Do volcanoes add more carbon than they take away?
In a new study published in the Journal of Geophysical Research: Biogeosciences, Zhong and colleagues discovered that a volcano in northeast China emits a small net amount of carbon each year. Over geological timescales, that could have a significant.....»»
Novel carbon nanotube yarns can generate electricity from waste heat
In line with global efforts towards sustainability, the development of energy harvesting technologies has become a top research priority. Although renewable energy sources like wind and solar power have recently taken the spotlight, waste heat also s.....»»
Study shows transgenic expression of rubisco factors increases photosynthesis and chilling tolerance in maize
Maize is one of the world's most widely grown crops and is essential to global food security. But like other plants, its growth and productivity can be limited by the slow activity of Rubisco, the enzyme responsible for carbon assimilation during pho.....»»
New research shows soil microorganisms could produce additional greenhouse gas emissions from thawing permafrost
As the planet has warmed, scientists have long been concerned about the potential for harmful greenhouse gases to seep out of thawing Arctic permafrost. Recent estimates suggest that by 2100 the amount of carbon dioxide and methane released from thes.....»»
Study introduces a cleaner way to produce ammonia at room temperature and pressure
Ammonia is the starting point for the fertilizers that have secured the world's food supply for the last century. It's also a main component of cleaning products, and is even considered as a future carbon-free replacement for fossil fuels in vehicles.....»»
Tropical forest resilience to seasonal drought linked to nutrient availability
Tropical forests are highly productive ecosystems, accounting for nearly half of the global forest carbon sink. If tropical forests can no longer remove carbon dioxide from the atmosphere, the effects of climate change may become even more severe......»»
Q&A: Plastic waste is a global problem, but carbon recycling can help
Heavy industries such as aviation and chemical manufacturing contribute to about 20% of overall U.S. greenhouse gas emissions and will continue to depend on fossil fuels......»»
Buried kelp: Seaweed carried to the deep sea stores more carbon than we thought
Deep in the ocean lies the world's largest active carbon reservoir, which plays a pivotal role in buffering our planet's climate. Of the roughly 10 billion metric tons of carbon dioxide we emit each year, about 3 billion metric tons are taken up and.....»»
Toyota, Mazda, Subaru debut high-tech engines in fight against carbon
Toyota and Japanese car-making allies Mazda and Subaru are doubling down on a new generation of internal combustion as a weapon in the fight against carbon emissions, even as the auto industry enters the age of EVs......»»
Scientists say they can make zero-emission cement
Researchers on Wednesday said they were a step closer to solving one of the trickiest problems in tackling climate change—how to keep making cement despite its enormous carbon footprint......»»
New study offers a cleaner path for controlling water, transforming greenhouse gases
Scientists looking to convert carbon dioxide into clean fuels and useful chemicals often make hydrogen gas and carbonates as unwanted byproducts. A new paper from the UChicago Pritzker School of Molecular Engineering has found a cleaner path......»»
Carbon dioxide, the main culprit of global warming, reborn as an antioxidant substance
A research team led by Dr. Lee Soo Youn at the Gwangju Clean Energy Research Center of the Korea Institute of Energy Research (KIER) has successfully converted carbon dioxide, the main culprit of global warming, into carotenoids, which possess antiox.....»»
Saltmarshes do store carbon, but their climate impact may have been overestimated
Saltmarshes, or tidal marshes, are able to capture carbon dioxide from the atmosphere and lock it away at a far higher rate than even forests on land. This has lead to them being championed as a nature-based solution to climate change. However, our r.....»»
Scientists report on a new approach for deducing proton radii from charge-changing reactions
A study systematically measured the charge-changing reaction cross section of 24 light nuclei on carbon and hydrogen targets at the GSI Helmholtz Centre for Heavy Ion Research in Germany......»»
The value of failure in conservation programs
Conservation programs need—and often incentivize—community involvement. For example, a program in Zanzibar, Tanzania, asked communities to protect their village forests in exchange for access to the carbon credits market. Despite community enthus.....»»
Seaweed forests are an overlooked component of oceanic carbon storage, study finds
A new study by an international team of researchers has revealed seaweed forests are significant contributors to ocean carbon storage......»»
Scientists develop new battery-free lactic acid sensor
Scientists at Bath, have introduced a breakthrough carbon-based sensor for detecting lactic acid levels in saliva—avoiding the need for an electrical power source......»»
New insights into the degradation dynamics of organic material in the seafloor
The long-term deposition of organic material in sediments on the ocean floor is a key process in the global carbon cycle. The question of whether, from a chemical perspective, the deposited material is more similar to marine algae or the microorganis.....»»
A metal-free organic framework for electrocatalytic production of ethylene from carbon dioxide
Use of the greenhouse gas CO2 as a chemical raw material would not only reduce emissions, but also the consumption of fossil feedstocks. A novel metal-free organic framework could make it possible to electrocatalytically produce ethylene, a primary c.....»»
New catalyst transforms carbon dioxide from industrial emissions into commonly used chemicals
A low-cost, tin-based catalyst can selectively convert carbon dioxide to three widely produced chemicals—ethanol, acetic acid and formic acid......»»
A review of the applications of mercury stable isotopes for tracing volcanism in geologic events
Mercury is a toxic heavy metal that can exist stably as a gas, with high volatility and global distribution in the atmosphere. Volcanoes represent a primary natural source of Hg in the atmosphere, with significant effects on Hg cycles on both global.....»»
