Radio Review: Frontiers - Epigenetics
This Frontiers programme challenged three genetic dogmas. The presenter quoted a recent Observer headline on epigenetics: 'Why everything we were told about evolution was wrong!'...

Obesity in male rats increases the risk of their daughters developing diabetes in later life, a study by scientists at the University of New South Wales, Sydney, has found. The researchers believe epigenetic inheritance - changes in chemical markers on genes that affect their function - may be responsible...
Scientists from the UK and China are collaborating to study epigenetic signatures that mark the differences between 5,000 twins. Those affected by diabetics and osteoporosis are just some of the people who could be set to benefit from the £20 million 'Epitwin' project....
Chemical modifications to genes over a person's lifetime may influence their weight without changing their inherited DNA sequence, a new study has found. This is the first time long-standing chemical alterations to genes have been linked to body weight and obesity...
Stem cells created from a patients' own tissue are subtly different from those derived from embryos in ways that may affect their therapeutic potential, two independent research groups have found. Both studies found induced pluripotent stem cells (iPS) retain an 'epigenetic memory' of their tissue of origin...

US scientists have shown for the first time how a virus, a toxin and a genetic mutation interact to cause Crohn's disease. The study, in mice, may help explain why many people with disease risk genes don't develop the condition...
Rats fed on high-fat diets increased the chances of their daughters and granddaughters developing breast cancer, a US study has found...

The models emerging from behavioural biology are increasingly sophisticated. They do not undermine the quest for candidate genes, but rather augment our understanding of why those genes might persist in populations and be differentially expressed across circumstances....
The announcement that scientists at the University of Newcastle have developed a new procedure that could eventually help women with dysfunctional mitochondria (the energy source of the cell), made headline news across the world...
A new study into autism has found a link between the disorder in children and their grandparents' age. The research, published in PLoS ONE last week, is the first of its kind to look at grandparent's as opposed to parents' ages...
