For the first time since the current Israel-Gaza conflict began in October, the UN Security Council has called for a ceasefire in Gaza. And the government's watered down some fuel efficiency standards in its proposed climate laws for cars. Will it make it easier for young people to buy an EV? Plus, the WA government has announced what it reckons are the "toughest" rules on selling nitrous oxide canisters - or nangs - in Australia. So will it actually stop people ripping nangs?
