Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
We're all entitled to our own opinions, no matter how ill-informed they are. But facts are facts; we can't just choose the ones we prefer.
The more you know, the better you can act.
Asteroid 2024 YR4, which could devastate a city's worth of humans, has gone from 1.2% to 2.3% to 2.6% to 3.1% chances of impact. Here's why.
A brief guide to habits that separate deep understanding from superficial knowledge — and how to cultivate them.
At extremely close distances to their stars, even rocky planets can be completely disintegrated. We've just caught our first one in action.
Ring galaxies are rare, but we think we know how they form. A new, early-stage version, the Bullseye galaxy, provides a new testing ground.
New research challenges old assumptions about the evolution of the human brain.
Here in our Solar System, terrestrial bodies get moons from gravitational capture or collisions. The Pluto-Charon system? It was both.
Only 5% of the Universe is made of normal "stuff" like we are. Could there be dark matter or dark energy life, or even aliens, out there?
Timothy Caulfield, a leading science communicator, discusses the challenges of combatting misinformation in an age of information overload.
Could AI develop true intelligence without sentience? Philosopher Jonathan Birch explores the boundaries of artificial and evolved minds.
When we divide matter into its fundamental, indivisible components, are those particles truly point-like, or is there a finite minimum size?
The ultimate multi-messenger astronomy event would have gravitational waves, particles, and light arriving all at once. Did that just occur?
Retrofitting America's aging dams for hydropower — while removing ecologically harmful ones — may be a productive path forward.
A young, nearby, massive star, whose protoplanetary disk appears perfectly edge-on, was just viewed by JWST, with staggering implications.
A new SETI study shows how far the field of technosignatures has come.
Historically, astronomers have often named things creatively, bizarrely, and often inaccurately. But which terms are the most egregious?
The artistic and the mathematical mind are not so far apart.
If we wish to tackle the very real problems society faces, we require expert-level knowledge. Valuing it starts earlier than we realize.
We need to fully acknowledge problems, while vigorously pursuing solutions. Call it “solutionism.”
