Chemical pollution in China: which metal poses the greatest risk to the Bohai region's freshwater ecosystem?

Professor Andrew Johnson and Dr Monika Jürgens, Environmental Scientists at the Centre for Ecology & Hydrology, contributed to a recent study looking at which metal presents the greatest risk to the freshwater ecosystem in the Bohai region of China. They explain more:

Thanks to support from the Natural Environment Research Council Newton Fund, the Centre for Ecology & Hydrology (CEH) has been collaborating with the Research Center for Eco-Environmental Sciences, in Beijing, China since the beginning of 2016 on the topic of chemical pollution in China. 

USGS Finds Elevated Levels of Arsenic, Radon, Methane in Some Private Wells in Lycoming County, Pennsylvania

Tests of 75 private drinking water wells in Lycoming County, in north-central Pennsylvania, found water from most of the sampled wells contained concentrations of radon that exceeded a proposed, nonbinding health standard for drinking water. Smaller percentages of the wells contained concentrations of arsenic or methane that exceed existing drinking water standards.

Flashy First Images Arrive from NOAA's GOES-16 Lightning Mapper

Detecting and predicting lightning just got a lot easier. The first images from a new instrument onboard NOAA’s GOES-16 satellite are giving NOAA National Weather Service forecasters richer information about lightning that will help them alert the public to dangerous weather.

Stanford study shows U.S. grasslands affected more by atmospheric dryness than precipitation

According to 33 years of remote sensing data, productivity of U.S. grasslands is more sensitive to dryness of the atmosphere than precipitation, important information for understanding how ecosystems will respond to climate change.

A new study showing dryness of the atmosphere affects U.S. grassland productivity more than rainfall could have important implications for predicting how plants will respond to warming climate conditions.

Imaging the Inner Workings of a Sodium–Metal Sulfide Battery for First Time

Understanding how the structural and chemical makeup of the material changes during the charge/discharge process could help scientists advance battery design for future energy storage needs

Sometimes understanding how a problem arises in the first place is key to finding its solution. For a team of scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, taking this approach led them to the cause of degraded performance in an operating sodium-ion battery.

United Kingdom CO2 Emissions Fall to Lowest Level in Nearly a Century

A record drop in coal use — coupled with the rapid growth of renewable energy, an expansion of energy efficiency programs, and an increase in burning natural gas for electricity — have driven carbon dioxide emissions in the UK to their lowest levels since the 1920s, according to a new study by the non-profit group, Carbon Brief.

The cold exterminated all of them

The Earth has known several mass extinctions over the course of its history. One of the most important happened at the Permian-Triassic boundary 250 million years ago. Over 95% of marine species disappeared and, up until now, scientists have linked this extinction to a significant rise in Earth temperatures. But researchers from the University of Geneva (UNIGE), Switzerland, working alongside the University of Zurich, discovered that this extinction took place during a short ice age which preceded the global climate warming. It’s the first time that the various stages of a mass extinction have been accurately understood and that scientists have been able to assess the major role played by volcanic explosions in these climate processes. This research, which can be read in Scientific Reports, completely calls into question the scientific theories regarding these phenomena, founded on the increase of CO2 in the atmosphere, and paves the way for a new vision of the Earth’s climate history.

Underwater mountains help ocean water rise from abyss

At high latitudes, such as near Antarctica and the Arctic Circle, the ocean’s surface waters are cooled by frigid temperatures and become so dense that they sink a few thousand meters into the ocean’s abyss.

Ocean waters are thought to flow along a sort of conveyor belt that transports them between the surface and the deep in a never-ending loop. However, it remains unclear where the deep waters rise to the surface, as they ultimately must. This information would help researchers estimate how long the ocean may store carbon in its deepest regions before returning it to the surface.

Turning food waste into tires

Tomorrow’s tires could come from the farm as much as the factory.

Researchers at The Ohio State University have discovered that food waste can partially replace the petroleum-based filler that has been used in manufacturing tires for more than a century.

In tests, rubber made with the new fillers exceeds industrial standards for performance, which may ultimately open up new applications for rubber.

New approach for matching production and consumption of renewable electricity promotes large-scale integration of solar and wind power

VTT Technical Research Centre of Finland is coordinating the BALANCE project, which brings together leading European research institutes in the field of electrochemical conversion. The project aims to demonstrate a technology that enables flexible storage of large amount of renewable power. Such technologies are needed for the further integration of additional wind and solar power. The European Commission funds the project by 2.5 million euros.
