Deadly harvest: The Lebanese fields sown with cluster bombs
We went to Yohmor to find where Hussein Ali Ahmad had received his terrible wounds while pruning his orange tree. The village is at the end of a broken road, six miles south of Nabatiyeh, and is overlooked by the ruins of Beaufort Castle, a crusader fortress on a ridge above the deep valley along which the Litani river runs.
Israeli bombs and shells have turned about a third of the houses in Yohmor into concrete sandwiches, one floor falling on top of another under the impact of explosions. Some families camp in the ruins. Villagers said that they were most worried by the cluster bombs still infesting their gardens, roofs and fruit trees. In the village street, were the white vehicles of the Manchester-based Mines Advisory Group (MAG), whose teams are trying to clear the bomblets.
It is not an easy job. Whenever members of one of the MAG teams finds and removes a bomblet, they put a stick, painted red on top and then yellow, in the ground. There are so many of these sticks that it looks as if some sinister plant had taken root and is flourishing in the village.
"The cluster bombs all landed in the last days of the war," said Nuhar Hejazi, a surprisingly cheerful 65-year-old woman. "There were 35 on the roof of our house and 200 in our garden so we can’t visit our olive trees." People in Yohmor depend on their olive trees and the harvest should begin now before the rains, but the trees are still full of bomblets. "My husband and I make 20 cans of oil a year which we need to sell," Mrs Hejazi says. "Now we don’t know what to do." The sheer number of the bomblets makes it almost impossible to remove them all.
Frederic Gras, a de-mining expert formerly in the French navy, who is leading the MAG teams in Yohmor, says: "In the area north of the Litani river, you have three or four people being killed every day by cluster bombs. The Israeli army knows that 30 per cent of them do not explode at the time they are fired so they become anti-personnel mines."
Why did the Israeli army do it? The number of cluster bombs fired must have been greater than 1.2 million because, in addition to those fired in rockets, many more were fired in 155mm artillery shells. One Israeli gunner said he had been told to "flood" the area at which they were firing but was given no specific targets. M. Gras, who personally defuses 160 to 180 bomblets a day, says this is the first time he seen cluster bombs used against heavily populated villages.
An editorial in Haaretz said that the mass use of this weapon by the Israeli Defence Forces was a desperate last-minute attempt to stop Hizbollah’s rocket fire into northern Israel. Whatever the reason for the bombardment, the villagers in south Lebanon will suffer death and injury from cluster bombs as they pick their olives and oranges for years to come.

Researchers work on turning CO2 into fuel
Chemists have long hoped to find a method of bringing the combustion of fuel full circle by turning CO2 back into useful hydrocarbons. Now researchers at the University of Messina in Italy have developed an electrocatalytic technique they say could do the job, reports New Scientist (16 September 2006, p.30).
"Not a dream": "The conversion of CO2 to fuel is not a dream, but an effective possibility which requires further research," says team leader Gabriele Centi. The researchers chemically reduced CO2 to produce eight and nine-carbon hydrocarbons using a catalyst of particles of platinum and palladium confined in carbon nanotubes. These hydrocarbons can be made into petrol and diesel.
How it works: To begin with, the researchers used sunlight plus a thin film of titanium dioxide to act as a photocatalyst to split water into oxygen gas plus protons and electrons. These are then carried off separately, via a proton membrane and wire respectively, before being combined with CO2 plus the nano-catalyst to produce the hydrocarbons.
Better efficiency "possible": Although the nano-catalysts produced two or three times more hydrocarbons than a commercially available catalyst, the process converted only about 1 per cent of the CO2 at room temperature. Centi believes it will be possible to improve on that by using higher temperatures and a larger surface area of catalyst.
10 year target: It will also be necessary to boost the efficiency of the solar water-splitting, he says. With the right research, Centi believes that an efficient solar-powered reactor for converting CO2 into fuel could be available "within a decade".
EU funding: He presented his latest work, which is funded by the European Union, at a meeting of the American Chemical Society in San Francisco on 13 September.
"Worthwhile": Ian Plumb, who researches water-splitting reactions at the Australian national research institute CSIRO Industrial Physics, says that unless the efficiency is improved it will be too expensive to implement. "But there is no doubt that what they are trying to achieve is very worthwhile."
