Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
Strong, durable Martian concrete needs a mix of small-grained Martian sand and pure sulfur. NASA found the ingredients are already there.
It has some researchers taking a second look at other hypotheses that have been proposed — and mostly discarded — in the past.
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.
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?

Blaise Agüera y Arcas argues that function defines life more than material does, and that AI belongs in the same story
Are quantum fields real, or a mere calculational tool? 3 unique experiments show they carry energy. If energy's real, so are quantum fields.
Making more complicated, more precise predictive calculations tells us what real experiments should deliver. AI just surpassed humans at it.

Jennifer Doudna co-invented CRISPR. Now she's the one asking how much power we should be allowed to handle.
The expanding Universe, CMB, and large-scale structure revealed the Big Bang. New nucleosynthesis advances deliver unprecedented precision.
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?
Most time travel stories involve changing the past to create a better future. "Donnie Darko" subverts that expectation, and a whole lot more.
Predicted back in the 1960s, 2012's discovery of the Higgs boson completed the Standard Model. But the biggest Higgs puzzle still persists.
Although many of Einstein's papers revolutionized physics, there's one Einsteinian advance, generally, that towers over all the rest.
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.
From a primordial soup of particles, atoms eventually emerged. What happened to make it so, and could things have worked out any other way?
All matter particles can act as waves, and massless light waves show particle-like behavior. Can gravitational waves also be particle-like?
The matter that creates black holes won't be what comes out when they evaporate. Will the black hole information paradox ever be solved?
In 1982, an experiment showed unprecedented evidence for exotic matter: magnetic monopoles. But without reproducibility, it didn't hold up.
