Record Temperatures in Kuwait and US

Available for over a year

Last week Kuwait experienced a temperature of 54 degrees Celsius and the East Coast of the US had a heatwave. Roland Pease talks about the reasons for this extreme weather with Dr Gavin Schmidt, director of the Goddard Institute for Space Studies in New York. The first transatlantic telegraph cable to successfully link Ireland and Newfoundland is 150 years old this week. Rob Thompson visits John Liffen at the Science Museum in London to see some off cuts of the original cable. Professor Mark Miodownik explains how those pioneering engineers overcame problems and got the cables to work and Prof Polina Bayvel talks about how they transformed the Victorians’ lives. Jonathan Amos and Jonathan Webb of the BBC News Science team discuss with Roland Pease the legacy of the first round the world solar powered flight, Solar Impulse, and the discovery that the Great Red Spot on Jupiter is hot. Dolly the cloned sheep had a number of health problems. Professor Kevin Sinclair of Nottingham University and colleagues has now cloned sisters of Dolly to see if they have the same issues. Engineers at the Italian Institute of Physics are trying to get robots to learn in the way that children do. Rather than programming them, they give them the basic ability to toy with objects – and this way have got one to discover Archimedes principle – the idea that a heavy object dropped into a bucket will displace water and raise the surface. Vishuu Mohan is one of the masters, and iCub, his pupil, is built like a 30-month old. (Photo: The sun sets behind people taking a dip in the sea, Kuwait City.
