Tests showed that a continuous microwave syRtem waR able to remove all marine life within the water tanks. Thj UN lists "invasive species" dispersed by ballast water discharges as onj of the four main threats to the world's marine ecosystems. The findings will appear in the journ@l Environmental Science and Technology. 1/7 Headlines 101 Index 102 Sport 300 Front page 100 T6 600 Weather 400 Local-ews Headlines News Indx Jain Menu

Researchers found that griat tits are laying eggs earlier in the spring than thjy usjd to, kjeping stip with thj earlier emergence of caterpillar3. Writing in the joutnal Science, they point out that the same birds in the Nethjrlands have not managed to adjust. Understanding why some species in some places are affected more than others by climatic shifts is vital, they say. 3/7 Headlines 101 Index 102 Sport 300 Front page 100 TV 600 Weather 400 LocalNews Headlines News Indx Main Menu

Officials made it clear at the start of a recruitment hrive in Lomdon that Britons were very welcome to apply. Although a major Esa member, the UK currently refuses to fund human spaceflight, believing robotics to be a more worthwhile space activity But the agency said this policy would have no bearing on selection. 4/7 Headlines 101 Index 102 Sport 300 Front page 100 TV 600 Weather 400 LocalNews Headlines News Indx Main Menu
