Researchers develop a new approach to measuring the viscoelastic properties of multicellular aggregates by using a micropipette aspiration technique.

New calculation of quark matter properties tells us what an exotic quark-neutron star might look like.

New calculations of the effects of asymmetry in numbers of neutrons and protons in nuclei agree well with experiment and provide vital information in understanding nuclear matter at low density.

Measurements with a scanning probe microscope sensitive to micron-scale magnetization variations provide evidence for stripes of enhanced superfluid density at the surface of an iron-pnictide superconductor.

New measurements of the rigidity of solid helium show that the emergence of supersolidity is actually a crossover, rather than a true phase transition.

Making simple modifications to laser-scanning microscopes—like those found in many laboratories—can beat the classical diffraction limit by a factor of $2$.

Magnetic resonance images of tetrahedral dice show a density of random close packing, in agreement with recent calculations.

Vibrations of the atoms in a molecule are used to implement a Fourier transform orders of magnitude faster than possible with devices based on conventional electronics.

Understanding the electronic structure of shape-memory alloys promises magnetic control over their crystal structures and hence mechanical properties.

Quantum interference effects can, in theory, lead to the emergence of new particles carrying exotic quantum numbers at a critical point. But how good is the evidence that this happens?

Quantum jumps such as those observed in photon emission from single molecules show a complex behavior that may indicate a phase transition between different kinds of temporal dynamics.

New experiments create pairs of vortices of opposite circulation by forcing a Bose-Einstein condensate to flow past an obstacle.

Researchers have found a way to naturally double the frequency of laser light with an optical microresonator made from lithium niobate that supports “whispering gallery” modes.

A collaboration of Russian and US physicists has created the superheavy element 117, an experimental achievement that fills in the final gap on the list of observed elements up to element 118.
