A new attempt to predict earthquakes has raised hopes that artificial intelligence could one day be used to limit earthquakes’ impact on lives and economies. The AI algorithm correctly predicted 70% of earthquakes a week before they happened during a seven-month trial in China. The system is limited because the AI needs an extensive database and years of seismic recordings to train itself on, but researchers said the effort is nonetheless a milestone for AI-driven earthquake forecasting. Researchers will soon begin testing the system at other locations.

Rivers across England have seen a significant improvement in river invertebrate biodiversity since 1989, shows a new study.

Researchers working to image New Zealand's Hikurangi earthquake fault have uncovered a sea's worth of water buried in the Earth's crust. The water was carried down by eroding volcanic rocks and is believed to be dampening the earthquake fault, allowing it to release most of the pent-up tectonic stress through harmless slow slip earthquakes.

The increasingly urgent climate crisis has led to a boom in commercial tree plantations in an attempt to offset excess carbon emissions. However, authors argue that these carbon-offset plantations might come with costs for biodiversity and other ecosystem functions. Instead, the authors say we should prioritize conserving and restoring intact ecosystems.

A shift in the way we think about the benefits mangroves provide to coastal regions could yield significant economic and biodiversity gains and protect millions from flooding, research has revealed.

Viruses in soil may not be as destructive to bacteria as once thought and could instead act like lawnmowers, culling older cells and giving space for new growth, according to research.

A recent study sheds new light on the elusive Roosmalens' dwarf porcupine, a poorly understood neotropical species. After 22 years of relative obscurity, this research uncovers vital information about its distribution, phylogenetics, and potential conservation threats, not only revealing its endemic presence in the Madeira biogeographical province but also expanding its known range in the southern Amazon.

It’s long been understood that human settlement contributes to conditions that make Pacific Islands more susceptible to wildfires, such as the devastating Aug. 8 event that destroyed the Maui community of Lahaina. But a new study from fire scientist shows that climate is an undervalued part of the equation.

Combinations of unfavorable weather conditions over several years can cause a decline in insect biomass.

Protecting large swaths of Earth's land can help stem the tide of biodiversity loss -- especially when those protected areas are in less disturbed landscapes and in countries with effective national governance. A new study looked at how amphibians, reptiles, mammals and birds fared in protected versus unprotected areas worldwide. Vertebrate abundance decreased five times more slowly inside protected areas, offering much-needed support for the United Nations' '30 by 30' conservation initiative.

Tree rings reveal a new kind of earthquake threat to the Pacific Northwest. These findings could have implications for seismic preparedness measures in the region.

Climate change and a range of human-caused factors have disrupted the habitats of many California native trees and other plant species. Efforts to protect or relocate plant species would be bolstered by understanding which habitats are best suited for each species. A new study identified a range of characteristics from more than 100 types of plants that can be analyzed to determine each species' preferred temperature and rainfall amount.

The mechanism facilitating the smooth movement of the oceanic lithosphere over the underlying asthenosphere (upper mantle) remains poorly understood. Recently, researchers from Japan investigated the effect of water on the seismic properties of olivine rocks, finding that water retention in the asthenosphere can induce sharp drops in shear wave velocity. This also explained other seismic changes observed at the lithosphere-asthenosphere boundary. These findings provide invaluable insights into the diverse seismic activities on Earth.

New research has validated at scale, one of the theories that has underpinned ecology for over half a century. In doing so, the findings raise further questions about whether models should be revised to capture human impacts on natural systems.

An experiment using water from a large wastewater treatment plant has shown that this water continues to affect river diversity and the trophic web (food web) despite being properly treated and highly diluted before discharge. The study shows that the limits currently in place and the procedures used to treat wastewater may not be sufficient to protect the natural properties of food webs.

Ecological disturbances like wildfires disrupt microbial communities. Researchers found that dispersal played a pivotal role in re-establishing surface-level communities.

Trees depend on fungi for their well-being. As climate change and global warming cause higher temperatures and amplified drought, little is known about how these important fungi will respond. To investigate this issue, a research team conducted a climate change experiment where they exposed boreal and temperate tree species to warming and drought treatments to better understand how fungi and their tree hosts respond to environmental changes. Their findings revealed that the combined effects of warming and water stress will likely result in major disturbances of ectomycorrhizal networks and may harm forest resilience and function.

Many pathogens, including the virus that causes COVID-19, are thought to have originated in wild animals before spilling into human populations.

The research team generated a series of fire susceptibility maps. These show the proportion of Australia experiencing 'high' or 'very high' fire susceptibility increasing from 14.9% now to 15.66% by 2070 -- while fire susceptibility of areas suitable for the plants that koalas depend on is tipped to jump from 39.56% to 44.61% by 2070.

• Twenty-year experiment finds that active replanting beats natural recovery for restoring logged tropical forests. • The higher the diversity of replanted tree species, the more quickly canopy area and biomass recovered. • Results emphasize the importance of preserving biodiversity in pristine forests and restoring it in recovering logged forest.
