Amino acids link gut microbiome to obesity

Researchers at Lund University in Sweden have discovered a new link between gut bacteria and obesity. They found that certain amino acids in our blood can be connected to both obesity and the composition of the gut microbiome. Increasing number of research studies indicate that our gut microbiome does play an important role in our…
Researchers create better wearable medical sensors based on graphene nano-flakes

Team of researchers at University of British Columbia Okanagan campus have developed a practical way to monitor and interpret human motion.The sensor is made by infusing graphene nano-flakes (GNF) into a rubber-like adhesive pad. Najjaran says they then tested the durability of the tiny sensor by stretching it to see if it can maintain accuracy…
Calorie restricted diet promotes intestinal regeneration after injury

Dramatic calorie restriction have long been known to boost healthy lifespan and reduce the risk of heart attack, diabetes and other age-related conditions. In animal studies it is shown to extend life span in most animal species examined. Further research has shown that animals fed restricted-calorie diets are also better able to regenerate numerous tissues…
People with depression found to have low arginine levels

Researchers from the University of Eastern Finland have shown that people suffering from major depressive disorder have reduced arginine levels. One of the role of arginine in body is to produce nitric oxide, which in turn have role in vascular regulation and is a nervous system and immune defence mediator. The global arginine bioavailability ratio…
Research suggests that heating coils contribute toxic metals in e-cigarette vapors

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. The study is published online in Environmental Health Perspectives. In the study, the scientists examined e-cigarette devices owned by…
Roadmap to develop strategies for radioresistance to facilitate space exploration published

An international team of researchers from various academic institutions and NASA Ames Research Center have published a roadmap toward enhancing human radioresistance in the peer-reviewed journal Oncotarget. This is important as our interest in space exploration and colonization is increasing and therefore, research into methods of enhancing radioresistance to protect against the various forms of…
Artificial intelligence algorithm to predict and prevent spread of infectious diseases

Team of researchers from USC Viterbi School of Engineering has created an algorithm that can help policymakers reduce the overall spread of disease. The algorithm is optimized to make the most of limited resources, such as advertising budgets, thus helping cash strapped public health agencies. To create the artificial intellegence algorithm, the researchers used behavioral,…
Computational study finds new genetic targets for autism

Researchers at the University of Missouri created a new computational method that has connected several target genes to autism. Recent discoveries could lead to screening tools for young children and could help doctors determine correct interventions when diagnosing autism. Unlocking the genetic causes of autism requires data-intensive computations. In 2014, the National Science Foundation (NSF)…
New research shows relationship between activity levels and mortality in elderly

Doing just a few minutes at a time of any level of physical activity, is linked to a lower risk of death in older men according to a new study published online in the British Journal of Sports Medicine. Providing the recommended 150 minute weekly tally of moderate physical activity is reached, total volume, rather…
Role of calcium in Parkinson’s disease

The international team, led by the University of Cambridge found that excess levels of calcium in brain cells may lead to the formation of toxic clusters that are the hallmark of Parkinson’s disease. Their research found that calcium can mediate the interaction between small membranous structures inside nerve endings, which are important for neuronal signalling…
