Synopsis: Reversible Self-Assembly of Macroscopic “Polymers”
Reconfigurable materials step closer to reality with a colloidal system that self-assembles, disassembles, and reassembles into polymer-like chains in response to temperature changes. Read More »
Synopsis: Solar Gamma Rays Behaving Strangely
Nearly 10 years of Fermi telescope images show unexpected changes in the numbers and energies of gamma-ray photons coming from the Sun. Read More »
Focus: Gas Cloud Temperature Constrains Dark Matter
One proposed type of dark matter should heat up cold hydrogen clouds in the Galaxy, so their low temperatures imply limits on this dark matter theory. Read More »
Viewpoint: Non-Hermitian Topological Systems
A theoretical framework tries to sort out where topological phases may arise in non-Hermitian systems—which are systems with gain and loss. Read More »
Synopsis: Anisotropic Spin Currents in Graphene
Two groups have shown they can create long-lived, polarized spin currents in bilayer graphene. Read More »
Synopsis: A Faster Diamond Magnetometer
Diamond-defect magnetometers can now simultaneously determine all spatial components of a magnetic field, leading to a factor of 4 decrease in measurement times. Read More »
Viewpoint: Circuit Simulates One-Dimensional Quantum System
An electrical circuit simulates a quantum phase transition induced by the presence of an impurity in a one-dimensional conductor. Read More »
Synopsis: Knotted Loops Fall Flat
A knotted loop of metal beads—mimicking a knotted molecule—organizes into a flat horizontal ring when drifting down through a viscous fluid. Read More »
Viewpoint: Higgs Decay into Bottom Quarks Seen at Last
Two CERN experiments have observed the most probable decay channel of the Higgs boson—a milestone in the pursuit to confirm whether this remarkable particle behaves as physicists expect. Read More »
