  • Study quantifies potential for water reuse in permian basin oil production
    on September 6, 2017 at 9:01 pm

    Hydraulic fracturing has once again made the Permian Basin one of the richest oil fields in the world. But the improved reserves come with some serious water management issues. Drilling for oil uses water upfront, and brings up large volumes of water that need to be managed. The study found that recycling the water produced during operations at other hydraulic fracturing sites could help reduce potential problems associated with the technology. […]

  • High-tech electronics made from autumn leaves
    on August 29, 2017 at 3:38 pm

    Northern China's roadsides are peppered with deciduous phoenix trees, producing an abundance of fallen leaves in autumn. These leaves are generally burned in the colder season, exacerbating the country's air pollution problem. Investigators in Shandong, China, recently discovered a new method to convert this organic waste matter into a porous carbon material that can be used to produce high-tech electronics. […]

  • Arsenic risk in Pakistan much greater than expected
    on August 23, 2017 at 6:54 pm

    Arsenic-contaminated groundwater may threaten the health of 50 to 60 million people in Pakistan. This is shown by a study in which data from 1,200 groundwater samples was analyzed and combined with hydrological parameters to generate a hazard map. This reveals for the first time the full extent of the risks to which the population of Pakistan is exposed. In addition, there is growing evidence that natural arsenic levels are increased by extensive irrigation. […]
