Catching ‘Dory’ fish can poison entire coral reef ecosystems
More than half of saltwater-aquarium fish sold in the United States may have been caught in the wild using cyanide, new data show.

Why some frogs can survive killer fungal disease
A disease is wiping out amphibian species around the globe. New research shows how some frogs develop immunity.
- Animals
Scientists Say: Copepod
Copepods are tiny crustaceans. They eat phytoplankton and float in the water column, although some live in freshwater and on the sea floor.

Spiders eat insects — and sometimes veggies
Plant-eating spiders have been found on every continent except Antarctica, a new study notes.

Parasites give brine shrimp super powers
When infected with parasitic worms, brine shrimp survive better in waters laced with toxic arsenic, a new study finds.

Before eating, Venus flytraps must ‘count’
Researchers find that Venus flytraps respond to the number of times insects touch their sensory hairs. This tells them when it’s time to turn on digestion.

Zika virus raises alarm as it spreads in the Americas
Zika virus has been in Africa and Asia for decades. But is has now spread to the Americas. And it may cause a devastating birth defect.
- Plants
Banana threat: Attack of the clones
Researchers find that disease-causing fungi — all clones of one another — will continue to infect banana plants unless new steps are taken to stop their spread.

Taking attendance with eDNA
Environmental DNA, or eDNA, tells biologists what species are in an area — even when they’re out of sight.

Wildlife forensics turns to eDNA
Environmental DNA, or eDNA, tells biologists what species have been around — even when they’re out of sight or have temporarily moved on.

Explainer: What is anxiety?
Anxiety is the stress linked to worries about an upcoming event — one that may not even happen. But anxiety can affect the body every bit as much as does the stress provoked by staring down a hungry lion.

Humans are ‘superpredators’
A new study compares the hunting habits of wild animals and humans. People, it turns out, are unlike any other predator on Earth.
