New research has looked into the potential effects of increased rainfall in regions being earmarked for expansion of temperate rainforests. Amid global calls for more trees to be planted as part of efforts to combat climate change, this study highlights the importance of factoring in soil conditions when looking at where and how to create the temperate rainforests of the future.

Episodes of heavy snowfall and rain likely contributed to a swarm of earthquakes over the past several years in northern Japan, researchers find. Their study shows climate conditions could initiate some earthquakes.

Local decision-makers looking for ways to reduce the impact of heat waves on their communities have a valuable new capability at their disposal: a new study on vegetation resilience. Scientists completed a study of how well vegetation survived extreme heat events in both urban and rural communities across the country in recent years. The analysis informs pathways for climate mitigation, including ways to reduce the effect of urban heat islands.

Pore pressure diffusion generated by carbon dioxide injected underground at a carbon storage site in the Illinois Basin is the likely cause of hundreds of microearthquakes that took place at the site between 2011 and 2012, according to a new analysis.

Two species of marine bacteria from the North Sea have established an unusual and sometimes destructive relationship to produce the important vitamin B12. The team's experiments show that the two microbial species have developed a coordinated strategy to obtain the scarce but essential vitamin.

Scientists have confirmed the identity of an unusual, ancient and Endangered species of fish that is living in the coastal rivers of Queensland, about 1400 km north of where it was previously known to live.

Freshwater bacteria with small genomes frequently undergo prolonged periods of adaptive stagnation. Based on genomic analyses of samples from European lakes, researchers uncovered specific evolutionary strategies that shape these bacteria's lifestyles. Understanding the evolutionary dynamics of aquatic microbial communities is key to safeguarding ecosystem services.

When old food packaging, discarded children's toys and other mismanaged plastic waste break down into microplastics, they become even harder to clean up from oceans and waterways. These tiny bits of plastic also attract bacteria, including those that cause disease. Researchers describe swarms of microscale robots (microrobots) that captured bits of plastic and bacteria from water. Afterward, the bots were decontaminated and reused.

Tipping points in the climate system can be the result of a slow but linear development. However, they can also be accompanied by a 'flickering', with two stable climatic states that alternate before a final transition occurs -- and the climate tips permanently.

Finding reliable, eco-friendly power sources is crucial as our world grapples with increasing energy needs and the urgent call to combat climate change. Solar energy offers one solution, with scientists devising ever more efficient materials for capturing sunlight.

In the ever-expanding search for energy resources, a new study has emerged from Mozambique's Maniamba Basin. Mozambique's Maniamba Basin could be a big source of natural gas.

Discharge from ships with so-called scrubbers cause great damage to the Baltic Sea. A new study shows that these emissions caused pollution corresponding to socio-economic costs of more than EUR 680 million between 2014 and 2022. At the same time, the researchers note that the shipping companies' investments in the much-discussed technology, where exhaust gases are 'washed' and discharged into the sea, have already been recouped for most of the ships. This means that the industry is now making billions of euros by running its ships on cheap heavy fuel oil instead of cleaner fuel.

As the region reckons with its toxic history of offshore dumping off the California coast, new findings raise troubling questions about whether the banned pesticide remains a threat to wildlife and human health.

To preserve the important intertidal areas and salt marshes off our coasts for the future, we need more turbid water. That is one of the striking conclusions from a new study.

By using experimental electrochemical analyses, mass spectrometry, and computational quantum chemistry modeling, the researchers created an 'atomic-scale storyline' to explain how ozone is generated on NATO electrocatalysts. They identified that some of the nickel in NATO is probably leaching out of the electrodes via corrosion, and these nickel atoms, now floating in the solution near the catalyst, can promote chemical reactions that eventually generate ozone.

Drones monitoring fields for weeds and robots targeting and treating crop diseases may sound like science fiction but is actually happening already, at least on some experimental farms. Researchers are working on driving forward the smart digitalization of agriculture and have now published a list of the research questions that will need to be tackled as a priority in the future.

Anthropologists suggest in a new study that establishing networks of 'sister cities' dedicated to addressing the impact of natural disasters can mitigate the devastation wrought by climate change.
