Congress Summons CEOs of Discord, Steam, Twitch, and Reddit Over Online Radicalization

The House Oversight Committee has summoned the CEOs of Discord, Steam, Twitch, and Reddit to testify on October 8th regarding the radicalization of online forum users on their platforms. The investigation stems from the killing of right-wing activist Charlie Kirk, with the suspect allegedly using Discord to discuss the event. These platforms have a history of hosting extremist content, with past incidents including the 2017 Unite the Right rally and the 2022 Buffalo and Highland Park shootings linked to their use.

Self-Healing Organogel Stretches 46x its Size and Repairs Itself

Scientists in Taiwan have created a self-healing organogel that can stretch up to 46 times its original length. Even when broken, it repairs itself completely within 10 minutes at room temperature. This remarkable material combines covalently linked cellulose nanocrystals and modified mechanically interlocked molecules (MIMs) acting as artificial muscles. These muscles make the gel responsive to external forces, changing color from orange to blue depending on its state. Its self-healing and color-changing properties show promise for applications in flexible electronics, soft robotics, and anti-counterfeiting.

Ant Queens Cloning Males of a Different Species: Rewriting the Rules of Reproduction

Iberian harvester ant (Messor ibericus) queens are defying reproductive biology norms by cloning males of an entirely different species, Messor structor. Researchers discovered isolated M. ibericus colonies thriving without nearby M. structor populations. This led to the astonishing revelation that M. ibericus queens produce male M. structor offspring, which then father the colony's workers. This is the first documented case of an animal producing offspring from another species as part of its normal life cycle, challenging established understanding of species barriers and highlighting the unexpected complexity of natural cooperation and conflict.

YouTube View Count Drop: Are Ad Blockers to Blame?

YouTube View Count Drop: Are Ad Blockers to Blame?

Many YouTubers have recently reported significant drops in video view counts. The most plausible explanation points to YouTube not accurately counting views from users with ad blockers enabled, a potential escalation in YouTube's ongoing battle against ad blockers. Several creators noticed a roughly 50% drop in computer views, while mobile and tablet views remained steady. While YouTube denies a systemic issue, it acknowledges that ad blockers can impact view count accuracy. Other explanations, such as seasonal viewing habits and platform competition, exist, but the ad blocker theory seems the most likely, especially since ad revenue hasn't decreased.

A Flawed Falsification: Re-examining the Real-Number Quantum Theory Experiment

2025-09-17

Renou et al.'s 2021 Nature paper claimed that quantum theory based on real numbers can be experimentally falsified. This post argues otherwise. The paper proposed a test to distinguish between a full quantum gateset using complex numbers and a real-only subset. However, the author demonstrates that a real-only quantum computer, leveraging entanglement, can pass the test. The crucial, hidden assumption is that participating quantum computers begin without entanglement—a detail buried in the supplementary materials, severely undermining the experiment's validity.

Verizon Merger Faces California Headwinds Over DEI Policies

Verizon's acquisition of Frontier Communications is facing a hurdle in California due to conflicting Diversity, Equity, and Inclusion (DEI) policies. To secure FCC approval, Verizon eliminated its DEI programs, a move now clashing with California law. The California Public Utilities Commission (CPUC) demands specifics on Verizon's compliance with state regulations regarding supplier diversity and employment reporting, in the absence of these programs. While Verizon has secured approvals from eight states, the FCC, and the DOJ, California's approval remains uncertain, potentially impacting Verizon's goal of statewide free internet access next year.

Denmark's HPV Vaccination Program Nearly Eradicates Two Major Cancer-Causing Strains

Research published in Eurosurveillance shows that Denmark has virtually eliminated infections with the two most prevalent cancer-causing strains of human papillomavirus (HPV) since the vaccine's introduction in 2008. Analysis of cervical cell samples from Danish women aged 22-30 (2017-2024) revealed that HPV16/18 infection rates in vaccinated women plummeted from 15-17% to less than 1%. This demonstrates not only individual protection but also herd immunity, reducing overall HPV16/18 circulation. However, roughly one-third of screened women still had infections with high-risk HPV types not covered by the initial vaccine. This is expected to decrease as women vaccinated with the newer nine-valent vaccine reach screening age, potentially prompting a review of cervical cancer screening guidelines.
