A low-carb diet may help IBS as much as tricky elimination diets, and more than drugs The standard advice for symptoms of IBS is either medication or a tough-to-follow diet called low FODMAP. A new study finds both that diet and the much simpler low-carb diet brought more relief than drugs.

World’s biggest set of human genome sequences opens to scientists The whole genomes of 500,000 people in the UK Biobank will help researchers to probe our genetic code for links to disease.

Mental Illness, Especially Later in Life, Can Increase the Risk of Dementia Research is revealing an inextricable link between mental disorders and neurological disorders.

Tai chi helps boost memory, study finds. One type seems most beneficial Research shows that a daily dose of tai chi, the slow-moving meditative, martial art can boost our body and brain. A new study finds adding word games to tai chi doubles the increase in memory.

Your cells don’t have the genome you were born with. Project aims to chart impact of new mutations Major NIH effort will probe the health effects of DNA changes acquired by only some tissues and organs

Genetic tests are nothing new. Most of these technologies rely on measuring light absorption or emission from probe molecules tailored to latch onto the target gene. But to produce a signal large enough to detect, most of the technologies rely on amplifying techniques such as polymerase chain reaction to produce many copies of the target before trying to detect them, adding to the cost and time of the tests.

Dementia risk linked to blood-protein imbalance in middle age Abnormal levels of certain proteins — many of which have roles outside the brain — could be an early hallmark of Alzheimer’s disease or similar conditions.

Do you take part in genetic studies? That might be in your genes Findings could help researchers to better understand ‘participation bias’ in studies that link genomics with health, behaviour and other traits.

Even though 99.6% of our genome sequences are the same, there are slight differences in each person’s genome. These differences are called genomic variants. Out of the 6 billion letters in our genomes, each of us has around 4 to 5 million genomic variants! These variants could either be unique to us or show up in other people’s genomes as well.

Scientists Unveil a More Diverse Human Genome The “pangenome,” which collated genetic sequences from 47 people of diverse ethnic backgrounds, could greatly expand the reach of personalized medicine.

Scientists have long known that just a tiny fraction of our DNA contains so-called protein-coding genes, which make crucial proteins like digestive enzymes in our stomach, collagen in our skin and hemoglobin in our blood. All of our 20,000 protein-coding genes make up just 1.5 percent of our genome. The other 98.5 percent is far more mysterious.
