Matter and Its Interactions
- Tech
A shape-shifting robotic tooth-cleaner might one day brush for you
A swarm of billions of magnetic, bacteria-killing nanoparticles can be shaped into bristles to fit any surface, including between teeth.
- Chemistry
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.
- Materials Science
These fabrics change color as they stretch
Stretchy, color-shifting cloth may lead to new art, fashions and sensors. A century-old Nobel-prize-winning invention served as its inspiration.

Explainer: What are the different states of matter?
Most people know solids, liquids and gases — but what about the four other states of matter?
- Animals
Sea creatures’ fishy scent protects them from deep-sea high pressures
TMAO’s water-wrangling ability protects a critter’s critical proteins — including muscle — from crushing under deep ocean pressures.

Cosmic timeline: What’s happened since the Big Bang
Energy, mass and the cosmos' structure evolved a lot over the past 13.82 billion years — much of it within just the first second.
- Life
Let’s learn about modern Frankensteins
Modern scientists are creating strange new combinations of living tissue and trying to give dead things new life.

Lego-like way to snap molecules together wins 2022 chemistry Nobel
This so-called ‘click chemistry’ allows scientists to build complex molecules in the lab and in living cells.
- Physics
Experiments on ‘entangled’ quantum particles won the physics Nobel Prize
Three pioneers in quantum physics share the 2022 Nobel Prize in physics.
- Earth
Not one, but two asteroids might have ended the age of dinosaurs
A craterlike structure found off the coast of West Africa might have been formed by an asteroid that struck around the time dinosaurs went extinct.
