Increased CO2 and Rice Nutrition
New research suggests that rice will be depleted in important B vitamins and minerals by rising CO2 levels in the atmosphere. Adam Rutherford to talks to Kristie Ebi of the University of Washington, one of the scientists behind the finding, and Marco Springmann of the Future of Food project at the University of Oxford.

GDPR
Legislation to greater protect individuals’ data in the EU has come into force. What does it mean, and will there be unexpected consequences for the use of metadata? Gareth Mitchell talks to Claire Bury from the EU commission and Luukas Ilves, Deputy Director at The Lisbon Council.

Polio Vaccination
As vaccinations start in the Democratic Republic of Congo to try to contain the ebola outbreak, scientists in the United States have published research which they hope will help to simplify immunisations against diseases like polio. Eradication is tricky because the vaccine needs to be given in multiple doses. However, researchers at MIT say they have successfully vaccinated animals with just one injection. Claudia Hammond speaks to researcher Ana Jaklenec.

Feel Good Garden

African Bee Parasites
The presence of queen bees in a hive prevents them from being taking over by ‘parasite’ bees, a new study has found. Fiona Mumoki of the University of Pretoria explains to Roland Pease how the parasitic bees take over queenless hives, eventually causing hive collapse, and how the presence of a queen can enable hive fight back against the parasites.

Drone Dog Rescue
An engineer in India repurposed a drone to rescue a puppy that had fallen into a gully in New Delhi. Milind Raj constructed a giant claw that was attached to the drone. Raj says it took him six hours to assemble the improvised aerial vehicle.
