But the carbon fixing champs are not plants, but soil bacteria. Some bacterial enzymes carry out a key step in carbon fixation 20 times faster than plant enzymes do, and figuring out how they do this could help scientists develop forms of artificial photosynthesis to convert the greenhouse gas into fuels, fertilizers, antibiotics and other …
The team showed for the first time that these deep-sea, plastic loving bacteria make up only 1% of the total bacterial community. Reporting their findings in the journal Environmental Pollution, the team found that these bacteria only stick to plastic and not the non-plastic control of stone. The research highlights these bacteria may be able …
Now, after the United Nations’ historic decision to adopt a global treaty to end plastic pollution earlier this year, governmental negotiations on the agreement are set to begin on May 30th. These will foster intense debates on what kind of measures will be needed to end the pollution of the air, soils, rivers and oceans …
Despite being amongst the world’s most destructive extreme weather events, tropical cyclones are relatively rare. In a given year, only around 80-100 tropical cyclones form globally, most of which never make landfall. In addition, accurate global historical records are scarce, making it hard to predict where they will occur and what actions Governments should take …
The suitcase-sized device, which requires less power to operate than a cell phone charger, can also be driven by a small, portable solar panel, which can be purchased online for around $50. It automatically generates drinking water that exceeds World Health Organization quality standards. The technology is packaged into a user-friendly device that runs with …
The work led by UAF Geophysical Institute associate research professor Gunther Kletetschka adds to a growing body of research about water at the moon’s north and south poles. Finding water is key to NASA’s Artemis project, the planned long-term human presence on the moon. NASA plans to send humans back to the moon this decade. …
This discovery, published today in Nature, could help solve one of the world’s most pressing environmental problems: what to do with the billions of tons of plastic waste piling up in landfills and polluting our natural lands and water. The enzyme has the potential to supercharge recycling on a large scale that would allow major …
All six species are smaller than a British 1p coin — around 15mm long — when fully grown. Adult males of the tiniest of these species, named Craugastor candelariensis, grow to only 13mm. The newly discovered species are known as ‘direct-developing’ frogs: rather than hatching from eggs into tadpoles like most frogs, they emerge …
The study, published April 26 in the journal Scientific Reports, is the first to connect microplastics in the ocean with land-based pathogens. It found that microplastics can make it easier for disease-causing pathogens to concentrate in plastic-contaminated areas of the ocean. The pathogens studied — Toxoplasma gondii, Cryptosporidium (Crypto) and Giardia — can infect …
