Serendipity broadens the scope for making graphite

Curtin University researchers have discovered a new method for creating crystalline graphite using an Atomic Absorption Spectrometer, without the need for metal catalysts or special raw materials. The technique was developed by Master-level student Jason Fogg, who used short fast pulses to heat samples to extreme temperatures.

Shining light into the dark

Researchers have developed a new method to analyze microscopic samples without using external light, reducing interference and damage to living specimens. The 'glow in the dark' approach uses chemical stimuli to activate chemicals, enabling precise control over localized oxidative hotspots.

Curtin study could rewrite Earth's history

Researchers from Curtin University have found evidence that the Earth's first continents were not formed by subduction in a modern-like plate tectonics environment. The team measured iron and zinc isotopes in rocks sourced from central Siberia and South Africa, suggesting an alternative formation process.

Remixed mantle suggests early start of plate tectonics

Researchers have found evidence of a major 'stirring up' in the mantle layer around 3.2 billion years ago, indicating the start of global plate tectonic activity. This discovery has implications for our understanding of the evolution of life on Earth and the formation of mineral and energy resources.

On the hunt for megafauna in North America

Research from Curtin University analyzed ancient DNA to understand the causes of animal extinctions during the Ice Age. The study found that while plant diversity recovered as climate warmed, large animal diversity did not recover, suggesting human hunting was a major factor in megafauna extinction.

Tiger snakes tell more about local wetlands' pollution levels

A study by Curtin University found that tiger snakes living in Perth's urban wetlands are accumulating toxic heavy metals in their livers, suggesting habitat contamination. The snakes' bioaccumulation of heavy metals through eating frogs indicates the wetlands' pollution levels are a concern for local biodiversity.

eDNA provides researchers with 'more than meets the eye'

Researchers used eDNA metabarcoding to detect biodiversity in two regions of Western Australia, finding that bulk arthropods and animal droppings detected the most species. The study suggests that eDNA can be a fast and accurate tool for biomonitoring, but careful surveys are needed to avoid contamination from outside organisms.

Turbulent times revealed on Asteroid 4 Vesta

Researchers from Curtin University analyzed volcanic meteorites from Antarctica to understand Asteroid Vesta's geological history. The study found that Vesta was volcanically active for at least 30 million years after its formation, contradicting previous models and suggesting pockets of magma survived on the asteroid.

Nile River monitoring influences northeast Africa's future

Curtin University research monitors Nile River water volume to help 200 million North-East Africans plan for sustainable use of resources. The study uses GRACE satellite data to isolate total water storage, providing independent insights for countries to inform decision-making and reduce reliance on the river's precious water supply.

Violent solar system history uncovered by WA meteorite

A Curtin University study of a WA meteorite has shed light on the solar system's bombardment history, revealing that asteroid collisions ceased after 3.4 billion years ago due to asteroids being too small or protected by regolith. The research suggests that impacts stopped occurring after this period and remain unchanged until now.

New York squirrels are nuts about city life

Research shows eastern grey squirrels modify their behaviour when approached by humans, reducing unnecessary responses and improving urban survival. The study highlights the importance of understanding animal adaptations to urbanization, enabling conservation efforts and habitat management.

Ancient DNA shows moa were fine until humans arrived

A study analyzing ancient DNA from over 250 radiocarbon-dated moa samples reveals that the iconic New Zealand bird was thriving when humans arrived, contradicting previous theories of population collapse before human arrival. The research suggests human activities contributed to the moa's extinction.

Gravity variations much bigger than previously thought

A joint Australian-German research team has created the highest-resolution maps of Earth's gravity field, showing variations up to 40 percent larger than previously assumed. The new maps were calculated at three billion points and will improve civil engineering projects such as building canals, bridges, and tunnels.
