...This is a step towards identifying specific adaptations that have risen as humans expanded and faced new environments,” said Shari R. Grossman ’08, the lead author of the paper...
...loudest and most persistent critics of the administration of Rajapaksa. Although he considered Rajapaksa an old friend, he criticized him over the conduct of the war and lack of safety for the civilians trapped by the fighting. A posthumous editorial that appeared in the Sunday Leader, the paper that Wickrematunge founded, immediately after his murder addressed Rajapaksa directly: "In the wake of my death, I know you will make all the usual sanctimonious noises and call upon the police to hold a swift and thorough inquiry. But like all the inquiries you have ordered in the past, nothing will come...
...would mean that genes themselves wouldn't have had enough years to change. But, Pembrey reasoned, maybe the epigenetic marks atop DNA would have had time to change. Pembrey wasn't sure how you would test such a grand theory, and he put the idea aside after the Acta paper appeared. But in May 2000, out of the blue, he received an e-mail from Bygren - whom he did not know - about the Overkalix life-expectancy data. The two struck up a friendship and began discussing how to construct a new experiment that would clarify the Overkalix mystery...
...Pembrey, Bygren and 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...
...ALSPAC and Overkalix results in terms of the exposure-sensitive periods and sex specificity supports the hypothesis that there is a general mechanism for transmitting information about the ancestral environment down the male line," Pembrey, Bygren, Golding and their colleagues concluded in the European Journal of Human Genetics paper. In other words, you can change your epigenetics even when you make a dumb decision at 10 years old. If you start smoking then, you may have made not only a medical mistake but a catastrophic genetic mistake...
