Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.

Raisin bread expanding Universe
Two fundamentally different ways of measuring the expanding Universe disagree. What's the root cause of this Hubble tension?
A group of silver balls resembling mercury surrounding a statue of a man influenced by Maya culture.
Today, many Maya sites are polluted with toxic levels of mercury. The contamination likely originated from cinnabar paints and art.
An image of the earth resonating in space.
The Schumann resonances are the background hum of the entire planet. But they don't affect humans in any way.
Gamma rays in the milky way.
As Marcel Proust said, “The real voyage of discovery… consists not in seeking new landscapes, but in having new eyes.”
A metal railing supporting a white basket.
LK-99, almost certainly, isn't a room-temperature superconductor. The underlying physics of the phenomenon helps us understand why.
atom quantum
The visible Universe extends 46.1 billion light-years from us, while we've probed scales down to as small as ~10^-19 meters.
A black hole in space with a planet in the middle.
How scientists are hearing the gravitational background "hum" of the Universe for the very first time.
Someday, scientists could use stem cells to guide the development of synthetic organs for patients awaiting transplants.
gaia ESA milky way
Einstein's laws of gravity have been challenged many times, but have always emerged victorious. Could wide binary stars change all that?
A man with liver disease is using a nebulizer in a hospital.
A company in England has made a test that picks out the compounds from breath that reveal if people have liver disease.
Earth-like exoplanet
Each of our three nearest stars might have an Earth-like planet in orbit around it. Here's what we'll learn when we finally observe it.
A fish fossil is on display in a museum.
Metaphors like the Great Chain of Being can lead people to misunderstand evolution and humanity’s place in the web of life.
A man with sunglasses and a hat on against a purple background.
Decades of Alzheimer's research might have missed a cellular culprit hiding in plain sight.
superconductor quantum levitation
Is LK-99 truly a room temperature superconductor? These 4 tests, none of which have yet been passed, will separate fact from fiction.
A bottle of pills illustration on a pink background.
The patron saint of calling BS, Harry Frankfurt, died watching his philosophy become more urgent than ever.
Comparison of pain relievers.
Pain relievers like acetaminophen and ibuprofen are made with chemicals derived from oil. Scientists have shown how to make them from trees.
A vintage photograph capturing a couple by a turntable in black and white.
Your heart rate reveals your brain activity, which in turn can predict hit songs — and maybe stock performance, as well.
