Physicists record 'lifetime' of graphene qubits

Researchers have recorded, for the first time, quantum coherence of a graphene-based superconducting qubit, meaning how long it stays in superposition to compute with two logical states simultaneously. The work is a key step forward for practical quantum computing.

Why We Still Don't Know How Fast the Universe is Expanding

Behind the astronomical dispute that’s splitting apart the cosmos.

20 Things You Didn't Know About ... The Year in Science

New research saves squishy sea life and explains the “Atacama Alien,” but we still want to know who drilled a hole in a Soyuz spacecraft.

State of Science: Neutrinos Provide a New Way to Probe the Cosmos

Powerful black holes, the solar system, faraway galaxies and more spill their secrets.

State of Science: 11 Biggest Solar System Discoveries of 2018

Thanks to telescopes and probes, our solar system becomes a little less mysterious.

Once More, Into the Unknown

Novelists have "It was a dark and stormy night." For planetary scientists, the equivalent cliche is, "We expect to be surprised." The story of every new space mission seems to begin that way. No matter how intensely researchers study some solar-system object, no matter how they muster the best resources available on Earth, they are inevitably caught off-guard when they get to study it up close for the first time. And no matter how worn and familiar that cliche may sound, it also rings true e

Researchers discover a metamaterial with inherently robust sound transport

Researchers at the Advanced Science Research Center (ASRC) at The Graduate Center of The City University of New York and at the City College of New York (CCNY) have developed a metamaterial that can transport sound in unusually robust ways along its edges and localize it at its corners.

Discovery of topological LC circuits transporting EM waves without backscattering

NIMS has succeeded in fabricating topological LC circuits arranged in a honeycomb pattern where electromagnetic (EM) waves can propagate without backscattering, even when pathways turn sharply. These circuits may be suitable for use as high-frequency electromagnetic waveguides, which would allow miniaturization and high integration in electronic devices such as mobile phones.

Our universe: An expanding bubble in an extra dimension

Uppsala University researchers have devised a new model for the universe – one that may solve the enigma of dark energy. Their new article, published in Physical Review Letters, proposes a new structural concept, including dark energy, for a universe that rides on an expanding bubble in an additional dimension.
