...teaspoon pretty much covers the entire surface area of the spoon and thus looks like a lot to us. But the same 5 ml on a large spoon somehow appears to be less, and as a result we add more. (See how to prevent illness at any age...
...Golding - now all working together - used the data to produce a more groundbreaking paper, the most compelling epigenetic study yet written. Published in 2006 in the European Journal of Human Genetics, it noted that of the 14,024 fathers in the study, 166 said they had started smoking before age 11 - just as their bodies were preparing to enter puberty. Boys are genetically isolated before puberty because they cannot form sperm. (Girls, by contrast, have their eggs from birth.) That makes the period around puberty fertile ground for epigenetic changes: If the environment is going to imprint epigenetic marks...
When Pembrey, Bygren and Golding looked at the sons of those 166 early smokers, it turned out that the boys had significantly higher body mass indexes than other boys by age 9. That means the sons of men who smoke in prepuberty will be at higher risk for obesity and other health problems well into adulthood. It's very likely these boys will also have shorter life spans, just as the children of the Overkalix overeaters did. "The coherence between the ALSPAC and Overkalix results in terms of the exposure-sensitive periods and sex specificity supports the hypothesis that there...
...code that we and our children and their children had to live by. Now we can imagine a world in which we can tinker with DNA, bend it to our will. It will take geneticists and ethicists many years to work out all the implications, but be assured: the age of epigenetics has arrived...
...Although the 139 were predominantly young men, with 90 being under the age of 30, they hailed from diverse ethnicities: 32 were Arabs, 24 African-Americans, 24 South Asians, 20 Somalis and 20 whites. The authors say there is no "single profile or a common warning sign that signifies a homegrown terrorist...
