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!
- Genetics
Scientists Say: Genetic Engineering
Genetic engineering involves adding, changing or removing certain pieces of DNA from a living thing to give it desired traits.
- Archaeology
A tattoo experiment hints at how Ötzi the Iceman got his ink
The findings challenge a common idea about how the mummified man got marked with dark lines.

Here’s why AI like ChatGPT probably won’t reach humanlike understanding
Unlike people, this type of artificial intelligence isn’t good at learning concepts that it can apply to new situations.
- Materials Science
Scientists Say: Semiconductor
Modern electronics, from cell phones to video games, work thanks to these conductor-insulator hybrids.
- Chemistry
Air pollution can make it harder for pollinators to find flowers
Pollutants that build up in night air can break down the scents that attract pollinating hawkmoths to primrose blooms, disrupting their pollination.
