Researchers studied the effects of different spin types on cricket ball trajectory. They found that adding top-spin to a delivery can reduce pitch length by up to 25cm, while introducing side-spin can produce significant drift. The study aims to help newcomers master spin-bowling and potentially benefit tennis players.
In a study of Purple-crowned Fairy-wrens, researchers found that females are more likely to initiate divorce due to dissatisfaction with their territory. Divorce allows females to gain better territories, which are crucial for reproductive success in this species.
A new Australian-first study found that nearly half of patients hospitalized due to diabetic foot disease were already showing symptoms. Diabetic foot disease causes significant costs, with estimated annual direct costs reaching $350 million for hospitalization alone.

A global study confirms that 90% of strokes can be prevented by modifying 10 modifiable risk factors, including hypertension, physical activity, and diet. The ranking of these factors varies by region, emphasizing the need for tailored strategies to reduce stroke risk.
A global study analyzing nearly 27,000 participants from every continent found that hypertension is the single most important modifiable risk factor for stroke, responsible for 47.9% of all strokes. The study also identified ten other modifiable risk factors that together account for 90% of strokes worldwide.

The discovery has applications beyond origins of life, including tracking atmospheric changes and finding economic metal deposits.
A study by researchers at Georgia State University found that firms perform better when CEO leadership style differs from the organization's culture. CEOs who adopt a similar style as the culture have a negative impact on performance. Instead, companies benefit from having different leadership and cultural styles.

A new study of the 37,000-year-old Deep Skull fossil has overturned long-held views about the early history of South-East Asia. The research finds that the remains likely belonged to an older woman and closely resemble Indigenous people of Borneo today, rather than Indigenous Australians.
European countries should not adopt Australia's immigration system, which perpetuates human rights abuses and torture in detention centers. The lack of transparency in the system is particularly concerning, with allegations of waterboarding, force-feeding, and restraints on asylum seekers surfaced.
A study by the University of Queensland found that spending 30 minutes or more in parks per week can reduce the risk of developing heart disease, stress, anxiety, and depression. The research suggests a minimum
Since gun law reform in 1996, Australia has seen an accelerating decline in intentional firearm deaths and an absence of fatal mass shootings. Key findings include a significant acceleration in the downward trend for firearm suicides and a non-significant acceleration in the downward trend in firearm homicides.
A new study from the University of Sydney reveals that nearly half of unexplained sudden cardiac deaths in young people (40%) had a clinically relevant genetic mutation, despite structurally normal hearts. The research also found that limiting strenuous physical activity may not reduce SCD among children and young adults, as most cases...

A study of mitochondrial genomes from the Huaca Pucllana site in Lima, Peru, found minimal genetic shift, indicating continuity of population over time. The Wari Empire's influence may have been exerted through cultural diffusion rather than population replacement.
An international team of scientists has detected a faint signal emitted by hydrogen gas in a galaxy over five billion light years away. The detection, achieved using the Very Large Array radio telescope, reveals an unusually large amount of hydrogen and provides insights into the history of galaxy evolution.
Researchers highlight the importance of fire-adaptive communities in managing wildfires, which have successfully coexisted with flames for centuries. These communities use social institutions to balance individual benefits with preservation of the common good, offering valuable lessons for designing local fire management strategies.
A new study reveals that male sparrows can distinguish between their faithful and unfaithful partners. When paired with an unfaithful female, males provide less food for their chicks. The research suggests that males make this decision based on the partner's behavior during fertile periods rather than detecting which chicks are theirs.
Researchers observe thousands of Hemiphlebia mirabilis in Australia, revealing a unique mating system and high sperm competition mechanisms. The species displays elaborate abdominal flicking displays, suggesting an advanced courtship behavior.
Researchers found that Australian small carpenter bee populations flourished in the wake of global warming following the last Ice Age. The study's findings suggest that bees have responded similarly to climate change globally, which could be a positive sign for their survival.
Researchers have identified a type of wild sorghum, known as Arun, which yields significantly more bioethanol than other varieties. The plant's stems contain high levels of a component thought to inhibit bioethanol production, but a high level of easily fermentable sugar negates this effect.
Children can learn robotics skills from a young age, with even pre-school students showing complex conceptual thinking and creativity. Robotics provides an engaging way for students and teachers to work together, promoting problem-solving and hands-on learning.
A team of Australian researchers has discovered the fossilized remains of a bizarre group of carnivorous marsupials that lived 15 million years ago. The newly found species, Malleodectes mirabilis, had an insatiable appetite for snails and was characterized by its powerful hammer-like premolar.

A Monash University-led research team has discovered that about half of the stars in the M4 globular cluster are dying prematurely, skipping the Red Giant phase and becoming White Dwarfs millions of years ahead of schedule. The cause of this phenomenon remains a mystery, but it is believed to only occur in sodium-rich/oxygen-poor stars.
Researchers at UNSW have developed a new solar cell configuration that delivers a world-record 34.5% efficiency in sunlight-to-electricity conversion, nudging closer to the theoretical limits of such devices. The device uses a four-junction mini-module with a hybrid receiver to extract maximum energy from unfocussed sunlight.
Scientists have discovered evidence of a huge asteroid that struck the Earth 3.46 billion years ago, creating massive earthquakes, tsunamis, and volcanic activity. The impact is believed to be one of the largest in human history, with the asteroid estimated to be 20-30 kilometers across.
Researchers at ANU found that New Zealand possums prefer leaves with high available protein content to eat, which can help limit their impact on native forests. This knowledge could inform targeted control programs to manage the possum population and protect sensitive tree species.
International research found a direct link between continued marijuana use during pregnancy and pre-term birth, with 6% of pre-term births potentially preventable. Marijuana use was independently associated with a five-fold increase in pre-term birth risk, regardless of other risk factors.
A new study published in Nature found that Earth's ancient upper atmosphere contained about the same amount of oxygen as today, with a methane haze layer separating the oxygen-rich upper layer from the lower, oxygen-starved atmosphere. This challenges the accepted view that Earth's ancient atmosphere was oxygen-poor.
The discovery of the world's oldest-known axe in Australia pushes back the date of hafted axes by thousands of years. Early Aboriginal technology was not as simple as previously thought, with evidence suggesting it developed in Australia after people arrived around 50,000 years ago.
A team of archaeologists from the University of Sydney has discovered a piece of the world's oldest axe, which dates back to a Stone Age period of 45,000 to 49,000 years ago. The axe fragment was found in Western Australia and reveals that the first Australians were technological innovators.
Researchers found that storms are shrinking in space and intensifying over smaller areas, resulting in more intense peak rainfalls. This intensification is expected to lead to a significant rise in flash flooding across major urban centers worldwide.
Research team led by Loïc Pellissier showed that continental plate movement drove the evolution of new species in coral reefs. The study used computer models and combined different simulations to demonstrate how shallow and warm waters were located throughout Earth history, giving corals a habitat.
