Indian defence scientists are planning to put one of the world's hottest chilli powders into hand grenades.
They say the devices will be used to control rioters and in counter-insurgency operations.
Researchers say the idea is to replace explosives in small hand grenades with a certain variety of red chilli to immobilise people without killing them.
The chilli, known as Bhut Jolokia, is said to be 1,000 times hotter than commonly used kitchen chilli.
Australian wallabies are eating opium poppies and creating crop circles as they hop around "as high as a kite", a government official has said.
Lara Giddings, the attorney general for the island state of Tasmania, said the kangaroo-like marsupials were getting into poppy fields grown for medicine.
She was reporting to a parliamentary hearing on security for poppy crops.
