Is brain size linked to two common gene variants?
...rocephaly, a disease causing smaller head size and mental
retardation. Specific normal variants of the MCPH1 and ASPM genes have attracted scientific attention, because they are now widespread in some human populations -- despite evidence that these variants first arose only 5,000 to 37,000 years ago. This ...

...other areas, such as attention, aggression, or any mental
disorders, have gotten less attention. Exposure to inorganic lead, like that found in paint, remains an important public health problem. And those of us who grew up before the late 1970s still carry high lead levels in our bodies. We need more studie...
