Echoes of bimodal axial gravitational perturbations in a uniform-density star in Einstein-Æther gravity
This paper studies axial gravitational perturbations of a uniform-density star in scalar-Einstein-Æther theory. By applying the Israel junction conditions explicitly in the presence of a scalar field minimally coupled to the gravitational sector, it is shown that a nontrivial scalar profile cannot be sustained, as it induces a divergence at the stellar center. Since analytical solutions are unattainable, the background metric is determined through numerical integration for a few representative…

Q1’s –0.5% growth is already a bad look. But Apollo’s Torsten SlŸk points out that data-center construction alone added about a full percentage point. Remove it, and you’re staring at –1.5%.
Q2 looks so much healthier at 3.0%, or you would think so. Pantheon Macroeconomics sums up the first half of 2025 with some more sobriety: AI alone contributed about half a percentage point of GDP. Without it, the U.S. would be bumbling along at 1% growth. Still better than minus, but thin grass all the same.
One more stat for the better view: since 2019, investment in AI-sensitive sectors is up 53%, while everywhere else is basically flat – 0.3%.

Bridging Boundaries: How to Foster Effective Research Collaborations Across Affiliations in the Field of Trust and Safety
As the field of Trust and Safety in digital spaces continues to grow, it has become increasingly necessary - but also increasingly complex - to collaborate on research across the academic, industry, governmental and non-governmental sectors. This paper examines how cross-affiliation research partnerships can be structured to overcome misaligned incentives, timelines and constraints while delivering on the unique strengths of each stakeholder. Drawing on our own experience of cross-sector collab…

Higgs branch of 5d $\mathcal{N}=1$ symplectic gauge theories and dressed instanton operators

Higgs branch of 5d $\mathcal{N}=1$ symplectic gauge theories and dressed instanton operators
We expand in instanton charge sectors the representation content of the infinite coupling chiral ring of the Higgs branch of 5d $\mathcal{N}=1$ $Sp(k)$ theories with $N_f$ flavours. The entire chiral ring can be expressed as the product of bare instantons, one for each topological sector, times a common dressing factor depending on the mesons and the instanton-anti instanton bound state. The dressing factor, which is independent of the instanton number, encodes the chiral ring of the theory at …

Stopping Dark Mesons in Their Tracks with Long-Lived Particle and Resonant Signatures
Dark sectors with confining gauge interactions can provide both simple dark matter candidates and striking signals at colliders. We recast Large Hadron Collider searches for two different signatures of dark mesons that arise from a strongly-coupled theory with vector-like dark quarks that are in some non-trivial representation of Standard Model SU(2)$_L$. For any such electroweak representation, there is a 3-plet of dark mesons whose charged components are long-lived, and we reinterpret searche…

The JWST Rocky Worlds DDT Program reveals GJ 3929b to likely be a bare rock
We report first results from the JWST Rocky Worlds Director's Discretionary Time program. Two secondary eclipses of the terrestrial exoplanet GJ 3929b were recently observed using MIRI photometric imaging at 15 um. We present a reduction of these data using the updated SPARTA pipeline. We also refine the planet mass, radius, and predicted time of secondary eclipse using a new sector of TESS data and new, high-precision radial velocities from the MAROON-X spectrograph. For the two JWST observati…

Exotic multistrange-anticharm baryon systems
We study exotic baryon systems composed of anticharmed mesons and strange baryons using the extended local hidden gauge approach. By solving the coupled-channel Bethe-Salpeter equation with interaction kernels from vector meson exchange, we explore the formation of hadronic molecular states in sectors with strangeness $S = -1$, $-2$, $-3$ and $-4$. A bound state with a mass of 2888 MeV is found in the $S = -1$ sector with the channels $\bar{D}_s N, ~\bar{D} Λ, ~\bar{D} Σ$. In the $S = -2$ sec…

Molecular states with bottom mesons and multistrange baryons systems
We investigate molecular states formed by bottom mesons and multistrange baryons from both octet and decuplet flavor representations, using the local hidden gauge approach combined with coupled-channel Bethe-Salpeter equations. Focusing on strangeness sectors \(S = -1\) to \(-4\), we predict several bound states in the \(S=-1, I=1/2,~3/2\) and \(S=-2, I=0\) sectors. No bound states are found in other isospin channels, where the interaction is repulsive, nor in higher strangeness sectors. The bi…
