Researchers in Brazil find that high levels of heavy metals and particulate matter suspended in the atmosphere restrict the growth of tipuana trees, which are ubiquitous in São Paulo, the largest Brazilian city.
Ivan Nekhaev, a postdoc at St. Petersburg University, studied snails of the genus Boreocingula -- tiny gastropods as small as half a centimeter -- and first discovered that Arctic micromolluscs can show signs of pseudohermaphroditism. Boreocingula martyni adult females grow underdeveloped male genital organs.
A seemingly counterintuitive approach -- converting one greenhouse gas into another -- holds promise for returning the atmosphere to pre-industrial concentrations of methane, a powerful driver of global warming.
Could the health benefits and reduced costs to healthcare systems be enough to justify subsidizing charging infrastructure to allow society to switch from the internal combustion engine to electric vehicles faster than current trends predict?
A survey of plastic pollution on Australia's Cocos (Keeling) Islands has revealed the territory's beaches are littered with an estimated 414 million pieces of plastic debris. The study led by IMAS researcher Dr. Jennifer Lavers and published in the journal Scientific Reports estimated beaches on the Indian Ocean islands are littered with 238 tonnes of plastic, including 977,000 shoes and 373,000 toothbrushes.
New analysis by the UK Trade Policy Observatory is warning of a significant weakening of enforcement arrangements covering the approval of pesticides as part of legislative changes carried out under the EU Withdrawal Act.
The ubiquitous plastic bag is handy for transporting groceries and other items home from the store. However, this convenience takes a toll on the environment, with plastic debris littering land and waterways. Manufacturers offer biodegradable or compostable plastic bags, but in many cases, these claims have not been tested in natural environments. Now, researchers report in ACS' Environmental Science & Technology that the bags do not degrade in some environments any faster than regular polyethylene.
E-waste recycling is far below what it should be to reduce its impact on the environment and human health simply because it is not economically feasible. Researchers from Japan are working on a way to change that using pulsed power technology.
Scientists recycle phosphorus by combining dairy and water treatment leftovers.
A team of scientists has created a bowl-shaped electrode with 'hot edges' which can efficiently convert CO2 from gas into carbon based fuels and chemicals, helping combat the climate change threat posed by atmospheric carbon dioxide.
