The submarine announcement is sure to trigger a new round of debate on whether nuclear energy is right for Australia. But let’s be clear: the technology makes no sense for Australia.

Under a new code, rural landholders in NSW will be allowed to clear up to 25 metres of land outside their property boundary. This will be devastating for the wildlife that live or migrate there.

The researchers found tooth shape varied, depending on the types of food a carnivore regularly bites into – in much the same way we choose a kitchen knife depending on what we’re cutting up.

The way we use fossil fuels is wasteful and inefficient. A world based on renewable energy would need half as much as we produce now. Robert McLachlan, Professor in Applied Mathematics, Massey University Licensed as Creative Commons – attribution, no derivatives.

The changing dynamic between Borneo’s pigs and Indigenous people is a powerful reminder of the fragility of the human-nature connection.

Dried foods are a staple in many Aussie diets, but the industry is under threat as recurring drought makes fruit and vegetables harder to process. Charith Rathnayaka, Lecturer in Mechanical Engineering, University of the Sunshine Coast Licensed as Creative Commons – attribution, no derivatives.

Roaming pet cats can kill more than 180 animals each year. But most people who keep cats inside do so for the welfare of their pet.

The phenomenon is called heliotropism, and sunflowers are most famous for it. But why do they track the sun? And how? Gregory Moore, Doctor of Botany, The University of Melbourne Licensed as Creative Commons – attribution, no derivatives.

Soundscapes impact the well-being of human and non-human urban inhabitants. Here’s how noise can change animal behaviour, both in and out of lockdown.

The world is moving away fossil fuels, and there’s nothing Australia can do about it. Racing to dig up and sell whatever fossil fuels we can before the timer stops is not a future-proof strategy.

Major research found Australia must keep 95% of coal in the ground to limit global warming. With a little political will, this would be easy to do. John Quiggin, Professor, School of Economics, The University of Queensland Licensed as Creative Commons – attribution, no derivatives.

Last month’s dire report by the Intergovernmental Panel on Climate Change may have left you feeling overwhelmed. But small changes at the household level really can make a world of difference.
