Matter and Its Interactions
- Chemistry
The periodic table might soon have a new element
A new technique could be used to make the undiscovered element 120.
- Earth
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.
- Materials Science
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.
- Chemistry
Scientists Say: Excitation
Excited electrons are to thank for dazzling fireworks displays, plants harnessing energy, the semiconductors behind modern tech and more.
- Materials Science
New lab trick makes diamonds without extreme pressure
The lab-grown diamonds form in a liquid of gallium, iron, nickel and silicon.
- Chemistry
Scientists Say: Methane
Used to cook food and heat homes, this potent greenhouse gas accounts for 30 percent of the warming of our climate.

Bioelectronics research wins top award at 2024 Regeneron ISEF
Three grand-award winners each took home at least $50,000. Hundreds more teens shared more than $9 million in prizes at the international competition.
- Environment
To limit pollution, new recipe makes plastic a treat for microbes
Microplastics made from fossil fuels take centuries to disappear. But the plant- and algae-based plastic can break down in weeks to months.
- Tech
Lego bricks inspired a new way to shape devices for studying liquids
Inspired by Lego building blocks, the approach could enable design of adaptable tools to study how fluids move through very small spaces.

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!
- Materials Science
Scientists Say: Semiconductor
Modern electronics, from cell phones to video games, work thanks to these conductor-insulator hybrids.
