Let’s learn about the weird science of ice
Better understanding of ice could lead to new deicing materials or even, someday, weather control.
- Tech
New robot can pick up a single drop of liquid
The new device, which looks like a pair of plastic pinchers, is the first to be able to pick up individual droplets of liquid.

Scientists Say: Hydrogel
Tangled polymer chains help hydrogels hold their shape despite being full of water.
- Chemistry
Scientists Say: Fluorescence
This property causes materials — including some animals’ skin, fur or feathers — to glow under light.

Explainer: What is a hydrogel?
These unusual materials have a host of unusual properties. You can even make a starch-infused version in your kitchen.

Let’s learn about microplastics
Microplastics have turned up everywhere from the highest mountains to the bottom of the ocean — and even inside animals and people.

Could we make vibranium?
The ‘perfect’ metal may belong to the fictitious Marvel world of Wakanda, but scientists hope to one day mimic some of its key traits.
- Physics
Scientists Say: Neutron
Neutrons are one of the main building blocks of atoms and have no electric charge.
