Published Scientific ocean drilling discovers dynamic carbon cycling in the ultra-deep-water Japan Trench
(via sciencedaily.com) Original source Hadal trenches, with their deepest locations situated in the so-called hadal zone, the deepest parts of the ocean in water depth >6km, are the least-explored environment on Earth, linking the Earth's surface and its deeper interior. An international team conducting deep-subsurface sampling in a hadal trench at high spatial resolution has revealed exciting insights on the carbon cycling in the trench sediment.
Published Researchers charting a sustainable course in oceanic carbon capture
(via sciencedaily.com) Original source As researchers around the world race against time to develop new strategies and technologies to fight climate change, a team of scientists is exploring one possible way to directly reduce the amount of carbon dioxide in the environment: Negative emissions technologies (NETs).
Published Improving transistor performance through perovskite-cation incorporation
(via sciencedaily.com) A team advances transistor performance through perovskite-cation incorporation.
Published Floating sea farms: A solution to feed the world and ensure fresh water by 2050
(via sciencedaily.com) Original source The sun and the sea -- both abundant and free -- are being harnessed in a unique project to create vertical sea farms floating on the ocean that can produce fresh water for drinking and agriculture.
Published Scientists find evidence of sea star species hybridization
(via sciencedaily.com) A new study presents genomic evidence of hybridization between two closely related species of sea stars -- Asterias rubens, the common starfish, and Asterias forbesi, known as Forbes' sea star.
Published Study reveals human destruction of global floodplains
(via sciencedaily.com) Original source A hydrologist's study provides a global estimate of human destruction of natural floodplains. The study can help guide future development in a way that can restore and conserve vital floodplain habitats that are critical to wildlife, water quality and reducing flood risk for people.
Published Bacteria generate electricity from wastewater
(via sciencedaily.com) In a breakthrough for the field of bioelectronics, researchers have enhanced the ability of E. coli bacteria to generate electricity. The innovative approach only offers a sustainable solution for organic waste processing while outperforming previous state-of-the-art technologies, opening new horizons for versatile microbial electricity production.
Published Benchtop NMR spectroscopy can accurately analyse pyrolysis oils
(via sciencedaily.com) A team of researchers has demonstrated that benchtop spectrometers are capable of analyzing pyrolysis bio-oils just as well as far more expensive, high-field spectrometers.
Published New study highlights feasibility and optimization of ammonia-based power generation for carbon neutrality
(via sciencedaily.com) A research team has evaluated the feasibility of ammonia-based power generation through techno-economic and carbon footprint analyses.
Published Invasive alien species play key role in 60% of global plant and animal extinctions
(via sciencedaily.com) A new report presents major findings on the gravity of impacts from invasive alien species on our planet.
Published New bio-based glues form adhesive bonds that grow stronger in water
(via sciencedaily.com) Patent-pending adhesive formulations developed from fully sustainable, bio-based components establish bonds that grow stronger when underwater or exposed to wet conditions.
Published A finer picture of global migration reveals complex patterns
(via sciencedaily.com) Original source New research shows that socio-economic factors play a larger role in migration than climate.
Published Bursting air bubbles may play a key role in how glacier ice melts
(via sciencedaily.com) Original source New research has uncovered a possible clue as to why glaciers that terminate at the sea are retreating at unprecedented rates: the bursting of tiny, pressurized bubbles in underwater ice.
Published Stability inspection for West Antarctica shows: marine ice sheet is not destabilized yet, but possibly on a path to tipping
(via sciencedaily.com) Original source Antarctica's vast ice masses seem far away, yet they store enough water to raise global sea levels by several meters. A team of experts has now provided the first systematic stability inspection of the ice sheet's current state. Their diagnosis: While they found no indication of irreversible, self-reinforcing retreat of the ice sheet in West Antarctica yet, global warming to date could already be enough to trigger the slow but certain loss of ice over the next hundreds to thousands of years.
Published Extending the playing field for organosulfurs: a new way to synthesize sulfinate esters
(via sciencedaily.com) Sulfinate esters, a type of organosulfur compounds, are typically synthesized using thiols. However, these substances are difficult to work with due to their unpleasant smell and oxidizability in air. Now, a research team has found a way to produce sulfinate esters through the direct oxidation of thioesters, which are easily accessible and stable. Their findings will help expand the field of organosulfur chemistry and hopefully lead to new applications in pharmaceuticals.
Published Ag tech can cut billions of tons of greenhouse gas emissions
(via sciencedaily.com) Original source As the Earth's human population grows, greenhouse gas emissions from the world's food system are on track to expand. A new study demonstrates that state-of-the-art agricultural technology and management can not only reduce that growth, but eliminate it altogether by generating net negative emissions -- reducing more greenhouse gas than food systems add.
Published Chemists devise a method for C-H activation of alcohols
(via sciencedaily.com) Chemists have extended a powerful molecule-building method -- called C-H activation -- to the broad class of chemicals known as alcohols.
Published Researchers develop highly efficient and stable photoelectrode for water splitting using organic semiconductors
(via sciencedaily.com) A recent study has unveiled a significant breakthrough in photoelectrode development.
Published Fossil spines reveal deep sea's past
(via sciencedaily.com) Original source Right at the bottom of the deep sea, the first very simple forms of life on earth probably emerged a long time ago. Today, the deep sea is known for its bizarre fauna. Intensive research is being conducted into how the number of species living on the sea floor have changed in the meantime. Some theories say that the ecosystems of the deep sea have emerged again and again after multiple mass extinctions and oceanic upheavals. Today's life in the deep sea would thus be comparatively young in the history of the Earth. But there is increasing evidence that parts of this world are much older than previously thought.
Published Electrifying heavy-duty vehicles could reduce environmental inequalities
(via sciencedaily.com) If the region surrounding Chicago -- North America's largest freight hub -- shifted just 30% of its current on-road heavy-duty vehicles to electric versions, it would substantially reduce pollution and save hundreds of lives per year, with the benefits largely concentrated in disadvantaged communities, according to a new study. The study authors highlight that neighborhoods with predominantly Black, Hispanic and Latinx residents would benefit the most -- potentially reducing disproportionate pollution and health burdens in historically marginalized areas.
