Science & Tech

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

cgi
Technologically, the answer is definitely no. But that doesn't mean CGI is always used to good effect.
superconductors
In a major advance, scientists have found a new and groundbreaking way to force electrons to flow only in one direction in a superconductor.
statins
A doctor once joked that statins will be added to the water supply. Humor aside, the data shows that statins really are a "wonder drug."
galaxy cluster colors
Over time, the Universe becomes less dominated by dark matter and more dominated by dark energy. Is one transforming into the other?
An effect called the "urban heat island" means that temperatures are often 10 degrees higher in cities, according to NASA.
hyperloop
The Hyperloop is physically possible, but engineering challenges will make its construction very difficult. Also, accidents would be catastrophic.
Hyperloop
The hyperloop would be a great idea for a completely flat planet. With topography and infrastructure, it's a very different story.
"The pulsar sort of consumes the thing that recycled it, just as the spider eats its mate.”
biological age
Your old-fashioned chronological age is just a number. Your biological age can tell you how healthy you really are.
big crunch
13.8 billion years ago, the hot Big Bang gave rise to the Universe we know. Here's why the reverse, a Big Crunch, isn't how it will end.
Now they're pointing the way to future battery technologies.
atom
Atomic clocks keep time accurately to within 1 second every 33 billion years. Nuclear clocks could blow them all away.
But does Amazon know when you're tired or hungry?
What you need to know about this smallpox cousin.
Voyager 1
In all of human history, only 5 spacecraft have had the right trajectory to exit the Solar System. Will they ever catch Voyager 1?

Data from the Zhurong rover suggests the Red Planet was wet more recently than we thought.
