From plasma to pattern: observation and characterization of periodic structure formation in dielectric breakdown channels of electron-irradiated insulators
Dielectric breakdown of insulators is one of the most common failure modes of electronics in the high-radiation environment of space, but its mechanics remain poorly understood. When electron-irradiated polymethyl methacrylate (PMMA) undergoes breakdown, the resulting channels exhibit striking periodic structures with characteristic wavelengths ~80 μm in the recently identified ivy-mode channels. These previously unobserved modulations offer unique insights into the physics of ultra-fast diele…

Meanwhile Norway had to recover from an attack that opened up a dam that should have remained closed.
It is almost redundant to note that these attacks are coming from Russia. https://infosec.exchange/@mayahustle/115031316869416935

Holey sheets: Double-Threshold Rupture of Draining Liquid Films
Classical rupture is attributed to molecular (van der Waals) forces acting at nanometric thicknesses. Nonetheless, micron-thick liquid sheets routinely perforate far above the scale where these molecular forces act, yet the mechanism that selects opening versus healing has remained unclear. Using direct numerical simulations of a draining sheet with an entrained air bubble (cavity), we show that irreversible rupture occurs only when a deterministic double-threshold is crossed: (i) the outward d…

Most of the garden hasn't gone to plan this year. But the golden raspberries are coming in nicely. Picking them reminds me of advice a friend's grandfather gave me - you'll know it's ripe when the raspberry comes off easily. He always chastised us if we came back with juice-covered hands. #gardenthoughts

The quantum communication power of indefinite causal order
Quantum theory is in principle compatible with scenarios where physical processes take place in an indefinite causal order, a possibility that was shown to yield advantages in several information processing tasks. However, advantages in communication, the most basic form of information processing, have so far remained controversial and hard to prove. Here we develop a framework that can be used to rigorously assess the role of causal order in a scenario where communication links are built by as…

Conference vignette 👀: #OpenScience is about much more than #OpenData. Presenting unpublished work is also Openness, as social science alumna Dr. Ros Attenborough reminded us. And if you can share that way, then...
In the Presidential symposium, another lab alumnus introduced a mouse protein that massively affected the clock ⏰ . His group found it through an ambitious phosphoproteomic 🧪 candidate selection approach on a cell line 🧫 , looking beyond the canonical idea of the clockwork (TTFL in the jargon). Canonical here means canonised by a Nobel prize.
A good friend from Japan explained in the Q&A that his group had just found the SAME gene in a genetic screen of mice 🐁with altered sleep patterns 🐁💤🛌. We know the clock controls sleep. So, independent evidence across continents.👍
Over dinner they started to coordinate how they would each publish their work. #Science working.

Magnetic Atmospheres and Circumstellar Interaction in J1901+1458: Revisiting the Most Compact White Dwarf Merger Remnant in the light of new UV and X-ray data
Double degenerate white dwarf (WD) mergers can exhibit extreme magnetic fields exceeding $10^{8}$ G and rapid rotation, but their spectral-energy distributions and high-energy emission mechanisms remain poorly characterised. ZTF J1901+1458 stands out as the most compact and strongly magnetised object discovered in this class to date. Recent Chandra observations have revealed that the white dwarf is also a source of soft X-ray emission, inconsistent with a photospheric origin. We analyse new pha…

`My Dataset of Love': A Preliminary Mixed-Method Exploration of Human-AI Romantic Relationships
Human-AI romantic relationships have gained wide popularity among social media users in China. The technological impact on romantic relationships and its potential applications have long drawn research attention to topics such as relationship preservation and negativity mitigation. Media and communication studies also explore the practices in romantic para-social relationships. Nonetheless, this emerging human-AI romantic relationship, whether the relations fall into the category of para-social…

Counter-propagating Entangled Photon Pairs from a Monolayer
Non-phase-matched spontaneous parametric down-conversion (SPDC) in atomically thin materials provides new degrees of freedom and enhanced quantum information capacity compared to conventional phase-matched sources. These systems emerged as promising platforms for quantum computing, communication, and imaging, with the potential to support higher-order nonlinear processes. However, direct observation of photon-pair emission from a monolayer has remained experimentally challenging. In this work, …
