Knot complements decomposing into prisms
We describe four hyperbolic knot complements in $\mathbb{S}^3$, each of which covers a prism orbifold: the quotient of $\mathbb{H}^3$ by the action of a discrete group generated by reflections in the faces of a polyhedron that has the combinatorial type of a triangular prism. The prism orbifolds are rigid-cusped and contain compact, totally geodesic hyperbolic triangle sub-orbifolds; as a result, the knot complements covering them have hidden symmetries and contain closed, embedded, totally geo…

Universal dynamics and microwave control of programmable cavity electro-optic frequency combs
Electro-optic (EO) frequency combs are foundational for metrology and spectroscopy. Specifically, microresonator-based cavity EO combs are distinguished by efficient sideband generation, precisely controlled by microwave signals, enabling high-performance integrated frequency references and pulse sources. However, the apparent simplicity of these devices, often described by the EO modulation-induced coupling of nearest-neighbor cavity modes, has limited investigations of their fundamental physi…

Transient MeV radiation from a relativistic tidal disruption candidate
On July 2, 2025, the Gamma-ray Burst Monitor (GBM) onboard the Fermi Gamma-ray space telescope detected three short-duration MeV transients with overlapping sky locations. These events, named as GRB 250702D, B, and E (collectively referred to as DBE), triggered the detector with delays of approximately 1-2 hours between each burst. Follow-up observations of this unusually long MeV transient (lasting >3 hours) by the Neil Gehrels Swift Observatory and the Nuclear Spectroscopic Telescope Array ov…

Conservative leader Kemi Badenoch said he was "flirting with Neil Kinnock's demand for a wealth tax" after the former Labour leader called for one on Sky News.
Sir Keir Starmer dodged the question by saying his government has stabilised the economy, but was asked again by Green Party co-leader Adrian Ramsay if he would stand by his promise that "those with the broadest shoulders should carry the largest burden".
The Prime Minister simply said: "We can…
