Much of the methane released into the southern Baltic Sea from the Nord Stream gas pipeline has remained in the water. This is shown by measurements taken by researchers from the University of Gothenburg.

Some areas of the Amazon rainforest are more resilient to drought than others, new research shows. But if not managed carefully, we could 'threaten the integrity of the whole system,' researchers say.

Archipelago case-study shows that removing invasive rats and restoring native vegetation could help bring back hundreds of thousands of breeding pairs of seabirds lost to tropical islands. Calculating that there are enough fish to sustain restored seabird populations should be an important consideration for restoration projects, scientists say. Restored seabird populations also provide huge boost to the health of surrounding coral reef ecosystems through restored nutrient cycles.

The rise of advanced artificial intelligence (edge AI) could well mark the beginning of a new era for sustainable agriculture. A recent study proposes a roadmap for integrating this technology into farming practices. The aim? To improve the efficiency, quality and safety of agricultural production, while addressing a range of environmental, social and economic challenges.

Newfound evidence reveals that the upsurge of the exotic Nile perch in Lake Victoria had long-lasting effects on the genetic diversity of various local cichlid species, report scientists. Through large-scale comparative genomic analyses, the researchers found concrete proof in the collective genome of multiple species that this artificially introduced perch decimated many local fish populations, causing a 'bottleneck effect.'

As the world's largest unfrozen freshwater resource, groundwater is crucial for life on Earth. Researchers have investigated how global warming is affecting groundwater temperatures and what that means for humanity and the environment. Their study indicates that by 2100, more than 75 million people are likely to be living in regions where the groundwater temperature exceeds the highest threshold set for drinking water by any country.

A major earthquake 2,500 years ago caused one of the largest rivers on Earth to abruptly change course, according to a new study. The previously undocumented quake rerouted the main channel of the Ganges River in what is now densely populated Bangladesh, which remains vulnerable to big quakes.

Researchers hope their DIY machine will help designers around the world experiment with making their own, sustainable fashion and other textiles from a range of natural ingredients -- maybe even the chitin in crab shells or agar-agar from algae.

While farmer surveys suggest that carbon prices are still too low relative to the paperwork these programs demand, a new study finds that money alone does not explain either farmers' doubts about carbon markets or their interest in regenerative agriculture. Instead, many farmers view improving soil health as a way to improve their quality of life by reducing their dependence on agrochemical companies' products and advice.

Most people today would lean towards environmentally friendly life choices, but not at the expense of being clean. When it comes to our washing habits, the fear of being perceived as dirty often wins out over the desire to act in an environmentally friendly way. And the more inclined we are to feel disgusted, the more we wash our clothes. This is shown by a unique study that examines the driving forces behind our laundering behaviours and provides new tools for how people's environmental impact can be reduced.

The understanding of the global zinc cycle in our oceans has important implications in the context of warming oceans. A warmer climate increases erosion, leading to more dust in the atmosphere and consequently more dust being deposited into the oceans. More dust means more scavenging of zinc particles, leading to less zinc being available to sustain phytoplankton and other marine life, thereby diminishing the oceans' ability to absorb carbon.

When it comes to the ocean's response to global warming, we're not in entirely uncharted waters. A new study shows that episodes of extreme heat in Earth's past caused the exchange of waters from the surface to the deep ocean to decline.

Scientists found elevated mercury levels in dolphins in the U.S. Southeast. The highest levels were found in dolphins in Florida's St. Joseph and Choctawhatchee Bays. Researchers study dolphins because they are considered a sentinel species for oceans and human health. Like us, they are high up in the food chain, live long lives, and share certain physiological traits. Some of their diet is most vulnerable to mercury pollution and is also eaten by people.

The Western U.S. is heavily reliant on mountain snowpacks and their gradual melt for water storage and supply, and climate change is expected to upend the reliability of this natural process. Many agricultural communities in this part of the country are examining ways to adapt to a future with less water, and new research shows that a focus on supplementing water supply by expanding reservoir capacity won't be enough to avert future water crises.

Researchers have discovered a new species of medium-sized venomous snake in Yunnan, China. Ovophis jenkinsi is dark brownish-grey in color with trapezoidal patches on its back. It is endemic to China's Yingjiang County and is not difficult to find in the wild. In the future, researchers plan to collect more information about this new species, including its appearance, distribution, and habits.

New research highlights inequities between downstream and upstream countries that share the same watershed. The study outlines how international agreements can better address shared resource problems and call for greater collaboration and coordination between these international neighbors.

An international research team has discovered the oldest known marine plant using a novel genetic clock. This 1400-year-old seagrass clone from the Baltic Sea dates back to the Migration Period. The research project is a significant step towards better understanding and protecting marine ecosystems.

What species live in this coral reef, and are they healthy? Chemical clues emitted by marine organisms might hold that information. But in underwater environments, invisible compounds create a complex 'soup' that is hard for scientists to decipher. Now, researchers have demonstrated a way to extract and identify these indicator compounds in seawater. They found metabolites previously undetected on reefs, including three that may represent different reef organisms.

Australia's ski industry is at risk of major disruptions and shorter seasons if the current level of climate pollution continues, according to new modelling. The report found the average ski season across all resorts in Australia will be 44 days shorter by 2050 under a mid-greenhouse gas emissions scenario and 55 days shorter under a high-emissions scenario.

Scientists are getting closer to detecting bushfires in record time, thanks to cube satellites with onboard AI now able to detect fires from space 500 times faster than traditional on-ground processing of imagery.
