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.

Wolves beat dogs at problem-solving test
When treats are at stake, wolves outperformed dogs at opening a closed container. The dog’s relationship with humans may explain why.
- Agriculture
Organic food starts to prove its worth
Organic food often comes with a higher price. But research is showing that food grown this way can be better for the environment — and possibly for us.
- Computing
These young scientists are passionate about tech and math
The 2015 Broadcom MASTERS International delegates show why math and computer skills are key to the success of science-fair projects.
- Plants
Using plants to solve environmental problems
Problems in their communities suggested good research projects to three teens. Each wanted to tackle a different issue, from pollution to world hunger. To learn more about these issues, they turned to their local ponds, wetlands and gardens.

Scientists Say: Taphonomy
Studying what happens to plants and animals after they die can teach us about ecosystems and evolution. This study has a special name.
- Animals
The bugs within us
Hordes of bacteria live inside people and other animals. This ‘microbiome’ can affect the development of the blood-brain barrier, food choices — even mating.

Scientists feed bed bugs (on purpose)
To study bed bugs in the lab, scientists had to first learn how to keep the blood-thirsty critters well fed. And that proved easier said than done.

What’s for dinner? Mom.
Female spiders of one species make the ultimate sacrifice when raising their young: The mothers feed themselves to their children.
