Massive quiescent galaxies are common from redshift 2 to 5
This research indicates that massive quiescent galaxies are surprisingly common at 2 < z < 5, with number densities of at least about 10^-5 Mpc^-3 by 4 < z < 5.

Mobile-assisted experiments increased interest but not performance
This research indicates that mobile-assisted, hands-on projectile motion experiments were associated with very high student interest but low academic performance and a very weak link between the two.

Proton resonance radii show an early-time plateau and threshold increase
This research indicates that the radius of a proton resonance can match the experimentally accessible real-energy radius during an early-time plateau, and that the charge radius shows a local increase across the threshold.

Self-gravitating bosonic configurations show critical stability limits
This research indicates that self-gravitating bosonic configurations in the nonrelativistic regime have a critical central density and a maximum particle number beyond which no stationary solutions are found.

Hydrodynamic form of non-relativistic quantum mechanics extended
This research indicates that a hydrodynamic interpretation of non-relativistic quantum mechanics can be extended by quantising a single, spinless particle constrained to a small-slope surface wave.

TTCF computed transport coefficients efficiently in two model systems
This research indicates that the Transient Time Correlation Function method can compute nonequilibrium transport coefficients from short-time transients, with reduced computational cost in the Lorentz gas and efficient scaling in a one-dimensional oscillator chain.

Nonlocal media support fast and slow dark-antidark soliton pairs
This research indicates that one-dimensional two-component defocusing nonlinear Schrödinger systems with nonlocal interactions can support two families of vector soliton pairs, including a mixed dark-antidark class.
