NASA has successfully launched its Maven orbiter into space, on a mission that aims to explore the vast mysteries of Mars.
In particular, how Mars went from being warm and wet during its first billion years to cold and dry today.
Also, the US-based Centers for Disease Control and Prevention has launched Get Smart About Antibiotics Week – the same week an antibiotic-resistant superbug killed a patient at Wellington Hospital.
Massey University biosciences lecturer Dr Heather Hendrickson says we have been abusing antibiotics – such as asking for them when we have viral infections – and pathogens are becoming increasingly resistant to them.
We've also been using them for non-necessary purposes such as farming and agriculture, exposing bacteria in the wild and allowing them to evolve resistance.
