Researchers propose a novel approach to reduce carbon emissions in cement manufacturing by leveraging iron naturally present in cement raw materials. The method enables the co-thermal conversion of CaCO₃ with CH₄ under a methane atmosphere, resulting in high-value syngas as a byproduct and significantly reducing carbon footprint.
Researchers at Nagoya University found that Japan's concrete structures, including buildings and infrastructure, absorb around 14% of the CO2 emissions generated during cement production. This process, known as carbonation, enables concrete to function as a carbon sink, even though it absorbs less CO2 than forests.
Hungarian researchers have identified unique bacterial communities in thermal waters that may help unravel the development of stromatolites, one of Earth's oldest rock formations. The findings provide valuable insights into biological and geological processes occurring in extreme environments today.
Borealis Mud Volcano provides a hard substrate for various species like anemones and octocoral colonies, sustaining local fish populations. The volcano's carbonates also offer shelter and feeding opportunities.
A recent study suggests that fizzy water may help with weight loss by increasing glucose uptake and metabolism. However, the effects are minimal and should not be relied upon as a sole means of shedding pounds. Regular physical activity and a healthy diet remain essential components of sustainable weight management.
A research team at Peking University reconstructed ocean acidification during the Palaeocene-Eocene Thermal Maximum, a major carbon release event 56 million years ago. The study's findings stress the urgency of addressing human-driven CO2 emissions to protect marine ecosystems, particularly in vulnerable regions like the Arctic.

Research finds that cold and carbonation reduce thirst more effectively than room temperature, with astringency, sweetness, or mild acidification having no effect. This knowledge could help guide sensory approaches to improve hydration in elderly, soldiers, and athletes at risk for dehydration.
A study published in Gastroenterology found that carbonation can trick the brain into perceiving artificially sweetened drinks as just as sweet as regular ones. This effect may facilitate weight loss by making low-calorie drinks more palatable, but it also increases sugar and food consumption.
Research from Monell Center reveals that carbonation's bite comes from the conversion of free carbon dioxide into carbonic acid in the mouth. Bubbles enhance this sensation through stimulation of the sense of touch.
