Bacteria Build Living Gels in Polymers: A New Twist on Biofilms

Caltech and Princeton University scientists have discovered that bacteria growing in polymer solutions, like mucus, form long, intertwined cables—a kind of ‘living Jell-O.’ This is significant for understanding diseases like cystic fibrosis, where thickened lung mucus fosters dangerous bacterial infections. The discovery also has implications for studying biofilms (the slimy coatings on surfaces) and their industrial impacts. The researchers found that external pressure from the polymers forces the bacterial cells together. A theoretical model accurately predicts when these cable structures will form. The reason for cable formation remains a mystery: it may be a bacterial defense mechanism or conversely, a way for the body to expel the infection more easily. This unexpected finding opens up new avenues of research into bacterial growth and biofilm control.

The Rise of AI Slop: How to Fight Back and Profit

Blogger Ben Congdon observes the proliferation of low-quality AI-generated content, which he terms "AI slop," across the internet. While seemingly convincing at first glance, closer inspection reveals its formulaic nature and lack of originality. He argues against directly copying and pasting AI-generated content, suggesting creators should use AI tools for assistance but meticulously edit and maintain a unique personal voice. He further proposes that creating high-quality content and building a personal brand are key to remaining competitive in the age of AI, and that influencing AI training datasets can even shape the future direction of AI.

Vinyl's Revival: A Heideggerian Look at Music in the Spotify Age

In 2023, vinyl record sales surpassed CDs for the first time since 1987, prompting reflection on the nature of musical experience. Drawing on Heidegger's concept of 'de-severance' from *Being and Time*, the article explores the 'de-presence' inherent in streaming services like Spotify: music consumption becomes fragmented, personalized, and lacks the tactile, visual, and social engagement associated with vinyl. Vinyl's resurgence signifies a yearning for a more experiential and communal approach to music.

Prolog: The Elegance of Declarative Programming

2025-01-26

This article delves into the simplicity and power of Prolog, a logic programming language. Unlike popular imperative languages (like Python, Java), Prolog employs a declarative paradigm, focusing on describing the problem rather than specifying the solution steps. The author demonstrates Prolog's advantages in conciseness and adaptability by comparing Prolog and Kotlin implementations of an authorization system. The Prolog code is significantly more compact, and modifications are easier when requirements change (e.g., adding a time dimension). While Prolog has a steeper learning curve, mastering it broadens programming perspectives and helps maintain system simplicity.

White House Seeks Oracle's Help to Save TikTok from US Ban

To prevent a nationwide ban, the White House is negotiating with Oracle and other investors to transfer control of TikTok's algorithm, data collection, and software updates to American companies. While ByteDance, TikTok's Chinese owner, would retain a minority stake, US investors would hold a majority. This aims to comply with US law mandating TikTok's separation from its Chinese parent company. However, the deal faces hurdles, including TikTok's high valuation and securing congressional approval. Recent signals from Chinese regulators suggest they won't block a majority US ownership, but uncertainties remain about the long-term commitment of the Trump administration and the cooperation of Apple and Google.

Base-Rate Blindness: When Rare Events Surprise Us (and How AI Might Exploit It)

2025-01-26

This essay uses the astonishing feats of pickpocket Apollo Robbins to illustrate the concept of 'base-rate blindness'. The author argues that we underestimate the probability of rare events because we tend to ignore base rates – the prior probability of an event. Using personal anecdotes, like a surprising moose encounter in Colorado, and the academic world's underestimation of deception, the author shows how ignoring base rates can lead to dangerous consequences. The essay concludes with a provocative question: Are we base-rate blind to the potential risks of AI, distracted by the hype and pleas for regulation?

Anomalous Tokens in DeepSeek: A Catalog of Glitches

A researcher has uncovered a trove of 'anomalous tokens' within the open-source large language model DeepSeek-V3 and r1. These tokens, when inputted, cause the model to exhibit bizarre behavior, such as replacing words with unusual Unicode characters, acronyms, or emojis. The researcher systematically tested each token from DeepSeek's vocabulary, identifying and categorizing these glitches. Some tokens, dubbed 'fragment tokens,' only show anomalies in specific contexts. Others, like 'Nameeee' and 'EDMFunc', consistently produce peculiar substitutions. 'Nameeee' frequently yields 'M'-related words or symbols, while 'EDMFunc' favors words starting with 'H' and Japanese names. Numerous non-English anomalous tokens, primarily from Cebuano and other Philippine languages, were also found. Special tokens like '<｜end of thinking｜>' can further disrupt the model's functionality. This research offers valuable insights into the inner workings of LLMs and opens avenues for further investigation.
