SIRTE, Libya (Reuters) - African states lack the resources to deal alone with climate change and must share water better to feed growing populations, government ministers said at a water conference in Libya on Wednesday.

TOKYO (Reuters) - Japanese researchers have reproduced images of things people were looking at by analyzing brain scans, opening the way for people to communicate directly from their mind.
