Primordial Black Hole Triggered Type Ia Supernovae I: Impact on Explosion Dynamics and Light Curves
Primordial black holes (PBHs) in the asteroid-mass window are compelling dark matter candidates, made plausible by the existence of black holes and by the variety of mechanisms of their production in the early universe. If a PBH falls into a white dwarf (WD), the strong tidal forces can generate enough heat to trigger a thermonuclear runaway explosion, depending on the WD mass and the PBH orbital parameters. In this work, we investigate the WD explosion triggered by the passage of PBH. We perfo…

Common ownership? Never, so long as society clings to economic monopolies and the machinery of state, true freedom for all remains impossible!
As Rocker argued, only the abolition of all monopolies and the creation of a federation of free communities, where the land and means of production belong to everyone, not privileged minorities, can end exploitation and allow genuine liberty to flourish.
Until then, "common ownership" is just a slogan, not a living reality.

Ukraine and the United States to build joint facility for ammunition production: https://benborges.xyz/2025/07/16/ukraine-and-the-united-states.html

As Russia wages its full-scale war against Ukraine, one of its most important missile plants is quietly expanding -- bypassing international sanctions.
The Votkinsk Plant, also known as the Votkinskiy Plant,
— a strategic, state-owned facility serving Russia’s nuclear forces
— has hired thousands of new workers,
added new buildings,
and brought in advanced machinery to significantly increase its missile production.
Ukrainians have felt it firsthand.

Investigation: Russia expands strategic plant producing ICBMs — with China’s help
Key findings: * Despite international sanctions, Russia's strategic missile plant was able to import complex machinery to dramatically increase missile production. * The Kyiv Independent has identified the equipment supplied to the plant, as well as the supply chains, mostly from China. * We located the plant's new premises, built to house the new machinery. * We obtained a document confirming that the plant received an order to produce intercontinental missiles capable of reaching the U.S.

Active viscoelastic condensates provide controllable mechanical anchor points
Many biological materials must couple mechanical strength with the ability to rapidly self-assemble at a specific location. In particular, biomolecular condensates readily self-assemble via phase separation, but may also need to resist external forces to fulfil their function. Spatial localisation of condensate formation can be controlled by active cores that preferentially drive the production of condensate material at a particular point, while resistance to external forces can be facilitated …
