Keeping samples cool without electricity
When vaccines and blood get too warm or cold, they can become useless. Two teens invented ways to keep their temperatures just right, no matter where they are.
- Life
Scientists Say: Strain
These are organisms that belong to the same species, but have definable differences.
- Animals
Insects can patch their broken ‘bones’
When insects suffer wounds, they can mend their ‘skeleton’ with a patch on the inside. This makes the leg strong again, new data show.

Help us fund the Eureka! Lab video series
I want to make a video series that turns demonstrations into real experiments. But to do it, I need your help.
- Ecosystems
Scientists Say: Vector
Vectors are used to transfer things. Sometimes the transferred item is a disease, but scientists can also use vectors to insert helpful genes.
- Physics
Scientists Say: Frequency
The distance between one wave peak and another is wavelength. But how fast those peaks are moving along is frequency.
-
A paper microscope magnifies on the go
Classroom microscopes can be clunky and costly. An inventor has designed one so small, tough and cheap that it can go home in every kid’s backpack.
- Physics
Scientists Say: Yottawatt
On Earth, scientists measure energy use in watts. When you have lot of those watts — one million billion billion — you have a yottawatt.

Sewing circuits: A crafty way to get kids interested in STEM
Many classrooms teach electric circuits with batteries and wires. But with e-textiles, students can help design and light up their own art projects.
- Physics
Scientists Say: Wavelength
When something travels as a wave — such as light — scientists can measure it by its wavelength, the distances between the peaks.
- Physics
Scientists Say: Watt
Say Watt? This is a unit used to measure the flow of energy being used.
- Math
Scientists Say: Y-axis
The bars on a graph tell you nothing unless you know what they mean. The lines on the sides can let you know.
