Why don’t people care about Australia’s native rodents? The problem could be their ugly names
Native rats and mice don’t usually evoke sympathy among the Australian public. The common names for the species – such as swamp rat – do little to help.

NZ has the energy resources to adopt alternative food technologies – it just needs a plan
Cultured meats, precision fermentation and other cutting-edge technologies are predicted to disrupt conventional agriculture. Despite the threat, New Zealand is well positioned to ride the wave.

How the weird and wonderful microbes in wastewater can make our cities more sustainable
Much like our gut microbes, the community of microbes used to process human waste must be healthy to do the job well. Monitoring the DNA in waste sludge can help us ensure the system stays healthy.

We once killed 600,000 koalas in a year. Now they’re Australia’s ‘teddy bears’. What changed?
A century ago, millions of koalas were killed for their fur. The backlash was fierce.

Allowing duck hunting to continue in Victoria is shameful and part of a disturbing trend
Victoria’s decision this week to reject a ban on duck hunting is a shot to the heart for proud Yuin man Jack Pascoe, son of Bruce Pascoe. The black duck Yumburra is a Yuin tribal totem.

Stop killing brown snakes – they could be a farmer’s best friend
The benefits of snake populations on agricultural land far outweigh the potential costs, and farmers should tolerate rather than kill them.

Sediment runoff from the land is killing NZ’s seas – it’s time to take action
Over 200 million tonnes of sediment are transported by rivers to the sea each year, the most widespread water contaminant in the country. Its devastating impact on marine life has to be reversed.

Do we want a wind farm outside our window? What Australians think about the net zero transition
Australians want government to act on climate change, but not necessarily now, or in their neighbourhood. How can governments resolve this dilemma?

Flying foxes pollinate forests and spread seeds. Here’s how we can make peace with our noisy neighbours
If a colony of flying foxes sets up in your backyard, you might be annoyed – or concerned. But these gentle bats are vital to our forests.

Prince Albert had nothing to do with the lyrebird bearing his name. Should our birds be named after people?
Birds have one unchanging scientific name, but often many common names that are subject to change. Choosing a new name for a bird isn’t necessarily a simple decision.

As another cyclone heads for Queensland, we must be ready for the new threat: torrential rain and floods
The new threat from cyclones can come from behind you – flooding from more intense rainfall.

Did the BOM get it wrong on the hot, dry summer? No – predicting chaotic systems is probability, not certainty
We crave certainty in our weather forecasts. But that’s only possible for big weather events such as cyclones and major storms. Everything else is probability.

How Australia's huge superannuation funds can do much more to fight climate change, with a little help
Our super funds say they want to invest more in the net zero transition but that regulation blocks them. It’s time to put them to the test, and turn their piles of money toward a greener future.

'It’s not game over – it’s game on': why 2024 is an inflection point for the climate crisis
Without urgent action, Earth is heading for climate catastrophe. Yet there are reasons for hope in 2024 – including a possible peak in global greenhouse gas emissions.

When floodwater reaches the sea, it can leave a 50 metre thick layer of brown water – and cause real problems
Floodwaters pulsing into the sea normally clear within six days. But the 2022 floods in eastern Australia were different.

It is time to draw down carbon dioxide but shut down moves to play God with the climate
To fight global warming we will soon have to try to remove carbon dioxide from the skies or find ways to reflect the Sun’s heat. Such radical paths must be examined, but risky experiments avoided.

1 billion people left dangerously exposed to heat stress by gaps in climate monitoring
Most of the 1 billion people in informal settlements are in the tropics where the threat of humid heat is rising. Poor weather station coverage that misses local hotspots puts them even more at risk.
