Be less polite: How to cut your AI impact as UN report reveals data centre energy use rivals nations
"That extra ‘please’ you put there can make a huge difference,” says one of the report's authors. The environmental footprint of data centres already rivals some of the world's largest countries, according to a United Nations University report released on 3 June. Their water use, energy use and pollution is predicted to double in just four years as use of artificial intelligence grows.
Certificates without Electrons? Theory and Evidence on Impacts from AI-Driven Power Demand
arXiv:2606.00811v1 Announce Type: cross Abstract: Data centers now account for 4.4% of United States electricity demand, yet the grid-level effectiveness of the renewable energy certificates (RECs) and power purchase agreements (PPAs) hyperscalers use to claim carbon neutrality remains unclear. We develop a game-theoretic model in which a data center operator chooses among RECs, PPAs, and behind-the-meter colocation while generators make entry decisions under endogenous financing costs. The...
BLISS: A Lightweight Bilevel Influence Scoring Method for Data Selection in Language Model Pretraining
Announce Type: replace Abstract: Effective data selection is essential for pretraining large language models (LLMs), enhancing efficiency and improving generalization to downstream tasks. However, existing approaches often require leveraging external pretrained models, making it difficult to disentangle the effects of data selection from those of the external pretrained models. In addition, they often overlook the long-term impact of selected data if the model is trained to convergence,...
Charter breach warning: What customers should know
A phone call may have opened the door to a major telecom security scare involving Charter Communications, the company behind Spectrum. Charter is one of the largest broadband and cable providers in the United States, serving more than 32 million customers across more than 40 states with internet, cable TV, mobile and phone service. The company has confirmed a cybersecurity incident after the ransomware group ShinyHunters listed it on a leak site.

Data Compression with Stochastic Codes
arXiv:2602.07635v2 Announce Type: replace Abstract: Machine learning has had a major impact on data compression over the last decade and opened up many new theoretical and applied fields of inquiry. This paper describes one such direction -- relative entropy coding -- which focuses on constructing stochastic codes, mainly as an alternative to quantisation and entropy coding in lossy source coding. Our primary aim is to provide a broad overview of the topic, with an emphasis on the...
Meta confirms 1000s of Instagram accounts were hacked by abusing its AI chatbot
Meta confirms thousands of Instagram accounts were hacked by abusing its AI chatbot Meta is notifying thousands of people whose Instagram accounts were hijacked during the months-long abuse of the company's AI chatbot, which hackers repeatedly tricked into taking control of a person's account. In a new data breach notification letter, seen by this week in security, Meta has revealed for the first time how many people had their accounts hijacked as part of the long-running hacking campaign,...
Carnival breach may put your travel data at risk
Carnival Corporation has confirmed a data breach affecting nearly 6 million people, and the fallout could reach travelers who may not think of themselves as Carnival customers. The company says the incident involved a social engineering attack on a single user account. In other words, someone fooled an employee and gained access to part of Carnival's IT system.

Optimal Regularization for Performative Learning
arXiv:2510.12249v2 Announce Type: replace Abstract: In performative learning, the data distribution reacts to the deployed model - for example, because strategic users adapt their features to game it - which creates a more complex dynamic than in classical supervised learning. One should thus not only optimize the model for the current data but also take into account that the model might steer the distribution in a new direction, without knowing the exact nature of the potential shift. We...
