Bose–Einstein condensate emits harmonics in a pure quantum state
This research indicates that high harmonic generation from a Bose–Einstein condensate can produce harmonic radiation in a pure quantum state below the critical temperature, while the generated harmonics of a driven Bose gas are a classical mixture.

GW170817 analysis gives tighter constraints on viewing angle and H0
This research indicates that reanalyzing GW170817 with a Bayesian visibility-plane model and multiple very long baseline interferometry data sets yields tighter constraints on the jet viewing geometry, luminosity distance, and Hubble’s constant.

Two intersecting radio shells found around a compact galaxy group
This research indicates that at least some odd radio circles are shock-energised relics in the outskirts of galaxy groups, formed during the merger evolution of the brightest group galaxy.

Shear changes early gel behavior but not final strength
This research indicates that shearing before the critical gel point changes the material’s early viscoelastic behavior, but not its final gel time or 7-day compressive strength.

Kilonova-like bursts may also fit a collapsar model
This research indicates that kilonova-like emission after long-duration gamma-ray bursts can also be consistent with a collapsar scenario rather than only a neutron star merger.

Review compares stimulation methods for muscle-driven biohybrid robots
This research indicates that muscle-driven biohybrid robots have several stimulation strategies, but greater actuation, precise control, longer-term viability, and programmability remain goals.

Mean-field methods qualitatively map heavy-quark QCD phase behavior
This research indicates that analytical mean-field methods can qualitatively describe the phase diagram of lattice QCD with heavy quarks, including a first-order nuclear liquid-gas transition and a critical end point at very low temperatures.

Scalar leptoquarks can help a vector-like lepton dark matter model fit constraints
This research indicates that adding scalar leptoquarks can change vector-like lepton dark matter so it can better evade direct detection limits and match the observed relic abundance.
