Under attack: policemen stand guard outside the Monterrey Institute of Technology and Higher Education after a letter bomb exploded there in August 2011.

The shoe-box-sized package was addressed to Armando Herrera Corral. It stated that he was the recipient of an award and it was covered in official-looking stamps. Herrera, a computer scientist at the Monterrey Institute of Technology and Higher Education in Mexico City, shook the box a number of times, and something solid jiggled inside. What could it be? He was excited and a little nervous so much so, that he walked down the hall to the office of a colleague, robotics researcher Alejandro Aceves Lpez, and asked Aceves to open it for him.
Aceves sat down at his desk to tear the box open. So when the 20-centimetre-long pipe bomb inside exploded, on 8 August 2011, Aceves took the full force in his chest. Metal pierced one of his lungs. He was in intensive care. He was really bad, says Herrera's brother Gerardo, a theoretical physicist at the nearby Centre for Research and Advanced Studies of the National Polytechnic Institute (Cinvestav). Armando Herrera Corral, who was standing nearby when the bomb went off, escaped with a burst eardrum and burns to his legs.
The next day, an eco-anarchist group calling itself Individuals Tending Towards Savagery (ITS) claimed responsibility for the bombing in a 5,500-word diatribe against nanotechnology that it published online. Police found a charred copy of a similar text in the detritus of the explosion. The bombers said that Herrera had been targeted for his role as director of the technology-transfer centre at the Monterrey Institute of Technology and Higher Education (commonly known as Monterrey Tec), one of the major universities that has staked everything on the development of nanotechnology. The text talked of the potential for the field to cause environmental nanocontamination, and concluded that technology and civilization as a whole should be held responsible for any environmental catastrophe. Chillingly, the bombers listed another five researchers at Monterrey Tec as presumptive targets, as well as a further six universities.

The incident had precedent. The ITS had already claimed responsibility for bomb attacks in April and May 2011, both targeting Carlos Alberto Camacho Olgun, head of engineering and nanotechnology at the Polytechnic University of the Valley of Mexico in Tultitln. The first bomb wounded a security guard; the second was identified and disposed of before anyone could be hurt. Last December, the group struck again this time at the Polytechnic University of Pachuca, where a package containing gunpowder exploded in the hand of a teacher, causing minor burns (see 'A litany of letter bombs'). No other developing country has suffered a comparable string of anti-technology attacks.
One year on from the bombing at Monterrey Tec, the repercussions are still being felt. Armando Herrera Corral and Aceves will not speak to Nature about what happened. It's too sensitive, you understand? is all Aceves would say. Herrera has left his job as director of the university's technology park and is now head of postgraduate studies. Other Mexican universities with nanotechnology research programmes have evacuated campuses in response to bomb threats, and universities across the country have introduced stringent security measures. Some researchers are anxious for their own safety; some are furious about being targets. But all the researchers that Nature spoke to in Mexico are adamant that the attacks will not discourage them from their research or dissuade students from entering the field.
So far, there has been little explanation of where the vitriol is coming from. Why are radical environmental groups targeting nanotechnology? Is this field being confronted with the same sort of militant hostility that has dogged genetic-modification research and animal testing? And why Mexico?
