Pollution power? A new device turns carbon dioxide into fuel
Scientists made a device that converts the greenhouse gas into formate. This salt can then run a fuel cell to make electricity.

Explainer: The hydrogen rainbow
Hydrogen works the same, regardless of its source. But how clean or “green” it is very much hinges on its color-coded name — which points to how it was made.

Hydrogen energy could help our climate — depending on its source
Hydrogen energy doesn’t emit greenhouse gases when it’s used. But how it’s produced will affect how useful it can be in slowing climate change.

Scientists turn plastic wastes into soap
Chemists developed a way to turn plastic waste into surfactants. Those chemicals could one day become key recruits in a greener war on grime.

Experiment: Kimchi chemistry
In this cooking and food science project, we make kimchi from scratch and investigate changes in pH and glucose as it ferments.

Scientists Say: PFAS
Non-stick coatings, stain-resistant cloth and other common materials leach long-lived PFAS into soil and water.

Rare-earth mining is dirty but key to a climate-friendlier future
That’s spurring new research to find a steady but safer supply of these precious metals, including in the United States.
- Animals
These beetles ‘drink’ water using their butts
Red flour beetles can survive in very dry environments. New research shows how the beetles can suck water from the air using their rear ends.

Minding your mummies: The science of mummification
In this science project, you will learn about the rituals and science of mummification by mummifying a hot dog.

Let’s learn about the weird science of ice
Better understanding of ice could lead to new deicing materials or even, someday, weather control.

Does the size of a parachute matter?
How does a parachute work? Do bigger parachutes work better than smaller parachutes? Find out in this science project whether the size of the parachute matters.

Scientists Say: Neutron
Neutrons are one of the main building blocks of atoms and have no electric charge.
