The public perception of the life sciences--including biotechnology--has in recent years drifted far from the reality. Bringing perception and reality closer together requires an open dialogue between science and society based upon a well thought-out educational policy and a better mutual understanding between scientists and media professionals.

Previous Y chromosome studies have shown that the Cohanim, a paternally inherited Jewish priestly caste, predominantly share a recent common ancestry irrespective of the geographically defined post-Diaspora community to which they belong, a finding consistent with common Jewish origins in the Near East. In contrast, the Levites, another paternally inherited Jewish caste, display evidence for multiple recent origins, with Ashkenazi Levites having a high frequency of a distinctive, non-Near Eastern haplogroup. Here, we show that the Ashkenazi Levite microsatellite haplotypes within this haplogroup are extremely tightly clustered, with an inferred common ancestor within the past 2,000 years. Comparisons with other Jewish and non-Jewish groups suggest that a founding event, probably involving one or very few European men occurring at a time close to the initial formation and settlement of the Ashkenazi community, is the most likely explanation for the presence of this distinctive haplogroup found today in >50% of Ashkenazi Levites.

It might be an exaggeration to claim that UK agriculture is in a state of crisis, but it is certainly a time for decisions. Uncertainties abound: the implications of growing free trade; a steady reduction in subsidies; the ongoing drift of people to towns and what some regard as the stranglehold of retailers both on food prices and on what the farmer gets. To all of this has to be added the backwash of bovine spongiform encephalopathy (BSE) and foot-and-mouth disease (FMD), and the advent of new technologies, especially those based on modern genetics.
