In our Universe, all stable atomic nuclei have protons in them; there’s no stable “neutronium” at all. But what’s the reason why?

Many people lived long enough to grow old in the olden days, too.

You can lead an overconfident chatbot to expert knowledge, but can it actually learn and assimilate new information?

The four-color theorem was one of the past century’s most popular and enduring mathematical mysteries.

How our brains interpret computer code could impact how we teach it.

If our Universe were born a little differently, there wouldn’t have been any planets, stars, galaxies, or chemically interesting reactions.

From hellishly hot planets to water worlds, some distant planets are like nothing in our Solar System.

There are many problems with relying on SAT and ACT scores for college admissions. But removing them entirely creates less opportunity.

Achieving values and pursuing growth is the real secret to a fulfilled life.

Protons and neutrons are held together by the strong force: with 3 colors and 3 anticolors. So why are there only 8 gluons, and not 9?

A group of prominent scientists shares how research has changed them.

Leading a scientific revolution is easy: you just have to succeed where the current theory fails while equaling its successes. Good luck!

Yes, “the laws of physics break down” at singularities. But something really weird must have happened for black holes to not possess them.

Science doesn’t fit neatly into ideology.

A cute mathematical trick can “rescale” the Universe so that it isn’t actually expanding. But can that “trick” survive all our cosmic tests?

Research suggests that emotional intelligence is more vital for success than IQ.

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

We confidently state that the Universe is known to be 13.8 billion years old, with an uncertainty of just 1%. Here’s how we know.

American students are being compelled to specialize earlier and earlier. Here’s what it takes to build a successful physics foundation.

Women have made incredible gains into STEM fields, but they continue to face gender biases in the workplace.

Awe-inspiring moments can be found in our daily lives, and they have surprising benefits for our health and sense of well-being.

The “Foundation” series, recently adapted into a show by Apple TV, was inspired by a fascinating, real-life academic discipline.

Real-time online learning is where our dated education system is heading.

This everyday electrical phenomenon had no widely accepted scientific explanation — perhaps, until now.

Singularities frustrate our understanding. But behind every singularity in physics hides a secret door to a new understanding of the world.

“At that time, it was just a wild idea, […] that instead of just a loss of consciousness, anesthetics may do something to the brain that actually turns pain off.”

If measuring eLearning ROI is so important, why aren’t more organizations doing it?

Elastic thinking can reveal the assumptions that hamstring our ability to solve seemingly intractable problems.

Short-termism is both rooted in our most primal instincts and encouraged by runaway technological development. How can we fight it?

Measurements of the acceleration of the universe don’t agree, stumping physicists working to understand the cosmic past and future. A new proposal seeks to better align these estimates — and is likely testable.
