Portal to the past: Geologist identifies metamorphic rock as a crucial feature of the ancient Earth"s carbon cycle
If Earth's history were a calendar year, humans would not appear until the last few minutes before midnight on Dec. 31. During the Proterozoic Eon—2.5 billion years to 543 million years ago—the sun was still a young star, much dimmer than today,.....»»
Artificial intelligence: A double-edged sword for the environment?
As AI technology progresses, the energy demands of training complex AI models have surged, raising widespread concerns about associated carbon emissions. This rapid growth is fueled by global demand across industries and academia, leading to exponent.....»»
Rubber plantations increase leaching of dissolved organic carbon in soil, study finds
Rubber planting brings huge economic benefits, but large-scale rubber plantations have a great impact on the ecological environment, especially in terms of the soil's physical and chemical properties......»»
New research estimates carbon emissions from 22 million stream reaches across the US
Using a sophisticated new modeling approach, researchers at the University of Massachusetts Amherst have estimated carbon dioxide emissions from inland waters to 22 million U.S. lakes, rivers and reservoirs. It marks the first time this approach has.....»»
Study examines effects of Atlantic circulation on the Amazon rainforest
The Amazon region is a global hotspot of biodiversity and plays a key role in the climate system because of its ability to store large amounts of carbon and its influence on the global water cycle. The rain forest is threatened, however, by climate c.....»»
Cobalt-copper tandem system offers sustainable approach for converting carbon dioxide to ethanol
The continuing release of carbon dioxide into the atmosphere is a major driver of global warming and climate change with increased extreme weather events. Researchers at Johannes Gutenberg University Mainz (JGU) have now presented a method for effect.....»»
Revealing the superconducting limit of twisted bilayer graphene
Graphene is a simple material containing only a single layer of carbon atoms, but when two sheets of it are stacked together and offset at a slight angle, this twisted bilayer material produces numerous intriguing effects, notably superconductivity......»»
Experiments find coral reefs can survive some climate change—with help
If carbon emissions are curbed and local stressors are addressed, coral reefs have the potential to persist and adapt over time. That's according to a study published in the Proceedings of the National Academy of Sciences by researchers at the Univer.....»»
Mangrove degradation threatens carbon storage in China"s Pearl Bay
Carbon sinks are important in the fight against climate change as they draw down atmospheric carbon dioxide levels by storing organic carbon in the oceans and soil, for example. Within tropical and subtropical intertidal locations, wetland plant comm.....»»

Deep sea rocks suggest oxygen can be made without photosynthesis, deepening the mystery of life
Oxygen, the molecule that supports intelligent life as we know it, is largely made by plants. Whether underwater or on land, they do this by photosynthesizing carbon dioxide. However, a recent study demonstrates that oxygen may be produced without th.....»»
Scientists investigate contrail formation to reduce climate impact
From the development of new materials that make airplanes lighter to the exploration of alternative fuels, the aviation industry is making strides toward reducing its carbon footprint......»»
New method successfully recycles carbon fiber composite into reusable materials
USC researchers have developed a new process to upcycle the composite materials appearing in automobile panels and light rail vehicles, addressing a current environmental challenge in the transportation and energy sectors. The study recently appeared.....»»
Researchers observe stick-slip phenomenon in carbon nanotube fibers
The shapes of simple polyatomic molecules such as carbon dioxide and methane are characterized by a specific symmetry depending on the manner of linking of the atoms. Nano- to micrometer-sized particles that mimic the shapes of such polyatomic molecu.....»»
Global fleet of undersea robots reveals the phytoplankton hidden beneath the ocean"s surface
Phytoplankton—microscopic plant-like organisms—are the foundation of the marine food web, sustaining everything from tiny fish to multi-ton whales while also playing a critical role in removing carbon dioxide from the atmosphere......»»
Precise layering in catalysts offers an improved way for building sustainable chemicals
Motivated to turn greenhouse gases like carbon dioxide into high value chemicals like methanol, EPFL chemical engineers have developed a new method to make catalysts. Catalysts are major tools in the chemical industry and are largely made to make pet.....»»
Volcanic "cryptic carbon" emissions may be a hidden driver of Earth"s past climate
An international team of geoscientists led by a volcanologist at Rutgers University-New Brunswick has discovered that, contrary to present scientific understanding, ancient volcanoes continued to spew carbon dioxide into the atmosphere from deep with.....»»
The M4 Mac mini is Apple’s first carbon neutral Mac
Apple’s second day of new Mac announcements brought the redesigned and radically smaller M4 Mac mini. But the redesign isn’t all about aesthetics. The new Mac mini is also now Apple’s first carbon neutral Mac. more….....»»
Intensive fishing on the seabed increases the release of carbon, researchers find
Flatfish and shrimp are caught in the North Sea by using trawls that are dragged across the seabed. This releases carbon into the water and carbon dioxide (CO2) into the atmosphere, as shown by the latest research at the Helmholtz-Zentrum Hereon......»»
Newly discovered cyanobacteria could help sequester carbon from oceans and factories
An international coalition of researchers from the United States and Italy has discovered a novel strain of cyanobacteria, or algae, isolated from volcanic ocean vents that is especially adept at growing rapidly in the presence of CO2 and readily si.....»»
