With current modes up against their limits, we need new data storage solutions. Tiny defects in diamonds’ atomic structure might turn them into a new medium for memory.

Increasing legume production can turn the tide for African farmers who struggle with poor soils, declining farm yields and worsening nutrition in one fell swoop
A groundbreaking new economic study has found that investing A$8.2 billion would get us very close to hitting targets to cut water pollution into the Great Barrier Reef by 2025.
Excess nutrients from farm fields cause widespread water pollution across the U.S. Bioreactors – essentially, ditches filled with wood chips – are emerging as a way to reduce nutrient pollution.
You’ve heard of cap-and-trade schemes for greenhouse gases. Perhaps we also need one to limit the amount of fertiliser runoff onto the Great Barrier Reef.
To fix pollution on the Great Barrier Reef, some farming practices will have to change.
Nitrogen inputs in African soil must be carefully used. If they’re not, there will be unintended consequences for the environment and human health.
The latest Great Barrier Reef report shows some improvements to water quality over the past five years, but there’s still a lot to do on one particular problem: nitrogen.
About 10% of human-generated greenhouse gas emissions come from farming. Researchers are working on ways to address this piece of the global warming puzzle.
Carbon dioxide is the “face” of the greenhouse gases, but nitrous oxide (N2O) merits its own spotlight. The same “laughing gas” once used by dentists as an anaesthetic and used today by people looking…
When we talk about greenhouse gases we usually talk about carbon dioxide. When media reports depict climate change, we invariably see the cooling towers of a coal power station. Which is fair, because…
One of nature’s most spectacular events occurs every autumn, when the leaves of hardwood trees burst into brilliant color before falling to the ground. These autumnal displays in the eastern United States…
Excessive use of nitrogen-based fertilisers in agriculture is contributing to nitrous oxide emissions. Leftover nitrogen…
Removing wastewater pollution through wetlands is, in at least one scenario, more cost effective than upgrading a treatment…
If Earth were like a human body, large animals might be its arteries, moving nutrients from where they’re abundant to where they’re needed. Currently the planet has large regions where life is limited…
Each year more than 1 million tonnes of mineral nitrogen fertiliser is applied to arable and grass crops in the UK. This pollutes waterways through nitrate run-off and the atmosphere from the release of…
Planet Earth has boundaries for its biophysical subsystems. By 2009, we had already exceeded three of the boundaries – climate change, biodiversity loss, and the nitrogen cycle. Climate change is a top-of-mind…
A state-of-the-art measurement tool developed by researchers at the Queensland University of Technology will greatly assist…
