The race for realizing Majorana fermions—elusive particles that act as their own antiparticles—heats up, but we still await ideal materials to work with.

Scanning tunneling microscopy experiments in a high-temperature superconductor probe the temperature evolution of local electronic states, revealing that regions in the sample exhibiting weak superconductivity can persist to elevated temperatures if they are surrounded by regions of strong superconductivity.

New measurements with the Fermi Large Area Telescope extend our knowledge of the extragalactic diffuse gamma-ray background and may help resolve the question of its origins.

The transmission of light through a disordered medium is described in microscopic detail by a high-dimensional matrix. Researchers have now measured this transmission matrix directly, providing a new approach to control light propagation.

A single $30$-femtosecond pulse has been used to observe x-ray diffraction of a magnetic material, potentially opening the way to ultrafast probing of spin dynamics with nanometer spatial resolution.

Thermal magnetic fluctuations, usually thought of as a barrier to magnetic information storage and processing, can be harnessed to make green, low-energy magnetic applications a possibility.

Experiments now quantitatively confirm the standard model of electrokinetics, in which electric fields drive the flow of electrolytes, potentially leading to better sensors and biomedical diagnostic devices.

Two groups have made progress in building laserlike devices that emit phonons rather than photons.

The observation of a strong nonlinear diamagnetic signal well above $T_c$ in several cuprate superconductors constitutes clear evidence of the persistence of local superconducting correlations.

The two experimental collaborations at the Fermilab Tevatron accelerator have published first results of searches for the Higgs boson, excluding parts of the otherwise allowed mass range.

Observation of a two-neutron halo in ${}^{22}\text{C}$ makes it the heaviest “Borromean” nucleus yet observed.

A very high magnetic field splits the zero-energy Landau level of bilayer graphene revealing eight distinct levels.

New experiments extend chemical dynamics research to temperatures below $1$ microkelvin.

By doping the topological insulator bismuth selenide with copper to form copper layers, a topological superconductor is created.

The combination of trivial and topological band insulators with a superconductor is bringing anyons—particles that behave neither according to purely Bose nor Fermi statistics—into the three-dimensional world.

New excited states have been observed in ${}^{212}\text{Po}$ that are associated with a configuration in which an alpha particle is combined with a doubly-magic ${}^{208}\text{Pb}$ core.

The signal-to-noise ratio for room-temperature readout of individual qubits can be substantially improved by taking an indirect route through intermediate energy levels.

With the right configuration of laser beams, researchers could measure how much of an ultracold atomic gas is actually superfluid.

Supersonic jets of air can be produced when a solid object falls into water.

A new experiment shows that entangled electron pairs can be spatially split into different arms of a carbon nanotube. Is a nanotube quantum teleporter on the horizon?
