Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
The most common element in the Universe, vital for forming new stars, is hydrogen. But there's a finite amount of it; what if we run out?
Life arose on Earth very early on. After a few billion years, here we are: intelligent and technologically advanced. Where's everyone else?
Six visionary science fiction authors on the social impact of their work.
Even with the best technology imaginable, you'd probably never be able to exist as a consciously aware brain in a vat.
Total eclipses are a product of a strange and almost eerie cosmic coincidence — one that makes Earth an even rarer world in the galaxy and, by proxy, in the Universe.
Our Universe requires dark matter in order to make sense of things, astrophysically. Could massive photons do the trick?
Vaccines targeting some of our deadliest cancers are showing promise in early trials.
It’s 50% stronger than comparable materials used in aerospace.
Practically all of the matter we see and interact with is made of atoms, which are mostly empty space. Then why is reality so… solid?
Most counties in the U.S. have only one local newspaper, often one that publishes weekly instead of daily.
A recent study suggests that exposure to visual stimuli can diminish the effects of psychedelic drugs.
If the electromagnetic and weak forces unify to make the electroweak force, maybe, at higher energies, something even grander happens?
What would it take to create a truly intelligent microbot, one that can operate independently?
Explore how the study of exoplanets is transforming our understanding of ocean formation.
A physicist, a psychologist, and a philosopher walk into a bar and discuss a framework for thinking better in the 21st century.
The Universe is expanding, and the Hubble constant tells us how fast. But how can it be a constant if the expansion is accelerating?
Here's what recent DESI measurements suggest — and why it's too early to update conventional predictions about the Universe's distant future.
In all the Universe, only a few particles are eternally stable. The photon, the quantum of light, has an infinite lifetime. Or does it?
