Behold the world’s thinnest pasta
Made from white flour and formic acid, the nanofibers average just 370 nanometers across. That’s two-hundredths the thickness of a human hair.

Weirdly, mayo can help study conditions ripe for nuclear fusion
Yes, mayo. The texture of the sandwich spread is perfect for mimicking what a fusion fuel capsule goes through when blasted with lasers.

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.

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.

Turning jeans blue with sunlight might help the environment
When dipped in indican and exposed to sunlight, yarn turns a deep blue. This process is more eco-friendly than the current denim dyeing method.
- Physics
Forests could help detect ‘ghost particles’ from space
If trees could act as natural antennas, one physicist proposes that they just might pick up signals of hard-to-spot ultra-high energy neutrinos.
- 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.

9 things to know about lead’s health risks — and how to curb them
Lead has been linked to lower IQ, behavior problems, mental-health disorders, strokes and more health impacts. There are ways to reduce your exposure.
- 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.
