Environment

Giving up your car can be a difficult thing to consider, even for someone who mostly uses public transport. But an Australian company is working hard to change people's ideas about car ownership, by offering a twist on car-sharing. Members who join the scheme can access a fleet of cars, parked in designated locations throughout the city, paying by the hour when they need to go for a drive. Dacia Herbulock met the scheme's founder, Bruce Jeffries, and went for a test drive with a woman who's considering joining up.

Science

In-vitro fertilization (IVF) has been used for nearly three decades now, but there is little research on the long-term outcomes for IVF children. Now, a team of researchers in New Zealand found that there are indeed differences between children conceived naturally or through IVF. Veronika Meduna spoke to Wayne Cutfield, a professor of pediatric endocrinology at the University of Auckland, and Paul Hofman, the clinical director of endocrinology at the Starship Children's Hospital.

Out-sourcing is rampant - even in the bird world. Cuckoos and cowbirds are lazy parents and lay their eggs in other birds' nests. But why do these birds put up with it? Amelia Nurse spoke to Mark Hauber, a senior lecturer in animal behaviour at the University of Auckland. He's been researching this avian parental avoidance tactic - called brood parasitism. His findings, published in the Journal of Animal Ecology, indicate that the behaviour which facilitates parasite attacks is inherited.
