Science & Tech

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

Close-up of a rough rock surface with brown and green mineral fragments scattered and embedded within darker matrix material.
Strong, durable Martian concrete needs a mix of small-grained Martian sand and pure sulfur. NASA found the ingredients are already there.
A steaming, rocky geothermal crater with mineral deposits, surrounded by barren, yellowish terrain under a cloudy sky.
It has some researchers taking a second look at other hypotheses that have been proposed — and mostly discarded — in the past. 
olympus mons
From base to tip, Mars's Olympus Mons is the highest known mountain in the Solar System. Evidence suggests a higher one could be out there.
black hole
From Hawking radiation, even black holes are expected to eventually decay. Do they ever reach a point where we'll see what's inside of them?
A man in black clothing sits on a stool in front of a white backdrop in a modern, bright room with large windows and minimal decor.

Blaise Agüera y Arcas argues that function defines life more than material does, and that AI belongs in the same story
entanglement across space
Are quantum fields real, or a mere calculational tool? 3 unique experiments show they carry energy. If energy's real, so are quantum fields.
3D geometric shape with colored edges and yellow triangular faces, appearing as a complex polyhedron on a black background—reminiscent of structures often explored in AI breakthrough research and theoretical physics.
Making more complicated, more precise predictive calculations tells us what real experiments should deliver. AI just surpassed humans at it.
A woman with gray hair in a bob, wearing a beige blazer and gold necklace, sits against a plain white background, looking slightly upwards with a neutral expression.

Jennifer Doudna co-invented CRISPR. Now she's the one asking how much power we should be allowed to handle.
evolution of the Universe from all free particles to stable atomic nuclei to neutral atoms
The expanding Universe, CMB, and large-scale structure revealed the Big Bang. New nucleosynthesis advances deliver unprecedented precision.
Voyager 1
We strongly suspect we aren't alone in the Universe, but so far, we haven't found anyone. What determines when we'll finally make contact?
A page titled “The Philosophy of Time Travel” and a folded paper with a sinister, smiling skull drawing are set against a geometric, tunnel-like background, alluding to the mysterious lessons in physics and mortality found within Donnie Darko.
Most time travel stories involve changing the past to create a better future. "Donnie Darko" subverts that expectation, and a whole lot more.
standard model color
Predicted back in the 1960s, 2012's discovery of the Higgs boson completed the Standard Model. But the biggest Higgs puzzle still persists.
Einstein field equations
Although many of Einstein's papers revolutionized physics, there's one Einsteinian advance, generally, that towers over all the rest.
crab pulsar remnant
Millisecond pulsars are the Universe's most accurate natural clocks. A pulse change, thought rare, just occurred twice in the closest one.

Tech journalist Joanna Stern spent a year using as many AI products as she could. It changed more than her workflow.
A colorful, abstract scientific illustration with a central glowing sphere, circular patterns, and various lines and circles suggesting quantum connections or uncertainty data points, on a dark background with blue accents.
From a primordial soup of particles, atoms eventually emerged. What happened to make it so, and could things have worked out any other way?
colliding black holes
All matter particles can act as waves, and massless light waves show particle-like behavior. Can gravitational waves also be particle-like?
black hole hawking
The matter that creates black holes won't be what comes out when they evaporate. Will the black hole information paradox ever be solved?
A person in a cleanroom suit stands next to a large cylindrical scientific instrument inside a high-tech laboratory with bright lighting and metallic walls, where one blip of dark matter was recently detected.
In 1982, an experiment showed unprecedented evidence for exotic matter: magnetic monopoles. But without reproducibility, it didn't hold up.

Until recently, nobody had visualized the fungal "Wood Wide Web."
