A third category of quantum particle has been identified, metal objects placed in superposition, and quantum encryption proved at 120km range — all in one week. Plus, why blood viscosity may be the key to understanding why the universe is fine-tuned for life.

A new study has landed squarely in the middle of one of physics' oldest arguments: why does the universe appear so precisely calibrated for life to exist? The answer, at least partly, may come down to something as ordinary as the thickness of blood.
Moving to a finding that could reshape fundamental physics, a discovery published on May ninth has identified a new category of quantum particle. For seventy years, the classification system governing all known matter divided particles into two types: fermions and bosons.
On May eleventh, an experiment pushed quantum weirdness into territory most physicists considered far off. Metal particles containing thousands of atoms were placed into quantum superposition, meaning they existed in multiple locations simultaneously.
The race to build a genuinely unhackable communications network hit a practical milestone on May ninth. Using semiconductor quantum dots, researchers demonstrated stable quantum key distribution across one hundred and twenty kilometers of optical fiber.
Three other developments round out the week. On April thirtieth, a quantum state was teleported two hundred and seventy meters between independent quantum dots in open air, which is a meaningful step for building distributed quantum networks.
The thread connecting all of this is acceleration. Quantum communication, quantum matter, and the fundamental physics of why anything exists at all are moving faster than the field expected.
