The genetic domino effect that his team uncovered may have less to do with extending life, he says, then with making it possible to survive caloric restriction at all.
In cases where the side-effect has a genetic root, failures could be averted by excluding potential victims from trials and, of course, from treatments after the drug is approved.
Since such organisms (simple yeasts or bacteria) would carry a brand-new genetic code, they would in effect be new life forms.
Third, researchers have focused on so-called gene-environment interactions, reasoning that some exposures that have relatively weak associations with breast cancer in the general population may have a much stronger effect in subgroups with a specific genetic make-up.

Dr Moffitt's team (the actual work was led by her colleague, Avshalom Caspi) looked at the effect on intelligence of breastfeeding, but in a genetic context.
Groups that include Greenpeace and the Union of Concerned Scientists fret that Africa is being manipulated by multinational corporations, in effect serving as one big--potentially dangerous--genetic experiment.

Iceland, in effect, is a huge extended family that can be used to investigate genetic inheritance.
But the Cystic Fibrosis Trust said the medicine was "transformational", had a "dramatic effect" and that experts say "no other medicine addresses the basic genetic defect in cystic fibrosis".

One interesting point about this observation is that it requires both a genetic input (the 7R variant) and an environmental one (the network of friends) to take effect.
