Chemists could replace bubbling flasks with tumbling ball mills.

Steam cars hit the U.S. market in the 1890s but were largely extinct by the 1930s. Will technology bring them back?

Athletes often use creatine to boost performance and aid muscle recovery. Accumulating evidence suggests it could also help with depression.

ATD 2024 challenged us to make moments of recovery part of our daily practice. Here’s how each keynote speaker advised finding that balance.

The Moon is the most likely place for evidence from the dawn of life on Earth to be preserved in cold storage.

Compared to people who took a placebo, the brains of those who took caffeine pills had a temporarily smaller gray matter volume.

Laser-guided lightning systems could someday offer much greater protection than lightning rods.

The Standard Model may or may not be in trouble, but particle physics definitely needs saving. Here’s what the new LHC can do.

The ten greatest ideas in science form the bedrock of modern biology, chemistry, and physics. Everyone should be familiar with them.

Bad news: Sleeping in on the weekends probably won’t cut it.

The intensely white coloration of the shrimp is a remarkable feat of bioengineering.

When stars form, they emit energetic radiation that boils gas away. But it can’t stop gravitational collapse from making even newer stars.

How scientists found out that we live in a cosmic aquarium.

The idea of “absolute time” was our default for millennia. But time is relative, as gravity and motion both cause time to dilate.

The power tower has superior physics but inferior economics.

Astronomers in 2017 caught an image of a supermassive black hole in a galaxy far, far away. Doing it in our own galaxy is a huge milestone.

Featuring SpaceX’s “Mechazilla,” a first-of-its-kind spacewalk, and more.

The Universe certainly formed stars, at one point, for the very first time. But we haven’t found them yet. Here’s what everyone should know.

With a finite 13.8 billion years having passed since the Big Bang, there’s an edge to what we can see: the cosmic horizon. What’s it like?

We don’t need to think about what life is made of but rather what it does.

Time isn’t the same for everyone, even on Earth. Flying around the world gave Einstein the ultimate test. No one is immune from relativity.

Particle physics needs a new collider to supersede the Large Hadron Collider. Muons, not electrons or protons, might hold the key.

∆G = ∆H – T∆S is one of the most abstract formulas in science, but it is also one of the most important. Without it, life cannot exist.

Mark Weinstein outlines a new path for social media that protects, respects, and empowers the regular users.

1.9 billion years ago, a star’s explosive death created a black hole. Its light just arrived at Earth. But did it set a cosmic record?

Who’s afraid of utopia? AI doubters have cold feet. History can warm them.

Every astrobiologist wants to find an alien. But the public should be skeptical when the “aliens” look like tiny humans.

Does Platonic love actually exist?

Desire is like a drug. But is an addict always an addict?

In 1995, Hubble peered at the Pillars of Creation, forever changing our view. Now in 2022, JWST completes the star-forming puzzle.
