Abstract Hulu's Prey (2022), the fifth installment of the Predator franchise, is set in 1719 and features a Comanche female protagonist. The setting is unlike the 1987 Predator and its sequels, with their hardbody machismo and conservative politics. We argue that Prey is a small but significant step in Hollywood, but its inclusivity comes at a price ...

Strong GeV Emission Accompanying TeV Blazar H1426+428
For High frequency BL Lac objects (HBLs) like H1426+428, a significant fraction of their TeV gamma-rays emitted are likely to be absorbed in interactions with the diffuse IR background, yielding $e^\pm$ pairs.

Evidence for a new light spin-zero boson from cosmological gamma-ray propagation?
Recent findings by Imaging Atmospheric Cherenkov Telescopes indicate a large transparency of the Universe to gamma rays, which can be hardly explained within the current models of extragalactic background light.

The End of the Rainbow: What Can We Say About the Extragalactic Sub-Megahertz Radio Sky? [PDF]
The Galactic disc is opaque to radio waves from extragalactic sources with frequencies nu less than ~3 MHz. However, radio waves with kHz, Hz, and even lower frequencies may propagate through the intergalactic medium (IGM).

The biophysical and compositional properties of human basement membranes
Basement membranes are exceptionally adaptable materials with both extremely stiff and highly elastic properties. This article highlights these features on a selection of human membranes and links them to compositional, biomechanical, and structural profiles down to a molecular level. The role of water in modulating these attributes is also scrutinized

Blazars are expected to produce both gamma rays and cosmic rays. Therefore, observed high-energy gamma rays from distant blazars may contain a significant contribution from secondary gamma rays produced along the line of sight by the interactions of ...

Magnetic Field Seeding by Galactic Winds [PDF]
The origin of intergalactic magnetic fields is still a mystery and several scenarios have been proposed so far: among them, primordial phase transitions, structure formation shocks and galactic outflows.

The Adventures of the Rocketeer: Accelerated Motion Under the Influence of Expanding Space
It is well known that interstellar travel is bounded by the finite speed of light, but on very large scales any rocketeer would also need to consider the influence of cosmological expansion on their journey.

TeV gamma rays from blazars beyond z=1?
At TeV energies, the gamma-ray horizon of the universe is limited to redshifts z1, if the observed gamma rays are secondary photons produced in interactions of high-energy protons originating from the blazar jet and propagating over cosmological ...

Super-GZK Photons from Photon-Axion Mixing
We show that photons with energies above the GZK cutoff can reach us from very distant sources if they mix with light axions in extragalactic magnetic fields.
