LONDON (Reuters) - Field trials are under way in England of a genetically modified (GM) wheat that strikes fear into aphids and attracts a deadly predator to devour them, providing an alternative to the insecticides now used to control the crop pest. The wheat emits a pheromone which aphids release when they are under attack to create panic and prompt the insects to flee, John Pickett, scientific leader of chemical ecology at Rothamsted Research in eastern England, said on Wednesday

By Nina Chestney LONDON (Reuters) - Traditional measures showing strong economic growth in Brazil and India over nearly two decades fail to take account of the depletion of their natural resources, scientists and economists at a climate conference said on Wednesday. Scientists and environment groups have been pressuring governments to include the value of their countries' natural resources - and use or loss of them - into future measurements of economic activity, rather than relying solely on the gross domestic product calculation

By Joseph Logan SANAA (Reuters) - With a belch of acrid, greasy smoke and a jolt that shakes its moorings, the pump on Yemeni water farmer Jad al-Adhrani's plot of land roars to life, and the race to squeeze the last drop of water out of Yemen's parched earth resumes. Gesturing across his dusty patch of ground in Hamal, on the outskirts of the capital Sanaa, he counts himself lucky to still be drawing water after having dug down only 500 metres, but knows that it cannot last. "When it runs out," he says, "I'll dig again." The water he sells for drinking and washing to residents of the affluent neighboring Sanaa district of Hadda comes from an aquifer that thousands of wells studding the city and surrounding hills have sucked nearly dry.

By Nina Chestney LONDON (Reuters) - Dwindling supplies of metals, water and biomass could slow the deployment of clean energy technologies by 2035, a study by research organization the Stockholm Environment Institute and by business initiative 3C showed on Tuesday. Governments and companies are increasingly developing low-carbon technologies to reduce their dependency on fossil fuel-based energy sources and to cut greenhouse gas emissions.

LONDON -- The impact of human activity on the Earth is running out of control, and the amount of time in which action can be taken to prevent potentially catastrophic climate change is rapidly dwindling, a leading scientist from the Australian National University told a global scientific climate conference in London yesterday.
