Dr Shane, Dr Ailie and Dr Krystal discuss this week's hot science stories, including storing carbon dioxide in volcanic rock, a global atlas of light pollution, and the Juno spacecraft's pending arrival at Jupiter.

The team talk to Jennifer Walz from the Florey Institute, about her group's research, involving a new method of analysing brainwave data to determine the sequence that different brain regions are activated during a patient's seizure, which can be used to customise treatments for each patient.

They also interview Jane Visvader from the Walter and Eliza Hall Institute, whose research team's studies have revealed that breast cells develop two nuclei as the breast switches on lactation to nurture the newborn.

Finally, that talk with Professor Elizabeth Hartland, the Head of the Department of Microbiology and Immunology at the University of Melbourne, and Deputy Director, Peter Doherty Institute for Infection and Immunity. Her team believe they have found a major response that helps keep the Legionella infection at bay. With this discovery, they have dissected the complex roles of legions of immune cells that interact to destroy the bacterium. This would enable patients to have a more accurate prognosis for the infection, giving vital information about when to use antibiotics.
