This week we discover what turns sperm 'on', investigate the true colour of dinosaurs and reveal how mosquitoes use their sense of smell. We also find out why bottled mineral water may not be as safe to drink as we assume, and how a study in Uganda and Zimbabwe showed that ARV drug monitoring regimes could be altered to enable more HIV patients to have access to these drugs. Plus, we time our seasons, in Question of the week!
