Study Examines Short-Form Video Effects on Youth
A research team led by health economist Marlene Ebster conducted a meta-study titled “Taming the endless scroll?” examining the effects of short-form videos (TikTok, Instagram Reels, YouTube Shorts) on attention and emotional well‑being in adolescents and young adults. The study focused on youth, with an average participant age of 16.8 years. Ebster (first author) and co-authors Sebastian Schmidt, Michael Lauerer and Eckard Nagel are affiliated with the University of Bayreuth; Ebster is pursuing a PhD at the University of Queensland researching digital addictive behaviors. The article outlines the research questions about attention, reward processing and self-regulation related to the ‘endless scroll’ short-video format and situates TikTok’s origin with ByteDance in 2016.
A meta-study about short-form video impacts on adolescents can influence public perception, platform policy and regulatory scrutiny of youth-targeted content and attention-based monetization, but it is not an immediate industry-shifting announcement.

Study Examines Short‑Form Videos' Impact on Youth
A research team led by health economist Marlene Ebster carried out a meta-study titled "Taming the endless scroll?" examining short‑form video formats (TikTok, Instagram Reels, YouTube Shorts) and their effects on attention and emotional wellbeing in adolescents and young adults. The paper's authors include Marlene Ebster, Sebastian Schmidt, Michael Lauerer and Eckard Nagel; the meta‑analysis focused on users with an average age of 16.8 years. Ebster — affiliated with the University of Bayreuth and a PhD candidate at the University of Queensland — discusses the study's scope and the public debate about short videos and youth, without definitive claims in this article about specific long‑term neurological damage. The piece was published by t3n / MIT Technology Review on 2026-06-29.
Engagement Trap in Short Videos: ADHS Users Most Affected
A study by TU Graz researchers reveals that short-video platforms like TikTok, Instagram Reels, and YouTube Shorts create an 'engagement trap' that disproportionately affects individuals with ADHD. The algorithmic feeds, designed to maximize dwell time, undermine users' ability to intentionally stop using the platforms, leading to a loss of control. ADHD sufferers show greater difficulty in perceiving elapsed time and breaking the endless scroll cycle, resulting in regret and guilt. The EU is currently scrutinizing infinite scrolling, autoplay, and personalized recommendation systems. Researchers suggest limiting videos per session and displaying time to mitigate negative impacts. This research highlights the broader societal concerns around addictive design patterns in social media.
Anthropic's Claude Integrates with Google Docs, Sheets, Slides
Anthropic has integrated its Claude AI assistant directly into Google Docs, Sheets, and Slides, appearing as a sidebar alongside Google's Gemini. This public beta is available for paying Claude customers via Google Workspace Marketplace add-ons. Claude can edit text, create formulas, pivot tables, and charts, and check slide layouts. Users can control its autonomy, with a default approval mode and an 'Accept all edits' mode for batch tasks. Team and enterprise admins must enable new Google Workspace connectors. A guest column by Ting Wasner-Lian analyzes Google's strategic decision to host a competitor, arguing that Google's subscription model profits regardless, and locking out Claude could drive users to Microsoft 365. The article compares this to Alibaba's DingTalk, open to external AI models, and contrasts it with SAP's data access fees, citing Celonis's lawsuit.
