Scientists Say: Proton
These positively charged particles are important building blocks in atoms.

Scientists used lasers to make ‘smoke rings’ of light
Physicists had a bright idea: Make light into swirling, ring-shaped vortices, similar to smoke rings or bubble rings.

You might someday ‘wallpaper’ your bedroom with this loudspeaker
This thin, flexible and lightweight loudspeaker could reduce noise in loud spaces. It also might enable listeners to experience sound in new ways.

When dominoes fall, how fast the row topples depends on friction
Two types of friction help determine how quickly a line of dominoes collapses, computer modeling shows.

Noises sound totally different on Mars than on Earth. Here’s why
The Perseverance rover recorded the sound of laser pulses on Mars. Scientists used those recordings to determine the Martian speeds of sound.

Let’s learn about diamond
Diamond is born under extreme heat and pressure inside Earth and elsewhere in the universe.
- Physics
Scientists Say: Inertia
Inertia is the tendency of objects to resist changes in their motion.

A new clock shows how gravity warps time — even over tiny distances
This clock measured how gravity changes the passage of time in different places — even spots just one millimeter apart.

A star called ‘Earendel’ could be the most distant ever seen
A thin red arc found in an image from the Hubble Space Telescope shows starlight from nearly 13 billion years ago.
- Materials Science
Scientists Say: Silicone
Silicone is a generic term for a whole slew of humanmade polymers with many different forms and applications.
- Archaeology
Muons reveal the inner worlds of pyramids, volcanoes and more
Tracking these subatomic particles can uncover surprising hidden structures.

Gravitational waves ‘kicked’ a newborn black hole across space
Two black holes merged into one, and then sped off at around 5 million kilometers (3.1 million miles) per hour.
