Old data can be mined to find new genetic associations and gene interactions The power of genome-wide association studies (GWAS) to detect genetic influences on human disease can be substantially increased using a statistical testing framework reported in the May issue of the journal GENETICS. Despite the proliferation of GWAS, the associations found so far have largely failed to account for the known effects of genes on complex disease — the problem of "missing heritability."...

The influence of genetic factors on differences between children's Body Mass Index (BMI) increases from 43% at age 4 to 82% at age 10, reports a new study by researchers at UCL and King's College London. The research, published in the journal Obesity, combined twin and genomic analyses in 2556 pairs of twins from the Twins Early Development Study. Data were collected in England and Wales in 1999 and 2005 when the twins were 4 and 10 years old respectively. The study was supported by the UK...

Brain and song structure in zebra finches are strongly influenced by the environment The song of songbirds is a learned, complex behavior and subject to strong selective forces. However, it is difficult to tease apart the influence of the genetic background and the environment on the expression of individual variation in song. Scientists from the Max Planck Institute for Ornithology in Seewiesen in collaboration with international researchers now compared song and brain structure of...

The fact that taller people also tend to be slightly smarter is due in roughly equal parts to two phenomena—the same genes affect both traits and taller people are more likely than average to mate with smarter people and vice versa—according to a study led by the University of Colorado Boulder. The study did not find that environmental factors contributed to the connection between being taller and being smarter, both traits that people tend to find attractive. The modest correlation...

Model including dozens of mutations helps clarify genetic factors involved in Crohn's disease A statistical model accounting for dozens of different genes in combination—and the interactions between them—is an important step forward in understanding the genetic factors affecting the risk of Crohn's disease (CD), reports a study in Inflammatory Bowel Diseases, official journal of the Crohn's & Colitis Foundation of America (CCFA). The journal is published by Lippincott Williams...

New bio-imaging technology peers into the heart of embryo development Scientists using a pioneering bio-imaging system to record simultaneously the development of hundreds of aquatic embryos have discovered significant parent-offspring similarities in the timing and sequence of that development. Researchers at Plymouth University have found the timing of key developmental milestones – such as the first beating of the heart, formation of the eyes and movement – differs markedly...

-An early age at first drink (AFD) is associated with a greater risk for subsequent alcohol use disorders. -A new study looks at the influences of genetics versus the environment on AFD and problem drinking among African American (AA) and European American (EA) women. -Findings indicate that environmental factors play a larger role in the development of alcohol-related problems in EA than AA women. An early age at first drink (AFD) is associated with a greater risk for subsequent alcohol...

Alan McStravick for redOrbit.com - Your Universe Online So You Think You Can Dance. Cosmo. America´s Next Top Model. Maxim. Barbie Dolls. These are but a few examples of what many social scientists have decried as being at the root of a culture obsessed with an elusive and often impossible ideal of thinness. This study, published in the International Journal of Eating Disorders has found that genetics may make some women more vulnerable to the pressures associated with being thin....

(Ivanhoe Newswire) "“ The largest known study of twins with autism spectrum disorder (ASD) suggests that environmental influences and maternal infections during pregnancy may greatly increase risk for ASD. Environmental influences include parental age, low birth weight and multiple births. The study suggested that both genetic and shared environmental factors significantly increase risk for ASD: an estimated 38 percent of risk being associated with genetic heritability and 58 percent...

Non-inherited genetic factors also in the mix -- NIH-funded science The largest and most rigorous twin study of its kind to date has found that shared environment influences susceptibility to autism more than previously thought. The study, supported by the National Institutes of Health, found that shared environmental factors "“ experiences and exposures common to both twin individuals "“ accounted for 55 percent of strict autism and 58 percent of more broadly defined autism...
