Environment Animals Wildlife Endangered Species Death Valley National Park needs help ID'ing joyriding vandals A truck illegally tore through the California park, leaving five miles of tracks and damaging'sensitive desert plants.' Breakthroughs, discoveries, and DIY tips sent six days a week. Death Valley National Park officials are searching for a couple of brazen blockheads, and they could use your help finding them. Specifically, they're looking for at least two people last spotted in Eureka Dunes . The region located about 120 miles east of Fresno, California features what are likely the tallest sand dunes in North America.

Non-invasive Brain-Computer Interfaces (BCIs) based on Code-Modulated Visual Evoked Potentials (C-VEPs) require highly robust decoding methods to address temporal variability and session-dependent noise in EEG signals. This study proposes and evaluates several deep learning architectures, including convolutional neural networks (CNNs) for 63-bit m-sequence reconstruction and classification, and Siamese networks for similarity-based decoding, alongside canonical correlation analysis (CCA) baselines. EEG data were recorded from 13 healthy adults under single-target flicker stimulation. The proposed deep models significantly outperformed traditional approaches, with distance-based decoding using Earth Mover's Distance (EMD) and constrained EMD showing greater robustness to latency variations than Euclidean and Mahalanobis metrics. Temporal data augmentation with small shifts further improved generalization across sessions. Among all models, the multi-class Siamese network achieved the best overall performance with an average accuracy of 96.89%, demonstrating the potential of data-driven deep architectures for reliable, single-trial C-VEP decoding in adaptive non-invasive BCI systems.

LLM agents have begun to appear as personal assistants, customer service bots, and clinical aides. While these applications deliver substantial operational benefits, they also require continuous access to sensitive data, which increases the likelihood of unauthorized disclosures. Moreover, these disclosures go beyond mere explicit disclosure, leaving open avenues for gradual manipulation or sidechannel information leakage. This study proposes an auditing framework for conversational privacy that quantifies an agent's susceptibility to these risks. The proposed Conversational Manipulation for Privacy Leakage (CMPL) framework is designed to stress-test agents that enforce strict privacy directives against an iterative probing strategy. Rather than focusing solely on a single disclosure event or purely explicit leakage, CMPL simulates realistic multi-turn interactions to systematically uncover latent vulnerabilities. Our evaluation on diverse domains, data modalities, and safety configurations demonstrates the auditing framework's ability to reveal privacy risks that are not deterred by existing single-turn defenses, along with an in-depth longitudinal study of the temporal dynamics of leakage, strategies adopted by adaptive adversaries, and the evolution of adversarial beliefs about sensitive targets. In addition to introducing CMPL as a diagnostic tool, the paper delivers (1) an auditing procedure grounded in quantifiable risk metrics and (2) an open benchmark for evaluation of conversational privacy across agent implementations.

Hollywood icon Robert Redford has died at the age of 89, his publicist has said. The actor was known for his roles in blockbuster movies such as Butch Cassidy and the Sundance Kid, and went on to win an Oscar for Ordinary People when he turned his hand to directing.

BBC Verify has been to the house in Washington, Utah which has been linked to Tyler Robinson - the suspect in the killing of Charlie Kirk. Sitting in the driveway was a grey car, similar to the model detectives said the suspect had driven to Utah Valley University where Kirk was fatally shot. BBC Verify's Nick Beake has been searching for answers at the location and on social media. Angola: The notorious prison being used in Trump's immigration crackdown The new detention facility inside the prison is designed to hold more than 400 undocumented immigrants convicted of serious crimes. Jackson Denio, a 13-year-old from New Hampshire, might have set the world record for the largest catch of a halibut fish.

Utah Governor Spencer Cox announced Thursday that a suspect in the murder of Charlie Kirk was in police custody. Cox said investigators reviewed video footage and identified Tyler Robinson, 22, arriving in a Dodge Challenger vehicle at approximately 08:29 local time on 10 September. When encountered in person by investigators on 12 September, he was observed in clothing consistent to that in previously released footage, including a plain maroon t-shirt, light-coloured shorts, a black hat with a white logo and light-coloured shoes. Can Trump send National Guard troops to Chicago? Trump has said we're going in, when asked about sending National Guard troops to Chicago, but does he have the power to do this?

The FBI has released new footage showing the suspect in the killing of US activist Charlie Kirk running across a roof - from where the fatal shot was fired - before dropping to the ground and crossing a road. As the authorities continue their search, BBC Verify's Nick Beake has been looking at the footage and what we know about his escape. Watch: Key moments from RFK Jr's heated Senate hearing The US health secretary faced questions on Covid deaths and vaccines a week after firing the head of the Centers for Disease Control and Prevention.
