Ecosystems: Interactions, Energy, and Dynamics
- Brain
To protect kids, get the lead out!
Lead poisons hundreds of thousands of children. In Chicago, experts show how the toxic metal hurts test performance in school.
- 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.
- Health & Medicine
How this vitamin can foster pimples
Oh no! Vitamin B12 can cause skin bacteria to secrete chemicals that cause zits.
- Animals
Biowarfare saves bats from killer fungus
Good news for bats. Those infected with white-nose syndrome may be cured by a brief exposure to fumes from therapeutic bacteria.
- 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.
- Tech
This door handle kills germs
A high-tech door handle may cut down on disease transmission, say its teen developers. The system is powered by simply opening and closing the door.
- Ecosystems
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.
- Microbes
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.
- Plants
Picture This: The world’s biggest seed
This monster seed develops on a super-slow-growing island palm. Key to that palm’s survival are leaves that funnel fertilized water to nutrient-starved roots.
- Animals
Pesticides offer bees a risky allure
Honeybees and bumblebees sometimes cannot taste or avoid pesticides called neonicotinoids. And that may expose some of these important pollinators to harm.
- Animals
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.
