• Bacteria living in marine sponge produce toxic compounds found in man-made products

    Researchers have discovered for the first time that a common marine sponge hosts bacteria that specialize in the production of toxic compounds nearly identical to man-made fire retardants, a finding that could help scientists better understand the human health implications of these common additives.

    The new findings, by scientists at the Scripps Institution of Oceanography (SIO) at the University of California, San Diego, moved the research team a step closer to unraveling the mysteries of this powerful group of chemical compounds, known as polybrominated diphenyl ethers (PBDEs).

  • More natural dust in the air improves air quality in eastern China

    Man-made pollution in eastern China's cities worsens when less dust blows in from the Gobi Desert, according to a new study published May 11 in Nature Communications.

  • MIT researchers develop new way to clear pollutants from water

    When it comes to removing very dilute concentrations of pollutants from water, existing separation methods tend to be energy- and chemical-intensive. Now, a new method developed at MIT could provide a selective alternative for removing even extremely low levels of unwanted compounds.

  • Experiments show that a few self-driving cars can dramatically improve traffic flow

    The presence of just a few autonomous vehicles can eliminate the stop-and-go driving of the human drivers in traffic, along with the accident risk and fuel inefficiency it causes, according to new research. The finding indicates that self-driving cars and related technology may be even closer to revolutionizing traffic control than previously thought.

  • Poor overall environmental quality linked to elevated cancer rates

    Nationwide, counties with the poorest quality across five domains – air, water, land, the built environment and sociodemographic – had the highest incidence of cancer, according to a new study published in the journal Cancer.

  • Microbes versus mercury

    Mercury is a powerful poison. It can cause brain damage, tremors, paralysis and death.

    But two researchers at the University of Ottawa’s Department of Biology have found a way to neutralize this toxic metal by pitting it against a small but mighty foe — a group of microorganisms known as purple non-sulphur bacteria.

  • Polluted air can generate power

    Researchers from the University of Antwerp and KU Leuven have succeeded in developing a process that purifies air and, at the same time, generates power. The device must only be exposed to light in order to function.

  • Researchers find monetary value of air quality in China

    Researchers at the Yale School of Public Health and Peking University have found that Chinese families are willing to invest up to 6 percent of their annual income in efforts to improve air quality.

    Published in Ecological Economics on March 7, the study aimed to determine the amount people are willing to pay for efforts to reduce air pollution, such as environmental policies to introduce more electric cars and natural gas heating. The researchers found that on average, families with children under the age of 6 are willing to invest 5.9 percent of their annual income, while families without children under 6 years old are willing to pay 3.3 percent.

  • Study measures air pollution increase attributable to air conditioning

    When summer temperatures rise and people turn to their air conditioners to stay cool, something else also increases: air pollution.

    A new study published Wednesday (May 3, 2017) in the journal Environmental Science & Technology shows that the electricity production associated with air conditioning causes emissions of sulfur dioxide, nitrogen oxides and carbon dioxide to increase by hundreds to thousands of metric tons, or 3 to 4 percent per degree Celsius (or 1.8 degrees Fahrenheit).

  • Turning chicken poop and weeds into biofuel

    Chicken is a favorite, inexpensive meat across the globe. But the bird’s popularity results in a lot of waste that can pollute soil and water. One strategy for dealing with poultry poop is to turn it into biofuel, and now scientists have developed a way to do this by mixing the waste with another environmental scourge, an invasive weed that is affecting agriculture in Africa. They report their approach in ACS’ journal Energy & Fuels.
