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.
- 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.
- Earth
Scientists Say: Pole
A pole is either of two opposite ends of a molecule, magnet, battery, planet or other object.
- 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.
- 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.
- Chemistry
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.
- Tech
No trees were harmed to 3-D print this piece of wood
How clever! Scientists used print-speed adjustments to control how flat, 3-D printed shapes morph into complex wooden objects.
- Animals
Analyze This: Bulky plesiosaurs may not have been bad swimmers after all
Long-necked plesiosaurs were thought to be slow swimmers. But new research suggests the animals’ large size helped them overcome water resistance.
- Materials Science
Laser light transformed plastic into tiny diamonds
The technique could be used to make nanodiamonds for quantum devices and other technology.
