This is almost like harmful secondhand cigarette smoke. Researchers from Harvard Medical School's Department of Global Health and Social Medicine examined the link between media consumption and eating disorders among adolescent girls in Fiji. What they found was surprising. The study's subjects did not even need to have a television at home to see raised risk levels of eating disorder symptoms. In fact, by far the biggest factor for eating disorders was how many of a subject's friends and schoolmates had access to TV. By contrast, researchers found that direct forms...

The theory outlines that genes from the father’s sperm are in an evolutionary tug-of-war with genes from the mother’s egg. Whichever becomes dominant tips brain development that direction. An excerpt from the NY Times - A strong bias toward the father pushes a developing brain along the autistic spectrum, toward a fascination with objects, patterns, mechanical systems, at the expense of social development. A bias toward the mother moves the growing brain along what the researchers call the psychotic spectrum, toward hypersensitivity to mood, their own and others’. This, according to the theory, increases a child’s risk of developin...

This was the implications of a new study on children born during the famine of World War II. Scientists studied the DNA of children who were born to women starved during the 1944 Hunger Winter in the Netherlands. They analyzed a gene called insulin-like growth factor 2 or IGF2, an important growth hormone. Methyl groups that attach to IGF2 very early in fetal development determine how much of the growth hormone is made later, and protect the DNA from damage. The scientists found that those children (now in their 60s)  who were exposed to famine in the first trimester of pregnancy had lesser methyl groups in the IGF2 gene than their siblings of the same sex. Loss of methylation in IGF2 has previously b...

We used comparative analysis to investigate the origin of genomic imprinting in mammals. PEG10 (paternally expressed 10) is a retrotransposon-derived imprinted gene that has an essential role for the formation of the placenta of the mouse. Here, we show that an orthologue of PEG10 exists in another therian mammal, the marsupial tammar wallaby (Macropus eugenii), but not in a prototherian mammal, the egg-laying platypu...

The Genie revealed unto me that I shall search the OMIM database with the term “instance“. Thus instructed, let’s venture into the vast expanse of the human genome… Again, as with the previous search term “organizer”, the Genie has lead me into familiar territory. The word “instance” brings up not a gene, but rather a syndrome - PRADER-WILLI SYNDROME (PWS). The reason PWS is familiar to me is because Rachel Wevrick in the Department of Medical Genetics at the University of Alberta has centred her lab around genes associated with this disease.

According to classical evolutionary theory, phenotypic variation originates from random mutations that are independent of selective pressure. However, recent findings suggest that organisms have evolved mechanisms to influence the timing or genomic location of heritable variability. Hypervariable contingency loci and epigenetic switches increase the variability of specific phenotypes; error-prone DNA replicases produce bursts of variability in times of stress. Interestingly, these mechanisms seem to tune the variability of a given phenotype to ma...
