From an echo to a seafloor map
Multibeam sonar measures depth and returning sound strength. Survey routes, corrections and targeted photographs turn those measurements into a map worth investigating.

Why lake-effect snow can bury one place and miss its neighbor
A narrow snow band draws warmth and moisture from open water. Its route determines both where that supply comes from and where the snow lands.
The lava river that builds its own roof
A lava tube begins as a route for moving molten rock. Its roof, walls and hanging formations preserve different parts of that journey.
How a tree keeps its structure while becoming stone
Burial and mineral-bearing water help preserve the wood’s internal architecture. The colors and apparently sawn ends tell other parts of the story.
How to read a record from an unfamiliar world
The Golden Record’s cover connects a needle, a recorded signal and a set of pictures—and gives a recipient ways to work out where the message began and how much time has passed.
How a moving planet gives a spacecraft a boost
Voyager left Jupiter with the same Jupiter-relative speed it had on arrival. Yet measured relative to the Sun, it gained speed. The difference lies in direction—and in Jupiter’s own motion.
Why floating ice stays mostly underwater
Freezing spreads water molecules apart. The resulting density difference lets ice float—but leaves most of its volume below the surface.
Why a harder mortar can hurt an old brick wall
A Missouri basement shows how mortar protects historic masonry—and why finding a compatible replacement begins with reading the material already there.
Why a blocked nose can take the flavor out of dinner
Aromas reach your nose from inside your mouth as you chew. Following that route explains why food can seem bland during a cold—and how taste, smell, temperature and texture create a recognizable mouthful.
Saving sunshine for the hour everyone gets home
The duck curve reveals a timing problem: solar production fades as evening electricity needs rise. Storage can bridge that gap, but the amount it holds and the speed it releases energy both matter.
Why NIST urged a head start on quantum-resistant encryption
A look back at the August 2024 standards: what the three tools are for, and why being ready to use them was only the beginning of the work.
What Pluto’s orbital rhythm tells us about the worlds beyond Neptune
The Kuiper Belt holds remnants of the solar system’s beginnings. Their paths around the Sun help astronomers distinguish ancient stability from the effects of Neptune’s gravitational reshuffling.

The animal that edits its own skin.
A disappearing octopus is doing several jobs at once: resizing patches of pigment, working with reflected light and reshaping the surface of its body.
Glass is not another word for clear.
A diamond and a window can both let you see through them. That tells you surprisingly little about how their atoms are arranged.
A grain of sky. Thousands of galaxies.
Historical edition · July 2022. Webb’s first deep field is a crowded view, a record of old light and a demonstration of how instruments turn measurements into an image.
Before the beater falls.
A Han entertainer's raised hand gives us a place to look—and a reason to leave the lost performance open.
Before blue was a colour, it was a journey.
A blue robe can hold a mineral’s history, a painter’s technique and evidence too small to see from the gallery floor. Start with Raphael’s Ansidei Madonna.
Earth made a mixtape. Then sent it away.
The 1977 Voyager Golden Record joins an impossible editorial brief with a practical engineering problem: choose a planet’s introduction, then explain how a stranger might play it.
