Using Reishi mushrooms to filter methane out of the atmosphere

Methane and carbon dioxide are two greenhouse gases that are rapidly accumulating in Earth’s atmosphere. A molecule of methane can absorb 28 times more infrared radiation and heat than a single molecule of carbon dioxide. Due to this effect, these gases are major concerns to scientists who study human-linked climate change on Earth, and their […]

Made of layered sodium titanate, the randomly oriented nanofibers increase the efficacy of cobalt-II […]

Maya imported zeolite and quartz to filter drinking water — ScienceDaily

Ancient Maya in the once-bustling city of Tikal built sophisticated water filters using natural materials they imported from miles away, according to the University of Cincinnati. UC researchers discovered evidence of a filter system at the Corriental reservoir, an important source of drinking water for the ancient Maya in what is now northern Guatemala. A […]
