How Scientists Finally Finished the Human Genome
The genomics researcher Karen Miga explains why it’s so important to learn the DNA sequence information buried in parts of our genome that were resistant to scrutiny.
The Missing Link in Artificial Intelligence
Melanie Mitchell, the Davis professor of complexity at the Santa Fe Institute, has worked on digital minds for decades. She says AI will never truly be “intelligent” until they can do something uniquely human: make analogies.
The Standard Model: The Most Successful Scientific Theory Ever
The Standard Model of particle physics is the most successful scientific theory of all time. In this explainer, Cambridge University physicist David Tong recreates the model, piece by piece, to provide some intuition for how the fundamental building blocks of our universe fit together.
The Bridge Between Math and Quantum Field Theory
Nathan Seiberg explains the importance of math in figuring out and understanding the ultimate laws of the universe.
What’s Inside an Exoplanet?

Quantum Computers, Explained With Quantum Physics
Quantum computers aren’t the next generation of supercomputers — they’re something else entirely. Before we can even begin to talk about their potential applications, we need to understand the fundamental physics that drives the theory of quantum computing.
Black Hole Jets: Unraveling One of the Biggest Mysteries in the Universe
At the heart of every galaxy lies one of the most mysterious objects in the universe: a supermassive black hole. Millions to billions of times the mass of our sun, these giants power astrophysical jets, one of the most energetic processes known to physics.
