Explainer: How cells use chemistry to make the electricity of life
Charged particles, or ions, constantly move in and out of cells. These migrations produce tiny electric currents, which power your brain, heart and more.

Metal gives the teeth of Komodo dragons their super strength
Investigating Komodo dragons' ironclad teeth in greater detail could also help solve a dental mystery in dinosaurs.

The periodic table might soon have a new element
A new technique could be used to make the undiscovered element 120.

Superman’s kryptonite doesn’t have a true equal on Earth
Though not quite kryptonite, some Earth minerals can glow under ultraviolet light. Excited electrons cause these real-life power stones to light up.

Scientists Say: Goldene
Making this metallic, two-dimensional (2-D) material is difficult — but super-thin sheets of gold could have uses in electronics and chemistry.

Experiment: Make your own cents-able battery
Make your own ‘voltaic pile’ with pennies and nickels, and find out how many coins will make the most electricity!
- Tech
Artificial intelligence helped design a new type of battery
Supercomputing and AI cut the early discovery steps from decades to just 80 hours. The process led to a new solid electrolyte.
- Science & Society
Scientists Say: Model
Models are representations of real-life systems or processes that we use to ask questions, make predictions and test our knowledge.

Chemists make device to destroy planet-warming methane pollution
It can slash diffuse sources of this extremely potent greenhouse gas, such as from livestock barns and other sites.

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.
- Environment
New ultrathin materials can pull climate-warming CO2 from the air
To slow global warming, we’ll need help from CO2-trapping materials. Enter MXenes. They’re strong and reactive — and they love to eat up CO2.

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.
