Molecules containing large chains of carbon and hydrogen -- the building blocks of all life on Earth -- have been the targets of missions to Mars from Viking to the present day. While these molecules have previously been found in meteorites from Mars, scientists have disagreed about how this organic ...

(Phys.org) -- Whether used in telescopes or optoelectronic communications, infrared detectors must be continuously cooled to avoid being overwhelmed by stray thermal radiation. Now, a team of researchers from Peking University, the Chinese Academy of Sciences, and Duke University (USA) is harnessing the remarkable properties of single-walled carbon nanotubes (SWNTs) ...

Seagrasses are a vital part of the solution to climate change and, per unit area, seagrass meadows can store up to twice as much carbon as the world's temperate and tropical forests.

(Phys.org) -- An electron’s spin is separate from its motion, and is suitable for use in both highly-precise magnetic sensing as well as a qubit in quantum computing. Recently, scientists at the University of Konstanz in Germany have theoretically investigated the coupling of electron spin in carbon nanotube quantum dots, ...

Scientists from the Woods Hole Oceanographic Institution (WHOI) have conducted a new study to measure levels of carbon at various depths in the Arctic Ocean. The study, recently published in the journal Biogeosciences, provides data that will help researchers better understand the Arctic Ocean’s carbon cycle—the pathway through which carbon ...

Scientists have conducted a new study to measure levels of carbon at various depths in the Arctic Ocean. The study provides data that will help researchers better understand the Arctic Ocean's carbon cycle -- the pathway through which carbon enters and is used by the marine ecosystem.

The amount of carbon stored in seagrass beds could be as much as 19.9 billion metric tons, researchers say.

Scientists have discovered a chemical reaction that not only eats up the greenhouse gas carbon dioxide, it creates some useful compounds to boot.

(Phys.org) -- A materials scientist at Michigan Technological University has discovered a chemical reaction that not only eats up the greenhouse gas carbon dioxide, it also creates something useful. And, by the way, it releases energy.

(Phys.org) -- The term ethylene (ethene) generally brings to mind polyethylene plastics, not fruit. However, ethylene is more than just a feedstock for chemical industry, it is also the smallest plant hormone, and it controls physiological processes, such as the ripening of fruit, seed germination, and the blooming and wilting ...

(Phys.org) -- For the first time, scientists have direct evidence that high-pressure carbon dioxide or CO2 migrates into the clay montmorillonite causing it to expand, according to scientists at Pacific Northwest National Laboratory. Montmorillonite is found in the rocks used to cap carbon sequestration sites, and scientists previously thought that ...

The University of California, Davis has conducted an innovative study on the effects of human tree usage on climate change. The findings offer a greater understanding of the intricate effects of deforestation on the global climate from greenhouse gas emissions, specifically focusing on carbon emissions. This study, published by the advance ...
