Wastewater management reverses widespread freshwater deoxygenation in China

Freshwater ecosystems worldwide have been suffering from declining oxygen levels—a trend known as deoxygenation—that threatens biodiversity, fisheries and ecosystem stability. However, a new study published in Nature Geoscience offers hope: targeted nutrient management via wastew

An iron-driven chain reaction may trigger mass death of harmful algae blooms

Over recent decades, harmful algal blooms have become increasingly common. These blooms often consist of bacteria called "cyanobacteria" in freshwater ecosystems. They can produce debilitating toxins, suffocate marine life by depleting oxygen in the water, and make water unsafe f

The invasive fern that science misidentified for decades

Salvinia molesta can double its biomass in 36 hours. It spreads across ponds, lakes and slow-moving waterways in a smothering green mat, blocking sunlight, consuming oxygen and collapsing the ecosystems beneath it. Now present in freshwater bodies across more than 60 countries, i

Warming can shift freshwater crustaceans to a 'greener' diet

Climate change is not only warming our lakes and rivers, it is also changing what invasive species eat. A new experimental study published in Limnology and Oceanography Letters shows that temperature-driven diet shifts in an invasive crustacean could alter its ecological role in

World's oceans break June heat record: EU monitor

The world's oceans just experienced their hottest June on record and could set fresh highs in the months ahead as El Niño and climate change drive temperatures even higher, scientists said Wednesday.

Congo River freshwater rides 49-day Atlantic eddy to travel 200 kilometers offshore

The Congo River is the second-largest river in the world, releasing an average of 40,000 cubic meters of water per second into the Atlantic Ocean. This huge discharge rate creates a large plume of fresh water that fans out 800 kilometers (500 miles) offshore.

How a new fungal genome-editing tool could open fresh paths to cancer treatments

Researchers have spent decades—and billions of dollars—sequencing animal and crop genomes, but fungi have historically been the forgotten middle child of genomics, only noticed when they're ruining bread or colonizing toes.

Newfound family ties link Scythian elite burials across the Eurasian steppe

A new ancient DNA study published in Science Advances provides evidence that political power among Scythian elites may have been inherited through family lineages that extended across multiple burial sites. By combining archaeology, anthropology and genetics, the new study offers

Wasted pumpkin peel can keep your food fresh

Researchers at Kyushu University have developed a new food preservation solution. Using pumpkin peel as a raw material, they synthesized a nanomaterial for food packaging that slows the deterioration of fruit and other produce while reducing transport damage. The findings were pu

Caddisfly silk gene evolves quickly without losing adhesive power

Caddisflies are among nature's master underwater builders, capable of spinning sticky silk that they use to form protective cases and webs in freshwater streams. Scientists like the University of Utah's Russell Stewart have long studied this bioadhesive material in the hope of us
