A mysterious black cube has joined the chilling list of objects spotted hovering over the US during last year's drone invasion. Newly released government reports have revealed five incidents near Wright-Patterson Air Force Base in Ohio that have never been disclosed since the swarms of UFOs were seen along the East Coast in late 2024. Along with several sightings of unidentified drones around the secretive Air Force base in December 2024, federal officials now say a'black cube'-shaped craft was spotted by a nearby airplane less than 80 miles from Wright-Patterson. Witnesses of the strange object sent their claims to the Federal Aviation Administration (FAA) on December 19, describing how the cube was flying within 500 feet of the plane, which was soaring 16,000 feet above the ground. This would make it incredibly unlikely to be a commercial drone, since those types of devices fly only a few hundred feet above the ground.

Radio remains a pervasive medium for mass information dissemination, with AM/FM stations reaching more Americans than either smartphone-based social networking or live television. Increasingly, radio broadcasts are also streamed online and accessed over the Internet. We present WavePulse, a framework that records, documents, and analyzes radio content in real-time. While our framework is generally applicable, we showcase the efficacy of WavePulse in a collaborative project with a team of political scientists focusing on the 2024 Presidential Elections. We use WavePulse to monitor livestreams of 396 news radio stations over a period of three months, processing close to 500,000 hours of audio streams. These streams were converted into time-stamped, diarized transcripts and analyzed to track answer key political science questions at both the national and state levels. Our analysis revealed how local issues interacted with national trends, providing insights into information flow. Our results demonstrate WavePulse's efficacy in capturing and analyzing content from radio livestreams sourced from the Web. Code and dataset can be accessed at \url{https://wave-pulse.io}.

Creating human-like large language model (LLM) agents is crucial for faithful social simulation. Having LLMs role-play based on demographic information sometimes improves human likeness but often does not. This study assessed whether LLM alignment with human behavior can be improved by integrating information from empirically-derived human belief networks. Using data from a human survey, we estimated a belief network encompassing 18 topics loading on two non-overlapping latent factors. We then seeded LLM-based agents with an opinion on one topic, and assessed the alignment of its expressed opinions on remaining test topics with corresponding human data. Role-playing based on demographic information alone did not align LLM and human opinions, but seeding the agent with a single belief greatly improved alignment for topics related in the belief network, and not for topics outside the network. These results suggest a novel path for human-LLM belief alignment in work seeking to simulate and understand patterns of belief distributions in society.

Natural language (NL) has long been the predominant format for human cognition and communication, and by extension, has been similarly pivotal in the development and application of Large Language Models (LLMs). Yet, besides NL, LLMs have seen various non-NL formats during pre-training, such as code and logical expression. NL's status as the optimal format for LLMs, particularly in single-LLM reasoning and multi-agent communication, has not been thoroughly examined. In this work, we challenge the default use of NL by exploring the utility of non-NL formats in these contexts. We show that allowing LLMs to autonomously select the most suitable format before reasoning or communicating leads to a 3.3 to 5.7\% improvement in reasoning efficiency for different LLMs, and up to a 72.7\% reduction in token usage in multi-agent communication, all while maintaining communicative effectiveness. Our comprehensive analysis further reveals that LLMs can devise a format from limited task instructions and that the devised format is effectively transferable across different LLMs. Intriguingly, the structured communication format decided by LLMs exhibits notable parallels with established agent communication languages, suggesting a natural evolution towards efficient, structured communication in agent communication.

Should we be concerned about our voice being sourced for AI audiobooks? Kurt "CyberGuy" Knutsson delves into the new technology. Do you love reading yet struggle to find the time for it? Don't worry, you can still enjoy a good book without having to sit down and read. Audiobooks are a convenient way to experience a good story while you're doing other things.

Solar-powered balloons floating in the stratosphere have recorded low-frequency sounds of mysterious origin. "When we started flying balloons years ago, we didn't really know what we'd hear," says Daniel Bowman at Sandia National Laboratories in New Mexico. "We learned how to identify sounds from explosions, meteor crashes, aircraft, thunderstorms and cities. But virtually every time we send balloons up, we find sounds that we cannot identify." Bowman and his colleagues measured infrasound signals – sounds with a frequency so low they are inaudible to human ears – using solar-powered balloons floating 20 kilometres high.

But how do you describe what you saw? Your answer is probably dependent on the time you live in. In 1561, you might have called the weird flying thing a heavenly portent. In the U.K., just before the start of World War I, you would probably say you'd been startled by an unexpected zeppelin. During the Cold War era, you might have called the thing a flying saucer of possible alien origin, or perhaps a secretive Soviet spy weapon: objects that fell into the category of UFOs.

The times sure are a-changing. E3's always been known as a console-centric gaming show, and it definitely still is on the surface. Given the infiltration of AMD's APUs into the Xbox One and PlayStation 4, and the resurgence of PC gaming, plus Microsoft's ambitious Xbox Play Anywhere program, most of the blockbuster games announced for consoles at E3 actually wind up coming to PCs, too. We've sifted through all the new games at the E3 events from EA, Microsoft, Bethesda, Ubisoft, Sony, and The PC Gaming Show to find all the PC gems hidden among the console rubble. These are the E3 reveals that PC gamers need to know about. Wolfenstein: The New Order is one of the best single-player shooters of the past decade, and now B.J. Blazkowicz is back for more ludicrous-yet-heartfelt Nazi-stomping action.
