The 1,200-year-old “Book of Ingenious Devices” contains designs for futuristic inventions like gas masks, water fountains, and digging machines.

Over time, the Universe becomes less dominated by dark matter and more dominated by dark energy. Is one transforming into the other?

Two fundamentally different ways of measuring the expanding Universe disagree. What’s the root cause of this Hubble tension?

Empty space itself, the quantum vacuum, could be in either a true, stable state or a false, unstable state. Our fate depends on the answer.

Learn to spot the scientists who are searching for the truth rather than money, ego, or fame.

Evolutionary pressures drove the formation of tribes who encoded their values in myths and symbols. Was this cooperation cursed?

Like Mars today, Venus used to be a sci-fi superstar. Recent discoveries could re-ignite our interest in Earth’s “evil twin.”

“Can we push these cells to do something other than what they normally do?” asks developmental biologist Michael Levin. “Can they build something completely different?”

After 15 years of monitoring 68 objects known as millisecond pulsars, we’ve found the Universe’s background gravitational wave signal!

Everything that gets heated up has to, somehow, radiate that energy away. Here’s what we see when that happens in the Universe.

By studying the oldest animals, researchers hope to pinpoint factors affecting human longevity.

This opens the door to manipulating networks of specific neurons.

Don’t worry that your dog’s world is visually drab.

We have long thought that Pluto was completely frozen solid, but the discovery of cryovolcanoes challenges that assumption.

Carnivores, herbivores, omnivores — and now virivores.

Alan Turing and Christopher Strachey created a ground-breaking computer program that allowed them to express affection vicariously when so doing publicly, as gay men, was criminal.

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.

In our common experience, you can’t get something for nothing. In the quantum realm, something really can emerge from nothing.

Epigenetic entropy shows that you can’t fully understand cancer without mathematics.

The dark genome makes up 98% of human DNA. Scientists are just beginning to understand its role in cognitive disorders.

It’s simpler, more compact, and reusable from year-to-year in a way that no other calendar is. Here’s both how it works and how to use it.

Are quantum fields real, or are they simply calculational tools? These 3 experiments show that if energy is real, so are quantum fields.

NuqneH! Saluton! A linguistic anthropologist (and creator of the Kryptonian language, among others) studies the people who invent new tongues.

The new material may make marine uranium extraction economically feasible.

A study involving nearly 2,000 people found links between personality traits and the likelihood of moving toward or away from dementia.

The cause of Alzheimer’s is still not fully understood, but we might be able to vaccinate against it anyway.

The Hyperloop is physically possible, but engineering challenges will make its construction very difficult. Also, accidents would be catastrophic.

The answer may lie in the particular way sand forms on Titan.

Catastrophes are difficult to predict because they are so rare. But AI using active learning can make predictions from very small data sets.

Which is good, because if they do, they violate the cosmological principle. In theory, the Universe should be the same, on average, everywhere. A simulation of the large-scale structure of […]
