Exposure to tiny air pollution particles may lead to reduced sperm production, suggests new research in mice to be presented Monday, March 25, at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.
Researchers from Tokyo Metropolitan University have shown that a newly engineered catalyst made of gold nanoparticles supported on a metal oxide framework shows breakdown of ammonia impurities in air, with excellent selectivity for conversion to nitrogen gas. Importantly, it is effective at room temperature, making it suitable for everyday air purification systems. The team successfully identified the mechanism behind this behavior, paving the way towards the design of other novel catalytic materials.
Fulfilling the world's growing energy needs summons images of oil pipelines, electric wires and truckloads of coal. But Michigan State University research shows a lot of energy moves nearly incognito, embedded in the products, and leaves its environmental footprint home.
When you flush the toilet, you probably don't think about the traces of the medicine and personal care products in your body that are winding up in sewage treatment plants, streams, rivers, lakes, bays and the ocean. But Rutgers scientists have found that bacteria in sewage treatment plants may be creating new contaminants that have not been evaluated for potential risks and may affect aquatic environments, according to a study in Environmental Toxicology and Chemistry.
Scientists in China have developed a process for converting plant waste from agriculture and timber harvesting into high-density aviation fuel. Their research, published March 21 in the journal Joule, may help reduce CO2 emissions from airplanes and rockets.
We all know that turning off lights and buying energy-efficient appliances affects our financial bottom line. Now, according to a new study by University of Wisconsin-Madison researchers, we know that saving energy also saves lives and even more money for consumers by alleviating the costs of adverse health effects attributed to air pollution.
Irrigation water's E. coli results can differ between labs, test types.
Amidst worldwide talks about 'Insectageddon': the extinction of 40 percent of the world's insects, according to a recent scientific review, a response was published in the open-access journal Rethinking Ecology. Its authors point out major flaws in the earlier study: query- and geographically biased summaries; mismatch between objectives and cited literature; and misuse of existing conservation data. Instead of serving as a wake-up call, those would rather compromise the credibility of conservation science, they warn.
With an estimated daily fuel demand of more than 5 million barrels per day, the global aviation sector is incredibly energy-intensive and almost entirely reliant on petroleum-based fuels. However, a new analysis by Berkeley Lab shows that sustainable plant-based bio-jet fuels could provide a competitive alternative to conventional fuels if current development and scale-up initiatives continue to push ahead successfully.
A team of four scientists from the US and the UK explain how differing climate model projections can be used collectively to reduce uncertainties in future climate change, in a paper published in the journal Nature Climate Change.
