NIH researchers and their collaborators found that inhaling unfragmented hyaluronan improves lung function in patients suffering from severe exacerbation of COPD. Hyaluronan is a sugar secreted by living tissue that acts as a scaffold for cells. Utilized as a treatment, hyaluronan decreased the number of days in the hospital.
In a first-of-its-kind study, researchers discovered that light pollution leads to more than just wasted energy and washed-out starlight--it can increase the likelihood of a preterm birth by almost 13%.
Methane emissions from coal mining are likely much higher than previously calculated, according to new research. That’s due mainly to emissions from abandoned mines and higher methane content in deep coal seams.
Irvine, Calif., Jan. 27, 2021 — One of President Joe Biden’s first post-inauguration acts was to realign the United States with the Paris climate accord, but a new study led by researchers at the University of California, Irvine demonstrates that rising emissions from human land-use will jeopardize the agreement’s goals without substantial changes in agricultural practices.
The Ganges River - with the combined flows of the Brahmaputra and Meghna rivers - could be responsible for up to 3 billion microplastic particles entering the Bay of Bengal every day, according to new research.
Living near an abundance of green vegetation can offset the negative effects of air pollution on blood vessel health. The first-of-its-kind study is published ahead of print in the American Journal of Physiology-Heart and Circulatory Physiology.

Oxygen levels in the ancient oceans were surprisingly resilient to climate change, new research suggests.
Cars, trains, planes: For two thirds of the European population, traffic noise is part of everyday life. However, the right environment can have a major impact on this nuisance, as Empa researchers have found out. Green spaces in urban areas help to make road and railroad noise less of a nuisance. Only in the case of aircraft noise does this seem counterproductive: the greener the surroundings, the more disturbing the aircraft noise.
“Swiss Army knife” catalyst can bring the combustion temperature of methane down by about half – from above 1400 degrees Kelvin down to 600 to 700 degrees Kelvin.
Positive "tipping points" could spark cascading changes that accelerate action on climate change, experts say.
The American Thoracic Society opposes the EPA’s final rule on Data Transparency issued in the waning days of the Trump Administration. The final rule, which is the focus of a press conference today, is a continuation of the Trump Administration's persistent attack on the science showing the adverse health effects of environmental pollution. This rule would exclude vital scientific data from future EPA decision-making and make patient confidential information more vulnerable to public disclosure.
A fast, green and one-step method for producing porous carbon spheres, which are a vital component for carbon capture technology and for new ways of storing renewable energy, has been developed by Swansea University researchers.
Mussels, oysters and scallops have the highest levels of microplastic contamination among seafood, a new study reveals.

Plastics contain and leach hazardous chemicals, including endocrine-disrupting chemicals (EDCs) that threaten human health. An authoritative new report, Plastics, EDCs, & Health, from the Endocrine Society and the IPEN (International Pollutants Elimination Network), presents a summary of international research on the health impacts of EDCs and describes the alarming health effects of widespread contamination from EDCs in plastics.
The landmark Clean Air Act (CAA) turns 50 this month, and its impact has been dramatic: Ambient measures of pollutants have fallen more than 90% in some areas, and cleaner air is credited with preventing hundreds of thousands of premature deaths. Despite this success, the debate rages on over whether the costs to industry of further pollution reductions are too high. After five decades, has the CAA accomplished its mission?
University of South Australia thermal energy researcher Professor Frank Bruno has been awarded almost $1 million by the Federal Government to find a solution to agricultural pollution in Australia and India.
Anyone who wants to protect themselves and others from a COVID-19 infection wears a mask these days. But what about the environmental impact of this mass product, which is used millions of times over? Which factors are relevant for sustainable design? Empa researchers have examined these questions by means of life cycle assessment analyses, using cotton masks and disposable masks as an example.
A new study published in the Environmental Health Perspectives connects insulin resistance and repetitive ozone exposure to the development of interstitial lung disease.
Researchers from NUS have discovered a new strain of bacterium that can remove both nitrogen and phosphorous from sewage wastewater. Their findings offer a simpler, cheaper and greener method of wastewater treatment.
A new study shows that strong and rapid action to cut emissions of carbon dioxide and other greenhouse gases will help to slow down the rate of global warming over the next twenty years.
The Endocrine Society and IPEN will release a comprehensive joint report Dec. 15 on endocrine-disrupting chemicals in plastics and the threat they pose to public health. Experts will share highlights from the report during a virtual news conference Dec. 15.
A University of Washington study provides the first look at how much noise pollution is impacting the Olympic Peninsula in Washington state. The paper found that aircraft were audible across a large swath of the peninsula at least 20% of weekday hours, or for about one hour during a six-hour period. About 88% of all audible aircraft in the pre-pandemic study were military planes.
A team led by researchers at the University of Washington Tacoma, UW and Washington State University Puyallup have discovered a chemical that kills coho salmon in urban streams before the fish can spawn.

Schools with a higher proportion of students of color and from households experiencing poverty were exposed to more peak pollution days than were schools serving middle- to upper- class and predominately white students.
A new study led by researchers at UC San Francisco has found that among older Americans with cognitive impairment, the greater the air pollution in their neighborhood, the higher the likelihood of amyloid plaques - a hallmark of Alzheimer's disease.
U.S. pollution regulations meant to protect humans from dirty air are also saving birds. So concludes a new continentwide study published today in The Proceedings of the National Academy of Sciences. Study authors found that improved air quality under a federal program to reduce ozone pollution may have averted the loss of 1.5 billion birds during the past 40 years.

A new report by the Center for State Policy Analysis (cSPA) at Tufts University’s Tisch College describes the potential impact of the Transportation Climate Initiative (TCI) — a proposal to curb emissions from gasoline and diesel fuel — in Massachusetts and other Northeastern states.
Older women who live in locations with higher levels of air pollution may have more brain shrinkage, the kind seen in Alzheimer’s disease, than women who live in locations with lower levels, according to a new study published in the November 18, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study looked at fine particle pollution and found that breathing in high levels of this kind of air pollution was linked to shrinkage in the areas of the brain vulnerable to Alzheimer’s disease.

In April 2020, as remote work and social distancing policies were in place in Delaware and a number of other states, there was a sense the skies were clearer and less polluted with fewer people on the road. But new research from a team led by University of Delaware, Penn State and Columbia University researchers found a murkier picture.
Los Alamos National Laboratory is partnering with four other national laboratories and four academic institutions in a new program to tackle the problem of plastic pollution.
