Police in Brazil say this is the largest operation they've ever launched in the southern state of Rio Grande do Sul. In a series of raids in the city of Sao Borja, they seized weapons, money, vehicles and quantities of cocaine and marijuana. The police chief heading the operation said up to 13 different drug gangs had been identified in the city, including one with 40 members. Sao Borja is on the main transit route for drugs and contraband between Brazil and the neighbouring countries - Argentina, Uruguay and Paraguay.

巴西警方称这次在南部Rio Grande do Sul州展开的缉毒行动是有史以来规模最大的一次。在一系列对Sao Borja市进行的突袭中，他们缴获了武器，钱财，车辆，及大量可卡因和大麻。领导此次行动的警长称，目前警方已在该市确定了13个贩毒组织，其中一个组织有40名毒犯子。Sao Borja市位于巴西和周边国家，阿根延，乌拉圭，和巴拉圭进行贩毒和走私的主要通道。

An Italian physicist who last year challenged one of the foundations of modern physics has resigned. Antonio Ereditato and his team stunned the scientific world last September with claims they'd observed subatomic particles called neutrinos travelling faster than the speed of light. The result would have disproved Einstein's special theory of relativity, but later experiments called the results into question.
