Published New approach needed to save Australia's non-perennial rivers



An extensive review of current research incorporating geomorphology, hydrology, biogeochemistry, ecology and Indigenous knowledges identifies prevailing factors that shape water and energy flows in Australia's non-perennial rivers -- but the review also points to research deficiencies that must be addressed if these river systems are to be preserved and protected.
Published Revolutionary molecular device unleashes potential for targeted drug delivery and self-healing materials



In a new breakthrough that could revolutionise medical and material engineering, scientists have developed a first-of-its-kind molecular device that controls the release of multiple small molecules using force.
Published New device gathers, stores electricity in remote settings



Wirelessly connected devices perform an expanding array of applications, such as monitoring the condition of machinery and remote sensing in agricultural settings. These applications hold much potential for improving the efficiency, but how do you power these devices where reliable electrical sources are not available? Research points to a possible solution in the form of a novel type of battery.
Published Tiny plastic particles are found everywhere



Microplastic particles can be found in the most remote ocean regions on earth. In Antarctica, pollution levels are even higher than previously assumed.
Published Impact of climate change on marine life much bigger than previously known



Fish and invertebrate animals are far more affected by warmer and more acidic seawater than was previously known. The big gain of the new method is that more details become known about effects of climate change on species.
Published Subterranean storage of hydrogen



Scientists are using computer simulations and laboratory experiments to see if depleted oil and natural gas reservoirs can be used for storing carbon-free hydrogen fuel. Hydrogen is an important clean fuel: It can be made by splitting water using solar or wind power, it can be used to generate electricity and power heavy industry, and it could be used to power fuel-cell-based vehicles. Additionally, hydrogen could be stored for months and used when energy needs outpace the supply delivered by renewable energy sources.
Published Humans converted at least 250,000 acres of estuaries to cities, farms in last 35 years



Worldwide over the past 35 years, dams and land reclamation activities converted 250,000 acres of estuary -- an area roughly 17 times the size of Manhattan -- to urban land or agricultural fields, with most land conversion and estuary loss in rapidly developing countries, a new study finds. The findings could help developing countries avoid problems faced by countries that have already lost or degraded their estuaries.
Published Atmospheric and economic drivers of global air pollution



Carbon monoxide emissions from industrial production have serious consequences for human health and are a strong indicator of overall air pollution levels. Many countries aim to reduce their emissions, but they cannot control air flows originating in other regions. A new study looks at global flows of air pollution and how they relate to economic activity in the global supply chain.
Published How climate change will impact food production and financial institutions



Researchers have developed a new method to predict the financial impacts climate change will have on agriculture, which can help support food security and financial stability for countries increasingly prone to climate catastrophes.
Published Deep parts of Great Barrier Reef 'insulated' from global warming -- for now



Some deeper areas of the Great Barrier Reef are insulated from harmful heatwaves -- but that protection will be lost if global warming continues, according to new research.
Published Boreal forest and tundra regions worst hit over next 500 years of climate change, study shows



Modelling climate change over a 500 year period shows that much of the boreal forest, the Earth's northernmost forests and most significant provider of carbon storage and clean water, could be seriously impacted, along with tundra regions, treeless shrublands north of the boreal forest that play a significant role in regulating the Earth's climate.
Published Scientists unveil cutting-edge ruthenium catalyst for new reaction discovery and optimization



Researchers have achieved a groundbreaking advancement in catalyst technology.
Published Using pulp and paper waste to scrub carbon from emissions



Researchers have come up with an innovative approach to improve the energy efficiency of carbon conversion, using waste material from pulp and paper production. The technique they've pioneered not only reduces the energy required to convert carbon into useful products, but also reduces overall waste in the environment.
Published Climate change threatens Antarctic meteorites



Antarctica harbors a large concentration of meteorites imbuing the icy continent with an unparalleled wealth of information on our solar system. However, these precious meteorites are rapidly disappearing from the ice sheet surface due to global warming, according to a new study.
Published How scientists are accelerating chemistry discoveries with automation



Scientists have developed an automated workflow that could accelerate the discovery of new pharmaceutical drugs and other useful products. The new automated approach could analyze chemical reactions in real time and identify new chemical-reaction products much faster than current laboratory methods.
Published Ocean waves propel PFAS back to land



A new study reveals that PFAS re-emit into the air from crashing ocean waves at levels comparable to or greater than other sources, establishing a cyclical transport process for these 'forever chemicals' between land and sea.
Published A simple, inexpensive way to make carbon atoms bind together



The active ingredient in many drugs is what's known as a small molecule: bigger than water, much smaller than an antibody and mainly made of carbon. It's tough, however, to make these molecules if they require a quaternary carbon -- a carbon atom bonded to four other carbon atoms. But now, scientists have uncovered a potential cost-effective way to produce these tricky motifs.
Published Chemical reactions can scramble quantum information as well as black holes



A team of researchers has shown that molecules can be as formidable at scrambling quantum information as black holes by combining mathematical tools from black hole physics and chemical physics and testing their theory in chemical reactions.
Published Heat stress from ocean warming harms octopus vision



While climate change has led to an increase in the abundance of octopuses, heat stress from projected ocean warming could impair their vision and impact the survivability of the species.
Published Rapid, simultaneous detection of multiple bacteria achieved with handheld sensor



A team has developed a method for simultaneous detection of multiple disease-causing bacterial species within one hour using a handheld device.
