Earthworm invasion

Analysis reveals imported earthworm species have colonized large swaths of North America, and represent a largely overlooked threat to native ecosystems. The researchers warn of the need to better understand and manage the invaders in our midst.

How mice choose to eat or to drink

A new Stanford study uses behavioral analysis, neural engineering, electrophysiology, and math to explore how mice decide whether to eat or drink when they are both hungry and thirsty.

Forecasting malaria

The study integrates climate, land use, and socioeconomic data to explain and predict malaria dynamics at the village level. The approach could inform health care practitioners and make control strategies more efficient and cost-effective.

Trawlers intermix with whale ‘supergroup’ in Southern Ocean

Scientists observed close to 1,000 fin whales foraging near Antarctica, while fishing vessels trawled for krill in their midst. Without action, such encounters are likely to become more common as this endangered species recovers and krill harvesting intensifies in the Southern Ocean.

Whales eat colossal amounts of microplastics

Analysis of ocean plastic pollution and whale foraging behavior tracked with noninvasive tags shows whales are ingesting tiny specks of plastic in far bigger quantities than previously thought, and nearly all of it comes from the animals they eat – not the water they gulp.

Mapping risks of labor abuse and illegal fishing

A new modeling approach combines machine learning and human insights to map the regions and ports most at risk for illicit practices, like forced labor or illegal catch, and identifies opportunities for mitigating such risks.
