Warmer nights prompt birds to lay eggs earlier

As climate change continues to cause temperatures to rise, the breeding patterns of birds such as blue tits are being altered as evenings in spring get warmer, researchers say.

Genetic legacy of rare dwarf trees is widespread

Researchers from Queen Mary University of London have found genetic evidence that one of Britain's native tree species, the dwarf birch found in the Scottish Highlands, was once common in England.

Scientists are trying to engineer apples so that the most widely consumed fruit in Europe no longer triggers allergic reactions. But would people want to eat them?
