Although many of these frogs are visually similar, scientists used DNA sequencing, museum specimens, frog calls, and micro CT scans of skeletons to distinguish the species.

Across the global construction and architecture sectors, researchers have spent decades searching for scalable, low-carbon alternatives to concrete and traditional clay masonry. According to structural energy data from the International Energy Agency, standard building materials are responsible for a massive share of global carbon emissions, driven by the high-heat kilns required to process cement and fire structural bricks.

When we think about how forests grow and regrow, we often think about colorful birds carrying berries or monkeys dropping fruit seeds. For a long time, these animals have been known as nature's seed dispersers, carrying seeds far from the parent plant and helping forests grow.

Forests with more tree species appear to be improving faster over time, according to a new global study published in Nature Climate Change. doi.org/10.1038/s41558-026-02698-7

Bacteria previously found only in Asia and the USA have been discovered for the first time ever in Brazil among the farmed fish and the finding poses a huge threat to the country's booming aquaculture industry. Researchers found four species of the genus Flavobacterium in 11 bacterial isolates.

Fifty years after two tons of American red crayfish were legally shipped into southern Spain to boost the rural economy, scientists have confirmed that the aggressive invasive species is in the Guadalquivir River basin to stay.

As Arctic permafrost thaws and coastlines erode, enormous quantities of ancient carbon that has sat frozen in the ground for thousands of years are being carried into the sea. Scientists have long worried that microorganisms in the ocean would break this carbon down and release it as greenhouse gases, adding a dangerous new feedback loop to climate change.

In January and February 2023, waves along a stretch of San Diego coastline briefly turned a striking shade of fuchsia, the result of a deliberate scientific experiment rather than any natural phenomenon. Researchers from UC San Diego's Scripps Institution of Oceanography and the University of Washington released a bright pink, non-toxic dye into Los Penasquitos Lagoon, a small tidal estuary within Torrey Pines State Beach and Natural Reserve, to study something surprisingly understudied in ocean science: how small-scale freshwater plumes behave once they reach the breaking surf zone along the coast.

In a remote patch of Colorado's Gunnison National Forest, four miles from the nearest ploughed road, a man known simply as Billy Barr has spent 52 consecutive winters recording daily snowfall, temperature and weather observations from his off-grid cabin at roughly 9,600 feet. Barr first began jotting down snow measurements in 1974, shortly after graduating from Rutgers University with a degree in environmental science, initially just to keep himself occupied through the long, isolated winters near Gothic, a former silver mining town now home to the Rocky Mountain Biological Laboratory.

Scientists have discovered a new monkey species in the Congo rainforest, a small black colobus with striking orange lips called Likweli. Known as Colobus congoensis, it is only the fifth new monkey found in Africa in 75 years.
