Transforming sewer gas into clean hydrogen fuel

Scientists have found a new chemical process to turn a stinky, toxic gas into a clean-burning fuel. The process, detailed recently in the American Chemical Society journal ACS Sustainable Chemical Engineering, turns hydrogen sulfide – more commonly called “sewer gas” – into hydrogen fuel. Hydrogen sulfide is emitted from manure piles and sewer pipes and is […]

Fact-checking works across the globe to correct misinformation

Fact-checking works to reduce false beliefs across the globe, according to a new study conducted in four countries. Researchers found that fact-checking worked with little variation in Argentina, Nigeria, South Africa and the U.K., and the positive effects were still detectable two weeks later. Even more encouraging, there was no evidence of a “backfire” effect […]

Stinkweed could make a cleaner bio-jet fuel

A common farm weed could make a “greener” jet fuel with fewer production-related environmental impacts than other biofuels, a new study indicates. Growing the weed, pennycress – often called stinkweed – as a crop requires less fertilizer and fewer pesticides than other plants that can be used to make renewable jet fuel, according to the […]

15,000-year-old viruses discovered in Tibetan glacier ice

Scientists who study glacier ice have found viruses nearly 15,000 years old in two ice samples taken from the Tibetan Plateau in China. Most of those viruses, which survived because they had remained frozen, are unlike any viruses that have been cataloged to date. The findings, published today in the journal Microbiome, could help scientists understand how […]

Mountaintop glacier ice disappearing in tropics around the world

Mountaintop glacier ice in the tropics of all four hemispheres covers significantly less area — in one case as much as 93% less — than it did just 50 years ago, a new study has found. The study, published online recently in the journal Global and Planetary Change, found that a glacier near Puncak Jaya, in […]
