Martian meteorite"s organic materials origin not biological, formed by geochemical interactions between water and rock
Organic molecules found in a meteorite that hurtled to Earth from Mars were synthesized during interactions between water and rocks that occurred on the Red Planet about 4 billion years ago, according to new analysis led by Carnegie's Andrew Steele a.....»»
Magnetic avalanche triggered by quantum effects: "Barkhausen noise" detected for first time
Iron screws and other so-called ferromagnetic materials are made up of atoms with electrons that act like little magnets. Normally, the orientations of the magnets are aligned within one region of the material but are not aligned from one region to t.....»»
Less affluent countries found to be more prone to damage caused by biological invasions despite lower trade volume
Non-native species introduced mainly via increasing trade of goods and services have huge economic, health, and environmental costs. These "biological invasions" involve the intentional or unintentional transport and release of species beyond their n.....»»
New approach to monitoring freshwater quality can identify sources of pollution, predict their effects
The source of pollutants in rivers and freshwater lakes can now be identified using a comprehensive new water quality analysis, according to scientists at the University of Cambridge and Trent University, Canada......»»
Researchers discover key gene for toxic alkaloid in barley
All plants mediate their environmental interactions via chemical signals. An example is the alkaloid gramine produced by barley, one of the world's most widely-grown cereals. Gramine provides protection against herbivorous insects and grazing animals.....»»
NASA"s mission to an ice-covered moon will contain a message between water worlds
NASA's Europa Clipper spacecraft, headed to Jupiter's ice-covered moon Europa in October 2024, will carry a laser-etched message that celebrates humanity's connection to water. The message pays homage to past NASA missions that carried similar messag.....»»
Research unlocks supernova stardust secrets
Curtin University-led research has discovered a rare dust particle trapped in an ancient extra-terrestrial meteorite that was formed by a star other than our sun......»»
Study finds decline in the stability of water yield in watersheds
Extreme climatic events such as droughts, heat waves, and cold spells not only modify hydro-meteorological conditions but also alter the underlying characteristics (e.g., wildfires due to droughts changing the vegetation cover). Intense human activit.....»»
Future of 1 billion people in South Asia hinges on water pact, says new analysis
Better collaboration is urgently needed to mitigate the impacts of climate change on three key river basins in South Asia—the Brahmaputra, Indus and Ganges—according to new analysis......»»
Euclid space telescope’s vision cleared thanks to deicing
The Euclid Space Telescope is fully operational after a deicing procedure removed small amounts of water ice from its mirror......»»
Understanding cattle grazing personalities may foster sustainable rangelands
Not all cattle are the same when it comes to grazing. Some like to wander, while others prefer to stay close to water and rest areas......»»
Enhancing chickpea irrigation efficiency, yield and sustainability
A new study published by the Hebrew University of Jerusalem (HUJI) introduces a non-invasive technique for evaluating chickpea water status, offering farmers a powerful tool to fine-tune irrigation schedules and potentially elevate the sustainability.....»»
All of James Cameron’s movies, ranked
To celebrate the 40th anniversary of The Terminator, we're looking back at all of James Cameron's movies, from the beginning to Avatar: The Way of Water......»»
Rock-wallabies are "little Napoleons" when biting, thus compensating for their small size
Australian rock-wallabies are "little Napoleons" when it comes to compensating for small size, packing much more punch into their bite than larger relatives......»»
Advancing towards sustainability: Turning carbon dioxide and water into acetylene
Reaching sustainability is one of humanity's most pressing challenges today—and also one of the hardest. To minimize our impact on the environment and start reverting the damage humanity has already caused, striving to achieve carbon neutrality in.....»»
Researchers obtain promising results for control of pollutants in water
An article published in the journal Catalysis Communications describes a simple, efficient and sustainable approach to the degradation and quantitative monitoring of a mixture of polycyclic aromatic hydrocarbons (PAHs), emerging pollutants that conta.....»»
Study sheds light on the development of novel antidotes against nerve agents
A new article was published in Chemico-Biological Interactions by the Sustainable Chemistry and Engineering research group of Tallinn University of Technology in collaboration with colleagues from the Czech Republic, Brazil, and the UK. This study sh.....»»
Elephant hunting by early humans may explain proximity between extensive Paleolithic stone quarries and water sources
Archaeologists from Tel Aviv University have uncovered the mystery surrounding extensive Paleolithic stone quarrying and tool-making sites: Why did Homo erectus repeatedly revisit the very same locations for hundreds of thousands of years? The answer.....»»
Curbside collection improves organic waste composting, reduces methane emissions
Most organic household waste ends up in landfills, where it generates methane, a powerful greenhouse gas. Composting food and garden waste instead of sending it to landfills can significantly reduce methane emissions and help mitigate global warming......»»
Researchers harness the sun to produce hydrogen gas from water
A team of chemistry researchers at the University of North Carolina at Chapel Hill has developed a unique approach to harnessing the sun's energy to produce hydrogen gas, a potential clean energy source, from water, according to a paper published in.....»»
Manila confronts its plastic problem through a community-guided protocol
Governments and international organizations have touted the circular economy, in which materials and products stay in circulation for as long as possible, as an antidote to our global plastic problem. (The equivalent of 2,000 garbage trucks of plasti.....»»
