Metal hydride molecule trapped with laser light opens path to ultracold hydrogen
Controlling and trapping molecules, units of a substance consisting of two or more chemically bound atoms, with laser light is significantly more challenging than trapping individual atoms. This is because molecules exhibit ...
Scientists measure hidden quantum forces that could power a new generation of pharmaceutical drugs
It's one thing to design a pharmaceutical drug. It's another to know if and why it actually works; not on paper or in a computer model, but inside the chaotic world of living systems, where proteins twist into shape, atoms ...

A thermodynamic approach to gravity could explain cosmic acceleration without dark energy
Gravity, the force that attracts objects toward each other, is currently framed by Albert Einstein's theory of general relativity. This framework describes gravity as the curvature of spacetime, the invisible four-dimensional ...
Quantum waves reveal one-sided motion marking elusive critical states
Sound waves, light waves and other types of waves, generally spread freely through space and over time. In 1958, physicist Philip W. Anderson first described a phenomenon via which irregularities or other sources of disorder ...
A new quantum computer sets a high watermark for accuracy. Are we on the verge of a big breakthrough?
In a laboratory in Broomfield, Colorado, 98 atoms are suspended in midair, held in place by electric fields and cooled to temperatures close to absolute zero.
