s head, using a complete skull discovered in 2014 and two … [Read more...] about First birds had full set of teeth, prehistoric fossils show
