全球小麦供应或受新病菌威胁(有声)
这种名为UG-99的由风传播孢子的菌类是十年前在东非被发现的。科学家在俄国举行的一个会议上说，由于它的蔓延程度极其迅速，所以控制它很困难。
这种菌在过去几年中，已经在肯尼亚摧毁了大约80%的小麦作物。虽然科学家已经开发出抗菌的新小麦品种，但最新的菌株却能击败这种抗菌能力。

The oil company BP says it's started a critical attempt to plug the damaged well that has been leaking huge amounts of oil into the Gulf of Mexico. The operation has never been tried before. Rajesh Mirchandani in Louisiana has the details.
More than five weeks since the rig explosion that killed 11 people and caused the leak, BP is beginning its latest attempts to plug the well. The so-called "top-kill" method involves shooting large amounts of dents fluid called drilling mud into the well. The hope is that the pressure of the mud will be granted them onto the escaping oil and slow or stop the leak. Then cement will be pumped in on top to seal off the well for good. BP says chances of success are 60 to 70 percent.
Earlier, BP acknowledged that there had been a whole series of failures before the explosion that caused the spill. To leading congressmen, have meanwhile said BP documents, indicated there were several warning signs before the accident, but action appears to have been taken too late.
The Jamaican Prime Minister Bruce Golding says there will be an independent investigation into the death of at least 44 people in the capital Kingston. They were killed in battles between civilians and security forces, searching for Christopher "Dudus" Coke, an alleged drug lord wanted in the US. Jamaica's Information Minister Daryl Vaz told the BBC they were looking into allegations of human rights abuses by the authorities.
"The reports have become odd, farce and furious in terms of accuses based on human human rights. But I would want to pray judge this particular situation. It's an operation, that's ongoing."
Christopher Coke is believed to be hiding in an area of the capital where residents say they are running out of food, water and medication after being confined to their home since the search began on Monday.

Scientists have warned that the global supply of wheat could be under threat from a new strain of fungus which can destroy an entire harvest. Known as UG99, the fungus is already endemic in Kenya where it's destroyed around 80% of the wheat crop over several seasons. Our science reporter Matt Mcgrath has more.
The reddish-brown wind-borne pathogen was discovered a decade ago in east Africa. It attacks the crop's vascular tissue, causing the wheat plant to fall over and can lead to the loss of entire harvest. Scientists have successfully developed new varieties of wheat which are resistant to the original fungus. But these latest strings have overcome this resistance. Researchers say that the speed which the fungus moves makes it difficult to control. It can travel 160 kilometres in a day. The big worry now is that research suggests the fungus is on the march.
