Supreme Court clears way for Trump to gut education department – live updates
The supreme court has cleared the way for Donald Trump’s administration to resume dismantling the Department of Education -- part of his effort to shrink the federal government’s role in education in favor of more state control.
In the latest high court win for Trump, the justices lifted a federal judge’s order that had reinstated nearly 1,400 workers affected by mass layoffs at the department and block…

Whispers from the Early Universe: The Ringdown of Primordial Black Holes
We investigate the stochastic gravitational wave background (SGWB) generated by the ringdown phase of primordial black holes (PBHs) formed in the early universe. As the ringdown signal is independent of the PBH formation mechanism, the resulting SGWB offers a model-independent probe of PBHs. We numerically compute the ringdown waveform and derive the corresponding SGWB. We show that such a signal could be detected by future pulsar timing arrays (PTAs) for PBHs heavier than the solar mass. Addit…

PhyBlock: A Progressive Benchmark for Physical Understanding and Planning via 3D Block Assembly
While vision-language models (VLMs) have demonstrated promising capabilities in reasoning and planning for embodied agents, their ability to comprehend physical phenomena, particularly within structured 3D environments, remains severely limited. To close this gap, we introduce PhyBlock, a progressive benchmark designed to assess VLMs on physical understanding and planning through robotic 3D block assembly tasks. PhyBlock integrates a novel four-level cognitive hierarchy assembly task alongside …

Primordial Black Hole Ringdown: the Irreducible Stochastic Gravitational Wave Background
Independently from the formation mechanism of primordial black holes in the early universe, their generation is accompanied by a ringdown phase during which they relax to a stationary configuration and gravitational waves under the form of quasinormal modes are emitted. Such gravitational waves generate an irreducible and unavoidable stochastic background which is testable by current and future experiments. In particular, the presence of a primordial black hole ringdown allows to significantly …

Nonlinearities in Kerr Black Hole Ringdown from the Penrose Limit
We provide a fully analytical approach to calculate the nonlinearities of the gravitational waves in the ringdown of a Kerr black hole in the eikonal limit. The corresponding quasi-normal modes are associated to the orbits of a closed circular null geodesic and the problem can be analyzed by taking the Penrose limit around it. We calculate analytically the amplitude and the phase of the quadratic quasi-normal modes as well as its dependence on the black hole spin.
