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......»»
COP29: AI can help develop climate-resistant crops for Africa—but it shouldn"t be left in the hands of corporates
How we use land and feed a growing global population, and the burden we place on natural habitats in pursuit of nutrition, will again take center stage at the annual global climate change conference, COP29, in November......»»
New process enhances thermoplastic blends with polylactic acid
Bio-based thermoplastics are produced from renewable organic materials and can be recycled after use. Their resilience can be improved by blending bio-based thermoplastics with other thermoplastics. However, the interface between the materials in the.....»»
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.....»»
Saturday Citations: On chimpanzee playwrights; the nature of dark energy; deep-diving Antarctic seals
This week, researchers reported the world's second-tiniest toad, winning the silver in the Brachycephalus contest. Chemists at UCLA disproved a 100-year-old organic chemistry rule. And researchers in Kenya report that elephants don't like bees, which.....»»
Dora Richardson Took Her Research Underground to Develop Lifesaving Tamoxifen
When chemist Dora Richardson’s employer decided to terminate the breast cancer research on the drug Tamoxifen in the early 1970s, she and her colleagues continued the work in secret......»»

Chiral molecular self-assemblies that absorb light boost singlet fission process, research demonstrates
In organic molecules, an exciton is a particle bound pair of an electron (negative charge) and its hole (positive charge). They are held together by Coulombic attraction and can move within molecular assemblies. Singlet fission (SF) is a process wher.....»»
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......»»
