The Basques are culturally and geno-graphically unique, thought to be a mesolithic remnant settling in the northern area of Spain before the LCM (Last Glacial Maximum).

M ost people can get their heads wrapped around the idea that genetic variation can occur by virtue of the presence (or lack) of a particular gene. And no doubt some of you understand the basis of the simple mutations that can influence gene function, such as point deletions (which would make you blood group […]

Many bacteria are capable of altering their genetic expression based upon an assessment of their environmental conditions and a novel approach to controlling bacterial infection may involve interfering with the ability of one bacteria to communicate with another. Interestingly, their modus operandi also makes good New Age music.

The beneficial effects of caloric restriction (or therapies that mimic caloric restriction) appear to exert transgenerational effects -at least in rotifers. A new study appears to implicate the enzyme catalase with the longevity benefits of caloric restriction.

A new study on the role of mucosal immunity and host genetics in defining intestinal commensal bacteria indicates that basic elements of gut immunity, such as antibody secretory IgA (sIgA) exert profound effects on the composition of the bacterial flora that inhabit the gut.

There is emerging evidence that persistent organic pollutants (POPs) can increase the risk of various chronic diseases. As POPs mainly bioaccumulate in adipose tissue, weight change can affect serum concentrations of POPs.
