Many technologies developed for capturing carbon dioxide emissions have a limitation – in order to reclaim the captured CO2, a considerable amount of energy is needed. Now, however, scientists have developed a new carbon-capture material that requires far less energy in order to give up its payload.

An engine powered by frozen carbon dioxide holds the potential to use the natural resources found on Mars to supply the on-going energy requirements of future long-term missions or attempts at colonization of the planet.

Carbon sequestration may not, according to researchers at MIT, be the panacea that some had hoped. A recent study has found that far less carbon dioxide than the ideal prediction of 90 percent may be turned into rock when sequestered.

As one of our most relied upon construction materials, concrete makes a significant contribution to our overall carbon emissions. By altering the quantities of materials used in this process, scientists have uncovered a method of cement mixing that could reduce these emissions by more than half.

To help future explorers of the Red Planet get enough oxygen for life support and powering spacecraft, NASA has included MIT’s MOXIE experiment on the Mars 2020 mission to study how to make oxygen out of the Martian atmosphere.

Researchers at Princeton University have converted CO<sub>2</sub> into water and formic acid by using an electrochemical cell powered by a commercially available solar panel.

In a move that could help address our insatiable thirst for fuel while at the same time help cut CO2 emissions, scientists with the SOLAR-JET project have shown that concentrated sunlight can be used to convert carbon dioxide into kerosene, which can then be used as jet fuel.

Carbon capture and storage has long been considered a costly but necessary step in reducing emissions and protecting our environment. New research by Sintef scientists has found that refrigeration technology may reduce cost by up to 30 percent, increasing the potential for faster implementation.

A link has been made between the abnormal breathing patterns experienced while sleeping at altitudes higher than 2,500 m (8,200 ft) and the symptoms of altitude sickness, particularly headaches. The finding could lead to potential treatments to combat altitude sickness.

A team of researchers may have found new evidence to shed light on the cause of the most devastating mass extinction in the history of our planet. The event, estimated to have taken place around 252 million years ago, was responsible for the extinction of roughly 90 percent of all life on Earth.
