Positronium

Scientists have created a Bose-Einstein condensate out of excitons — quasiparticles that combine electrons and positively charged "holes" — in a semiconductor. Quasiparticle Bose-Einstein condensates have for six decades been something of a holy grail of low-temperature physics.

Quantum electrodynamics (QED) atoms are composed of unstructured and point-like lepton pairs bound together by the electromagnetic force.

MIT PhD student Magdelena Allen is developing a highly sensitive brain PET scanner that can help answer fundamental questions in both neuroscience and particle physics.

Researchers are finally getting closer to solving "one of the most important problems in physics."

Today's post is for readers with a little science/math background: Last week, I explained, without technicalities, how the various elementary forces of nature can be inferred from the pattern…

A post for general readers: This is the first of several posts celebrating the hugely successful Standard Model of particle physics, the concepts and equations that describe the basic bricks and mo…
