While CFCs had a relatively narrow range of uses - and chemical companies like DuPont were able to come up with replacements quickly - N2O is all around us, tied intimately to our industrial way of life. The millions of tons of soil fertilizer used in U.S. agriculture alone add N2O into the atmosphere, as do livestock manure, sewage treatment and automobiles. And it's not just our doing: two-thirds of global N2O emissions come from...

The PETN explosives matched those used in the July 29 ETA bombing of a police barracks in Burgos in northern Spain that injured around 40 people. Investigators say they believe materials in the caches can also be traced to the ETA car bomb that exploded on July 30 on the tourist-packed island of Majorca, killing two Spanish police officers...
...Perhaps, but as Interior Minister Hortefeux noted on Wednesday, each time authorities deal a blow to ETA they also uncover further proof that whatever is left of the organization is still busy preparing more of the attacks that have killed around 800 people over the years.
