Material: Medical Research bureaucracy, Corruption and Earthquakes, Music Moods

Medical research in the UK is being hampered by bureaucracy and burdensome regulation according to a report published this week. Quentin hears how damaging the delay can be to UK science and how things can be improved. Corruption is the leading cause of death in earthquakes according to seismologist Roger Bilham in this week's edition of Nature. Corrupt governments fail to enforce simple building regulations which could save many lives when the ground starts shaking, he argues. Quentin finds out about the global transparency index. Chills in music arise in the same way as cocaine-fuelled highs, according to neuroscientists. Tracking the mental, chemical and physiological changes of volunteers hearing their favourite music, the researchers found primitive 'reward' centres of the brain fire up at moments of peak emotion. Valorie Salimpoor, who led the research, reveals the ups and downs of the musical experience.
