GoJelly project officially kicks off

While the number of fish in our oceans continues to decrease, changing environmental conditions seem to favour jellyfish. They occur more often in large blooms. So far, they are considered annoying, if not dangerous. The project GoJelly aims to change that perception and to investigate the suitability of the organisms as microplastic filters, fertilizers or fish feed.

Heat loss from the Earth triggers ice sheet slide towards the sea

In North-East Greenland, researchers have measured the loss of heat that comes up from the interior of the Earth. This enormous area is a geothermal 'hot spot' that melts the ice sheet from below and triggers the sliding of glaciers towards the sea.

Radioactivity from oil and gas wastewater persists in Pennsylvania stream sediments

More than seven years after Pennsylvania officials requested that the disposal of radium-laden fracking wastewater into surface waters be restricted, a new study finds that high levels of radioactivity persist in stream sediments at three disposal sites. Radioactivity at these sites is 650 times higher than at unaffected sites upstream. The contamination comes from conventional, or non-fracked, oil and gas wastewater, which, under current state regulations, can still be treated and discharged into streams.

City lights setting traps for migrating birds

A new study has examined how light pollution lures birds into urban areas during fall migration, a trend that poses risk for the fowl that often fly into buildings and has increased with the addition of brighter LED lights. The researchers were interested in seeing what factors shape the birds' distributions and why they occur in certain areas.

Temporary 'bathtub drains' in the ocean concentrate flotsam

An experiment using hundreds of plastic drifters in the Gulf of Mexico shows that rather than simply spread out, as current calculations would predict, many of them clumped together in a tight cluster.

Long-term warming trend continued in 2017: NASA, NOAA

Continuing the planet's long-term warming trend, globally averaged temperatures in 2017 were 1.62 degrees Fahrenheit (0.90 degrees Celsius) warmer than the 1951 to 1980 mean, according to scientists.

20 percent more trees in megacities would mean cleaner air and water, lower carbon and energy use

Planting 20 percent more trees in our megacities would double the benefits of urban forests, like pollution reduction, carbon sequestration and energy reduction. The authors of the study say city planners, residents and other stakeholders should start looking within cities for natural resources and conserve the nature in our urban areas by planting more trees.

Crop failure in the Andes

Tough times lie ahead for rural farmers growing the Andes' staple crops -- corn and potatoes.

Microwave appliance usage could be as bad for the environment as cars, suggests new research

Microwave appliance usage across the EU alone emits as much carbon dioxide as nearly seven million cars, according to a new study. Researchers have carried out the first ever comprehensive study of the environmental impacts of microwave appliances, considering their whole life cycle, from 'cradle to grave.'

New research to help reduce number of algae blooms that form annually

A new study shows that sampling headwaters where streams form can identify which landscapes are resilient enough to handle the rigors of farming and which are vulnerable to leaching toxic residue into waterways.

Weather anomalies accelerate the melting of sea ice

Researchers reveal why Arctic sea ice began to melt in the middle of winter two years ago -- and that the increased melting of ice in summer is linked to recurring periods of fair weather.

Pharmaceuticals and other contaminants force fish to work much harder to survive

Pharmaceuticals and other human-made contaminants are forcing fish that live downstream from a typical sewage treatment plant to work at least 30 percent harder just to survive, researchers have found.

Shale gas is one of the least sustainable ways to produce electricity, research finds

Shale gas is one of least sustainable options for producing electricity, according to new research.

Sanchi oil spill contamination could take three months to reach mainland

Water contaminated by the oil currently leaking into the ocean from the Sanchi tanker collision is likely to take at least three months to reach land, and if it does the Korean coast is the most likely location. However, the oil's fate is highly uncertain, as it may burn, evaporate, or mix into the surface ocean and contaminate the environment for an extended duration.

Jet stream changes since 1960s linked to more extreme weather

Increased fluctuations in the path of the North Atlantic jet stream since the 1960s coincide with more extreme weather events in Europe such as heat waves, wildfires and flooding. The new research is the first reconstruction of historical changes in the North Atlantic jet stream prior to the 20th century. By using tree rings, the researchers developed a historical look at the position of the North Atlantic jet back to 1725.
