An artificial pathway for turning carbon dioxide into useful products
Researchers have developed a synthetic pathway to 'fix' carbon dioxide -- converting it into organic compounds -- more quickly than can be achieved by plants. While the pathway has not yet been implemented in a living organism, the work to create an efficient carbon dioxide-fixation cycle represents an impressive technical feat, with applications including transplantation into living plants for faster, less energy-intensive carbon dioxide fixation.

Sensitivity of carbon cycle to tropical temperature variations has doubled, research shows
The tropical carbon cycle has become twice as sensitive to temperature variations over the past 50 years, new research has revealed. The research shows that a one degree rise in tropical temperature leads to around two billion extra tonnes of carbon being released per year into the atmosphere from tropical ecosystems, compared with the same tropical warming in the 1960s and 1970s.
