Colorado deluge produced flood of drug-resistance genes
Flooding in Colorado’s South Platte River Basin washed antibiotics and drug-resistance genes into pristine waterways.
- Archaeology
Feedback
Readers ask questions about a study on sweeteners, how scientists recognize primitive tools and the purpose of a dinosaur's sail.
- Environment
Spiders enlisted as pollution sensors for rivers
Hunting arachnids provide a better picture of chemical threats to food web.
- Animals
Ant colonies prefer homes infected with fungus
Choosing a new nest site ridden with a potentially deadly fungus may be a way for pharaoh ants to immunize themselves against the pathogen, scientists say.
