Vestigial Ear Muscles Activate During Effortful Listening

A new study reveals that human auricular muscles, once used to move our ears, reactivate during challenging listening tasks. Scientists used electromyography to measure muscle activity while participants listened to audiobooks with competing sounds. The results showed increased activity in the superior auricular muscles when hearing was difficult, suggesting these vestigial muscles may play a role in attentional mechanisms. While the muscle movements are minuscule and likely don't improve hearing, their activation could serve as an objective measure of listening effort.

LLMs Exacerbate the Underutilization of Libraries

2025-06-20

Libraries are underutilized, due to factors like the enjoyment of coding over reading documentation, the Dunning-Kruger effect underestimating library complexity, and internal projects competing with libraries. LLMs worsen this. While 'vibe coding' with LLMs is fun and efficient, the output often pales in comparison to battle-tested libraries. LLM-generated code is susceptible to prompt engineering limitations, whereas library creators possess deeper problem understanding and can leverage LLMs to generate higher-quality code. Ironically, excessive reliance on LLMs for code generation can be perceived as innovation, creating perverse incentives and further exacerbating the problem. For complex tasks, prioritizing established libraries over direct LLM usage is crucial.

Getting LLMs to Generate Funny Memes: Surprisingly Hard

A University of Waterloo intern attempted to build an app using LLMs and the Greptile API to generate memes that roast GitHub repositories. The process proved unexpectedly challenging. Directly prompting the LLM for roasts yielded generic results. The solution involved separating the task into code analysis (using Greptile to pinpoint specific issues) and roast generation (using the LLM to create targeted humor). Image generation proved difficult due to limitations in handling text, leading to the use of pre-built meme templates and node-canvas for text insertion. Despite the hurdles, the project culminated in reporoast.com, a website capable of generating custom code-roasting memes.

French Modernists and the Mass Media: A Love-Hate Relationship

This essay explores the complex relationship between 19th-century French modernist writers and the mass media, particularly newspapers. From Baudelaire to Proust, they both loathed the negative impacts of newspapers (e.g., inciting crime, suppressing literature) and were deeply influenced by them, utilizing their platforms for creation and promotion. Newspapers served as both a crucible of modernity and a laboratory for literary innovation. Writers struggled against them while actively integrating them into their work; Mallarmé's groundbreaking poem *A Throw of the Dice* was published in the commercial magazine *Cosmopolis*. Ultimately, the author argues that in the face of the internet's information deluge, we can learn from the French modernists' experience, maintaining artistic independence while skillfully leveraging new media.

WebAssembly's Memory64: A Trade-off Between Speed and Memory

WebAssembly's Memory64: A Trade-off Between Speed and Memory

WebAssembly recently introduced Memory64, adding support for 64-bit pointers. Surprisingly, however, Memory64 doesn't result in performance gains; instead, due to limitations in hardware, operating systems, and WebAssembly's design, it can run 10% to over 100% slower than 32-bit mode. This is because 32-bit mode allows browsers to reserve 4GB of memory, eliminating the need for bounds checks. Memory64, however, requires bounds checks, adding computational overhead. Therefore, unless you need more than 4GB of memory, Memory64 isn't the optimal choice. Future improvements in hardware and WebAssembly might improve Memory64's performance.

Mars Dichotomy Boundary Eroded Hundreds of Kilometers

Mars Dichotomy Boundary Eroded Hundreds of Kilometers

New research suggests Mars' iconic dichotomy boundary, separating the higher southern hemisphere from the lower northern one, may have receded hundreds of kilometers due to water erosion. Researchers analyzed data from the Mars Express and Mars Reconnaissance Orbiter, finding that thousands of buttes and mesas near Mawrth Vallis, situated at the dichotomy boundary, share a similar height with a nearby higher-elevation plateau, indicating they are remnants of a larger plateau eroded away. This massive erosion suggests an active water cycle early in Mars' history, consistent with the theory of a northern ocean but also potentially caused by other hydrological processes like ice cap melting. The finding offers new clues about early Martian climate and geological evolution, adding to evidence for a past ocean but also raising new questions.

Iron Age Society Centered on Women: Ancient Genomes Reveal a Matrilocal Past

An international team, led by Trinity College Dublin, has unearthed a fascinating glimpse into Britain's Iron Age through ancient DNA. Analysis of over 50 genomes from a Dorset burial site revealed a society structured around female lineage. The study indicates that husbands joined their wives' communities, with land potentially inherited through the maternal line, a system called matrilocality. This pattern wasn't unique to Dorset; similar findings in other Iron Age cemeteries across Britain suggest a widespread phenomenon, challenging traditional views of gender roles and highlighting the significant social and political influence of women in this era.

The 2025 State Of Open conference highlighted the plight of open source maintainers: volunteers pour countless hours into projects with little support, leading many to quit or consider quitting. The resignation of Asahi Linux lead Hector Martin due to burnout and demanding users exemplifies this crisis. Maintainers face pressure from users, endless requests, and occasional negativity. Even with minimal corporate sponsorship, the demands far outweigh the support. Surveys reveal many maintainers considering quitting, and many projects may become unmaintained. The problem isn't solely financial; it also requires more contributors to share non-coding tasks like community management and fundraising. But change needs a catalyst—perhaps a major project collapse will finally convince people that paying open source maintainers is crucial.
