Study of greater Yellowstone pronghorn finds highway crossing structures a conservation success

A recently published study has confirmed that efforts to protect migrating pronghorn by installing wildlife crossing structures over highways have succeeded, in terms of the increased success rate of pronghorn crossings over time.

Predicting landslide boundaries two weeks before they happen

Researchers have developed a software tool that uses applied mathematics and big data analytics to predict the boundary of where a landslide will occur, two weeks in advance.

First reliable estimates of highly radioactive cesium-rich microparticles released by Fukushima disaster

Scientists have for the first time been able to estimate the amount of radioactive cesium-rich microparticles released by the disaster at the Fukushima power plant in 2011. This work hsd significant health and environmental implications.

Faster way to make mineral to remove carbon dioxide from atmosphere

Scientists have developed an accelerated way to produce magnesite, a mineral which can capture the greenhouse gas carbon dioxide from the atmosphere, at room temperature. Removing carbon dioxide from the atmosphere would slow global warming. This work takes a different approach to existing processes, and may make it economically viable, but it is at an early stage and is not yet an industrial process.

Scientists get new tool to track new pathogen killing frogs

An undergraduate researcher has developed a method to screen frogs for an infectious disease that has been linked to mass die-offs of frogs around the world. Thanks to her method, scientists will be able to track the disease and try to figure out why it is triggering the deaths.

Effects of climate warming seen in tallgrass prairie ecosystem

Ecologists have completed a new study on the effects of climate warming on soil microbes in a long-term climate change experiment at a tallgrass prairie ecosystem. The new study shows that climate warming will affect microbial communities in the future, and future community states will be more predictable under warmed climate. Eventually, microbial communities will produce different functions and feedbacks to climate warming.

Natural refrigerant replacements could reduce energy costs and conserve the environment

The 1987 Montreal Protocol and the 1997 Kyoto Protocol called for countries around the world to phase out substances that deplete the ozone layer, but many HVAC systems still use synthetic refrigerants that violate those international agreements and inflict environmental damage. Recently, researchers investigated how natural refrigerants could be used in geothermal heat pumps to reduce energy consumption and operating costs.

Diving robots find Antarctic winter seas exhale surprising amounts of carbon dioxide

A new study uses data gathered by floating drones in the Southern Ocean over past winters to learn how much carbon dioxide is transferred by the surrounding seas. Results show that in winter the open water nearest the sea ice surrounding Antarctica releases significantly more carbon dioxide than previously believed.

Trees and climate change: Faster growth, lighter wood

Trees are growing more rapidly due to climate change. This sounds like good news. After all, this means that trees are storing more carbon dioxide from the atmosphere in their wood and hence taking away the key ingredient in global warming. But is it that simple? A team analyzed wood samples from the oldest existing experimental areas spanning a period of 150 years -- and reached a surprising conclusion.

Glacier depth affects plankton blooms off Greenland

The unusual timing of highly-productive summer plankton blooms off Greenland indicates a connection between increasing amounts of meltwater and nutrients in these coastal waters. Researchers now show that this connection exists, but is much more complex than widely supposed. Whether increasing meltwater has a positive or negative effect on summertime phytoplankton depends on the depth at which a glacier sits in the ocean.

Severe declines of mountain hares on Scottish grouse moors

Mountain hare numbers on moorlands in the eastern Highlands have declined to less than one per cent of their initial levels, according to a long-term scientific study.

Fishing quotas upended by nuclear DNA analysis

Fishing quotas have been decided using an inadequate method for decades, according to a new study. The same method has also been used to decide about culling, hunting quotas, or translocating threatened species. Analyzing the nuclear genome of sardines shows previously unrecognized genetic differences between populations, which are not identified by the go-to-method for Isolation-By-Distance, mitochondrial DNA analysis.

Illinois' imperiled eastern massasauga rattlesnakes retain genetic diversity

A long-term study of eastern massasauga rattlesnakes in Illinois reveals that -- despite their alarming decline in numbers -- the few remaining populations have retained a surprising amount of genetic diversity.

California water managers vary in use of climate science

Lack of climate change adaptation among water utilities can put water supplies and the people dependent on them at risk, especially in marginalized communities, a new article suggests.

A record number of Americans watched the 2017 solar eclipse -- and sought science afterward

The 2017 total solar eclipse spurred a flurry of interest about solar eclipses, according to the final report of a survey led by the University of Michigan.

How Neolithic people adapted to climate change

Research has uncovered evidence that early farmers were adapting to climate change 8,200 years ago.

When it comes to regrowing tails, neural stem cells are the key

It's a longstanding mystery why salamanders can perfectly regenerate their tails whereas lizard tails grow back all wrong. By transplanting neural stem cells between species, researchers have discovered that the lizard's native stem cells are the primary factor hampering tail regeneration.

Europe needs coastal adaptation measures to avoid catastrophic flooding by the end of the century

Coastal floods could impact up to 3.65 million people every year in Europe by 2100, according to a new study.

Algorithm provides early warning system for tracking groundwater contamination

Scientists have developed a low-cost method for real-time monitoring of pollutants using commonly available sensors.

EU households waste over 17 billion kg of fresh fruit and vegetables a year

A recent article finds that EU households generate about 35.3 kg of fresh fruit and vegetable waste per person per year, 14.2 kg of which is avoidable.
