Wildfires in California have forced thousands of people to evacuate their homes. High winds and hot weather are causing difficulties for the 3,000 firefighters tackling the blazes in the south and centre of the state.
Scientists at Nottingham University say they are confident that cloned animals do not age prematurely. That’s raised hopes that cloning as part of medical research might lead to major advances. The first animal cloned from an adult cell, known as Dolly the sheep, did die prematurely. Researchers say her four cloned siblings are in good health.
