Invasion intensifies on Karipuna Indigenous land in the Brazilian Amazon
Illegal invasions in the Karipuna Indigenous Territory in the northwest of the Brazilian Amazon have started to advance again, Karipuna leaders told Mongabay following an alert by global nonprofit Survival International. “This year has been very difficult because there are a lot of people on our territory,” André Karipuna, the chief of the Karipuna people, […]

IMEX-RB: a self-adaptive IMEX time integration scheme exploiting the RB method
In this work, we introduce a self-adaptive implicit-explicit (IMEX) time integration scheme, named IMEX-RB, for the numerical integration of systems of ordinary differential equations (ODEs), arising from spatial discretizations of partial differential equations (PDEs) by finite difference methods. Leveraging the Reduced Basis (RB) method, at each timestep we project the high-fidelity problem onto a suitable low-dimensional subspace and integrate its dynamics implicitly. Following the IMEX para…

External charged debris in a flowing plasma : charge fluctuation induced complexity
In this work, we investigate the response of a flowing e-i plasma to embedded external charged debris, focusing on the periodic debris charge fluctuations that can trigger complex phenomena such as chaos and nonlinear Landau damping. We employ both kinetic and fluid simulations to analyse the plasma response to the time-dependent debris charge. Our findings indicate that the nature of the nonlinear response can be considerably different for fluctuating positively charged external debris from ne…

Voice-based AI Agents: Filling the Economic Gaps in Digital Health Delivery
The integration of voice-based AI agents in healthcare presents a transformative opportunity to bridge economic and accessibility gaps in digital health delivery. This paper explores the role of large language model (LLM)-powered voice assistants in enhancing preventive care and continuous patient monitoring, particularly in underserved populations. Drawing insights from the development and pilot study of Agent PULSE (Patient Understanding and Liaison Support Engine) -- a collaborative initiati…

We’re on a terrible path that we aren’t even aware exists: collapsing the marine food chain.
The End Permian event did that. It was ugly. Lots of fungal spores in the fossil record, not a lot of bones. Barely anything survived.
We’re having issues with phytoplankton in the #GreatLakes too. Invasive mussels have done huge damage to how the food chain (Esp. in

Nonexistence of Consecutive Powerful Triplets Around Cubes with Prime-Square Factors
The Erdős-Mollin-Walsh conjecture, asserting the nonexistence of three consecutive powerful integers, remains a celebrated open problem in number theory. A natural line of inquiry, following recent work by Chan (2025), is to investigate potential counterexamples centered around perfect cubes, which are themselves powerful. This paper establishes a new non-existence result for a family of such integer triplets with distinct structural constraints, combining techniques from modular arithmetic, $…

I really don't want to diss all these lovely people who've practised so hard, but I can't help feeling that the theme of tonight's #BBC4 #prom is "music a detective show might use to indicate that an important witness is having a psychotic episode".
