Physicists finally calculated where the proton’s mass comes from

A proton’s mass is more just than the sum of its parts. And now scientists know just what accounts for the subatomic particle’s heft. Protons are made up of even smaller particles called quarks, so you might expect that simply adding up the quarks’ masses should give you the proton’s mass. However, that sum is […]

Inside the plans for Chinese mega-collider that will dwarf the LHC

Physicists at Beijing’s Institute of High Energy Physics (IHEP) are are designing the world’s biggest particle smasher. If built, the 100-kilometre-circumference facility would dwarf the 27-kilometre Large Hadron Collider (LHC) at CERN, Europe’s particle-physics laboratory near Geneva, Switzerland — and would cost around half the price. The ambitious 30-billion-yuan (US$4.3-billion) facility, known as the Circular […]

Universal Quantum Phenomenon Found in Superconductors

A ubiquitous quantum phenomenon has been detected in a large class of superconducting materials, fueling a growing belief among physicists that an unknown organizing principle governs the collective behavior of particles and determines how they spread energy and information. Understanding this organizing principle could be a key into “quantum strangeness at its deepest level,” said […]

“Schrödinger’s Bacterium” Could Be a Quantum Biology Milestone

The quantum world is a weird one. In theory and to some extent in practice its tenets demand that a particle can appear to be in two places at once—a paradoxical phenomenon known as superposition—and that two particles can become “entangled,” sharing information across arbitrarily large distances through some still-unknown mechanism. Perhaps the most famous […]

You thought quantum mechanics was weird: check out entangled time

In the summer of 1935, the physicists Albert Einstein and Erwin Schrödinger engaged in a rich, multifaceted and sometimes fretful correspondence about the implications of the new theory of quantum mechanics. The focus of their worry was what Schrödinger later dubbed entanglement: the inability to describe two quantum systems or particles independently, after they have […]

Strange particles coming out of the Earth hint at new physics

Something mysterious coming out of Antartica’sfrozen ground and it could potentially break physics as we know it. According to physicists, it is some sort ofcosmic ray, a high-energy particle that’s blasted its way through space, into the Earth, and back out again.But the particles physicists know about — the collection of particles that make up […]

Swarming Bacteria Create an “Impossible” Superfluid

Researchers explore a loophole that extracts useful energy from a fluid’s seemingly random motion. The secret? Sugar and asymmetry. Outside of the imaginations of physics teachers, frictionless devices are hard to come by. But putting a bunch of swimming bacteria into a drop of water achieves just that: a fluid with zero resistance to motion. […]
