This week on Science Weekly Ian Sample talks to Nasa scientist Jack Connerney about the five-year Juno mission to discover more about Jupiter's core and magnetosphere.
Alok Jha meets Professor Julian Ma, a molecular immunologist who is investigating whether genetically modified tobacco plants can be used to produce anti-HIV drugs. Professor Ma and his team at St George's Hospital Medical School in London have just received the green light in Europe to carry out a clinical trial of the antibody produced by his plants.
Finally, Ian and Alok discuss some of this week's other science news including controversy over whether "ghostwritten" research papers are fraudulent, and the truth about vampire bats' ability to locate a vein in their prey.
