Such lapses in memory, according to this new research, could be blamed, at least in part, on rising blood glucose levels as we age. The findings suggest that exercising to improve blood sugar levels could be a way for some people to stave off the normal cognitive decline that comes with age.

Language in humans has evolved culturally rather than genetically, according to a study by UCL (University College London) and US researchers. By modelling the ways in which genes for language might have evolved alongside language itself, the study showed that genetic adaptation to language would be highly unlikely, as cultural conventions change much more rapidly than genes. Thus, the biological machinery upon which human language is built appears to predate the emergence of language.

Hmm...so no innateness hypothesis?
No, wait, this is referring to how we don't have "language genes" whereby I might have "Mandarin language genes" and you "French language genes". Does this also mean that a child of purely Chinese descent, if born in Turkey and brought up in a Turkish environment, will not (on the basis of race) be disadvantaged in learning Turkish [SOV] and not advantaged in learning Chinese [SVO]? This fits with the Crain-Lilo reading regarding immigrant children.
