One in five galaxies in the early universe could still be hidden behind cosmic...

Astronomers at the University of Copenhagen’s Cosmic Dawn Center have discovered two previously invisible galaxies 29 billion light-years away. Their discovery suggests that up...

X-rays may save Henry VIII’s revered ship, the Mary Rose

The crown jewel of Henry VIII’s 16th century fleet was its flagship, the venerable Mary Rose. More than 500 years after its launch, the vessel...

How ultracold, superdense atoms become invisible

An atom’s electrons are arranged in energy shells. Like concertgoers in an arena, each electron occupies a single chair and cannot drop to a lower...

New breakthrough could help calculate the likelihood of worst-case scenarios

Quick—if you had to guess, what would you think is most likely to end all life on Earth: a meteor strike, climate change or...

New artificial material could sense, decide, and adapt to its environment

Scientists have developed an artificial material called a metamaterial that can respond to its environment, independently make a decision, and perform an action without...

Scientists are a step closer to control 2D graphene

The device you are currently reading this article on was born from the silicon revolution. To build modern electrical circuits, researchers control silicon’s current-conducting capabilities...

How long does a neutron live?

Physicists use "bottle" method to make most precise measurement yet of a neutron's lifetime. Particles called neutrons are typically very content inside atoms. They stick around...

Scientists reveal the nature of unknown gamma-ray sources

Astronomers have unveiled the nature of hundreds of gamma-ray emitting sources, discovering that most of them belong to the class of active galaxies known...

Physicists snap first image of an electron ice

More than 90 years ago, physicist Eugene Wigner predicted that at low densities and cold temperatures, electrons that usually zip through materials would freeze...

How do apples get their distinctive shapes?

Apples are among the oldest and most recognizable fruits in the world. But have you ever really considered an apple’s shape? Apples are relatively spherical except...
