Researchers Reveal the Power of ‘Quantum Proofs’
When checking that solutions to certain problems are correct, it turns out, you can’t get around the inherent complexity of the quantum world.
Astrophysicists Puzzle Over Webb’s New Universe
Faced with observations of early black holes and galaxies that weren’t expected to exist, scientists have come up with a wealth of new theories to explain them. Now they just need to figure out which ones are true.
For the First Time, a Cell Built From Scratch Grows and Divides
Scientists built a synthetic cell that combines more lifelike properties than ever before — proof of concept that it’s possible to bring nonliving materials to life, or something close to it, in the lab.
What Breaks a Cell’s Ribs Can Make It Stronger
The mechanical process of cell division exerts powerful, if microscopic, forces. How do the molecular machines that power it manage the strain?
After 80 Years, Mathematicians Give Famed ‘Erdős Method’ an Upgrade
Decades ago, Paul Erdős used randomness to illuminate the vast and weird world of networks. Now mathematicians are making his technique even more powerful.
What Is the Positive Grassmannian and Why Does It Show Up Everywhere?
Lauren Williams tells 'The Joy of Why' how studying a fundamental object in algebraic combinatorics led to a career full of surprises.
How Physicists Track and Trap the Elusive Neutrino
The hunt for these ghostly particles has required some of the most audacious experimental setups ever built.
A Dark Dimension Could Link Two of the Universe’s Great Unknowns
Recent observations suggest that dark energy is changing over time. Theorists wonder if dark matter is, too.
Why the Human Genome’s Tangled Physicality May Confound AI
Our genetic heritage is not a blueprint or an algorithm, as many biologists have imagined, but something else entirely.
