Mice surprise: Researchers discover new native species      (via sciencedaily.com)     Original source 

Australia can lay claim to two new species of native rodent thanks to a new study. The aptly named delicate mouse was previously thought to be a single species spanning a massive stretch of the country from the Pilbara in Western Australia, across parts of the Northern Territory and through Queensland down to the New South Wales border. We now know there are three distinct species.

Gulf corals still suffering more than a decade after Deepwater Horizon oil spill, scientists report      (via sciencedaily.com)     Original source 

Deep-water corals in the Gulf of Mexico are still struggling to recover from the devastating Deepwater Horizon oil spill in 2010, scientists report at the Ocean Science Meeting in New Orleans. Comparing images of more than 300 corals over 13 years -- the longest time series of deep-sea corals to date -- reveals that in some areas, coral health continues to decline to this day.

Measuring neutrons to reduce nuclear waste      (via sciencedaily.com)     Original source 

Nuclear power is considered one of the ways to reduce dependence on fossil fuels, but how to deal with nuclear waste products is a concern. Radioactive waste products can be turned into more stable elements, but this process is not yet viable at scale. New research reveals a method to more accurately measure, predict and model a key part of the process to make nuclear waste more stable. This could lead to improved nuclear waste treatment facilities and also to new theories about how some heavier elements in the universe came to be.

New nuclei can help shape our understanding of fundamental science on Earth and in the cosmos      (via sciencedaily.com)     Original source 

In creating five new isotopes, scientists have brought the stars closer to Earth. The isotopes are known as thulium-182, thulium-183, ytterbium-186, ytterbium-187 and lutetium-190.

Reforestation programs could threaten vast area of tropical grasslands      (via sciencedaily.com)     Original source 

New research reveals the scale of inappropriate reforestation projects across Africa. A new study reveals that an area the size of France is threatened by forest restoration initiatives, such as the AFR100 initiative (African Forest Landscape Restoration Initiative), due to inappropriate restoration in the form of tree-planting.

Climate change drove the emergence of West Nile virus in Europe      (via sciencedaily.com)     Original source 

Researchers demonstrate the contribution of climate change to the spatial expansion of West Nile virus in Europe, a virus that constitutes a new public health threat in the continent. Their findings highlight a notable increase in the area ecologically suitable for the virus circulation since the beginning of last century and an increase in the human population at risk of exposure, due in part to climate change.

Australia's most at-risk bird species share some common traits      (via sciencedaily.com)     Original source 

Australian birds that live on islands are among the species most at risk of extinction, a first-of-its-kind study has shown. Australia has over 750 native bird species. But many of them are facing an uncertain future.

Scientists create effective 'spark plug' for direct-drive inertial confinement fusion experiments      (via sciencedaily.com)     Original source 

Scientists completed several successful attempts to fire 28 kilojoules of laser energy at small capsules filled with deuterium and tritium fuel, causing the capsules to implode and produce a plasma hot enough to initiate fusion reactions between the fuel nuclei. These results demonstrate an effective 'spark plug' for direct-drive methods of inertial confinement fusion.

Rare 3D fossils show that some early trees had forms unlike any you've ever seen      (via sciencedaily.com)     Original source 

In the fossil record, trees typically are preserved with only their trunks. They don't usually include any leaves to show what their canopies and overall forms may have looked like. In a new study, researchers describe fossilized trees from New Brunswick, Canada with a surprising and unique three-dimensional crown shape.

Physicists develop highly robust time crystal      (via sciencedaily.com)     Original source 

Researchers recently succeeded in producing a highly durable time crystal that lived millions of times longer than could be shown in previous experiments. By doing so, they have corroborated an extremely interesting phenomenon that Nobel Prize laureate Frank Wilczek postulated around ten years ago and which had already found its way into science fiction movies.

Fungal-rich soil may improve green roofs      (via sciencedaily.com)     Original source 

Green roofs have become increasingly popular thanks to their benefits related to climate adaptation, mitigation, and urban biodiversity management. But, in the U.S., green roofs are typically planted with non-native plants in sterile soils, and their effectiveness declines over time. A new study finds that managing green roof soil microbes boosts healthy urban soil development, which is a methodology that could be applied to support climate resilience in cities.

As sea otters recolonize California estuary, they restore its degraded geology      (via sciencedaily.com)     Original source 

As sea otters recolonize a California estuary, they are restoring its degraded geology by keeping populations of overgrazing marsh crabs in check, a new study shows. The crabs' appetite for plant roots, and their tunneling behavior had caused many of the estuary's marshes and creekbanks to erode and collapse in the otters' absence. Today, erosion has slowed by up to 90% in areas with large otter populations and marshes and streambeds are restabilizing.
