AFP: Suspended animation coming to life: researcher: "A gas proven deadly in chemical weapons could one day be used to put people into life-saving suspended animation.

While hydrogen sulfide is toxic in large doses, small amounts of the gas have the potential to make animals appear dead for a while then allow them to wake up unharmed, according to biochemist Mark Roth.

'I think we are on the path of understanding metabolic flexibility in a significant way,' said Roth, whose work at an eponymous lab in Washington State has gotten funding from a research arm of the US Department of Defense.

'In the future an emergency medical technician might give hydrogen sulfide to someone suffering serious injuries and they might become a little more immortal giving them time to get the care they need.'"
