Book cover titled "Friction: A Biography" by Jennifer R. Vail, featuring an image of a matchstick angled on a matchbox striker—capturing the spark of friction—set against a light blue background.
The deep study of friction and surfaces — so crucial to industrial manufacture — emerged from a mid-century engineering conference.
graphene atoms
For millennia, diamonds were the hardest known material, but they only rank at #7 on the current list. Can you guess which material is #1?
A person holding a complex metallic lattice structure in focus, with a blurred individual in the background.
It’s 50% stronger than comparable materials used in aerospace.
iron man suit
A unique combination of DNA and silica is the strongest known material for its density (but you’ll need a lot of it before you can build a suit from it).
Two black and yellow strips of string in a plastic container.
You can’t farm spiders — but putting spider genes into silkworms works even better.
A pile of recyclable plastic bottles.
It’s early days, but if the efforts can be efficiently scaled-up, such biological recycling could put a dent in the plastic waste problem.

LK-99, almost certainly, isn't a room-temperature superconductor. The underlying physics of the phenomenon helps us understand why.
superconducting material magnetic levitation
Recent claims put LK-99 as the first room temperature, ambient pressure superconductor ever. Has the game changed, or is it merely hype?

The material is both stronger and lighter than those used to make conventional power plant turbines.
space elevator
But it's still challenging to build a 22,000-mile elevator.
a close up of a red and white shrimp.
The intensely white coloration of the shrimp is a remarkable feat of bioengineering.

The cathedral is being explored as never before.
What if we could harvest energy from human heat, sweat, or vibrations?
3d printing illiustration
Using shaped ultrasound, researchers can 3D print objects in one shot.
An unexpected ancient manufacturing strategy may hold the key to designing concrete that lasts for millennia.
Some solar cells are so lightweight they can sit on a soap bubble.
battery
Lithium-ion batteries pose challenges for our transition toward renewable energy. Sodium-sulfur batteries might be a solution.
top science stories 2022
2022 was another busy year in the realm of science, with groundbreaking stories spanning space, materials, medicine, and technology.
vanadium dioxide
Vanadium dioxide is a strange material that "remembers" information and when it was stored. This is akin to biological memory.
uranium seawater
The new material may make marine uranium extraction economically feasible.
cartilage
The synthetic cartilage was made from cellulose fibers — the stuff found in wood — mixed with a goo called polyvinyl alcohol.
cement
Scientists turn to nature to improve a ubiquitous building material.
graphyne
A two-dimensional material made entirely of carbon called graphene won the Nobel Prize in 2010. Graphyne might be even better.
From Amazon to the US Army, everybody wants one (or 150).
Cement production currently accounts for 8% of global carbon emissions.
