Experiments explain how DNA strands can be captured at their extremities by nanoscale pores.

Previously observed convection in granular materials is now shown to be driven in part by the force of gravity, according to new microgravity experiments.

Muon capture experiments provide a rare opportunity to measure the effects of quark interactions in the proton.

Radiative heat transfer usually increases at shorter separation distances, but new calculations describe micron-scale cases where less heat is exchanged as two objects approach.

Relativistic electrons passing through a laser-produced plasma map out magnetic fields that move at nearly the speed of light.

Light stored in a Bose-Einstein condensate can be manipulated with light to create an optical AND gate.

Flagella on the surface of a multicellular alga can beat in an unexpectedly synchronized fashion.

Cosmic gamma-ray bursts turn out to be polarized, which rules out the breaking of a fundamental symmetry down to the lowest limits ever observed.

Finding the most energetically favorable crystal structure of closed-shell atoms is a long-standing problem where experiment and theory don’t agree, but a study of argon nanoclusters is providing new insight into the discrepancy.

Glitches in the rotation of pulsars cannot be explained by the conventional model of superfluid neutrons beneath the star’s crust.

A nanowalker made of DNA moves along biomolecules without chemically altering them.

Photoemission experiments put new constraints on the pairing mechanism in iron-based superconductors.

Quantum Hall effects can be exploited to tune, reverse, and even eliminate the Casimir force between two graphene sheets.

Field patterns produced near nanoparticles could allow closely spaced traps for ultracold atoms.

Three major drawbacks to the ΛCDM dark matter model of the universe may be ameliorated if a proposed particle couples to dark matter and to neutrinos.

Surface-sensitive spectroscopy reveals the microscopic structure of the water-vapor interface and its dependence on nuclear quantum effects.

A new way of topologically labeling the pasta phases thought to exist in neutron stars could help researchers sort out how the phases contribute to star cooling.

Individual neutral atoms trapped in optical tweezers have been cooled to their quantum ground state, raising hopes that they can be used to process quantum information.

In laser metrology, adding additional laser pulses, separated in time from the first, suppresses energy line shifts and allows for even more precision.
