What Could Explain the Gallium Anomaly?

Around 6,000 years ago, the Sahara was a lush grassland. Then, as if a switch flipped, it began to dry out, becoming the desert that we know today. Tipping points are moments in Earth’s history where gradual change suddenly becomes rapid and forms a new equilibrium.They’re one of ... Show More

It’s been difficult to find important questions that quantum computers can answer faster than classical machines, but a new algorithm appears to do it for some critical optimization tasks.The story Quantum Speedup Found for Huge Class of Hard Problems first appeared on Quanta Mag ... Show More

“Memory” means many things to many people, and in many fields. We tend to understand memory to be a phenomenon that happens primarily in the brain, but in recent years, researchers have understood memory as a physical phenomenon that can occur in plenty of systems. On this episod ... Show More

Dark energy, the mysterious force powering the expansion of the universe, appears to be weakening over time, according to a major cosmological survey that has thrown the laws of modern physics into doubt. Ian Sample tells Madeleine Finlay how this new finding could shed light on ... Show More

Imaginez un univers où tout ce que nous voyons — les étoiles, les planètes, les objets autour de nous — est fait de minuscules particules appelées électrons. Ces électrons sont des composants essentiels de la matière, et ils ont tous des propriétés identiques : même charge électr ... Show More

As an experimental facility, the Large Hadron Collider at CERN in Geneva has been extraordinarily successful, discovering the Higgs boson and measuring multiple features of particle-physics interactions at unprecedented energies. But to theorists, the results have been somewhat f ... Show More
