Background levels of K-40 on non-cultivated soils in Quebec and in several northern sites elsewhere in Canada are presented. The activity of K-40 was measured at 34 sites. The specific activity levels ranged from 59 to 801 Bq kg–1 with an overall mean of 396±195 Bq kg–1. This activity generates the annual dose equivalent of 0.1 mSv. In most cases (24 out of 34), the concentration of K-40 slightly decreases with the increasing depth. The activities were found to be approximately normally distributed. There is a regional difference between the concentrations of K-40 in soils in northern and southern Quebec.
The distribution of Mexican health science publications according to the states of origin, institutions, main cities has been measured in four main health science bibliographic databases. The results showed that Mexican health sciences research activities are highly skewed.
We applied population memetic models to the analysis of cultural variation among 11 European reed bunting (Emberiza schoeniclus) populations belonging to two subspecies groups differing in bill morphology. We tested whether patterns of meme diversity within and among populations and between the two subspecies groups correspond to patterns of variation in bill morphology. Within-population meme diversity was high and the degree of memetic divergence within groups was significant and higher among southern thick billed populations than among northern thin billed populations. There was, however, no significant memetic difference between the two subspecies groups. Tests of correlation between all groups indicated that memetic variation is associated with geographical distance and not with morphological variation. The results suggest a demographic structure of reed bunting populations similar to that of island populations of other bird species. The lack of memetic differences between them indicates that populations are not culturally isolated, despite the morphological, ecological and genetic differences. We discuss possible evolutionary explanations of the patterns of variation found.

In order to know the distribution of plutonium derived from the Nagasaki atomic bomb, soil samples were measured to determine
the 240Pu/239Pu isotope ratio of and concentrations of 239+240Pu and 137Cs. The 239+240Pu concentrations in soils, except for Nishiyama area, were close to the average concentration of soil collected in Japan.
In soils collected at the Nishiyama area and at the eastern area of Nagasaki Prefecture and at part of northern area in Kumamoto
Prefecture, the 240Pu/239Pu ratios were lower than the global fallout values. This suggests that plutonium from the atomic bomb was deposited in the
eastern area from the hypocenter reaching up to 100 km eastwards.

Cancer research outputs in India have expanded greatly in recent years, with some concomitant increase in their citation scores. Part of the increase in output is attributable to greater coverage in the Web of Science of Indian journals, which are more clinical than international ones, and much less often cited. Other measures of esteem have also increased, such as the percentage of reviews and the immediacy with which Indian cancer articles are cited. Most of the output came from just nine of the 35 Indian states and Union Territories, led by New Delhi and Maharashtra. The distribution of the amount of research by cancer site correlates moderately positively with the relative disease burden, with mouth (head and neck) cancer (often caused by the chewing of tobacco or areca, betel or paan) causing the highest number of deaths and also being well researched. We also analysed the articles by type of research, with articles in genetics and chemotherapy being the most numerous. For articles published in 2009–2010, data were available on the funding acknowledgements, and we found, as expected, that articles in clinical subjects were less often supported by external funding than ones in basic research. The major source of support was the Government of India, with relatively small contributions from charities and industry, unlike the situation in the UK and other western European countries.
