February carbon dioxide levels average 400ppm for first time

We have hit a new milestone in carbon dioxide levels: the average for February topped 400ppm. It's the first time this has happened in the northern winter, when levels are typically lower than in summer.

Bushfires kill, but knowing exactly how might make them less deadly

The latest round of bushfires, which claimed 27 homes in the Adelaide Hills, has once again highlighted the importance of planning for the worst. Mercifully, no human lives were lost, and it will be important…

Explainer: what is raw milk and why is it harmful?

Milk is a highly nutritious food, and an important source of amino acids and minerals such as phosphorus and calcium, which contributes to bone health. Historically, milk was prone to contamination by…

Explainer: the RV Investigator’s role in marine science

We know more about the surface of the moon than we do about our deepest oceans, and only 12% of the ocean floor within Australia’s Exclusive Economic Zone has so far been mapped. The reason for this is…

A new way to fix those frustrating websites

How many times have you been looking for information online, only to find yourself going round and round in circles? Or you’ve spent too long poking around a website trying to find what you need, only…
CSIRO’s solar-concentrating mirrors can be used for several purposes, including creating high-energy ‘SolarGas’. CSIRO

Australia should export more ideas and fewer greenhouse emissions

As climate negotiators meet at the United Nations' Lima summit, which comes hot on the heels of the landmark US-China climate deal, there is a renewed focus on how the world can move to a lower-emissions…
Honeybees pollinate a third of Australia’s food crops. Losing them due varroa might would cost the economy billions of dollars. David McClenaghan

Australian farmers face increasing threat of new diseases: report

A nationwide outbreak of foot and mouth disease; an invasion of a devastating wheat disease; our honeybees completely wiped out. These are just three possible disastrous scenarios facing Australia; they’re…

Urbanisation brings animals and diseases closer to home

Our world is becoming increasingly urbanised. In 1950, just 30% of the world’s population lived in urban areas. This number is now over 50% and rising. By 2050, two-thirds of the world’s population are…

Go with the grain: technology to help farmers protect crops

New technology to tackle biosecurity challenges down the track is one of the five megatrends identified in today’s CSIRO report Australia’s Biosecurity Future: preparing for future biological challenges…

Ozone hole closing for the year, but full recovery is decades away

Imagine an environmental crisis caused by a colourless, odourless gas, in minute concentrations, building up in the atmosphere. There is no expert consensus, but in the face of considerable uncertainty…

Insects are the great survivors in evolution: new study

The time and date of the origin of insects and their pattern of evolution and survival over millions of years is revealed in a new study, published today in Science magazine. Insect relationships have…
Bats can harbour viruses such as Ebola and don’t display clinical signs of disease. Janelle Lugge

Bat’s immunity may hold key to preventing future Ebola outbreaks

Bats are the natural host species for Ebola and a variety of viruses, many of which can be fatal when transmitted to humans. More than 100 viruses have been identified in bats and this number is rising…
A new study shows plants may absorb more carbon than we thought. Jason Samfield/Flickr

Plants absorb more CO2 than we thought, but …

Through burning fossil fuels, humans are rapidly driving up levels of carbon dioxide in the atmosphere, which in turn is raising global temperatures. But not all the CO2 released from burning coal, oil…
