Scientists don't debate the old nature vs. nurture question much these days. The consensus is that there is no winner: Both your genes and your environment shape your development and your health. What's still up in the air is how they combine to put you at risk for diseases or social problems. And that matters for people trying to solve them.
Now it appears that, even for a single disease or condition, the balance between nature and nurture isn't fixed place to place. That's what researchers at Kings College London, writing this week in the journal Molecular Psychiatry, are showing with maps that identify hotspots in the U.K. where either genetic or environmental factors dominate.
