Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
Our “embodied minds” suggest an eventual escape from mortality via computer is unlikely.
All telescopes are fundamentally limited in what they can see. JWST reveals more distant galaxies than Hubble, but still can't see them all.
Thanks to the Coriolis force, hurricanes never cross the equator.
There was a time where no starlight was visible throughout the entire cosmos. That time was short-lived: shorter than astronomers imagined.
Hunger rates are rising. These technologies could turn the tide.
Gravitational waves carry enormous amounts of energy, but spread out quickly once they leave the source. Could they ever create black holes?
CERN's NA64 experiment used a high-energy muon beam technique to advance the elusive search for dark matter, offering new hope for solving one of astronomy's greatest mysteries.
The sharpest optical images, for now, come from the Hubble Space Telescope. A ground-based technique can make images over 100 times sharper.
Almost 100 years ago, an asymmetric pathology led Dirac to postulate the positron. A similar pathology could lead us to supersymmetry.
Neuroscientist Christof Koch on human minds, AI, and bacteria.
From the coldest planets to spacecraft that have exited the Solar System, these little-known facts stump even many professional astronomers.
A look back at the rise of solar power in the US and what's next.
The Universe's history, from cosmic inflation to the Big Bang to the present, is known. But whether it's infinite or not is still a mystery.
An excerpt from renowned neuropsychologist Nicholas Humphrey’s book “Sentience: The Invention of Consciousness.”
The future belongs to complexity.
Although the Big Bang occurred at an instant in time long ago, we still see the light from it. Will the evidence ever disappear completely?
"How long someone thinks about [a] problem is a really good proxy of how humans behave."
Known as hypervelocity stars, we originally thought just one would be ejected every 100,000 years. The real number is much greater.
Northern lights in the American South, clusters of huge geomagnetic storms—the Sun is throwing a tantrum right on schedule.
Waistlines are expanding in most countries, except for a skinny list of nations bucking the trend.
