With the invention of the leap year, the Julian calendar was used worldwide for over 1500 years. Over time, it led only to catastrophe.
Earth wasn't created until more than 9 billion years after the Big Bang. In some lucky places, life could have arisen almost right away.
The first-of-its-kind map, which goes all the way down to the level of a single cell, could help prevent common birth defects.
A basement renovation project led to the archaeological discovery of a lifetime: the Derinkuyu Underground City, which housed 20,000 people.
As wind power grows around the world, so does the threat the turbines pose to wildlife. From simple fixes to high-tech solutions, new approaches can help.
Even after the first stars form, those overdense regions gravitationally attract matter and also merge. Here's how they grow into galaxies.
Teller and Sagan debated fiercely over nuclear proliferation. But was the conflict as personal as it was intellectual for Teller?
When battles raged in ancient cities, their rocks blazed so brightly that they could be reoriented according to Earth's magnetic field.
Frontier, the ORNL supercomputer, used machine learning to perform 9.95 quintillion calculations per second.
The first stars took tens or even hundreds of millions of years to form, and then died in the cosmic blink of an eye. Here's how.
From how life emerged on Earth to why we dream, these unanswered questions continue to perplex scientists.
The first tests of optical communications far from Earth will take place aboard the asteroid-bound Psyche spacecraft
Kent Keirsey, CEO of Invoke AI — an open-source creative engine — outlines the pros and cons of open-source and closed-source AI tools.
The Universe is an amazing place. Under the incredible, infrared gaze of JWST, it's coming into focus better than ever before.
Physicists have yet to pinpoint the hypothetical matter that keeps galaxies from flying apart. Now they have a new focus.
In pre-War Cambridge, students had to ace an interview with Ludwig Wittgenstein to attend his lectures — Alan Turing passed that test, and went on to create one of his own.
As Uranus approaches its solstice, its polar caps, rings, and moons come into their best focus ever under JWST's watchful eye. See it now!
Thanks to observations of gravitational waves, scientists were able to settle a longstanding debate over the speed of gravity.
Misinformation was extremely popular in 2023, as bad science often made global headlines. Learn the truth behind these 10 dubious stories.
The problem with today’s AI isn’t it thinking for itself; it’s the tech telling humans whatever we want to hear.
These theoretical megastructures represent one way an advanced civilization might harvest energy from stars.
In our Universe, matter is made of particles, while antimatter is made of antiparticles. But sometimes, the physical lines get real blurry.
