The formation and evolution of dust in the colliding-wind binary Apep revealed by JWST
Carbon-rich Wolf-Rayet (WR) stars are significant contributors of carbonaceous dust to the galactic environment, however the mechanisms and conditions for formation and subsequent evolution of dust around these stars remain open questions. Here we present JWST observations of the WR+WR colliding-wind binary Apep which reveal an intricate series of nested concentric dust shells that are abundant in detailed substructure. The striking regularity in these substructures between successive shells su…

Rather than assuming the war can be ended through a comprehensive battlefield victory or a negotiated compromise,
Ukraine and its allies must plan to build a viable, sovereign, and secure state under constant military pressure.
This reality demands a redefinition of what a successful outcome looks like.
In this context, the objective should not be to defeat Russia outright or expect its regime to end the war because of economic or diplomatic pressure
-- but to syste…

Ukraine’s New Theory of Victory Should be Strategic Neutralization
By ensuring that Russia’s war is operationally pointless, Ukraine can survive, adapt, and achieve success, no matter how prolonged the war.

Oh no, hope he's not ill! 😕
After successfully convincing warmongering dictator #Zelenskyy to finally agree to the #russia‎n republic's long-proposed peace negotiations and generously inviting him to Tsargrad, our beloved president, the humble vladimir

OH – food for thought: “They've found ways to be successful critics – emphasis on successful. They get invited to conferences, win awards, maintain influence … that success might come from never truly threatening the system.
Maybe aggressive rhetoric and a bridge-burning approach isn’t a bug but a feature. When the house is on fire, you don’t negotiate with the arsonists about fire safety regulations. You sound the alarm, loudly and repeatedly.
In a truly existential fight, w…

Adsorbate phase transitions on nanoclusters from nested sampling
Nested sampling was employed to investigate adsorption equilibria on the truncated-octahedral Lennard-Jones nanocluster LJ$_{38}$ while systematically varying adsorbate-surface well depth and Lennard-Jones size parameters. Evaluation of the canonical partition function over a wide temperature range identifies two successive phase transitions: (i) condensation of the gas phase onto the cluster surface at higher temperatures, and (ii) lateral rearrangement of the adsorbed layer at lower temperatu…
