Study warns climate leadership falling short in New Zealand
New Zealand leaders favor small, incremental changes in response to escalating climate impacts rather than the bold changes needed to make a real difference, according to research by University of Auckland academic Dr. Sasha Maher and Professor Brad Jackson (University of Waikato).

Universal tradeoff relations between resource cost and irreversibility of channels: General-resource Wigner-Araki-Yanase theorems and beyond
Quantum technologies offer exceptional -- sometimes almost magical -- speed and performance, yet every quantum process costs physical resources. Designing next-generation quantum devices, therefore, depends on solving the following question: which resources, and in what amount, are required to implement a desired quantum process? Casting the problem in the language of quantum resource theories, we prove a universal cost-irreversibility tradeoff: the lower the irreversibility of a quantum proces…

Potatoes are mutant hybrids with... tomatoes.

The modern potato evolved from a wild tomato fling 9 million years ago, scientists say
A chance encounter between a wild tomato and a potato-like plant 9 million years ago is why we have modern-day potatoes, according to new research.

Brilliant week in Bristol.
Especially invigorating to present the invited talk, 'Private Education Capital: Beyond Caste-based Educational Exclusion as "Tradition"' at Centre for International Research in Education. I also gave a Roundtable Presentation, 'Epistemic Humility as Experienced Provocation' for doctoral students.
Grateful to wonderful colleagues who took such care, asked such thoughtful questions, and showed me beautiful Bristol with scrumpt…

For some time, I had the feeling that even the 9000 series may become irrelevant pretty fast. IMO, this move places the 7000 and 9000 series on the very long-term support list. But it's a bloody sacrifice, what they do to the 6000 series owners :/ Strangely, I feel for AMD having to make thеsе kinds of tough decisions. They must've absolutely stretched out their resources right now.

Polynomials and asymptotic constants in a resurgent problem from 't Hooft
In a recent study of the quantum theory of harmonic oscillators, Gerard 't Hooft proposed the following problem: given $G(z)=\sum_{n>0}\sqrt{n}z^n$ for $|z|<1$, find its analytic continuation for $|z|\ge1$, excluding a branch-cut $z\in[1,\,\infty)$. A solution is provided by the bilateral convergent sum $G(z)=\frac12\sqrtπ\sum_{n\in{\mathbb Z}}(2nπ{\rm i}-\log(z))^{-3/2}$. On the negative real axis, $G(-e^u)$ has a sign-constant asymptotic expansion in $1/u^2$, for large p…

StepORLM: A Self-Evolving Framework With Generative Process Supervision For Operations Research Language Models
Large Language Models (LLMs) have shown promising capabilities for solving Operations Research (OR) problems. While reinforcement learning serves as a powerful paradigm for LLM training on OR problems, existing works generally face two key limitations. First, outcome reward suffers from the credit assignment problem, where correct final answers can reinforce flawed reasoning. Second, conventional discriminative process supervision is myopic, failing to evaluate the interdependent steps of OR mo…

Photonic Simulation of Beyond-Quantum Nonlocal Correlations (e.g. Popescu-Rohrlich Box) with Non-Signaling Quantum Resources
Bell nonlocality exemplifies the most profound departure of quantum theory from classical realism. Yet, the extent of nonlocality in quantum theory is intrinsically bounded, falling short of the correlations permitted by the relativistic causality (the no-signaling) principle. A paradigmatic example is the Popescu-Rohrlich correlation: two distant parties sharing arbitrary entanglement cannot achieve this correlation, though it can be simulated with classical communication between them. Here we…
