A Zoll (Customs) sign is seen on a wooden bridge over the Rhein river between Switzerland and Germany in Rheinau May 1, 2014. Switzerland will vote on November 30 on an initiative from the group Ecopop which proposes a cap on the number of immigrants. The group says it is motivated by concerns about a lack of living space exerting too much pressure on the land and natural resources, rather than by opposition to foreigners. It proposes limiting immigration to just 0.2 percent of the resident population, equivalent to 16,000 people per year. This would represent a cut of more than 75 percent in annual net immigration from current levels. In Switzerland's system of direct democracy, any voter can trigger a referendum by collecting 100,000 signatures within 18 months. Picture taken May 1, 2014.

Dagestani born tycoon Suleiman Kerimov watches a soccer match between Anzhi and CSKA in Makhachkala December 2, 2012. Kerimov built his multi-billion-dollar fortune with an appetite for risk, debt and excellent political connections. Yet there are signs that the secretive mining tycoon has used up his credit with President Vladimir Putin, who exerts a tight grip over the strategic natural resources that fuel Russia's $2 trillion economy. The 47-year-old from Dagestan has found himself in a tight spot after his company Uralkali pulled out of a potash cartel with Belarus in July, upsetting the market and infuriating a close - if difficult - ex-Soviet ally.

Russian and U.S. oceanographers studying the impact of global warming on the Bering Strait in late August enjoyed seas on some days that were so calm their ship made the only ripples. But the serenity of the seascape belied increasingly turbulent waters for scientific research as countries exert sovereignty over Arctic territory and Big Oil boosts exploration efforts.
