Ebola; Ada Lovelace Day; Space Weather

Ebola Outbreak As the World Health Organisation announces that the situation in Guinea, Liberia and Sierra Leone is deteriorating, with widespread and persistent transmission of Ebola Virus Disease, the UK has introduced screening measures at Heathrow airport for passengers arriving from Ebola-affected countries. How has this particular outbreak become so widespread, and where did it start? Lucie Green discusses the source, spread and science of Ebola with Jonathan Ball, Professor of Molecular Virology at the University of Nottingham.

Ada Lovelace Day Leading the charge in inspiring and celebrating women scientists, technologists and mathematicians is 19th century computer programmer Ada Lovelace. Daughter of poet Lord Byron, collaborator with inventor Charles Babbage, and accomplished mathematician herself, October 14th has been set aside for Ada Lovelace Day. Event founder Suw Charman-Anderson tells us more.

Space Weather The Met Office Space Weather Operations Centre is designed to protect the UK from severe problems caused by space weather. It's been known since 1859 that weather in space can cause problems on Earth, but scientists say our growing dependence on technology puts us at greater risk. Our satellites, power grids and radio signals are all vulnerable to damage from extreme space weather events. Lucie Green heads down to the new space weather centre in Exeter, to see how they monitor the sun's activity, and how that translates into an extra-terrestrial forecast.
