Science & Tech

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

space expanding
Yes, the Universe is expanding, but you might wonder, "How fast is it expanding?"
average star
Please stop calling our Sun an "average star." It is philosophically dubious and astronomically incorrect.
mass flourishing
Historically, periods of mass flourishing are underpinned by technological revolutions. Currently, we are undergoing a technological revolution unlike anything the world has ever seen.
asymmetry
The Universe has asymmetries, but that's a good thing. Imperfections are essential for the existence of stars and even life itself.

Researchers have created a method to help workers collaborate with artificial intelligence systems.
nuclear fusion
Why power generated through nuclear fusion will be the future, but not the present, solution to humanity's energy needs.
Milky Way center
As viewed by the MeerKAT telescope, this radio view of the Milky Way blows away every other way we've ever seen our home galaxy.
Jeff Bezos
Altos Labs is an ambitious new anti-aging company with billions of dollars to back it up.
space plane
Space planes could radically lower the cost of spaceflight.
There really might be extraterrestrials out there, attempting to make contact. Here's how science, not fiction, is attempting to find them.
einstein critics
Einstein's theories of relativity faced fierce opposition. One critic claimed he was attempting to subvert the scientific method.
out of africa
A new analysis of an ancient hominin fossil sheds light on the "Out of Africa" dispersal events that occurred more than one million years ago.
Alexa on a pile of books.
The more social behaviors a voice-user interface exhibits, the more likely people are to trust it, engage with it, and consider it to be competent.
parallel universe
In scientific theories, the Multiverse appears as a bug rather than as a feature. We should squash it.
body fat
Scientists at UCLA and Penn argue that malfunctioning fat, not necessarily too much of it, is what makes people metabolically unhealthy.
how many stars
There are ~400 billion stars in the Milky Way, and ~2 trillion galaxies in the visible Universe. But what if we aren't typical?
isaac newton
From physics and alchemy to theology and eschatology, Isaac Newton’s research was rooted in a personal pursuit of the Divine.
history of math
Math offers good evidence that humans can solve any problem — as long as there’s money in it.
