Published Scientists call for an update in environmental decision making that takes human rights into account
(via sciencedaily.com) Original source Researchers argue that to protect human wellbeing global decisions with the potential to impact the environment must be guided by our understanding of the inseparable connection between humans and nature. The article's authors are aiming to support fair and inclusive decision-making for a healthy ocean for people and planet.
Published DNA tech offers both data storage and computing functions
(via sciencedaily.com) Original source Researchers have demonstrated a technology capable of a suite of data storage and computing functions -- repeatedly storing, retrieving, computing, erasing or rewriting data -- that uses DNA rather than conventional electronics. Previous DNA data storage and computing technologies could complete some but not all of these tasks.
Published Catalyst for 'one-step' conversion of methane to methanol
(via sciencedaily.com) Original source Scientists have engineered a highly selective catalyst that can convert methane, a major component of natural gas, into methanol, an easily transportable liquid fuel, in a single, one-step reaction. This direct process for methane-to-methanol conversion runs at a temperature lower than required to make tea and exclusively produces methanol without additional byproducts.
Published Extraterrestrial chemistry with earthbound possibilities
(via sciencedaily.com) Original source Who are we? Why are we here? We are stardust, the result of chemistry occurring throughout vast clouds of interstellar gas and dust. To better understand how that chemistry could create prebiotic molecules, researchers investigated the role of low-energy electrons created as cosmic radiation traverses through ice particles. Their findings may also inform medical and environmental applications on our home planet.
Published First visualization of valence electrons reveals fundamental nature of chemical bonding
(via sciencedaily.com) Original source The distribution of outermost shell electrons, known as valence electrons, of organic molecules was observed for the first time. As the interactions between atoms are governed by the valence electrons, the findings shine light on the fundamental nature of chemical bonds, with implications for pharmacy and chemical engineering.
Published Quality control: Neatly arranging crystal growth to make fine thin films
(via sciencedaily.com) Original source Researchers have succeeded in forming metal-organic framework thin films on a substrate while controlling the growth direction of crystals so that they are arranged neatly without gaps. The resulting thin films of unprecedented high quality can be expected for use as optical sensors, optical elements, and transparent gas adsorption sheets.
Published Mobile species are 'glue' which connect different habitats together
(via sciencedaily.com) Original source A groundbreaking study conducted across 30 field sites in the southwest UK has revealed the importance of incorporating varied habitats into the landscape at large.
Published Molecular wires with a twist
(via sciencedaily.com) Original source Researchers have developed molecular wires with periodic twists. By controlling the lengths of regions between twists, the electrical conductivity of individual polymer chains can be enhanced. This work may lead to novel organic electronics or single-molecule wires.
Published 'Molecular compass' points way to reduction of animal testing
(via sciencedaily.com) Original source Machine learning models have become increasingly popular for risk assessment of chemical compounds. However, they are often considered 'black boxes' due to their lack of transparency. To increase confidence in these models, researchers proposed carefully identifying the areas of chemical space where these models are weak. They developed an innovative software tool for this purpose, and the results of this research approach have just been published.
Published A new reaction to enhance aromatic ketone use in chemical synthesis
(via sciencedaily.com) Original source Researchers develop a one pot process to transform aromatic ketones to esters, offering advancements in pharmaceutical synthesis and materials science.
Published Investigating the interplay of folding and aggregation in supramolecular polymer systems
(via sciencedaily.com) Original source Scientists have developed photoresponsive supramolecular polymers that can undergo both intrachain folding and interchain aggregation.
Published Forest loss intensifies climate change by increasing temperatures and cloud level, which leads to decrease of water
(via sciencedaily.com) Original source Researchers report that deforestation during the last two decades induced a higher warming and cloud level rise than that caused by climate change, which threatens biodiversity and water supply in African montane forests.
Published It's a rave: Underground acoustics amplify soil health
(via sciencedaily.com) Original source Barely audible to human ears, healthy soils produce a cacophony of sounds in many forms -- a bit like an underground rave concert of bubble pops and clicks. Special recordings made by ecologists show this chaotic mixture of soundscapes can be a measure of the diversity of tiny living animals in the soil, which create sounds as they move and interact with their environment.
Published Research provides a roadmap for improving electrochemical performance
(via sciencedaily.com) Original source A study expands understanding on how electrons move through the conductive parts of complex fluids found in electrochemical devices such as batteries. This work can help overcome existing knowledge gaps for engineers seeking to improve the performance of these devices.
Published As human activities expand in Antarctica, scientists identify crucial conservation sites
(via sciencedaily.com) Original source Establishing Key Biodiversity Areas in the Southern Ocean will be vital for safeguarding the ecosystem from the impact of human activities, researchers say.
Published Nearly 25% of European landscape could be rewilded, researchers say
(via sciencedaily.com) Original source Europe's abandoned farmlands could find new life through rewilding, a movement to restore ravaged landscapes to their wilderness before human intervention. A quarter of the European continent, 117 million hectares, is primed with rewilding opportunities, researchers report.
Published Enhancing electron transfer for highly efficient upconversion OLEDs
(via sciencedaily.com) Original source Electron transfer is enhanced by minimal energetic driving force at the organic-semiconductor interface in upconversion (UC) organic light emitting diodes (OLEDs), resulting in efficient blue UC-OLEDs with low extremely turn-on voltage, scientists show. Their findings deepen the understanding of electron transfer mechanisms in organic optoelectronic devices and can lead to the development of efficient new optoelectronics without energy loss.
Published Warming waters and nutrient overload: A dangerous combination threatening our rivers and lakes
(via sciencedaily.com) Original source New international research found that food webs are becoming less complex in warmer, nutrient-rich waters.
Published Lake Erie walleye growth is driven by parents' size, experience
(via sciencedaily.com) Original source Parent size and the conditions in which actively spawning adults lived are the most influential factors affecting growth of Lake Erie walleye, a new study has found.
