Published Antarctic-wide survey of plant life to aid conservation efforts



The first continent-wide mapping study of plant life across Antarctica reveals growth in previously uncharted areas and is set to inform conservation measures across the region. The satellite survey of mosses, lichens and algae across the continent will form a baseline for monitoring how Antarctica's vegetation responds to climate change.
Published Greenland fossil discovery reveals increased risk of sea-level catastrophe



Seeds, twigs, and insect parts found under two miles of ice confirm Greenland's ice sheet melted in the recent past, the first direct evidence that the center -- not just the edges -- of the two-mile-deep ice melted away in the recent geological past. The new research indicates that the giant ice sheet is more fragile than scientists had realized until the last few years -- and reveals increased risk of sea-level catastrophe in a warmer future.
Published Forecasting climate's impact on a debilitating disease



In Brazil, climate and other human-made environmental changes threaten decades-long efforts to fight schistosomiasis, a widespread and debilitating parasitic disease. Now, researchers have developed models that can predict how the disease risk will shift in response to environmental changes.
Published First measurement of electron- and muon-neutrino interaction rates at the highest energy ever detected from an artificial source



Understanding neutrino interactions is crucial for obtaining a complete picture of particle physics and the universe. To date, neutrino interaction cross sections have not been measured at high energy above some hundred gigaelectronvolts at particle colliders. Now, researchers have obtained the first direct observation of electron and muon neutrino interactions in the Teraelectronvolt range at CERN's Large Hadron Collider, using the FASER detector. This study marks a significant step for particle physics research.
Published New model refutes leading theory on how Earth's continents formed



Computational modeling shows that plate tectonics weren't necessary for early continents.
Published How the rising earth in Antarctica will impact future sea level rise



The rising earth beneath the Antarctic Ice Sheet will likely become a major factor in future sea level rise, a new study suggests.
Published Link between global warming and rising sea levels



A new study suggests that Earth's natural forces could substantially reduce Antarctica's impact on rising sea levels, but only if carbon emissions are swiftly reduced in the coming decades. By the same token, if emissions continue on the current trajectory, Antarctic ice loss could lead to more future sea level rise than previously thought.
Published Born to modulate: Researchers reveal origins of climate-controlling particles



Aerosol particles imbue climate models with uncertainty. New work reveals where in the world and under what conditions new particles are born.
Published Sea level changes shaped early life on Earth, fossil study reveals



Shifts in the Earth's continental plates that drove long-term changes in sea level set the stage for the evolution of the earliest animals on Earth, a study suggests.
Published Combined effects of plastic pollution and seawater flooding amplify threats to coastal plant species



A new study highlights how a combination of environmental stressors -- namely plastic pollution and seawater flooding -- can increase the threats faced by plants in some of the planet's critical ecosystems. It showed that both stressors had some effects on the species tested, but being exposed to both microplastics and flooding together -- a threat likely to increase as a result of climate change and plastic use -- had a more pronounced impact on their resource allocation.
Published Dopamine physiology in the brain unveiled through cutting-edge brain engineering



Researchers have discovered a new correlation between neural signaling in the brain and dopamine signaling in the striatum. The human brain requires fast neural signal processing in a short period of less than a second. Dopamine is known to have the strongest effect on brain neural signals, but the research team's newly developed 'optical neural chip-based multiple brain signal monitoring technology' shows that changes in dopamine signals within the physiological range do not affect brain neural signal processing.
Published Precise package delivery in cells?



Researchers have developed new real-time microscopy technology and successfully observed the behavior of 'motor proteins', which may hold the key to unraveling the efficient material transport strategy of cells.
Published Research catalogs greenhouse gas emissions tied to energy use for interbasin water transfers



Much of the water in the West is transported across vast geographical areas by large infrastructure projects known as interbasin water transfers. Two of these projects in particular make up 85% of all energy-related greenhouse gas emissions associated with U.S. interbasin transfers -- one in Arizona and the other in California -- according to the new research.
Published Climate change may lead to shifts in vital Pacific Arctic fisheries



Commercially important marine fish and invertebrate species will likely shift northwards under a warmer climate, according to new research.
Published Sustainable catalysts: Crystal phase-controlled cobalt nanoparticles for hydrogenation



Controlling the crystal phase of cobalt nanoparticles leads to exceptional catalytic performance in hydrogenation processes, scientists report. Produced via an innovative hydrosilane-assisted synthesis method, these phase-controlled reusable nanoparticles enable the selective hydrogenation of various compounds under mild conditions without the use of harmful gases like ammonia. These efforts could lead to more sustainable and efficient catalytic processes across many industrial fields.
Published Engineering researchers crack the code to boost solar cell efficiency and durability



Photovoltaic (PV) technologies, which convert light into electricity, are increasingly applied worldwide to generate renewable energy. Researchers have now developed a molecular treatment that significantly enhances the efficiency and durability of perovskite solar cells. Their breakthrough will potentially accelerate the large-scale production of this clean energy.
Published Breakthrough in plant disease: New enzyme could lead to anti-bacterial pesticides



Scientists uncover a pivotal enzyme, XccOpgD, and its critical role in synthesizing C G16, a key compound used by Xanthomonas pathogens to enhance their virulence against plants. This breakthrough opens new avenues for developing targeted pesticides that combat plant diseases without harming beneficial organisms. Insights into XccOpgD's enzymatic mechanism and optimal conditions offer promising prospects for sustainable agriculture, bolstering crop resilience and global food security while minimizing environmental impact.
Published Electrical impedance tomography--extracellular voltage activation technique simplifies drug screening



Recently, researchers developed a non-invasive method combining electrical impedance tomography and extracellular voltage activation to evaluate drug effects on ion channels. The resulting printed circuit board sensor allows real-time monitoring of how newly developed drugs can affect ion flow in channels, providing a cost-effective and accurate alternative to traditional methods like patch-clamp techniques and paving the way toward more efficient and shorter preclinical testing in the drug discovery process.
Published Proteins as the key to precision medicine: Finding unknown effects of existing drugs



Fewer side effects, improved chances of healing: the goal of precision medicine is to provide patients with the most individualized treatment possible. This requires a precise understanding of what is happening at the cellular level. Researchers have now succeeded in mapping the interactions of 144 active substances with around 8,000 proteins. The results could help to identify previously unknown potential benefits of existing drugs.
Published Tipping risks from overshooting 1.5 °C can be minimized if warming is swiftly reversed



Current climate policies imply a high risk for tipping of critical Earth system elements, even if temperatures return to below 1.5 C of global warming after a period of overshoot. A new study indicates that this risk can be minimized if the warming is swiftly reversed. That is why reducing emissions in the current decade is crucial for the stability of the Earth systems functions, researchers write. They analyzed the tipping risks for four interconnected core climate tipping elements: the Greenland Ice Sheet, the West Antarctic Ice Sheet, the Atlantic Meridional Overturning Circulation (AMOC), and the Amazon Rainforest.
