Sometimes, a little snot goes a long way. And not just in the physical, stretchy sense. Today, some decade-old snot collected from the sinuses of cancer patients revealed a new technique to forecast how flu evolves.

A new analysis shows that septic systems in the United States routinely discharge pharmaceuticals, consumer product chemicals, and other potentially hazardous chemicals into the environment. The study, published June 15 in the journal Environmental Science & Technology, is the most comprehensive assessment to date of septic systems as important sources of emerging contaminants, raising health concerns since many of these chemicals, once discharged, end up in groundwater and drinking water supplies.

Known as contaminants of emerging concern (CECs), these types of pollutants are frequently detected in U.S. rivers, lakes, and drinking water supplies. However, the U.S. Environmental Protection Agency does not currently regulate them in drinking water. Many emerging contaminants are hormone disruptors.

NOAA met with ocean observations experts from six nations and 13 global organizations in May 2017 in Honolulu, Hawaii, to plan for the redesign of the Tropical Pacific Observing System by the year 2020 (TPOS 2020).

TPOS is an ocean-based monitoring network comprised of a variety of observing technologies, operated by NOAA and other foreign partners.  This network provides the essential ocean data needed to understand important environmental phenomenon and develop weather and climate forecasts for the US and countries around the world.

Biodiversity losses from deep-sea mining are unavoidable and possibly irrevocable, an international team of 15 marine scientists, resource economists and legal scholars argue in a letter published today in the journal Nature Geoscience.

The experts say the International Seabed Authority (ISA), which is responsible under the UN Law of the Sea for regulating undersea mining in areas outside national jurisdictions, must recognize this risk. They say it must also communicate the risk clearly to its member states and the public to inform discussions about whether deep-seabed mining should proceed, and if so, what standards and safeguards need to be put into place to minimize biodiversity loss.

Monitoring changes to the amount of wetlands in regions where permafrost is thawing should be at the forefront of efforts to predict future rates of climate change, new research shows.

Permafrost - frozen ground - holds huge amounts of carbon which may be released into the atmosphere as the climate warms and these soils thaw. For this reason it is critically important to know where thaw is taking place and how much carbon is being exposed.
