    on February 9, 2018 at 10:07 pm

    With two billion people worldwide lacking access to clean and safe drinking water, new research may offer a breakthrough solution. Metal-organic frameworks (MOFs), a next-generation material with the largest internal surface area of any known substance, can be used to capture, store and release chemical compounds -- in this case, the salt and ions in sea water. […]

  • Small gold mines in Senegal create high mercury contamination
    on February 9, 2018 at 3:06 pm

    A new study has found high levels of mercury and methylmercury in soils, sediments and rivers near artisanal gold mines in Senegal. Nearly every sample collected from four mining villages contained mercury levels at least ten times higher than World Health Organization and U.S. Environmental Protection Agency standards. […]

    Mining on the ocean floor could do irreversible damage to deep-sea ecosystems, says a new study of seabed mining proposals around the world. […]

  • Using data mining to make sense of climate change
    on January 18, 2018 at 9:24 pm

    Experts have developed a new way of mining data from climate data sets that is more self-contained than traditional tools. The methodology brings out commonalities of data sets without as much expertise from the user, allowing scientists to trust the data and get more robust -- and transparent -- results. […]

  • Clean and green: A moss that removes lead (Pb) from water
    on January 17, 2018 at 6:11 pm

    Researchers in Japan have demonstrated that that moss can be a green alternative for decontaminating polluted water and soil. Their study shows that in particular, the moss Funaria hygrometrica tolerates and absorbs an impressive amount of lead (Pb) from water. […]

  • Heavy-petroleum fuels raising vanadium emissions
    on December 15, 2017 at 5:10 pm

    Human emissions of the potentially harmful trace metal vanadium into Earth's atmosphere have spiked sharply since the start of the 21st century due in large part to industry's growing use of heavy oils, tar sands, bitumen and petroleum coke for energy, a new Duke study finds. These emissions now exceed those from all natural sources combined. Growing evidence suggests exposure to vanadium-rich aerosols can impair respiratory functions and exacerbate conditions such as asthma or COPD. […]

  • New database catalogues plants that soak up contamination
    on November 21, 2017 at 5:14 pm

    Hyperaccumulators are unusual plants that can absorb much larger amounts of metal compounds in their leaves and stems than normal plants, and they are very useful for cleaning up contaminated land. […]

  • Some Chinese coal ash too radioactive for reuse
    on November 10, 2017 at 3:40 am

    Many manufacturers use coal ash from power plants as a low-cost binding agent in concrete and other building materials. But a new study finds that coal ash from high-uranium deposits in China is too radioactive for this use. Some coal ash analyzed in the study contained radiation 43 times higher than the maximum safe limit set for residential building materials by the U.N. Scientific Committee on the Effects of Atomic Radiation. […]

  • New Amazon threat? Deforestation from mining
    on October 18, 2017 at 1:02 pm

    Sprawling mining operations in Brazil have caused roughly 10 percent of all Amazon rainforest deforestation between 2005 and 2015 -- much higher than previous estimates -- says the first comprehensive study of mining deforestation in the iconic tropical rainforest. Surprisingly, the majority of mining deforestation (a full 90%) occurred outside the mining leases granted by Brazil's government, the new study finds. […]

  • Diamonds show Earth still capable of ‘superhot’ surprises
    on September 21, 2017 at 1:55 pm

    Diamonds may be ‘forever’ but some may have formed more recently than geologists thought. A study of 26 diamonds, formed under extreme melting conditions in the Earth’s mantle, found two populations, one of which has geologically ‘young’ ages. The results show that certain volcanic events on Earth may still be able to create super-heated conditions previously thought to have only existed early in the planet’s history before it cooled. The findings may have implications for diamond prospecting. […]

  • The sand trap: Demand outpaces caution, knowledge
    on September 7, 2017 at 6:27 pm

    Sand, spanning miles of beaches, carpeting vast oceans and deserts, is a visual metaphor for limitless resources. Yet seize another metaphor -- sand in an hourglass, marking time running out. […]

  • Wolf behavior undeterred by tailings ponds and pit mines
    on August 30, 2017 at 2:34 pm

    New research shows that predation rates of moose have increased near areas of high human disturbance, but low human activity, such as tailings ponds and pit mines. […]

  • Shocking gaps in basic knowledge of deep sea life
    on August 21, 2017 at 10:33 pm

    Human interference in the deep sea could already be outpacing our basic understanding of how it functions. As a result, without increased research and an immediate review of deep ocean conservation measures, the creatures that live there face an uncertain future, scientists have warned. […]

  • Current threats to our oceans revealed
    on August 3, 2017 at 1:59 pm

    A survey of tens of thousands of marine studies from the last decade reveals current threats to our marine environment. These include: the effects of climate change, marine plastic pollution, conservation, as well as social and economic impacts. It is hoped the method used to obtain this information, which has only just been made possible with advances in computational power, will enable the development of robust policies that ensure the future health of our seas.

  • Challenging prevailing theory about how deep-sea vents are colonized
    on July 24, 2017 at 5:30 pm

    Despite being relatively close together, two recently discovered hydrothermal vent fields in the Gulf of California host very different animal communities. This finding contradicts a common scientific assumption that neighboring vents will share similar animal communities, and suggests that local geology and vent-fluid chemistry are important factors affecting vent communities. […]

  • Mountaintop coal mining causes Appalachian rivers to run 'consistently saltier'
    on July 13, 2017 at 7:30 pm

    Over time, alkaline salts and other contaminants from the coal residue and crushed rocks in valley fills leach into nearby streams and rivers, degrading water quality and causing dramatic increases in salinity that are harmful to downstream ecosystems. […]

  • Costs of coal storage and its impact on disadvantaged communities
    on July 5, 2017 at 5:30 pm

    While the negative health and environmental effects of mining and burning coal are well documented, simply transporting and storing coal can also adversely affect the health outcomes of individuals living near coal-fired power plants. New research explores the health and environmental costs of coal storage and transportation, finding that increases in the level of coal stockpiles held by US power plants increase local air pollution levels, which in turn increases the average infant and adult mortality rates in the communities near these plants. […]

  • Announcing the discovery of a new mineral: Nataliyamalikite
    on July 5, 2017 at 5:28 pm

    In the harshest of environments in far-east Russia, scientists have discovered a new mineral, which could revolutionize the future of the mining industry. […]

  • Biodiversity loss from deep-sea mining will be unavoidable
    on June 26, 2017 at 4:45 pm

    Biodiversity losses from deep-sea mining are unavoidable and possibly irrevocable, an international team of scientists, economists and lawyers argue. They say the International Seabed Authority, which is responsible for regulating undersea mining in areas outside national jurisdictions, must recognize the risk and communicate it clearly to member states and the public to spur discussions as to whether deep-seabed mining should proceed, and if so, what safeguards are needed to minimize biodiversity loss. […]
