Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
From the earliest stages of the hot Big Bang (and even before) to our dark energy-dominated present, how and when did the Universe grow up?
Discover how Quantum Bayesianism challenges traditional quantum mechanics by focusing on the role of the observer in creating quantum reality.
This first-of-its-kind image offers a detailed look at the magnetic fields within the Central Molecular Zone.
At a fundamental level, only a few particles and forces govern all of reality. How do their combinations create human consciousness?
A human hand has the power to split wooden planks and demolish concrete blocks. A trio of physicists investigated why this feat doesn’t shatter our bones.

Physicist Sean Carroll on entropy, complexity, and the origins of life:
Dark energy is one of the biggest mysteries in all the Universe. Is there any way to avoid "having to live with it?"
A poignant, 2,000-year-old burial in northern Italy could be the latest evidence of an ancient friendship.
A study of spinal development took a strange turn and made a surprise discovery.
In the 20th century, many options abounded as to our cosmic origins. Today, only the Big Bang survives, thanks to this critical evidence.
"I hope we take a mindset where we are willing to look for weird life in weird places."
For some reason, when we talk about the age of stars, galaxies, and the Universe, we use "years" to measure time. Can we do better?
The JWST's observations of well-developed galaxies early in universal history may coincide with accepted astronomical theory after all.
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.
