Matter and Its Interactions
- Chemistry
Experiment: What makes ice melt fastest?
During the winter, you might have seen trucks spreading a mix of salt and sand on the roads to de-ice them. But how does that work? Let’s investigate.
- Materials Science
Scientists Say: Quantum dot
Quantum dots are nanosized specks whose properties are governed by the strange rules of quantum physics.
- Physics
Let’s learn about entanglement
Entanglement is a special connection between particles that syncs up their properties — even when the particles are far apart.

Explainer: How cells use chemistry to make the electricity of life
Charged particles, or ions, constantly move in and out of cells. These migrations produce tiny electric currents, which power your brain, heart and more.
- Physics
Weirdly, mayo can help study conditions ripe for nuclear fusion
Yes, mayo. The texture of the sandwich spread is perfect for mimicking what a fusion fuel capsule goes through when blasted with lasers.
- Health & Medicine
Scientists Say: THC
The active chemical in marijuana might have some medicinal value. But studies point to THC's potential risks, especially for teens.
- Health & Medicine
Skin appears to be no barrier for some common ‘forever’ chemicals
These PFAS, which have been linked to health problems, show up in many products that we touch every day — including clothes and food packaging.
- Climate
Stashing more CO2 in the ocean could slow climate change
More research is needed on ways to safely remove some CO2 from the water to make room for more — such as by seaweed farming and iron fertilization.
- Animals
Metal gives the teeth of Komodo dragons their super strength
Investigating Komodo dragons' ironclad teeth in greater detail could also help solve a dental mystery in dinosaurs.
- Chemistry
The periodic table might soon have a new element
A new technique could be used to make the undiscovered element 120.
- Earth
Superman’s kryptonite doesn’t have a true equal on Earth
Though not quite kryptonite, some Earth minerals can glow under ultraviolet light. Excited electrons cause these real-life power stones to light up.
- Materials Science
Scientists Say: Goldene
Making this metallic, two-dimensional (2-D) material is difficult — but super-thin sheets of gold could have uses in electronics and chemistry.
