Maximum Pain is Aim of New U.S. Weapon
    By David Hambling

The US military is funding development of a weapon that delivers a bout of
excruciating pain from up to 2 kilometres away. Intended for use against
rioters, it is meant to leave victims unharmed. But pain researchers are
furious that work aimed at controlling pain has been used to develop a
weapon. And they fear that the technology will be used for torture.

"I am deeply concerned about the ethical aspects of this research," says
Andrew Rice, a consultant in pain medicine at Chelsea and Westminster
Hospital in London, UK. "Even if the use of temporary severe pain can be
justified as a restraining measure, which I do not believe it can, the
long-term physical and psychological effects are unknown."

The research came to light in documents unearthed by the Sunshine Project,
an organisation based in Texas and in Hamburg, Germany, that exposes
biological weapons research. The papers were released under the US's
Freedom of Information Act.

One document, a research contract between the Office of Naval Research and
the University of Florida in Gainesville, US, is entitled "Sensory
consequences of electromagnetic pulses emitted by laser induced plasmas".

It concerns so-called Pulsed Energy Projectiles (PEPs), which fire a laser
pulse that generates a burst of expanding plasma when it hits something
solid, like a person (New Scientist print edition, 12 October 2002). The
weapon, destined for use in 2007, could literally knock rioters off their
feet.


Pain trigger

According to a 2003 review of non-lethal weapons by the US Naval Studies
Board, which advises the navy and marine corps, PEPs produced "pain and
temporary paralysis" in tests on animals. This appears to be the result of
an electromagnetic pulse produced by the expanding plasma which triggers
impulses in nerve cells.

The new study, which runs until July and will be carried out with
researchers at the University of Central Florida in Orlando, aims to
optimise this effect. The idea is to work out how to generate a pulse
which triggers pain neurons without damaging tissue.

The contract, heavily censored before release, asks researchers to look
for "optimal pulse parameters to evoke peak nociceptor activation" - in
other words, cause the maximum pain possible. Studies on cells grown in
the lab will identify how much pain can be inflicted on someone before
causing injury or death.


Long-term risk

New Scientist contacted two researchers working on the project. Martin
Richardson, a laser expert at the University of Central Florida, US,
refused to comment. Brian Cooper, an expert in dental pain at the
University of Florida, distanced himself from the work, saying "I don't
have anything interesting to convey. I was just providing some background
for the group." His name appears on a public list of the university's
research projects next to the $500,000-plus grant.

John Wood of University College London, UK, an expert in how the brain
perceives pain, says the researchers involved in the project should face
censure. "It could be used for torture," he says, "the [researchers] must
be aware of this."

Amanda Williams, a clinical psychologist at University College London,
fears that victims risk long-term harm. "Persistent pain can result from a
range of supposedly non-destructive stimuli which nevertheless change the
functioning of the nervous system," she says. She is concerned that
studies of cultured cells will fall short of demonstrating a safe level
for a plasma burst. "They cannot tell us about the pain and psychological
consequences of such a painful experience."
