Disentangling conviction and conformity: a Bayesian ideal point model of voting behaviour in online debates
arXiv:2606.03786v1 Announce Type: new Abstract: Online debate platforms offer a unique window into the mechanisms driving opinion formation: they capture both explicit political preferences and the peer environment in which those preferences are expressed. In this work, I develop a Bayesian logistic regression model, inspired by ideal point models from political science, to disentangle two competing mechanisms of voting behaviour in online debates: conviction, driven by prior ideological...
Study highlights key welfare needs for seal pups in rehabilitation
Study highlights key welfare needs for seal pups in rehabilitation Lisa Lock Scientific Editor Andrew Zinin Lead Editor A new study examining harbor and gray seal pups undergoing rehabilitation in the U.S. has identified important steps that could improve animal welfare during their recovery. Researchers from the University of Chester and Manchester Metropolitan University monitored 25 seal pups admitted to Tynemouth Seal Hospital after becoming stranded due to reasons such as...
Scenario Generation for Risk-Aware Reinforcement Learning with Probably Approximately Safe Guarantees
arXiv:2606.04812v1 Announce Type: new Abstract: Guaranteeing safety is critical to the deployment of reinforcement learning (RL) agents in the real-world, especially as policies learned using deep RL may demonstrate susceptibility to transition perturbations that result in unknown or unsafe behaviour. A method of policy verification is to construct probabilistic barrier-certificates by sampling policy trajectories with respect to safety constraints, thereby demarcating known safe behaviour...
Effect of a magnetostatic field on laminar premixed hydrogen-air flames
arXiv:2606.10188v1 Announce Type: new Abstract: Magnetic fields have shown potential to affect flame characteristics; however, the mechanisms of interaction are not fully understood. This paper investigates the effect of magnetic fields on premixed hydrogen-air flames that are prone to intrinsic instabilities, with a focus on the role of magnetic forces on the flame behaviour.

(2R,6R)-Hydroxynorketamine elicits rapid antidepressant effects by promoting astrocytic μ-δ opioid receptor heterodimerization
Ketamine produces rapid antidepressant effects but is constrained by psychotomimetic properties and abuse potential. The ketamine metabolite (2R,6R)-hydroxynorketamine (HNK) shows antidepressant-like efficacy without N-methyl-D-aspartate receptor (NMDAR) blockade, yet its upstream targets remain unclear. Here we show that HNK potentiates hippocampal excitatory transmission and reverses stress-induced behavioural deficits through opioid receptor signaling.
Robots Need More than VLA and World Models
arXiv:2606.06556v1 Announce Type: new Abstract: Generalist robot intelligence is often framed as a policy-scaling problem: collect more robot demonstrations, train larger Vision-Language-Action (VLA) models, and expect broader generalisation. In this position paper, we argue that this framing is incomplete. The central bottleneck is not only policy learning, but the absence of mechanisms that convert the world's abundant unstructured behavioural data into grounded robot supervision.
Toward Scalable Co-located Practical Learning: Assisting with Computer Vision and Multimodal Analytics
Announce Type: replace Abstract: Co-located practical learning leaves evidence in visible actions around patients, task resources and room zones, but these traces are often recovered through live observation or retrospective video review. Fixed wide-angle video could reduce sensing burden, yet a debriefing pipeline must do more than detect behaviours: it must maintain detection after small camera-position shifts, relate the detector-derived behaviour trace to instructor-labelled outcomes and...
The Piggyback Hypothesis of Generalization: Explaining and Mitigating Emergent Misalignment
arXiv:2606.06667v1 Announce Type: new Abstract: The mechanisms behind LLMs' broad over-generalization beyond training examples remain unclear. Emergent misalignment (EM) offers a striking case study: finetuning on narrow tasks induces broad misalignment to semantically-unrelated test domains. In this work, we propose the Piggyback Hypothesis: the chat-template tokens can piggyback the finetuned behaviour onto out-of-domain queries.
Good recycling starts at home — and benefits the world
Nature, Published online: 09 June 2026; doi:10.1038/d41586-026-01823-yNew research supports the value of household-level waste separation. But policies must also carefully consider consumer behaviours to maximize the quality of material collected.
