How is climate change affecting the permanently frozen soils of the Arctic? What will the consequences be for the global climate, human beings, and ecosystems? And what can be done to stop it?

Using a method that works backward from a set of observed earthquakes to test seismic models that fit those observations, researchers working in the Delaware Basin were able to determine whether earthquakes in the region since 2017 were caused by oil and gas operations.

The first high-quality genome of the desert locust -- those voracious feeders of plague and devastation infamy and the most destructive migratory insect in the world -- has been produced. The genome of the desert locust (Schistocerca gregaria) is enormous at just under 9 billion base pairs, nearly three times the size of the human genome. The size of the desert locust's chromosomes is remarkable; compare them to those of the model fruit fly Drosophila melanogaster, the first insect genome ever assembled. Many of the desert locust's individual chromosomes are larger than the entire fruit fly genome. Next to the fruit fly, it's like an 18-wheeler next to a compact car.

As the need to address climate change becomes increasingly urgent so too does the concurrent need for proactive stewardship of the Earth's rapidly changing biosphere, according to new research.

Melting ice in the Arctic Ocean could yield new trade routes in international waters, reducing the shipping industry's carbon footprint and weakening Russia's control over trade routes through the Arctic, a study found.

Restoration of mangroves and coral reefs can be a cost-effective solution for coastal flood reduction in more than 20 countries across the Caribbean. Researchers used methods from the risk and insurance industry to provide rigorous valuations of these natural defenses and show that they can deliver a positive return on investment, with the benefits from reduced flood damage exceeding the costs of restoration. The results point toward new opportunities to support restoration efforts with funds from sources that support hazard mitigation, climate adaptation, and disaster recovery, including FEMA.

A new study has found that invading subtropical corals will survive and thrive in coastal Sydney, which could spell trouble for existing Sydney coral species.

A new population of polar bears documented on the southeast coast of Greenland use glacier ice to survive despite limited access to sea ice. This small, genetically distinct group of polar bears could be important to the future of the species in a warming world.

Cheatgrass, an invasive annual grass that has invaded Nevada rangelands, is responsible for much of the increasing wildfire danger in the Intermountain West. However, scientists have discovered that fire danger can be reduced through the application of targeted cattle grazing in the dormant growing season by attracting the cattle with stations containing protein feed supplements.

By coexisting more closely with mangroves, tropical coral species may have found an alternative habitat where they can thrive in the face of climate change.

A new study in Ocean and Coastal Management shows that seagrass fisheries provide a reliable safety-net for poor, since fishermen perceive those habitats to maintain large fish catches over time. Surprisingly, even more so than coral reef fisheries, which people normally associate with small-scale fishery.

Researchers conducted an eight-year experiment that found that climate warming played a predominant role in shaping microbial biodiversity, with significant negative effect.

Prehistoric coral reefs dating back up to 250 million years extended much further away from the Earth's equator than today, new research has revealed.

Scientists have found evidence that the Earth's inner core oscillates, contradicting previously accepted models that posited it consistently rotates at a faster rate than the planet's surface.

The relatively pristine coral populations of WA's inshore Kimberley region are better equipped to survive ocean warming than the World Heritage-listed Ningaloo Marine Park, according to a new study.

Extensively used grassland is host to a high degree of biodiversity, and performs an important climate protection function as a carbon sink and also serves for fodder and food production. However, these ecosystem services are jeopardized if productivity on these lands is maximized and their use therefore intensified. Researchers have now described how satellite data and machine learning methods enable to assess land-use intensity.

A genetic variant that is present in nearly 30% of Greenlanders is linked to high cholesterol and an increased risk of cardiovascular disease, according to a new study.

New models that show how the continents were assembled are providing fresh insights into the history of the Earth and will help provide a better understanding of natural hazards like earthquakes and volcanoes.

In a 'seismological wind tunnel,' engineers demonstrate the impact of rock gouge -- ground-up rock along a fault boundary -- on earthquake propogation.

What's the relationship between people's perception of beauty and animals' conservation needs? According to a machine-learning study, the reef fishes that people find most beautiful tend to be the lowest priority for conservation support.
